[Title] New Modes of Generalization in Perceptual Learning [Abstract] The learning of many visual perceptual tasks, such as motion discrimination, has been shown to be specific to the practiced stimulus, and new stimuli require re-learning from scratch [1-6]. This specificity, found in so many different tasks, supports the hypothesis that perceptual learning takes place in early visual cortical areas. In contrast, using a novel paradigm in motion discrimination where learning has been shown to be specific, we found generalization: We trained subjects to discriminate the directions of moving dots, and verified that learning does not transfer from the trained direction to a new one. However, by tracking the subjects' performance across time in the new direction, we found that their rate of learning doubled. Moreover, after mastering the task with an easy stimulus, subjects who had practiced briefly to discriminate the easy stimulus in a new direction generalized to a difficult stimulus in that direction. This generalization demanded both the mastering and the brief practice. Thus learning in motion discrimination always generalizes to new stimuli. Learning is manifested in various forms: acceleration of learning rate, indirect transfer, or direct transfer [7, 8]. These results challenge existing theories of perceptual learning, and suggest a more complex picture in which learning takes place at multiple levels. Learning in biological systems is of great importance. But while cognitive learning (or "problem solving") is abrupt and generalizes to analogous problems, we appear to acquire our perceptual skills gradually and specifically: human subjects cannot generalize a perceptual discrimination skill to solve similar problems with different attributes. For example, in a discrimination task as described in Fig. 1, a subject who is trained to discriminate motion directions between 43:5 ffi and 46:5 ffi cannot use this skill to discriminate 133:5 ffi from 136:5 ffi . 1 Such specificity supports the hypothesis that perceptual learning embodies neuronal modifications in the brain's stimulus-specific cortical areas (e.g., visual area MT) [1-6]. In contrast to previous results of specificity, we will show, in three experiments, that learning in motion discrimination always generalizes.
