"Age-related deficits in generation and manipulation of mental images: I. The role of sensorimotor speed and working memory": Correction to Briggs et al. (1999).

Reports several errors in the original article by S. Briggs, N. Raz and W. Marks (Psychology & Aging, 1999 (Sep.), Vol.14(3), 427–435). None of the errors alter the conclusions of the article. (The following abstract of this article originally appeared in record 1999-11243-006). The authors investigated age-related slowing of information processing in mental imagery tasks. Eighty-five healthy adults (ages 18 to 77) performed a visual, sensorimotor, reaction-time task; a visual-perceptual choice reaction task; and 3 mental imagery tasks that varied in apparent difficulty and involved stimuli at 2 levels of graphic complexity. Age was associated with prolongation of response time across all tasks and both levels of stimulus complexity. Accuracy of response was adversely affected by increase in stimulus complexity in all tasks, whereas it was negatively related to age only on the tasks with substantial mental imagery requirements. Slowing of information processing and reduction in accuracy were mediated by declines in working memory but not by decrease of sensorimotor speed.
