Abstract
Pharmacological treatment of adult with attention deficit with hyperactive disorder (ADHD) has been shown to be successful; however, medication may not normalize executive functions. The present study was assessed the effect of working memory training program on executive functions of adult with ADHD. Sixteen adults with ADHD and 16 healthy adult participated in the study. After a diagnostic and baseline evaluation, 16 adults with ADHD participate in up to 16 sessions of working memory training program and the outcomes are evaluated. Healthy people did not receive any training. Working memory and attention, were examined prior to and following the interventions. Data analysis revealed that the working memory training used in the present study led to significant improvements of various aspects of attention, including focus and sustain attention and capacity of working memory. The findings indicate that working memory training programs can improve working memory performance and have the potential to facilitate attentional functioning in adult with ADHD as well.

Abstract
The aim of this study was to evaluate the effectiveness of cognitive rehabilitation on improving working memory of adolescents with traumatic brain injury. The method of this research was quasi-experimental pre-test-post-test with control and follow-up groups. To conduct this study, 20 adolescents aged 9-18 years with traumatic brain injury referred to medical centers in Sadaf Shahriar (Parandmehr Clinic) were selected by convenience sampling and randomly assigned to two groups of 10 experimental and control. To measure the dependent variable of working memory, Wechsler scale 4 subtests (auditory measurement of working memory) and Benton test (visual-spatial measurement of working memory) were used. The experimental group underwent cognitive rehabilitation intervention (12 sessions of 45 minutes). Analysis of variance with repeated measures was used to analyze the data. The results showed that there was a significant difference between the experimental and control groups in pre-test, post-test and follow-up of working memory performance. The results showed a significant difference between the mean scores of working memory (auditory and visual-spatial measurements) of the experimental group and the control group in the post-test. In addition, there was no significant difference between post-test scores and follow-up in the experimental group, which showed the effect of cognitive rehabilitative perstability on working memory performance in adolescents with brain injury. Therefore, cognitive rehabilitation has a significant effect on improving working memory performance in patients with brain injury and can be used as an effective and useful method to improve working memory performance in adolescents with brain damage.

Abstract
| People with borderline personality disorder experience problems in a variety of cognitive areas, including information processing, decision making, planning, memory, and problem solving. The aim of the study was to modeling the intermediate role of metacognitive awareness on the relationship between overgeneral autobiographical memory and problem solving. The research was fundamental and in terms of implementation method was correlational. The statistical population included all individuals with borderline personality disorder who referred to psychological and psychiatric clinics in Kurdistan province in 1397-98. 300 patients with diagnosis of borderline personality disorder based on clinical interview and willing to participate in the study were selected. They answered the Autobiographical memory test, metacognition awareness questionnaire and social problem solving inventory. Data were analyzed using Amos software. Findings showed that overgeneral autobiographical memory has a direct effect on problem solving skills and metacognitive awareness with coefficients of 0.17 and 0.20, respectively. Also, the direct effect of metacognitive awareness on problem solving was 0.35. Overgeneral Autobiographical memory predicted 4% of the variance of metacognitive awareness, and Overgeneral autobiographical memory with metacognitive awareness predicted 17% of problem-solving changes. On the other hand, the indirect effect of Overgeneral autobiographical memory on problem-solving skills was 0.07, which shows that the indirect effect of Overgeneral autobiographical memory on problem-solving skills is significant. Therefore, it can be concluded that metacognitive awareness acts as a mediator as an observer, which increases the scores of problem-solving skills. |

Abstract
| Due to the importance of rehabilitation among children with special learning disabilities, the aim of this study was to evaluate the effect of brain Gym on suppression of theta/alpha ratio and working memory of students aged 8 to 12 years with dyslexia or dysgraphia. This research was a quasi-experimental study with a pre-test and post-test design with a control group. The population of this study included all girls and boys with reading or writing disorders referring to special centers for learning disabilities in Kermanshah. The convenience sampling methods were used. For this purpose, according to the inclusion and exclusion criteria, 20 students aged 8 to 12 years were selected and randomly allocated into two groups of 10 people. The experimental group were received brain Gym intervention for 20 sessions of 20 minutes over 10 weeks. In order to record the brain waves of the participants, a dual-channel neurofeedback device was used. Moreover, the Wechsler memory software was used to measure their active memory. To analyze the data, univariate one-way covariance analysis and multivariate one-way covariance analysis were used using SPSS software version 26. The results showed that the ratio of theta waves to alpha in the experimental group was significantly reduced and active memory span in the experimental group was significantly increased compared to the control group (P < .05). The findings of this study indicated that brain exercise can significantly suppress the ratio of theta waves to alpha and also improve working memory among children with special learning disabilities. The findings confirm the neurological evidence for the positive effect of the brain Gym intervention on the modulation of brain waves and working memory in children with dyslexia or dysgraphia. |

