微笑肌肉刺激改变情绪面部对比中的神经处理。

Within embodied and predictive-processing frameworks, emotional face perception is informed by bodily states, such as proprioceptive facial feedback. In line with this, our earlier work showed that activation of smiling muscles with facial neuromuscular electrical stimulation (fNMES) can induce a happiness bias in emotional face perception, and reduce visual face processing demands. Here, we extended this research to examine whether the same facial muscle stimulation biases the emotional representation of a face when it serves as a perceptual template (prime) for comparison with a following ta
