Jh. Ricker et al., VISUOPERCEPTUAL-SPATIAL ABILITY AND VISUAL MEMORY IN VASCULAR DEMENTIA AND DEMENTIA OF THE ALZHEIMER-TYPE, Neuropsychologia, 32(10), 1994, pp. 1287-1296
This study investigated the relationship between visuoperceptual abili
ty and visual memory in dementia. Twenty individuals with probable dem
entia of the Alzheimer type, 24 individuals with probable vascular dem
entia, and 20 healthy, elderly adults underwent neuropsychological eva
luation. Hierarchical multiple regression analyses suggested that perc
eptual organization skills contributed to a significant amount of the
variance in novel, but not famous, face recognition. This finding was
most robust in the clinical groups. Causality cannot be attributed fro
m this regression model. Results suggest, however, that visual process
ing deficits are more strongly related to the memory process at the ti
me of encoding rather than during recognition of remote information.
