A binocular reading test

Abstract

There is reported here the construction of tests to aid in interpreting the interrelationship of eyedness, visual acuity, and reading ability. Using Robinson's technique of measuring reading ability for left, right, and both eyes (by means of material presented in a stereoscope) the author found a boy who read more poorly with his left eye, which had poorer visual acuity, and yet who tended to prefer using this eye. Tests were developed, using stereoscopic material, to determine which eye was being used most in binocular reading. The technique involves presenting material in which certain words are presented on only one side or the other. Examples of the passages used are presented.
