具有威胁性和积极表情的面孔在视觉工作记忆（WM）中更容易被记住，并且在吸引注意力方面特别有效。我们问一个单一的威胁或快乐的脸的存在如何影响工作记忆的同时看到的面孔与中性表情。如果威胁捕获注意力，注意力决定WM，那么中性面孔的WM性能成本应该是显而易见的。然而，如果威胁以特定于对象的非竞争性方式促进处理，那么就不应该产生这样的成本。参与者观看三张中性脸和一张愤怒或快乐的脸，持续2秒。1秒后进行人脸识别测试。虽然工作记忆是更好的单身比nonsingletons和更好的愤怒与快乐的单身，工作记忆的中性面孔仍然不受任何单身。这些结果，结合眼动和反应时间的分析，反对选择性注意帐户的威胁为基础的好处WM和支持对象特定的增强通过威胁处理。
Faces with threatening versus positive expressions are better remembered in visual working memory (WM) and are especially effective at capturing attention. We asked how the presence of a single threatening or happy face affects WM for concurrently viewed faces with neutral expressions. If threat captures attention and attention determines WM, then a WM performance cost for neutral faces should be evident. However, if threat boosts processing in an object-specific, noncompetitive manner, then no such costs should be produced. Participants viewed three neutral and one angry or happy face for 2 s. Face recognition was tested 1 s later. Although WM was better for singletons than nonsingletons and better for angry versus happy singletons, WM for neutral faces remained unaffected by either singleton. These results, combined with eye movement and response time analyses, argue against a selective attention account of threat-based benefits to WM and support object-specific enhancement via threat processing.
