Speed-precision assessment in difficulty level function in Asperger’s disorder
Main Article Content
Abstract
Introduction: Asperger’s Disorder (AD) is one of the neurodevelopmental disorders characterized by social impairments, difficulty in communication and restricted and repetitive patterns of behavior. Objective: To compare the motor performance in performing computational tasks with base on the relation speed and accuracy among people with typical development and AD, through the time of movement. Methods: The study included eight boys diagnosed with AD and eight children with typical development, matched for age and sex, to compose the control group. The task used to assesses the relative movement speed and accuracy, consisting in making hand movements directed at a target in three levels of difficulty (DI). Movement time was obtained by dividing the seconds to preestablished between the task (10) and the number of rings made on the target. ANOVA for repeated measures was used to compare the DI and between groups. Results: We observed that the movement time increased with the progress of DI. Conclusion: Individuals with AD had a significantly increased movement time compared to the control group in all DI. It is assumed that the difficulties are inherent in motor pathology and conditions of the patients with MT limit performance during task.
