Abstract
Unusual responses to sensory stimuli have been described in autism spectrum disorder ASDThe study examined the frequencies of ‘unusual sensory interests’ and ‘negative sensory responses’ and their relation to functioning in a large ASD population n = 679 Having ‘unusual sensory interests’ was reported in 704 and ‘negative sensory responses’ in 660 of the ASD group Having ‘unusual sensory interests’ was associated with more severe reported and observed autism symptoms lower cognitive ability and lower adaptive skills In contrast having ‘negative sensory responses’ was only associated with more severe reported stereotyped behaviors It is suggested that having ‘unusual sensory interests’ is a part of a primary more severe type of ASD involving numerous developmental domains that might have a unique neurobiological origin
