In order to solve an insight problem, you have to see the problem in a novel way. Insight is a sudden understanding of a problem or a strategy that aids in solving that problem. Usually, this involves conceptualizing the problem in a completely new way. Although insights might feel like they are sudden, they are often the result of prior thought and effort. While insight can be involved in solving well-structured problems, it is more often associated with ill-structured problems. There are several views on insight:
The Nothing-Special View: Insight is merely an extension of ordinary perceiving, recognizing, learning, and conceiving. Insights are significant products of ordinary thinking.
The Neo-Gestaltist View: Insight problem solvers show poor ability to predict their success. Problem-solvers do not show increase in feelings of "warmth" as they draw nearer to a solution of an insight problem. This supports the Gestaltist view that there is something special about insightful problem solving, as opposed to noninsightful, routine problem solving.
The Three-Process View: There are three different kinds of insights. (1) Selective-encoding insights involve distinguishing relevant from irrelevant information. (2) Selective-comparison insights involve novel perceptions of how new information relates to old information. (3) Selective-combination insights involve taking selectively encoded and compared bits of relevant information and combining them in a novel way.
When people solve, or attempt to solve an insight puzzle, they experience a common phenomenology, that is, a set of behavioural properties that accompany problem-solving activity (for a useful edited review of insight problems and their phenomenology, see Sternberg & Davidson, 1995). Other kinds of puzzle, such as the Tower of Hanoi, an example of a transformation problem, tend not to yield these phenomena. The phenomena may include:
Impasse: An individual reaches a point where he or she simply appears to run out of ideas of new things to try that might solve a problem.
Fixation: An individual repeats the same type of solution attempt again and again, even when they see that it does not seem to lead to solution.
Incubation: A pause or gap between attempts to solve a problem can sometimes appear to aid the finding of a solution, as if one is clearing the mind of faulty ideas.
The 'Aha' experience: The solutions to some insight problems can seem to appear from nowhere, like a Eureka moment.
