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.

Categorical Speech Perception in Adults with Autism Spectrum Conditions / M. 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 et/ou numérique Auteurs : M. E. STEWART, Auteur ; A. M. PETROU, Auteur ; M. 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.

Social identities and mental well-being in autistic adults / C. A. MAITLAND in Autism, 25-6 (August 2021)  

Public ISBD [article]  inAutism > 25-6 (August 2021) . - p.1771-1783 Titre : Social identities and mental well-being in autistic adults Type de document : Texte imprimé et/ou numérique Auteurs : C.

STEWART, Auteur Article en page(s) : p.1771-1783 Langues : Anglais (eng) Mots-clés : Adult  Anxiety  Autism Spectrum Disorder  Autistic Disorder  Humans  Mental Health  Social Identification  adults  autism spectrum disorders  depression  mental health  social cognition and social behaviour  social identity  well-being  of interest with respect to the research, authorship and/or publication of this  article. Index. décimale : PER Périodiques Résumé : Social identities are groups that we are part of and influence how we think about ourselves. However, up until now there has been little examination of the groups that autistic people may belong to, and how these groups may influence their mental health. This survey-based study investigated whether autistic adults answer questions about social groups in a similar way to non-autistic non-autistic adults, including the types and number of social groups they may belong to, and whether these are associated with depression, anxiety and positive traits of mental well-being. In total, 184 autistic adults completed an online survey with questionnaires about their demographics, social groups and mental health. The results found that autistic adults reported on their social groups similarly to non-autistic people. There was a variety in the types and numbers of groups that autistic adults identified with. Some participants reported having no groups that they identified with, whereas others reported up to four groups. These included other autistic people, their family, friends, work colleagues and activity clubs among others. Autistic adults who felt connected with more groups reported better mental well-being. Feelings of connection to other autistic people and the family were also associated with better mental well-being. These results show that it is important for autistic people to be given opportunity to be part of groups that are meaningful to them, as this may be beneficial for their mental health.
