Abstract

Facial expression recognition was investigated in 20 males with high functioning autism (HFA) or Asperger syndrome (AS), compared to typically developing individuals matched for chronological age (TD CA group) and verbal and non-verbal ability (TD V/NV group). This was the first study to employ a visual search, “face in the crowd” paradigm with a HFA/AS group, which explored responses to numerous facial expressions using real-face stimuli. Results showed slower response times for processing fear, anger and sad expressions in the HFA/AS group, relative to the TD CA group, but not the TD V/NV group. Reponses to happy, disgust and surprise expressions showed no group differences. Results are discussed with reference to the amygdala theory of autism.

Participants

Three groups of right-handed males (N = 60) were recruited from local mainstream schools, specialist ASD units and branches of the National Autistic Society. All participants were assessed for verbal ability using the British Picture Vocabulary Scale-second edition (BPVS II; Dunn, Dunn, Whetton & Burley, 1997), and for non-verbal ability using Ravens coloured progressive matrices (RCPM; Raven, Raven, & Court, 1998). The experimental group comprised 20 males, all of whom had been clinically

Analysis of response times (RT)

RTs of correct response only were analysed. One participant from the ASD group responded incorrectly to every trial with fear as a target. This empty cell was replaced with the mean RT for the remaining 19 HFA/AS participants for this expression. Results are shown in Fig. 4.

ANOVA was carried out with target emotion (6 levels; anger, disgust, fear, happiness, sadness, surprise) as the within-subjects factor, and group (3 levels; HFA/AS, TD CA and TD V/NV) as the between-subjects factor. This

Discussion

The present study investigated the abilities of children and adolescents with HFA/AS to search for a target face in a crowd based on six basic emotional expressions. Results showed a consistent pattern across HFA/AS and TD control groups such that identification of fear, anger and sadness target expressions was significantly slower than other emotions, with a corresponding reduction in accuracy for searches for fear and anger. In addition, identification of happy expressions showed the fastest

Acknowledgements

The authors would like to thank Chris Ashwin and Peter Hobson for useful discussion, and Vanger, Hoenlinger and Haken for permission to use their face stimuli in this study. Thanks also goes to the participants with HFA/AS and the typically developing participants who have kindly participated in this study.

      In these studies, no differences were found in mean RTs for a negative (i.e., angry) compared to a positive (i.e., happy) facial expression in the individuals with ASD, whereas the controls had faster mean RTs for negative compared to positive facial expressions (Isomura, Ito, Ogawa, & Masataka, 2014; Krysko & Rutherford, 2009; Sasson, Shasteen, & Pinkham, 2015). Another study demonstrated a happy face advantage effect (i.e., faster RTs for happy facial expressions compared to angry facial expressions) for both groups, but the individuals with ASD showed longer mean RTs for negative facial expressions (i.e., fear, anger and sadness) compared to only one of two control groups, which was not matched with regard to IQ (Farran, Branson, & King, 2011). These results may indicate less negative bias in the individuals with ASD.
