Document Summary
The study of changes in behaviour and mental processes: child development, adolescent development, aging, family, exceptional development, sexuality. To capture change, must study things in context of time: longitudinal studies. Measure a specific variable at time 1. Measure again at a later point time 2. Perry preschool project: 1962 (ages 3 and 4) inner city, african-american families, n=123, randomly assigned to one of two groups: Control: no preschool: followed to age 40 to see the impact of early childhood education, compared iq and behaviour over lifetime. Participant mortality: drop out or can"t find. Historic effects: cross-sectional, events that only happen to these kids (e. g. 9/11) Measure different age groups across a variety of ages, all at a single point in time. Different individuals in each group: may have different historic effects, may not have same outcomes. Behavioural changes across the lifespan: lifespan stages, different aspects important at different stages. 3 distinct phases: germinal phase (zygote) first 2 weeks after conception.
