The purpose of this study was to compare the red and blue colors in elementary student’s brain frequencies. The study was causal-comparative. The statistical population of the present study was all elementary students of Tabriz District 4 in the academic year of 2019-20. At first, using announce recall, each person’s health was confirmed physically and mentally. Then, 30 of them were selected by simple random sampling. Each subject was shown red and blue on the computer monitor for 15 minutes and at the same time a small amount of electroencephalography has been recorded in the delta, theta, alpha and beta frequency bands. Then, data were then analyzed by multivariate analysis of variance and all stages were calculated by SPSS software version 21. The results showed that red stimulus increased beta brain frequency at FP1 and blue stimulus increased alpha brain frequency P <0.1. Based on the findings of the present study, it is concluded that the use of red in the educational environment of schools can have a beneficial effect on students.

Aim: The aim of this study was to evaluate the effectiveness of neurofeedback-based virtual scenarios in form of a computer game in healthy individuals. Method: The design of this study was experimental and the statistical population was all male students of Tabriz Islamic Art University in 2019. The sampling estimation was based on Cohen's table and a sample of 24 volunteers was included in the study. To collect data they were tested in three groups include positive(reward), negative(punishment) and Competitive(effect on the opponent) reinforcement. The attention level of each player and his\her performance are collected through electroencephalogram(EEG) and recorded by the multithread structure of the game. In designed scenarios, the threshold of each individual's concentration is used to regulating the flow of the gameplay, thus the attention training process is adjusted to the same person's brain activity. In order to test the hypotheses of this research, a user study has been conducted; The results were analyzed by repeated measures ANOVA using SPSS 21 software. Findings: The results showed that competitive reinforcement, negative reinforcement and positive reinforcement are effective in increasing attention level. Also, analyzing the data from the user experience questionnaire showed that designed scenarios are capable to immerse players in the gameplay and engage them with the training flow. Conclusion: using BCI based game and neurofeedback result in increasing the efficiency of attention training.

Introduction: The aim of this study was to investigate the effect of role and field effect on product perception. Method: This study was a causal-comparative study. The statistical population of this study was all male students of Islamic Art University of Tabriz in the year 2018. At first, randomly, 30 people were selected from those who were eligible for testing, then a video clip was presented in two stages (once the rules of the law were applied in the articles of the law and once the rule of law was not observed) At the same time, quantitative electroencephalography was recorded in the delta, theta, alpha and beta frequency bands. The data were analyzed by multivariate analysis of variance and all stages were calculated using SPSS version 23 software. Results: The findings showed that there was a significant difference in beta frequency in two stages of video clip presentation (P 0.05) . Conclusion: Based on the findings of this research, it can be said that the products that the gistalt's role and law are observed in are more likely to attract the attention of the user.

Aim: Problems reading one of the most fundamental problems faced by children with learning disabilities. This study also aims effectiveness of neuropsychological rehabilitation for people with dyslexia disabilities was sustained attention. Methods: This study is a quasi-experimental design with the two groups. That a group of 10 people, including people with dyslexia disabilities and 10 in the control group was also included. This means that people with a learning disability but did not intervene for them. Instruments included neuropsychological rehabilitation program and the Continuous Performance Test. Data analysis using SPSS version 19, using multivariate analysis of covariance was performed. Findings: Data analysis showed that, between mean scores of pre-test and post-test experimental and control groups there was a significant difference (P

Introduction: The present study was conducted to evaluate the effect of brand advertising on the brain wave pattern of interested and unproductive consumers of Nike brand. Method: This study was a causal-comparative study. The statistical population of the present study was male students of Tabriz University in the period of 2016-17. At first, using brand-name questionnaire and researcher-made questionnaire, brand-related students were identified as interested and uninvited students, and were randomly selected from 20 individuals and 20 uninitiated. Then the video clip that was used for Nor Marketing has been broadcast and at the same time a small amount of electroencephalography has been recorded in the delta, theta, alpha and beta frequency bands. Data were then analyzed by multivariate analysis of variance and all stages were calculated by SPSS software version 19. Findings: The results of the research showed that there is a significant difference between those who are interested and not interested in advertising brand. There was a significant difference between the two groups in the delta, theta, and alpha frequencies (P 0.05). Conclusion: Based on the findings of this research, it can be said that understanding the early functions of the human brain in the study of consumer purchasing behavior is possible using electrophysiological devices.
