Development Through the Lifespan & Social Psychology: Study Guide

Development Through the Lifespan

Introduction to Developmental Psychology

Developmental psychology studies the changes in physical, cognitive, and social abilities across the lifespan. It seeks to understand how people grow, develop, and adapt at different life stages.

• Developmental Psychologists: Study phenomena such as language acquisition, moral reasoning, and identity formation.

• Nature vs. Nurture Debate: Considers the relative influence of genetics (nature) and environment (nurture) on development.

• Research Methods: Includes longitudinal, cross-sectional, and sequential designs.

Physical Development: Maturation and Milestones

Physical maturation refers to the biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience.

• Stages of Prenatal Development: Germinal, embryonic, and fetal stages.

• Critical Periods: Specific times during which certain skills or abilities are most easily learned.

• Importance of Early Experiences: Early nutrition, stimulation, and attachment can have lasting effects on development.

Cognitive and Moral Development

Cognitive development involves changes in thinking, problem-solving, and decision-making abilities. Moral development refers to the evolution of standards of right and wrong.

• Schema: A mental framework for organizing information.

• Assimilation and Accommodation: Processes by which children incorporate new information into existing schemas or adjust schemas to fit new information.

• Piaget's Stages: Sensorimotor, preoperational, concrete operational, and formal operational stages.

• Kohlberg's Theory of Moral Development: Preconventional, conventional, and postconventional levels.

Social and Emotional Development

Social and emotional development focuses on how individuals form relationships, regulate emotions, and develop a sense of self.

• Attachment: The emotional bond between a child and caregiver. Types include secure, avoidant, and ambivalent attachment.

• Parenting Styles: Authoritative, authoritarian, permissive, and uninvolved.

• Erikson's Stages of Psychosocial Development: Eight stages from infancy to adulthood, each characterized by a central conflict.

Adolescence: Physical and Cognitive Changes

Adolescence is marked by rapid physical growth, sexual maturation, and cognitive development.

• Primary and Secondary Sex Characteristics: Primary involve reproductive organs; secondary include features such as breast development and voice changes.

• Identity Formation: Adolescents explore different roles and integrate them to form a stable identity.

Gender and Sexuality

Gender development involves understanding gender identity, roles, and sexual orientation.

• Gender Identity: One's sense of being male, female, or another gender.

• Gender Roles: Societal expectations for behaviors and attitudes based on gender.

• Transgender and Nonbinary Identities: Individuals whose gender identity differs from their assigned sex at birth.

• Sexual Orientation: Enduring pattern of romantic or sexual attraction to others.

Sexual Health and Behavior

Sexual health includes understanding sexually transmitted infections (STIs), sexual orientation, and sexual dysfunctions.

• STIs: Infections transmitted through sexual contact, such as HIV/AIDS, chlamydia, and gonorrhea.

• Sexual Response Cycle: Phases include excitement, plateau, orgasm, and resolution.

• Sexual Dysfunction: Problems that interfere with sexual functioning, such as erectile disorder or female orgasmic disorder.

Social Psychology

Introduction to Social Psychology

Social psychology examines how individuals think, feel, and behave in social contexts.

• Attribution Theory: Explains how people interpret the causes of behavior, distinguishing between internal (dispositional) and external (situational) attributions.

• Fundamental Attribution Error: The tendency to overemphasize dispositional factors and underestimate situational factors when explaining others' behavior.

Attitudes and Persuasion

Attitudes are evaluations of people, objects, or ideas, and can influence behavior.

• Cognitive Dissonance: The discomfort experienced when holding conflicting beliefs or behaviors, often leading to attitude change.

• Persuasion Techniques: Methods such as the foot-in-the-door and door-in-the-face techniques are used to change attitudes.

Obedience and Conformity

Obedience and conformity are forms of social influence that affect individual behavior.

• Milgram's Obedience Study: Demonstrated the power of authority in compelling individuals to act against their conscience.

• Asch's Conformity Experiments: Showed how group pressure can lead individuals to conform to incorrect judgments.

Group Behavior

Group dynamics influence individual behavior, decision-making, and attitudes.

• Groupthink: The tendency for group members to seek consensus without critically evaluating alternatives.

• Social Facilitation: Improved performance on simple tasks in the presence of others.

• Social Loafing: The tendency for individuals to exert less effort when working in a group.

Prejudice, Discrimination, and Stereotypes

Prejudice is a negative attitude toward a group, discrimination is negative behavior, and stereotypes are generalized beliefs.

• Implicit vs. Explicit Prejudice: Implicit prejudice is unconscious, while explicit prejudice is conscious and deliberate.

• Reducing Prejudice: Strategies include intergroup contact and cooperative activities.

Aggression and Helping Behavior

Aggression refers to behavior intended to harm others, while helping behavior (prosocial behavior) benefits others.

• Frustration-Aggression Hypothesis: Suggests that frustration leads to aggressive behavior.

• Bystander Effect: The tendency for individuals to be less likely to help when others are present.

• Kitty Genovese Case: A famous example illustrating the bystander effect.

Example Table: Parenting Styles

Parenting Style	Characteristics	Child Outcomes
Authoritative	High warmth, high control	High self-esteem, social competence
Authoritarian	Low warmth, high control	Low self-esteem, obedience
Permissive	High warmth, low control	Impulsivity, poor self-regulation
Uninvolved	Low warmth, low control	Poor social and academic outcomes
