Document Summary

Chapter 12 development over the life span. Developmental psychology examines changes in biological, physical, psychological, and behavioural processes over age. Four issues guide developmental research: nature and nurture (heredity vs. environment, critical and sensitive periods. Critical period an age range during which certain experiences must occur for normal development. Sensitive period an optimal age range for certain experiences, but no critical range: continuity versus discontinuity (gradual development vs. distinct stages, stability versus change (do characteristics remain the same?) Inverted u-shaped function an ability that peaks at a certain age, then decreases. Different designs used to research: cross-sectional design research design that compares people of different age groups at same point in time. Drawback in that different age groups (cohorts) grew up in different periods: longitudinal design repeatedly tests same cohort as it grows older, sequential design combination of other two, which tests multiple cohorts over their lives.
