Aesthetic Chills Cause an Emotional Drift in Valence and Arousal

The Emotion That Doesn’t Fit the Map

Jain and colleagues’ 2023 paper reports a finding that is empirically precise and philosophically radical: aesthetic chills do not simply intensify whatever the perceiver was already feeling but move the perceiver into a qualitatively different affective state. Using continuous self-report measures of valence (pleasant to unpleasant) and arousal (calm to activated), the researchers tracked participants’ emotional trajectories before, during, and after chill events elicited by music and film. The data reveal a consistent pattern: chills shift valence toward greater positivity and produce a paradoxical arousal signature — simultaneously increasing alertness and deepening calm. The resulting state, which the authors characterize as “alert tranquility,” occupies a region of affective space that dimensional models of emotion do not adequately predict or describe.

A Crack in the Circumplex

Russell’s circumplex model of affect — the dominant framework in emotion research for four decades — arranges emotional states along two independent dimensions: valence (positive to negative) and arousal (activated to deactivated). High valence and high arousal yields excitement; high valence and low arousal yields contentment; low valence and high arousal yields anxiety. The model assumes that these two dimensions fully characterize the affective landscape. Jain’s finding that aesthetic chills produce a state that is simultaneously high-arousal and low-arousal — alert yet tranquil — suggests that the circumplex has a structural limitation. There exist emotional states that the two-dimensional map cannot locate because they involve the coincidence of opposites rather than the linear combination of orthogonal dimensions.

The Coincidentia Oppositorum in the Body

For depth psychology, the coincidence of opposites is not a paradox to be resolved but a signature of the numinous. Jung’s concept of the transcendent function describes precisely this: a psychic state in which opposing tendencies — conscious and unconscious, thinking and feeling, tension and surrender — are held in dynamic equilibrium rather than collapsing into one pole or the other. The “alert tranquility” Jain identifies as the affective signature of aesthetic chills is the body’s version of the transcendent function — a somatic state in which the organism is simultaneously activated and at rest, engaged and surrendered, moved and still. That this state is produced by beauty rather than by meditation, therapy, or pharmaceutical intervention suggests that aesthetic experience provides a natural route to the coincidentia oppositorum that the depth tradition has always identified as the hallmark of psychological integration.

From Drift to Transformation

The paper’s use of “drift” is apt and revealing. The emotional shift produced by aesthetic chills is not instantaneous but gradual — it unfolds over seconds, altering the perceiver’s affective landscape as a current alters the course of a vessel. This temporal quality distinguishes aesthetic chills from startle responses, fight-or-flight reactions, and other sudden emotional events. The body does not lurch into alert tranquility; it drifts there, carried by the beauty of the stimulus. The clinical implication is that aesthetic experience may function as a gentle modulator of affective states — a way of shifting the autonomic nervous system’s set-point without the intensity of exposure therapy or the invasiveness of pharmacology. For patients stuck in chronic states of hyperarousal or hypoarousal, the aesthetic chill offers a natural pathway toward the middle ground that polyvagal theory identifies as the window of tolerance and that depth psychology recognizes as the ego’s proper relation to the Self.
