Chapter 10: Stress, Health, and Coping Stress vs. Stressor * Stressor: Anything that causes stress (an event, situation, or demand). * Example: Exams, losing a job, relationship problems. * Stress: The body’s response to a stressor. * Example: Feeling anxious, increased heart rate. Types of Stressors 1. Catastrophe * Large, unpredictable events affecting many people. * Example: Natural disasters, wars. 2. Significant Life Changes * Major events that require adjustment. * Example: Divorce, moving, starting college. 3. Daily Stressors * Small everyday problems. * Example: Traffic, homework, arguments. Sympathetic Nervous System & Fight-or-Flight * Activates during stressful situations. * Prepares the body to react. * Causes: * Increased heart rate * Faster breathing * More energy released General Adaptation Syndrome (GAS) A three-stage response to stress: 1. Alarm: Body reacts to stress. 2. Resistance: Body tries to adapt and continue functioning. 3. Exhaustion: Long-term stress drains resources. Type A vs. Type B Personality Type A: * Competitive * Impatient * Time-urgent * More stress-prone Type B: * Relaxed * Patient * Less stressed Immune System & Stress * Long-term stress weakens the immune system. * Makes the body more vulnerable to illness. Locus of Control Internal locus of control: * Belief that you control your outcomes. External locus of control: * Belief that outside forces control outcomes (luck, fate). Managing Stress * Aerobic exercise * Meditation * Relaxation techniques * Spending time with pets * Social support * Healthy sleep habits ⸻ Chapter 11: Social Psychology Fundamental Attribution Error * Tendency to explain others’ behavior by personality instead of situations. * Example: “He’s lazy” instead of considering he may be exhausted. Attitudes * Feelings and beliefs that influence behavior. * Made of: * Thoughts * Feelings * Actions Cognitive Dissonance * Mental discomfort from having conflicting beliefs or behaviors. * Example: Knowing smoking is unhealthy but continuing to smoke. Social Contagion * Spread of behaviors, emotions, or ideas through groups. * Example: Panic spreading through a crowd. Classic Studies Asch’s Line Study * Showed people may conform to a group even when the group is wrong. Milgram’s Obedience Study * Showed people may obey authority figures even when uncomfortable. Social Facilitation vs. Social Loafing Social Facilitation: * Performance improves when others are watching. Social Loafing: * People put in less effort when working in groups. Deindividuation * Losing self-awareness and responsibility in a group. * Example: Crowds acting differently than individuals. Ingoups vs. Outgroups Ingroup: * Group you belong to. Outgroup: * Group you see as different. Can lead to: * Bias * Stereotypes * Prejudice Passionate vs. Companionate Love Passionate Love: * Intense attraction and excitement. Companionate Love: * Deep affection, trust, and commitment. Altruism & Bystander Effect Altruism: * Helping others without expecting a reward. Bystander Effect: * People are less likely to help when others are present. ⸻ Chapter 12: Personality Personality * Patterns of thoughts, feelings, and behaviors that make someone unique. Psychoanalytic Theory (Freud) Id * Wants immediate pleasure. * “I want it now.” Ego * Reality-based decision maker. * Balances id and superego. Superego * Morals and rules. Defense Mechanisms Ways the mind protects itself from anxiety. Examples: * Denial: Refusing to accept reality. * Projection: Blaming feelings on others. * Rationalization: Creating excuses. Humanistic Theory * Focuses on personal growth and reaching full potential. * Carl Rogers developed Person-Centered Therapy. Trait Theory (Big Five) Five major personality traits: OCEAN * Openness * Conscientiousness * Extraversion * Agreeableness * Neuroticism Spotlight Effect vs. Narcissism Spotlight Effect: * Believing others notice you more than they actually do. Narcissism: * Excessive self-focus and feeling superior. Kruger-Dunning Effect * People with low ability may overestimate their skills. Individualistic vs. Collectivistic Cultures Individualistic: * Focus on independence and personal goals. Collectivistic: * Focus on family, groups, and cooperation. ⸻ Chapter 13: Psychological Disorders Psychological Disorder * A pattern of thoughts, feelings, or behaviors that causes distress or problems functioning. Anxiety Disorders * Excessive fear or worry. Examples: * Generalized anxiety disorder * Panic disorder * Phobias OCD * Obsessions (unwanted thoughts) * Compulsions (repetitive behaviors) PTSD * Stress disorder after experiencing or witnessing trauma. Substance Use Disorder * Difficulty controlling substance use despite negative effects. Major Depressive Disorder Symptoms include: * Persistent sadness * Loss of interest * Changes in sleep or energy Bipolar Disorder * Episodes of depression and mania. * Mania involves unusually high energy, mood, or activity. Suicidal Ideation * Thoughts about suicide. (Important: any concerns about safety should be taken seriously and support should be reached out to.) Schizophrenia * Disorder involving: * Hallucinations * Delusions * Disorganized thinking Personality Disorders Antisocial PD * Disregard for others’ rights and social rules. Narcissistic PD * Extreme need for admiration and lack of empathy. Borderline PD * Difficulty with emotions, relationships, and sense of self. ⸻ Chapter 14: Treatment Psychotherapy * Treatment using psychological methods to improve mental health. Types of Psychotherapy Psychoanalysis/Psychodynamic * Focuses on unconscious conflicts and past experiences. Client-Centered/Humanistic * Focuses on acceptance, growth, and self-understanding. Behavioral Therapy * Changes behaviors through learning principles. Cognitive Therapy * Changes unhealthy thought patterns. Cognitive Behavioral Therapy (CBT) * Combines changing thoughts and behaviors. Family Therapy * Works with family relationships. Group Therapy * Therapy with multiple people. Evidence-Based Practice * Treatments supported by scientific research. Therapeutic Lifestyle Change Improving mental health through: * Exercise * Sleep * Nutrition * Social connection Biomedical Treatments Medication * Treats symptoms through biological processes. ECT (Electroconvulsive Therapy) * Uses controlled electrical stimulation to treat severe depression. Psychosurgery * Surgery involving the brain (rare). TMS (Transcranial Magnetic Stimulation) * Uses magnetic stimulation to affect brain activity. ⸻ Quick Test Tips: * Stress = response, Stressor = cause * Asch = conformity * Milgram = obedience * Big Five = OCEAN * Id = pleasure, Ego = reality, Superego = morals * CBT = thoughts + behaviors * Bystander effect = less helping in groups

