Emotions affect temporal information processing in the low-frequency time window of a few seconds, but little is known about their effect in the high-frequency domain of some tens of milliseconds. The present study aims to investigate whether negative and positive emotional states influence the ability to discriminate the temporal order of visual stimuli, and whether gender plays a role in temporal processing. Due to the hemispheric lateralization of emotion, a hemispheric asymmetry between the left and the right visual field might be expected. Using a block design, subjects were primed with neutral, negative and positive emotional pictures before performing temporal order judgment tasks. Results showed that male subjects exhibited similarly reduced order thresholds under negative and positive emotional states, while female subjects demonstrated increased threshold under positive emotional state and reduced threshold under negative emotional state. Besides, emotions influenced female subjects more intensely than male subjects, and no hemispheric lateralization was observed. These observations indicate an influence of emotional states on temporal order processing of visual stimuli, and they suggest a gender difference, which is possibly associated with a different emotional stability.
情绪会影响几秒钟的低频时间窗口内的时间信息处理，但对于它们在几十毫秒的高频领域中的影响却知之甚少。本研究旨在调查消极和积极情绪状态是否会影响辨别视觉刺激时间顺序的能力，以及性别在时间处理中是否起作用。由于情绪的半球侧化，可能会预期左右视野之间存在半球不对称性。采用组块设计，在进行时间顺序判断任务之前，让受试者接触中性、消极和积极情绪图片。结果显示，男性受试者在消极和积极情绪状态下表现出类似的顺序阈值降低，而女性受试者在积极情绪状态下阈值升高，在消极情绪状态下阈值降低。此外，情绪对女性受试者的影响比对男性受试者的影响更大，并且未观察到半球侧化。这些观察结果表明情绪状态对视觉刺激的时间顺序处理有影响，并且表明存在性别差异，这可能与不同的情绪稳定性有关。
