Abstract

Earlier studies into perceptual learning showed considerable individual differences: Individuals differ in their ability to attune to a specifying variable. A possible source of these individual differences is between-subject variation in the capacity to benefit from feedback. While this hypothesis was postulated earlier, it lacked a critical test. The aim of the present experiment was to provide such a test. To do so, we trained two groups of participants in length perception by dynamic touch in two different learning environments. In one environment it was easier for a perceiver to separate the perceptual error due to noise in the perceptual system from the error based on the detection of a nonspecifying variable. This separation was more difficult to make in the second learning environment. We found that the group that trained in the easy environment outperformed the group in the difficult environment. Thus we conclude that individuals indeed differ in the capacity to benefit from feedback. The implications of these results for some recent debates in the ecological approach to perceptual learning are discussed.
