While different strategies have been described in the general population, no study has examined how these strategies relate to performance in autistic individuals, even though the task is widely used to characterize their visuospatial profile. To address this gap, the present study examined not only overall scores but also the underlying strategies used by autistic (ASD) and neurotypical (TD) adults during the BDT. Forty-one participants (ASD?=?18; TD?=?23) completed the standard BDT while eye-tracking and behavioral data captured both visual exploration and construction strategies. Globally, structured strategies?both in visual exploration and construction?were found to be the most effective, as they were associated with higher success rates and faster completion times, consistent with previous findings. At the group level, our results revealed that autistic participants employed these analytic strategies more frequently than neurotypical individuals, along with a stronger alignment between visual and construction approaches. The consistent use of these strategies in the autistic group may help explain the enhanced visuospatial performance observed in our study after controlling for manual dexterity and reported in earlier studies. These findings emphasize the importance of looking beyond traditional performance measures such as accuracy and completion time, highlighting that cognitive strategies are key to understanding visuospatial reasoning.

Visual strategies in solving Raven’s Matrices: Insights from autism / Alizée DIU in Research in Autism, 128 (October 2025)  

Public ISBD [article]  inResearch in Autism > 128 (October 2025) . - p.202694 Titre : Visual strategies in solving Raven’s Matrices: Insights from autism Type de document : texte imprimé Auteurs : Alizée DIU, Auteur ; Magali BATTY, Auteur ; Lucie BOUVET, Auteur Article en page(s) : p.202694 Langues : Anglais (eng) Mots-clés : Autism  Solving strategy  Raven’s Progressive Matrices  Eye-tracking Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorder (ASD) has been associated with superior performance on Raven’s Progressive Matrices (RPM), yet the mechanisms underlying this advantage remain unclear. In typically developing (TD) individuals, two main solving strategies have been described for RPM: Constructive Matching (CM) and Elimination Response (ER). This study aimed to investigate group differences in the use of these strategies through eye-tracking glasses, allowing an ecological completion. Forty-six adults (19 ASD, 27 TD) completed the standard RPM while wearing the mobile eye-tracking device. A composite score reflecting strategic tendency was calculated based on the percentage of matrix and response areas exploration and the number of transitions between them. Results revealed no significant group differences in accuracy or resolution time. Higher composite scores—indicating greater use of the CM strategy—were strongly associated with better performance across participants, as reported previously. Moreover, for successful items, autistic individuals showed a more pronounced preference for the CM strategy than TD individuals but both groups modulated their strategy according to item difficulty in a similar manner. These findings suggest that autistic individuals tend to engage in more analytical and constructive visual reasoning, possibly supported by cognitive traits associated with autism. As no performance advantage emerges with the moderately difficult RPM used here, we discuss the possibility that task complexity and adaptability to complexity may be key to revealing group differences. Future research using more complex tasks and diverse samples may clarify how autistic cognitive profiles affect reasoning strategies and RPM performance.
