Selgus

Selgus is a term used in cognitive science to describe the subjective experience of insight during problem solving—the moment when a solution or meaningful pattern becomes suddenly clear. In this sense, selgus encompasses both the cognitive restructuring that yields a solution and the felt certainty that the solution is correct. The term has been used in educational psychology to distinguish sudden insights from gradual problem-solving.

Selgus typically occurs after a period of impasse or incubation, though it can arise during active work. It is often described as an abrupt, coherent realization accompanied by a positive affect and increased confidence. Because selgus is inherently subjective, researchers study it using self-reports, think-aloud protocols, and experiments comparing problems solved with and without reported selgus.

Typical domains include mathematics, verbal puzzles, and perceptual tasks, but selgus has been observed across many cognitive domains. Some theories tie selgus to restructuring of problem representation, while others emphasize distributed unconscious processing that culminates in conscious awareness.

In research, selgus is discussed alongside concepts such as insight, the Aha! moment, and creative problem solving. Critics note that the reliance on self-reported experience makes it difficult to measure objectively, and that the term may conflate diverse cognitive phenomena.

This entry uses selgus as a neutral technical term for a commonplace cognitive experience, not tied to a specific discipline and open to interpretation as a phenomenon in cognitive science.
