Document Summary
Developmental psychology is the study of how behaviour changes over the lifespan. Things that occur first don"t necessarily cause things that come later: 100 percent of serial killers drank milk as children, milk drinking creates mass murderers. Developmental influences are bidirectional, children"s experiences influence their development, but their development also influences their experiences. Parents influence their children"s behaviour, which in turn feeds back to influence their parents and so on. Cross-sectional design is a design in which researchers examine people of different ages at a single point in time. Developmental effects changes over time within individuals as a consequence of growing older. Externalizing behaviours- behaviours such as breaking rules, defying authority figures, and committing crimes. Although longitudinal designs are ideal for studying change over time, they can be costly and time-consuming. Attrition- participants dropping out of the study before it is completed.