​​2023 Semester Only Grade 7th/8th Physical Education Content Review Key Concepts Content • Responsible behaviors • Team Building • Responsible Behaviors o Demonstrate acceptance and respect for people with diverse backgrounds and abilities during fitness activities. Develop strategies for including everyone. o Demonstrate responsible behaviors during fitness activities. Examples of responsible behaviors are controlling emotions, resolving conflicts, respecting opponents and officials, and accepting both victory and defeat • Team Building o Characteristics of High-Performing Teams - Most members of high-performing teams report that it’s fun and satisfying to work on collaborative teams because they are asked to contribute at their highest potential and they learn a lot along the way. Characteristics of high-performing teams include the following: ▪ People have solid and deep trust in each other and in the team’s purpose — they feel free to express feelings and ideas. ▪ Everybody is working toward the same goals. Everyone places the team first. ▪ Team members are clear on how to work together and how to accomplish tasks. ▪ Everyone understands both team and individual performance goals and knows what is expected. ▪ Individuals contribute to the team based on their unique strengths ▪ The team engages in extensive discussion, and everyone gets a chance to contribute. ▪ Disagreement is viewed as a good thing and conflicts are managed. Criticism is constructive and is oriented toward problem solving and removing obstacles. ▪ The team makes decisions when there is natural agreement — in the cases where agreement is elusive, a decision is made by the team lead or executive sponsor, after which little second-guessing occurs. ▪ Each team member carries his or her own weight and respects the team processes and other members. ▪ The leadership of the team shifts from time to time, as appropriate, to drive results. ▪ No individual members are more important than the team. • Warm-up • Cool-Down • Heat Cramps • Hear Exhaustion • Heat Stroke • Dehydration • Proper Attire (clothes and shoes) - color and type of clothing to be worn during exercise in different climates • Proper Hydration - drink water before, during and after exercise especially during hot weather • Warm-up: Gentle exercises that get the heart and muscles ready for moderate to vigorous physical activity. You know when you are warmed up when you begin to sweat and breath more heavily. o Walking or jogging for 5-10 minutes is recommended • Cool-Down: Gentle exercises that let the body adjust to ending a workout. Should last for 5-10 minutes allowing your heart rate and breathing to return to normal. o Include light stretching in your cool down to help muscles relax and not feel stiff or sore afterward. • Heat-Related Illnesses o Heat Cramps: Painful, brief muscle cramps that occur during exercise in a hot environment, caused by dehydration o Heat Exhaustion: A heat illness caused by the body overheating. Symptoms include heavy sweating, dizziness, weakness and rapid pulse o Heat Stoke: A health illness caused by the bodies inability to regulate its temperature. Symptoms include hot, dry skin, elevated body temperature, lack of sweat, hallucinations o Dehydration: Excessive loss of body fluid • Aerobic exercise • Anaerobic exercise • Pedometer • Vigorous • Moderate • FITT • Aerobic Exercise - Rhythmic activity that uses large amounts of oxygen and works the heart and lungs. • Anaerobic Exercise - Activities performed (without oxygen) consists of brief strength-based activities. • Heart Rate - The number of times your heart beats per minute. • Moderate physical activity - An activity with intensity equal to brisk walking. Activities of moderate intensity can be performed for relatively long periods of time without fatigue. • Vigorous physical activity - Movement that expends more energy or is performed at a higher intensity than brisk walking. • Forehand stroke • Backhand stroke • Forehand strokes (racquet sports) are where the front of the hand leads the stroke. o To strike the ball players should stand with their opposite shoulder facing the net, swing from low to high and follow through. Opposite footsteps toward the net. o Follow through by driving the racket forward so that it ends up above the shoulders, pointing up to the sky and in the direction of the ball you just hit. o Hitting the ball too late may cause the ball to land out of bounds. • Backhand strokes (racquet sports) are where the back of the hand leads the stroke. o Begin with a balanced ready position. Transition from large steps to smaller steps as a player closes in on the ball will help maintain balance. Step toward the net with the foot on the same side. o As the ball approaches, the player must move to intercept it, the shoulder must turn to begin the backswing. As a player sets to hit the ball, the backswing is complete. o The path of the racket extends along the intended flight of the ball as long as possible. Contact point for a one-handed backhand is further in front of the body than in a two-handed stroke. o The face of the racket remains vertical through the contact zone. The follow through is high. • CPR • Aquatic safety • Cardiopulmonary Resuscitation (CPR) o Hands-Only CPR Steps: ▪ Call 911 and push hard and fast in the center of the chest (100 compressions a minute) • Aquatic Safety o Swim with a buddy o Take swimming, diving, and water safety or rescue classes to learn the skills to swim and dive safely. o Never swim under the influence of alcohol or drugs o Make sure to check the depth of the water before diving • Free Pass • Penalty try • Rugby Game Play: o free pass: is used to start the match or restart after a “try”. It starts from the center of the field at the halfway line at the beginning of each half. From the touch line (at the place where the ball went into touch) when the ball goes into touch (put into play), and from where the referee makes a mark when an infringement has taken place. o To score in flag rugby you must be on or cross the end zone with your flag on, touch the ball to the ground and say “try”. o A penalty try will be awarded if a try would have been scored if there was not foul play by the defending team. o When a try is scored, the game is restarted by a free pass from the center of the pitch by the non-scoring team. o The player taking the free pass must start with the ball in both hands and, when instructed by the referee who will declare “Play”, pass the ball sideways or backwards through the air to a team-mate. • Rules of the game • Basketball Rules: o The game starts with a jump ball then alternate possession begins. o Five players play on the floor at a time. Players’ positions consist of guards, forwards and a center, o Traveling- is having possession of the ball and moving without dribbling, resulting in a turnover. • Rules • Ultimate Frisbee is a non-contact field sport that combines elements of soccer, football and