Effects of Aesthetic Chills on a Cardiac Signature of Emotionality.

Sumpf M, Jentschke S, Koelsch S - PLoS ONE (2015)

Bottom Line: Previous studies have shown that a cardiac signature of emotionality (referred to as EK, which can be computed from the standard 12 lead electrocardiogram, ECG), predicts inter-individual differences in the tendency to experience and express positive emotion.EK values, as well as heart rate, increased significantly during moments of peak positive emotion accompanied by piloerection.These results are the first to provide evidence for an influence of momentary psychological state on a cardiac signature of emotional personality (as reflected in EK values).

ABSTRACT

Background: Previous studies have shown that a cardiac signature of emotionality (referred to as EK, which can be computed from the standard 12 lead electrocardiogram, ECG), predicts inter-individual differences in the tendency to experience and express positive emotion. Here, we investigated whether EK values can be transiently modulated during stimulation with participant-selected music pieces and film scenes that elicit strongly positive emotion.

Methodology/principal findings: The phenomenon of aesthetic chills, as indicated by measurable piloerection on the forearm, was used to accurately locate moments of peak emotional responses during stimulation. From 58 healthy participants, continuous EK values, heart rate, and respiratory frequency were recorded during stimulation with film scenes and music pieces, and were related to the aesthetic chills. EK values, as well as heart rate, increased significantly during moments of peak positive emotion accompanied by piloerection.

Conclusions/significance: These results are the first to provide evidence for an influence of momentary psychological state on a cardiac signature of emotional personality (as reflected in EK values). The possibility to modulate ECG amplitude signatures via stimulation with emotionally significant music pieces and film scenes opens up new perspectives for the use of emotional peak experiences in the therapy of disorders characterized by flattened emotionality, such as depression or schizoid personality disorder.

Average physiological changes in participants who had piloerection (black bars) and their matched partners (white bars).Black bars depict the difference in physiological activity between the entire piloerection passage and a random control passage of similar length within the same stimulus and subject. White bars depict the same difference scores, but for matched partner subjects who did not have piloerection in either of the passages. All scores are normalized with respect to activity during the baseline period. Ek = emotional index Eκ, HR = heart rate, RF = respiratory frequency. HR and Eκ scores are different from zero in the piloerection condition (black bar), RF scores are different from zero in the no-piloerection condition (white bar). The differences in HR scores and in Eκ scores (black versus white bars) are significant on a 0.05 significance level.

Mentions: In Fig 3, black bars show the “difference score” (see Methods) of participants who had piloerection, i.e., their difference in physiological activity between the entire piloerection passage and a random control passage within the same stimulus. White bars show the “difference score” of matched partners.
