Aims: Different aspect of visual information project to visual system via different frequencies. The image details project by means of high frequency and the generalities project via low frequency. The purpose of present study was to investigate the difference between attention to the filtered and non-filtered images of information in the elementary and junior high school students.

Methods: This cross-sectional comparative study was done on 2 regions of Tehran elementary and guidance school students in 2012. Subjects were selected using non probably sampling method and 132 students from 3 elementary and guidance schools were participated in the study totally. Data were collected using the modified visual dot-probe test. Data were entered to SPSS and due to have one group and three different frequency filters, repeated measurements statistical evaluation was used.

Findings: The right answers mean in consistent display mode at low frequency was (18.96±2.10) and at the inconsistent mode without the filter was (14.04±1.81). Subjects' mean reaction time was more in the consistent display at high frequency (0.65±0.36) and in the inconsistent mode without the filter (0.59±0.33). There was a significant difference between subjects' right answers and reaction time to different presented stimuli in respect to the consistent or inconsistent display.

Conclusion: Low frequency filtered images are processed more accurate and rapid compared to the high frequency filter images and without filter is in normal children and adolescence and the tendency to use the low frequency filter is more than are high frequency.
