Abstract

We examined the asymmetric responses between the detection of motion toward and away from the observer with expanding/contracting shaded circles. Our experiment followed visual search paradigm. In our experiment, targets and distractors were defined by expanding (or contracting) convex/concave circles. Expanding or contracting convex circles can be perceived as spheres moving in depth. However, Expanding or contracting concave circles cannot be perceived as objects moving in depth. Results suggested that the human visual system is more sensitive to expanding convex circles (which create the impression of approaching objects) than others.
