Dynamic and static angry faces influence time perception differently—Evidence from ERPs
Frontiers in Neuroscience, 2023 The dynamic characteristics of facial expressions might affect time perception. Compared with static emotional faces, dynamic emotional faces are more intense, have higher ecological validity, and contain time series information, which may lead to time ...
