Colors in imagery and memory performance.

The present research investigated the effects of imaging in different colors on memory performance. Four groups of subjects were told to form an interactive image in a specific color for each of 30 word pairs. A fifth group was instructed to form an interactive image but received no color instruction, and a sixth group was told to form a non-interactive image and received no color instruction. Analysis showed the five interactive groups differed significantly from the non-interactive group but there were no reliable differences among the different color conditions. These results contradict a prediction derived from Switras' 1977 study of color in imagery.
