Autistic Traits and Enhanced Perceptual Representation of Pitch and Time / Mary E. STEWART in Journal of Autism and Developmental Disorders, 48-4 (April 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-4 (April 2018) . - p.1350-1358 Titre : Autistic Traits and Enhanced Perceptual Representation of Pitch and Time Type de document : texte imprimé Auteurs : Mary E.

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 Psychosocial Predictors of Depressive Symptoms / Kirsty JONES ; Emily O'DOWD ; Bonnie AUYEUNG ; Gnanathusharan RAJENDRAN ; Mary Elizabeth STEWART in Journal of Autism and Developmental Disorders, 55-7 (July 2025)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 55-7 (July 2025) . - p.2368-2376 Titre : Autistic Traits and Psychosocial Predictors of Depressive Symptoms Type de document : texte imprimé Auteurs : Kirsty JONES, Auteur ; Emily O'DOWD, Auteur ; Bonnie AUYEUNG, Auteur ; Gnanathusharan RAJENDRAN, Auteur ; Mary Elizabeth STEWART, Auteur Article en page(s) : p.2368-2376 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Higher rates of depression and of depressed mood are associated with autistic traits, and both are associated with social interaction factors, such as social self-efficacy, social motivation and loneliness. This study examined whether these social factors explain the association between autistic traits and depression. 658 participants (527 women) completed an online survey with measures of autistic traits (AQ), social self-efficacy (Social Self-Efficacy Scale), social motivation (Social Striving Assessment Scale), loneliness (UCLA Loneliness Scale) and depressive symptoms (Beck Depression Inventory-II). A mediation analysis found the relationship between autistic traits and depressive symptoms was fully mediated by the other three factors (?[indirect] = .005, z = 2.63, p < .01; ?[direct] = .05, z = 1.58, p > .05), forming a pathway from autistic traits, to social self-efficacy, to social motivation, to loneliness and finally to depressive symptoms. These results suggest that targeting social self-efficacy may break this pathway and disrupt this relationship. Interventions targeting supporting positive social interaction should be considered.

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.

Categorical Speech Perception in Adults with Autism Spectrum Conditions / Mary E. STEWART in Journal of Autism and Developmental Disorders, 48-1 (January 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-1 (January 2018) . - p.72-82 Titre : Categorical Speech Perception in Adults with Autism Spectrum Conditions Type de document : texte imprimé Auteurs : Mary E. STEWART, Auteur ; Alexandra M. PETROU, Auteur ; Mitsuhiko OTA, Auteur Article en page(s) : p.72-82 Langues : Anglais (eng) Mots-clés : Auditory discrimination  Autism  Categorical speech perception  Language  Phoneme Index. décimale : PER Périodiques Résumé : This study tested whether individuals with autism spectrum conditions (n = 23) show enhanced discrimination of acoustic differences that signal a linguistic contrast (i.e., /g/ versus /k/ as in 'goat' and 'coat') and whether they process such differences in a less categorical fashion as compared with 23 IQ-matched typically developed adults. Tasks administered were nonverbal IQ, verbal IQ, 5 language measures, a speech perception task, and the ADOS. The speech perception task measured the discrimination of paired exemplars along the /g/-/k/ continuum. Individuals with autism spectrum conditions did not show enhanced discrimination of speech perception. Categorical speech perception was correlated with verbal ability of reading, lexical decision, and verbal IQ in individuals with autism spectrum conditions.

Emotional recognition in autism spectrum conditions from voices and faces / Mary E. STEWART in Autism, 17-1 (January 2013)  

Public ISBD [article]  inAutism > 17-1 (January 2013) . - p.6-14 Titre : Emotional recognition in autism spectrum conditions from voices and faces Type de document : texte imprimé Auteurs : Mary E.

The new test of vocal emotion contained trials in which the vocal emotion of the sentence were congruent, incongruent, or neutral with respect to the semantic content. We also included a condition in which there was no semantic content (an ‘mmm’ was uttered using an emotional tone). Performance was compared between 11 adults with ASC and 14 typically developed adults. Identification of emotion from sentences in which the vocal emotion and the meaning of sentence were congruent was similar in people with ASC and a typically developed comparison group. However, the comparison group was more accurate at identifying the emotion in the voice from incongruent and neutral trials, and also from trials with no semantic content. The results of the vocal emotion task were correlated with performance on a face emotion recognition task. In decoding emotion from spoken utterances, individuals with ASC relied more on verbal semantics than did typically developed individuals, presumably as a strategy to compensate for their difficulties in using prosodic cues to recognize emotions.
