Research using eye movement monitoring suggests that recapitulating the pattern of eye movements made during stimulus encoding at subsequent retrieval supports memory by reinstating the spatial layout of the encoded stimulus. In the present study, the authors investigated whether recapitulation of encoding fixations during a poststudy, stimulus-free delay period-an effect that has been previously linked to memory maintenance in younger adults-can support mnemonic performance in older adults. Older adults showed greater delay-period fixation reinstatement than younger adults, and this reinstatement supported age-equivalent performance on a subsequent visuospatial-memory-based change detection task, whereas in younger adults, the performance-enhancing effects of fixation reinstatement increased with task difficulty. Taken together, these results suggest that fixation reinstatement might reflect a compensatory response to increased cognitive load. The present findings provide novel evidence of compensatory fixation reinstatement in older adults and demonstrate the utility of eye movement monitoring for aging and memory research.

使用眼动监测的研究表明，在后续检索过程中重现刺激编码期间的眼动模式，通过恢复编码刺激的空间布局来支持记忆。在本研究中，作者调查了在学习后无刺激延迟期重现编码注视——这种效应先前已被认为与年轻人的记忆维持有关——是否能支持老年人的记忆表现。与年轻人相比，老年人在延迟期的注视恢复程度更高，并且这种恢复在随后基于视觉空间记忆的变化检测任务中支持了与年龄相当的表现，而在年轻人中，注视恢复对表现的增强作用随着任务难度的增加而增加。综合来看，这些结果表明注视恢复可能反映了对认知负荷增加的一种补偿反应。本研究结果为老年人的补偿性注视恢复提供了新证据，并证明了眼动监测在衰老和记忆研究中的实用性。（PsycINFO数据库记录）
