从点探测任务计算指数的新方法测量注意力偏差的时间动态或随着时间的推移，注意力偏向和远离情绪刺激的波动。然而，目前还不清楚如何任务特定的参数，如刺激效价和刺激起始时间（SOA）以及参与者的性别影响时间动态的注意偏差。为了解决这个问题，男性和女性参与者（N = 106）完成了一个恐惧或快乐的脸点探测任务，四个级别的SOA（84毫秒，168毫秒，336毫秒和672毫秒）。结果表明，注意偏向的时间动态是（1）最大的最长SOA，（2）更大的女性，（3）刺激效价不敏感。这些研究结果表明，参与者的性别和任务的时间，而不是刺激效价，与时间动态的注意力偏差，并应考虑在未来的研究利用这种方法。
New methods of calculating indices from the dot-probe task measure temporal dynamics in attention bias or fluctuations in attention bias towards and away from emotional stimuli over time. However, it is unclear how task-specific parameters such as stimulus valence and stimulus onset asynchrony (SOA) as well as participant sex affect temporal dynamics in attention bias. To address this, male and female participants (N = 106) completed either a fearful or happy face dot-probe task with four levels of SOA (84 ms, 168 ms, 336 ms, and 672 ms). Results suggest that temporal dynamics in attention bias are (1) greatest at the longest SOA, (2) greater in females, and (3) insensitive to stimulus valence. These findings indicate that participant sex and task timing, but not stimulus valence, are related to temporal dynamics in attention bias and should be considered in future studies utilizing this approach.
