Abstract

This study investigated emotion recognition abilities and visual scanning of emotional faces in 16 Fragile X syndrome (FXS) individuals compared to 16 chronological-age and 16 mental-age matched controls. The relationships between emotion recognition, visual scan-paths and symptoms of social anxiety, schizotypy and autism were also explored. Results indicated that, compared to both control groups, the FXS group displayed specific emotion recognition deficits for angry and neutral (but not happy or fearful) facial expressions. Despite these evident emotion recognition deficits, the visual scanning of emotional faces was found to be at developmentally appropriate levels in the FXS group. Significant relationships were also observed between visual scan-paths, emotion recognition performance and symptomology in the FXS group.

1
‘Normal’ was included rather than ‘neutral’ on the written response list due to a large number of young controls reading neutral as normal during piloting. Verbal task instructions, however, were given to all participants prior to beginning the emotion recognition task explaining the four choices as: happy, scared, angry, and neutrala normal or blank face with no expression.
 
2
65 % of all participants (FXS: 68.8 %; CA-matched controls: 56.3 %; MA-matched controls: 73.3 %, p = 0.536) failed to correctly label this image as neutral; over 90 % of errors judged the face to be angry.
 
3
The analysis was conducted with males excluded and the pattern of results was similar. The only modification to results was that the difference between the FXS and CA-matched controls for sensitivity in recognizing neutral expressions now failed to reach significance (p = 0.101).
 
4
Descriptive analyses revealed one outlier in each of the CA and MA matched groups. Analyses were performed with both the outliers removed and retained. The pattern of results was the same for both analyses; as such these data points were retained in the analysis.
