Abstract
A relationship between binocularity and read-ing was developed in terms of the recognition function in reading. A sample of 162 fifth grade students in a parochial school were divided into good, average, and poor readers on the basis of a standardized reading test. All subjects were given an oral reading test under a control condition and two conditions of binocular disturbance. The two experimental conditions differed in the location of an aniseikonic lens, one on the right eye the other on the left. Change in the number of errors from the control condition was used as a measure of disturbance of reading performance. The results offered evidence for a relationship between binocular instabilities and reading performance.
