  • Title: The role of color in the implicit memory performance of healthy older adults and individuals with Alzheimer's disease.
    Author: Lloyd-Jones TJ.
    Journal: Neuropsychology; 2005 Jan; 19(1):44-53. PubMed ID: 15656762.
    Abstract:
    Although the Alzheimer's disease (AD) patients in this study were severely impaired in recognition performance, their naming performance demonstrated normal priming across transformations in object color. This is evidence for preserved implicit shape-based memory performance in AD patients. For colored-object decision, healthy older adult control participants but not AD patients showed priming for new associations between previously encountered object shapes and colors. The author argues, on the basis of this colored object decision performance, that the deficits present in AD do not allow shape and color to be integrated to form a novel unitized representation that can be used to benefit cognitive performance.
