Dr Catherine Jones has just published an article in the Journal of Autism and Developmental Disorders with her collaborators at City University, London.
When faces are emotional people judge having seen them for longer compared to faces that do not show emotion – this is a demonstration of implicit sensitivity to emotion. Catherine and her collaborators were interested in whether autistic people show this sensitivity. Across two studies, they found that there were no differences in sensitivity between autistic and non-autistic adults and performance on the task was not related to the amount of autistic traits a person reported. The data are interesting as they suggest that at a very basic level autistic people do respond to emotionally arousing images in a similar way to non-autistic people.
