灵长类动物已经进化到能够迅速发现环境中的危险并做出反应。然而，参与威胁刺激的机制尚未完全了解。点探测任务是研究人类这些机制最广泛使用的实验范式之一。然而，迄今为止，在非人类灵长类动物中进行的研究很少。这项研究的目的是调查点探测任务是否可以测量黑猩猩对威胁性面孔的注意偏向。八只成年黑猩猩参与了一系列触屏点探测任务。我们预测黑猩猩对威胁性面孔的反应速度要快于对中性面孔的反应速度，对高威胁强度面孔（尖叫）的反应速度要快于低威胁强度面孔（露出牙齿）的反应速度。与预测相反，黑猩猩对威胁性面孔的反应时间与对中性面孔的反应时间没有差异。此外，我们发现面对高威胁强度和低威胁强度的反应时间没有差异。总之，我们没有发现任何证据表明触摸屏点探测任务可以测量黑猩猩对威胁性面孔的注意偏差。讨论了使用任务测量人类和非人类灵长类动物情绪注意的方法局限性，包括刺激威胁强度、情绪状态、刺激呈现时间和手动反应。
Primates have evolved to rapidly detect and respond to danger in their environment. However, the mechanisms involved in attending to threatening stimuli are not fully understood. The dot-probe task is one of the most widely used experimental paradigms to investigate these mechanisms in humans. However, to date, few studies have been conducted in non-human primates. The aim of this study was to investigate whether the dot-probe task can measure attentional biases towards threatening faces in chimpanzees. Eight adult chimpanzees participated in a series of touch screen dot-probe tasks. We predicted faster response times towards chimpanzee threatening faces relative to neutral faces and faster response times towards faces of high threat intensity (scream) than low threat intensity (bared teeth). Contrary to prediction, response times for chimpanzee threatening faces relative to neutral faces did not differ. In addition, we found no difference in response times for faces of high and low threat intensity. In conclusion, we found no evidence that the touch screen dot-probe task can measure attentional biases specifically towards threatening faces in our chimpanzees. Methodological limitations of using the task to measure emotional attention in human and non-human primates, including stimulus threat intensity, emotional state, stimulus presentation duration and manual responding are discussed.
