Effect of contextual organization on spatial memory of middle-aged and older women.

Examined the memory performance of 20 women aged 31–59 yrs and 20 aged 65–85. Ss reconstructed spatial arrays, replacing miniature objects in either a contextually organized panorama or a noncontextually organized bank of cubicles. Performance of the middle-aged Ss did not differ between the 2 tasks. Older Ss performed as well as middle-aged Ss in the panorama task, but in the cubicles task their scores were lower than in the panorama task and lower than those of the younger Ss in the cubicles task. Results support the conclusion that in a task that allows the use of existing contextual organization as a memory aid, age differences in memory performance disappear. Age differences may be limited to tasks that remove previously learned relationships between items (as in recall of lists of unrelated words), requiring Ss to invent an organizational structure to facilitate recall. Though such tasks predominate in research, they probably do not represent the memory problems met in everyday life, especially by older adults.
