A Muscular component in the inter-limb transfer of the kinesthetic spatial aftereffect

Abstract

The Muence of the muscular component involved in rotating the limb to its normal resting position on the inter-limb transfer of the kinesthetic spatial aftereffect was investigated in two experiments. In each case the kinesthetic task was that of judging the horizontal after the limb had been rotated through 20" and held in that position for 90 sec. The results showed that while relatively large intra-limb effects were produced in both experiments the magnitude of the inter-limb transfer was influenced by the return of the limb to its normal resting position. The muscular component was seen as relevant in explaining previous findings of inter-limb transfer.
