Ternus displayの運動知覚における刺激要素の空間周波数の効果

概要

A Ternus display is a type of apparent motion stimulus in which the perceived motion of the constituent elements is bistable; two types of apparent motion are sensed depending on the temporal parameter (the inter-frame interval) of the stimulus sequence. This study employs Gabor patches as elements of the Ternus display to investigate the effect of an element's spatial frequencies on the apparent motion. The perceived motion strongly depends on the location of the element with a lower spatial frequency for a Ternus display composed of patches with different spatial frequencies. The results are discussed in terms of the interactions of the motion signals between the elements.
