ABSTRACT
This chapter looks at general observations about the ideation process. It provides some of the ideas of those who think that creativity is best explained by the neuro-physiological functioning of the brain. Whole-brain and two-brain theories exemplify this approach. The chapter shows that a connection between the neuro-physiological functioning of the brain and the cognitive theory of creative problem solving. It also looks at the notion of divergent and convergent thinking, and suggests that the conditions under which ideation takes place are very important. The chapter describes some of the ideas which pertain to the subject in the hope of providing some background against which to appreciate the various steps of the creative problem-solving process. A. Cropley added various stages to Graham Wallas' model. He argued that there was a need to recognise or 'find' a problem about which the person can be creative. According to schema theory, schemas influence the way that new information is processed.
