Purpose: Bullying at school is one of the problematic 
behaviors of adolescents, which has recently attracted the 
attention of researchers and experts in the field of 
psychology in the last three decades, and has been the focus 
of many studies. Therefore, the purpose of the current 
research was to design a model of bullying tendency based 
on neurological function with the mediation of ataxia in 
students.
Materials and methods: The method of the current 
research is correlational and structural equation modeling 
(SEM). The statistical population of the research was made 
up of all 560 male students of the first secondary school in 
the ninth grade in 28 non-profit schools in District 5 of 
Tehran in the academic year of 2019-2019. 240 people were 
selected as the sample size by two-stage cluster method. The 
tools of data collection were the Illinois Bullying 
Questionnaire, the Rescue Neurological Function 
Questionnaire and the Toronto Dyslexia Questionnaire. In 
this research, SPSS22 and Amose 23 software were used to 
analyze the information obtained from structural regression 
equation modeling.
Findings: The results of the research showed that the path 
coefficient of neurocognitive function (β = -0.41, p = 0.001) 
and ataxia (β = 0.45, p = 0.001) is significant to bullying 
tendency.
Conclusion: According to the results, the indirect 
relationship between neurological function and the 
tendency to bully through aphasia is significant with β=-
0.35 at the significance level of p≤0.01.
