Categorizing the cries of infants with ASD versus typically developing infants: A study of adult accuracy and reaction time / Marc H. BORNSTEIN in Research in Autism Spectrum Disorders, 31 (November 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 31 (November 2016) . - p.66-72 Titre : Categorizing the cries of infants with ASD versus typically developing infants: A study of adult accuracy and reaction time Type de document : texte imprimé Auteurs : Marc H. BORNSTEIN, Auteur ; K. COSTLOW, Auteur ; A. TRUZZI, Auteur ; Gianluca ESPOSITO, Auteur Article en page(s) : p.66-72 Langues : Anglais (eng) Mots-clés : Cry  Infancy  Autism spectrum disorder  Typical development  Vocalizations  Reaction time Index. décimale : PER Périodiques Résumé : AbstractBackground The cries of children with Autism Spectrum Disorder (ASD) contain atypical acoustic features. The cries of typically developing infants elicit automatic adult responses, but little is known about how the atypical cries of children with ASD affect the speed with which adults process them. Method. We used a reaction time (RT) categorical task to analyze adults’ categorization of typically developing cries, atypical (ASD) cries, mammalian animal cries, and environmental noise control sounds. 40 nonparent women (M age = 27 years) were instructed to categorize acoustic stimuli as human infant cries or non-human sounds as quickly as possible. Results. The RTs for correctly categorizing the cries of children with ASD (M = 831 ms, SEM = 27) were slower than RTs for typically developing child cries (M = 680 ms, SEM = 6) as well as mammalian animal cries (801 ms, SEM = 11) and environmental noise control sounds (M = 692 ms, SEM = 10). Conclusions. This difference may reflect difficulties in adults’ perceiving and processing atypical cries of children with ASD, and the findings may have implications for the parent-child relationship and for the quality of care children with ASD receive.

Focused attention in late-diagnosed adults with autism spectrum disorder – A matter of reaction time? / Stefanie GROBA in Research in Autism, 131 (March 2026)  

Public ISBD [article]  inResearch in Autism > 131 (March 2026) . - 202806 Titre : Focused attention in late-diagnosed adults with autism spectrum disorder – A matter of reaction time?

As deficits in basic attentional functions, in addition to core behavioral characteristics, have been associated with ASD in children and adolescents, this study examined focused attentional profiles in adults with late-diagnosed ASD without intellectual disability and compared them to a matched non-autistic control group (NC) using the Test Battery for Attention Performance (TAP). The study included 37 individuals with ASD (17 females, 20 males; mean age 33.57 ± 10.2 y) and 34 NC (18 females, 16 males; 34.0 ± 11.02 y). While qualitative performance indicators did not differ significantly, adults with ASD consistently showed longer reaction times on most TAP tests reflecting focused attention. Controlling for co-occurring depression and attention deficit hyperactivity disorder, reaction time on the TAP working memory task was found to be a potential discriminator between ASD and NC, albeit with modest discriminative power. In contrast to findings in children and adolescents with ASD, adults with ASD showed temporal rather than qualitative performance deficits, suggesting a possible speed-accuracy trade-off. These findings contribute to the understanding of attentional mechanisms in adults with ASD by highlighting the importance of temporal processing in attentional tasks and suggest implications for diagnostic assessment, intervention, and remediation.

