New insight into 'aha' memories
Date:3/31/2011

When we suddenly get the answer to a riddle or understand the solution to a problem, we can practically feel the light bulb click on in our head. But what happens after the 'Aha!' moment? Why do the things we learn through sudden insight tend to stick in our memory?

'Much of memory research involves repetitive, rote learning,' says Kelly Ludmer, a research student in the group of Prof. Yadin Dudai of the Institute's Neurobiology Department, 'but in fact, we regularly absorb large blocks of information in the blink of an eye and remember things quite well from single events. Insight is an example of a one-time event that is often well-preserved in memory.'

To investigate how lessons we gain from insight get embedded in our long-term memory, Ludmer, Dudai and Prof. Nava Rubin of New York University designed a test with 'camouflage images' - photographs that had been systematically degraded until they resembled inkblots. When volunteers first viewed the images, they were hard pressed to identify them. But after the camouflage was switched with the original, undoctored picture for a second, the subjects experienced an 'Aha!' moment - the image now popped out clearly even in the degraded image. Their perceptions, says Ludmer, underwent a sudden change - just as a flash of insight instantly shifts our world view. To tax their memory of the insightful moment, participants were asked to repeat the exercise with dozens of different images and, in a later repeat session, they were given only the camouflaged images (together with some they hadn't seen before) to identify.

The team found that some of the memories disappeared over time, but the ones that made it past a week were likely to remain. All in all, about half of all the learned 'insights' seemed to be consolidated in the subjects' memories.

To reveal what occurs in the brain at the moment of insight, the initial viewing session was conducted in a functional MRI (fMRI) scanner
