Attention value as a function of illuminant color change

Abstract

A 16-dial panel was tested with a check-reading task (to detect deviations) for the effect of illumination changes to aid detection of errors. In one situation (R), from 1 through 8 error dials were presented under constant red illumination. In the other situation (RG) error dials were accompanied by a change in illuminant from red to green. "(a) Differences between response times and also variability of response under the R and RG situations were significant; (b) three times as many errors were committed under the R situation; (c) no significant sex differences were present under either the R or RG situation."
