Adaptation to displaced vision measured with three tests

Adaptation to displaced vision: a change in the central control of sensorimotor coordination.

In characterizing the changes that occur in sensorimotor coordination after viewing the prism-displaced image of the hand, four types of explanation can be advanced: visual, proprioceptive, motor, and sensorimotor. Each one predicts different consequences on different tests of coordination: reaching for visual targets, orienting head to hand, orienting eye to hand, and repositioning the hand in...

Allocation of attention and the locus of adaptation to displaced vision.

Experimental subjects were exposed to prism-induced visual displacement of a target whose location was correctly given by proprioceptive-kinesthetic information. Control subjects were exposed alternately to visual displacement or proprioceptive-kinesthetic location information. During the adaptation period, experimental subjects in the visual attention condition performed a localization task th...

ADAPTATION TO DISPLACED HEARING : A Non - Proprioceptive Change

Adaptation to rearranged ear-hand coordination, generated by exposure to an auditory tracking task entailing 30° of functional rotation of the interaural axis was explored using 12 Ss. The results show that sensorimotor alterations that follow such auditory rearrangement are confined to ear-hand responses and do not transfer intermodally to eye-hand coordinations. These findings fail to support...

Adaptation to Displaced and Delayed Visual Feedback from the Hand

S viewed an oscilloscope trace of a short bar which appeared at the position of his nonvisible right hand. The motion of the trace was equivalent to the movements of the hand, which were restricted to a frontal plane. The bar could be optically displaced by 20 diopter prisms, either to the left or right, and its motion could be made to lag behind that of the hand by 1 of 6 delay intervals rangi...