Abstract
Reduced specificity of memories is one of the significant cognitive processes in depression. The aim of this study was to reduce the symptoms of depression and sedentary behavior in female adolescents with depressive disorder through memory specialization training. This research was applied in terms of purpose and quasi-experimental method with pre-test, post-test with control group. The statistical population of this study included all students of 4 public and private schools in Kermanshah in 1400 who were selected by cluster random sampling. Depression test (Rindells, 1989) and sedentary behavior (Fisher et al., 2012) were then performed on 350 students of these 4 schools. From 67 students with depression higher than 60 and inactivity higher than 11 hours and 40 minutes per week, 30 were selected based on inclusion criteria and available in a simple random method in two experimental groups (15 N) and control (n = 15) were assigned. Then, the experimental group underwent memory specificity training (Rise, 2009), which was conducted in 6 group sessions of 90 minutes per week. The results of this study showed that the memory specificity training can reduce Mobility and depressive symptoms were significant at the level (P = 0.001) in female adolescents with depression. Generally, it can be concluded that autobiographical Memory Specificity Training is an effective way to reduce depression and Sedentary behavior. Due to the ease and a low number of sessions, this training can be used along with other treatments to reduce the vulnerability to depression.

Abstract
The process Assessment of the Learner-Second Edition: Diagnostic Assessment for Math is one of the most widely used tests in the field of learning disorders, which has two versions: reading, writing, and math. The purpose of the present study was to investigate the educational and cultural adaptation of this test. For this purpose, after the translation of the test, the stages of cultural adaptation were investigated from three sources of elementary school mathematics textbooks, interviews with teachers and test implementation of the test on a group of 14 children from preschool to sixth grade, applicability and Special criteria for the implementation of the test were prepared for Iranian students. There has been an amendment to the content of the Iranian sample test in terms of the items of multi-step problem-solving and part-whole concepts. Also, the criteria for passing the test for Iranian students in the sub-tests of place value, finding the bug, and the ability to perform calculations are placed at a higher age than the main instructions of the test. Geometry and decimal numbers are items that are covered in the Pal_II math test in the form of part_whole concepts. However, it is more detailed and complicated in Iranian math textbooks. Calculation education in Iran's school education system has undergone changes in recent years, which were revised in the test instructions. The similarities between the implementation and grading of the Persian version of the Pal_II math test in the Iranian sample and the original instructions of the English version of the test are more than the differences between them.

Abstract
This study aimed to comparison of the effect of Transcranial Direct Current Stimulation (tDCS) and Transcranial Random Noise Stimulation (tRNS) combined with cognitive training on working memory performance of people with attention deficit/hyperactivity disorder. For this purpose, 45 children with attention deficit hyperactivity disorder in zahedan city were purposefully selected as the research sample. Subjects were divided into three groups: tDCS, tRNS and placebo group. Subjects in the experimental groups received 5 sessions of electrical stimulation (tDCS and tRNS) with an interval of 24 hours between each session; placebo group also received fake stimulation (non-effective). At the same time, all subjects also received cognitive rehabilitation of working memory. All subjects were evaluated before and after the stimulation and one week after the stimulation using the N-back task and the Wechsler Digit span test. The data were analyzed using repeated measures analysis of variance. The results showed that in the tDCS group, there was a significant difference in most working memory components from the pre-test stage to the follow-up (p<0.001). In the tRNS group, a significant difference was found in the component of direct digit span and reverse digit span in the research stages. In the comparison between the two experimental groups, the effectiveness of the tDCS group was higher than that of the tRNS group. Also, no significant difference was found in most of the components between the tRNS and placebo groups (p>0.05). Overall, the results of this study show that tDCS was more effective than tRNS in working memory and this method can be used together with other treatments to improve the working memory of children with attention deficit/hyperactivity disorder.

Abstract
The aim of this study was to investigate the effect of mindfulness-based education on two structures related to cognition, namely self-blame and working memory in adolescents. The research design was quasi-experimental with a control group. Participants included 30 people (two groups of 15 people) from adolescents aged 14 to 18 years who volunteered to participate in the study. They responded to the Thompson and Containers' Self-Blame Levels (2004), and the Wechsler Active Memory Scale (1945) as pretest and posttest. The experimental group participated in a mindfulness-based stress reduction program for 8 sessions, each session lasting 2 hours and the control group was without intervention. Data were analyzed using analysis of ANCOVA. The results showed that mindfulness intervention had a significant effect on self-blame (P = 0.001) and working memory (P = 0.001) in the experimental group (P <0.05).
In a general conclusion, it can be stated that mindfulness-based education can be used in therapeutic and psychological programs to increase working memory and reduce self-blame in adolescents.

