PSYC101 Final Exam Review: Comprehensive Study Guide

Overview of Psychology

What is Psychology?

Psychology is the scientific study of behavior and mental processes. It seeks to understand individuals and groups by establishing general principles and researching specific cases.

• Father of Psychology in the United States: William James is often credited as the father of American psychology.

• Founding of Psychology: Psychology emerged as a distinct scientific discipline in the late 19th century, with Wilhelm Wundt founding the first laboratory in Germany.

Modern-Day Perspectives in Psychology

• Psychodynamic Perspective: Focuses on unconscious processes and childhood experiences (Freud).

• Evolutionary Perspective: Examines how evolutionary principles such as natural selection influence behavior.

• Behavioral Perspective (Behaviorism): Studies observable behavior and the effects of learning.

• Biopsychological Perspective: Explores the biological bases of behavior, including genetics and neurochemistry.

• Cognitive Perspective: Investigates mental processes like thinking, memory, and problem-solving.

• Humanistic Perspective: Emphasizes personal growth and self-actualization (Maslow, Rogers).

• Sociocultural Perspective: Considers how social and cultural factors affect behavior.

Scientific Method in Psychology

Steps of the Scientific Method

The scientific method is a systematic approach to research in psychology.

• Step 1: Formulate a research question.

• Step 2: Develop a hypothesis.

• Step 3: Design and conduct an experiment.

• Step 4: Analyze the data.

• Step 5: Draw conclusions.

Experiment: A controlled method of investigation to establish cause-and-effect relationships.

Case Study: In-depth analysis of a single individual or group.

Naturalistic Observation: Observing subjects in their natural environment without interference.

Correlation: Measures the relationship between two variables, but does not imply causation.

Independent Variable: The variable manipulated by the researcher.

Dependent Variable: The variable measured to assess the effect of the independent variable.

Institutional Review Board (IRB): A committee that reviews research proposals to ensure ethical standards are met.

Biological Perspective

Lobes of the Cerebral Cortex

• Frontal Lobe: Responsible for reasoning, planning, movement, and problem-solving.

• Parietal Lobe: Processes sensory information such as touch, temperature, and pain.

• Temporal Lobe: Involved in hearing, memory, and language.

• Occipital Lobe: Processes visual information.

Neurotransmitters

• GABA: Inhibitory neurotransmitter; reduces neuronal excitability.

• Serotonin: Regulates mood, appetite, and sleep.

• Dopamine: Involved in reward, motivation, and motor control.

• Endorphins: Natural painkillers; promote feelings of well-being.

Sympathetic and Parasympathetic Nervous Systems

• Sympathetic Nervous System: Activates "fight or flight" response during stress.

• Parasympathetic Nervous System: Promotes "rest and digest" functions.

Sensation and Perception

Sensory Systems

• Sense of Smell: Olfaction.

• Sense of Taste: Gustation.

• Sensory Adaptation: Reduced sensitivity to constant stimulation.

• Synesthesia: A condition where stimulation of one sensory pathway leads to automatic, involuntary experiences in a second pathway.

Consciousness

Sleep and Insomnia

• Ways to Decrease Insomnia: Maintain a regular sleep schedule, avoid caffeine before bed, create a comfortable sleep environment, and practice relaxation techniques.

Learning

Classical Conditioning

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

• Reinforcement: Increases the likelihood of a behavior.

• Punishment: Decreases the likelihood of a behavior.

• Observational Learning: Learning by watching others (Bandura).

• Latent Learning: Learning that occurs but is not immediately demonstrated.

• Systematic Desensitization: Gradual exposure to a feared stimulus paired with relaxation.

• Aversion Therapy: Pairing an unwanted behavior with an unpleasant stimulus.

Memory

Stages of Memory

• Sensory Memory: Brief storage of sensory information.

• Short-Term Memory: Temporary storage for information being used.

• Long-Term Memory: Permanent storage of information.

Serial Position Effect: Tendency to recall the first and last items in a list better than the middle items.

Anterograde Amnesia: Inability to form new memories after an event.

Retrograde Amnesia: Inability to recall memories formed before an event.

Infantile Amnesia: Inability to recall events from early childhood.

Elaborative Rehearsal: Memory-enhancing technique involving linking new information to existing knowledge.

Cognition: Thinking, Intelligence, and Language

Theories of Intelligence

• Charles Spearman: Proposed the "g factor" (general intelligence).

• Howard Gardner: Theory of multiple intelligences (e.g., linguistic, logical-mathematical, spatial).

• Raymond Cattell: Distinguished between fluid and crystallized intelligence.

• Robert Sternberg: Triarchic theory (analytical, creative, practical intelligence).

Confirmation Bias: Tendency to search for, interpret, and remember information that confirms one's beliefs.

Development Across the Life Span

Jean Piaget’s Theory of Cognitive Development

• Sensory-Motor Stage: Birth to 2 years; learning through senses and actions.

• Preoperational Stage: 2 to 7 years; symbolic thinking, egocentrism.

• Concrete Operational Stage: 7 to 11 years; logical thinking about concrete events.

• Formal Operational Stage: 12 years and up; abstract reasoning.

Mary Ainsworth’s Attachment Styles

• Secure Attachment: Child feels safe and confident.

• Anxious-Ambivalent Attachment: Child is anxious and uncertain.

• Avoidant Attachment: Child avoids closeness.

Erik Erikson’s Psychosocial Stages

Stage	Age Range	Crisis
Trust vs. Mistrust	0-1 years	Developing trust in caregivers
Autonomy vs. Shame and Doubt	1-3 years	Developing independence
Initiative vs. Guilt	3-6 years	Initiating activities
Ego Integrity vs. Despair	Late adulthood	Reflecting on life

Lawrence Kohlberg’s Levels of Moral Development

• Preconventional: Obedience and self-interest.

• Conventional: Conformity and law/order.

• Postconventional: Universal ethical principles.

Motivation and Emotion

Motivation Theories

• Drive-Reduction Theory: Motivation arises from biological needs.

• Extrinsic Motivation: Driven by external rewards.

• Intrinsic Motivation: Driven by internal satisfaction.

• Regulatory Focus Theory: Distinguishes between promotion and prevention focus in motivation.

• Yerkes-Dodson Law: Performance increases with arousal up to a point, then decreases. $Performance = f(Arousal)$

• Abraham Maslow’s Hierarchy of Needs: Pyramid of human needs, from physiological to self-actualization.

Sexuality

• William Masters and Virginia Johnson: Studied the physiology of human sexual response.

• Alfred Kinsey: Conducted pioneering research on sexual behavior and orientation.

• Sexual Orientation: Includes homosexual, heterosexual, bisexual/pansexual, and asexual identities.

• Kinship Theory: Explains altruistic behavior in terms of genetic relatedness.

Stress and Health

Stress and Coping

• Stress: The body's response to challenging or threatening situations.

• Coping Strategies: Methods for managing stress.

• Problem-Focused Strategies: Address the source of stress directly.

• Emotion-Focused Strategies: Manage emotional responses to stress.

• Cultural Differences: The experience and management of stress can vary across cultures.

Social Psychology

Key Experiments

• Solomon Asch’s Experiment: Studied conformity in groups.

• Stanley Milgram’s Experiment: Investigated obedience to authority.

• Philip Zimbardo’s Experiment: Stanford Prison Experiment; examined the power of roles and situational factors.

Fundamental Attribution Error: Tendency to overemphasize personality and underestimate situational factors; affected by culture.

Worldview: The overall perspective from which one sees and interprets the world.
