为什么老年人在他们的凝视模式中表现出积极的偏好，优先看积极的东西，远离一些消极的刺激？目前的研究调查了老年人对积极（快乐）刺激和远离消极（愤怒）刺激的偏好固定的时间过程，以辨别这种模式是否与认知控制或简化处理帐户更一致。积极的偏好在老年人中被发现出现只有500毫秒后，刺激发作和线性增加，随着时间的推移，这个时间过程是一致的认知控制帐户。
When and why do older adults show positive preferences in their gaze patterns, looking preferentially toward positive and away from some negative stimuli? The current study investigated the time course of older adults' preferential fixation toward positive (happy) stimuli and away from negative (angry) stimuli to discern whether such patterns are more consistent with cognitive control or with simplified processing accounts of their origins. Positive preferences in older adults were found to emerge only 500 ms and later after stimulus onset and increased linearly over time; this time course is consistent with a cognitive control account.
