Tachistoscope Principle - Photographic Memory Training Using Flash Cards

Tachistoscope Instrument

Speed Reading and Photographic Memory training flash cards go back as far as the late 1930s. This is possible with the invention of the tachistoscope. You will notice the similarity of this right brain training method and theory with the right brain education/training for babies and toddlers.


What is a tachistoscope?

This device flashes a series of images on to a screen at a rapid speed to test visual perception, memory, and learning. It uses a slide projector equipped with a mechanical shutter system like a camera.

It is capable of projecting "flashcard" images as fast as 2 seconds to 0.01 seconds per duration.


How was this device used?

Tachistoscopic training was done during the World War 2 era. Samuel Renshaw (1892 - 1981) who was an Amerian psychologist, whose work became famous when he taught sailors and the Arm Forces to identify enemy aircraft in a split second.

The technique involves showing flashcard images of planes (a few hundredths of a second per image) they have to recognise on to a screen.

The training was known as the "Renshaw Training System for Aircraft and Ship Recognition".

Upon completion of the program, officers could identify more types of planes and ships with greater accuracy and with faster recognition time.


Tachistoscopic training is also known as FRT (Flash Recognition Training). Today FRT program is being used in the training of military and law enforcement professionals.


Based on the Tachistoscope Principle training method, where accurate visual and rapid speed is presented, the brain is able to recognise the image and is embedded in the subconscious mind of the child. The child is then able to recall the information from his subconscious mind and learning will be easy for the child.


In right brain education, accuracy and speed are vital as the right brain works faster than the left brain. The left brain works with analytical skill and logic while the right brain does not.
