Standardization of children's visual search test

Visual search is an active search in the visual environment to find a particular object or feature among other specific objects or attributes. The purpose of this research was to standardize and evaluate the validity and reliability of the visual search test on first and second grade elementary schools students in Ahwaz.

The present research is descriptive through using exploratory factor analysis and principal component analysis. The research sample consisted of 264 children in District 4 of Ahwaz who were selected by random sampling and Participated in the visual search test. To determine reliability, a test-retest administration with a two-week interval was used. Moreover, the embedded image test was performed on 50 previous subjects to obtain the simultaneous validity of the test. The obtained data were analyzed using statistical methods of correlation, Cronbach's alpha, and factor analysis by SPSS 21 software.

The results showed the reliability coefficient of retest visual search test were in the range of 0.357 to 0.732 and Cronbach's alpha coefficient for visual search test was 0.827. Pearson correlation coefficient between the total positive index of the total visual search test and the latent shapes test was 0.642, which was significant with 99% confidence.

the research results showed the optimal psychometric properties of the visual search test. Therefore, this test can be used for research and clinical purposes.
