Abstract

The role of allocentric cues on movement control was investigated in the present study. Pointing movements directed to the more distant vertex of closed and open configurations of the Müller-Lyer illusion, as well as to the vertex of control lines, were studied in four experimental conditions. In the first (full-vision condition) subjects saw both stimulus and their hand before and during movement, in the second (non-visual feedback condition) they saw the stimulus, but not their hand during movement. In the two remaining conditions (no-vision conditions) vision of the scene and the hand was precluded. Pointing was executed 0 sec (no vision 0 sec delay condition) or 5 sec (no-vision 5 sec delay condition) after the light was switched off. The Müller-Lyer illusion affected pointing kinematics with respect to the control lines. Subjects undershot and overshot the vertex location, respectively, of the closed and open configuration. Correspondingly, the entire kinematics were changed. The main result was, however, a gradually increasing effect of the perceptual illusion when pointing was executed from memory compared to the full-vision condition. These data are discussed according to the hypothesis that the system underlying visual perception in the allocentric frame of reference and that involved in motor action can functionally interact. The strength of this interaction depends upon the efficiency of the egocentric frame of reference by which motor actions are constructed.

      Where perception-action disassociations are reported, online feedback of the moving limb has been found with some illusions to fine tune the motor estimation of the target illusion to the correct size (Glover, 2002; Hughes et al., 2008). In the absence of this feedback, the motor estimate corresponds to the illusory effect (Aglioti et al., 1995; Gentilucci et al., 1996; Otto-de Haart et al., 1999). On stairs, vision is used in a feedforward manner to plan for approximately two to three steps ahead (Zietz and Hollands, 2009).

      However, verbalization was not found to provoke either a numerical magnitude- or an increased context-effect. This was somewhat surprising given that consciously controlled actions have been seen to increase reliance on allocentric information for localizing targets in studies with delay (Gentilucci, Chieffi, Daprati, Saetti, & Toni, 1996; Gentilucci, Daprati, Gangitano, & Toni, 1997; Olthuis, Van Der Kamp, & Caljouw, 2017; Rossetti, 1998). Poletiek (2001) argued that a major function of consciousness is hypothesis testing, comparing internal thoughts with external facts to engage with the environment (as cited by Masters, 2012).
