“…For example, Sekuler, Kahana, McLaughlin, Golomb, and Wingfield (2005) showed that young and older participants demonstrated equivalent short-term visual recognition memory, achieving equivalent proportions of correct old-new judgments, at each of three different, brief test delays. The present study adapted these basic methods to examine short-term temporal order memory with new samples of participants.…”

Increased difficulty with memory for recent events is a well-documented consequence of normal aging, but not all aspects of memory are equally affected. To compare the impact of aging on short-term recognition and temporal order memory, young and older adults were asked to identify the serial position that a probe item had occupied in a study set, or to judge that the probe was novel (had not been in the study set). Stimuli were compound sinusoidal gratings, which resist verbal description and rehearsal. With retention intervals of 1 or 4 seconds, young and older adults produced highly similar overall performance, serial position curves, and proportions of trials on which a correct recognition response was accompanied by an incorrect temporal order judgment. Temporal order errors, which occurred on about one quarter of trials, were traced to two factors: perceptual similarity between the wrongly identified study item and the correct item, and temporal similarity between the wrongly identified item and the correct one. Our results show that short-term visual temporal order memory is well-preserved in normal aging, and when temporal order errors do occur, they arise from similar causes for young and older people.

“…The ten older subjects, who were evenly split be-140 tween males and females, were drawn from a pool of independent living, active, healthy older adults. Previous studies with subjects from this pool, though not with the present subjects themselves, showed a striking preservation of visual memory, both for items and serial position (Sekuler,145 Kahana, McLaughlin, Golomb, & Wingfield, 2005;Sekuler, McLaughlin, Kahana, Wingfield, & Yotsumoto, in press). By selecting subjects from this pool we expected to reduce the likelihood that MOT results would be contaminated by general, age-related changes in memory per se.…”

Age-Related Changes in Attentional Tracking of Multiple Moving Objects

In a multiple object tracking (MOT) task, young and older adults attentively tracked a subset of ten identical, randomly moving disks for several seconds, and then tried to identify those disks that had comprised the subset. Young adults who habitually played video games performed significantly better than those who did not. Compared to young subjects (mean age = 20.6 years) with whom they were matched for video game experience, older subjects (mean age = 75.3 years ) showed much reduced ability to track multiple moving objects, particularly with faster movement or longer tracking times. Control measurements with stationary disks show that the age-related decline in MOT was not caused by a general change in memory per se. To generate an item-wise performance measure, we examined older subjects' proportion correct according to the serial order in which individual disks were identified. Correct identifications of target disks declined with the serial order in which targets were selected, suggesting that attentional tracking produced graded outcomes.Word count: 3470

“…Because the set of memoranda varies from one trial to the next, successful recognition performance on any trial requires access to episodic information, that is, information about the items seen on that trial. Systematic variation of perceptual differences among stimuli produces highly predictable changes in recognition performance (Zhou, Kahana, & Sekuler, 2004;Sekuler, Kahana, McLaughlin, Golomb, & Wingfield, 2005;Kahana, Zhou, Geller, & Sekuler, in press). These changes, in turn, support detailed quantitative accounts of recognition memory and intentional ignoring.…”

Does visual information enjoy automatic, obligate entry into memory or, after such information has been seen, can it still be actively excluded? To characterize the process by which visual information could be excluded from memory, we used Sternberg's recognition paradigm, measuring visual episodic memory for compound grating stimuli. Because recognition declines as additional study items enter memory, episodic recognition performance provides a sensitive index of memory's contents. Three experiments showed that an item occupying a fixed serial position in a series of study items could be intentionally excluded from memory. Additionally, exclusion does not depend upon low-level information such as stimulus spatial location, orientation or spatial frequency, and does not depend upon the precise timing of irrelevant information, which suggests that the exclusion process is triggered by some event during a trial. The results, interpreted within the framework of a summed similarity model for visual recognition, suggest that exclusion operates after considerable visual processing of the to-be-excluded item.
