在这项研究中，年龄相关的差异，在视觉信息的选择进行了调查。两组年轻和年长的受试者进行集中和分散注意力（即，视觉搜索）任务。在集中注意任务中，中央呈现的目标字母两侧可能是兼容或不兼容的噪音字母。在视觉搜索任务中，目标可以被暗示或不被暗示，目标位置可以与响应的手在空间上兼容或不兼容。P3潜伏期，偏侧准备电位，肌电图和反应时间被用来检测可能的年龄相关的差异，在选择性处理信息的刺激和响应相关的过程中的时间。在集中注意力的任务，老年人的表现表现出更大的干扰不兼容的侧翼比年轻的受试者，因为更强的反应竞争所造成的部分激活不正确的反应通道的不兼容的侧翼。没有证据表明，具体的年龄相关的差异，在视觉搜索的效率在一个分散注意力的任务。此外，在这两项任务中，年轻的受试者表现出较早的开始响应执行（在肌电图）相对于发病的反应准备（偏侧准备电位）和较高的百分比不正确的肌电图活动比老年受试者。
In this study, age-related differences in the selection of visual information were investigated. Two groups of younger and older subjects performed focused- and divided-attention (i.e., visual search) tasks. In the focused-attention task, centrally presented target letters could be flanked by compatible or incompatible noise letters. In the visual-search task, targets could be cued or uncued, and target locations could be spatially compatible or incompatible with the responding hand. P3 latency, lateralized readiness potentials, the electromyogram, and reaction times were used to detect possible age-related differences in the timing of stimulus- and response-related processes during selective processing of information. In the focused-attention task, performance of older subjects showed greater interference by incompatible flankers than did that of younger subjects because of stronger response competition caused by partial activation of the incorrect response channel by the incompatible flankers. No evidence was found of specific age-related differences in the efficiency of visual search in a divided-attention task. Furthermore, in both tasks, younger subjects showed an earlier start of response execution (in the electromyogram) relative to the onset of response preparation (lateralized readiness potential) and a higher percentage of incorrect electromyographic activity than did older subjects.
