Abstract

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'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
