There is no doubt that with the normalization of relations between Iran and Saudi Arabia after a long period of tension, one of the most key results of this agreement, that is, its impact on the security relations between Iran and the Arab world, and at the center of it, Iran and the Persian Gulf, is of particular importance. will be. Yemen, Lebanon, Syria and Iraq, during the past years, have always been the scene of indirect confrontation between these two regional powers. But the question is, what is the reason for these tensions? What effect has the agreement between Iran and Saudi Arabia had on the continuation of this cold war, and more importantly, what effect will this informal understanding have on the economic, political and security-military dimensions of Iran and other Persian Gulf countries? Some believe that the tensions between the two countries are caused by the endangerment of the oil-economic interests of these countries, some believe that this fear is caused by the possible increase of Iran's influence in the region, and in the opinion of others, the Arabs are worried about America's tendency towards Iran and perhaps attention less the United States to them. But perhaps these reactions can be explained in the form of defensive realism and according to "Taliaferro" one of its four main assumptions, i.e., the "security enigma", by means of which, every action of a government to increase its security, on the part of governments The competitor is considered as a hostile action. The following article tries to answer this question by assuming that the agreement between Iran and Saudi Arabia, as a factor that caused the security puzzle in the relations between the Arab world and Iran, both before and after it was achieved.

Objective: An important cognitive control process is the ability to inhibit, that mature at different rates during childhood to adolescence. The aim of our research was to construct and validate computer-based Stroop animal size test in children for measuring selective attention and response inhibition. Research Methodology: In this survey study, we prepared the test, after the approval of experts and software development, at first test-retest reliability with a two week was evaluated in a separate sample (N=50, 5-12 years old children), then data was collected from 92 children 5-12 years old (46 girls and 46 boys) included 22 children with attention deficit/hyperactivity disorder (ADHD) studied in the academic year 2022-2023 in Alborz province. Participants decided the real size of animals by pressing response keys on computer. ANOVA, Multivariate analysis, Pearson correlation coefficients and Cronbach α were used to assess reliability and validity (p<0.05). Findings: The findings showed test-retest reliability in significant range (p<0.01). The correlation was high for Stroopnum, (r=0.83), Inconsistent answers, (r=0.72), Wrong answers, (r=0.89) but lower for Consistent answers, (r=0.28) and Reaction time, (r=0.41). To assess the internal consistency, Cronbach Alpha 0.91 computed. ANOVA analysis for comparing children's function in different age groups was (p<0.000). Conclusion: Multivariate analysis was used in comparing children with ADHD to the control group, results showed significant difference between groups in Stroop components, (p<0.007). This computerized Stroop animal size test had satisfactory reliability and validity, that can measure cognitive functions such as selective attention and inhibition in children.
