The Effect of Computer-Based Intervention on Enhancing Visual Perception of Preschool Children with Autism: A Single-Subject Design Study

Abstract

The purpose of the study is to examine the effectiveness of a computer-based intervention program for enhancing visual perceptual skills of preschool children with autism. The participants were recruited from a convenience sample including two children diagnosed with autism spectrum disorders and between the age of 4 and 5 years. The study was undertaken in the participants' homes. The instruments used to collect data include computer software programs, non-standardized two-dimensional tests, and a standardized test: The Developmental Test of Visual Perception-2 (DTVP-2). A singlesubject ABAB design was used to measure changes in the participants' visual perceptual skills. The results suggest that computer-based intervention is effective in improving the motor-reduced visual-perceptual skills in preschool children with autism. Both participants demonstrated an increase in the motor-reduced visual-perception composite score of the DTVP-2. The results from this study can add to the growing body of evidence in regards to the effect of computer-based interventions on improving motor-reduced visual perceptual skills in children with autism.
