Assessing Recollection and Familiarity in Low Functioning Autism / Susan NI CHUILEANN in Journal of Autism and Developmental Disorders, 43-6 (June 2013)
[article]
Titre : Assessing Recollection and Familiarity in Low Functioning Autism Type de document : Texte imprimé et/ou numérique Auteurs : Susan NI CHUILEANN, Auteur ; Jean QUIGLEY, Auteur Article en page(s) : p.1406-1422 Langues : Anglais (eng) Mots-clés : Recollection Familiarity High functioning autism Low functioning autism Index. décimale : PER Périodiques Résumé : Methods to assess recollection and familiarity separately in autism spectrum disorder were recently developed and piloted (Bigham et al. in J Autism Dev Disord 40:878–889, 2010). The preliminary data obtained via these methods showed that whereas recollection was mildly impaired in high functioning autism, familiarity was spared. The current study set out to replicate the methods of assessment for recollection and familiarity devised by Bigham and her colleagues with individuals diagnosed with low functioning autism (LFA). Three critical modifications to the original paradigms were made within the current study. The modifications and implications of the findings for individuals with LFA will be discussed.

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.

Titre : Declarative Memory and Structural Language Impairment in Autistic Children and Adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Sophie ANNS, Auteur ; Sebastian B GAIGG, Auteur ; James A. HAMPTON, Auteur ; Dermot M. BOWLER, Auteur ; Jill BOUCHER, Auteur Article en page(s) : p.1947-1958 Langues : Anglais (eng) Mots-clés : autism spectrum disorder familiarity language impairment memory recollection Index. décimale : PER Périodiques Résumé : Two experiments tested the hypothesis that a plausible contributory factor of structural language impairment in Autism Spectrum Disorder (ASD) is impaired declarative memory. We hypothesized that familiarity and recollection (subserving semantic and episodic memory, respectively) are both impaired in autistic individuals with clinically significant language impairment and learning disability (ASD(LI/LD) ); whereas recollection is selectively impaired in autistic individuals with typical language (ASD(TL) ). Teenagers with ASD(LI/LD) (n = 19) and primary school age children with ASD(TL) (n = 26) were compared with teenagers with learning disability (LD) (n = 26) without autism, and primary school aged typically developing (TD) children (n = 32). Both experiments provided strong support for the hypothesized links between declarative memory processes and lexical-semantic facets of language in the two autistic groups, but not in the TD group. Additional findings of interest were that declarative memory processes and lexical-semantic knowledge were also linked in the LD group and that the ASD groups-and to a lesser extent the LD group-may have compensated for declarative memory impairments using spared visual-perceptual abilities, a finding with potential educational implications. Relative difficulties with familiarity and recollection in ASD(LI/LD) and LD may help explain structural language impairment, as investigated here, but also the broader learning disabilities found in these populations.

LAY SUMMARY: Language impairment and learning disability affect 45% of the autistic population yet the factors that may be contributing to them is remarkably under-researched. To date there are no explanations of the lexical semantic (word meaning) abnormalities observed in ASD. We found that declarative memory is associated with lexical semantic knowledge in autism and learning disability but not in typical development. Difficulties with declarative memory may also be compensated for using visual-perceptual abilities by autistic and learning-disabled adolescents, which has positive implications for educationalists.

However, the involvement of successive memory processes in the profile of episodic memory in ASD needs more study. Here, we used event-related potentials (ERP) to investigate the time course of episodic recollection with an associative recognition paradigm with picture pairs. Twenty-two participants with ASD and 32 with typical development (TD), all right-handed, were included. Behavioral results confirmed difficulties in correctly recognizing identical pairs in the ASD relative to TD group. We found an unexpected amplitude decrement on the P2 (220-270?msec) and FN400 (350-470?msec) potentials, suggesting diminished priming and familiarity effects in the ASD relative to TD group. However, ERP data revealed that the recognition of associative information relies on the same electrophysiological process (old/new effect in the 600-700-msec late positive component) in ASD participants as in TD ones, with a parietal extension in the ASD group. These results suggest that the electrophysiological processes of associative recognition are qualitatively similar in individuals with and without ASD but may differ quantitatively. This difference may be driven by the reduced early processing of picture pairs that may in turn lead to their diminished integration into the semantic memory system, being partially compensated by a greater involvement of associative memory during the recollection process. Other studies would be useful to go further in identifying these cognitive processes involved in atypical recognition in ASD and their neural substrates. Autism Res 2020, 13: 1998-2016. © 2020 International Society for Autism Research and Wiley Periodicals LLC LAY SUMMARY: We identified diminished performance on the associative recognition of picture pairs in adolescents and young adults with autism when compared to typical development. Electrophysiological data revealed qualitative similarities but quantitative differences between-group, with diminished priming and familiarity processes partially compensated by an enhanced parietal recollection process.

To explore that, we used a Deese-Roediger–McDermott (DRM) false-memory paradigm, known to rely on associative relations between words. We therefore expected people with ASD in our study to be less susceptible to produce false memories. The novelty of this study was to use the externalized free-recall procedure to further explore the dynamics of correct and error responses in ASD. Method Adults with ASD and age- and IQ-matched adults in a comparison group were tested on a DRM task where 12 lists of strongly associated words were presented auditorily. At test, an externalized free-recall procedure was used, requesting participants to report presented words, and also any extra words that came to their mind (generated words). Results As expected, the clinical group produced fewer false memories than the comparison group, potentially due to abnormal relational processing. Moreover, unlike comparison participants, individuals with ASD tended to accept the critical words as belonging to the list rather than as generated, which demonstrates abnormalities in the monitoring capacity underlying an identify-to-reject process. Furthermore, analysis of questionnaires revealed that adults with ASD are less likely than typical adults to use memory strategies at both encoding and retrieval. Conclusions These findings are discussed in relation to the operation of error-inflating and error-editing mechanisms, both of which seem to be compromised in autism.
