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

Chemistry chapter 4 Acids, bases and neutralisation

INTRODUCTORY SOCIOLOGY — CHAPTERS 1–5 The Study Guide Key concepts, theories, and methods for mastering the social world Ch. 1 — Sociology Ch. 2 — Research Ch. 3 — Culture Ch. 4 — Socialization Ch. 5 — Groups 01 CHAPTER ONE Sociology and the Real World What Is Sociology? Sociology is the systematic, scientific study of human society, social relationships, and social institutions. It examines how group membership and social forces shape individual behavior, beliefs, and life chances — using the sociological imagination (C. Wright Mills) to connect personal troubles to larger historical and structural forces. Micro vs. Macro Sociology micro Microsociology Focuses on small-scale, face-to-face interactions: how individuals communicate, negotiate meaning, and create social reality in everyday situations. Example: a conversation between two people. macro Macrosociology Focuses on large-scale social structures, institutions, and broad patterns across societies. Example: how capitalism shapes inequality across a nation. Major Theoretical Perspectives Structural Functionalism Society is a system of interrelated parts (institutions) that each serve a function to maintain stability and order. Dysfunction disrupts equilibrium. Key figures: Durkheim, Parsons. Conflict Theory Society is characterized by competition and inequality. Those with power exploit those without; social change comes through struggle. Key figure: Marx. Weberian Theory Emphasizes the role of ideas, culture, and meaning (not just economics) in shaping social life. Introduces stratification by class, status, and party; the concept of rationalization and bureaucracy. Key figure: Weber. Symbolic Interactionism People act based on the meanings they attach to objects and others, meanings that arise through social interaction and are maintained through interpretation. Key figures: Mead, Blumer. micro Postmodernism Rejects grand narratives and universal truths; argues that reality is socially constructed, knowledge is fragmented, and power shapes what counts as truth. Skeptical of science's neutrality. Key figures: Foucault, Baudrillard. Midrange Theory Seeks to build limited, testable theories about specific phenomena rather than sweeping explanations of all of society. Bridges abstract theory and empirical research. Key figure: Merton. 02 CHAPTER TWO Studying Social Life: Research Methods Quantitative vs. Qualitative Research Quantitative Uses numerical data and statistical analysis to test hypotheses and identify patterns across large samples. Examples: surveys with Likert scales, census data, experiments with control/treatment groups. Qualitative Generates rich, descriptive, non-numerical data to understand meaning, experience, and context in depth. Examples: ethnography, in-depth interviews, focus groups, content analysis of texts. Steps of the Scientific Method Identify a research problem or question Review existing literature on the topic Formulate a hypothesis (a testable prediction) Design a research methodology and collect data Analyze the data Draw conclusions and report findings (inviting replication) Six Research Methods — Strengths & Weaknesses Method Description Strengths Weaknesses Ethnography / Participant Observation Researcher immerses in a social setting to observe behavior firsthand Deep insight; captures context; reveals hidden norms Time-intensive; small scale; researcher bias; ethical issues of access Interviews Structured, semi-structured, or unstructured conversations to gather in-depth perspectives Rich qualitative detail; flexible; clarification possible Interviewer effect; social desirability bias; hard to generalize Surveys Standardized questionnaires administered to large samples Efficient; large-scale; quantifiable; cheap Superficial; question wording bias; low response rates; can't capture complexity Existing Sources Analysis of historical records, official statistics, media, documents, or prior studies Non-reactive; access to historical data; cost-effective Data may be incomplete, biased, or collected for other purposes Experiments Manipulates an independent variable in controlled conditions to measure effects Establishes causality; controls for confounds; replicable Artificial setting; ethical constraints; demand characteristics; limited scope Social Network Analysis Maps and measures relationships and information flows among individuals or groups Reveals structural patterns invisible in individual-level data; visual and quantitative Data collection is complex; boundary specification problems; privacy concerns Pitfalls & Ethical Issues Validity & Reliability: Ensuring a study measures what it claims to and produces consistent results Sampling Bias: Non-representative samples skew findings Researcher Bias: Personal values and assumptions can distort data collection and interpretation Informed Consent: Participants must voluntarily agree based on full knowledge of the study Confidentiality & Anonymity: Protecting the identities and privacy of participants Harm Prevention: Research must not expose participants to physical, psychological, or social harm Deception: Deceiving subjects (e.g., Milgram) raises serious ethical concerns even when scientifically useful 03 CHAPTER THREE Culture Defining Culture Culture is the totality of shared beliefs, values, norms, symbols, language, material objects, and practices that members of a society learn and transmit across generations. Ethnocentrism Judging another culture by the standards of one's own, viewing one's culture as superior. Can lead to misunderstanding and discrimination. Cultural Relativism Understanding a culture on its own terms, without imposing outside judgments. Promotes open-minded cross-cultural comparison. Components of Culture Symbols: Anything that carries shared meaning (flags, words, gestures) Language: The primary vehicle for transmitting culture; shapes perception (Sapir-Whorf hypothesis) Values: Broad, shared standards of what is good, desirable, or important Norms: Specific rules of behavior — folkways (informal), mores (moral norms), and laws (formalized) Material Culture: Physical objects created and used