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
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
HIV is associated with extensive physical and psychological consequences, significantly affecting the quality of life of patients. Cognitive rehabilitation is a novel intervention aimed at improving cognitive and psychological functioning in these individuals. The present study aimed to evaluate the effectiveness of cognitive rehabilitation intervention on reducing depression, improving working memory, and enhancing attention in patients with immune deficiency. This quasi-experimental study utilized a pretest-posttest control group design and was conducted in Izeh, Iran, in 2023. A total of 30 patients with HIV were selected through purposive sampling and randomly assigned to experimental and control groups (15 participants per group). Instruments included the Beck Depression Inventory, Working Memory Assessment, and Continuous Performance Test to measure attention. The experimental group underwent 12 sessions of cognitive rehabilitation (60 minutes each, three times a week), while the control group received no intervention. Posttests were administered to both groups after the intervention. Data were analyzed using multivariate covariance analysis (MANCOVA) in SPSS.23. The results showed that cognitive rehabilitation significantly reduced depression and improved working memory and attention in the experimental group compared to the control group (P ≤ 0.001). These findings suggest that cognitive rehabilitation is an effective approach for enhancing cognitive and psychological outcomes in patients with immune deficiency and can be utilized in therapeutic settings.

Abstract
This study was conducted with the aim of comparing the effectiveness of sensory-motor games and neurofeedback on the working memory of children with attention deficit and hyperactivity disorder. This research is one of the types of semi-experimental studies in which subjects were selected from all 8-12-year-old children in Tehran with hyperactivity and were randomly assigned to experimental and control groups. 40 subjects were placed in three groups of sensory-motor games, neurofeedback, a combined group, and a control group, and before and after the interventions, the revised Wechsler intelligence scale for children -4th version WISC-R- was used to measure working memory. The findings obtained from covariance analysis after meeting the defaults showed that the amount of working memory in sensori-motor, neurofeedback and combined games in the group and the control are significantly different after removing the effect of the pre-test. This result means that according to the mentioned results, the intervention of sensory-motor, neurofeedback and combined games has a significant effect on the amount of active memory. Also, based on the findings, the combined approach of sensory-motor games and neurofeedback on children's working memory is more effective than the two approaches of sensory-motor games and neurofeedback, and there is a significant difference between the two approaches of sensory-motor games and neurofeedback in their effectiveness on active memory. does not have.

Abstract
High autistic traits in adolescents are associated with a wide range of destructive educational and social consequences. Therefore, it is important to identify the influencing factors. The present study was conducted with the aim of investigating the role of social information processing in the autism spectrum symptoms by moderating working memory, cognitive flexibility and mentalizing.
This research was descriptive and correlational type and was done by structural equation modeling method. The statistical population of the research included all 12th grade students of public schools for boys and girls in Tehran in the academic year 2023-2024, 260 of whom were selected using a multi-stage sampling method. The research tools included the Social Information Processing - Attribution and Emotional Response Questionnaire (SIP-AEQ), the Autism-Spectrum Quotient (AQ), the Reflective Functioning Questionnaire (RFQ), computerized version of the Daneman and Carpenter's Working Memory Task, and the Wisconsin Card Sorting Test. Data analysis was done using Smart PLS 3 software.
The results of structural equation modeling showed that Hostile Attribution Bias (t=2/534 ،β=0/322) and Negative Emotional Responses (t=2/001، β=0/275) have a direct, positive and significant effect on the subclinical symptoms of autism. Mentalizing has a moderating effect on the relationship between hostile attributional bias (t=2/549، β=-0/507) and negative emotional responses (t=3/164، β=-0/632) with subclinical symptoms of autism. Also, the moderating role of working memory in the relationship between hostile attributional bias and subclinical symptoms of autism was confirmed (t=4/389، β=-0/394).
According to the results of the research, the use of Mentalization-Based Treatment (MBT), Working Memory Training and Social Information-Processing Skills Training is suggested to the therapists.

