Resumo(s)
Cross-cultural studies of emotion recognition in nonverbal vocalizations not only support the universality hypothesis for
its innate features, but also an in-group advantage for culture-dependent features. Nevertheless, in such studies, diferences
in socio-economic-educational status have not always been accounted for, with idiomatic translation of emotional concepts being a limitation, and the underlying psychophysiological mechanisms still un-researched. We set out to investigate
whether native residents from Guinea-Bissau (West African culture) and Portugal (Western European culture)—matched
for socio-economic-educational status, sex and language—varied in behavioural and autonomic system response during
emotion recognition of nonverbal vocalizations from Portuguese individuals. Overall, Guinea–Bissauans (as out-group)
responded signifcantly less accurately (corrected p<.05), slower, and showed a trend for higher concomitant skin conductance, compared to Portuguese (as in-group)—fndings which may indicate a higher cognitive efort stemming from
higher difculty in discerning emotions from another culture. Specifcally, accuracy diferences were particularly found for
pleasure, amusement, and anger, rather than for sadness, relief or fear. Nevertheless, both cultures recognized all emotions
above-chance level. The perceived authenticity, measured for the frst time in nonverbal cross-cultural research, in the same
vocalizations, retrieved no diference between cultures in accuracy, but still a slower response from the out-group. Lastly, we
provide—to our knowledge—a frst account of how skin conductance response varies between nonverbally vocalized emotions, with signifcant diferences (p<.05). In sum, we provide behavioural and psychophysiological data, demographically
and language-matched, that supports cultural and emotion efects on vocal emotion recognition and perceived authenticity,
as well as the universality hypothesis.
