Lesson 4.3: Reducing Front-End Loads

Philosophy Exam 1 ⸻ Sigmund Freud (Psychoanalysis) 1. Id – Ego – Superego Freud explains personality as a system of three interacting structures that are in constant conflict. * Id The id is entirely unconscious and represents instinctual drives such as aggression, hunger, and sexual desire. It operates on the pleasure principle, meaning it demands immediate satisfaction without considering reality, morality, or consequences. It is irrational and purely driven by biological impulses. * Ego The ego develops to mediate between the id and external reality. It operates on the reality principle, meaning it tries to satisfy instinctual desires in realistic and socially acceptable ways. It uses reasoning, planning, and delayed gratification. It is partly conscious and responsible for decision-making. * Superego The superego represents internalized moral values and social rules learned from parents and society. It judges behaviour and produces feelings of guilt or pride depending on whether actions align with moral standards. It often conflicts with the id by imposing strict moral constraints. Key idea: personality results from the continuous tension between instinct (id), reality (ego), and morality (superego). ⸻ 2. Defence Mechanisms Defence mechanisms are unconscious psychological strategies used by the ego to reduce anxiety caused by conflict between the id, superego, and reality. They distort perception in order to protect the individual from psychological discomfort. * Repression Unacceptable thoughts or memories are pushed into the unconscious and become inaccessible, although they may still influence behaviour indirectly. * Denial The individual refuses to accept a painful or threatening reality. * Projection The person attributes their own unacceptable feelings or impulses to others. * Displacement Emotional impulses are redirected from the original source to a safer target. * Rationalization The individual creates false but logical explanations for behaviour in order to avoid guilt or anxiety. * Reaction Formation An unacceptable impulse is transformed into its opposite behaviour. * Regression Under stress, the individual returns to earlier, more childish patterns of behaviour. * Sublimation Unacceptable impulses are transformed into socially acceptable or productive activities. * Intellectualization Emotional situations are dealt with through abstract or logical thinking to avoid confronting feelings. * Compensation The individual develops strengths in one area to make up for weaknesses in another. * Identification The person adopts the traits or behaviours of another individual to reduce anxiety or increase self-esteem. * Undoing The person attempts to symbolically cancel out unacceptable thoughts or actions through corrective behaviour. Key idea: defence mechanisms are automatic, unconscious, and protect the ego by distorting reality. ⸻ 3. Psychosexual Stages Freud argues that personality develops through stages where psychic energy (libido) is focused on different parts of the body. Fixation at a stage can influence adult personality. * Oral stage (0–1): pleasure through feeding; fixation may lead to dependence or oral habits. * Anal stage (1–3): focus on control and toilet training; fixation may lead to orderliness or messiness. * Phallic stage (3–6): development of gender identity and early moral awareness; family dynamics are central. * Latency stage (6–puberty): sexual energy is dormant; focus on learning and social development. * Genital stage (puberty onward): mature sexuality and adult relationships. Key idea: early childhood experiences strongly shape adult personality. ⸻ René Descartes 1. Dualism Descartes argues that reality is composed of two fundamentally different substances: * Mind (res cogitans): non-physical substance responsible for thinking, consciousness, reasoning, and doubt. * Body (res extensa): physical substance that occupies space and follows mechanical laws. Although distinct, mind and body interact, creating the mind–body problem of how two different substances can influence each other. Key idea: humans are composed of both mental and physical substances that are fundamentally different. ⸻ 2. Rationalism Rationalism is the view that reason is the primary source of knowledge, more reliable than sensory experience. Descartes argues that the senses can deceive us through illusions and dreams, so knowledge must be based on clear and distinct ideas produced by reason. He uses methodic doubt, systematically doubting all uncertain beliefs until reaching something absolutely certain. Key idea: reliable knowledge must come from reason rather than the senses. ⸻ 3. Cogito: “I think therefore I am” Descartes establishes that even radical doubt proves existence. If he is doubting, he must be thinking; if he is thinking, he must exist as a thinking being. Key idea: the act of thinking guarantees the existence of the self. ⸻ Plato 1. Ideal Society Plato’s political philosophy divides society into three classes corresponding to parts of the human soul: * Rulers (philosopher-kings): guided by reason and wisdom; they govern society. * Guardians: guided by courage; they protect and defend the state. * Producers: guided by desire; they provide material goods and services. Justice occurs when each class performs its proper function without interfering in the roles of others. Key idea: social justice is harmony through specialization and proper role distribution. ⸻ 2. Theory of Forms Plato distinguishes between two levels of reality: * The physical world: constantly changing, imperfect, and perceived through the senses. * The world of Forms: eternal, perfect, and unchanging essences such as Beauty, Justice, and Equality. Physical objects are imperfect copies of these perfect Forms. Key idea: true knowledge is knowledge of eternal Forms, not sensory appearances. ⸻ 3. Allegory of the Cave Plato describes prisoners chained in a cave who see only shadows and believe them to be reality. One prisoner escapes and discovers the real world illuminated by the sun, which represents truth. When he returns, the others reject him. Key idea: education is the process of moving from illusion to truth, which is difficult and often resisted. ⸻ Francis Bacon 1. Four Idols of the Mind Bacon identifies four sources of systematic error in human thinking: * Idols of the Tribe: universal human biases in perception and reasoning. * Idols of the Cave: individual biases shaped by personal experience and education. * Idols of the Marketplace: errors caused by language and communication. * Idols of the Theatre: blind acceptance of philosophical systems and traditions. Key idea: human reasoning is naturally flawed and must be corrected through scientific method. ⸻ 2. Empiricism Empiricism is the theory that knowledge comes from sensory experience and observation. Bacon argues that scientific knowledge must be based on experimentation, data collection, and systematic observation rather than pure reasoning. Key idea: knowledge is grounded in experience, not abstract speculation. ⸻ 3. Induction vs Deduction Induction is reasoning from specific observations to general laws. Deduction is reasoning from general principles to specific conclusions. Bacon emphasizes induction as the foundation of scientific knowledge because it is based on empirical evidence. Key idea: science progresses by building general laws from observed facts. ⸻ Friedrich Nietzsche 1. “God is Dead” Nietzsche argues that modern science and secular thinking have undermined the authority of traditional religion as a source of meaning and morality. This leads to a cultural crisis in which old values collapse without being replaced. Key idea: the loss of religious authority creates a crisis of meaning. ⸻ 2. Nihilism Passive nihilism refers to despair and the belief that life has no meaning. Active nihilism refers to the rejection of old values in order to create new ones. Key idea: nihilism represents both the breakdown of meaning and the possibility of creating new values. ⸻ 3. Übermensch The Übermensch is the ideal individual who creates their own values, rejects conformity, embraces life fully, and overcomes traditional moral systems. Key idea: humans must move beyond inherited values and become creators of meaning. ⸻ Charles Darwin 1. Natural Selection Evolution occurs through natural selection. Individuals within a species vary, and those with advantageous traits are more likely to survive and reproduce. Over time, these traits become more common in the population. Key idea: evolution is driven by survival advantage rather than purposeful design. ⸻ 2. Morality (Evolutionary view) Darwin argues that morality is not divine but evolved through natural processes. Humans developed social instincts such as empathy and cooperation because these traits improved survival within groups. Key idea: morality is a product of biological and social evolution

