Abstract
While several studies suggest that individuals with autism use prior knowledge appropriately, others have found that this may be a particular area of weakness. The aim of the current study was to investigate whether individuals with autism and Asperger’s syndrome utilize prior knowledge when pairing objects with colours. Participants were presented with cards illustrating common objects and asked to pair them with one of two colour patches. Some target objects were coloured inappropriately (e.g. blue banana), allowing a participant to pair it either with blue or yellow. Results indicated that a majority of participants chose the associated in preference to the surface colour. This suggests that prior knowledge governed pairing in many individuals with autism and Asperger’s syndrome as it did in comparison groups, except in typically developing children aged 5 years. However, those with autism and moderate learning difficulties were less affected by prior knowledge than some of the other groups.
