Document Summary

Developmental psychology - the study of how behavior changes over time. Special considerations: post hoc fallacy false assumption that because one event occurred before another event, it must have caused that event. Bidirectional influences: children"s biological make-up influences their experiences, but their biological make up is also influenced by their influences. Cross-sectional design examine people of different ages at a single time point: cohort effect. Longitudinal design track the development of the same group of people over time: able to control for cohort effects to a larger extent, still not a true experiment. Longitudinal design: controlling for confounds, extremely time consuming, decades on 1 experiment. Cross-sectional: findings may be discovered more quickly. The best researchers attempt to use both/some form of hybrid. Infant determinism assumption that extremely early experiences are more influential in our development than later experiences: actually, experiences shape us throughout development. Childhood fragility assumption that children are extremely delicate: they are very resilient. Nature genetics nurture environment.
