Timing and Intertemporal Choice Behavior in the Valproic Acid Rat Model of Autism Spectrum Disorder / William E. DECOTEAU in Journal of Autism and Developmental Disorders, 52-6 (June 2022)
[article]
Titre : Timing and Intertemporal Choice Behavior in the Valproic Acid Rat Model of Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : William E. DECOTEAU, Auteur ; Adam E. FOX, Auteur Article en page(s) : p.2414-2429 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD) Delay discounting Rats Time perception Timing Valproic Acid Index. décimale : PER Périodiques Résumé : Recently it has been proposed that impairments related to autism spectrum disorder (ASD) may reflect a more fundamental disruption in time perception. Here, we examined whether in utero exposure to valproic acid (VPA) can generate specific behavioral deficits related to ASD and time perception. Pups from control and VPA groups were tested using fixed-interval (FI) temporal bisection, peak interval, and intertemporal choice tasks. In addition, the rats were assessed on motor function, perseverative and exploratory behavior, anxiety, and memory. The VPA group displayed a leftward shift in timing functions. VPA rats displayed no deficits on the motor and memory tasks, but were significantly different from controls on measures of perseveration and anxiety.

Titre : Timing deficits are implicated in motor dysfunction in Asperger's Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Kelly J. PRICE, Auteur ; Dorothy EDGELL, Auteur ; Kimberly A. KERNS, Auteur Année de publication : 2012 Article en page(s) : p.857-860 Langues : Anglais (eng) Mots-clés : Asperger Autism Motor Movement Timing Perception Index. décimale : PER Périodiques Résumé : This study addressed what role movement timing irregularities have in producing the motor deficits documented in Asperger's Syndrome (AS). Participants included males with AS (n = 14) and without (n = 16), matched by age (7–23 years) and with no significant IQ differences. They completed measures of timing perception (comparisons of tempo of tones) and production (rhythmic finger tapping), and general motor skills (Dean–Woodcock Neuropsychological Battery motor tests). No central timing difficulties were noted, but the AS group showed more irregularity in motor implementation (with a large effect size), and this irregularity correlated with general motor skills.

Titre : Temporal preparation in adults with autistic spectrum disorder: The variable foreperiod effect Type de document : Texte imprimé et/ou numérique Auteurs : G. GIRARDI, Auteur ; L. G. FERNANDEZ, Auteur ; M. LEBOYER, Auteur ; A. LATIMIER, Auteur ; S. CHOKRON, Auteur ; T. ZALLA, Auteur Article en page(s) : p.2393-2404 Langues : Anglais (eng) Mots-clés : Adult Attention Autism Spectrum Disorder Cognition Humans Reaction Time Time Perception arousal conditional probability foreperiod implicit temporal preparation timing Index. décimale : PER Périodiques Résumé : Research suggested the possibility that temporal cognition may be different in autistic spectrum disorder (ASD). Although there are some empirical studies examining timing ability in these individuals, to our knowledge, no one directly assessed the ability to predict when an event will occur. Here, we report a study on implicit temporal preparation in individuals with ASD as indexed by the variable foreperiod (FP) effect. We compared a group of adult ASD participants to a group of typically-developed (TD) controls, for their respective abilities to utilize implicit temporal information in a simple detection task with three different preparatory intervals (FP, short, middle and long). Participants were given a warning tone to signal an imminent stimulus, and asked to press a key as quickly as they could upon detection of the stimulus. Both groups were able to use implicit temporal information, as revealed by both the variable-FP effect (i.e., faster response for targets appearing after a long FP) and asymmetric sequential effects (i.e., slower response in short-FP trials following a previous long-FP trial). The TD group exhibited a faster response in a long-FP trial that was preceded by short-FP one, whereas the ASD group did not, as reflected in their higher percentage of response omissions for a target that appeared later than in the previous trial. The reduced ability of ASD participants to modulate their responses under these conditions might reflect a difficulty in time-based monitoring of stimulus occurrence. LAY SUMMARY: Time-processing may be different in autistic spectrum disorder (ASD). This study addressed the ability to anticipate a relevant stimulus's onset according to predictable interstimulus intervals comparing adults with ASD and typically developed controls. We found that ASD participants did not benefit from temporal preparation when stimulus appeared later than previously attended. This suggests a reduced ability in detecting implicit temporal regularities between events.

Titre : Time perception and autistic spectrum condition: A systematic review Type de document : Texte imprimé et/ou numérique Auteurs : M. CASASSUS, Auteur ; E. POLIAKOFF, Auteur ; E. GOWEN, Auteur ; D. POOLE, Auteur ; L. A. JONES, Auteur Article en page(s) : p.1440-1462 Langues : Anglais (eng) Mots-clés : autism prospective timing scalar expectancy theory systematic review temporal order judgements temporal sensitivity time perception timing Index. décimale : PER Périodiques Résumé : Problems with timing and time perception have been suggested as key characteristics of autism spectrum condition (ASC). Studies and personal accounts from clinicians, parents, caregivers, and self-reports from autistic people themselves often refer to problems with time. Although a number of empirical studies have examined aspects relating to time in autistic individuals, there remains no clear consensus on whether or how timing mechanisms may be affected in autism. A key reason for this lack of clarity is the wide range of timing processes that exist and subsequently the wide range of methodologies, research paradigms, and samples that time-based studies have used with autism populations. In order to summarize and organize the available literature on this issue, a systematic review was conducted. Five electronic databases were consulted. From an initial 597 records (after duplicates were removed), 45 papers were selected and reviewed. The studies are reviewed within different sections based on the different types of timing ability that have been explored in the neurotypical (NT) population: time sensitivity, interval timing, and higher-order time perception. Within each section cognitive models, methodologies, possible clinical implications, and research results are discussed. The results show different consistency across studies between the three types of timing ability. The highest consistency of results showing atypical time perception abilities is found in high-level time perception studies. It remains unclear if autism is characterized by a fundamental time perception impairment. Suggestions for future research are discussed. Autism Res 2019, 12: 1440-1462. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This systematic review examines the different types of timing and time perception behavior that have been investigated in autism. Overall, there are a number of studies that show differences between autistic and non-autistic individuals, but some studies do not find such differences. Group differences are more consistent across studies using complex tasks rather than simpler more fundamental timing tasks. We suggest that experiments across a range of timing tasks would be fruitful to address gaps in our knowledge.

Titre : Interceptive skills in children aged 9–11 years, diagnosed with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Caroline P. WHYATT, Auteur ; Cathy M. CRAIG, Auteur Article en page(s) : p.613-623 Mots-clés : Catching Tau-coupling Motor Control Timing ASD Index. décimale : PER Périodiques Résumé : Growing evidence suggests that significant motor problems are associated with a diagnosis of Autism Spectrum Disorders (ASD), particularly in catching tasks. Catching is a complex, dynamic skill that involves the ability to synchronise one's own movement to that of a moving target. To successfully complete the task, the participant must pick up and use perceptual information about the moving target to arrive at the catching place at the right time. This study looks at catching ability in children diagnosed with ASD (mean age 10.16 ± 0.9 years) and age-matched non-verbal (9.72 ± 0.79 years) and receptive language (9.51 ± 0.46) control groups. Participants were asked to “catch” a ball as it rolled down a fixed ramp. Two ramp heights provided two levels of task difficulty, whilst the sensory information (audio and visual) specifying ball arrival time was varied. Results showed children with ASD performed significantly worse than both the receptive language (p = .02) and non-verbal (p = .02) control groups in terms of total number of balls caught. A detailed analysis of the movement kinematics showed that difficulties with picking up and using the sensory information to guide the action may be the source of the problem.
