interest, the independent variable.
Control group does not receive this experience.
The dependent variable is a behavior that is
hypothesized to be affected by the independent
variable. 5 5/15/13 D. Designs for
Examining Development 1. Cross-Sectional 2. Longitudinal 3. Microgenetic 1. Cross-Sectional Designs
Children of different ages are compared
on a given behavior or characteristic over
a short period of time adavtnages: yields useful data amongst different age groups;
quick and easy to adminiser disadvantage: uninforming about stability or dinidviual difference
-uniformative about similarities and differences in inidviual
children's patterns of change 2. Longitudinal Designs
Used when the same children are studied
twice or more over a substantial period of
time advantage: indicates the degree of stability of individual
diffrence over long periods
-reveals individual children's patterns of change over long periods dis: difﬁcult to keep all partcipants in study
-repeadetly resting children can threaten exter...
