AnnotationThe relationships between age-related differences in specific regions of the cerebral cortex and performance on visual perception and mental imagery tasks were investigated in this study. Sixty adults aged between 19-77 performed a series of visual-spatial mental imagery tasks that varied in apparent difficulty and involved stimuli of varying graphic complexity. Findings suggest that age-related deficits in performance on mental imagery tasks may stem in part from age-related shrinkage of the prefrontal cortex and age-related declines in working memory but not from age-related slowing of sensorimotor reaction time.
