Intact fluency in autism? A comprehensive approach of verbal fluency task including word imageability and concreteness / Odett TÓTH in Autism Research, 15-4 (April 2022)  

Public ISBD [article]  inAutism Research > 15-4 (April 2022) . - p.677-686 Titre : Intact fluency in autism? A comprehensive approach of verbal fluency task including word imageability and concreteness Type de document : texte imprimé Auteurs : Odett TÓTH, Auteur ; Orsolya PESTHY, Auteur ; Kinga FARKAS, Auteur ; Anna GUTTENGÉBER, Auteur ; Eszter KOMORÓCZY, Auteur ; János M. RETHELYI, Auteur ; Bálint SZUROMI, Auteur ; DezsÅ‘ NEMETH, Auteur Article en page(s) : p.677-686 Langues : Anglais (eng) Mots-clés : Adult  Autism Spectrum Disorder  Autistic Disorder  Humans  Neuropsychological Tests  Phonetics  Semantics  Verbal Behavior/physiology  cognitive  concreteness  imageability  verbal fluency Index. décimale : PER Périodiques Résumé : Verbal fluency is a cognitive function reflecting executive functions and the ability to retrieve the appropriate information from memory quickly. Previous studies reported conflicting results-impaired and intact verbal fluency-in autism spectrum disorder (ASD). Most studies concentrate on overall word productivity, errors, perseverations, clustering, or switching. We used a comprehensive approach to evaluate the reported discrepancy in the literature and introduced a new angle using the concept of word abstraction and imageability. Moreover, we analyzed the performance in two-time intervals (0-30 s and 31-60 s) to assess the temporal dynamics of verbal fluency and a possible activation or initiation deficit in autism. Sixteen adults with ASD and 16 neurotypical control participants, matched by gender, age, and education level, participated in our study. Contrary to our expectations, we did not find a significant difference between groups in word productivity, the number of errors, clustering, or temporal dynamics, neither in semantic nor in phonemic fluency tasks. Surprisingly, the two study groups' performance did not differ in terms of imageability or concreteness characteristics either. Our results raise the possibility that verbal fluency performance is intact in autism. We also suggest using a comprehensive approach when measuring fluency in autism. LAY SUMMARY: People with autism tend to think and communicate differently. In our study, we tested whether people with autism come up with more concrete or imageable words and whether their performance is better compared with neurotypicals in the beginning or in the later phase of a task measuring how many words they can produce in a minute. We did not detect any difference between the two groups; however, we recommend studying verbal fluency in autism from more and different angles in the future.

Qualitative analyses of verbal fluency in adolescents and young adults with high-functioning autism spectrum disorder / Eiko INOKUCHI in Research in Autism Spectrum Disorders, 7-11 (November 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-11 (November 2013) . - p.1403-1410 Titre : Qualitative analyses of verbal fluency in adolescents and young adults with high-functioning autism spectrum disorder Type de document : texte imprimé Auteurs : Eiko INOKUCHI, Auteur ; Yoko KAMIO, Auteur Article en page(s) : p.1403-1410 Langues : Anglais (eng) Mots-clés : High-functioning autism spectrum disorders  Verbal fluency  Action fluency  Semantic strategy  Cognitive flexibility  Generativity Index. décimale : PER Périodiques Résumé : Abstract Systematic qualitative analyses of verbal fluency might aid our understanding of the characteristic cognitive processes in individuals with autism spectrum disorder (ASD). In this study, we compared through qualitative and quantitative analyses performance on letter fluency (LF), category fluency (CF), and action fluency (AF) in adolescents and young adults with high-functioning autism spectrum disorders (HFASD) with that of an age-, gender-, and IQ-matched control group. Quantitative analyses revealed significantly fewer correct responses on category and action fluency and significantly more intrusions on category fluency in individuals with HFASD than in control participants. Qualitative analyses revealed significantly fewer semantic clusters and significantly more phonemic clusters during action fluency in individuals with HFASD compared to control participants. With respect to action fluency, the number of correct responses and clusters were related to verbal IQ for individuals with HFASD but not for control participants. We discuss these results in terms of abnormalities in semantic/phonemic strategy choice, cognitive flexibility, and generativity in ASD.