basketball. The object of the game is for a team to pass the disc from player to player until a pass is completed to a teammate in the end zone resulting in a score. Teams consist of 7 players. • How the Game is Played: o The game is played to 13 points or until a certain amount of time has passed. o All players from both teams begin each point in their respective end zones. Play is initiated with a “pull” from the defensive team’s end zone. The disc is passed from player to player down the field. o Once the disc is caught the “handler” must come to a complete stop. He/she may pivot but must maintain one planted foot at all times (even on the follow through). o The thrower or “handler” has ten seconds to throw the disc once caught. o A point is scored when a receiver catches the disc in the end zone. • Warm-up • Cool-Down • Heat Cramps • Heat Exhaustion • Heat Stroke • Dehydration • Proper Attire (clothes and shoes) - color and type of clothing to be worn during exercise in different climates • Proper Hydration - drink water before, during and after exercise especially during hot weather • Warm-up: Gentle exercises that get the heart and muscles ready for moderate to vigorous physical activity. You know when you are warmed up when you begin to sweat and breath more heavily. o Walking or jogging for 5-10 minutes is recommended • Cool-Down: Gentle exercises that let the body adjust to ending a workout. Should last for 5-10 minutes allowing your heart rate and breathing to return to normal. o Include light stretching in your cool down to help muscles relax and not feel stiff or sore afterward. • Heat-Related Illnesses o Heat Cramps: Painful, brief muscle cramps that occur during exercise in a hot environment, caused by dehydration o Heat Exhaustion: A heat illness caused by the body overheating. Symptoms include heavy sweating, dizziness, weakness and rapid pulse o Heat Stoke: A health illness caused by the bodies inability to regulate its temperature. Symptoms include hot, dry skin, elevated body temperature, lack of sweat, hallucinations • Dehydration: Excessive loss of body fluid • Alcohol • Smoking • Effective Communication • Alcohol o Underage drinking is considered illegal o There are laws about alcohol consumption o Alcohol slows down the ability to think clearly • Smoking o Smoking is the primary risk factor in respiratory diseases including emphysema and bronchitis o Cigarette smoking causes the heartbeat to increase the heart rate o Nicotine in cigarettes stimulates the heart to beat faster, which increases the heart’s need for more oxygen. Carbon monoxide replaces the oxygen in the blood forcing the heart to work harder. • Effective Communication o Includes: ▪ being respectful ▪ Actively listening ▪ Using assertive communication skills when needed • PACER • Push-ups • Curl-ups • Sit and Reach • Fitness Test o PACER: Performed to measure cardiorespiratory fitness o Push-ups: Use to measure muscular strength and endurance o Curl-ups: Used to measure abdominal muscular endurance and muscular strength o Sit and Reach: Performed to measure a student’s flexibility • Digital Citizenship • Digital Footprint • Digital Citizenship: is a safe, responsible, and respectful use of technology • Digital Footprint: is essentially a history of everything you’ve ever done online. Everything you post and do online can follow you through middle and high school, college, and even when you get a job. It has the potential to contribute positively or negatively to your digital reputation. • Positions in Hockey • How the Game is played • Scoring • Hand Placement • How the game of hockey is played o Street hockey is played very similar to ice hockey using the same rules and similar style of play. The only difference is that the players are using a ball instead of a puck and are running on firm ground rather than skating on ice. The game is played with 5 players and a goalie. There are five players on the court at a time with a goalie. Three forwards (2 wingers and a center) and two defenders. • Object of the game o Hockey is a fast-paced team sport, and the object is to outscore your opponent in the allotted time. • Start to play o A face-off will occur after every goal scored and to start off each period. The referee will drop the ball in-between the two centers who are facing each other. There are three periods in a game. • Out of Bounds o If the ball is hit out of bounds, then the opposing team may pass it back in from the side lines. • Scoring o a goal is made when a player either knocks down a cone, or if the ball crosses the goal line. Both goals and assists will be rewarded when scorekeeping during tournament play at the end of the unit. • How the game is played • Players and positions • Basic Skills • How the game of volleyball is played: o A game is played to 25 points. A team must win by 2 points and is called a set. A match is 3 out of 5 sets. o The server must stand anywhere behind the end line on his/her side of the court prior to the serve. The ball may be served underhand or overhand. The player who serves is in the right back position. o Each team may only hit the ball 3 times on its side before the ball must pass over the net. o The teams will rotate clockwise each time they win the serve. o A point is scored every time a ball is not returned properly into the opponent’s court, this is called rally scoring. Thus, both serving and receiving teams can score points. o If the ball hits the line it is considered, in bounds or good. • Players and Positions: o Setters – player who “sets” the ball with an “overhead pass” for a teammate to hit, the setter normally runs the offense o Hitter - the spiker or attacker o Outside hitter - A left or right-front attacker normally taking an approach which starts from outside the court o Libero - defensive specialists, designated for back row only, and wear a different colored jersey. The libero may serve for one player she is substituting for per game. o Blocking - A defensive play by one or more players meant to deflect a spiked ball back into the hitter’s court. To block, move your body in front of the hitter, keep arms in front, straight, palms facing the ball. • Players • Rules • Cues for throwing in flag football • Cues for catching • Scoring • Flag Safety • Defensive Strategy • Flag Football Players Include o Quarterback - The offensive person who is in charge of advancing the ball down the field (either by hand-off or pass), in order to gain yardage, a first down, or to score a touchdown. The QB also initiates and calls the plays. o Center - The offensive person who is in charge of “snapping” or “hiking” the football to the Quarterback. (“Hiking” means to hand the ball between the legs) o Receiver - The offensive person who runs a route down the field to catch a pass from the quarterback in order to gain yardage, a first down, or to score