AbstractResearch on memory in autism spectrum disorder (ASD) finds increased difficulty encoding contextual associations in episodic memory and suggests executive dysfunction (e.g., selective attention, cognitive flexibility) and deficient metacognitive monitoring as potential contributing factors. Findings from our lab suggest that age-related impairments in selective attention contribute to those in context memory accuracy and older adults tended to show dependence in context memory accuracy between relevant and irrelevant context details (i.e., hyper-binding). Using an aging framework, we tested the effects of selective attention on context memory in a sample of 23 adults with ASD and 23 typically developed adults. Participants studied grayscale objects flanked by two types of contexts (color, scene) on opposing sides and were told to attend to only one object-context relationship, ignoring the other context. At test, participants made object and context recognition decisions and judgment of confidence decisions allowing for an evaluation of context memory performance, hyper-binding, and metacognitive performance for context judgments in a single task. Results showed that adults with ASD performed similarly to typically developed adults on all measures. These findings suggest that context memory performance is not always disrupted in adults with ASD, even when demands on selective attention are high. We discuss the need for continued research to evaluate episodic memory in a wider variety of adults with ASD.

ABSTRACTThere's some controversy about memory disorders in teenagers with High-Functioning Autism Spectrum Disorder. Some researches maintain that the semantic memory remains intact while the episodic memory is the most affected system in comparison with Normal Development teenagers; however there are no researches connecting both kinds of memory in a single analysis. The purpose of this study was to evaluate if the episodic recognition improved when semantic keys where autogenerated in the coding phase in these teenagers. The results produced shown that there aren't statistically significant differences between the category's autogeneration compared to the absence of category's autogeneration in the episodic recall.RESUMENExiste controversia acerca de las alteraciones del funcionamiento de la memoria en adolescentes con trastorno del espectro del autismo de alto funcionamiento. Algunas investigaciones sostienen que la memoria semántica está intacta mientras que la memoria episódica es el sistema más afectado en comparación con adolescentes con desarrollo normal; sin embargo no hay estudios que relacionen ambos tipos de memoria en un solo análisis. El  objetivo de este estudio fue evaluar si el reconocimiento episódico mejoraba al autogenerar claves semánticas en la fase de codificación en estos adolescentes. Los resultados mostraron que no hay diferencias estadísticamente significativas entre la autogeneración de la categoría en comparación con la ausencia de la autogeneración de la categoría en el recuerdo episódico.