Small Semantic Networks in Individuals with Autism Spectrum Disorder Without Intellectual Impairment: A Verbal Fluency Approach / Felicitas EHLEN in Journal of Autism and Developmental Disorders, 50-11 (November 2020)

The study explored differences in semantic network organisation of adults with ASD without intellectual impairment. We assessed clusters and switches in verbal fluency tasks ('animals', 'human feature', 'verbs', 'r-words') via curve fitting in combination with corpus-driven analysis of semantic relatedness and evaluated socio-emotional and motor action related content. Compared to participants without ASD (n = 39), participants with ASD (n = 32) tended to produce smaller clusters, longer switches, and fewer words in semantic conditions (no p values survived Bonferroni-correction), whereas relatedness and content were similar. In ASD, semantic networks underlying cluster formation appeared comparably small without affecting strength of associations or content.

Initial evidence for intact emotion fluency in autism vs. ADHD and community groups / Amy CAMODECA in Research in Autism, 123 (May 2025)  

Public ISBD [article]  inResearch in Autism > 123 (May 2025) . - 202565 Titre : Initial evidence for intact emotion fluency in autism vs. ADHD and community groups Type de document : texte imprimé Auteurs : Amy CAMODECA, Auteur Article en page(s) : 202565 Langues : Anglais (eng) Mots-clés : Autism  Emotion Word Fluency Test  Verbal Fluency  ADHD  Executive Function Index. décimale : PER Périodiques Résumé : Background The Emotion Word Fluency Test (EWFT) accounts for unique variance in Theory of Mind (ToM). As ToM weaknesses are observed in Autism Spectrum Disorder (ASD), it was hypothesized that an ASD group would demonstrate performance weakness on the EWFT. Method A community sample for EWFT comparison (COM, n = 113, X?age=10.43) was obtained from a University day camp and faculty/staff children. The clinical sample included 38 children with ASD (meanage=11.10) and 86 children with Attention-Deficit Hyperactivity Disorder (ADHD, meanage=9.89). EWFT and Animals was administered as part of a comprehensive evaluation. Results Analyses included EWFT-total and Animals-total (n-correct words in 60"), and the following EWFT scores: n-switches (changing between positive/negative emotions), n-clusters (groups of positive or negative emotions stated in order), and n-correct emotions in the first-15" and second-15" (automatically-accessed vs. strategically-accessed words, respectively). Controlling for age, no between-group differences mean differences were found for EWFT-total, n-switches, n-clusters, or second 15" interval.No within-subject differences between EWFT-total and Animals-total were observed. Autism Diagnostic Observation Schedule-2 scores were not significantly correlated with any EWFT/Animal scores. However, mediational analyses indicated that n-switches increased EWFT-total more efficiently for the COM vs. ASD/ADHD groups. Compared to the COM group, the ADHD group had a higher frequency of at least one EWFT set loss and generated fewer words in the first 15" interval of the EWFT. Conclusions This study provides initial evidence for intact emotion word fluency in ASD, and suggest switching is a differentially efficient emotion-word-generation strategy depending on group membership. This study provides a basis for additional research.

We applied different verbal fluency tasks designed to decrease or enhance this limitation. A group of high-functioning individuals with ASD and a group of typically developed individuals matched for -age, -IQ and -education, were tested in three verbal fluency tasks. In task 1, we replicated previous findings of an initiation impairment. In tasks 2 and 3, with simple manipulations, we observed that the differences between the groups were respectively eliminated or enhanced. We have not only provided further evidence of impairments in the initiation of a response, but we remarkably show how to circumvent them.
