ADHD and delay aversion: the influence of non-temporal stimulation on choice for delayed rewards / Inge ANTROP in Journal of Child Psychology and Psychiatry, 47-11 (November 2006)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 47-11 (November 2006) . - p.1152–1158 Titre : ADHD and delay aversion: the influence of non-temporal stimulation on choice for delayed rewards Type de document : texte imprimé Auteurs : Inge ANTROP, Auteur ; Herbert ROEYERS, Auteur ; Dieter BAEYENS, Auteur ; Pieter STOCK, Auteur ; Sylvie VERTE, Auteur ; Jan R. WIERSEMA, Auteur Année de publication : 2007 Article en page(s) : p.1152–1158 Langues : Anglais (eng) Mots-clés : Delay-aversion Index. décimale : PER Périodiques Résumé : Background: Delay aversion, the motivation to escape or avoid delay, results in preference for small immediate over large delayed rewards. Delay aversion has been proposed as one distinctive psychological process that may underlie the behavioural symptoms and cognitive deficits of attention deficit/hyperactivity disorder (ADHD). Furthermore, the delay aversion hypothesis predicts that ADHD children's preference for immediate small over large delayed rewards will be reduced when stimulation, which makes time appear to pass more quickly, is added to the delay interval. The current paper tests these predictions. Methods: A group of children with a diagnosis of ADHD (with or without oppositional defiant disorder (ODD)), a group with a diagnosis of high-functioning autism (HFA), and a normal control group were compared on an experimental paradigm giving repeated choices between small immediate and large delayed rewards (Maudsley Index of Delay Aversion–MIDA) under two conditions (stimulation and no stimulation). Results: As predicted, ADHD children displayed a stronger preference than the HFA and control children for the small immediate rewards under the no-stimulation condition. The ADHD children preferences were normalised under the stimulation condition with no differences between the groups. This pattern of results was the same whether the ADHD children had comorbid ODD or not. Discussion: The findings from the MIDA are consistent with the delay aversion hypothesis of ADHD in showing that preference for small immediate rewards over large delayed rewards is a specific feature of ADHD and that this preference can be reduced by the addition of stimulation. Further research is required to better understand the emotional and motivational mechanisms underpinning delay aversion.

Adults with Autism Prefer Person-First Language in Dutch: A Cross-Country Study / Annabel D. NIJHOF ; Jan R. WIERSEMA in Journal of Autism and Developmental Disorders, 55-6 (June 2025)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 55-6 (June 2025) . - p.2027-2033 Titre : Adults with Autism Prefer Person-First Language in Dutch: A Cross-Country Study Type de document : texte imprimé Auteurs : Annabel D. NIJHOF, Auteur ; Jan R. WIERSEMA, Auteur Article en page(s) : p.2027-2033 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The correct language to refer to someone with a diagnosis of autism spectrum disorder has received a lot of attention in recent years. Studies in English-speaking countries found a main identity-first language (IFL) preference (e.g. autistic person) opposed to a person-first language preference (PFL) (e.g. person with autism) among adults with autism. However, a recent study conducted in a Dutch-speaking country (the Netherlands) reported a PFL preference (Buijsman et al., 2023). The goal of the current study was to gain insights into language preferences in two Dutch-speaking countries and, in contrast to previous studies, give participants the option to indicate not having a specific language preference. In the current study, we asked 414 Dutch-speaking adults with autism, living either in Belgium or the Netherlands, to fill in an online questionnaire about their language preference. We found that over half of the participants had a PFL preference (54%), followed by having no preference (27%). Only 14% of them had an IFL preference, and 5% proposed another term. Having more years of education was identified as a predictor for having an IFL preference when compared to a PFL preference, while being older predicted having no preference compared to a PFL preference. The majority of Dutch-speaking adults with autism showed a PFL preference, which is in contrast to findings from English-speaking countries, but in accord with a recent study conducted in the Netherlands (Buijsman et al., 2023). Implications of this finding for language use are discussed.

