Document Summary

Chapter 11 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, 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 o. Five developmental functions: no change an ability from birth remains constant over life span, continuous an ability that develops gradually and then remains constant, discontinuity an ability that progresses in stages o. Inverted u-shaped function an ability that peaks at a certain age, then decreases: u-shaped function an ability that disappears temporarily. 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.