Reagan's Reduction of Big Government - key facts

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

Key Principles of Organic Synthesis - Oxidation and Reduction

PRE-IB Chemistry Notes (based on your test) 1. Molecular Formula English A molecular formula shows the actual number of atoms in a molecule. Example: * H₂O = 2 hydrogen atoms and 1 oxygen atom * C₆H₁₂O₆ = 6 carbon, 12 hydrogen, 6 oxygen Important * Molecular formula = actual number * Empirical formula = simplest ratio Example: * Molecular formula: C₆H₁₂O₆ * Empirical formula: CH₂O Test question “What information does the molecular formula provide?” Correct answer: ✅ The actual numbers of atoms in a molecule ⸻ Русский Молекулярная формула показывает настоящее количество атомов в молекуле. Пример: * H₂O = 2 атома водорода и 1 атом кислорода * C₆H₁₂O₆ = 6 углеродов, 12 водородов, 6 кислородов Важно * Molecular formula = настоящее количество * Empirical formula = простое соотношение ⸻ 2. Isotopes English Isotopes are atoms of the same element with: * same number of protons * different number of neutrons Example: * Carbon-12 * Carbon-14 Both have: * 6 protons But different neutrons. Formula Neutrons = mass number − atomic number ⸻ Русский Изотопы — это атомы одного элемента: * одинаковое количество протонов * разное количество нейтронов Формула: Нейтроны = массовое число − атомный номер ⸻ 3. Protons, Neutrons and Electrons English Proton number = atomic number Electron number Neutral atom: electrons = protons Ion: * positive ion → lost electrons * negative ion → gained electrons Example ^{43}_{20}Ca^{2+} * protons = 20 * neutrons = 43 − 20 = 23 * electrons = 20 − 2 = 18 ⸻ Русский Протоны = атомный номер Электроны У нейтрального атома: электроны = протоны Ион: * плюс → потерял электроны * минус → получил электроны Пример: Ca²⁺: * 20 протонов * 23 нейтрона * 18 электронов ⸻ 4. Electron Configuration English Electrons fill shells. Rules * 1st shell = 2 electrons * 2nd shell = 8 * 3rd shell = 8 Examples Mg (12): 2,8,2 Cl (17): 2,8,7 Al (13): 2,8,3 Outer shell electrons Mg → 2 Cl → 7 ⸻ Русский Электроны распределяются по оболочкам. Примеры: * Mg = 2,8,2 * Cl = 2,8,7 * Al = 2,8,3 Внешние электроны: * Mg → 2 * Cl → 7 ⸻ 5. Ionic Bonding English Ionic bonding happens when electrons are transferred. * metals lose electrons * non-metals gain electrons Example: Mg + Cl Mg loses 2 electrons. Each chlorine gains 1. Formula: MgCl₂ ⸻ Русский Ионная связь появляется, когда электроны переходят от одного атома к другому. * металл теряет электроны * неметалл получает Пример: MgCl₂ ⸻ 6. Relative Atomic Mass and Relative Formula Mass English Relative Atomic Mass (Ar) Average mass of atoms compared with carbon-12. Example: Cl = 35.5 Relative Formula Mass (Mr) Total of all atomic masses in a formula. Example: H₂O = 2(1) + 16 = 18 ⸻ Русский Relative Atomic Mass Средняя масса атомов элемента. Relative Formula Mass Сумма всех атомных масс в формуле. Пример: H₂O = 18 ⸻ 7. Moles English Formula triangle n=\frac{m}{M} n = moles m = mass M = molar mass Example NaCl: M = 23 + 35.5 = 58.5 If mass = 