"Sudden insight is associated with shutting out visual inputs" by Carola Salvi, Emanuela Bricolo, Steven L. Franconeri, John Kounios, &Mark Beeman

Summary

This research paper investigates the link between attention and insight problem-solving. The authors directly measured eye movements and blinks—indicators of attention—while participants solved visual problems, finding that increased blinking and fewer fixations (looking away from the problem) preceded solutions achieved through insight, contrasting with decreased blinking and more fixations before analytically solved problems. This difference was observed both before problem presentation and immediately prior to solution, supporting the idea that insight involves shifting attention inward, away from external visual stimuli. The study's purpose is to provide direct evidence, through observable eye behaviour, for the previously indirectly observed association between internal attention and the "Aha!" moment of insight.