Abstract
Dysgraphia is one of the common symptoms of specific learning disorders. children with dysgraphia have several cognitive problems. This research was conducted with the aim of investigating the effectiveness of HAMRAH cognitive rehabilitation package on improving executive functions (working memory and response inhibition) in children with dysgraphia. The present research was semi-experimental in the form of pre-test-post-test with a control group. The statistical population of the research was students with dysgraphia who referred to education counseling centers in Kermanshah city in 1401. Among them, 40 people (initially 20 people in the experimental group and 20 people in the control group, but one of the control group was removed by the end of the experiment) who were willing to cooperate and were also available were selected and then randomly divided into experimental and control group. Then, in both groups, the pre-test was implemented, and after that, the experimental group received 12 intervention sessions of the HAMRAH cognitive rehabilitation package, but there was no intervention for the control group. Then, a post-test was performed for both groups. The data were analyzed using covariance. The results showed that the Hamrah cognitive rehabilitation package has an effect on improving working memory and response inhibition in children with dysgraphia (P<0.01). It is suggested that the HAMRAH cognitive rehabilitation package be used in medical centers by mental health specialists, along with other treatment methods, in order to improve working memory and response inhibition for children with dysgraphia

Abstract
Stress is an integral part of human life today, so most people have learned relatively adaptive ways to deal with it, these methods are usually enough to cope with the stresses of everyday life, but sometimes there are events that cause too much stress to cope with. This study aimed to evaluate the comparison of personality characteristics and autobiographical memory among individuals with Post-traumatic Growth and those suffering from post-traumatic stress disorder. Method of this study is causal-comparative. The study population included all of the patients who refer to hospitals of Isfahan after having a vehicle accident. For the screening phase post-traumatic stress disorder inventory (PTGI) and PTSD checklist (PCL) were used. 22 persons for the PTSD group and 20 persons for the PCL group were selected purposively. Both these groups answered the Autobiographical memory test (AMT) and the short form of the Five-factor model. The analysis illustrates there are meaningful differences between these PTSD and PTG groups in neuroticism, extraversion, openness, and conscientiousness subscales in addition to Autobiographical memory, but there were no meaningful differences between these two groups in agreeableness.

Abstract
According to the existing classifications of Raven's Colored Progressive Matrices (RCPM) test, it is shown that RCPM is not a homogeneous test and various cognitive factors are involved in it. Moreover, success in RCPM is influenced by working memory ability. Therefore, the present study aims to compare the three factors of the RCPM test in two groups of students with weak and strong visuospatial working memory (VSWM) and examine their role in each of the existing components.
This research evaluated a sample of 150 female students aged 6 to 10 years. Initially, after obtaining consent from the students, the school, and the parents, each student took the RCPM test. The score for each question was recorded as either correct or incorrect, and the total correct responses for each factor were calculated. Subsequently, the Corsi block span test was conducted to assess VSWM, and the score for each participant was recorded. Based on the scores of Corsi block span test, the participants were divided into two groups with strong and weak VSWM, and each factor was individually examined in these two groups.
The results showed that the differences in two factors of the RCPM test in the two groups with strong and weak VSWM are statistically significant. Reviewing the literature shows that differences in VSWM can explain success in the first (involving similarity) and second (Gestalt principles) factors. However, the examination of the third factor (involving concrete and abstract reasoning) yields contradictory results in previous research. This research is the first study to focus on the difference in VSWM in the triadic factors of the RCPM test. It is recommended that in future research, the relationship between the factors of the RCPM test and other cognitive functions be examined, and the roles of gender and age be considered.

Abstract
The present study investigated the effect of attention and memory training and improvement software on cognitive ability and emotion regulation in patients with corona virus after recovery. The present research project is a pre-test-post-test experiment with a control group. The statistical population of this research included all the residents of Shadegan city who were hospitalized in the first half of 2021 due to the corona virus in Shahid Moarefi Zadeh hospital (exclusively for corona patients) and then recovered. According to the research design, the sample size was 40 people, who were placed in 2 groups of 20, test and control groups (20 people in test group and 20 in control group) and were selected by simple random sampling method and randomly placed in test and control groups. Also, only the test group was intervened with attention and memory training and improvement software, and finally both groups answered the questionnaires (post-test) again. The research tools were the Garnefski`s Cognitive Emotion Regulation Questionnaire, Nejati`s Cognitive Capability Questionnaire, and attention and memory training and improvement software. Also, descriptive statistics such as mean and standard deviation, minimum and maximum scores and inferential statistics such as; Levene test and covariance analysis were used to analyze data using SPSS software version 24. The results of covariance analysis of the data have shown that there was a significant difference between the experimental and control groups in each of the dependent variables (P<0.001). That is, the average of the cognitive regulation of emotion and cognitive ability and all the components of these two variables have increased significantly in the experimental group compared to the pre-exam and the control group. Therefore, it can be said that the attention and memory training and improvement software has had a significant impact on the cognitive ability and emotion regulation of recovered patients of corona virus.
