| This research is executed to find a valid instrument for diagnosis of visual perception deficiencies. Test of visual perception is composed of 7 subskills as follows: visual-motor integration, figure ground, visual discrimination, form constancy, visualization, spatial relations, and visual sequential memory. The research covered 1600 elementary school and pre school students: 800 boys: 400 preschool students and 400 first grade elementary school students. 800 girls: 400 preschool students and 400 first grade elementary school students. The selection of the sample followed a multistage sampling method. A developmental test of visual perception and the Goodenough test were administered individually. Goodenough test was used to determine the value of criterion validity. Descriptive statistics, Cronbach__AWT_QUOTE__s alpha, Pearson correlation coefficient, and t–test were used to analyze the data. The results showed: 1- Norm Tables for the total scores were demonstrated and listed for gender and academic grade, separately. 2-The reliability coefficients of test were found to be .74. 3-The correlation coefficient between the created test and the criterion test for the total score and all subtests were significant. 4- The difference between the developmental visual perception in boys and girls was significant. 5- The difference between developmental visual perception in preschool and first grade elementary school students was significant. |
