摘要

The learning of the deployment of transient attention is an entirely new yet robust phenomenon. We found that it is mediated by a unique primitive short term memory system which learns features, not objects. Yet it is object centered and not retinotopic. This learning is graded, incremental and short lived. We also investigated longer term perceptual learning: very short naps during the afternoon can enhance perceptual learning dramatically, that in some cases beneficial effects are as good as a whole nights sleep. We suggest that for a nap to be beneficial it must contain both SWS and REM. In terms of a neurophysiological substrate, the learning must be occurring in the early visual areas because the effects are restricted to the specific visual quadrants stimulated. The other main focus of the work has been the role of learning of attentional deployment on motor behavior, in particular arm movements. There seems to be a direct coupling between the deployment of focal attention and action, the speed of motor activities is determined by the deployment of focal attention. Less expected, are results indicating that the planning and execution of motor actions are not separable. Decisions are often countermanded by mid%stream changes in motor actions with little cost in speed or accuracy indicating that the combined brain and motor plant is adept at parallel processing of simultaneous motor commands.
