ABSTRACT: The experience of aesthetic chills, often defined as a subjective response accompanied by goosebumps, shivers and tingling sensations, is a phenomenon often utilized to indicate moments of peak pleasure and emotional arousal in psychological research. However, little is currently understood about how to conceptualize the experience, particularly in terms of whether chills are general markers of intense pleasure and emotion, or instead a collection of distinct phenomenological experiences. To address this, a web-study was designed using images, videos, music videos, texts and music excerpts (from both an online forum dedicated to chills-eliciting stimuli and previous musical chills study), to explore variations across chills experience in terms of bodily and emotional responses reported. Results suggest that across participants (N = 179), three distinct chills categories could be identified: warm chills (chills co-occurring with smiling, warmth, feeling relaxed, stimulated and happy), cold chills (chills co-occurring with frowning, cold, sadness and anger), and moving chills (chills co-occurring with tears, feeling a lump in the throat, emotional intensity, and feelings of affection, tenderness and being moved). Warm chills were linked to stimuli expressing social communion and love; cold chills were elicited by stimuli portraying entities in distress, and support from one to another; moving chills were elicited by most stimuli, but their incidence were also predicted by ratings of trait empathy. Findings are discussed in terms of being moved, the importance of differing induction mechanisms such as shared experience and empathic concern, and the implications of distinct chills categories for both individual differences and inconsistencies in the existing aesthetic chills literature.
