Flashcards in Physical Development in Infancy Deck (12):
1

Developmental Psychology

study of human physical, cognitive, social, behavioural characteristic across the lifespan

2

Cross Sectional Design

measure and compare same of people at different ages at a given point in time
i.e. study different age groups (1, 5, 10 year olds)

3

Longitudinal Design

follows development of same set of individuals through time
i.e. select sample of infants and measure their development over the course of 20 years

4

Cohort Effects

differences between people that result from being born in different time period
i.e problem with cross sectional design

5

Attrition

Visual Cliff

infants can understand depth
- would be be reluctant to crawl over to deep side
