ORSATI, Fernanda T. et al. New possibilities on neuropsychological assessment in pervasive developmental disorders: Analyses of eye movements. Aval. psicol. [online]. 2008, vol.7, n.3, pp. 281-290. ISSN 1677-0471.

The objective of the present study is to use eye tracking in neuropsychological assessment of PDD children and adolescents. Ten clinically diagnosed PDD children and adolescents, mean age 11,9 (SD=3,22), were assessed. All children were pared by age and gender with a control group. The WISC III was used to assess intelligence and the eye movements parameters were assessed with Predictive Saccade Task (SP) and Anti-Saccade Task (AS). Significant differences between groups were found in the eye tracking tasks accuracy, errors and latency in the SP Task; and errors followed by correct responses in the AS Task. Results show lack on voluntary attention regulation, response inhibition, planning, and response initiation on the PDD group. All the differences corroborate previous literature. In conclusion, the assessment of eye movements in PDD children contributes to neuropsychological assessment, as well as to development of efficient interventions.
