Response time as an indicator of color deficiency

Abstract

Using 136 college students as subjects, response time measures to 15 selected plates of the AO pseudo-isochromatic test were secured by use of .01 sec. chronoscope connected to a voice key. Error scores were used to classify 110 subjects as normal, and mean response times between normal and defective groups were significantly different. It was concluded that response times could be used to separate color defective individuals from color normal individuals. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
