PS102 Lecture Notes - Lecture 5: Preterm Birth, Umbilical Cord, Prenatal Development
Document Summary
Examine changes in biological, physical, psychological and behavioural processes as we age. Critical and sensitive periods: critical period = age where experiences must occur, sensitive periods = optimal age range. Nature and nurture: which one is it? (usually both) Continuity vs discontinuity: gradual or stages. Inverted u-shape: emerges early peaks- diminishes with age. U-space function: emerges early disappears- re-emerges. Children memorizes their first ways they have no grammar. Longitudinal: test same cohort (people) at different times of the life span, pros. You can die before you finish your graph. Child may not accept to it as they get older.

Cross-sectional: compare different ages at the same time, pros. Data quickly from many ages groups: cons. Different cohorts grew up in different time periods. Sequential: test several cohorts as they age, cohort = group born at the same time.
