Length of work periods in visual research

Abstract

"The present experiment was designed to investigate the use of relatively short work periods in one type of visual research. It appears that the length of work period that needs exploring ranges from 1½ to 10 minutes." Using the Tinker Speed of Reading Test, relative efficiency of speed of perception was individually assessed for 180 college sophomores under 5, 25, and 200 foot-candles of light. The only significant difference in reading speed was a decrement under 200 foot-candles for both 5- and 10-minute work periods. Glare effect is suggested.
