Sympathy Crying: Insights from Infrared Thermal Imaging on a Female Sample

Area of Science:

• Psychophysiology
• Neuroscience
• Emotional response research

Background:

• Sympathy crying is a complex emotional and physiological phenomenon.
• Current theories struggle to link crying to specific autonomic nervous system (ANS) subdivisions.
• The precise emotional origins of sympathy crying remain debated.

Purpose of the Study:

• To investigate the psychophysiological underpinnings of sympathy crying.
• To explore the role of the autonomic nervous system (ANS) in emotional crying.
• To utilize functional thermal infrared imaging (FTII) as a novel method for studying ANS activity during crying.

Main Methods:

• Functional thermal infrared imaging (FTII) was employed to contactless measure ANS activity.
• Female participants were exposed to emotionally evocative films to induce crying.
• Facial temperature patterns were recorded before, during, and after crying episodes.

Main Results:

• Significant temperature increases were observed in the forehead, peri-orbital region, cheeks, and chin prior to and during crying.
• A contrasting temperature decrease was noted in the maxillary area, attributed to emotional sweating.
• These findings suggest a complex interplay between the sympathetic and parasympathetic nervous systems during sympathy crying.

Conclusions:

• Sympathy crying results from a dynamic interaction between the sympathetic and parasympathetic nervous systems, with parasympathetic activity potentially initiating the response.
• The emotional roots of sympathy crying appear linked to internal subjective factors, personal experiences, and individual attributes.
• Tears of sympathy may serve as a form of emotional catharsis or a manifestation of shared sadness.