Abstract
The present study aimed to compare recognition memory and memory confidence among individuals with obsessive-compulsive disorder (OCD) subtypes—washing and checking—and generalized anxiety disorder (GAD) using an experimental post-event design. The sample consisted of 45 patients referred to Razi Hospital Clinic in Tabriz in 2023, divided into three groups of 15 each: washing-type OCD, checking-type OCD, and GAD. Participants were aged 20 to 45 years, had at least a high school diploma, and included both genders. Memory was assessed using two computerized word lists, comprising recognition and recall tasks. Data were analyzed through multivariate analysis. Findings indicated significant differences among groups in recognition memory and memory confidence (p < 0.05), with the checking-type OCD group demonstrating poorer performance compared to the other groups. These results highlight the differential impact of emotional disorders on cognitive memory components and emphasize the need for targeted cognitive and psychotherapeutic interventions to improve memory functioning in OCD and anxiety patients.

Abstract
Cognitive biases are influential factors in explaining illness anxiety disorder, and understanding the existing biases in this disorder can contribute to more effective treatments. This study was conducted to examine the biases of attention, interpretation, and memory in individuals with and without illness anxiety disorder. The sample consisted of 142 participants who voluntarily participated in the research from across the country. In this study, differences in information processing between the two groups were assessed using the Health Anxiety Questionnaire, Beck Depression Inventory, and computer-based tasks measuring attention bias, interpretation, and memory. The data obtained from the research were analyzed using independent t-tests and analysis of covariance (ANCOVA) with the statistical software SPSS 26.The results showed that individuals with illness anxiety disorder had a greater tendency to focus on threatening cues compared to those without the disorder and interpreted ambiguous health-related information more negatively. However, no significant differences were observed between the two groups regarding positive interpretation bias. Additionally, individuals with illness anxiety recalled disease-related information more effectively. The findings indicate that individuals with illness anxiety display biases in attention, negative interpretation, and memory concerning health-related information. This research emphasizes the importance of identifying and targeting these biases in psychological treatments and suggests employing intervention methods such as cognitive bias modification to directly affect these biases due to their role in the formation and persistence of illness anxiety.

Abstract
| The present study aimed to analyze the structural model of adolescents’ achievement goal orientation based on theory of mind and working memory within a cognitive-social framework. Using structural equation modeling (SEM), the study investigated the direct and indirect effects of theory of mind on the four dimensions of achievement goal orientation (mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance), with working memory as a mediating variable. The research design was descriptive-correlational, and the statistical population included all high school students (second level) in Qom Province during the 2023–2024 academic year. A sample of 315 students was selected through convenience sampling. Data were collected using the Achievement Goal Orientation Questionnaire (Elliot & McGregor, 2001), the Theory of Mind Questionnaire (Baron-Cohen, 2001), and the Working Memory Test (Daneman & Carpenter, 1980). SEM results revealed that theory of mind significantly predicted achievement goal orientations, both directly and indirectly through working memory. A significant positive relationship was also found between theory of mind and working memory. The model showed a good fit, underscoring the crucial role of cognitive-social processes in shaping adolescents’ academic motivation. |

Abstract
The present study aimed to investigate the effectiveness of Unified Protocol (UP) and transcranial Direct Current Stimulation (tDCS) treatment on working memory and continuous attention in patients with generalized anxiety disorder (GAD). The research design employed a quasi-experimental framework, featuring a pre-test and post-test design with two experimental groups and a control group. The statistical population consisted of patients diagnosed with GAD who sought treatment at clinics and specialized neuropsychiatry centers in Tehran during the first half of 2024. Based on the inclusion and exclusion criteria, a sample of 45 individuals (31 women and 14 men) was selected through purposive sampling and equally allocated (15 individuals in each group) into the UP intervention group, the combined UP and tDCS intervention group, and the waiting list group. The Structured Clinical Interview (SCID-V), the 7-item Generalized Anxiety Disorder Scale (GAD-7), the Corsi Block Test (to assess working memory), and the Clock Test (to assess continuous attention) were utilized as assessment tools. Statistical analyses were conducted using SPSS-26 statistical software, employing analysis of covariance (ANCOVA). The findings indicated that the use of the UP protocol, both alone and in combination with tDCS, led to a significant improved in working memory and continuous attention (P<0.05). Furthermore, this study suggests that both UP intervention and the combined intervention (UP+tDCS) are effective approaches to improve working memory and continuous attention in GAD patients and may serve as a novel strategy for managing this disorder and improving executive functions.
