Outflow and inflow in movement duplication

Abstract

Thirty Ss were assigned randomly to one of three conditions of blindfolded movement duplication: (1) constrained active movement (the E determined the end point of the S's movement), (2) unconstrained active movement, and (3) passive movement. Ss' absolute accuracy of duplication of the three conditions was compared. Significant differences were observed between the three conditions, though there was no significant difference between Conditions 1 and 3. The results are discuased in terms of "outflow" and "inflow" models of kinesthesis, and it is argued that some support is given to the outflow model. © 1972 Psychonomic Society, Inc.
