Professor rashad is interested in studying cognitive development. he collects and compares data from a group of 6-year-olds and a group of 10-year-olds. five years later, he compares these two groups to each other again as well as to their own performance in the study five years ago. what type of research design is professor rashad using? cross-sequential design longitudinal design behavior genetics design cross-sectional design applied behavior analysis design

cross-sequentional design

Explanation:

A cross-sequential design is a combination of a longitudinal (analizes the same variable for example a group of people, over a period of time) and a cross-sectional design (analizes data at a specific point of time).

Cross-sequational method in the example given is comparing different groups of people at different times.

manifest functions are the recognized and intended consequences of any social pattern, while latent functions are those unrecognized and unintended consequences. to analyze the manifest functions of any social institution, we have to study its contribution to the continuation of a group, community, or society.
