The Influence of task Demands, Verbal Ability and Executive Functions on Item and Source Memory in Autism Spectrum Disorder / S. SEMINO in Journal of Autism and Developmental Disorders, 48-1 (January 2018)
[article]
Titre : The Influence of task Demands, Verbal Ability and Executive Functions on Item and Source Memory in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : S. SEMINO, Auteur ; M. RING, Auteur ; Dermot M. BOWLER, Auteur ; S. B. GAIGG, Auteur Article en page(s) : p.184-197 Langues : Anglais (eng) Mots-clés : Autism Executive function Item memory Recollection Source memory Verbal ability Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorder (ASD) is generally associated with difficulties in contextual source memory but not single item memory. There are surprising inconsistencies in the literature, however, that the current study seeks to address by examining item and source memory in age and ability matched groups of 22 ASD and 21 comparison adults. Results show that group differences in source memory are moderated by task demands but not by individual differences in verbal ability, executive function or item memory. By contrast, unexpected group differences in item memory could largely be explained by individual differences in source memory. These observations shed light on the factors underlying inconsistent findings in the memory literature in ASD, which has important implications for theory and practice.

Titre : Relational Memory Processes in Adults with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Melanie RING, Auteur ; Sebastian B. GAIGG, Auteur ; Dermot M. BOWLER, Auteur Article en page(s) : p.97-106 Langues : Anglais (eng) Mots-clés : item memory relational memory autism spectrum disorder ageing Index. décimale : PER Périodiques Résumé : Research into memory in Autism Spectrum Disorder (ASD) suggests intact item memory but difficulties in forming relations between items (Bowler, Gaigg, & Lind, 2011). In this study, we tested memory for items as well as for sequential, spatial, and associative relations between items with the same paradigm using abstract shapes in ASD and typically developing (TD) individuals. Participants studied shape triplets on a computer screen and memory was subsequently tested either for the individual items making up the triplets, the screen-locations, the order or the combinations of items presented at study. Contrary to our predictions, performance was significantly lower in the ASD group on all four tasks. The result raises questions about how intact item memory is in ASD, which role task complexity plays, and how item-specific versus relational processing affect task performance. One possibility is that TD individuals relied more on relational processing in the current study and might have therefore had an advantage over ASD individuals. This idea is supported by the result of a preliminary analysis of age-related differences in memory across the midadult lifespan in both groups. Age seems to affect order memory less in ASD compared with TD individuals where it leads to a significant decrease in performance. This might indicate a decrease in relational processing in TD but not ASD individuals with increasing age. More research is needed to answer questions about the change in cognition in ASD individuals across the lifespan.

Titre : Memory for Rules and Output Monitoring in Adults with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : K. YAMAMOTO, Auteur ; K. MASUMOTO, Auteur Article en page(s) : p.4780-4787 Langues : Anglais (eng) Mots-clés : Item memory Memory of rules Object arrangement task Output monitoring Repetition errors Restricted Index. décimale : PER Périodiques Résumé : This study examined factors related to repetitive errors in people with autism spectrum disorder (ASD) from the perspective of output monitoring and memory for rules. Previous studies have suggested that output monitoring errors are associated with repetition errors. Moreover, people with ASD have a reduced memory for rules, which could result in repetitive errors. Typically developing (TD) and ASD participants memorized rules and conducted an object arrangement task consisting of sorting objects according to their price under two conditions. Memory tests and output monitoring tests were conducted immediately, and 1 week later. Results indicated that output monitoring in ASD was significantly lower than in TD, although the memory for rules showed no differences between ASD and TD.

Titre : Episodic Recollection Difficulties in ASD Result from Atypical Relational Encoding: Behavioral and Neural Evidence Type de document : Texte imprimé et/ou numérique Auteurs : Sebastian B. GAIGG, Auteur ; Dermot M. BOWLER, Auteur ; Christine ECKER, Auteur ; Beatriz CALVO-MERINO, Auteur ; Declan G. MURPHY, Auteur Article en page(s) : p.317-327 Langues : Anglais (eng) Mots-clés : autism relational memory item memory recollection familiarity Index. décimale : PER Périodiques Résumé : Memory functioning in Autism Spectrum Disorder (ASD) is characterized by impairments in the encoding of relational but not item information and difficulties in the recollection of contextually rich episodic memories but not in the retrieval of relatively context-free memories through processes of familiarity. The neural underpinnings of this profile and the extent to which encoding difficulties contribute to retrieval difficulties in ASD remain unclear. Using a paradigm developed by Addis and McAndrews [2006; Neuroimage, 33, 1194–1206] we asked adults with and without a diagnosis of ASD to study word-triplets during functional Magnetic Resonance Imaging (fMRI) scanning that varied in the number of category relations amongst component words. Performance at test confirmed attenuated recollection in the context of preserved familiarity based retrieval in ASD. The results also showed that recollection but not familiarity based retrieval increases as a function of category relations in word triads for both groups, indicating a close link between the encoding of relational information and recollection. This link was further supported by the imaging results, where blood oxygen level dependent (BOLD) signal responses in overlapping regions of the inferior prefrontal cortex were sensitive to the relational encoding manipulation as well as the contrast between recollection versus familiarity based retrieval. Interestingly, however, there was no evidence of prefrontal signal differentiation for this latter contrast in the ASD group for whom signal changes in a left hippocampal region were also marginally attenuated. Together, these observations suggest that attenuated levels of episodic recollection in ASD are, at least in part, attributable to anomalies in relational encoding processes.
