This capacity for relational binding is also involved in spatial navigation and research on this topic in ASD is scarce and inconclusive. Using a computerised version of the Morris Water Maze task, ASD participants showed particular difficulties in performing viewpoint independent (allocentric) navigation, leaving viewpoint dependent navigation (egocentric) intact. Further analyses showed that navigation deficits were not related to poor visual short-term memory or mental rotation in the ASD group. The results further confirm the need of autistic individuals for support at retrieval and have important implications for the design of signposts and maps.

An Eye-Movement Study of relational Memory in Adults with Autism Spectrum Disorder / Melanie RING in Journal of Autism and Developmental Disorders, 47-10 (October 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-10 (October 2017) . - p.2981-2991 Titre : An Eye-Movement Study of relational Memory in Adults with Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Melanie RING, Auteur ; Dermot M. BOWLER, Auteur ; Sebastian B. GAIGG, Auteur Article en page(s) : p.2981-2991 Langues : Anglais (eng) Mots-clés : Implicit and explicit memory  Relational memory  Autism Spectrum Disorder  Eye movements  Encoding and retrieval Index. décimale : PER Périodiques Résumé : Persons with Autism Spectrum Disorder (ASD) demonstrate good memory for single items but difficulties remembering contextual information related to these items. Recently, we found compromised explicit but intact implicit retrieval of object-location information in ASD (Ring et al. Autism Res 8(5):609–619, 2015). Eye-movement data collected from a sub-sample of the participants are the focus of the current paper. At encoding, trial-by-trial viewing durations predicted subsequent retrieval success only in typically developing (TD) participants. During retrieval, TD compared to ASD participants looked significantly longer at previously studied object-locations compared to alternative locations. These findings extend similar observations recently reported by Cooper et al. (Cognition 159:127–138, 2017a) and demonstrate that eye-movement data can shed important light on the source and nature of relational memory difficulties in ASD.

Arousal-modulated memory encoding and retrieval in adults with autism spectrum disorder / Nico BAST in Autism Research, 15-9 (September 2022)  

Public ISBD [article]  inAutism Research > 15-9 (September 2022) . - p.1609-1620 Titre : Arousal-modulated memory encoding and retrieval in adults with autism spectrum disorder Type de document : texte imprimé Auteurs : Nico BAST, Auteur ; Sebastian B. GAIGG, Auteur ; Dermot M. BOWLER, Auteur ; Veit ROESSNER, Auteur ; Christine M. FREITAG, Auteur ; Melanie RING, Auteur Article en page(s) : p.1609-1620 Langues : Anglais (eng) Mots-clés : Adult  Arousal/physiology  Autism Spectrum Disorder/complications  Humans  Locus Coeruleus  Pupil/physiology  Recognition, Psychology  Asd  locus coeruleus-norepinephrine system  memory  pupillometry Index. décimale : PER Périodiques Résumé : Recently, we have shown that pupil dilation during a recognition memory task can serve as an index of memory retrieval difficulties in autism. At the time of publication, we were unaware of specific data-analysis methods that can be used to shed further light on the origins of such memory related pupil dilation. Specifically, by distinguishing "tonic" from "phasic" changes in pupil dilation and considering their temporal progression, it is possible to draw inferences about the functional integrity of a locus coeruleus-norepinephrine system (LC-NE) that is known to play a key role in regulating memory encoding and retrieval processes. We therefore apply these analyses to our previously published eye-tracking data of adults with ASD (N = 24) and neurotypical development (TD, N = 30) during the recognition memory task. In this re-analysis, we related pupil dilation during encoding and retrieval to recognition accuracy in a per-trial analysis of linear mixed models. In ASD, we replicated attenuated recognition accuracy, which was accompanied by attenuated pupil dilation during encoding and retrieval. Group differences in pupil dilation during retrieval occurred late during the trial (after 1.75s) and indicated an altered top-down processing like attenuated attribution of semantic salience in response to previously encoded stimuli. In addition, only in the ASD group were higher pupil dilation during encoding and lower pupil dilation during retrieval associated with decreased recognition accuracy. This supports altered modulation of memory encoding and retrieval in ASD, with LC-NE phasic activity as promising underlying mechanism. LAY SUMMARY: We investigated the changes of pupil size during memory testing in autism spectrum disorder. Adults with ASD remembered fewer items correctly than neurotypical individuals (TD). This reduced memory was related to increased pupillary responses at study and decreased pupil dilation at test only for adults with ASD indicating a different modulation of memory by the locus coeruleus.

Assessing Anxiety in Autistic and Non-Autistic Youth: Validation of the German Parent Version of the Anxiety Scale for Children With Autism Spectrum Disorder / Magdalena GRUNER in Autism Research, 18-11 (November 2025)

The Anxiety Scale for Children with Autism Spectrum Disorder?Parent Version (ASC-ASD-P) was designed to address this issue, but its utility in German clinical settings has not been established. This study validated the German translation of the ASC-ASD-P in a clinical sample of 317 participants presenting at a clinic for autism assessment, including 120 autistic youth. Internal consistency was excellent (Cronbach's α?=?0.92), and convergent validity was demonstrated through significant correlations with established psychopathology measures such as the Child Behavior Checklist (CBCL) and Strengths and Difficulties Questionnaire (SDQ). Factor analyses preferred a 4-factor structure in the autism group, but indicated difficulties replicating the Separation Anxiety Subscale. Autistic youth showed higher total anxiety and uncertainty scores compared to non-autistic youth, underlining the scale's sensitivity to autism-specific anxiety patterns. By including youth with intellectual disabilities, often underrepresented in research, this study provides a more comprehensive evaluation of the ASC-ASD-P's applicability across the autism spectrum. These findings support the ASC-ASD-P as a reliable tool for assessing anxiety in German-speaking autistic youth while highlighting areas where refinement could strengthen its utility.

Capturing change in restricted and repetitive behaviour in preschoolers with ASD: A comparison of direct behavioural observation and parent report / Naisan RAJI in Journal of Child Psychology and Psychiatry, 66-11 (November 2025)

However, change sensitivity has not been systematically investigated among commonly used measures, albeit its importance for clinical trials and longitudinal studies. Methods Longitudinal data resulting from behavioural observation (Autism Diagnostic Observation Schedule-2, ADOS-2; Brief Observation of Social Communication Change, BOSCC) and parent report (Restricted Behaviour Scale-Revised, RBS-R) was collected for 134 toddlers and preschoolers aged 25?65?months diagnosed with ASD by the Autism Diagnostic Interview-Revised (ADI-R) and ADOS-2. Change sensitivity was estimated using the reliable-change index and developmental trajectories of RRB by linear mixed models and k-means clustering. Results The RBS-R identified significantly more reliable change in RRB severity compared to ADOS-2 and BOSCC. For all measures, except the RBS-R self-injurious behaviour subscale, three distinct RRB trajectories were found as follows: increasing, stable and decreasing RRB severity. Overlap was low between trajectory group assignment across measures, as were cross-sectional correlations between ADI-R, ADOS-2, BOSCC and RBS-R. Trajectory group comparisons among measures mostly showed lower baseline RRB severity in the increasing trajectory groups and higher baseline RRB severity in the decreasing trajectory groups. The trajectory groups did not differ in age or nonverbal IQ across RRB measures, except for the RBS-R compulsive behaviour subscale, which had higher nonverbal IQ in the decreasing trajectory group. Conclusions The dimensional questionnaire RBS-R compared to ADOS-2 and BOSCC is superior in capturing subtle changes in RRB during preschool age.
