Introduction: Discovering The Lifespan 5th Edition
Discovering the Lifespan, 5th Editionprovides a comprehensive overview of human development from conception to late adulthood. The book covers the physical, cognitive, social, and emotional changes that occur throughout the lifespan, and explores the factors that influence development, such as genetics, environment, and culture.
Human Development Across the Lifespan
Prenatal Development
Prenatal development begins at conception and lasts until birth. During this period, the embryo and fetus undergo rapid physical growth and development. The major organs and body systems are formed, and the fetus begins to move and respond to stimuli.
Infancy
Infancy begins at birth and lasts until about 18 months. During this period, infants experience rapid physical, cognitive, and social-emotional development. They learn to walk, talk, and interact with others. They also develop a sense of self and begin to form attachments to their caregivers.
Early Childhood
Early childhood lasts from about 18 months to 6 years. During this period, children continue to experience rapid physical, cognitive, and social-emotional development. They become more independent and develop a sense of autonomy. They also begin to develop friendships and learn to cooperate with others.
Middle Childhood
Middle childhood lasts from about 6 to 11 years. During this period, children continue to experience physical, cognitive, and social-emotional development. They become more competent and confident in their abilities. They also develop a sense of morality and begin to understand the rules of society.
Adolescence
Adolescence begins at about 11 years and lasts until about 18 years. During this period, adolescents experience rapid physical, cognitive, and social-emotional changes. They become more independent and develop a sense of identity. They also begin to form romantic relationships and explore their sexuality.
Early Adulthood
Early adulthood begins at about 18 years and lasts until about 40 years. During this period, adults continue to experience physical, cognitive, and social-emotional development. They reach their peak physical strength and reproductive capacity. They also develop a sense of purpose and begin to establish their careers and families.
Middle Adulthood
Middle adulthood begins at about 40 years and lasts until about 65 years. During this period, adults experience gradual physical, cognitive, and social-emotional changes. They begin to lose some of their physical strength and reproductive capacity. They also may experience changes in their career and family life.
Late Adulthood
Late adulthood begins at about 65 years and lasts until death. During this period, adults experience significant physical, cognitive, and social-emotional changes. They become more frail and may experience health problems. They also may retire from their careers and spend more time with their families and friends.
Research Methods in Developmental Psychology
Observational Methods, Discovering the lifespan 5th edition
Observational methods involve observing children and adolescents in their natural settings. These methods can be used to study a wide range of behaviors, from social interactions to cognitive development.
Experimental Methods
Experimental methods involve manipulating one or more variables to determine their effects on behavior. These methods can be used to test hypotheses about the causes of development.
Correlational Methods
Correlational methods involve measuring the relationship between two or more variables. These methods can be used to identify factors that are associated with development, but they cannot be used to determine cause and effect.
Longitudinal Studies
Longitudinal studies follow the same group of children or adolescents over a period of time. These studies can provide valuable information about the changes that occur during development.
Cross-sectional Studies
Cross-sectional studies compare children or adolescents of different ages at one point in time. These studies can provide a snapshot of the developmental changes that occur at different ages.
Ethical Considerations
When conducting research with children and adolescents, it is important to consider the ethical implications. These considerations include obtaining informed consent, protecting the privacy of participants, and minimizing any potential risks.
Physical Development
Prenatal Development
During prenatal development, the fetus undergoes rapid physical growth and development. The major organs and body systems are formed, and the fetus begins to move and respond to stimuli.
Infancy
During infancy, infants experience rapid physical growth and development. They gain weight and height, and their head circumference increases. They also develop motor skills, such as walking and talking.
Early Childhood
During early childhood, children continue to experience physical growth and development. They become more coordinated and develop fine motor skills, such as drawing and writing.
Middle Childhood
During middle childhood, children experience a period of relatively slow physical growth. They begin to lose their baby fat and develop a more muscular appearance. They also reach their adult height.
Adolescence
During adolescence, adolescents experience a period of rapid physical growth and development. They gain weight and height, and their bodies begin to mature. They also develop secondary sexual characteristics, such as breasts in girls and facial hair in boys.
Early Adulthood
During early adulthood, adults reach their peak physical strength and reproductive capacity. They may also experience some changes in their body composition, such as a decrease in muscle mass and an increase in body fat.
Middle Adulthood
During middle adulthood, adults begin to experience gradual physical changes. They may lose some of their physical strength and reproductive capacity. They also may experience changes in their body composition, such as a further decrease in muscle mass and an increase in body fat.
Late Adulthood
During late adulthood, adults experience significant physical changes. They become more frail and may experience health problems, such as heart disease, stroke, and cancer. They also may experience changes in their body composition, such as a further decrease in muscle mass and an increase in body fat.
