Prism adaptation to dynamic events.
In the present study, we explored adaptation to prism-displaced dynamic and static events under conditions of minimal information. Many of our interactions with the world are dynamic and involve reaching for or intercepting moving objects. The consequences (or feedback) of those interactions entail the presence or absence of physical contact with the moving objects. In this study, humans learne...
متن کاملAttention and prism adaptation.
For both lateral displacement and rotation of the visual field, visual adaptation was reduced when subjects were required to perform a secondary cognitive task simultaneously with the primary exposure task of walking about hallways. Interference appeared to be independent of walking rate and occurred when the cognitive task was either mental imagery or mental arithmetic. A tentative model is pr...
متن کاملPrism adaptation and 1 Running head: PRISM ADAPTATION AND NEGLECT Prism Adaptation and Hemispatial Neglect: Notes Toward Understanding
Theory and data from normal prism adaptation are applied toward understanding the ameliorating effects of prism adaptation for left hemispatial neglect patients. The composite nature of the egocentric (noetic) reference frame suggests that the therapeutic value of prism adaptation might be enhanced if a prism adaptation task were selected that produces spatial realignment in the patient’s dysfu...
متن کاملGeneralization of prism adaptation.
Prism exposure produces 2 kinds of adaptive response. Recalibration is ordinary strategic remapping of spatially coded movement commands to rapidly reduce performance error. Realignment is the extraordinary process of transforming spatial maps to bring the origins of coordinate systems into correspondence. Realignment occurs when spatial discordance signals noncorrespondence between spatial map...
متن کاملAsymmetric generalization in adaptation to target displacement errors in humans and in a neural network model.
Different error signals can induce sensorimotor adaptation during visually guided reaching, possibly evoking different neural adaptation mechanisms. Here we investigate reach adaptation induced by visual target errors without perturbing the actual or sensed hand position. We analyzed the spatial generalization of adaptation to target error to compare it with other known generalization patterns ...
