PSY 200 Summary
Lifespan development is the study of how people grow, develop, and change throughout their lives. It covers the physical, cognitive, emotional, and social changes that occur from infancy through old age. Here's a basic summary of the key aspects of the subject:
1. Stages of Development
Lifespan development breaks life into stages, each with unique characteristics:
Prenatal (conception to birth): Rapid physical development begins, including the formation of organs, brain, and senses.
Infancy (birth to 2 years): The focus is on physical growth, motor skills, and basic cognitive development like learning to talk.
Early Childhood (2 to 6 years): Children develop social skills, language, basic problem-solving, and self-awareness.
Middle Childhood (6 to 12 years): Children’s cognitive skills and reasoning improve, and they begin forming more complex social relationships.
Adolescence (12 to 18 years): Teens undergo puberty, experience identity development, and explore independence.
Early Adulthood (18 to 40 years): Adults establish careers, relationships, and families, and there’s a focus on personal and professional growth.
Middle Adulthood (40 to 65 years): People may experience midlife changes, focus on career stability, and start reflecting on life achievements.
Late Adulthood (65+ years): People face physical decline, retirement, and changes in social roles. There’s an increased focus on life review and coping with aging.
2. Domains of Development
Development is usually studied across three main domains:
Physical development: Growth in the body and brain, including changes in motor skills, health, and senses.
Cognitive development: Changes in thinking, memory, problem-solving, and intelligence. Theories such as Piaget’s stages of cognitive development are key here.
Social and emotional development: How people form relationships, manage emotions, and develop their identities. Erikson’s psychosocial stages are often used to understand emotional growth.
3. Major Theories in Lifespan Development
Piaget’s Cognitive Development Theory: Focuses on how children learn to think, reason, and understand the world.
Erikson’s Psychosocial Theory: Emphasizes social relationships and emotional challenges at different stages of life.
Vygotsky’s Sociocultural Theory: Highlights the importance of social interaction and culture in learning and development.
Attachment Theory (Bowlby & Ainsworth): Examines the bonds between infants and caregivers and how these bonds influence future relationships.
4. Nature vs. Nurture Debate
A major aspect of lifespan development is understanding how genetics (nature) and environment (nurture) interact to shape a person’s growth.
5. Lifespan Perspective
The lifespan perspective emphasizes that development is lifelong, multidimensional, and plastic (flexible). It involves both gains and losses, and it's influenced by cultural, historical, and social factors.
