使用冲突适应效应（CAE）检查了视觉选择性认知控制的年龄相关变化。CAE反映了增加的刺激相容性的影响，低水平的冲突频率内块的审判。年轻人（n= 20）和老年人（n= 20）接受了埃里克森型侧翼任务，涉及兼容（例如， “44444”）或不兼容（例如，“44644”）阵列呈现给左或右视野（VF）。参与者识别数组的中心数字。冲突（不相容）试验的相对频率随VF的变化而变化。还操纵了试验区组中冲突较多的VF和冲突较少的VF条件的呈现顺序。结果表明，在第一组试验区组中，两个年龄组都出现了基于位置的CAE，而在最后一组试验区组中，基于位置的CAE仅出现在年轻成人中。这些结果表明，与情境依赖性认知控制相关的认知灵活性随着年龄的增长而减少。
Age‐related change in cognitive control for visual selectivity was examined using a conflict adaptation effect (CAE). The CAE reflects an increased stimulus compatibility effect for low levels of conflict frequency within blocks of trials. Younger (n= 20) and elderly (n= 20) adults received an Eriksen‐type flanker task involving compatible (e.g., “44444”) or incompatible (e.g., “44644”) arrays presented to either the left or right visual field (VF). The participants identified the central digit of an array. Relative frequency of conflict (incompatible) trials varied as a function of the VF. Also manipulated was the presentation order of more‐conflict VF and less‐conflict VF conditions over trial blocks. The results showed that a location‐based CAE appeared for both age groups in the first set of trial blocks, whereas in the final set of trial blocks the location‐based CAE appeared only for the younger adults. These results suggested that cognitive flexibility related to context‐dependent cognitive control diminishes with age.
