Atypical pattern separation memory and its association with restricted interests and repetitive behaviors in autistic children / Lang CHEN in Autism, 28-6 (June 2024)
[article]
Titre : Atypical pattern separation memory and its association with restricted interests and repetitive behaviors in autistic children Type de document : Texte imprimé et/ou numérique Auteurs : Lang CHEN, Auteur ; Jin LIU, Auteur ; Julia Boram KANG, Auteur ; Miriam ROSENBERG-LEE, Auteur ; Daniel A. ABRAMS, Auteur ; Vinod MENON, Auteur Article en page(s) : p.1503-1518 Langues : Anglais (eng) Mots-clés : ASD heterogeneity pattern separation recognition memory RRIB Index. décimale : PER Périodiques Résumé : Emerging research suggests that episodic memory challenges are commonly encountered by autistic individuals; however, the specific nature of these memory challenges remains elusive. Here, we address critical gaps in the literature by examining pattern separation memory, the ability to store distinct memories of similar stimuli, and its links to the core autistic trait of repetitive, restricted interests and behaviors. Utilizing a large sample of over 120 autistic children and well-matched non-autistic peers, we found that autistic children showed significantly reduced performance on pattern separation memory. A clustering analysis identified three distinct pattern separation memory profiles in autism, each characterized by reduced or increased generalization abilities. Importantly, pattern separation memory was negatively correlated with the severity of repetitive, restricted interest and behavior symptoms in autism. These findings offer new evidence for challenges in pattern separation memory in autism and emphasize the need to consider these challenges when assessing and supporting autistic individuals in educational and clinical settings. Lay abstract Memory challenges remain understudied in childhood autism. Our study investigates one specific aspect of memory function, known as pattern separation memory, in autistic children. Pattern separation memory refers to the critical ability to store unique memories of similar stimuli; however, its role in childhood autism remains largely uncharted. Our study first uncovered that the pattern separation memory was significantly reduced in autistic children, and then showed that reduced memory performance was linked to their symptoms of repetitive, restricted interest and behavior. We also identified distinct subgroups with profiles of reduced and increased generalization for pattern separation memory. More than 72% of autistic children showed a tendency to reduce memory generalization, focusing heavily on unique details of objects for memorization. This focus made it challenging for them to identify commonalities across similar entities. Interestingly, a smaller proportion of autistic children displayed an opposite pattern of increased generalization, marked by challenges in differentiating between similar yet distinct objects. Our findings advance the understanding of memory function in autism and have practical implications for devising personalized learning strategies that align with the unique memory patterns exhibited by autistic children. This study will be of broad interest to researchers in psychology, psychiatry, and brain development as well as teachers, parents, clinicians, and the wider public.

In this 6-year longitudinal study, we investigated the early cognitive predictors of reading skill in a statistically representative sample of Chinese children from Beijing.
Method: Two hundred sixty-one (261) native Chinese children were administered seven language-related skills over three years between the ages of 3 and 6 years. Performances on these skills were then examined in relation to subsequent word reading accuracy and fluency. Individual differences in developmental profiles across tasks were then estimated using growth mixture modeling.
Results: Four developmental trajectories were classified – the typical (control), catch-up (with low initial cognitive performances but adequate subsequent reading), literacy-related-cognitive-delay (with difficulties in morphological awareness, phonological awareness, and speeded naming and subsequent word recognition), and language-delay (relatively low across all tasks) groups.
Conclusion: Findings suggest that the combination of phonological awareness, rapid naming and morphological awareness are essential in the early prediction of later reading difficulties in Chinese children.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02311.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=116
