Asymmetries of influence: differential effects of body postures on perceptions of emotional facial expressions.

Fearful postures impaired accurate perception of sad faces more than angry postures, they caused the largest increase in response times for both sad and angry faces (although the effect for angry faces was only marginally significant), and they were the only posture to alter the pattern of errors, causing participants to label the associated face as ‘fear’, rather than ‘sad’ or ‘angry’.
