The Simon Effect

The Simon Effect is a psychological phenomenon where people respond faster and more accurately when the location of a stimulus matches the location of their response, even if the location isn't relevant to the task. For example, if you’re asked to press a left button when you see a certain word, you’ll do so quicker if the word appears on the left side of your screen, compared to when it appears on the right. This effect highlights how our brain’s processing of spatial information can influence our reactions, even when that information is irrelevant to what we’re supposed to do.
