我们测试了社交焦虑的人是否在处理低空间频率（LSF）的面部信息时表现更好。为此，我们提出了社会焦虑和nonanxious参与者与混合面部刺激，包含独立的面部表情在高（HSF）和LSF波段。在两项任务中，参与者要么根据“愤怒”对图像进行评级，要么必须学习混合面部表情如何预测即将到来的目标的位置。我们发现，大多数加性效应的LSF和HSF的信息在两组的评级任务。相比之下，社交焦虑的参与者表现出更好的预测性能的LSF表达的内隐学习任务。我们的结论是，社交焦虑的参与者更敏感的面部信息内LSF，但这种更高的敏感性可能会变得最明显的间接任务。
We tested whether socially anxious individuals perform better in processing facial information with low spatial frequencies (LSFs). For this, we presented socially anxious and nonanxious participants with hybrid face stimuli that contained independent facial expressions in high (HSF) and LSF bands. In two tasks, participants either rated the images according to "angriness" or had to learn how hybrid facial expressions predicted the location of an upcoming target. We found mostly additive effects of LSF and HSF information in the rating task for both groups. In contrast, socially anxious participants showed better prediction performance for LSF expressions in the implicit learning task. We conclude that socially anxious participants are more sensitive to facial information within LSFs, but this higher sensitivity may become mostly evident in indirect tasks.
