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

Learning Theories

Classical Conditioning

Classical conditioning is a type of associative learning where a neutral stimulus becomes associated with a meaningful stimulus, eliciting a similar response.

• Unconditioned Stimulus (US): A stimulus that naturally and automatically triggers a response (e.g., food causing salivation).

• Unconditioned Response (UR): The unlearned, naturally occurring response to the unconditioned stimulus (e.g., salivation to food).

• Conditioned Stimulus (CS): A previously neutral stimulus that, after association with the US, triggers a conditioned response (e.g., bell after pairing with food).

• Conditioned Response (CR): The learned response to the previously neutral stimulus (e.g., salivation to bell).

• Acquisition: The initial stage when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response.

• Extinction: The diminishing of a conditioned response when the US no longer follows the CS.

• Spontaneous Recovery: The reappearance of a weakened CR after a pause.

• Generalization: The tendency to respond in the same way to stimuli similar to the CS.

• Discrimination: The learned ability to distinguish between a CS and other irrelevant stimuli.

Example: Pavlov's dogs salivating to a bell after repeated pairings with food.

Operant Conditioning

Operant conditioning involves learning through consequences, where behaviors are strengthened or weakened by reinforcement or punishment.

• Reinforcement: Increases the likelihood of a behavior.

• Punishment: Decreases the likelihood of a behavior.

• Positive: Adding a stimulus (e.g., giving a reward or adding a chore).

• Negative: Removing a stimulus (e.g., taking away a privilege or removing discomfort).

• Primary Reinforcers: Innately satisfying (e.g., food, water).

• Secondary Reinforcers: Learned value (e.g., money, praise).

• Schedules of Reinforcement: Patterns that define how often a behavior is reinforced (e.g., fixed-ratio, variable-ratio, fixed-interval, variable-interval).

Example: Giving a child candy for completing homework (positive reinforcement).

Observational Learning

Observational learning occurs by watching and imitating others, rather than through direct experience.

• Four Parts of the Process:

  1. Attention

  2. Retention

  3. Reproduction

  4. Motivation

• Model Characteristics: Models are more likely to be imitated if they are perceived as similar, attractive, or successful.

• Mirror Neurons: Neurons that fire both when performing an action and when observing the same action performed by another, facilitating imitation and empathy.

Example: A child learns to tie shoes by watching a parent.

Memory Processes

Encoding, Storage, and Retrieval

Memory involves three key processes: encoding (input), storage (maintenance), and retrieval (output).

• Encoding: Transforming information into a form that can be stored in memory.

• Storage: Maintaining encoded information over time.

• Retrieval: Accessing stored information when needed.

• Improvement Strategies: Rehearsal, elaboration, organization, and use of mnemonic devices.

Example: Studying for an exam by summarizing notes (encoding), reviewing them over days (storage), and recalling facts during the test (retrieval).

Types of Long-Term Memory

• Explicit (Declarative) Memory: Conscious recall of facts and events.

  • Episodic Memory: Personal experiences and events.

  • Semantic Memory: General knowledge and facts.

• Implicit (Nondeclarative) Memory: Unconscious skills and procedures.

  • Procedural Memory: How to perform tasks (e.g., riding a bike).

  • Classical Conditioning Effects

Brain Structures Involved in Memory

• Hippocampus: Essential for forming new explicit memories.

• Amygdala: Involved in emotional memories.

• Cerebellum: Important for procedural memories.

• Prefrontal Cortex: Involved in working memory and retrieval.

Forgetting and Interference

• Forgetting: Can occur due to encoding failure, storage decay, or retrieval failure.

• Interference:

  • Proactive Interference: Old information interferes with new learning.

  • Retroactive Interference: New information interferes with old memories.

Example: Forgetting a new password because an old one is remembered (proactive interference).

Thinking and Intelligence

Key Terms in Cognition

• Role Schema: Expectations about how people in certain roles behave.

• Event Schema (Script): Expectations about the sequence of events in a given context.

• Heuristic: Mental shortcut for problem-solving; efficient but may lead to errors.

• Algorithm: Step-by-step procedure that guarantees a solution.

• Decision Biases: Systematic errors in judgment (e.g., confirmation bias, availability heuristic).

• Functional Fixedness: Inability to see new uses for familiar objects.

• Mental Set: Tendency to approach problems in a particular way, often based on past experience.

Theories of Intelligence

• Triarchic Theory (Sternberg): Intelligence consists of analytical, creative, and practical components.

• Multiple Intelligences (Gardner): Proposes several independent intelligences (e.g., linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal, intrapersonal, naturalistic).

• Emotional Intelligence: The ability to perceive, understand, manage, and use emotions effectively.

Lifespan Development

Prenatal Development

• Stages:

  1. Germinal: Conception to 2 weeks

  2. Embryonic: 2 to 8 weeks

  3. Fetal: 8 weeks to birth

• Teratogens: Environmental agents (e.g., drugs, viruses) that can cause harm during prenatal development.

Socioemotional Development

• Temperament: Innate traits that influence how one thinks, behaves, and reacts.

• Attachment: Emotional bond between infant and caregiver; types include secure, avoidant, ambivalent, and disorganized.

Cognitive Development (Piaget)

• Sensorimotor Stage (0-2 yrs): Experience world through senses and actions; object permanence develops.

• Preoperational Stage (2-7 yrs): Use of language and symbols; egocentrism and lack of conservation.

• Concrete Operational Stage (7-11 yrs): Logical thinking about concrete events; mastery of conservation.

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

Moral Development (Kohlberg)

• Preconventional Level: Obedience and self-interest.

• Conventional Level: Conformity and law/order.

• Postconventional Level: Social contract and universal ethical principles.

Physical Development

• Motor Skills: Development of movement and coordination.

• Puberty: Biological changes during adolescence leading to sexual maturity.

• Emerging Adulthood: Transitional period from late teens through twenties, bridging adolescence and full adulthood.

Theories of Motivation and Emotion

Motivation

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

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

• Drive Theory: Behavior is motivated by the desire to reduce internal tension caused by unmet biological needs.

• Hierarchy of Needs (Maslow): Needs are arranged in a hierarchy from physiological to self-actualization.

Associated Terms

• Overjustification Effect: External rewards can undermine intrinsic motivation.

• Yerkes-Dodson Law: Performance increases with arousal up to a point, then decreases if arousal is too high.

$Performance = f(Arousal)$

Emotion

• Components of Emotion: Physiological arousal, expressive behaviors, and conscious experience.

• Theories of Emotion:

  • James-Lange Theory: Emotion is the result of physiological responses to stimuli.

  • Cannon-Bard Theory: Physiological response and emotional experience occur simultaneously.

  • Schachter-Singer (Two-Factor) Theory: Emotion is determined by physiological arousal and cognitive labeling.

Theory	Main Idea
James-Lange	Emotion follows physiological arousal
Cannon-Bard	Emotion and arousal occur simultaneously
Schachter-Singer	Emotion = arousal + cognitive label
