Autism Spectrum Disorders (ASD) ar characterised by social and communication impairment, yet evidence for de?cits in the ability to recognise facial expressions of basic emotions is con?icting. some(prenominal) studies reporting no de?cits have used stimuli that may be too simple (with associated ceiling effects), for example, 100% full-blown expressions.



In order to investigate subtle de?cits in facial emotion recognition, 21 adolescent males with high-functioning Austism Spectrum Disorders (ASD) and 16 age and IQ matched typically developing control males completed a new nice test of facial emotion recognition which uses dynamic stimuli of varying intensities of expressions of the six basic emotions (Emotion Recognition Test; Montagne et al., 2007). Participants with ASD were found to be less accurate at processing the basic frantic expressions of disgust, anger and admiration; disgust recognition was most stricken at 100% intensity and lower levels, whereas recognition of surprise and anger were intact at 100% but impair at lower levels of intensity. © 2010 Elsevier Ltd.