a touchdown • Rules o Interception - When the defensive player catches a pass intended for an offensive receiver o Sack - When the Quarterback has his flag pulled by the defense behind the line of scrimmage o Fumble - When the ball is dropped after being in possession o Line of Scrimmage - Each play starts on the line of scrimmage. The line of scrimmage is the imaginary line where the nose of the ball is placed to separate the offensive team from the defensive team. • Downs - The offensive team then has 4 “downs” to advance the ball to the next 1st down marker. Teams may advance the ball by passing or rushing • How the game is played • How the game of soccer is played o Soccer is a field game between two teams of up to 11 players. o The purpose of the game is to make goals by dribbling, heading, or volleying the ball into the opponent’s goal while defending the teams own goal from opponents. o The ball is put into play at the beginning of the game when a player kicks the ball into the opponent’s half of the field at a distance of at least the circumference of the ball. The kicking player may not kick the ball twice in a row. o Once the ball is in play, each team tries to advance the ball toward the opponent’s goal to score by dribbling and passing it down the field. o Players are free to play the ball in any direction during play. In typical play, players attempt to create goal scoring opportunities through individual control of the ball, dribbling, passing and taking shots on goal

Hallucinogens Lecture Notes Review

Unit 1: Psychology’s History and Approaches Big Idea: Psychology is the scientific study of behavior and mental processes. This unit asks: Why do people think, feel, and behave the way they do, and how do psychologists study it? 1. Early Schools of Thought Structuralism Focused on breaking conscious experiences into smaller parts. Example: Describing every taste, smell, and feeling while eating pizza. Functionalism Focused on WHY behaviors and thoughts exist. Example: Fear exists because it helps humans survive danger. Connection: Structuralists asked “What are thoughts made of?” Functionalists asked “What purpose do thoughts serve?” 2. Major Psychological Perspectives Biological Perspective Behavior comes from the brain, genetics, and hormones. Example: Depression connected to serotonin levels. Behavioral Perspective Behavior is learned through rewards and punishments. Example: A dog learns tricks because it gets treats. Cognitive Perspective Focuses on thinking, memory, and problem-solving. Example: Why students remember some facts better than others. Humanistic Perspective Humans naturally strive for growth. Example: Trying to achieve goals and improve yourself. Psychodynamic Perspective Unconscious conflicts affect behavior. Example: Getting unusually angry because of hidden stress. Evolutionary Perspective Behaviors developed because they helped survival. Example: Humans naturally fearing dangerous animals. Sociocultural Perspective Behavior is shaped by culture and society. Example: Different cultures have different expectations for personal space. 3. Research Methods Experiment Used to determine cause and effect. Independent Variable What the researcher changes. Dependent Variable What the researcher measures. Example: Studying whether sleep affects test scores. * Amount of sleep = IV * Test score = DV Correlation Shows relationship between variables. Important: Correlation does NOT equal causation. Example: Ice cream sales and drowning both rise during summer. Random Assignment Participants randomly placed into groups. Helps reduce bias. Double-Blind Procedure Neither researchers nor participants know who receives treatment. Prevents expectations from affecting results. BIG AP EXAM CONNECTION The AP exam loves asking: * Which perspective best explains this behavior? * Which research method should be used? * Why doesn’t correlation prove causation? Example: A psychologist studies how rewards affect studying. → Behavioral perspective + experiment Unit 2: Biological Basis of Behavior Big Idea: Your brain, nervous system, hormones, and genetics all shape behavior. The whole unit asks: How do your body and brain create thoughts, emotions, and behavior? 1. Nature vs. Nurture = Who You Are Main Idea: Your behavior comes from BOTH: * Nature = genetics/heredity * Nurture = environment and experiences Example: Someone may inherit anxiety tendencies but stressful experiences can make anxiety stronger. 2. Nervous System Central Nervous System Brain + spinal cord. Peripheral Nervous System Nerves outside the brain and spinal cord. Sympathetic Nervous System Activates during stress. Example: Heart racing before giving a speech. Parasympathetic Nervous System Calms the body afterward. 3. Neurotransmitters Dopamine Reward and pleasure. Example: Social media likes feel rewarding. Serotonin Mood and sleep. Low levels linked to depression. Acetylcholine Movement and memory. Linked to Alzheimer’s disease. GABA Calms nervous system. Low GABA linked to anxiety. 4. Brain Structures Frontal Lobe Decision-making and personality. Occipital Lobe Vision. Temporal Lobe Hearing and memory. Hippocampus Memory formation. Amygdala Fear and aggression. BIG AP EXAM CONNECTION A student panicking before a test: * amygdala activates fear * sympathetic nervous system increases heart rate * adrenaline releases Unit 3: Sensation and Perception Big Idea: Sensation detects information. Perception interprets information. This unit asks: How does the brain create your experience of the world? 1. Sensation Absolute Threshold Smallest amount of stimulation needed to notice something. Example: Hearing a quiet text notification. Difference Threshold Smallest noticeable difference between stimuli. Example: Noticing the TV volume changed. Sensory Adaptation Becoming less aware of constant stimulation. Example: Not noticing your hoodie after wearing it awhile. 2. Vision Rods Help see in dim light. Cones Detect color. Blind Spot Area without receptors. 3. Hearing Frequency Determines pitch. Amplitude Determines loudness. 4. Perception Gestalt Principles The brain organizes pieces into meaningful wholes. Example: Seeing a complete logo even with missing parts. Depth Perception Ability to see distance in 3D. Example: Catching a volleyball. Perceptual Set Expectations affect perception. Example: Misreading a word because you expected something else. BIG AP EXAM CONNECTION The exam often gives optical illusions or perception scenarios. Example: A person stops noticing a strong smell after 10 minutes. → sensory adaptation Unit 4: Learning Big Idea: Behavior changes because of experience. This unit asks: How do humans and animals learn behaviors? 