Evaluation of visual perception with the SKILLS Visual Perceptual Test (TVPS-3) in children aged 6 to 14 years with learning disorders

Abstract

INTRODUCTION: The visual perceptual skills provide the ability to organize, structure and interpret visual stimuli, giving meaning to what is seen. These are important attributes for all learning situations and contribute to academic performance. OBJECTIVES: To evaluate through TVPs-3 test visual perception of students aged 6 to 14 with learning disorders, with the specific objective to identify which visual perceptual skills will prove altered, and to classify the specific disorders through the signs and symptoms specific disorder and correlate changes in visual perceptual skills with the learning disorder. MATERIALS AND METHODS: Cross-sectional, descriptive study in 46 children with learning disorders. Students were evaluated with TVPs-3 test, and the results were presented in visual discrimination, visual memory, spatial relationship, constancy of form, sequential memory, figure-ground, visual closure and overall score. The variables were compared with the standard values described in the literature. It conducted the statistical significance test using the T-Student version, two-tailed. The probability of statistical error considered was equal to 5%.  RESULTS: The overall score percentile values presented below, or well below the average in 98% of the sample. The results of significance tests found for visual discrimination was 0.925, 0.959 visual memory, spatial relationship 0.880, constancy of shape 0.917, 0.698 sequential memory, figure-ground 0.834 and visual closure 0.888. CONCLUSIONS: The statistical results indicate a strong relationship between the very low values ??found in the performance of each skill of visual perception and learning disorder.
