Face recognition performance of individuals with Asperger syndrome on the Cambridge face memory test / Darren HEDLEY in Autism Research, 4-6 (December 2011)  

Public ISBD [article]  inAutism Research > 4-6 (December 2011) . - p.449-455 Titre : Face recognition performance of individuals with Asperger syndrome on the Cambridge face memory test Type de document : texte imprimé Auteurs : Darren HEDLEY, Auteur ; Neil BREWER, Auteur ; Robyn L. YOUNG, Auteur Année de publication : 2012 Article en page(s) : p.449-455 Langues : Anglais (eng) Mots-clés : face recognition  autism spectrum disorder  Asperger syndrome  CFMT  face perception Index. décimale : PER Périodiques Résumé : Although face recognition deficits in individuals with Autism Spectrum Disorder (ASD), including Asperger syndrome (AS), are widely acknowledged, the empirical evidence is mixed. This in part reflects the failure to use standardized and psychometrically sound tests. We contrasted standardized face recognition scores on the Cambridge Face Memory Test (CFMT) for 34 individuals with AS with those for 42, IQ-matched non-ASD individuals, and age-standardized scores from a large Australian cohort. We also examined the influence of IQ, autistic traits, and negative affect on face recognition performance. Overall, participants with AS performed significantly worse on the CFMT than the non-ASD participants and when evaluated against standardized test norms. However, while 24% of participants with AS presented with severe face recognition impairment (>2 SDs below the mean), many individuals performed at or above the typical level for their age: 53% scored within +/− 1 SD of the mean and 9% demonstrated superior performance (>1 SD above the mean). Regression analysis provided no evidence that IQ, autistic traits, or negative affect significantly influenced face recognition: diagnostic group membership was the only significant predictor of face recognition performance. In sum, face recognition performance in ASD is on a continuum, but with average levels significantly below non-ASD levels of performance.

Brief Report: Developing Spatial Frequency Biases for Face Recognition in Autism and Williams Syndrome / Hayley C. LEONARD in Journal of Autism and Developmental Disorders, 41-7 (July 2011)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 41-7 (July 2011) . - p.968-973 Titre : Brief Report: Developing Spatial Frequency Biases for Face Recognition in Autism and Williams Syndrome Type de document : texte imprimé Auteurs : Hayley C. LEONARD, Auteur ; Dagmara ANNAZ, Auteur ; Annette KARMILOFF-SMITH, Auteur ; Mark H. JOHNSON, Auteur Année de publication : 2011 Article en page(s) : p.968-973 Langues : Anglais (eng) Mots-clés : Face recognition  Spatial frequency  Development  Autism  Williams syndrome Index. décimale : PER Périodiques Résumé : The current study investigated whether contrasting face recognition abilities in autism and Williams syndrome could be explained by different spatial frequency biases over developmental time. Typically-developing children and groups with Williams syndrome and autism were asked to recognise faces in which low, middle and high spatial frequency bands were masked. All three groups demonstrated a gradual specialisation toward the mid-band. However, while the use of high spatial frequencies decreased in control and autism groups over development, the Williams syndrome group did not display a bias toward this band at any point. These data demonstrate that typical outcomes can be achieved through atypical developmental processes, and confirm the importance of cross-syndrome studies in the investigation of developmental disorders.

Poor face recognition predicts social anxiety in autism: A short report / Bayparvah Kaur GEHDU in Autism, 28-11 (November 2024)  

Public ISBD [article]  inAutism > 28-11 (November 2024) . - p.2937 - 2942 Titre : Poor face recognition predicts social anxiety in autism: A short report Type de document : texte imprimé Auteurs : Bayparvah Kaur GEHDU, Auteur ; Katie L.H. GRAY, Auteur ; Richard COOK, Auteur Article en page(s) : p.2937 - 2942 Langues : Anglais (eng) Mots-clés : autism  face recognition  mental health  social anxiety Index. décimale : PER Périodiques Résumé : In the present study, we sought to examine whether face recognition problems impact the social anxiety experienced by autistic people. Many autistic people - perhaps between 15% and 30% - exhibit severe face recognition problems that closely resemble developmental prosopagnosia. At present, however, little is known about the psychosocial consequences of these difficulties. Autistic participants (N = 60) with varying degrees of face recognition ability completed two measures of face recognition (the original and Australian variants of the Cambridge Face Memory test), a measure of social anxiety (the Social Interaction Anxiety Scale) and a bespoke survey that enquired about individuals' experiences of face recognition and social interaction. Relative to autistic individuals with average or above-average face recognition, autistic individuals with poor face recognition described significantly higher levels of social anxiety. Moreover, more than half our participants felt that poor face recognition hampered their social interaction, while more than a third thought that poor face recognition had undermined their efforts to make friends. These initial results suggest that poor face recognition may be an important determinant of social anxiety in autism. Lay abstract Research has shown that some autistic people have severe difficulties in recognising other people?s faces. However, little is understood about how these difficulties impact the daily life and the mental well-being of autistic people. In this study, we asked 60 autistic adults with varying degrees of face recognition ability to complete two tests of face recognition, a questionnaire about social anxiety and a bespoke survey which asked participants about their experiences of face recognition and social interaction. We found that participants who had poor face recognition reported experiencing higher levels of social anxiety compared to those with average or better face recognition skills. More than half felt that their face recognition difficulties affected their social interactions, and over a third believed it hindered their ability to make friends. These findings suggest that face recognition difficulties may contribute to social anxiety among autistic individuals.

The Effect of Inversion on Face Recognition in Adults with Autism Spectrum Disorder / Darren HEDLEY in Journal of Autism and Developmental Disorders, 45-5 (May 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-5 (May 2015) . - p.1368-1379 Titre : The Effect of Inversion on Face Recognition in Adults with Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Darren HEDLEY, Auteur ; Neil BREWER, Auteur ; Robyn L.

In this study we examined the influence of inversion on face recognition in 26 adults with ASD and 33 age and IQ matched controls. Participants completed a recognition test comprising upright and inverted faces. Participants with ASD performed worse than controls on the recognition task but did not show an advantage for inverted face recognition. Both groups directed more visual attention to the eye than the mouth region and gaze patterns were not found to be associated with recognition performance. These results provide evidence of a normal effect of inversion on face recognition in adults with ASD.

Using Eye Movements as an Index of Implicit Face Recognition in Autism Spectrum Disorder / Darren HEDLEY in Autism Research, 5-5 (October 2012)  

Public ISBD [article]  inAutism Research > 5-5 (October 2012) . - p.363-379 Titre : Using Eye Movements as an Index of Implicit Face Recognition in Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Darren HEDLEY, Auteur ; Robyn L.

Performance has usually been assessed using overt, explicit recognition tasks. Here, a complementary method involving eye tracking was used to examine implicit face recognition in participants with ASD and in an intelligence quotient-matched non-ASD control group. Differences in eye movement indices between target and foil faces were used as an indicator of implicit face recognition. Explicit face recognition was assessed using old–new discrimination and reaction time measures. Stimuli were faces of studied (target) or unfamiliar (foil) persons. Target images at test were either identical to the images presented at study or altered by changing the lighting, pose, or by masking with visual noise. Participants with ASD performed worse than controls on the explicit recognition task. Eye movement-based measures, however, indicated that implicit recognition may not be affected to the same degree as explicit recognition.
