The effects of backgroup color on short-term memory

12 May 1987


Twenty college students were tested for the effects of background color on short-term memory using a serial-recall task. Subjects were tested using a Commodore computer/monitor. Nine black digits were presented on either a red, green, or blue screen for ten seconds. The subjects then re-entered the numbers using the computer keyboard. Scores were determined by counting the number of correct digits in the correct order that were entered as compared to those in the presentation. Ten trials of each color were preformed. Statistical analysis showed that there was no significant effect on the number of digits recalled between the different colors. Subjectively, though, there was a preference for the blue background and a dislike for the red background .
