Determining differences in social cognition between high-functioning autistic disorder and other pervasive developmental disorders using new advanced “mind-reading” tasks / Miho KURODA in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)

However, it is unclear whether this deficit in social cognition differs between the subgroups of PDD defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. In this study, PDD was divided into high-functioning autistic disorder (HFA) (n = 17) and other PDD (n = 11) consisting of Asperger's disorder (n = 8) and PDD-NOS (n = 3), and differences in mind-reading ability was examined between the two clinical groups and controls (n = 50) using a new advanced naturalistic task consisting of short scenes from a TV drama showing communication in social situations. The task was divided into visual and auditory tasks to investigate which modality was more valuable for individuals with PDD to understand the mental state of others. The results suggest that social cognition differs significantly between individuals with HFA and those with other PDD, with no difference being found between those with other PDD and controls. Neither the auditory or visual modality was found to be dominant in subjects with PDD in the mind-reading task. Taken together, complex mind-reading tasks appear to be effective for distinguishing individuals with HFA from those with other PDD.

Do the traits of autism-spectrum overlap with those of schizophrenia or obsessive-compulsive disorder in the general population? / Akio WAKABAYASHI in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)

Type de document : Texte imprimé et/ou numérique Auteurs : Akio WAKABAYASHI, Auteur ; Simon BARON-COHEN, Auteur ; Chris ASHWIN, Auteur Année de publication : 2012 Article en page(s) : p.717-725 Langues : Anglais (eng) Mots-clés : Autism-spectrum  Schizophrenia  Obsessive-compulsive disorder (OCD)  Autism-Spectrum Quotient (AQ)  Schizotypal Personality Questionnaire (SPQ)  Padua Inventory (PI) Index. décimale : PER Périodiques Résumé : Social and communicative deficits, restricted interests and repetitive behaviors are diagnostic features of autism spectrum disorders (ASD). The present study examined the relationship between autistic characteristics and schizophrenia-spectrum traits as well as between autistic characteristics and obsessive-compulsive traits in typically developed young adults. The Autism-Spectrum Quotient (AQ) was given separately to two large samples. In addition, one sample (N = 662) was given the Schizotypal Personality Questionnaire (SPQ) to assess schizophrenia-spectrum traits, whereas the other sample (N = 347) was given the Padua Inventory (PI) to assess obsessive-compulsive disorder (OCD) traits. The results revealed a moderate correlation between the AQ and the SPQ total scores; however, multiple regression analyses showed that the “Cognitive-Perceptual” factor did not predict the autism-spectrum degree, although autistic characteristics and schizophrenia-spectrum traits had common social–emotional difficulties. Similarly, there was a moderate correlation between the AQ and PI total scores, which suggests that they had common problems in cognitive aspects; however, autism-spectrum and OCD traits differed with regard to other behavioral characteristics including repetitive or impulsive behaviors. Therefore, there was not a large overlap of the autism-spectrum and either the schizophrenia- or obsessive-compulsive spectrums, although certain traits were correlated with each other.

Empathizing and Systemizing in Adults with and without Autism Spectrum Conditions: Cross-Cultural Stability / Akio WAKABAYASHI in Journal of Autism and Developmental Disorders, 37-10 (November 2007)

Three groups of participants took part: n = 48 people with autism spectrum, n = 137 general population controls, and n = 1,250 university student controls. Each participant completed the Empathy Quotient (EQ) and the Systemizing Quotient (SQ). Results: The autism spectrum condition (ASC) group scored significantly lower than controls on the EQ, and significantly higher on the SQ. Among both control groups, females scored significantly higher than males on the EQ, whilst males scored significantly higher than females on the SQ. The distribution of ‘brain types’, based on the difference between EQ and SQ scores, showed distinct profiles for people with ASC, control males and control females.

The Autism-Spectrum Quotient (AQ) Children’s Version in Japan: A Cross-Cultural Comparison / Akio WAKABAYASHI in Journal of Autism and Developmental Disorders, 37-3 (March 2007)

Assessment groups were: Group 1: n = 81 children with Asperger Syndrome (AS) or high-functioning autism (HFA); Group 2: n = 22 children diagnosed PDD-NOS with average IQ; and Group 3: n = 372 randomly selected controls from primary and secondary schools. Both clinical groups scored significantly higher than controls (AS/HFA mean AQ = 31.9, SD = 6.93; PDD-NOS mean AQ = 28.0, SD = 6.88; controls mean AQ = 11.7, SD = 5.94). Among the controls, males scored significantly higher than females. The pattern of difference between clinical groups and controls was found to be similar in both countries.
