Localization of Brain Lesions by Flicker Perimetry: A Quantitative Method

Cross-validation of the Halstead-Reitan tests for brain damage.

“…The Halstead Flicker-Fusion test, part of the original battery, was not investigated in its original form, since subsequent work (Reitan, 1955b) has suggested that its validity is questionable. A more reliable measure of visual deficit based on flicker perception has been devised in our laboratories and is currently in use (Parsons, Chandler, Teed, & Haase, 1966;Parsons & Huse, 19S8;Vega, Parsons, & Chandler, 1966). The tests were administered by trained assistants supervised by the This document is copyrighted by the American Psychological Association or one of its allied publishers.…”

Neuropsychological changes in adolescents with insulin-dependent diabetes.

“…Critical flicker frequency. Because of evidence demonstrating that the visual flicker technique is sensitive to diffuse brain dysfunction (e.g., Daley, Swank, & Ellison, 1979;Parsons & Gottlieb, 1960), the critical flicker frequency threshold was determined for each subject by using, a modification of the method reported by Vega, Parsons, and Chandler (1966). Both foveal vision and the left and right upper quadrants of the peripheral visual fields were tested with the descending method-of-limits technique.…”