117 g 117 ÷ 58.5 = 2 mol ⸻ Русский Формула: n = m / M n — моли m — масса M — молярная масса ⸻ 8. Concentration English Formula: c=\frac{n}{V} c = concentration n = moles V = volume in dm³ Important 1000 cm³ = 1 dm³ ⸻ Русский Формула: c = n / V V обязательно в dm³ 1000 cm³ = 1 dm³ ⸻ 9. Acids and Alkalis English Acid Produces H⁺ ions Alkali Produces OH⁻ ions Examples: * HCl = acid * NaOH = alkali ⸻ Русский Кислота выделяет H⁺ Щёлочь выделяет OH⁻ ⸻ 10. Strong and Weak Acids English Strong acid Fully ionizes in water. Example: HCl Weak acid Partially ionizes. Example: CH₃COOH Important Strong ≠ concentrated ⸻ Русский Сильная кислота полностью распадается. Слабая — только частично. ⸻ 11. Amphoteric Compounds English Amphoteric substances can act as: * acid * base Example: Al₂O₃ ⸻ Русский Амфотерные вещества могут быть: * кислотой * основанием ⸻ 12. pH and Indicators English pH scale * below 7 = acid * 7 = neutral * above 7 = alkali Indicators Litmus: * acid → red * alkali → blue Phenolphthalein: * acid → colorless * alkali → pink ⸻ Русский pH: * меньше 7 = кислота * 7 = нейтрально * больше 7 = щёлочь ⸻ 13. Acid-Base Titration English Titration is used to find concentration. Steps 1. Add indicator 2. Add acid/base slowly 3. Endpoint color change 4. Use formula Common indicators * phenolphthalein * methyl orange ⸻ Русский Титрование используют для нахождения концентрации. Шаги: 1. Добавить индикатор 2. Медленно добавлять раствор 3. Смотреть изменение цвета ⸻ 14. Redox Reactions English Oxidation Loss of electrons Reduction Gain of electrons OIL RIG: * Oxidation Is Loss * Reduction Is Gain ⸻ Русский Окисление = потеря электронов Восстановление = получение электронов ⸻ 15. Hydrophobic and Hydrophilic English Hydrophobic “Water-fearing” Does not mix with water. Example: oil Hydrophilic “Water-loving” Mixes with water. Example: salt ⸻ Русский Hydrophobic: не смешивается с водой Hydrophilic: смешивается с водой ⸻ 16. Organic Chemistry Naming (IMPORTANT FOR TEST) English Alkane Only single bonds General formula: C_nH_{2n+2} Alkene Contains double bond General formula: C_nH_{2n} Alkyne Contains triple bond General formula: C_nH_{2n-2} ⸻ Русский Алкан: только одинарные связи Алкен: двойная связь Алкин: тройная связь ⸻ 17. IUPAC Naming Quick Rules English Step 1 Find longest chain. Step 2 Count carbons: * meth = 1 * eth = 2 * prop = 3 * but = 4 * pent = 5 * hex = 6 Step 3 Find double bond. Step 4 Number chain from nearest double bond. Step 5 Name branches: * methyl * ethyl ⸻ Русский 1. Найти самую длинную цепь 2. Посчитать углероды 3. Найти двойную связь 4. Нумеровать с ближайшей двойной связи 5. Назвать ответвления ⸻ 18. Combustion English Combustion = burning in oxygen. Example: C_5H_{12}+8O_2\rightarrow5CO_2+6H_2O Products: * carbon dioxide * water ⸻ Русский Горение — реакция с кислородом. Продукты: * CO₂ * H₂O ⸻ 19. Activity Series English More reactive metals replace less reactive metals. Mg is more reactive than H: → reacts with acid Cu is less reactive than Fe: → cannot replace Fe ⸻ Русский Более активный металл вытесняет менее активный
