Abstract
The purpose of this study was to compare the effectiveness of emotional working memory training and neutral working memory training on improving cognitive functions and decreasing test anxiety symptoms in a group of university students. 60 students with high test anxiety were selected with Spielberger test anxiety inventory. Subjects were divided into three groups: emotional working memory training, neutral working memory training and control. Subjects in the experimental groups received 15 minutes of 45 sessions of emotional and neutral working memory training, while the control group received no intervention. All participants were assessed before and after training using Spielberger test anxiety inventory, Wechsler Digit Span Test, and continuous performance test. Data were analyzed using multivariate analysis of covariance in SPSS-22. Result showed that the subjects in the emotional working memory and he neutral working memory group had a significant improvement in the symptoms of anxiety, direct and inverse Digit Span Test, omission error, commission error and reaction time compared to the control group. The results also showed that the subjects in the emotional working memory group had higher improvement in Emotionality (emotional component of test anxiety) and presentation error compared to the neutral working memory group. Based on the results of the present study, the use of working memory-based computer training, especially emotional working memory, can be suggested as an effective intervention to reduce test anxiety symptoms and improve working memory and sustained attention.

Abstract
Multiple sclerosis is a de-myelinating inflammatory condition of the central nervous system that is often thought of as an autoimmune disorder. These patients suffer from extensive cognitive impairments such as poor attention and concentration and memory and processing speed; Therefore, the aim of this study was to investigate the anodic effect of direct cortical electrical stimulation (tDCS) on sustained attention performance in patients with multiple sclerosis (MS) in a pretest-posttest design with a control group. For this purpose, 32 patients with MS were selected using available sampling method and randomly assigned to experimental and control groups. The intervention consisted of 10 sessions of direct electrical stimulation during which patients were divided into two groups, one group received real stimulation and the other group received sham stimulation or sham. The research instruments were the use of RTI and RVP subtests in CANTAB test. Data analysis was performed based on independent and dependent t-test to compare pre-test and post-test scores in experimental and control groups. The results showed an improvement in sustained attention and processing speed in the experimental group at a significant level of 0.05. Therefore, we conclude that transcranial electrical stimulation of the brain improves sustained attention deficit and speed of response in patients with MS.

Abstract
This research aimed to compare the effectiveness of mindfulness-based socio-emotional learning program with/and without Transcranial Direct Current Stimulation on sustained attention and response inhibition in children with attention deficit/hyperactivity disorder. This research was a semi-experimental study with a pre-test and post-test design with a control group. The statistical population included all students aged 11 to 14 who referred to child and adolescent counseling centers in Khoy city in 2021-2022 year. 45 people with attention-deficit/hyperactivity disorder of the mixed type were selected from among those who refer to the treatment centers by the purposeful sampling method and randomly replaced in two experimental groups and one control group. The first experimental group received the mindfulness-based socio-emotional learning program combined with Transcranial Direct Current Stimulation and the second experimental group received the mindfulness-based socio-emotional learning program for 8 weeks, but the control group did not receive any intervention. All participants were measured before and after the training using continuous performance test and GO/NO-GO test. For data analysis, multivariate covariance analysis was used in SPSS program. Data analysis showed that mindfulness-based socio-emotional learning combined with Transcranial Direct Current Stimulation compared to the other two groups and mindfulness-based socio-emotional learning compared to the control group were more effective on sustained attention and response inhibition. According to the findings, it can be suggested that the mindfulness-based socio-emotional learning program combined with Transcranial Direct Current Stimulation is an effective intervention to improve the cognitive functions of children with attention deficit/hyperactivity disorder.

Abstract
In recent years, the dramatic increase in the use of smartphones has led to the emergence of a psychological disorder called nomophobia, which can have consequences for individual's cognitive functions. The aim of this study was to compare sustained attention and selective attention between nomophobic and normal individuals. The research method was descriptive-comparative, and the sample included 60 students of Semnan University who were identified through screening among a group of 120 students and were divided into two groups of 30 nomophobic and normal. The research instruments included Nomophobia Questionnaire, Continuous Performance Test (CPT) and Stroop Test. Data were analyzed using two-way MANOVA in SPSS software version 26. The results of the Continuous Performance Test showed that the amount of Omission error and reaction time of nomophobic individuals was higher than normal performance individuals. In the Stroop test, the rate of errors and the interference score of nomophobic individuals were higher than normal individuals. Also, despite gender differences in some components of the continuous performance and Stroop tests, it was found that the interactive effect of nomophobia and gender on the results of these two tests is not significant. These results show that nomophobia can be involved in reducing sustained attention and impaired selective attention regardless of gender. Therefore, because of the continuous interaction of people with smartphones and the significant prevalence of nomophobia among young people, measures should be taken to prevent nomophobia and cognitive rehabilitation of nomophobic people.
