While emotional expression via the body is universal across cultures, labelling emotions into ‘emotion-word’ categories is not universal, but learned – especially within the Western realm. The Theory of Constructed Emotions (TCE), proposes that emotion perception is a dynamic process; dependent on education and enculturation. Based on previous work using Western expressive gestures, we designed a video-stimuli library with gestures from a non-WEIRD cultural tradition [Henrich, et al., (2010). The weirdest people in the world? Behaviour and Brain Sciences, 33(2-3)], which our participants had different levels of enculturation with. Stimuli consisted of 6-second-long sequences of Iranian social dance gestures, danced 5x each with different emotional expressivities. Thus, the same movement trajectories were used to express five ‘basic’ emotions (anger, fear, joy, sadness, neutrality). Across five, one pre-registered, experiments with 400+ culturally Iranian, English and Southeast Asian participants, we tested how enculturation modulated emotion perception from full-body movement. We specifically did not merely ask our participants to indicate their self-ascribed ‘cultural group’, but applied enculturation screening questionnaires which returned continuous measures of enculturation with Iranian and English culture. Data was collected in 2020 (experiments 1-4), and in 2023 (experiment 5). Mixed-model logistic regressions showed that, categorical emotion labelling was modulated by English enculturation. Enculturation with Iranian culture produced a ‘joy bias’; a tendency to attribute joyful expressivity to the movements, in accordance with the joyful festive context in which these expressive social dance gestures usually occur. These results evidence an effect of enculturation on emotion perception, in line with the TCE.
