Stimulus Over-Selectivity and Extinction-Induced Recovery of Performance as a Product of Intellectual Impairment and Autism Severity / Michelle P. KELLY in Journal of Autism and Developmental Disorders, 45-10 (October 2015)
[article]
Titre : Stimulus Over-Selectivity and Extinction-Induced Recovery of Performance as a Product of Intellectual Impairment and Autism Severity Type de document : Texte imprimé et/ou numérique Auteurs : Michelle P. KELLY, Auteur ; Geraldine LEADER, Auteur ; Phil REED, Auteur Article en page(s) : p.3098-3106 Langues : Anglais (eng) Mots-clés : Over-selectivity Extinction Comparator deficit Intellectual impairment Autism severity Index. décimale : PER Périodiques Résumé : The current experiment investigated the extent to which three variables (autism severity, nonverbal intellectual functioning, and verbal intellectual functioning) are associated with over-selective responding in a group of children with Autism Spectrum Disorder. This paper also analyzed the association of these three variables with the recovery of responding to a previously under-selected stimulus following extinction of the previously over-selected stimulus. The results demonstrated that participants showed over-selectivity, and demonstrated that extinction of the over-selected stimulus led to recovery of responding to the previously under-selected stimulus. For both over-selectivity, and recovery from over-selectivity, verbal functioning appeared to predict the effects most strongly, with greater over-selectivity in the lower functioning individuals, and greater recovery in the higher functioning individuals.

Titre : Facilitating Neurofeedback in Children with Autism and Intellectual Impairments Using TAGteach Type de document : Texte imprimé et/ou numérique Auteurs : K. LAMARCA, Auteur ; R. GEVIRTZ, Auteur ; A. J. LINCOLN, Auteur ; J. A.

This study focuses on using Teaching with Acoustic Guidance-TAGteach-to behaviorally prepare children with autism and a IQ = 80 to participate in a study on neurofeedback training (NFT). Seven children (ages 6-8) learned the prerequisite skills identified in a task analysis in an average of 5 h of TAGteach training, indicating that this is a feasible method of preparing intellectually-impaired children with autism to participate in NFT and task-dependent electroencephalography measures. TAGteach may thus have the potential to augment this population's ability to participate in less accessible treatments and behavioral neuroscientific studies.

Titre : Using the AQ-10 with adults who have a borderline or mild intellectual disability: Pilot analysis of an adapted AQ-10 (AQ-10-Intellectual Disability) Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth C. KENT, Auteur ; Gerald H. BURGESS, Auteur ; Elizabeth KILBEY, Auteur Article en page(s) : p.65-75 Langues : Anglais (eng) Mots-clés : Intellectual disability Autism spectrum disorder Intellectual impairment Screening Case identification AQ-10 Index. décimale : PER Périodiques Résumé : Background There is a need for appropriate screening tools for case identification of autism spectrum disorder (ASD) in those with intellectual disabilities (ID) given the high co-occurrence of the two conditions. The AQ-10 is the screening tool recommended by NICE for the identification of ASD in adults with a borderline or mild intellectual disability. However, the AQ-10 was not developed with this population in mind. Method A mixed-methods approach was used to investigate the utility of the AQ-10 in its original form as a case identification tool. The AQ-10 was then redesigned and piloted. Qualitative results revealed individuals with a borderline or mild ID found the AQ-10 too inaccessible in its current format. Results Following revision, the diagnostic validity of the revised measure (AQ-10-ID) showed good sensitivity (0.85) and specificity (0.77), whereas the diagnostic validity of the original AQ-10 was poor. The internal consistency for the AQ-10-ID was 0.67 and 0.30 for the AQ-10. Conclusions These findings indicate that changes may be needed to the AQ-10 before clinicians consider using as a screen tools for adults with an intellectual disability.

Titre : Examination of Stimulus Over-Selectivity in Children With Autism Spectrum Disorder and Its Relationship to Stereotyped Behaviors and Cognitive Flexibility Type de document : Texte imprimé et/ou numérique Auteurs : M. P. KELLY, Auteur ; P. REED, Auteur Article en page(s) : p.47-56 Langues : Anglais (eng) Mots-clés : stimulus over-selectivity stereotyped behavior cognitive flexibility set shifting intellectual impairment Index. décimale : PER Périodiques Résumé : Stimulus over-selectivity describes a phenomenon in which an individual responds only to a subset of the stimuli present in the environment and, thus, may restrict learning. This study aimed to develop understanding of the nature and role of over-selectivity in autism spectrum disorder (ASD) by analyzing the relationship of over-selectivity to core deficits of ASD: stereotyped responding and inflexibility. Over-selectivity was investigated in a visual discrimination task in 24 children, 12 diagnosed with ASD and 12 mental-age-matched typically developing children. In addition, the participants’ levels of intellectual functioning, stereotypy, and cognitive flexibility were assessed using established tools. Results showed that over-selectivity was associated with IQ and stereotyped behavior but was not related to levels of cognitive flexibility nor did cognitive flexibility significantly correlate with stereotyped behavior in individuals with ASD. The current findings require consideration when designing behavioral interventions for individuals with ASD.

PMS typically results from a deletion of the distal long arm of chromosome 22, with the size of the deleted segment ranging from less than 100 kb to greater than 9 MB. The loss of 22q13 may result from a terminal deletion, an interstitial deletion, an unbalanced translocation, formation of a ring chromosome, or other types of structural chromosome aberrations. In most cases, the deletion results in haploinsufficiency for the SHANK3 gene which codes for a scaffolding protein in the postsynaptic density of excitatory neurons. Mutation or disruption of the SHANK3 gene may also result in PMS. The diagnosis of PMS relies on laboratory confirmation by molecular cytogenetic or molecular genetic methods.