by a society (tools, buildings, clothing) Non-material Culture: Intangible elements — beliefs, values, ideas, customs Subcultures & Countercultures in the U.S. A subculture shares the dominant culture's overall values but maintains distinct norms or practices. A counterculture actively opposes or rejects core values of the dominant culture. Subcultures: LGBTQ+ communities Amish communities Hip-hop culture Gamer culture College Greek life Countercultures: 1960s hippie movement Militia movements Punk movement Anti-consumerism groups Processes of Cultural Change Discovery: Recognizing and understanding something previously unknown Invention: Creating new tools, ideas, or social patterns Diffusion: Spreading cultural elements from one culture to another Cultural Imperialism: Dominant cultures overpower or displace local ones (often via media or globalization) Acculturation: A minority group adopts elements of a dominant culture 04 CHAPTER FOUR Socialization, Interaction, and the Self Nature vs. Nurture Human behavior is shaped by both genetics (biological predispositions, temperament) and social environment (culture, interaction, learning). Sociologists emphasize that even traits with biological bases are expressed and interpreted through social contexts. Studies of feral children and cases of extreme isolation demonstrate that human potential requires social interaction to develop. Socialization & Social Isolation Socialization is the lifelong process by which individuals learn the norms, values, behaviors, and social skills appropriate to their society. Cases of social isolation (e.g., children raised in severely deprived environments) show that without social contact, children fail to develop language, emotional regulation, and basic cognitive skills — demonstrating that the "self" is fundamentally social in origin. Theories of the Self Cooley — "Looking-Glass Self" We develop our self-concept by imagining how others perceive us, then internalizing those imagined judgments. The self is a reflection of social feedback. Mead — "I" and "Me" The self has two parts: the spontaneous I and the socialized Me. Through play and games, children learn to take on the role of others and internalize the "generalized other" (society's expectations). Goffman — Dramaturgical Model Social life is like a theatrical performance. We manage impressions in "front stage" behavior and relax norms "backstage." The self is a performance, not a fixed essence. Agents of Socialization Family: The primary agent; instills foundational values, language, and identity from birth Schools: Teach not only academic skills but the "hidden curriculum" — punctuality, obedience, competition Peer Groups: Increasingly important in adolescence; shape attitudes, norms, and sense of belonging outside family Media: Pervasive shaper of cultural norms, gender roles, beauty standards, and political attitudes Statuses, Roles, and Role Conflict Ascribed status: Assigned at birth, involuntary (race, sex, birth order) Achieved status: Earned through effort or choice (occupation, education) Master status: One status that overrides all others (e.g., felon, celebrity) Role conflict: Occurs when incompatible demands arise from two different statuses (e.g., parent vs. employee) Role strain: Tension within a single role when its demands are contradictory (e.g., a manager who must be both friend and disciplinarian) 05 CHAPTER FIVE Separate and Together: Life in Groups Primary vs. Secondary Groups Primary Groups Small, intimate, emotionally close groups with enduring relationships. Members value the relationship for its own sake. Examples: family, close friends, a tight-knit sports team. Secondary Groups Larger, more impersonal, and goal-oriented. Relationships are instrumental. Examples: a workplace, a university class, a professional association. Group Size, Cohesion, Prejudice & Discrimination Dyads (2 people): Most intimate but fragile — collapses if one leaves Triads (3 people): More stable; coalitions can form; a third party can mediate or divide Larger groups: Greater stability but less intimacy; formalization of rules becomes necessary Cohesion: High cohesion strengthens commitment and performance but can lead to groupthink In-groups & Out-groups: Defining "us" vs. "them" fuels prejudice (negative attitudes) and discrimination (unequal treatment) against out-group members Social Influence & Conformity — Three Classic Experiments Asch Conformity Studies (1950s) Participants gave obviously wrong answers on a line-comparison task when confederates unanimously did so first — showing powerful pressure to conform even when the correct answer was clear. Milgram Obedience Studies (1960s) Participants administered what they believed to be dangerous electric shocks on an authority figure's orders — revealing alarming levels of obedience to legitimate authority. Zimbardo Stanford Prison Experiment (1971) College students assigned roles of "guard" or "prisoner" quickly conformed to those roles so intensely the study had to be stopped — illustrating how situational context shapes behavior. Group Composition & Leadership Diversity: Diverse groups tend to produce more creative solutions but can experience more conflict initially Leadership styles: Authoritarian (top-down, efficient in crisis); Democratic (collaborative, higher satisfaction); Laissez-faire (minimal direction, works with highly self-motivated groups) Instrumental leaders focus on task completion; expressive leaders maintain group morale and cohesion Bureaucracy & McDonaldization Bureaucracy (Weber) is a formal organization characterized by a clear hierarchy of authority, written rules and procedures, specialization of labor, and impersonality. It is the dominant organizational form of modern society. McDonaldization (Ritzer) extends Weber's rationalization thesis: modern society increasingly organizes social life around four principles modeled on fast food — efficiency (the optimal method), calculability (emphasis on quantity over quality), predictability (standardized outcomes), and control (substituting technology for human judgment). The irony: the rational system produces irrational outcomes (e.g., dehumanization, loss of creativity, homogenization of culture)
