Furthermore, the ability to recognize fearful but not disgusted expressions was negatively correlated with the severity of social dysfunction in PDD-NOS and ASP.
Contemptuous faces did not elicit stronger amygdala activation than did disgusted expressions.
Observers from both cultures were randomly allocated to one of these conditions and learned two series of 14 of Western Caucasian and East Asian faces with neutral, happy or disgusted expressions presented for 10 seconds each.
Although both angry and disgusted facial expressions induce negative emotional states in perceivers, angry expressions induce higher arousal than do disgusted expressions [ 22].
In summary, factors other than group and stimulus type had no significant effect on the recognition of disgusted expressions.
The t-test showed that delinquents selected anger as the label to describe disgusted expressions more frequently than did control participants.
Extending these previous findings, the present study provides the first clear evidence that delinquents have a bias toward the misrecognition of others' disgusted expressions as anger.
These results suggest that one of the underpinnings of delinquency might be impaired recognition of emotional facial expressions, with a specific bias toward interpreting disgusted expressions as hostile angry expressions.