Increased reaction time variability in attention-deficit hyperactivity disorder as a response-related phenomenon: evidence from single-trial event-related potentials / Christopher W.N. SAVILLE in Journal of Child Psychology and Psychiatry, 56-7 (July 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-7 (July 2015) . - p.801-813 Titre : Increased reaction time variability in attention-deficit hyperactivity disorder as a response-related phenomenon: evidence from single-trial event-related potentials Type de document : texte imprimé Auteurs : Christopher W.N. SAVILLE, Auteur ; Bernd FEIGE, Auteur ; Christian KLUCKERT, Auteur ; Stephan BENDER, Auteur ; Monica BISCALDI, Auteur ; Andrea BERGER, Auteur ; Christian FLEISCHHAKER, Auteur ; Klaus HENIGHAUSEN, Auteur ; Christoph KLEIN, Auteur Article en page(s) : p.801-813 Langues : Anglais (eng) Mots-clés : ADHD  EEG  reaction time  working memory  event-related potential Index. décimale : PER Périodiques Résumé : Background Increased intra-subject variability (ISV) in reaction times (RTs) is a promising endophenotype for attention-deficit hyperactivity disorder (ADHD) and among the most robust hallmarks of the disorder. ISV has been assumed to represent an attentional deficit, either reflecting lapses in attention or increased neural noise. Here, we use an innovative single-trial event-related potential approach to assess whether the increased ISV associated with ADHD is indeed attributable to attention, or whether it is related to response-related processing. Methods We measured electroencephalographic responses to working memory oddball tasks in patients with ADHD (N = 20, aged 11.3 ± 1.1) and healthy controls (N = 25, aged 11.7 ± 1.1), and analysed these data with a recently developed method of single-trial event-related potential analysis. Estimates of component latency variability were computed for the stimulus-locked and response-locked forms of the P3b and the lateralised readiness potential (LRP). Results ADHD patients showed significantly increased ISV in behavioural ISV. This increased ISV was paralleled by an increase in variability in response-locked event-related potential latencies, while variability in stimulus-locked latencies was equivalent between groups. This result held across the P3b and LRP. Latency of all components predicted RTs on a single-trial basis, confirming that all were relevant for speed of processing. Conclusions These data suggest that the increased ISV found in ADHD could be associated with response-end, rather than stimulus-end processes, in contrast to prevailing conceptions about the endophenotype. This mental chronometric approach may also be useful for exploring whether the existing lack of specificity of ISV to particular psychiatric conditions can be improved upon.

ASD individuals showed impaired spatial working memory, whereas planning, cognitive flexibility, and inhibition were spared. Pure movement execution during visuo-motor information processing also was intact. In contrast, execution time of reading, naming, and of visuo-motor information processing tasks including a choice component was increased in the ASD group. Results of this study are in line with previous studies reporting only minimal EF difficulties in older individuals with ASD when assessed by computerized tasks. The finding of impaired visuo-motor information processing should be accounted for in further neuropsychological studies in ASD.

Mutations in neuroligin-3 in male mice impact behavioral flexibility but not relational memory in a touchscreen test of visual transitive inference / Rebecca H.C. NORRIS in Molecular Autism, 10 (2019)

Titre : Mutations in neuroligin-3 in male mice impact behavioral flexibility but not relational memory in a touchscreen test of visual transitive inference Type de document : texte imprimé Auteurs : Rebecca H.C. NORRIS, Auteur ; Leonid CHURILOV, Auteur ; Anthony J. HANNAN, Auteur ; Jess NITHIANANTHARAJAH, Auteur Article en page(s) : 42 p. Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Perseveration  Processing speed  Reaction time  Synapse Index. décimale : PER Périodiques Résumé : Cognitive dysfunction including disrupted behavioral flexibility is central to neurodevelopmental disorders such as Autism Spectrum Disorder (ASD). A cognitive measure that assesses relational memory, and the ability to flexibly assimilate and transfer learned information is transitive inference. Transitive inference is highly conserved across vertebrates and disrupted in cognitive disorders. Here, we examined how mutations in the synaptic cell-adhesion molecule neuroligin-3 (Nlgn3) that have been documented in ASD impact relational memory and behavioral flexibility. We first refined a rodent touchscreen assay to measure visual transitive inference, then assessed two mouse models of Nlgn3 dysfunction (Nlgn3 (-/y) and Nlgn3 (R451C)). Deep analysis of touchscreen behavioral data at a trial level established we could measure trajectories in flexible responding and changes in processing speed as cognitive load increased. We show that gene mutations in Nlgn3 do not disrupt relational memory, but significantly impact flexible responding. Our study presents the first analysis of reaction times in a rodent transitive inference test, highlighting response latencies from the touchscreen system are useful indicators of processing demands or decision-making processes. These findings expand our understanding of how dysfunction of key components of synaptic signaling complexes impact distinct cognitive processes disrupted in neurodevelopmental disorders, and advance our approaches for dissecting rodent behavioral assays to provide greater insights into clinically relevant cognitive symptoms.
