Coming back to the process, when the person is trying to generate alternative ideas and trying to view the problem or task from an unusual perspective, there may be a feeling of getting stuck. One may even get disgusted with failure and may leave the problem or the task for sometime. This is the stage of incubation. Research shows that creative ideas may not occur immediately during incubation when the individual is not consciously thinking about the problem but seeking relaxation from conscious effort. They may occur or strike when a person is doing something else, for example, going to sleep, waking up, taking a bath or just walking along. Followed by incubation is the stage of illumination - the ‘Aha’! or ‘I have found it’ experience, the moment we normally associate with emergence of creative ideas. There usually is, a feeling of excitement, even satisfaction, of having found a creative idea. Last is the stage of verification when the worth or appropriateness of ideas or solutions are tested and judged. Here, convergent thinking plays its role in selecting the appropriate idea or solution that works.
