Visual short-term memory, response delay, and age.

Recall and recognition memory performance of 12 young (M = 19 yr.) and 12 older (M = 72 yr.) females was studied in relation to response delay (5, 25, and 125 sec.) and stimulus complexity (6.1 and 13.7 bits of information). The subjects were matched on verbal IQ, visual acuity, and educational levels. Stimuli were abstract, black and white, 4 X 4 square matrices. Age-related decrements in memory performance were associated with stimulus complexity but not with response delay. Older subjects also reported experiencing encoding difficulties during the registration phase. The results were discussed with reference to the locus of age-related decrements in visual short-term memory.

Visual short-term memory, age, and imaging ability.

Visual short-term memory of young and older adults was studied in relation to imaging ability. Both recall and recognition memory tasks were used and additional variables included stimulus complexity and response delay (recognition tasks) and stimulus complexity and visual masking (recall tasks). Young and older participants were matched on visual discrimination, verbal intelligence, and imaging ability. Stimuli consisted of abstract visual patterns. Age-related decrements in recognition and recall were observed but performance was related to imaging ability only with recall tasks and only for older adults. The results were discussed with reference to mediational strategies and locus of occurrence of age-related decrements in short-term memory.

Visual short-term memory and aging.

Short-term memory (STM) functioning of young and older adults was studied in two experiments in which recall and recognition tasks were used. The stimuli consisted of simple and complex visual patterns which were subject paced (Exp. I) or paced (Exp. II). Sex and response delay were the other independent variables. Age-related decrements in visual STM were observed. They interacted in a complex manner with the other variables suggesting age-related deficits at the encoding and post-encoding but not the retrieval phases. The results were discussed with reference to the locus of age related STM deficits.
