Prototypical category learning in high-functioning autism / Tony VLADUSICH in Autism Research, 3-5 (October 2010)
[article]
Titre : Prototypical category learning in high-functioning autism Type de document : Texte imprimé et/ou numérique Auteurs : Tony VLADUSICH, Auteur ; Olufemi OLU-LAFE, Auteur ; Dae-Shik KIM, Auteur ; Helen TAGER-FLUSBERG, Auteur ; Stephen GROSSBERG, Auteur Année de publication : 2010 Article en page(s) : p.226-236 Langues : Anglais (eng) Mots-clés : autism category learning prototype exemplar memory attention vigilance adaptive resonance theory Index. décimale : PER Périodiques Résumé : An ongoing debate in developmental cognitive neuroscience is whether individuals with autism are able to learn prototypical category representations from multiple exemplars. Prototype learning and memory were examined in a group of high-functioning autistic boys and young men, using a classic paradigm in which participants learned to classify novel dot patterns into one of two categories. Participants were trained on distorted versions of category prototypes until they reached a criterion level of performance. During transfer testing, participants were shown the training items together with three novel stimulus sets manifesting variable levels of physical distortion (low, medium, or high distortion) relative to the unseen prototypes. Two experiments were conducted, differing only in the manner in which the physical distortions were defined. In the first experiment, a subset of autistic individuals learned categories more slowly than controls, accompanied by an overall diminution in transfer-testing performance. The autism group did, however, manifest a typical pattern of performance across the testing conditions, relative to controls. In the second experiment, group means did not differ statistically in either the training or testing phases. Taken together, these data indicate that high-functioning autistic individuals do not manifest gross deficits in prototypical category learning. A theoretical discussion is given in terms of how perceptual grouping may interact with category learning.