1. Classical Conditioning Learning through association. Pavlov’s Dogs Dogs learned to associate a bell with food. Unconditioned Stimulus Naturally causes response. Conditioned Stimulus Previously neutral stimulus causing learned response. Example: Feeling hungry when hearing the microwave beep. 2. Operant Conditioning Learning through rewards and punishments. Positive Reinforcement Adding something good to increase behavior. Example: Getting money for good grades. Negative Reinforcement Removing something unpleasant. Example: Seatbelt alarm stopping. Punishment Decreases behavior. 3. Observational Learning Learning by watching others. Example: Kids copying influencers online. BIG AP EXAM CONNECTION The AP exam loves reinforcement examples. Example: A student studies harder after praise from parents. → positive reinforcement Unit 5: Cognitive Psychology Big Idea: Humans think, remember, solve problems, and use language. This unit asks: How does the mind process information? 1. Memory Process Encoding Getting information into memory. Storage Keeping information over time. Retrieval Getting information back. 2. Types of Memory Sensory Memory Very brief memory. Short-Term Memory Temporary limited storage. Long-Term Memory Relatively permanent storage. Working Memory Actively using information. Example: Doing math in your head. 3. Forgetting Proactive Interference Old information disrupts new information. Retroactive Interference New information disrupts old information. Example: Forgetting old password after learning a new one. 4. Problem Solving Algorithm Step-by-step method. Heuristic Mental shortcut. Confirmation Bias Looking for information supporting beliefs. Example: Only reading opinions you already agree with. BIG AP EXAM CONNECTION A student mixes up Spanish vocabulary from last year with current vocabulary. → proactive interference Unit 6: Developmental Psychology Big Idea: Humans develop physically, mentally, and socially across life. This unit asks: How do people change from infancy through adulthood? 1. Piaget’s Cognitive Development Sensorimotor Stage Babies learn through senses and actions. Object Permanence Understanding objects still exist when hidden. Example: Babies searching for hidden toys. Preoperational Stage Children use language but think egocentrically. Egocentrism Difficulty understanding another perspective. Example: A child assuming everyone sees exactly what they see. Concrete Operational Stage Logical thinking develops. Formal Operational Stage Abstract thinking develops. Example: Thinking about hypothetical situations. 2. Attachment Strong emotional bond with caregivers. Secure Attachment Healthy trust and comfort. 3. Parenting Styles Authoritative Strict but supportive. Usually healthiest. Authoritarian Strict with little warmth. Permissive Warm but few rules. BIG AP EXAM CONNECTION A teenager exploring identity and future goals. → Erikson’s identity vs role confusion stage Unit 7: Motivation, Emotion, and Personality Big Idea: Motivation drives behavior, emotions affect actions, and personality shapes how people interact. 1. Motivation Drive-Reduction Theory People act to reduce discomfort. Example: Eating when hungry. Maslow’s Hierarchy Basic needs come before higher goals. Example: Someone struggling financially may focus on survival before self-esteem. 2. Emotion Theories James-Lange Theory Physical response first. Example: Heart races THEN fear is felt. Cannon-Bard Theory Emotion and physical response happen together. Schachter Two-Factor Theory Emotion depends on physical arousal plus interpretation. 3. Personality Trait Theory Personality made of stable characteristics. Big Five Traits * openness * conscientiousness * extraversion * agreeableness * neuroticism BIG AP EXAM CONNECTION A student interpreting sweaty palms before a game as excitement. → Schachter two-factor theory Unit 8: Clinical Psychology Big Idea: Psychological disorders affect thoughts, emotions, and behaviors. This unit asks: How are disorders identified and treated? 1. Anxiety Disorders Generalized Anxiety Disorder Constant excessive worry. Phobias Irrational fears. OCD Obsessions and compulsions. 2. Mood Disorders Major Depressive Disorder Persistent sadness and loss of interest. Bipolar Disorder Extreme mood swings. 3. Schizophrenia Disordered thinking and perception. Hallucinations False sensory experiences. Delusions False beliefs. 4

Stimulants, Nicotine, and Hallucinogens Review

VHS Study Guide Psychology WEEK 1: Psychology as a Science The goal of this week is to distinguish between "Pop Psychology" (myths) and "Empirical Science" (facts). 1. The Philosophical Roots & "Big Names" Wilhelm Wundt: Established the first psychology lab (1879). He used Structuralism, trying to map the "structure" of the mind through Introspection (having subjects report every tiny sensation they felt). Sigmund Freud: Founded Psychoanalysis. He believed behavior is driven by the Unconscious mind and childhood traumas. He used dream analysis and "free association." Behaviorism (Watson & Skinner): They rejected Freud. They argued psychology must be an Empirical Science, meaning we only study what we can see and measure. Watson: Famous for the "Little Albert" study (fear conditioning). Skinner: Focused on how rewards/punishments shape behavior (Operant Conditioning). Ivan Pavlov: A physiologist who discovered Classical Conditioning (associating a neutral stimulus, like a bell, with a natural reflex, like drooling). Maslow’s Hierarchy of Needs: A Humanist theory. It’s a pyramid starting with basic survival (food/water) and moving up to Self-actualization (reaching your full potential). 2. The "Brain Traps" (Critical Thinking & Myths) Word-of-Mouth: We believe things just because we’ve heard them a lot (e.g., "We only use 10% of our brain"—FALSE). Desire for Easy Answers: People prefer a "quick fix" (like a 5-minute cure for anxiety) over complex scientific reality. Selective Perception: We only notice things that confirm our existing beliefs. Post Hoc, Ergo Propter Hoc: "After this, therefore because of this." The logical error of assuming that because Event B followed Event A, Event A must have caused it. Inferring Causation from Correlation: The most common exam trap. Just because two variables move together (like heat and crime), it doesn't mean one causes the other. Reasoning by Representativeness: Stereotyping. Thinking a person "looks like" a certain role, so they must be that role (the "Finance Bro" vest example). WEEK 2: Scientific Inquiry and Research This is the "How-To" of psychology. You need to know the difference between just watching people and running a real experiment. 1. Research Methods Naturalistic Observation: Watching subjects in their natural habitat without interfering. High "real world" accuracy, but you have zero control. Case Study (Clinical): An intensive, detailed look at one unique individual (e.g., a person with a rare brain injury). Great for detail, but you can't apply the results to everyone. Archival Research: Looking at old records, newspapers, or medical files to find patterns. Longitudinal vs. Cross-Sectional: Longitudinal: Following the same group of people for 20+ years. (Expensive, but shows true change). Cross-Sectional: Comparing different ages at the same time (e.g., testing 10-year-olds and 50-year-olds today). 