Face and Object Discrimination in Autism, and Relationship to IQ and Age / Pamela M. PALLETT in Journal of Autism and Developmental Disorders, 44-5 (May 2014)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 44-5 (May 2014) . - p.1039-1054 Titre : Face and Object Discrimination in Autism, and Relationship to IQ and Age Type de document : texte imprimé Auteurs : Pamela M. PALLETT, Auteur ; Shereen J. COHEN, Auteur ; Karen R. DOBKINS, Auteur Année de publication : 2014 Article en page(s) : p.1039-1054 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorders  Face processing  Object processing  Inversion effects  Adolescents  Development Index. décimale : PER Périodiques Résumé : The current study tested fine discrimination of upright and inverted faces and objects in adolescents with Autism Spectrum Disorder (ASD) as compared to age- and IQ-matched controls. Discrimination sensitivity was tested using morphed faces and morphed objects, and all stimuli were equated in low-level visual characteristics (luminance, contrast, spatial frequency make-up). Participants with ASD exhibited slight, non-significant impairments in discrimination sensitivity for faces, yet significantly enhanced discrimination sensitivity for objects. The ASD group also showed a protracted development of face and object inversion effects. Finally, for ASD participants, face sensitivity improved with increasing IQ while object sensitivity improved with age. By contrast, for controls, face sensitivity improved with age, but neither face nor object sensitivity was influenced by IQ. These findings suggest that individuals with ASD follow a qualitatively different path in the development of face and object processing abilities.

Increased Prevalence of Unusual Sensory Behaviors in Infants at Risk for, and Teens with, Autism Spectrum Disorder / Hannah M. VAN ETTEN in Journal of Autism and Developmental Disorders, 47-11 (November 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-11 (November 2017) . - p.3431-3445 Titre : Increased Prevalence of Unusual Sensory Behaviors in Infants at Risk for, and Teens with, Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Hannah M. VAN ETTEN, Auteur ; Maninderjit KAUR, Auteur ; Sudha M. SRINIVASAN, Auteur ; Shereen J. COHEN, Auteur ; Anjana N. BHAT, Auteur ; Karen R. DOBKINS, Auteur Article en page(s) : p.3431-3445 Langues : Anglais (eng) Mots-clés : Asd  High-risk siblings  Sensory atypicalities  Sensory processing  Sensory profile  Teenagers Index. décimale : PER Périodiques Résumé : The current study investigated the prevalence and pattern of unusual sensory behaviors (USBs) in teens with Autism Spectrum Disorder (ASD) and infants (3-36 months) at risk for ASD. From two different sites (UCSD and UConn), caregivers of infants at high (n = 32) and low risk (n = 33) for ASD, and teenagers with (n = 12) and without ASD (n = 11), completed age-appropriate Sensory Profile questionnaires (Infant/Toddler Sensory Profile; Dunn 2002; Adolescent/Adult Sensory Profile; Brown and Dunn 2002). The results show that high-risk infants and teenagers with ASD exhibit higher-than-typical prevalence of USBs. Results of our distribution analyses investigating the direction of sensory atypicalities (greater-than-typical vs. less-than-typical) revealed a fair degree of consistency amongst teens, however, USB patterns were more varied in high-risk infants.
