Psychology of computer use: IV. Effects of video display units on fundamental visual processes: temporal resolution.
Measures of two-pulse resolution (2PR) using foveally and peripherally viewed targets were obtained before and after reading videotext and print. Three pulse durations (25, 250, and 300 msec.) were used. The results showed that (a) 2PR on the fovea is about a fourth of that on the periphery, (b) peripheral 2PR increases following reading videotext, and (c) no appreciable effects occur following reading print.
