This study explored how memory for actions in children with autism spectrum disorder (ASD) and typically developing children might benefit from self-performance and experimenter demonstration, and whether these groups possess metamemory knowledge of their performance levels in this task. Children with autism were less accurate on the action memory task when they carried out each action themselves during encoding, or when no actions were implemented during this phase, but this difference was abolished when the experimenter demonstrated each action during encoding. Despite clear difficulties in the self-performed condition relative to typical children, the group with ASD also showed a beneficial effect of performing the actions themselves during instruction. Finally, children with autism were as accurate as typical children in judging the accuracy of their own memory performance, indicating an absence of metamemory difficulties for this task.

The present study examined the recognition of numerical stimuli briefly presented in the peripheral and the central (foveal) visual fields of children with autism. The participants were 5 children with high-functioning Autism Spectrum Disorder (ASD) and 10 typically developing (TD) children of similar chronological age. The stimuli were number strings presented on a personal computer screen for 160 msec in the position of the fixation point (foveal condition) or in the peripheral visual field (retinal eccentricity of 16 degrees) in one of the eight radial positions selected randomly (peripheral condition). The participants’ task was to report the number of stimuli. The results showed that there were no significant differences in the mean response times between the TD and ASD groups. However, the mean percentage of correct answers in the ASD group was significantly higher than in the TD group for the peripheral condition. These results suggest that the effective visual field of the ASD group is expanded compared with the TD group. We discussed the relationships between perceptual characteristics and cognitive processes particular to ASD children.

Background Autism is a global disorder, but relatively little is known about its presentation and occurrence in many developing countries, including Libya. Aims Methods Prospective hospital-based study of all children referred to a neurodevelopment clinic between 2005 and 2009 with the diagnosis of either speech and language difficulties or behavioral difficulties. Results A total of 38,508 children were seen in the pediatric outpatient clinics of KH, Tripoli, between 2005 and 2009. Of these, 180 children were referred to the neurodevelopment clinic with history of delayed speech and language and or behavioral difficulties. A diagnosis of autism was made in 128 children, which gives a prevalence of approximately 1 in 300. Conclusion The prevalence of autism in Libya is probably similar to that seen in the USA and the UK. No data were available for comparison from either Arab or other developing countries. Autism is an important differential diagnosis of any language disorder ‘and behavioral difficulties’.
