Age and Sensory Processing Abnormalities Predict Declines in Encoding and Recall of Temporally Manipulated Speech in High-Functioning Adults with ASD / Jennifer L. MAYER in Autism Research, 7-1 (February 2014)  

Public ISBD [article]  inAutism Research > 7-1 (February 2014) . - p.40-49 Titre : Age and Sensory Processing Abnormalities Predict Declines in Encoding and Recall of Temporally Manipulated Speech in High-Functioning Adults with ASD Type de document : texte imprimé Auteurs : Jennifer L. MAYER, Auteur ; Pamela HEATON, Auteur Article en page(s) : p.40-49 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorders  Speech Perception  Auditory Processing  Aging Index. décimale : PER Périodiques Résumé : While temporal and perceptual processing abnormalities, identified in a number of electrophysiological and brain imaging studies of individuals with (ASD), are likely to impact on speech perception, surprisingly little is known about the behavioral outcomes of such abnormalities. It has been hypothesized that rapid temporal processing deficits may be linked to impaired language development through interference with acoustic information during speech perception. The present study aimed to investigate the impact of temporal changes on encoding and recall of speech, and the associated cognitive, clinical, and behavioral correlates in adults with ASD. Research carried out with typically developing (TD) adults has shown that word recall diminishes as the speed of speech increases, and it was predicted that the magnitude of this effect would be far greater in those with ASD because of a preexisting rapid temporal processing deficit. Nineteen high-functioning adults with ASD, and age- and intelligence-matched TD controls performed verbatim recall of temporally manipulated sentences. Reduced levels of word recall in response to increases in presentation speed were observed, and this effect was greater in the older participants in the ASD group than in the control group. This is the first study to show that both sensory abnormalities and aging impact on speech encoding in ASD. Auditory processing deficits in ASD may be indicative of an association with the sensory abnormalities and social and communication impairments characterizing the disorder.

Attentional shifting differences in autism: Domain general, domain specific or both? / Simona SKRIPKAUSKAITE in Autism, 25-6 (August 2021)

Type de document : texte imprimé Auteurs : Simona SKRIPKAUSKAITE, Auteur ; Lance SLADE, Auteur ; Jennifer L.

Yet, it is still unclear if this represents general visual differences (e.g. slower looking at any new information, social or not) or a uniquely social difference (e.g. only slower looking to humans but not objects). Here, we aimed to examine how quickly autistic and non-autistic adults look to and away from social (i.e. faces) and non-social information (i.e. squares and houses). We used an attentional shifting task with two images where sometimes the first image disappears before the new image appears (makes it easier to notice the new image) and other times it stays on the screen when the new image appears. In Experiment 1, we showed schematic faces and squares to 27 autistic and 26 non-autistic adults, and in Experiment 2, we showed photographs of faces and houses to 18 autistic and 17 non-autistic adults. In general, autistic adults looked at the new non-social or social images similarly to non-autistic adults. Yet, only autistic adults looked at new social information faster when the first image disappeared before the new image appeared. This shows that autistic individuals may find it easier to notice new social information if their attention is not already occupied.

Do Children With Autism Re-Enact Object Movements Rather Than Imitate Demonstrator Actions? / Deborah M. CUSTANCE in Autism Research, 7-1 (February 2014)  

Public ISBD [article]  inAutism Research > 7-1 (February 2014) . - p.28-39 Titre : Do Children With Autism Re-Enact Object Movements Rather Than Imitate Demonstrator Actions? Type de document : texte imprimé Auteurs : Deborah M. CUSTANCE, Auteur ; Jennifer L. MAYER, Auteur ; Emmelianna KUMAR, Auteur ; Elisabeth HILL, Auteur ; Pamela HEATON, Auteur Article en page(s) : p.28-39 Langues : Anglais (eng) Mots-clés : autism  imitation  emulation  transitive Index. décimale : PER Périodiques Résumé : It has been suggested that autism-specific imitative deficits may be reduced or even spared in object-related activities. However, most previous research has not sufficiently distinguished object movement reenactment (learning about the ways in which object move) from imitation (learning about the topography of demonstrated actions). Twenty children with autism (CWA) and 20 typically developing children (TDC) were presented with puzzle boxes containing prizes. Test objects and experimental conditions were designed to isolate object- and action-related aspects of demonstrations. There were four types of video demonstrations: (a) a full demonstration by an adult; (b) a ghost demonstration with object movements alone; (c) mimed solutions demonstrated adjacent to the objects; and (d) random actions performed on the surface of the objects. There were no significant between-group differences in the degree to which CWA and TDC matched the full demonstrations, the actual demonstrations or in their times to first solution in any of the conditions. Although there was no clear imitative deficit in the CWA, regression analyses were conducted to explore in more detail whether diagnosis, verbal intelligence quotient (VIQ), nonverbal IQ NVIQ, age or motor coordination predicted performance. The results are discussed in relation to the use of extrinsic vs. intrinsic rewards and the interplay between motor coordination and the relative rigidity vs. pliability of objects.

Mapping the Developmental Trajectory and Correlates of Enhanced Pitch Perception on Speech Processing in Adults with ASD / Jennifer L. MAYER in Journal of Autism and Developmental Disorders, 46-5 (May 2016)

This paper presents data on perception of complex tones and speech pitch in adult participants with high-functioning ASD and typical development, and compares these with pre-existing data using the same paradigm with groups of children and adolescents with and without ASD. As perceptual processing abnormalities are likely to influence behavioural performance, regression analyses were carried out on the adult data set. The findings revealed markedly different pitch discrimination trajectories and language correlates across diagnostic groups. While pitch discrimination increased with age and correlated with receptive vocabulary in groups without ASD, it was enhanced in childhood and stable across development in ASD. Pitch discrimination scores did not correlate with receptive vocabulary scores in the ASD group and for adults with ASD superior pitch perception was associated with sensory atypicalities and diagnostic measures of symptom severity. We conclude that the development of pitch discrimination, and its associated mechanisms markedly distinguish those with and without ASD.
