The Aha! moment

The proverbial Aha! moment, or sudden insight, as typically experienced by creative practitioners, is a phenomenon that has been studied and theorised about by neuroscientists and cognitive psychologists for over a century. Most recent studies, however, show that insight is not a sudden flash that comes from nowhere. In fact, it is the result of the unconscious mind piecing together loosely connected bits of information stemming from prior knowledge and experiences and forming novel associations among them. That is, in contrast to analytical problem solving, which involves the use of a systematic process or logical reasoning to arrive at a solution to a problem, and where individuals can typically fully explain the steps taken to arrive at the solution, with insight, individuals cannot readily reconstruct the procedure followed to reach the solution..That is, problem solving by insight versus analysis are different in that creativity is not an insight moment although insight can produce creativity. The relationship, then, between insight and creativity is a controversial one. And so, the Aha! moments remain one of the most intriguing and unexplained processes of the human mind  Source: https://www.intechopen.com/chapters/65968
