We test whether there is a correlational pattern of enhancement across the broader autism phenotype and whether this correlation occurs for the discrimination of pitch, time and loudness. Scores on the Autism-Spectrum Quotient correlated significantly with the pitch discrimination (r = -0.51, p < 0.05) and the time-interval discrimination (r = -0.45, p < 0.05) task that were based on a fixed reference. No correlation was found for intensity discrimination based on a fixed reference, nor for a variable reference based time-interval discrimination. The correlations suggest a relationship between autistic traits and the ability to form an enhanced, stable and highly accurate representation of auditory events in the pitch and time dimensions.

Autistic Traits and Sensitivity to Interference With Flavour Identification / Andrea Irene CLARK in Autism Research, 6-5 (October 2013)  

Public ISBD [article]  inAutism Research > 6-5 (October 2013) . - p.332-336 Titre : Autistic Traits and Sensitivity to Interference With Flavour Identification Type de document : texte imprimé Auteurs : Andrea Irene CLARK, Auteur ; Paul Shane HUGHES, Auteur ; Manon GRUBE, Auteur ; Mary Elizabeth STEWART, Auteur Article en page(s) : p.332-336 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  autistic traits  personality  multisensory perception  flavour perception Index. décimale : PER Périodiques Résumé : We assessed whether autistic traits are related to the ability to identify flavour. In general, the colour of the food or drink facilitates identification of its flavour. In the current study, the colour of drinks either provided congruent, incongruent or ambiguous (colourless) information about the flavour. Participants identified the flavours of 12 drinks from a list and completed a measure of autistic traits, the Autism-Spectrum Quotient (AQ). In line with previous studies, flavour identification was impaired in incongruent conditions, while identification in congruent conditions was not improved when compared with that in ambiguous conditions. AQ scores were related to flavour identification in incongruent conditions, in that as the AQ score increased, accuracy of flavour identification decreased. There were no relationships found in the congruent or ambiguous conditions. This finding is in line with the idea that conflicting sensory information may be more disruptive for individuals on the autism spectrum.
