17. Thinking
J. P. Guilford:
Convergent production - generation of logical conclusions from given information, where emphasis is upon achieving unique or conventionally best outcomes. It is likely that given (cue) information fully determines the outcome as in mathematics and logic.
Divergent production - generation of logical alternatives from given information, where emphasis is upon variety, quantity, and relevance of output from the same source.
