Details

This work investigated whether common, interfering or independent processes exist for adaptation to different kinds of distortions. Additionally, the influence of different sensory informations on the adaptive processes has been determined. Therefore subjects executed center-out reaching movements to different target locations without seeing their acting hand. Visual feedback about the hand position was given by a cursor. During different transfer experiments subjects were exposed to two different kinds of distortions which differed in its physical nature (visual distortion, mechanical distortion) and/or its kinematic coupling to the hand (position-dependent, velocity-dependent) or in the amount of the effect of an applied force (defined point of contact, no defined point of contact). For all experiments results showed positive transfer effects between the adaptation to the different distortions. Consequently, evidence against interfering or independent adaptive processes has been found. The pattern of transfer suggests that the adaptive processes completely or partially overlap depending on different factors like the kind of influence (beneficial or constraining) between the adaptation to different kinds of distortions and the amount of the effect of applied forces. In addition, it has been shown that the presence or dominance of different kinds of sensory modalities during adaptation to different kinds of distortions does not influence the type of adaptation processing.
