Visual memory profile in children with high functioning autism.

Visual memory in children with high-functioning autism (HFA) is an area of debate. According to the few studies that have examined visual memory in children with autism, the memory profile appears to vary according to the memory process and type of stimuli, and contrasting results may be found. This study aims to analyze the visual memory profile of children with HFA. Fifteen children with HFA (mean age 9.6) and 15 typically developing children (TD; mean age 9.2) matched by chronological age and Leiter-R Brief IQ score took part in the study. Associative and recognition memory as well as visuospatial working memory were assessed. Impairments in face recognition and forward memory were found, whereas associative memory and shape recognition were preserved. The memory profile in children with Autism Spectrum Disorder (ASD) showed relatively stronger abilities in associative memory than in the other visual memory domains. The results support the hypothesis that the level of stimulus processing may influence memory performance by having a large impact on tasks and stimuli that require access to a semantic or global level of processing. In contrast to the TD population, children with ASD may have difficulty extracting underlying regularities from experiences and generalizing that information. Highlights Children with high-functioning autism (HFA) show preserved ability in associative memory and shape recognition. Face recognition appears to be a specific deficit in children with HFA. Associative memory appeared to be the strongest ability in the memory profile of children with autism spectrum disorder (ASD) and typically developing (TD) children.
