Cumulative Study Guide: Foundations of Psychology

Introduction to Psychology

Definition and Goals of Psychology

Psychology is the scientific study of behavior and mental processes. It aims to describe, explain, predict, and control behavior and mental events.

• Description: Observing and describing behaviors or mental processes as objectively and accurately as possible.

• Explanation: Understanding why a behavior or mental process occurs by identifying causes, mechanisms, or principles.

• Prediction: Anticipating when and under what conditions a behavior or mental process will occur in the future.

• Control: Attempting to influence or manage a mental process or behavior to be more useful or beneficial.

Major Perspectives in Psychology

• Biological: Behavior is shaped through genetics, neurotransmitters, and brain structures.

• Cognitive: Focuses on how mental processes such as thinking, memory, and problem-solving influence behavior.

• Behavioral: Emphasizes learning through conditioning and observable behavior.

• Humanistic: Concentrates on free will, self-actualization, and personal growth.

• Psychodynamic: Explores unconscious motives and early childhood experiences.

• Sociocultural: Studies how culture and social context shape behavior.

• Evolutionary: Looks at behavior through adaptation and survival.

Subfields in Psychology

• Clinical: Assessment, diagnosis, and treatment of psychological disorders.

• Counseling: Helps individuals with life challenges, emotional difficulties, and adjustment problems.

• Developmental: Studies physical, cognitive, and socioemotional changes across the lifespan.

• Industrial-Organizational: Applies psychological principles to workplace behavior.

• Health Psychology: How students think and behave in health situations.

• Cognitive: Thinking, problem-solving, and memory.

• Biopsychology/Neuropsychology: Studies the relationship between brain and behavior.

Psychology Research

The Scientific Method

The scientific method is a systematic approach to research that involves forming hypotheses, collecting data, and drawing conclusions.

• Hypothesis: A specific, testable prediction about the relationship between variables.

• Variables: Elements that can change or be controlled in an experiment.

• Independent Variable: Manipulated by the researcher.

• Dependent Variable: Measured outcome.

• Extraneous Variables: Other factors that must be controlled.

Ethics in Psychological Research

• Informed Consent: Participants must be informed about the study and consent voluntarily.

• Confidentiality: Protecting participant privacy.

• Debriefing: Explaining the study after participation.

• Minimizing Harm or Distress: Ensuring participant well-being.

Biological Psychology

Structure and Function of Neurons

Neurons are the basic building blocks of the nervous system, responsible for transmitting information throughout the body.

• Dendrites: Branch-like extensions that receive messages from other neurons.

• Axon: Long fiber that carries electrical impulses (action potentials) away from the neuron’s cell body.

• Synapse: Gap between neurons where communication occurs.

Neurotransmitters

Chemical messengers that transmit signals across the synapse, including dopamine, serotonin, and acetylcholine.

Central and Peripheral Nervous System

• Central Nervous System (CNS): Brain and spinal cord; responsible for processing, integrating, and responding to information.

• Peripheral Nervous System (PNS): Connects CNS to the rest of the body; includes somatic (voluntary) and autonomic (involuntary) systems.

The Brain

• Hindbrain: Basic survival functions (breathing, heartbeat, reflexes).

• Midbrain: Involved in movement and processing sensory information.

• Forebrain: Largest, most complex part; includes emotion, reasoning, and memory.

Neuroplasticity

The brain’s ability to change and adapt, especially strong in childhood.

Memory

Stages of Memory

• Sensory Memory: Briefly holds sensory information.

• Short-Term Memory (STM): Temporary holding space for information we’re actively using.

• Long-Term Memory (LTM): Relatively permanent and limitless storehouse of knowledge.

Types of Long-Term Memory

• Explicit (Declarative) Memory: Conscious recall (semantic and episodic).

• Implicit (Procedural) Memory: Without conscious awareness (skills, habits).

Encoding, Storage, Retrieval

• Encoding: Transforming information for storage.

• Storage: Maintaining information over time.

• Retrieval: Getting stored information back into conscious awareness.

Forgetting

• Decay: Memory fades over time if not used or rehearsed.

• Interference: New or old information disrupts retrieval.

• Motivated Forgetting: Forgetting something because it is unpleasant or unwanted.

• Amnesia: Loss of memory due to injury or trauma.

Memory Reconstruction and Eyewitness Reliability

• Memory is not a perfect record; it is reconstructed each time we recall it.

• Eyewitness accounts can be influenced by suggestions, stress, and expectations.

Learning

Classical Conditioning

Learning through association, as demonstrated by Pavlov’s experiments.

• Neutral Stimulus (NS): Does not naturally produce a response.

• Unconditioned Stimulus (US): Naturally triggers a response.

• Unconditioned Response (UR): Natural reaction to the US.

• Conditioned Stimulus (CS): Previously neutral, now triggers response after association.

