Before responding to this problem, please read "A trip to the zoo: Children's words and photographs" research article. Note the key differences in photographs and descriptions between the younger and older children. Use this article and your understanding of cognitive development (especially Piaget, Vygotsky, or information processing) to respond to the problems.

1. Using the cognitive development theory of your choice, compare the differences in photographs and descriptions between children in the youngest group and the older children. Why are their perceptions of what they saw so different from each other?

2. Propose a follow-up study that would support your conclusions about the cognitive differences between younger and older children. Be creative and use the same cognitive development theory as you did to respond to the first problem.