2. The Experimental Design (The "Gold Standard") Inductive vs. Deductive: Inductive: Starting with observations $\rightarrow$ forming a theory (Bottom-up). Deductive: Starting with a theory $\rightarrow$ testing it with an experiment (Top-down). Independent Variable (IV): The variable the researcher manipulates (The "Cause"). Dependent Variable (DV): The variable being measured (The "Effect"). Control vs. Experimental Group: The experimental group gets the "treatment"; the control group gets a placebo or nothing. Random Assignment: Every participant has an equal chance of being in either group. This prevents Bias. Single-Blind vs. Double-Blind: Single: Participants don't know which group they are in. Double: Neither the participants nor the researchers know. This prevents the researcher from accidentally giving "cues." WEEK 3: Biology and Behavior The "Hardware" section. How the physical brain creates the "Pink Slime" experience. 1. The Nervous System Map Central (CNS): Brain and Spinal Cord. Peripheral (PNS): Everything else. Somatic: Voluntary movements (walking). Autonomic: Involuntary (heartbeat). Sympathetic: "Fight or Flight" (Eyes dilate, heart speeds up, digestion stops). Parasympathetic: "Rest and Digest" (Calms the body down). 2. The Neuron (The Building Block) Dendrites: Receive messages. Soma (Cell Body): Process info. Axon: Sends the electrical signal. Myelin Sheath: Fatty tissue that speeds up the signal. Synapse: The tiny gap between neurons where chemicals travel. Neurotransmitters: Agonist: A chemical that mimics a neurotransmitter (enhances the effect). Antagonist: A chemical that blocks a neurotransmitter. 3. Brain Tools & Anatomy EEG: Measures electrical brain waves (good for sleep studies). MRI vs. fMRI: MRI shows structure (a picture); fMRI shows function (where blood is flowing). PET Scan: Uses radioactive "tracer" sugar to see which parts of the brain are active. The Endocrine System: Uses Hormones (slow-acting chemicals) released into the bloodstream by Glands (like the Adrenal or Pituitary). 4. The "Hidden" Biological Details (Week 3) Refractory Period: After a neuron fires, it needs a tiny "recharge" break before it can fire again. Think of it like a camera flash or a toilet flushing—you can't do it twice in a split second. Broca’s Area vs. Wernicke’s Area: * Broca’s: Controls Speech Production (Frontal Lobe). If damaged, you know what you want to say but can't get the words out. Wernicke’s: Controls Language Comprehension (Temporal Lobe). If damaged, you can speak, but it's "word salad"—it makes no sense. WEEK 4: Consciousness Consciousness is your awareness of yourself and your environment. It’s not an "on/off" switch; it’s a spectrum. 1. Processing Levels Conscious Processing: Tasks that require focused attention (e.g., learning a new TikTok dance or solving a math problem). Automatic Processing: Tasks we do "without thinking" once they are learned (e.g., walking or an experienced driver steering a car). 2. Altered States Hypnosis: A state of extreme self-suggestion where a person is highly open to direction. Meditation: A practice of focused attention to achieve mental clarity and emotional calm. Daydreaming: A shift in attention away from the current task toward internal thoughts and "mental movies." 3. Psychoactive Drugs (The "Drug Cabinet") Depressants (Alcohol, Barbiturates): Slow down the Central Nervous System (CNS). They decrease heart rate and reaction time. Stimulants (Caffeine, Nicotine, Cocaine, ADHD meds): Speed up the CNS. They increase heart rate and energy. Opiates (Heroin, Morphine, Vicodin): Specifically target pain receptors. They mimic Endorphins to stop pain and create euphoria. Hallucinogens (LSD, Marijuana, Psilocybin): Distort perceptions and evoke sensory images in the absence of sensory input. WEEK 5: Sleep and Dreams Sleep is a biological necessity, not a luxury. Your brain is incredibly active during this "downtime." 1. Stages of Sleep (The Cycle) Stage 1 (NREM-1): Light sleep. You might experience "hypnagogic sensations" (feeling like you are falling). Stage 2 (NREM-2): Deep relaxation. Characterized by Sleep Spindles (bursts of rapid brain activity). Stage 3 & 4 (NREM-3): Deepest sleep. This is when the body repairs itself. If you wake up here, you’ll feel very groggy. REM (Rapid Eye Movement): The "Dream Stage." Your brain waves look like you are awake, but your motor cortex is blocked—meaning your body is paralyzed so you don't act out your dreams. 2. Dream Theories (Why do we dream?) Freud’s Wish Fulfillment: Dreams are a "safety valve" for unacceptable feelings. Manifest Content: The actual storyline of the dream (e.g., being chased by a giant Pink Slime). Latent Content: The hidden psychological meaning (e.g., you are running away from your final exam stress). Activation-Synthesis: The brain's attempt to make sense of random neural static. The brain "synthesizes" a story from random "activation." Information Processing: Dreams help us sort out the day's events and consolidate memories. Threat Simulation Theory: Dreaming allows us to "practice" surviving dangerous situations in a safe environment. WEEK 6: Thinking and Processing This is about "Cognition"—how we use our "Pink Slime" to solve problems and make decisions. 1. Building Blocks of Thought Concepts: Mental groupings of similar objects (e.g., the concept of "Dogs"). Prototype: The best example of a category. (If I say "Bird," you probably think of a Robin, not a Penguin. The Robin is your prototype). Schemata (Schema): A mental framework that helps us organize and interpret information (e.g., your "School Schema" includes desks, teachers, and bells). 2. Problem-Solving Tactics Trial-and-Error: Trying random solutions until one works. (Slow and inefficient). Algorithms: A step-by-step, logical rule that guarantees a solution. (e.g., a math formula or checking every single aisle in a store to find milk). Heuristics: A mental shortcut or "rule of thumb." It's faster than an algorithm but can lead to errors. (e.g., looking at the signs above the aisles to find the milk). 