Comprehensive Study Guide: Memory, Cognition, Development, Motivation, and Sexuality in Psychology

Ch. 6: Memory

Memory & the Brain

Memory involves the processes by which information is encoded, stored, and retrieved. Different brain regions contribute to various types of memory.

• Hippocampus: Essential for forming new long-term memories.

• Amygdala: Involved in emotional memories.

• Cerebellum: Important for procedural (implicit) memory.

• Prefrontal Cortex: Associated with working memory and decision-making.

Example: Damage to the hippocampus can result in an inability to form new explicit memories (anterograde amnesia).

Recognition vs. Recall

These are two primary methods of retrieving information from memory.

• Recognition: Identifying previously learned information from a list of options (e.g., multiple-choice questions).

• Recall: Retrieving information without cues (e.g., essay questions).

Example: Remembering a friend's phone number from memory (recall) vs. recognizing it in your contact list (recognition).

Constructive Processing

Memory is not a perfect recording; it is reconstructive and subject to alteration.

• Constructive Processing: The process by which memories are influenced by the meaning we give to events, expectations, and new information.

Example: Eyewitness testimony can be unreliable due to the reconstructive nature of memory.

Echoic vs. Iconic Memory

These are types of sensory memory that briefly hold information from the senses.

• Iconic Memory: Visual sensory memory, lasting less than a second.

• Echoic Memory: Auditory sensory memory, lasting 2-4 seconds.

Example: The ability to "see" an image for a brief moment after it disappears (iconic), or to recall the last few words spoken (echoic).

Various Types of Amnesia

Amnesia refers to memory loss caused by brain injury, disease, or psychological trauma.

• Anterograde Amnesia: Inability to form new memories after the onset of amnesia.

• Retrograde Amnesia: Loss of memories formed before the onset of amnesia.

• Dissociative Amnesia: Memory loss due to psychological factors, not physical injury.

Primacy vs. Recency Effect

These effects describe how the position of information in a sequence affects recall.

• Primacy Effect: Tendency to remember items at the beginning of a list.

• Recency Effect: Tendency to remember items at the end of a list.

Definition/Stages of Memory

Memory is typically divided into three stages:

• Encoding: Transforming sensory input into a form that can be stored.

• Storage: Maintaining encoded information over time.

• Retrieval: Accessing stored information when needed.

Types of Long-Term Memory

Long-term memory is divided into explicit (declarative) and implicit (non-declarative) memory.

• Explicit Memory: Conscious recall of facts and events.

  • Episodic Memory: Personal experiences and events.

  • Semantic Memory: General knowledge and facts.

• Implicit Memory: Unconscious memory for skills and procedures (e.g., riding a bike).

Types of Memory Interference

Interference occurs when information disrupts the retrieval of other information.

• Proactive Interference: Old information interferes with learning new information.

• Retroactive Interference: New information interferes with recalling old information.

Memory Cues & Techniques

Cues and strategies can enhance memory retrieval.

• Retrieval Cues: Stimuli that help access memories (e.g., context, state-dependent cues).

• Mnemonic Devices: Techniques like acronyms, visualization, and chunking to improve memory.

Example: Using "HOMES" to remember the Great Lakes (Huron, Ontario, Michigan, Erie, Superior).

Ch. 7: Cognition

Definition of Cognition

Cognition refers to the mental processes involved in acquiring, processing, and storing knowledge.

• Includes: Thinking, problem-solving, decision-making, and language.

Problem-Solving Strategies/Barriers

Problem-solving involves finding solutions to obstacles or challenges.

• Strategies: Algorithms (step-by-step procedures), heuristics (mental shortcuts), insight (sudden realization).

• Barriers: Functional fixedness, mental set, confirmation bias.

Example: Using a formula to solve a math problem (algorithm) vs. guessing based on experience (heuristic).

Measurements of Intelligence (IQ)

Intelligence is often measured using standardized tests that yield an Intelligence Quotient (IQ).

• IQ Formula: $IQ = \frac{\text{Mental Age}}{\text{Chronological Age}} \times 100$

• Modern Tests: Wechsler scales, Stanford-Binet test.

Sternberg’s Triarchic Theory

This theory proposes three types of intelligence:

• Analytical Intelligence: Problem-solving and academic skills.

• Creative Intelligence: Ability to deal with novel situations.

• Practical Intelligence: "Street smarts" or everyday tasks.

Definition of Intelligence

Intelligence is the capacity to learn from experience, solve problems, and adapt to new situations.

Validity vs. Reliability

These are key properties of psychological tests.

• Validity: The extent to which a test measures what it claims to measure.

• Reliability: The consistency of test results over time.

Special Populations

Refers to groups with unique cognitive or learning needs, such as individuals with intellectual disabilities or giftedness.

Levels of Concepts

Concepts are mental categories for grouping objects, events, or ideas.

• Superordinate Level: Broadest category (e.g., "animal").

• Basic Level: More specific (e.g., "dog").

• Subordinate Level: Most specific (e.g., "poodle").

Ch. 8: Development Across the Life Span

Types of Twins

Twin studies help distinguish genetic and environmental influences.

