In neuroscience, decision-making is considered a sensory process that begins in the Brian cortex. When making decisions, sensory information must be interpreted and translated into behavior. In this regard, this study has attempted to investigate the effects of a new branch of neuroscience (Neuroaccounting) on financial and budget decisions. The present study is practical in nature and is considered as a descriptive-exploratory correlation study. The required data were collected through the distribution of questionnaires among 245 individual investors. Data analysis has been done using structural equation modeling. This study includes two independent variables, stimuli-relay (SR) and intuition. The dependent variables of this study are: (1) dynamic cognitive processing (DCP) with four subconstructs: multi-dimensional perceptual space (MDPS), behavioral outcome space (BOS), resolution and optimization. (2) Expertise includes two subconstructs: memory and resolution-Ex. According to the research findings, the variables of SR and intuition have positive and significant effects on the variables of DCP and expertise. Also, the research findings show that two independent variables have a positive and significant effect on the six sub-constructs of the study. Finally, when making financial and budget decisions, managers should consider internal and external information as well as the consequences of choosing a specific decision.

Introduction: The aim of this study was to evaluate the effectiveness of behavioral self-regulation on working memory, attention deficit and hyperactivity in children. Method: This research was performed experimentally with a pretest-posttest design with an experimental group and a control group. The statistical population included all children aged 7 to 12 years with attention deficit hyperactivity disorder who referred to counseling and psychology centers in Tehran's District 5 in the academic year 2019-2020, and were treated with Ritalin. Sampling was done by simple random method. Then, among the 40 people who received the most symptoms of attention deficit hyperactivity disorder and the lowest score in working memory, they were randomly divided into experimental and control groups. The experimental group separately participated in 8 weekly sessions of 60 minutes of research intervention and the control group remained on the waiting list. The research instruments included the Pediatric Symptoms Questionnaire (CSI-4) and the Work Memory Scale of Aloy et al. (2008). Statistical data were analyzed using multivariate analysis of covariance. Results: The findings indicate that self-regulatory behavioral interventions are effective on working memory and reducing the symptoms of attention deficit hyperactivity disorder in children. Conclusion: Behavioral self-regulation skills training had a significant effect on working memory of ADHD children.

Aim: Neuropathic pains are common complications of chronic diabetes that have a negative effect on patients' mood. The present study, however, was conducted with the aim of determining the pure and combined effect of M1 and F3 anodic tDCS on reducing psychological distress in type 2 diabetes patients with neuropathic pain. Method: The study is a four-group double-blind randomized clinical trial. The statistical population of the study was all patients aged 45 to 65 years with type 2 diabetes who were members of the Bonab Diabetes Association in the winter of 2021 and spring of 2022, identified by specialists as having neuropathic pain. The research sample was 48 people selected in a purposeful way and according to the inclusion and exclusion criteria. Then, the subjects were randomly assigned to 4 groups. Patients in 4 groups received their own interventions for 12 sessions, three times a week. The data collection tool was the 42-item depression, anxiety, and stress scale (DASS). Results: According to the results, the average psychological distress in the post-test, 1-month follow-up, and 3-month follow-up phases, compared to the pre-test phase, was significantly reduced. However, there was no difference in the mean psychological distress scores between the other phases (post-test, 1-month follow-up, 3-month follow-up). That is, even up to the 3-month follow-up phase, the effect of the interventions remained. Conclusion: Therefore, the application of transcranial direct current stimulation, considering its therapeutic potential, can be expanded in people with diabetes.

Aim: The purpose of this study was to determine the effects of audio-visual modeling on mu rhythm suppression in basketball lay-up shot. Method: For this purpose, 13 physical education students of Shahid Rajaee Teacher Training University participated voluntarily in this study. Order of presenting visual and auditory stimuli was counter-balanced among participants. Participants were randomly divided into two groups: the first group, observed the visual stimulus model first, then received the auditory stimulus, and the second group received the visual stimulus after the auditory stimulus and eventually presented the audio-visual stimuli. Brain waves were recorded by EEG in three conditions, presenting visual and auditory and audio-visual stimuli and were transformed to quantitative data by Neuro-guide Software. Results: Results of two-way repeated measures ANOVA in a 3 (condition) × 3(brain area) design revealed that main effect of the brain area was significant, results of Bonferroni post hoc test for brain area main effect showed that the mu rhythm was significantly more suppressed in Cz compared to C3 brain area (P=0.014). In addition, the results also showed that the mu rhythm in CZ was significantly more suppressed than C3 in both visual (P=0.025) and audio-visual (P=0.014) stimuli conditions, however, there were no significant differences between the mu rhythm Suppression in auditory condition among three brain areas. Conclusion: Finally, results confirmed that the integrity of the audio-visual stimuli causes further in mu rhythm suppression and mirror neurons activation.