3. The Biases (Why we make mistakes) Confirmation Bias: Searching for information that supports our preconceptions and ignoring everything else. Hindsight Bias: After an event occurs, believing we "knew it all along." Anchoring Bias: Getting "stuck" on the very first piece of information offered. (e.g., if a shirt is "on sale" for $50 down from $100, you think $50 is a deal, even if the shirt is only worth $10). Availability Heuristic: Estimating the likelihood of events based on how easily they come to mind. (e.g., being afraid of a plane crash because you saw one on the news, even though car crashes are more common). Mental Set: The tendency to approach a problem in one particular way, often a way that has worked in the past but may not work now. WEEK 7: Memory Memory is the persistence of learning over time. 1. The Three Stages of Memory Encoding: Getting information into our brain. Semantic Encoding: Encoding the meaning of words (Deepest processing). Visual Encoding: Encoding images. Acoustic Encoding: Encoding sounds. Storage: Retaining that information. Retrieval: Getting the information back out. 2. Types of Storage Short-Term Memory (STM): Holds about 7 items (plus or minus 2) for about 20 seconds. Long-Term Memory (LTM): Unlimited capacity and can last a lifetime. Explicit (Declarative): Facts and experiences (Semantic = facts; Episodic = your life stories). Implicit (Procedural): Skills (like riding a bike or typing). 3. Memory Sins & Failures Schacter’s Seven Sins: Includes Transience (fading over time), Absent-mindedness (forgetting your keys), and Persistence (unwanted memories that won't go away). Amnesia: Anterograde: You can't form new memories. Retrograde: You can't remember the past. 4. Enhancement Techniques Chunking: Organizing items into familiar, manageable units. Spaced Repetition: Studying small amounts over a long time rather than cramming. Mnemonic Devices: Memory aids like "PEMDAS" for math. 5. The "Subtle" Memory Sins (Week 7) The Serial Position Effect: You are most likely to remember the beginning of a list (Primacy Effect) and the end of a list (Recency Effect), but you’ll probably forget the middle. Pro-Tip: This is why you should study the "middle" weeks (Week 4, 5, 6) extra hard! Misinformation Effect: This is why eyewitness testimony is shaky. If someone asks, "How fast was the car going when it smashed into the pole?" you will remember the car going faster than if they said "hit." WEEK 8: Lifespan Development Developmental psychology examines how we change physically, cognitively, and socially from "womb to tomb." 1. Cognitive Development (Jean Piaget) Piaget believed children think differently than adults and move through four stages: Sensorimotor (0–2 years): Exploring the world through senses. Key milestone: Object Permanence (realizing things still exist even if you can't see them). Preoperational (2–7 years): Symbolic thought (make-believe) but lacks logic. Key trait: Egocentrism (thinking everyone sees the world exactly as they do). Concrete Operational (7–11 years): Logical thinking about physical objects. Key milestone: Conservation (understanding that volume stays the same even if the shape of the glass changes). Formal Operational (12+ years): Abstract reasoning and hypothetical "what if" thinking. 2. Psychosocial Development (Erik Erikson) Erikson focused on "crises" we face at each age. Trust vs. Mistrust (Infancy): Is the world safe? Identity vs. Role Confusion (Adolescence): "Who am I?" (This is the most common exam question). Integrity vs. Despair (Late Adulthood): Looking back on life with satisfaction or regret. 3. Moral Development (Lawrence Kohlberg) Pre-conventional: Doing the right thing to avoid punishment or get a reward. Conventional: Doing the right thing because it's the law or to fit in. Post-conventional: Doing the right thing based on universal ethical principles (even if it breaks the law). 4. Parenting Styles Authoritative: High warmth, high rules. (The "Goldilocks" style—best outcomes). Authoritarian: Low warmth, high rules. ("Because I said so!"). Permissive: High warmth, low rules. (More like a friend than a parent). Uninvolved: Low warmth, low rules. (Neglectful). WEEK 9: Learning Learning is a relatively permanent change in behavior due to experience. 1. Classical Conditioning (Ivan Pavlov) Learning by association (connecting two stimuli). Unconditioned Stimulus (UCS): The natural trigger (Food). Unconditioned Response (UCR): The natural reflex (Drooling for food). Neutral Stimulus (NS): A trigger that means nothing yet (A Bell). Conditioned Stimulus (CS): The bell after it has been paired with food. Conditioned Response (CR): Drooling for the bell alone. 2. Operant Conditioning (B.F. Skinner) Learning by consequences (Rewards and Punishments). Positive Reinforcement: Adding something good to increase behavior (A gold star for working). Negative Reinforcement: Removing something bad to increase behavior (The car stops beeping when you buckle your seatbelt). Positive Punishment: Adding something bad to stop behavior (A speeding ticket). Negative Punishment: Taking away something good to stop behavior (Taking away your phone). 3. Observational Learning (Albert Bandura) Learning by watching others. Famous study: The Bobo Doll Experiment, where kids imitated adults punching a doll. 4. The "Fine Print" of Learning (Week 9) Spontaneous Recovery: After a behavior has been "extinct" (gone away) for a while, it suddenly reappears out of nowhere. (Like Pavlov's dog suddenly drooling at a bell weeks after he stopped). Generalization vs. Discrimination: Generalization: Fearing all dogs because one bit you. Discrimination: Only fearing the specific dog that bit you. WEEK 10: Social Influences This is the study of how the "situation" and "group" overpower the individual. 1. The Stanford Prison Experiment (Zimbardo) Demonstrated the power of Social Roles and Scripts. Ordinary students became abusive "guards" or submissive "prisoners" simply because of the role they were assigned. 2. Influence & Conformity Normative Social Influence: Conforming to fit in and be liked (Dressing like your friends). Informational Social Influence: Conforming because you think the group has more info than you (Following the crowd in a new city). Obedience (Milgram): Following orders from an authority figure, even if it hurts someone else. 3. Group Dynamics Social Loafing: Working less hard in a group than when alone (The "Billy" effect). Deindividuation: Losing self-awareness and self-restraint in a large crowd or behind an anonymous screen. Group Polarization: When group discussion leads to more extreme opinions. Bystander Effect: People are less likely to help if others are around due to a Diffusion of Responsibility. 4. Thinking Patterns Fundamental Attribution Error: Blaming someone's personality for their behavior while ignoring the situation. Cognitive Dissonance: The "icky" feeling when our actions don't match our beliefs (e.g., you hate lying, but you just lied to your mom). We usually change our beliefs to match our actions to feel better. 