Insight into problem solving

The three major components of thought are images, concepts, and language. Directed thinking is aimed at solving a particular problem or reaching a certain goal. Logical thinking which adheres to rules of reasoning is one method of accomplishing this. Logical thinking often takes the form of a series of statements, which, if accurate and combined correctly, lead to a logical conclusion.
Various factors can affect problem solving. Anxiety, anger, and frustration may make a problem more difficult to solve, or they may increase efficiency in working out a solution to a problem. The way you are used to perceiving certain situations as a result of experience can also affect the way the problem is approached.
Not all forms of problem solving take place by means of thought especially in the fields if invention and science, where a kind of thinking is often necessary that gets at the solution to a problem by a path that is different from purely directed thinking. This sort of thinking is called creative, is to some extent directed thinking. What is different about this kind of problem solving is insight, a seemingly arbitrary flash that presents out of the blue, in the form of a solution to the problem.
This type of thinking is explained in terms of inspiration. Here first all the necessary preparation for a new work is carried out but the solution is not in sight. This is followed by a period of incubation. Now the individual is not actively or consciously thinking about the problem. However in the subconscious mind the process of problem solving is going on. It takes you to the third stage of illumination, where the seemingly spontaneous appearance of the creative insight or solution is found. In the last stage verification, the solution is tested against the criteria of the problem.
