  • Title: How color enhances visual memory for natural scenes.
    Author: Spence I, Wong P, Rusan M, Rastegar N.
    Journal: Psychol Sci; 2006 Jan; 17(1):1-6. PubMed ID: 16371136.
    Abstract:
    We offer a framework for understanding how color operates to improve visual memory for images of the natural environment, and we present an extensive data set that quantifies the contribution of color in the encoding and recognition phases. Using a continuous recognition task with colored and monochrome gray-scale images of natural scenes at short exposure durations, we found that color enhances recognition memory by conferring an advantage during encoding and by strengthening the encoding-specificity effect. Furthermore, because the pattern of performance was similar at all exposure durations, and because form and color are processed in different areas of cortex, the results imply that color must be bound as an integral part of the representation at the earliest stages of processing.
