Comparison of Cognitive Inhibition in three Groups of Students With high, Normal and Low Mathematical Achievement

The purpose of the present study was to compare cognitive inhibition in three groups of students with high, normal and low achievement in mathematical.
This study was a causal-comparative study. The population of this study included all fifth grade students in 1393-94 in Arak. 33 students with high mathematical achievement, 39 students with normal mathematical achievement and 36 students with low mathematical achievement were selected by convenience sampling method. To collect the data, Raven’s IQ test, Conners Teacher Rate Scale, researcher constructed mathematical test and numerical stroop test were used. For analyzing the data, multivariate analysis of variance and follow-up Scheffe tests were used.
The results of multivariate analysis showed that there was a significant difference between performance of three groups of students in numerical stroop. Results of follow-up Scheffe test showed the interference score of numerical stroop effect and physical stroop effect in students with normal mathematical achievement was higher than students with high mathematical achievement and the interference score in students with low mathematical achievement was higher than other groups.
It can be concluded that students with low mathematical achievement have the lowest performance in cognitive inhibition.
