Overview

This study guide covers key psychological and physiological concepts from Chapters 5 through 8 of the required textbook. It is designed to help students prepare for exam questions by providing detailed explanations, definitions, and examples of major topics, including memory, emotion, motivation, learning, and intelligence.

Memory and Emotion

Physiological and Psychological Components of Emotion

• Emotion involves both physiological changes (such as increased heart rate, sweating) and psychological interpretation.

• The sympathetic nervous system is responsible for the physiological arousal associated with emotions like fear or excitement.

• Example: Feeling your heart race and palms sweat when scared is due to sympathetic nervous system activation.

Memory: Reliability and Reconstruction

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

• Both emotion, suggestion, and belief can influence memory accuracy.

• Recovered and false memories can feel equally real and emotionally powerful.

• There is no reliable way to distinguish true from false memories without corroborating evidence.

• Example: Cognitive psychologist Elizabeth Loftus demonstrated that memory can be altered by suggestion.

Motivation and Theories of Motivation

Leptin and Biological Regulation

• Leptin is a hormone produced by fat (adipose) cells and released into the bloodstream.

• It plays a key role in regulating hunger, body weight, and energy balance.

• Leptin signals the brain to reduce hunger and increase energy expenditure when fat stores are sufficient.

Humanistic Theories of Motivation

• Emphasize personal growth, self-concept, and intrinsic motivation.

• Dr. Ashley’s focus on self-actualization and realization of potential aligns with humanistic perspectives.

Social and Cultural Influences on Memory

• Cultural values and socialization practices affect what is remembered and how memories are stored.

• People from individualistic cultures (e.g., U.S., Western nations) tend to recall personal, unique experiences.

• People from collectivist cultures recall social or family-oriented experiences.

Intelligence and Problem Solving

Sternberg’s Triarchic Theory of Intelligence

• Psychologist Robert Sternberg proposed that intelligence consists of three types:

  • Analytical (problem-solving abilities)

  • Creative (ability to deal with new situations)

  • Practical (everyday tasks and social skills)

• This theory expands intelligence beyond traditional IQ tests.

Correlation vs. Causation

• Correlation means two variables are related, but does not imply one causes the other.

• Understanding this distinction is crucial when interpreting research findings.

Problem Solving and Flexibility

• Effective problem solving requires flexibility and the ability to view situations from multiple perspectives.

• Obstacles include functional fixedness (seeing objects only in their usual function), mental set, and confirmation bias.

• Insight is a sudden realization of a solution without a step-by-step strategy.

Learning and Conditioning

Operant Conditioning

• Reinforcement is any event or stimulus that increases the likelihood of a behavior being repeated.

• Reinforcement can be positive (adding something pleasant) or negative (removing something unpleasant).

• Punishment is a consequence that decreases the likelihood of a behavior being repeated.

• Schedules of reinforcement (e.g., fixed ratio, variable interval) affect how quickly and strongly learning occurs.

Classical Conditioning

• Learning occurs when a neutral stimulus becomes associated with a meaningful stimulus, eliciting a similar response.

• Key factors: frequency of pairing, timing, intensity, and biological predispositions.

Emotion Theories

James-Lange Theory of Emotion

• States that emotion results from interpreting physiological changes in the body.

• Example: You feel afraid because you notice your heart pounding and muscles tense.

Cognitive Appraisal Theory of Emotion

• Proposes that our interpretation or appraisal of a situation determines the emotion we experience.

• Emotion is not just physiological; it depends on how we evaluate and think about events.

Motivation: Characteristics and Processes

Three Characteristics of Motivation

1. Activation: Initiation or production of behavior (e.g., deciding to go for a run).

2. Persistence: Continued effort toward a goal despite obstacles (e.g., studying for hours).

3. Intensity: Strength or vigor of motivation (e.g., working harder for a desired outcome).

Processes Necessary for Imitation of Behavior

• Attention

• Retention

• Motor reproduction

• Motivation

Biological Regulation of Eating

Short-Term and Long-Term Signals

• Short-term signals: Stomach contractions (hunger pangs), blood glucose levels, hormones (insulin, cholecystokinin).

• Long-term signals: Leptin levels, overall energy balance, and body weight regulation.

• Brain centers: The hypothalamus (lateral and ventromedial nuclei) regulates hunger and satiety.

Intelligence Testing

Stanford-Binet Intelligence Scale and IQ

• Lewis Terman revised the Binet-Simon intelligence test, creating the Stanford-Binet Intelligence Scale.

• IQ (Intelligence Quotient) is calculated as:

• IQ is a numerical measure of intelligence.

Heuristics and Decision Making

• Heuristics are mental shortcuts that help make decisions under uncertainty but can lead to systematic biases and errors.

• Availability heuristic: Judging the likelihood of an event based on how easily examples come to mind.

• Representativeness heuristic: Judging based on similarity to a prototype or stereotype.
