A tachistoscope is a device that provides the researcher timing control over a visual stimulus by exposing images to the eye for a very brief measured period of time. In marketing research, the visual stimulus is often a specific advertisement.[1]

It can be used to measure visual perception, memory, and learning, among others.

Tachistoscope training, or flash recognition training (FRT) is a technique designed to improve the recall of visual information.[2]
