报告题目：Sensory, Cognitive and affective modulation of auditory  learning

报告摘要：Most perceptual skills improve with practice, providing a potential avenue  for restoration of sensory impairments and acquisition of perceptual expertise.  Conventionally, perceptual learning has been viewed as a result of refining or  rewiring of early sensory processing where individual stimulus features are  encoded, to be consistent with the prominent stimulus specificity of learning.  Here I present evidence that auditory learning are modulated by sensory,  cognitive, and affective manipulations. First, learning and transfer of an  auditory task can vary with slight changes in the training stimuli, indicating  that sensory input interacts with task demand to decide the learning mechanism.  Second, cognitive functions such as attention and working memory contribute to  auditory performance, and manipulations impacting these functions also impact  learning. Further, perceptual learning can benefit unselectively from activation  of the internal reward system. Activities that yield reward signals, such as  game play, can enhance learning of contiguous experiences even across  modalities. The results call for a view of perceptual learning as an interactive  process among sensory, cognitive, and affective systems. Illustrating this  interactive process will lead to a better understanding of brain plasticity as  well as development of more effective training regimens.
