Bandura's theory:

The first step in the scientific method involves:

posing a question. running an experiment. selecting a group of participants. asking people to participate.

You notice your grandparents, who are in their 80s, seem to look smaller than they did in the home movies you have been watching. Your cousin disagrees and says it is an illusion. How would a developmental psychologist settle your disagreement?

a) The observation is not an illusion; the spinal column actually shrinks in late adulthood. b) The observation is an illusion, which can be explained by the Gestalt principle of good continuation. c) The observation is not an illusion; however, it is the result of differences in the diets of elderly and young people. d) The observation is not accurate; perceived height among the elderly is a function of the individuals who are standing around them.
