Describe the difference between divergent and convergent thinking, and explain which one is involved in creativity.

Convergent thinking is the application of knowledge you already have to a clearly defined question. There is not much creativity involved, but more pulling information you already have stored in your mind and reciting it. Questions requiring convergent thinking include "what is 3 times 3?" and "Is a cat a mammal?"

Divergent thinking is the synthesis of new ideas, and involves solving a problem without already having the information. This type of thinking involves creativity. Problems include figuring out how to make your roommates couch fit through a door, or designing a rollercoaster in Rollercoaster Tycoon.

It's worth noting that creativity usually involves a bit of both thinking processes, since you usually have to draw from preexisting knowledge in order to solve an unfamiliar problem. 

What’s the question exactly? i’d love to assist! would you mind rephrasing it? : )
