Children with developmental coordination disorder (DCD) display slowness, inaccuracy, and insufficient coordination in the performance of motor skills. Compared to children with normal development, they generally have poorer performance in tasks that require visual-motor integration. We evaluated the effect of tDCS stimulation on visual-motor integration in children with DCD. In this quasi-experimental study, featuring a pre-test-post-test design, 40 students with DCD aged 7-10 years were selected according to the inclusion criteria and randomly assigned into two groups: tDCS stimulation and artificial stimulation. In the pre-test, participants took a visual-motor integration test. The intervention phase was administered for 5 consecutive days. Each day, the subjects underwent either electrical stimulation in the motor cortex (anode at C3 and cathode at Fp2) or artificial stimulation. The post-test was administered in the last session. Short-term and long-term follow-ups were performed 1 day and 42 days after the post-test, respectively. Repeated measures ANOVA was used to analyze the data. The results showed that electrical stimulation of the motor cortex significantly improves the visual-motor integration of children with DCD. The follow-up results supported the persistence of motor-visual integration in these children. In general, the results emphasized the effectiveness of tDCS exercises on motor-visual integration in children with DCD.

The aim of the research was to determine the difference in the effectiveness of cognitive therapy with positive psychotherapy on executive functions in patients with mild brain damage. Method The present research method was a semi-experimental type with a pre-test and post-test design with a follow-up period. The statistical population of this research included all people with mild brain damage who referred to Shahada Haftam Tir and Baqity Elah Hospitals in Tehran in 2019. Among them, 30 people were purposefully selected and randomly assigned to three groups of cognitive rehabilitation treatment, positive psychotherapy and control group. The Wisconsin test was performed on each of the groups. The first experimental group received cognitive rehabilitation therapy and the second experimental group received positive psychotherapy. People in the control group did not receive any intervention. Analysis of variance with repeated measurements was used to analyze the data. The results showed that both interventions have an effect on increasing executive functions. But the effectiveness of cognitive rehabilitation treatment is more on executive functions(P05/0<). Therefore, it is recommended to neurologists and psychotherapists in order to reduce the complications of brain damage, in addition to medical treatments, cognitive rehabilitation treatment should be used as a complementary method

The aim of this study was to determine the effectiveness of neurofeedback on continuous attention, working memory and visual - motor perception in primary school students with specific learning disorder.

The current study was an experimental type with a pre-test-post-test design with a control group. The statistical population of this research included all primary school students in Tabriz city, among them, 30 people diagnosed with learning disorders in Tabriz learning disorders centers were selected by purposive sampling method and using randomly were replaced into experimental and control groups (15 people in each group). In all two groups of N-back, continuous performance test and visual perception -motor Bender-Gestalt as pretest and post-test completion. Neurofeedback was performed in the experimental group for 20 sessions of 30-45 minutes (3 times a week for seven weeks) and the control group received no interventions. Data were analyzed by using multivariate covariance analysis in SPSS.20.

There is only a significant difference between the average pre-test and post-test scores of the experimental and control groups in the variables of continuous attention (p=0.001) and visual-motor perception (p=0.001). This means that neurofeedback training was effective in improving continuous attention, working memory and visual-motor perception.

The use of neurofeedback is recommended in improving continuous attention and visual-motor perception in elementary school students with special learning disorders.

The present study aimed to determine the effectiveness of cognitive rehabilitation on improving reaction time, planning and response inhibition in bipolar patients. This research was a semi-experimental design with pre-test-post-test and control group. The study population consisted of patients with bipolar disorder who referred to psychiatric specialists, clinics and specialized centers of psychiatric services in Tabriz city in 2022 (October to March). Using convenience sampling method, 40 subjects were selected and randomly assigned in experimental and control groups (15 subjects in each group). They were assessed by Mania-Young Scale, Continuous Visual Performance Test (CPT-V), Chronoscope device (reaction time), Tower of London test. The experimental group received cognitive rehabilitation for 6 sessions and no intervention was applied to the control group. Finally, the post-test was implemented. Data were analyzed by Multivariate analysis of Covariance. Results showed that cognitive rehabilitation was effective in improving reaction time, planning and response inhibition in bipolar patients. Consequently, it could be stated that in improving the cognitive abilities of bipolar patients, the application of rehabilitation could provide appropriate setting for other therapeutic interventions.

The present investigate was conducted with the aim of the effect of cognitive fatigue on working memory and executive functions in female students.

The present study was a quasi-experimental study with pretest-posttest design with a control group,The statistical population of this research includeds the female students of the first secondary school in Urmia city in the academic year of 1400-1401,which is available by random sampling method 30 students selected and were simple randomly divided into two experimental (n=15) and control groups (n=15). The experiment consisted of second phases.In the first stage, the participants were exposed to cognitive tasks and then in the second stage, the Behavior Rating Inventory of Executive and N-Back working memory test was performed to compare the groups based on the amount of cognitive fatigue.The data were analysed by analysis of Covariance.

The results of data analysis using covariance analysis showed decrease in working memory and executive functions in the experimental group compared to the control group.

In general, the findings of the current research on the role of cognitive fatigue variables, which reduces the amount of working memory and executive functions And on the other hand, this type of fatigue is related to cognitive and brain functions.

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.
