Source Amnesia: Forgetting who told you something or where you heard it.
Misinformation Effect: Memory distortion caused by misleading suggestions (e.g., "lost in the mall" experiment).
Framing: The way a question is posed influences memory recall (e.g., "how fast were the cars going when they smashed?").
Imagination Inflation: Increased confidence that an event occurred after imagining it, even if it never happened.
Types of Amnesia
Anterograde Amnesia: Inability to form new memories (e.g., "50 First Dates").
Retrograde Amnesia: Loss of memories prior to the amnesia event.
Intelligence & Achievement
Intelligence Theories:
Single Intelligence (g Factor): A general intelligence (g) underlies all mental skills (typical of IQ tests).
Multiple Intelligences: Suggests intelligence includes various types beyond math/language.
First IQ Test Formula:
IQ = \frac{\text{mental age}}{\text{chronological age}} \times 100
Mental Age: Age level at which a person performs (compared to others of the same age).
Standard IQ Scores: 100 is average, with a standard deviation (SD) of 15.
Psychometrics in Testing
Standardization: Consistent testing conditions and grading procedures (e.g., SAT, AP exams).
Reliability: Tests must yield consistent results over time. Methods include:
Split-Half Reliability: Comparing scores between two halves of a test.
Test-Retest Reliability: Administering the same test at different times.
Validity: Tests must accurately measure intended concepts.
Construct Validity: Test must measure the intended construct (e.g., IQ tests should measure IQ).
Predictive Validity: Ability to accurately predict traits (e.g., high math scores predict engineering success).
Types of Tests
Aptitude Tests: Assess potential to learn new skills (e.g., ASVAB).
Achievement Tests: Assess knowledge in specific subjects (e.g., AP tests).
Historical Issues with Intelligence Testing
Nature vs. Nurture: Role of genetics and environment in influencing IQ.
MZ twins tend to have similar IQs; adopted children align more with biological parents.
Environmental factors, like schooling, significantly influence IQ.
Socioeconomic factors, such as poverty, also affect test scores.
Eugenics: Historical attempts to improve the gene pool through controlling reproduction.
Culture Fair Tests: Aim to minimize cultural bias by focusing on non-language skills.
Stereotype Threat & Lift: Anxiety over fulfilling negative stereotypes affects performance, while comparing oneself to negatively stereotyped groups can enhance performance.
Flynn Effect: Rising IQ scores over the last 80 years attributed to improved education and healthcare.
Mindsets:
Fixed Mindset: Belief that intelligence is static, leading to reduced effort.
Growth Mindset: Belief that intelligence can develop over time, encouraging more effort.
Developmental Psychology
Thematic Issues in Development
Nature vs. Nurture: Focus on genetic vs. environmental influences.
Continuous vs. Discontinuous: Whether development occurs gradually or in stages (e.g., Piaget’s stages).
Stability vs. Change: Whether traits persist or change through life.
Research Methods
Cross-Sectional Studies: Examine different age groups at one time; quick but shows generational gaps.
Longitudinal Studies: Follow the same individuals over time; rich data but expensive and with high dropout rates.
Physical & Cognitive Development
Prenatal Development: Influenced by teratogens (e.g., drugs, alcohol).
Maturation: Natural progression in physical development, with gross motor skills (e.g., walking) developing before fine skills (e.g., writing).
Object Permanence: Understanding that objects continue to exist even when not visible.
Piaget’s Stages of Cognitive Development:
Sensorimotor Stage (0-2 yrs): Exploration and lacking object permanence.
Pre-operational Stage (2-7 yrs): Use of symbols, egocentrism, and lack of conservation.
Concrete Operational Stage (7-11 yrs): Logical thinking about concrete events.
Emphasizes social interaction in cognitive development and the Zone of Proximal Development (ZPD), where learning lies between what a learner can do alone and with help.
Crystallized Intelligence: Knowledge from past experiences increases with age.
Fluid Intelligence: The ability to solve new problems decreases with age.
Language Development
Phonemes: Smallest sound units (e.g., "ch").
Morphemes: Smallest units with meaning (e.g., "-ed").
Stages of language acquisition:
Cooing: vowel sounds.
Babbling: phonemes with consonants.
One-word stage: Basic wants.
Two-word stage (telegraphic speech): More advanced communication.
Socioemotional Development
Temperament: Patterns of emotional response in infants influence attachment styles (e.g., easy, difficult, slow to warm).
Attachment Styles:
Secure: Upset when parent leaves but calmed upon return.
Insecure: Avoidant, anxious, or disorganized behaviors.
Parenting Styles: Influence child development:
Authoritarian: High demands, low responsiveness.
Permissive: Low demands, high responsiveness.
Authoritative: Balanced approach; promotes social competence.
Erikson’s Stages of Socioemotional Development
Trust vs. Mistrust: (0-18 months) Basic trust formed.
Autonomy vs. Shame & Doubt: (1-3 yrs); promoting independence.
Initiative vs. Guilt: (3-6 yrs); learning initiative and creativity.
Industry vs. Inferiority: (6-puberty). Accomplishing tasks leads to competence.
Identity vs. Role Confusion: (adolescence-20s); developing self-identity.
Intimacy vs. Isolation: (20s-40s); forming close relationships.
Generativity vs. Stagnation: (40s-60s); contributing to society.
Integrity vs. Despair: (60s+); reflecting on life achievements.
Identity Development (Marlowe's Theory)
Identity Diffusion: Lack of commitment and exploration.
Foreclosure: Commitment without exploration.
Moratorium: Active exploration without commitment.
Identity Achievement: Commitment after exploration.
Motivation Theories
Instinct Theory: Motivation driven by innate patterns and response to stimuli (e.g., mating behaviors).
