Memories may skew visual perception (Sona replacement)

A recent study from Vanderbilt University suggests that recalling memories from the past can alter your current visual perception. An experiment was done participants were shown a random pattern of dots and were asked to remember the direction in which the dots were moving. They were then were shown a second pattern of moving dots. They were asked to report on the direction of second dots’ movement. Subjects said that the second dots movement was greater and influenced by the patterns they previously saw. If they had seen dots moving in one direction and later shown dots moving in the opposite direction then opposite direction dots seemed much more dramatic even if it was the same pattern only reversed. “Our findings provide compelling evidence that visual working memory representations directly interact with the same neural mechanisms involved in processing basic sensory events,”