Adults with autism’s communication preferences with others with and without autism: A mixed-methods study / Hannah DE LAET in Research in Autism, 131 (March 2026)  

Public ISBD [article]  inResearch in Autism > 131 (March 2026) . - 202814 Titre : Adults with autism’s communication preferences with others with and without autism: A mixed-methods study Type de document : texte imprimé Auteurs : Hannah DE LAET, Auteur ; Annabel D. NIJHOF, Auteur ; Jan R. WIERSEMA, Auteur Article en page(s) : 202814 Langues : Anglais (eng) Mots-clés : Autism  Double empathy problem  Interaction  Mixed-method study Index. décimale : PER Périodiques Résumé : While prevailing theories suggest social interaction difficulties are inherent to individuals with autism, the theory of the double empathy problem proposes that these difficulties result from a mismatch between neurologically different interaction partners. This theory also predicts less difficulty during interaction between individuals with autism. Existing studies enquiring the experiences of individuals with autism indeed suggest that they consider interaction with others with autism as easier. However, studies directly assessing experiences are scarce and often involve small sample sizes, warranting further investigation. In this study, adults with autism completed an online mixed-method questionnaire, consisting of 14 statements (N = 407) comparing various aspects of interaction between individuals with and without autism and six open-ended questions (N = 337). The statements revealed that adults with autism experienced all, except for one, aspects of communication to be better and easier with others who also have autism than with others who do not. The only aspect of communication they did not experience to be better was body language. The open-ended questions’ results mainly support the findings from the statements, but also provide additional nuance. Themes highlighted easier interactions between individuals with autism, characterized by mutual understanding and absence of judgment. Additionally, when they know someone also has autism, they feel less need to camouflage. However, some interaction difficulties were also noted. In conclusion, the experiences of adults with autism in our study align with the theory of the double empathy problem, however further systematic research is warranted to test this theory.

Autistic traits are related to worse performance in a volatile reward learning task despite adaptive learning rates / Judith GORIS in Autism, 25-2 (February 2021)

Here, we investigated this hypothesis by estimating learning rates (i.e. the speed with which one learns) in three different environments that differed in rule stability and uncertainty. We found that neurotypical participants with more autistic traits performed worse in a volatile environment (with unstable rules), as they chose less often for the most rewarding option. Exploratory analyses indicated that performance was specifically worse when reward rules were opposite to those initially learned for participants with more autistic traits. However, there were no differences in the adjustment of learning rates between participants with more versus less autistic traits. Together, these results suggest that performance in volatile environments is lower in participants with more autistic traits, but that this performance difference cannot be unambiguously explained by an impairment in adjusting learning rates.

Different exploration strategies along the autism spectrum: diverging effects of autism diagnosis and autism traits / Fien GOETMAECKERS in Molecular Autism, 16 (2025)

Consent for  publication: Not applicable. Competing interests: The authors declare no  competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: When faced with many options to choose from, humans typically need to explore the utility of new choice options. People with an autism diagnosis or elevated autism traits are thought to avoid exploring such unknown options, but it remains unclear how autism affects exploration in decision spaces with many options. METHODS: In a large online sample (N = 588), we investigated the impact of autism diagnosis or elevated autism traits on exploration behavior during value-based decision-making in vast decision spaces. We used a 121-armed bandit with spatially correlated choice options, and a dedicated computational model to disentangle generalization, uncertainty-guided exploration, and random exploration strategies. RESULTS: Our findings show that participants with a self-reported autism diagnosis were less likely to explore novel choice options and more likely to exploit known high-value options. Computational modeling suggests they engaged in less uncertainty-driven exploration but exhibited equal random exploration and generalization strategies. Interestingly, among non-diagnosed participants, people with elevated autism traits did not explore less. LIMITATIONS: This study relies on self-reported autism diagnoses and trait measures collected online. This may limit the generalizability of the findings to clinically verified or more diverse autism populations. CONCLUSIONS: Our findings highlight important differences in exploration strategies between clinical and subclinical populations and emphasize the importance of cognitive modeling and using vast decision spaces to better understand autism.
