Videos of moving faces are more flattering than static images of the same face, a phenomenon dubbed the Frozen Face Effect. This may reflect an aesthetic preference for faces viewed in a more ecological context than still photographs. In the current set of experiments, we sought to determine whether this effect is unique to facial processing, or if motion confers an aesthetic benefit to other stimulus categories as well, such as bodies and objects-that is, a more generalized 'Frozen Effect' (FE). If motion were the critical factor in the FE, we would expect the video of a body or object in motion to be significantly more appealing than when seen in individual, static frames. To examine this, we asked participants to rate sets of videos of bodies and objects in motion along with the still frames constituting each video. Extending the original FFE, we found that participants rated videos as significantly more flattering than each video's corresponding still images, regardless of stimulus domain, suggesting that the FFE generalizes well beyond face perception. Interestingly, the magnitude of the FE increased with the predictability of stimulus movement. Our results suggest that observers prefer bodies and objects in motion over the same information presented in static form, and the more predictable the motion, the stronger the preference. Motion imbues objects and bodies with greater aesthetic appeal, which has implications for how one might choose to portray oneself in various social media platforms.
动态人脸视频比同一人脸的静态图像更具吸引力，这种现象被称为“冻结脸效应”。这可能反映了一种美学偏好，即更喜欢在更具生态意义的环境中观看人脸，而不是静态照片。在当前的一系列实验中，我们试图确定这种效应是否仅存在于面部处理中，或者运动是否也为其他刺激类别（例如身体和物体）带来了美学上的好处，即更普遍的“冻结效应”（FE）。如果运动是 FE 的关键因素，我们预计运动中的身体或物体的视频将比单个静态帧更具吸引力。为了检验这一点，我们要求参与者对运动中的身体和物体的视频集以及构成每个视频的静态帧进行评分。在扩展原始 FFE 的基础上，我们发现无论刺激域如何，参与者都认为视频比每个视频的相应静态图像更具吸引力，这表明 FE 很好地扩展到了面部感知之外。有趣的是，FE 的幅度随着刺激运动的可预测性而增加。我们的结果表明，观察者更喜欢运动中的身体和物体，而不是以静态形式呈现的相同信息，而且运动的可预测性越强，偏好就越强。运动赋予物体和身体更大的美感，这对人们如何在各种社交媒体平台上选择自我呈现方式具有重要意义。
