Perception of a Reverse Perspective Illusion

Optical illusions of depth, size, and shape occur when an image utilizes the visual system\u27s function of size-distance invariance, resulting in the misperception of a dimension of the image. Reverse perspective illusions exploit size-distance invariance; the tendency to base an object\u27s perceived size on its perceived distance, and vice versa; by illustrating things that are farther away from the viewing plane as larger and objects that are closer to the viewing plane as smaller. This technique effectively makes a convex 3-dimensional object appear concaved. We will describe the sensory and perceptual processes involved in viewing a reverse perspective illusion through the visual system, including the neural pathways utilized in the visual brain. In addition, we will explain a reverse perspective illusion that we created in terms of static monocular depth cues, attention and awareness, and color perception
