PS102 Lecture Notes - Lecture 16: Miscarriage, Adult Attention Deficit Hyperactivity Disorder, Xyy Syndrome
Document Summary
Critical and sensitive periods: critical period = age where experiences must occur, sensitive periods = optimal age range. That"s okay, it can happen later and that"s fine. A no change: remains constant, flat, horizontal line. B continuous: gradual changes, smooth curve. C stages: discontinuous changes, stair-like. D inverted u-shape: emerges early -> peaks -> diminishes with age. E u-shape function: emerges early -> disappears -> re-emerges. Same people being used reduces the variability across samples. Can changes observed be generalized to all people or just this group. You have different cohorts that grew up in different time periods. Participants have different experiences, cultural changes, environmental changes. Cross-sectional sequential design: test several cohorts as they age, cohort = group born at same time, has the pros and cons of both the longitudinal and cross-sectional designs. Zygote attaches to uterine wall: embryonic stage. Where drug injuries can occur: fetal stage. At 7 months, the baby has a good chance of surviving unassisted.