The current study was conducted with the aim of determining the effectiveness of neurofeedback-based training within the aggression and emotional dysregulation of soccer players. The research method was a quasi-experimental type and a pre-test-post-test research design with a control group. The statistical population of this research was the football players of Astaneh Ashrafieh city in 1400, from this statistical population, 24 adolescent boys were chosen and after matching based on age and education level, they were randomly separated into 2groups of 12individuals of the experimental group and control group supplanted. then Maxwell and Morris2007 competitive aggression questionnaire(2007) and Gertz and Roemer's(2004) difficulty in emotion regulation questionnaire are administered as pre-test and post-test for both groups. The group receiving neurofeedback training was given the shortest training according to the treatment protocol of 15 sessions of 30 minutes. The results of the analysis showed that the difference between the adjusted difference between the neurofeedback training group and the control group within the post-test stage was significant within the components of anger(P<0.001) and aggression(P<0.001). The contrast between the adjusted difference of the training group for neurofeedback with prove in the post-test phase on the total score of emotional dysregulation was significant(P<0.001). This significant level was repeated in all components of emotional dysregulation except the absence of emotional feelings(P>0.155). Hence, it can be said that training on neurofeedback has reduced the competitive aggression and maladjustment of football athletes. In other words, rewarding the optimal brain makes individuals learn how to perform well.

Objective: The present study was conducted with the aim of Comparing the effectiveness of transcranial direct current stimulation and repeated Transcranial Magnetic Stimulation treatment on working memory, impulsivity and self-harm behaviors in people with borderline personality. Method: The current research is semi-experimental with pre-test-post-test and control groups. The statistical population of this research includes the clients of some counseling centers in Ardabil city in 1401. The sample of this study consisted of 45 people with borderline personality disorder who were selected by the available sampling method. This study included 3 groups and each group included 15 people. Each subject was randomly assigned to two treatment groups (tDCS and rTMS) and a control group. The tools of this research included N-back working memory test, Barratt Impulsivity questionnaire, self-harm questionnaire, tDCS and rTMS.Findings: The results showed that the treatment of tDCS and rTMS has a significant effect on impulsivity, working memory and self-harm in borderline personality disorder patients. And the results show that after controlling the effect of the pre-test on the post-test to compare scores, working memory, impulsivity and self-harm among the three groups, there is a significant difference at the error level (0.05). The results of Bonferroni's post hoc test also showed that between the effectiveness of the two treatment methods, rTMS treatment was more effective than tDCS. Conclusion: The results showed that tDCS and rTMS led to the improvement of working memory in people with borderline personality disorder and also reduced the level of impulsivity and self-harm behaviors.

Purpose: The present study was conducted with the aim of determining the effect of mindfulness intervention on perceived stress and salivary immunoglobulin A (sIgA) levels of elite wrestlers during the competition period. Methods: 20 male elite freestyle wrestlers (age: 22.36±2.38) participated in this study and were randomly assigned to experimental (mindfulness-based intervention) and control groups. Two official competitions were used as pre-test and post-test. Perceived stress was measured by the short version of Perceived stress scale. Awakening and competitive levels of salivary immunoglobulin A were evaluated using the ELISA method. The experimental group participated in 8-week mindfulness intervention (two sessions per week). Data were analyzed using repeated measures ANOVA and independent t-test. Results: The results showed that after the 8 weeks of intervention, perceived stress was reduced in the experimental group. Hoewer, the awakening and competitive levels of immunoglobulin A did not show a significant difference compared to the control group from pre-test to post-test. Conclusion: In general, it can be concluded that mindfulness intervention can be a strategy to reduce the perceived stress in elite wrestlers during the competition period. Future studies with larger samples with other disciplines can better demonstrate the comprehensiveness of the results.

Background: Executive functions in primary school children are very important because they can have a decisive role in improving children's performance in school and even for their future. Aims: The purpose of this study was to investigate the effect of computer games and motor games on the executive functions of primary school students. Methods: The current research was a semi-experimental. The statistical community was all the 7-9 years old primary school students of Babol city in 1401. To select the sample, three schools were selected through random sampling. 15 people from each school were randomly divided into three groups (movement games, computer games and control). The research tool was BRIEF Executive Functions Questionnaire. Movement and computer group programs were conducted for 12 sessions (4 weeks and three sessions per week). The control group continued their usual programs. Analysis of covariance test and Bonferroni's post hoc test were performed at the level of p<0.05. Results: The results of the analysis of covariance showed that by considering the pre-test scores as the control variable, the training interventions (computer games and movement games) caused a significant difference between the experimental groups. Based on the results of Bonferroni's post hoc test, the difference in executive function variables between the two experimental groups and the control group was significant (p<0.001) but non-significant with each other (p>0.05). Conclusion: motor and computer games can be used as a practical option in order to improve children's executive functions.

Objective: The present study was conducted with the aim of investigating the effectiveness of mindfulness training based on virtual reality on improving the cognitive regulation of emotions in students with specific learning disabilities. Method: The research was semi-experimental with a pre-test, post-test and a two-month follow-up design. The statistical population was female students with math learning disorders in Kermanshah learning disorder centers. A cognitive emotion regulation questionnaire was administered to students, and among those who met the criteria for entering the research, 24 students were selected by purposeful sampling and randomly placed in two groups of 12 people, experimental and control. The experimental group underwent 10 sessions of mindfulness training based on virtual reality, but the group did not receive the training certificate. One week after the last training session, a post-test was conducted and two months later, a follow-up test was conducted. Data were analyzed using repeated measures analysis of variance. The results showed that mindfulness training has improved students' cognitive emotion regulation (P<0.001) and these effects were stable in the follow-up phase. Since mindfulness training based on virtual reality improves the cognitive regulation of these students' emotions, this efficient method can be used to improve the cognitive regulation of these students.
