PS102 Lecture Notes - Lecture 12: Preterm Birth, Prenatal Development, Longitudinal Study
Document Summary
Examines: changes in biological, physical, psychological, and behavioural processes as we age. The big questions: critical and sensitive periods critical period = age where experience must occur. Continuity vs discontinuity: gradual or stages ? sensitive period = optimal age range short duration (few weeks, few months, a yr) longer range (cid:523)should be ok if it(cid:495)s a little bit earlier/later(cid:524) Stages is discontinuous development keep changing in each stage; change dramatically either quantitative or qualitative. Flat line = no change developmentally; remains constant; that characteristics is static across lifespan. Nice curve = continuous, gradual change; will plateau eventually child changes little bit over time along the yrs. Stairs = disjointed = stages, discontinuous change; abrupt change; stage theory data looks like this (i. e. irregular english past tense, irregular english verbs i went, i goed, i went) Inverted u-shape = emerges early; peaks; diminishes with age, then disappears (e. g. processing speech)
