Recognizing humanity: dehumanization predicts neural mirroring and empathic accuracy in face-to-face interactions

Area of Science:

• Social Psychology
• Cognitive Neuroscience
• Human Interaction Studies

Background:

• Dehumanization, the failure to recognize others' complexities, is linked to violence but also theorized in daily life.
• Understanding everyday dehumanization is crucial for social cognition and interpersonal dynamics.

Purpose of the Study:

• To measure the presence and effects of dehumanization in face-to-face interactions between strangers.
• To investigate how perceptions of others' humanity influence neural processing and behavior.

Main Methods:

• Studied face-to-face dyadic interactions between strangers.
• Measured neural mirroring using electroencephalography (EEG) mu-suppression.
• Assessed empathic accuracy and cooperative task performance.

Main Results:

• Significant variance observed in how participants perceived each other's humanity.
• Higher perceived humanity correlated with stronger neural mirroring (EEG mu-suppression).
• Participants showed marginally better empathic accuracy and cooperative task performance with partners perceived as more human.

Conclusions:

• Differences in recognizing others' humanity exist even in brief, face-to-face encounters.
• Perceptions of humanity impact neural simulation, empathy, and cooperation in everyday interactions.
• Findings highlight the significance of mundane variations in perceiving humanity for social functioning.