• Monozygotic (Identical) Twins: Develop from a single fertilized egg; genetically identical.

• Dizygotic (Fraternal) Twins: Develop from two separate eggs; genetically similar as siblings.

Parenting Styles

Parenting styles influence child development.

• Authoritarian: Strict, high demands, low responsiveness.

• Permissive: Few demands, high responsiveness.

• Authoritative: Balanced demands and responsiveness; considered most effective.

• Uninvolved: Low demands, low responsiveness.

Nature vs. Nurture

This debate concerns the relative influence of genetics (nature) and environment (nurture) on development.

Temperament Types

Temperament refers to innate personality traits.

• Easy: Regular, adaptable, and happy.

• Difficult: Irregular, non-adaptable, and irritable.

• Slow-to-Warm-Up: Low activity, somewhat negative, slow to adapt.

Styles of Attachment

Attachment styles describe the emotional bond between child and caregiver.

• Secure: Comfortable with caregiver, distressed when absent.

• Avoidant: Indifferent to caregiver's presence or absence.

• Ambivalent: Clingy, but resistant or angry when caregiver returns.

• Disorganized: Inconsistent, confused behavior.

Stages of Dying & Grief

Kübler-Ross identified five stages of grief:

• Denial

• Anger

• Bargaining

• Depression

• Acceptance

Stages of Prenatal Development

Prenatal development occurs in three stages:

• Germinal Stage: First two weeks after conception.

• Embryonic Stage: Weeks 2-8; major organs form.

• Fetal Stage: Week 9 to birth; growth and maturation.

Cognitive Development (Piaget)

Jean Piaget proposed four stages of cognitive development:

• Sensorimotor (0-2 yrs): Object permanence develops.

• Preoperational (2-7 yrs): Symbolic thinking, egocentrism.

• Concrete Operational (7-11 yrs): Logical thinking about concrete events.

• Formal Operational (12+ yrs): Abstract and hypothetical reasoning.

Developmental Research Designs

Methods for studying development over time:

• Longitudinal: Same individuals studied over a long period.

• Cross-sectional: Different age groups studied at one time.

• Cross-sequential: Combination of both methods.

Imaginary Audience/Personal Fable

Common cognitive distortions in adolescence:

• Imaginary Audience: Belief that others are constantly watching and judging.

• Personal Fable: Belief in one's uniqueness and invulnerability.

Psychosocial Development (Erikson)

Erik Erikson proposed eight stages of psychosocial development, each with a central conflict (e.g., trust vs. mistrust, identity vs. role confusion).

Ch. 9: Motivation and Emotion

Intrinsic & Extrinsic Motivation

Motivation can originate from within or from external sources.

• Intrinsic Motivation: Driven by internal rewards (e.g., enjoyment, satisfaction).

• Extrinsic Motivation: Driven by external rewards (e.g., money, praise).

Types of Psychological Needs

Humans have basic psychological needs, such as autonomy, competence, and relatedness (Self-Determination Theory).

Maslow’s Hierarchy of Needs

Abraham Maslow proposed a hierarchy of human needs, often depicted as a pyramid:

• Physiological Needs

• Safety Needs

• Love and Belonging

• Esteem

• Self-Actualization

Needs/Drives/Homeostasis

Motivation is influenced by physiological drives and the body's tendency to maintain homeostasis (balance).

• Drive-Reduction Theory: Motivation arises from the need to reduce internal tension caused by unmet needs.

• Homeostasis: The body's process of maintaining a stable internal environment.

Display Rules (Emotions)

Display rules are cultural norms that dictate how and when emotions can be expressed.

Elements of Emotions

Emotions consist of three components:

• Physiological arousal

• Expressive behaviors

• Conscious experience

Theories of Emotion

Major theories include:

• James-Lange Theory: Emotions result from physiological arousal.

• Cannon-Bard Theory: Arousal and emotion occur simultaneously.

• Schachter-Singer (Two-Factor) Theory: Emotion is based on arousal and cognitive labeling.

Ch. 10: Sexuality & Gender

Sex & Gender Concepts

Sex refers to biological differences (chromosomes, hormones, anatomy), while gender refers to social and psychological roles, behaviors, and identity.

Sexual Orientations

Sexual orientation describes patterns of romantic or sexual attraction (e.g., heterosexual, homosexual, bisexual, asexual).

Sexual Dysfunctions

Sexual dysfunctions are problems that interfere with sexual response or pleasure (e.g., erectile disorder, female orgasmic disorder).

Human Sexuality Research

Research in human sexuality includes studies by Alfred Kinsey, Masters and Johnson, and others, focusing on sexual behavior, attitudes, and physiology.

Primary/Secondary Sex Traits

• Primary Sex Traits: Structures directly involved in reproduction (e.g., ovaries, testes).

• Secondary Sex Traits: Features that emerge during puberty (e.g., breast development, facial hair).

Human Sexual Response Cycle

Masters and Johnson described four stages:

• Excitement

• Plateau

• Orgasm

• Resolution

Sexually-Transmitted Infections (STIs)

STIs are diseases transmitted through sexual contact (e.g., HIV/AIDS, chlamydia, gonorrhea, herpes).
