According to Wertheimer, reaching an understanding involves many aspects of learners, such as their emotions, attitudes, and perceptions, as well as their intellects. In gaining insight into the solution to a problem, a student need not—in fact, should not—be logical. Rather, the student should cognitively arrange and rearrange the components of the problem until a solution based on understanding is reached. Exactly how this process is done will vary from student to student.
