Human faces convey abundant social information. The influence of social information on duration estimation was examined by comparing a cartoon face (CF; social) condition with geometric plane figures, or CFs with internal elements disturbed from their normal position (non-social) condition, and also by comparing a human portrait facing the front (more social interaction) condition with the portrait facing the back (less social interaction) condition. Results showed that in the supra-second range, both CFs and human portraits facing the front led to an underestimation compared with non-social or less social information conditions. In the sub-second range, only portraits facing the front were overestimated compared with those facing the back and with the CFs. These results suggest that in the millisecond range, the biological information conveyed by faces may lead to higher arousal, which may result in accelerated clock speed and overestimation. In the supra-second range, it is possible that attention was diverted by social information, resulting in duration underestimation. Taken together, our results suggest that the different mechanisms were involved in duration perception of social information conveyed by face feature in the sub- and supra-second range.

亚秒和超秒范围内不同机制的社会信息对持续时间感知的影响：来自面部特征的证据

人脸传达着丰富的社会信息。通过将卡通脸（CF；社会）条件与几何平面图形或内部元素从其正常位置（非社会）条件受到干扰的 CF 进行比较，以及通过比较人像，来检查社会信息对持续时间估计的影响面向正面（更多社交互动）条件，肖像面向背面（较少社交互动）条件。结果表明，在超秒范围内，与非社交或较少社交信息的条件相比，CFs 和正面人像都导致低估。在亚秒范围内，只有面向正面的肖像与面向背面和 CF 的肖像相比被高估了。这些结果表明，在毫秒范围内，面部传达的生物信息可能会导致更高的唤醒，这可能会导致时钟速度加快和高估。在超秒范围内，注意力可能被社交信息转移，导致时长低估。总之，我们的结果表明，不同的机制涉及对亚秒和超秒范围内面部特征传达的社会信息的持续时间感知。
