Abstract

The aim of current study was to investigation the Compare executive functions and cognitive interpretation bias and cognitive estimation in social anxiety disorder patients and healthy controls. In this study, the sample was 100 students with Purposive sampling method selected from public university from the city of Tehran. This means that the first explanation was given about the research and the cooperation to sample every five Social Phobia Inventory (SPIN), Cognitive estimation, Cognitive Abilities Questionnaire  and، Interpretation bias Questionnaire. Then 50 people who score above the cut-off point in Social Phobia Inventory And in the range of subclinical and clinical, and 50 people who score below the cut-off point gained in social anxiety questionnaire formed the sample. The data was analyzed through multivariable analysis of variance. In sum, the finding of current study Interpretation bias in social phobia patients is higher than normal Individuals and cognitive estimation and executive functions in individuals with social anxiety disorder compared to healthy individuals is flawed.  So that students with social anxiety disorder have lower performance in the components of other groups of students. This problem must be identified and targeted intervention.

Abstract

The current research was conducted by the aim of studying the moderator role of age, Intelligence, and gender in relation to the Executive functions and reading function of elementary students.The sample included 250 students (124 boys and 126 girls) in elementary level that were selected by Multi-stage cluster sampling method among students of Karaj. Different functions were measured as these: Reading through reading test of Karami-noori and Moradi, intelligence by Raven's Progressive Matrices, working memory by Memory span test, attention by Continuous Performance Test, and planning and inhibition by Behavior Rating Inventory of Executive Functions (brief). Statistical methods of Pearson correlation and regression analysis were used.The correlation results showed that there is a positive and significant relation between executive functions (working memory, inhibition, subjective planning, and attention) and reading. Regression analysis result showed that intelligence and gender have not a moderator role in the relation of executive functions and reading.  But, age had a moderator role in the relation of executive functions and reading. The results of this research was consistent with Miyake's theory that believes executive functions are separate but related to each other, and individual differences of the students in these functions should be considered, because they affect their school performance.

Abstract

Aim: The being of impairments in executive functions could lead to weakness individual control on health behaviors and cigarette consumption. The aim of present research was to investigate effectiveness of comprehensive intervention in order to retraining executive functions in smokers. Method: A randomized controlled trial design with pre-posttest and two monthly follow up was applied. The study population included all smoker men in the summer 2016 in Gorgan city. A number of 60 eligible adult smokers were chosen according to specific inclusion and exclusion criteria of the research and were randomly divided into experimental and control groups. The Fagerstrom questionnaire for assessment of cigarette dependence was administered to two groups people. The experiment group then received 10 sessions (twice weekly) retraining of executive functions (Working Memory and Inhibitory Control), whereas in the control (placebo) group a placebo intervention like the original tasks were performed. The Fagerstrom questionnaire was again performed at post-test and in one month and two month follow up stages in both groups. Results: A repeated measure GLM: Multivariate Analysis of Variance showed significant differences between two groups in Fagerstrom in posttest and two follow up stages. Conclusion: Overall, the retraining executive functions intervention was effective on cigarette dependency and could use from this intervention in cigarette treatment programs.

Abstract
Working memory is the comprehensive cognitive system that embedded attentional and memorial mechanisms and therefore can be used in systematic research of cognitive problems. Accordingly, the aim of this study was to investigate the developmental changes of working memory capacity, and its components, including phonological loop, visuospatial sketchpad, and central executive (inhibition and updating). A total of 356 children (8 and 12 years) recruited from primary school in Tehran were selected and tested. Digit Span, and the Kim Karad Visual Memory Test were used for measuring phonological loop and visuospatial sketchpad. Working memory capacity was measured by Backward Digit Span, and finally, the Stroop Task, and the Keep Track task measured central executive. Data analyzing showed as child growth, working memory and its components become more effective. More skills in arithmetic abilities, more flexibility in storage and processing, more experience in academic achievement and more use of metacognitive strategies can be possible reasons for the results of this study.

