Emotion perception from vocal cues: Testing the influence of emotion intensity and sex on in-group advantage

The present study examined individuals’ ability to identify emotions being expressed in vocal cues depending on the accent of the speaker as well as the intensity of the emotion being expressed. Australian and Canadian participants listened to Australian and Canadian speakers express pairs of emotions that fall within the same emotion family but vary in intensity (e.g., anger vs. irritation). Accent of listener was unrelated to emotion recognition. Instead, performance varied more based on emotion intensity and sex; Australian and Canadian participants generally found high intensity emotions easier to recognize compared to low intensity emotions as well as emotion conveyed by females compared to males. Participants found it particularly difficult to recognize the expressed emotion of Australian males. The results suggest the importance of considering the context in which emotion recognition is embedded.
