Abstract
A debate exists regarding the relative processing level of cyclopean-defined motion in the visual system. Some authors have attributed the processing of cyclopean-defined motion to stages in the visual system that enact similar algorithms of motion computation to luminance-defined motion; whereas, other authors attribute the processing of cyclopean defined motion to cognitive processes that track stimuli features. Thus, the purpose of this study was to provide evidence that bears upon the debate regarding the relative processing stage of cyclopean motion. To explore this debate we utilized an action capture paradigm. Action capture refers to the possible influence of bodily movements on visual perception. In this study, we used bi-directional hand movements as a possible bias for the perception of motion direction in an ambiguous apparent motion display. Thus, observers (N = 60) executed (Experiments 1 and 2) or planned (Experiment 3) directional (i.e. horizontal, vertical, or none) hand movements while viewing either luminance- or cyclopean-defined apparent motion. It was predicted that if cyclopean motion is processed at a relatively higher stage in the visual stream, then cyclopean motion processing would be more susceptible to the possible influence of action capture than luminance motion processing. However, if cyclopean and luminance motion processing are both processed at similar stages in the visual stream, then cyclopean and luminance motion processing would be equally susceptible to the possible influence of action capture. The results of this investigation showed that directional hand movements could significantly bias the perceived direction of motion in apparent motion displays; however, this bias was no different for luminance and cyclopean defined apparent motion. Thus, we found no evidence that suggests cyclopean motion processing occurs at relatively higher levels of the visual stream where feature tracking may occur.
