InSight

Insight is the understanding of a specific cause and effect in a specific context. The term insight can have several related meanings:

An insight that manifests itself suddenly, such as understanding how to solve a difficult problem, is sometimes called by the German word Aha-Erlebnis. The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany.

In psychology, insight occurs when a solution to a problem presents itself quickly and without warning. It is the sudden discovery of the correct solution following incorrect attempts based on trial and error. Solutions via Insight have been proven to be more accurate than non-insight solutions.

Insight was first studied by Gestalt Psychology, in the early part of the 20th century, during the search for an alternative to associationism and the associationistic view of learning. Some proposed potential mechanisms for insight include: suddenly seeing the problem in a new way, connecting the problem to another relevant problem/solution pair, releasing past experiences that are blocking the solution, or seeing problem in a larger, coherent context.

Generally, methodological approaches to the study of insight in the laboratory involve presenting participants with problems and puzzles that cannot be solved in a conventional or logical manner. Problems of insight commonly fall into three types.

The first type of problem forces participants to use objects in a way they are not accustomed to (thus, breaking their functional fixedness), like the "Duncker candle problem". In the "Duncker candle problem", individuals are given matches and a box of tacks and asked to find a way to attach a candle to the wall to light the room. The solution requires the participants to empty the box of tacks, set the candle inside the box, tack the box to the wall, and light the candle with the matches.

The second type of insight problem requires spatial ability to solve, like the "Nine-dot Problem". The famous "Nine-dot problem" requires participants to draw four lines, through nine dots, without picking their pencil up.

The third and final type of problem requires verbal ability to solve, like the Remote Associates Test (RAT). In the RAT, individuals must think of a word that connects three, seemingly unrelated, words. RAT are often used in experiments, because they can be solved both with and without insight.
