表情识别的模拟模型认为，为了理解他人的面部表情，个体将感知到的表情映射到在感知到的情绪的体验期间活跃的相同感觉运动表征上。为了探讨这一观点，本研究探讨了面部表情和身份识别能力的一个罕见的一组参与者谁显示促进感觉运动模拟（镜像触摸联觉）。触觉联觉者在观察别人的触摸时，会感受到自己身体上的触摸。这些体验与共享触摸网络（在被动观察和触摸体验期间活跃的大脑区域）中的感觉运动模拟有关。触觉联觉者在面部表情识别方面的表现优于非联觉者，但在面部记忆或面部身份感知的控制措施方面则不然。这些发现意味着感觉运动模拟过程在面部情感识别中的作用，但不是面部身份。
Simulation models of expression recognition contend that to understand another's facial expressions, individuals map the perceived expression onto the same sensorimotor representations that are active during the experience of the perceived emotion. To investigate this view, the present study examines facial expression and identity recognition abilities in a rare group of participants who show facilitated sensorimotor simulation (mirror-touch synesthetes). Mirror-touch synesthetes experience touch on their own body when observing touch to another person. These experiences have been linked to heightened sensorimotor simulation in the shared-touch network (brain regions active during the passive observation and experience of touch). Mirror-touch synesthetes outperformed nonsynesthetic participants on measures of facial expression recognition, but not on control measures of face memory or facial identity perception. These findings imply a role for sensorimotor simulation processes in the recognition of facial affect, but not facial identity.
