Vigilance Performance When Using Colour on Electronic Displays

Abstract

An experiment was conducted to examine the influence of colour in CRT displays on vigilance decrement. In three independent groups, each of 8 subjects, subjects had to monitor an achromatic display, a colour display, and an achromatic display with secondary task over 150 min. The results lead to the conclusion that the use of colour in electronic displays prevents vigilance decrement in comparison to achromatic displays.
