Document Summary

The study of changes in behaviour and mental processes. To capture change, must study things in the context of time. Measure a specific variable at time 1. Measure again at a later point (time 2) Followed to age 40 to look at the impact. Major findings: iq 90+ at 5, homework at 13, basic achievement at 14, graduated regular high school, earned 20k at 40, arrested 5+ times by 40. Events that only happen to these kids (e. g. , 9-11, plane crash) Measure different age groups across a variety of ages, all at a single point in time. 3 distinct phases: germinal phase (zygote): first 2 weeks after conception. The percentage of conceptions that do not make it past the zygote phase is. 80: embryonic stage: 2 weeks to 2 months, fetal stage: 2 months to birth. The percentage of conceptions that do not make it past the zygote phase is 80% Many fertilized eggs don"t make it past this stage.