Abstract

Depressed people, unlike non-depressed, show the higher the right frontal lobe activity than the left frontal lobe. Because the right hemisphere associated with negative emotional processing, pessimistic and maladaptive thinking styles, and the frontal alpha power is the inverse index of cortical activity, the frontal alpha power asymmetry reflects the balance between the left and right hemisphere in the frontal. The aim of this study was to improve the frontal alpha asymmetry for reducing depression and rumination levels and executive functions of people with reactive depression from love trauma syndrome through the neurofeedback interventional method and compare its efficacy with the sham group. In addition, in this study, was considered the neurological characteristics of the emotionally traumatic experience, through the Clinical Q as the evaluation method. This study's participants include 32 students of Tehran and Amir Kabir universities that they experienced love trauma in the recent 6 months and subsequently, they exposed depression and rumination symptoms and reduction of executive functions. For measuring of Pre-Test phase, after the primary interview and performance of Love Trauma, Beck's Depression and Anxiety Scales was evaluated executive functions (continuous attention, working memory and cognitive inhibition) by computer tasks; CPT, N-Back and Go/NoGo. Finally, was measured EEG 2-channel record through Clinical Q. The participants were placed in the trial group (age: M=24.73, SD=3.71) and sham group (age: M=23.46, SD=2.87), randomly. Then, in the neurofeedback intervention performance, was exerted 15 sessions on 45 min in the both of the trial and the sham groups. At the end of sessions were repeated pre-test phase measurements for post-test phase. Results of this study, emphasize on the effects of alpha asymmetry neurofeedback for reduction of depression symptoms similar to some research and against, deferent of other some studies, such as effective neurofeedback training for the decrease of Beck's depression scores. One of the important results of this research was the improvement of executive functions and rumination, the reason of substantial role of the both on depression duration. Effect of frontal alpha asymmetry neurofeedback on the reduction of love trauma and also, improvement of the neurological index of traumatic event experience was a new finding. Based on this results could be proposed neurofeedback training as a beneficial intervention for reduction of love trauma syndrome.

Abstract

Treatment of attention deficit / hyperactivity disorder as the most common neurodevelopmental disorder has tended toward the use of computer-based technologies. The purpose of this study was to investigate the effectiveness of computer-based cognitive rehabilitation on the executive functions of children with attention deficit / hyperactivity disorder. The study was a quasi-experimental with pretest posttest and 45 days follow up with control group. The statistical population consisted of all students with attention deficit / hyperactivity disorder in Shiraz elementary school in winter of 2019. 32 students were selected as available sample and replaced in experimental and control groups. The Tower of London test, the Stroop test, and the Wisconsin Card Sorting Test were used. The experimental group received cognitive rehabilitation based on computer games three times a week (15 minutes per game for a total of 30 minutes) and the control group was placed on the waiting list. Data were analyzed by SPSS-24 software using repeated measures analysis of covariance (ANOVA). The results showed that computer-based rehabilitation had a significant effect on the executive functions of children with attention deficit / hyperactivity disorder (Sig <0.05). Experimental group showed improvement in cognitive function after intervention and planning, organization, inhibition and cognitive flexibility variables were observed after 45 days of intervention. Therefore, it can be said that cognitive rehabilitation is based on effective and sustained therapeutic computer games.

Abstract

The aim of this study was to investigate the effect of Cognitive rehabilitation traning (CTR) on Executive functions and attention in students with lrarning problem. In an experimental study with pre-test, post-test and control group, 42 students with LP were selected through convenient sampling method. They were randomly assigned to the experimental and control groups. The experimental group underwent two months’of intervention and the scores of the Behavior Rating Inventory of Executive Functions (BRIEF), and the Stroop Color and Word Test (SCWT) were gathered in both groups before and after the intervention and in one month follow up. The data was analyzing by the statistical test of mixed variance analysis. The results in the post-test and follow-up stages showed that there is a significant difference between the two experimental and control groups, in terms executive functions, and attention. This means that the experimental group who underwent the intervention program had significant improvement in the post-test phase in terms of executive functioning and attention. the changes made during the follow-up phase remained consistent. Also, based on the results obtained, cognitive rehabilitation intervention did not significantly affect the emotional regulation index of students with the LP. The results of this study indicate the effectiveness of a designed cognitive rehabilitation program on executive function, and attention of students with LP; therefore, considering these findings and the mechanism, the effectiveness of this intervention method can have appropriate therapeutic effects on reducing cognitive and psychological problems and improving the quality of life of student with LP.

