It is unclear how music elicits chills (emotional experiences accompanied by goosebumps, shivers, and tingling sensations), and what psychological mechanisms underlie the response. Crucially, current explanations of chills struggle to encapsulate the variability of results linking the experience to musical features, psychophysiological activity, and individual differences, suggesting there may be distinct types of musical chills elicited through different underlying mechanisms. This study aimed to distinguish two types of musical chills: vigilance chills, linked to awe, expectancy, and auditory looming; and social chills, linked to being moved, empathy, and social bonding. Participants listened to four music excerpts containing moments of contrast (sudden dynamic changes). Two excerpts were paired with extramusical information provided before listening, with the other two accompanied by visual animations; the information and animations emphasized either vigilance (i.e., musical structure) or social (i.e., bittersweet moving narrative) aspects, forming vigilance and social conditions for each stimulus. Participants reported chills via button presses, rated experiences of awe and being moved, and had skin conductance and temperature data collected; individual differences in cognitive processing style (empathizing and systemizing) were also explored. Results show that vigilance conditions elicited higher ratings of awe, and social conditions elicited higher ratings of being moved. Chills during experiences of awe (vigilance chills) were accompanied by increased skin conductance and decreased skin temperature compared to chills during experiences of being moved (social chills). Cognitive processing styles were unrelated to listener experiences. Findings are discussed in terms of chills theories, reinterpreting previous research, and broader music and emotion frameworks.
