Question

When light from a flashlight is moved quickly back and forth on a wall in a darkened room, it can appear to observers that there is a trail of light moving across the wall, even though physically the light is only in one place at any given time. This experience is an effect of memory that occurs because ofa. a visual delay effect.b. echoic memory.c. persistence of vision.d. top-down processing.

Answer 1

The correct answer would be option C, Persistence of Vision.

This experience is an effect of memory that occurs because of Persistence of Vision.

Explanation:

Persistence of Vision is basically an optical illusion, an illusion observed by eyes. When the stimulus that produces the visual image has been removed, that visual image is retained by the eye for a very short period of time. It means that an illusion is created which is perceived by the human eyes.

So when a light from flashlight is moved quickly back and forth on a wall in a darkened room, it appears that a trail of light is moving across the wall, while we all know that light produced through a flashlight is only a small circle, so when light moves back and forth, it gives an optical illusion which is basically the visual image of the light retained by the eyes for a short period of time.