Abstract

The aim of this study was to investigate the effect of training neuropsychological executive functions on metamemory, planning and problem solving in students with mathematics disorder. This research is semi-experimental and its design includes pre-test and post-test as well as a control group. The population of this research were female students with mathematics disorder from the third to sixth grade of primery school, who had been to the Isar Specialty Learning Problem Instruction Center in 2017-2018. Thirty of them were selected by available sampling and were divided into experimental and control groups. Initially, both groups were tested by Wechsler Intelligence Test and K-Mathematical Test. Both groups were assessed by pre-test and post-test using the Metamemory Questionnaire and the Tower of London Questionnaire. The experimental group received 10 sessions for 3 months, while the control group did not receive any training. The results of multivariate analysis of covariance indicated that there was a significant difference between the two groups in terms of metamemory, planning and problem solving. This means that training executive functions has been able to increase the amount of metamemory, planning and problem solving for students with mathematics disorder. The results of this study can be used in the education and treatment of students with mathematics disorder and executive functions should always be considered as a key factor.

Abstract

The aim of this study was to evaluate the effectiveness of mindfulness and the attention bias program on attention, inhibition and emotional regulation among children with generalised anxiety disorder. This was a quasi-experimental study with a pretest-posttest design. The population of this study consisted of 30 children with generalised anxiety disorder referred to psychiatric clinics in Tehran's 20th district selected by the available sampling method and randomly divided into experimental and control groups. The experimental group underwent an integrated program of attention correction and mindfulness for 8 sessions and the control group did not receive any intervention. In addition, parents of all participants completed the brief executive functions test at pre-test and post-test. Data were statistically analysed at two levels of descriptive (mean and standard deviation) and inferential (multivariate analysis of covariance). The results of this study showed that the program of correcting attention bias and mindfulness had an effect on the amount of attention, inhibition and emotion control among children with generalised anxiety disorder (p < 0.001). According to the findings of this study, it could be concluded that the combination of the treatment of attention bias and mindfulness improves executive functions in children with generalized anxiety and can be used in clinical interventions.

Abstract

Computer-based cognitive games are new and exciting for kids and adolescents that can help them to improve their cognitive functions and creativity in addition to entertainment. The aim of the present study was to investigate the effectiveness of computerised cognitive games on executive functions and creativity of preschool children. This study is a quasi-experimental study with a pre-test, post-test, and control group design. The sample consisted of 21 preschool female and male children, who were selected by convenience sampling in a preschool centre in Bushehr. Participants were matched on the basis of gender, age and intelligence and were allocated to three groups of seven children, i.e., two experimental groups and one control group. Before and after cognitive games, the Torrance Tests of Creative Thinking (TTCT), a simple Stroop software and the working memory Wechsler Memory Scale (WMS) were used. The experimental groups played cognitive games such as Lomocyte and Tetris for 16 one-hour sessions, and the control group did not play any games during this time. The results showed that playing computerised cognitive games has a significant effect on creativity and working memory among preschool children. However, there is no significant effect on selective attention, cognitive flexibility, planning and organising. The results of this research have important theoretical and applied implications regarding the role of computerised cognitive games in promoting cognitive functions of preschool children.

Abstract

The importance of understanding the pathology, nature, and treatment of Autism Spectrum Disorders (ASD) has always been emphasised throughout school. Children with ASD have difficulties in verbal and non-verbal social communication, which limit their ability regarding effective social communication and academic achievement. The purpose of this research was to compare learning strategies and executive functions among successful and non-successful autistic students in terms of academic achievement. For this purpose, 15 successful students with ASD and 15 non-successful students with ASD were recruited via the purposeful sampling method. The Autism-Spectrum Quotient Test, the executive functions and learning strategies questionnaires were used. Data was analysed with an independent t-test. Results showed that, successful students with ASD had a significant difference with the second group in all variables of learning strategies in addition to inhibition, emotional management, planning, organizing and attention shifting. It can be concluded that students with ASD who are successful in education use more learning strategies and have better executive functions compared with autistic students who are not successful in education.

