Aging and free recall for objects located in space.

The free recall of objects located in space was examined in young and elderly respondents. The visual distinctiveness of the spatial context in which the stimulus objects were placed was varied systematically. Under conditions in which contextual cues were lacking (objects presented simply in a list format), or in which the context was visually bland (a two-dimensional, black-and-white map), the free-recall performance of elderly persons was significantly poorer than that of young adults. Under conditions in which visually distinctive cues were added to the spatial context (a colored map, a three-dimensional unpainted model, a three-dimensional painted model, or a large room), no difference in performance between young and elderly respondents was observed. Results support the hypothesis that visually distinctive cues produce greater depth of processing for elderly persons, facilitating free recall of objects located in space.

Memory for object locations in young and elderly adults.

The spatial memory of elderly and young adults was compared in two conditions: one in which common objects were displayed on a map, and one in which the objects were displayed in an actual environment (a large room) represented by the map. In the map condition, elderly adults had lower spatial memory scores than did young adults. In the room condition, however, the performance of elderly adults was not different from that of young adults. It was hypothesized that differences in the visual distinctiveness of the two contexts, map and room, were responsible for the interaction of age and task setting. An experiment using models of the map-room structures, models that differed in the visual distinctiveness of their components, confirmed this hypothesis.

Speed and accuracy of mental image rotation in young and elderly adults.

The mental image rotation abilities of young and elderly persons were examined in three conditions. Participants were asked to respond as quickly as possible, as accurately as possible, or to be both fast and accurate in responding. The accuracy performance of elderly adults was poorer in the speed condition than that of college-aged persons. In the accuracy and the speed/accuracy conditions, however, elderly participants responded as accurately as did younger participants, although the elderly individuals took longer on average to accomplish the image rotation tasks. The results of this study indicate that elderly persons may be more proficient at mental image rotation than has been supposed, particularly when the demand for speed in responding is tempered or eliminated.

Fading procedures and conditional discrimination in children.

A discrimination reversal task followed by a conditional discrimination problem was administered to children (age range 36 to 107 months). A fading procedure was used during the discrimination reversal training of some subjects and other subjects were trained by a traditional procedure. More subjects trained by the fading procedure performed without errors during training and more subjects in the traditional group solved the conditional discrimination problem.