5. Social Psych "Secret" Terms (Week 10) Self-Serving Bias: When we succeed, we take the credit ("I'm a genius"). When we fail, we blame the situation ("The test was unfair"). Foot-in-the-Door vs. Door-in-the-Face: Foot-in-the-Door: Ask for something tiny first, then the big thing. Door-in-the-Face: Ask for something HUGE (get rejected), then ask for the smaller thing you actually wanted. They are more likely to say yes because it feels like a "compromise." WEEK 11: Multiculturalism & Diversity This is the study of how culture, identity, and group values shape our behavior and how we interact with others. 1. Cultural Values Individualism: Cultures that value personal independence and "Me" goals (e.g., USA). Success is based on personal achievement. Collectivism: Cultures that value group harmony and "We" goals (e.g., Latin America, Asia). Success is based on doing what is best for the family or community. 2. Acculturation (How we adapt to new cultures) Integration: The "Best of Both Worlds." Keeping your original culture while participating in the new one. Assimilation: Giving up your original identity to fully "blend in" with the new culture. Separation: Keeping your original culture and avoiding the new one. Marginalization: Feeling like you don't belong to either culture (The "lonely" state). 3. Metaphors for Society The Melting Pot: The old idea that everyone should blend together and lose their differences to become one "American" identity. The Salad Bowl: The newer idea where cultures live together but stay distinct. You can see the "tomatoes" and the "lettuce"—everyone keeps their unique flavor. 4. Social Barriers Microaggressions: Small, daily slights or "backhanded compliments" toward marginalized groups (e.g., "You’re so articulate for someone from your neighborhood"). Prejudice vs. Discrimination: Prejudice is the thought/feeling (pre-judging), while Discrimination is the action (treating someone differently). WEEK 12: Stress & Health This is the study of how our brain's "appraisal" of the world affects our physical and mental health. 1. The Appraisal Process (Lazarus) Primary Appraisal: Judging if a stressor is a Threat (harmful) or a Challenge (potential for growth). Secondary Appraisal: Evaluating your tools. "Do I have the resources to handle this?" If yes, stress stays low. If no, panic sets in. 2. The Body’s Response (Selye’s GAS) General Adaptation Syndrome (GAS): The three stages of how your body reacts to stress: Alarm: Fight-or-Flight. Heart races, adrenaline hits. Resistance: Staying on "high alert" to cope. This is where you grind through the week. Exhaustion: Your battery dies. Your immune system crashes, and you get sick (The Cohen Cold Study). 3. Types of Stress Eustress: "Good stress." The kind that motivates you to finish a project or perform well in a game. Distress: "Bad stress." Chronic pressure that leads to burnout, fatigue, and health problems. 4. Coping Strategies Problem-Focused Coping: Attacking the problem directly. (Example: Time-Blocking your homework so it isn't overwhelming). Emotion-Focused Coping: Managing the feelings. (Example: Going to the Gym or meditating to stop feeling anxious). 5. Stress "Secret" Terms Cortisol: The primary stress hormone. Great for emergencies, but too much of it "eats" your memory and weakens your heart. Psychoneuroimmunology: The fancy word for the study of how your brain (stress) talks to your immune system. WEEK 13: Mental Wellness & The Science of Happiness The goal of this week is to identify the psychological frameworks and empirical studies that explain how humans build resilience and long-term well-being. 1. The Three Dimensions of Happiness (Module 14.5) According to the textbook, happiness is an enduring state consisting of joy and contentment. It is built through three "lives": The Pleasant Life: Attaining and savoring daily pleasures that add joy to the moment (e.g., the aroma of coffee or the feeling of sunshine). The Good Life: Identifying your unique skills and using them to enrich your life. This is where you find the state of Flow—being so "in the zone" that you lose track of time. The Meaningful Life: Using your talents and efforts in the service of the greater good or to help others, which provides a deeper sense of fulfillment than pleasure alone. 2. The Four Pillars of Well-Being (Wellness Studies) Based on Dr. Richard Davidson’s research, well-being is a "trainable skill" rather than a fixed trait. It is built on: Awareness: Noticing what your mind is doing in the present moment (meta-awareness). Connection: Cultivating kindness and healthy social relationships, which are the #1 predictor of long-term health. Insight: Having curiosity about how your own mind works and not believing every negative thought as a "fact." Purpose: Having a clear sense of direction or a "life compass" that guides your daily actions. 3. Empirical Evidence: The Creswell et al. Study (2014) This study provided scientific proof that mental training has biological effects: The Setup: An experimental design where students were randomly assigned to either a mindfulness group or an analytic control group. The Independent Variable: Brief 3-day mindfulness meditation training (25 mins/day). The Dependent Variable: Biological stress markers (Cortisol levels) and self-reported stress. The Result: The mindfulness group showed significantly lower cortisol levels, proving that meditation fosters biological resilience to stress. 4. Scientifically Proven Benefits of Gratitude Research shows that gratitude is a powerful "reset" for the nervous system: Physical: Improved sleep quality and duration; fewer reported aches and pains. Psychological: Reduces "toxic" emotions (envy, resentment) and increases mental strength. Studies of 9/11 survivors showed gratitude was a major factor in preventing PTSD. Social: Encourages "pro-social" behavior, making people more likely to form and maintain new relationships. 5. Mindfulness vs. Meditation (The State vs. The Practice) It is critical to distinguish between these two often-confused terms: Mindfulness: A state of being. It is the quality of being fully present, aware of where we are and what we’re doing, without being overly reactive or overwhelmed. Meditation: The formal practice or "mental gym" used to train the brain. It is the intentional time set aside to practice techniques that eventually lead to a consistent state of mindfulness. 6. Key Terminology & Cognitive Traps Affective Forecasting: The human tendency to overestimate how much future events (both good and bad) will affect our long-term happiness. We assume milestones like "perfect grades" will provide permanent joy, but they usually don't. Optimism & Resilience: Optimism is the general tendency to expect good outcomes. It is the "engine" of resilience—the ability to "bounce back" from major life stressors (like those listed on the SRRS). Problem-Focused vs. Emotion-Focused Coping: * Problem-Focused: Dealing with the stressor directly (e.g., studying for the test). Emotion-Focused: Managing the feelings associated with the stressor (e.g., taking a nap or exercising)
