Deficits in facial emotion recognition and implicit attitudes toward emotion among adolescents with high functioning autism spectrum disorder.

OBJECTIVE

Impaired social interaction is one of the core characteristics of autism spectrum disorder (ASD). This study was conducted to compare the facial emotion recognition (FER) abilities and emotional interference of adolescents with and without high-functioning ASD by performing the FER Task (FERT) using the faces of Taiwanese people and the Implicit Association Test (IAT), respectively.

METHODS

This study recruited 71 adolescents with high-functioning ASD who aged at 11 to 18 years old as the ASD group and 63 adolescents without ASD from the Taiwanese community as the non-ASD group. We investigated FER abilities by conducting the FERT on six types of emotional expression with a three-level intensity rating, and we performed the IAT for evaluating the strength of a person's automatic association with mental representations of emotions in memory.

RESULTS

Compared with the non-ASD group, the ASD group performed significantly worse on facial emotion differentiation and the ranking and rating of emotional intensity in the FERT. The ASD group had higher IAT scores than the non-ASD group.

CONCLUSION

The results suggest that adolescents with high-functioning ASD have subtle deficits in facial emotion processing and emotional interference.
