Chapter 4 Flashcards
Lifespan Development
Human development from conception to death. Blend of genetics, culture, environment, relationships, and more. Focus on how people change
Physical Development
Changes in body, brain, skills, etc
Cognitive Development
Changes in learning, attention, memory, language, etc
Psychosocial Development
Changes in emotions, personality, relationships, etc
Research Methods
Naturalistic, case studies, surveys, experiments, correlational studies
Cross-Sectional Design
Recruits people of different ages to collect data on the same outcome. Convenient, quick, and easy, but results are subject to cohort effects (are differences real or related to differential exposure?)
Longitudinal Design
Recruits the same people at different points in time (e.g., different ages). Reduces cohort effect and can support causal inferences, but costs time and money and is subject to attrition
Longitudinal Sequential
The most comprehensive design (combination of Cross-sectional and longitudinal designs). Recruits people of different ages and follows these same people at different points in time (different ages across the same timeframe)
Continuous Development
View that development is a cumulative process: gradually improving on existing skills
Discontinuous Development
View that development happens in unique stages, which happen at specific times or ages
Nature
Genes and biology. What you’re born with (genes for freckles and dimples)
Nurture
Environment and culture. How you’re raised (attitudes, beliefs, values)
Nature vs. Nurture
Inseparable. Evidence suggests that the two interact (gene-environment interactions). Experiences can turn genes on or off. The debate now focuses on relative contribution rather than which best explains behaviour
Psychosexual Theory
Developed by Freud. Personality develops and is shaped by early childhood experiences. Children are pleasure-seeking. Discontinuous (stage-like) development. Stages are oral, anal, phallic, latency, and genital.
Psychosocial Stages
8 developmental stages developed by Erik Erikson. Each stage associated with a different drive and a problem or crisis to resolve. Occurs through to adulthood. Conflict/task in stages drives development via mastery. Failure = inadequacy
Stage 1
Birth - 1 year
Stage 2
1-3 years
Stage 3
3-5 years
Stage 4
5-12 years
Stage 5
Adolescence
Stage 6
Young adulthood
Stage 7
Middle adulthood
Stage 8
Late adulthood - death
Trust vs. Mistrust
Stage 1. Infants must rely on others for care. Consistent and dependable caregiving and meeting infant needs leads to a sense of trust, Infants who are not well cared for develop a sense of mistrust
Autonomy vs. Shame and Doubt
Stage 2. Babies discovering their own independence. Those given the opportunity to experience independence will develop a sense of autonomy. Children who are overly restrained or punished harshly will develop shame and doubt.
Initiative vs. Guilt
Stage 3. Children are exposed to the wider social world and given greater responsibility. Sense of accomplishment lead to initiative, whereas feelings of guilt can emerge if the child is made to feel too anxious or irresponsible
Industry vs. Inferiority
Stage 4. Mastery of knowledge and intellectual skills. Sense of competence and achievement leads to industry. Feeling incompetent and unproductive leads to inferiority
Identity vs. Confusion
Stage 5. Developing a sense of who one is and where they are going in life. Successful resolution leads to positive identity. Unsuccessful resolution leads to identity confusion and a negative identity
Intimacy vs. Isolation
Stage 6. Time for sharing oneself with another person. Capacity to hold commitments with others leads to intimacy. Failure to establish commitments leads to feelings of isolation
