ABSTRACT
In one sense everything I have talked about so far can be thought of as problem-solving. Deciding how to categorize and respond to an object poses a problem. If there really is a panther in the garden something has to be done about it pretty quickly. Reading books and talking to people involve problems of interpretation. It is true that IQ tests and logical puzzles are the problems most commonly used in psychological research. But in a wider sense it could be claimed that humans are never stirred into action unless they are faced with a problem of some kind.