• Conditioned Response (CR): Learned response to the CS.

Operant Conditioning

Learning in which behavior is strengthened or weakened depending on consequences.

• Reinforcement: Increases behavior (positive or negative).

• Punishment: Decreases behavior (positive or negative).

• Shaping: Teaching complex actions by rewarding steps toward desired behavior.

Schedules of Reinforcement

Type	Description
Fixed Ratio (FR)	After a set number of responses (e.g., every 10th behavior)
Fixed Interval (FI)	After a set amount of time (e.g., every week)
Variable Ratio (VR)	After an unpredictable number of responses (e.g., slot machines)
Variable Interval (VI)	After changing amounts of time (e.g., checking email)

Observational Learning (Bandura)

Learning by watching others rather than direct experience. Includes attention, retention, reproduction, and motivation.

Cognitive Influences on Learning

• Expectancy: Learning is influenced by what a person expects to happen.

• Insight Learning: Sudden realization of a solution (“aha!” moment).

• Learned Helplessness: Repeated failure leads to giving up.

Cognition and Intelligence

Components of Cognition

• Thinking: Manipulation of information to form concepts, solve problems, make decisions, imagine, and reason.

• Reasoning: Drawing conclusions based on evidence.

• Problem Solving: Reaching goals by identifying problems and generating solutions.

• Decision Making: Choosing between alternatives.

Problem-Solving Barriers

• Confirmation Bias: Tendency to search for information that confirms existing beliefs.

• Mental Set: Using strategies that worked in the past, even if not effective now.

• Functional Fixedness: Seeing objects as having only one use, which prevents creative problem solving.

Theories of Intelligence

• Spearman’s “g”: General intelligence factor.

• Gardner’s Multiple Intelligences: Several independent types (linguistic, logical-mathematical, spatial, musical, interpersonal, intrapersonal, etc.).

• Sternberg’s Triarchic Theory: Analytical, creative, and practical intelligence.

Measuring Intelligence

• IQ Tests: Standardized tests measuring cognitive ability.

• Reliability: Consistency of a test.

• Validity: Accuracy of a test in measuring what it claims to measure.

Emotional Intelligence and Creativity

• Emotional Intelligence (EI): Ability to recognize, understand, and manage emotions.

• Creativity: Ability to produce novel and valuable ideas.

Developmental Psychology

Developmental Domains

• Physical: Changes in the body, brain, motor skills, hormones, and overall biological processes.

• Cognitive: Growth in mental abilities such as thinking, learning, memory, language, and intelligence.

• Socioemotional: Changes in relationships, emotional regulation, and personality.

Prenatal Development and Teratogens

• Prenatal Development: Occurs in three stages: germinal, embryonic, fetal.

• Teratogens: Environmental factors that can damage the developing embryo/fetus (e.g., drugs, alcohol, infections).

Major Theories

• Piaget: Cognitive stages (sensorimotor, preoperational, concrete operational, formal operational).

• Erikson: Psychosocial stages (each with a central conflict).

• Vygotsky: Sociocultural theory (emphasizes social interaction and guidance).

Attachment Types

• Secure: Child explores, comforted by caregiver.

• Avoidant: Child avoids caregiver, shows little distress.

• Ambivalent (Resistant): Child is very distressed by separation, difficult to soothe.

Adolescence, Adulthood, and Aging Milestones

• Adolescence: Puberty, identity development, increased independence.

• Adulthood: Career exploration, relationships, family life.

• Aging: Physical changes, cognitive decline, changes in social roles.

Emotion and Motivation

Biological and Psychological Motives

• Hunger: Regulated by the brain and hormones.

• Achievement: Desire to accomplish goals.

• Belonging: Need for social connection.

• Self-Actualization: Reaching full potential (Maslow).

Theories of Motivation

• Drive-Reduction Theory: Behavior motivated by desire to reduce internal tension.

• Arousal Theory: People seek optimal levels of arousal.

• Incentive Theory: Behavior motivated by external rewards.

• Maslow’s Hierarchy of Needs: Needs arranged from basic to advanced.

Theories of Emotion

• James-Lange: Emotion results from physiological changes.

• Cannon-Bard: Emotion and physiological arousal occur simultaneously.

• Schachter-Singer Two-Factor: Emotion is based on physiological arousal and cognitive interpretation.

Stress and Health

Stress and Coping

• Stress: Physical and psychological response to challenges.

• Emotion-Focused Coping: Managing emotional reaction to stress.

Personality

Major Theories

• Psychoanalytic (Freud): Personality shaped by unconscious drives and early experiences.

• Humanistic (Rogers, Maslow): Focus on self-actualization and personal growth.

• Trait (Big Five): Describes personality in terms of stable, measurable characteristics.

• Social-Cognitive (Bandura): Emphasizes learning, thinking, and social influences.

Personality Assessment
