Press Release: Physical Topography of Feelings Revealed in Study

Posted on December 01, 2023 by Admin

Researchers conducted multiple experiments comprising guided stimuli and a novel topographical self-reported computer-based method named "embody" to investigate the associations between emotions and bodily topographies. They linked these emotions to cohorts from different geographies and racial backgrounds and revealed that subjective emotional feelings are associated with identifiable maps of bodily sensations. These findings support hypotheses and models wherein somatosensation and embodiment are critical aspects of emotional processing. This research forms the foundation for identifying and further delving into hitherto hard-to-understand mood disorders such as depression and anxiety, which are assumed to alter standard emotional processing.

Mind Over Body

Have you ever experienced emotions that make you feel things in your body? You aren't alone. Humans often experience altered bodily feelings in response to their temporal emotional landscape, such as pounding hearts and light walking when on the way to meet a lover for a date in a park, as opposed to tight muscles, sweaty hands, and a choked-up throat when anxious. Neural research and studies on somatic responses to stress suggest that an individual's emotional state acts as a trigger for modifying the cardiovascular, neuroendocrine, skeletomuscular, and autonomic nervous systems (ANS) in preparation for assumed events.

More recent research has investigated the verbal descriptions of emotions and bodily states – "cold feet" is a common phrase to describe a sudden bout of anxiety and reluctance prior to a previous eagerly anticipated wedding, as is "heartbroken" is a potentially even more common description of the feelings accompanying disappointments in love. These findings suggest constant feedback between individuals' somatic, emotional, and descriptive functions, though adequate research in the field remains lacking.

Interestingly, clinical research has recently identified that our thoughts about our feelings have minute yet significant voluntary control over a previously assumed completely involuntary phenomenon – perceptions of emotion-related somatic states have been found to alter skeletomuscular, ANS, and neuroendocrine responses, suggesting that an individual's conscious perception of their environment can better fine-tune their voluntary and potentially involuntary behaviors to suit the challenges of their surroundings better.

Understanding the links between mind and body and revealing if the mind can actually control the body to a certain extent can help researchers both identify and treat mood disorders such as anxiety and depression and is hence essential in today's increasingly stressful world.

Study

In the present study, researchers developed a unique computer-aided, topographical self-reporting method christened "embody." The program was designed to allow participants to visually represent and reproduce the altered bodily states they felt in response to specific, researcher-provided stimuli. Two digital silhouettes of bodies were provided to each participant who was asked to color physical regions that they felt experienced altered (increased or decreased) activity on exposure to specific, emotionally triggering words, movies, stories, or facial expressions.

The study cohort comprised 773 total volunteers separated into five cohorts corresponding to the five experimental treatments conducted herein. Most participants were Finnish-speaking except for cohorts 1b (Swedish) and 1c (Taiwanese Hokkien). Experiment 1 a-c comprised the presentation of emotionally triggering words; Experiment 2 used guided emotional imagery; Experiment 3 used emotional movies; Experiment 4 presented pictures of basic facial expressions; and Experiment 5 used emBODY bodily sensations (BSMs) averaged from Experiment 1 participants.

Statistical analyses of participant inputs were carried out using random effects analyses and mass univariate t-tests, corrected for false positives using false discovery rate (FDR) corrections with alpha levels of 0.05. Hierarchical clustering and Spearman correlations were used to assess group- and individual BSM associations, respectively.

Results and Conclusion

The present study revealed that distant distinct BSMs were associated with basic and complex emotional responses to presented stimuli. Patterns revealed by the emBODY methodology were found to be consistent across six basic emotions categorically represented in the body. Encouragingly, these categories match previously reported results from brain imagining and behavioral investigations, highlighting that the emotional systems and corresponding neural mechanisms are instrumental in emotional processing.

A noteworthy finding is that basic emotions trigger elevated sensational responses in the upper chest area, corresponding to breathing and heart rate alterations. Approach-associated stimuli such as anger and happiness resulted in sensations in the upper limbs. Sadness, in contrast, reduced limb activity and induced a reluctance to move. Disgust prompted sensational responses in the digestive system and throat region. The head region showed alterations (increased or decreased activity) in response to all stimuli, and happiness was found to universally increase sensations across all bodily components.

While the above argument can be made, consistency between Finnish, Taiwanese, and Swedish language natives in BSM reading discredits it. Finally, complex emotions were found to be more nuanced and challenging to categorize than simple emotions. However, statistical analyses still identify complex emotional responses as discrete events.
