“…7 It may be that the forms of emotional music and movement are fixed by iconic, functional relationships that are shared across cultures. 61,68 This may be why lullabies are slow and consonant across a global sample of ethnographic reports and recordings 3 and why high emotional arousal is expressed using harsh-sounding, high spectral centroid sounds, even across species of terrestrial vertebrates. 69 Music, movement, and crossmodal neural representations may be well suited to communicate iconic concepts that vary in magnitude, whereas language may be well suited to communicate symbolic concepts that vary in kind.…”

Emotion communication must be robust to interference from a noisy environment. One safeguard against interference is crossmodal redundancy-for example, conveying the same information using both sound and movement. Emotion perceivers should therefore be adapted to e iciently detect crossmodal correspondences, increasing the likelihood that emotion signals will be understood. One possible such adaptation is the use of a single neural code for both auditory and visual information. To investigate this, we tested two hypotheses: ( ) that distinct auditory and visual brain areas represent emotion expressions using the same parameters, and ( ) that auditory and visual expressions of emotion are represented together in one brain area using a supramodal neural code. We presented emotion expressions during functional magnetic resonance imaging (N= , scan hrs/participant) and tested these hypotheses using representational similarity analysis (Kriegeskorte & Kievit, ). A single model of stimulus features and emotion content fit brain activity in both auditory and visual areas, supporting hypothesis ( ), and posterior superior temporal gyrus represented both auditory and visual emotion expressions, supporting hypothesis ( ). These results hold for both discrete and mixed (e.g., Happy-Sad) emotional expressions. Surprisingly, further exploratory analysis showed auditory and visual areas represent stimulus features and emotion content even when stimuli are presented in each area's non-preferred modality.