Abstract

the children with attention deficit/hyperactivity disorder (ADHD)  in executive functions such as kinds of attention, response inhibition and response rate cope with problems which need therapeutic and educational plans to improve. From this kind of methods, cognitive rehabilitation is a new approach, which its effectiveness has studied in various cases. The aim of this study is to find out the effect of Computer- assisted cognitive rehabilitation on improving of executive function of students with attention deficit/hyperactivity disorder. This study is a kind of quasi-experimental design with pre-test / post-test and control groups. 30 students come down with attention deficit/hyperactivity disorder (ADHD) selected by the available sampling method and base on criteria for entering of referrals to medical centers. 15 students were in experimental groups and others in control group. Experimental group have received training and computer-assisted Cognitive Rehabilitation for 15 Sessions. the integrated visual and auditory (IVA) continuous performance test, raven's progressive matrices test for children 5 to 9 years, SNAP-IV rating scale the Swanson questionnaire and Captain's­Log Cognitive Rehabilitation software. Data has analyzed by analyze of covariance method. the results of this study revealed that improving executive functions, response inhibition variables, sustain attention, self-centered attention and selective attention were caused by Cognitive Rehabilitation by computer game (P=0.05). But, significant Improvement was not observed in two variables, response rate and divided attention. (P=0.05). Ognitive Rehabilitation by Captain's­Log computer game affected on improving of executive functions of students with attention deficit/hyperactivity disorder so if the children with disorder being train under Cognitive computer software, executive functions of them will improve on response inhibition components, self-centered attention, selective attention and sustain attention.

Abstract

This study examined the associations among the executive functions, family cohesion, positive youth development and emotional maturity in adolescents, as well as the mediating role of emotion regulation in the relationship between executive functions, family cohesion, positive youth development and emotional maturity. Participants of this study included 300 high school students in grades 10 to 12 from six schools in Qom, Iran who completed the BRIEF2 Scale, the FACES IV, Positive youth development–short form, Emotional maturity questionnaire and Emotion Regulation Scale. Structural equation modeling revealed was positively associated executive functions with family cohesion, emotion regulation with emotional maturity and positive youth development. Also, the results indicated that no significant relationship between emotion regulation and family cohesion. Interaction-mediation analysis demonstrated that emotion regulation in the relationship between executive functions and family cohesion plays a full mediating role and in the relationship between executive functions and positive youth development and in the relationship between executive functions and emotional maturity has minor mediating role.  In generally, attention to the findings in this study can be used by researchers and therapists in the design and application of effective cognitive and psychological interventions to reduce the problems and mitigate the crises facing adolescents.

Abstract

Executive functions are important structures that play an important role in controlling and directing behavior. This research was conducted with the aim of investigating the mediating role of emotional intelligence in the relationship between theory of mind and executive functions (cognitive flexibility and response inhibition). The current research method was correlation and structural equation modeling. The statistical population of the research included all female students aged 13 to 18 in Khomeini Shahr city in 2021, of which 300 were selected for the research sample using the available method. To collect data from the emotional intelligence questionnaire (Schutte et al., 1998), software tests of Wisconsian card sorting (Grant and Berg, 1984), go /no go (Hoffman, 1984) and mind reading through eye images (Baron-Cohen et al., 2001) were used. For data analysis, Pearson's correlation coefficient and structural equation model were used in AMOS-24 software. The findings showed that theory of mind had a positive and significant direct effect on emotional intelligence with a coefficient of 0.233 and on cognitive flexibility and response inhibition with a coefficient of 0.133 and 0.218 respectively (P<0.01), intelligence Emotion with cognitive flexibility and response inhibition had a positive and significant direct effect with coefficients of 0.144 and 0.337 respectively (P<0.01). The indirect effect of theory of mind on flexibility and response inhibition with the mediating role of emotional intelligence was 0.033 and 0.078, respectively. Therefore, the results indicated the decisive role of theory of mind and emotional intelligence in predicting cold executive functions (cognitive flexibility and response inhibition). Finally, considering the relationship between theory of mind, emotional intelligence, cognitive flexibility and response inhibition, by increasing theory of mind and emotional intelligence, it is possible to help improve the components of executive functions.
