Abstract
The aim of the present study was to investigate of the efficacy of bilateral repetitive transcranial magnetic stimulation on cognitive function in patients with bipolar depression. In a single-blind experimental trial, 20 patients with bipolar depression who had been referred to Atieh clinical neuroscience center were selected randomly from April to September 2015. The patients received bilateral repetitive transcranial magnetic stimulation on left dorsolateral prefrontal cortex (10Hz) and right dorsolateral prefrontal (1Hz) during 10 sessions. The subjects were evaluated through verbal fluency test, Rey Auditory-Verbal learning Test, Stroop Test, Wisconsin Card sorting Test, Beck depression inventory before and after the treatment. The data were analyzed by paired t test. Bilateral rTMS was caused to significant changes in executive function and verbal memory and depressive symptoms. No significant changes were observed in selective attention and verbal fluency (p>0/05). Bilateral repetitive transcranial magnetic stimulation is caused to significant improvement in cognitive symptoms and reduces the symptoms of depression in patients with bipolar depression.

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
The aim of this research was to determine the effectiveness of tDCS and cognitive rehabilitation of working memory and the combination of these two methods on speed of processing and symptoms of dyslexia on bilingual children. Research method; semi experimental (pre-test, post-test and control group). Research population included all of the bilingual children at both sex at the age of 7-11 in Tehran and Kahrizak cities. Available samples were selected through Wexler intelligent questionnaire and Nama dyslexia test scores, so that 40 dyslexic students (based on school diagnostic system) and situated randomly in 4 groups: a) intervention by tDCS brain stimulation, b) computational cognitive rehabilitation via working memory module of RehaCom, c) simultaneous intervention of computational cognitive rehabilitation and brain stimulation tDCS and d) control group. Nama and speed of processing (SDMT) tests have been performed on all of the four groups in pre-test and post-test in order to data collecting. Data analysis results using analysis of multi-variable covariance in SPSS-22 showed that mentioned interventions could have meaningful changes in speed of processing and in decreasing dyslexia symptoms. Post hoc test results also showed that combination method first of all and then brain stimulation method have been the most effectiveness, but the mere computational cognitive rehabilitation method has not been influenced on these two variables alone.

Abstract
The purpose of this study was to identify the role and application of the concept of metaphor of Lakoff in thinking teaching. This research has been conducted with conceptual analysis method of 30 selected sources in two parts of the technical language and the conventional language. The results of technical language analysis indicate that the role or outcomes of conceptual metaphor in the teaching of creative thinking can be generally divided into two cognitive and social domains. Cognitive outcomes include: developing the skills of reasoning, improving the ability to reason, and rational and formal ability, and the ability to conceptualize, and from the social consequences of learning logic and reasoning to speak, learning to speak properly, principled, attractive and thoughtful, and reinforcement of spiritual and everyday speech and the like. The results of conventional language analysis show that thinking education is mostly metaphorical and metaphorical, and the choice of different metaphors can have different educational outcomes. The use of conceptual metaphors in teaching thinking is effective in facilitating learning and learning, and teachers can, for better thinking, use students to direct their thoughts, ideas and phenomena, both metaphors, and that learners create metaphors to improve their learning and to creativity in their thinking. Teachers and educators should, in the process of teaching teaching, while working with children, follow the offending and gradual stages. At the end of the article, a typical model for the teaching of creative thinking based on conceptual metaphor was presented.

Abstract
The aim of this study was to investigate the effectiveness of cognitive rehabilitation, on improving the executive functions of selective attention, inhibitory control and working mwmory in elderly people with mild cognitive impairment. This experimental study was a Single Subject of type A-B, which 6 elderly (4 women and 2 men) with an average age of 62 years old were selected via purposeful convenience sampling and randomly assigned into two groups of control (n=3) and experimental (n=3). The evaluation of selective attention and inhibitory control was done using Stroop, Go/NO Go and N-back tests, and the "ARAM" rehabilitation program was presented in 10 one-hour personal sessions for each experimental group subjective. All subjective in both groups was evaluated 6 times (before, during, just after and 2 months following the intervention) and also control group were evaluated simultaneously without receiving any interventions. Using visual analysis, collected data revealed that the scores of both tests of executive functions in experimental group, were steadily increased all through intervention, while the control group scores’ did not make significant changes. Also, two-month follow-up evaluations showed a stable improvement in executive functions of the experimental group. Therefore, it can be concluded that cognitive rehabilitation based on ARAM program has improved the functions of selective attention, inhibitory control and working memory in elderly with mild cognitive impairment. As there are many documentaries suggesting possibility of leading mild cognitive impairment to more serious cognitive disabilities such as Alzheimer’s disease, such findings can confirm possibility of improving cognitive functions of elderly people with mild cognitive impairment with, with lower therapeutic costs applying the help of technology

Abstract
Recently, research has been conducted on the use of social networks as a new platform for identifying people with mental disorders. In addition, because of the complexity of diagnosing psychological diseases using conventional methods, the use of machine learning for identifying theses psychological diseases is increasing. The goal of this article was to systematically review the research conducted using social media data for predicting and diagnosing psychological disorders with the help of machine learning. Based on systematic review on the Prisma method, the aim of this article was achieved through searching the main keywords of diagnosis and the prediction of mental disorders combined with machine learning and social media data without considering the dates of their publications. Depression had the highest frequency among the final 20 selected articles with a predictive power of 42% and 87%, the lowest and the highest respectively. On the other hand, only 30% of studies used questionnaires for gathering data on social media and the most common approach for data collection was public posts on social media by the use of regular expressions. Twitter has also been used as the largest source of data collection in these sorts of studies. It seems that computational psychology based on machine learning methods could help to identify disorders at an appropriate time and select more effective treatments for mental disorders among the users of social media.

Abstract
Emotion Recognition is the main component of social cognition. The failure in emotion recognition can jeopardize the survival of the human in the environment. Emotion recognition has various pattern in different cultures and nationalities. Some of the emotions would recognize as strong or weak. Also, there is diversity in emotion recognition pattern in some psychological disorders and neurological damages. Finding the Iranian emotion recognition pattern with a valid neuro-psychological test is the main purpose of this study. This is a descriptive-analytical study. Participants with the age of 24 to 40 years were initially tested in computer intelligence and progressive matrices of Raven-2 Then, for 88 subjects who had obtained a normal score in the RAVEN-2 test, the excitement recognition subtest was taken from the Cambridge Neuro-Psychological test automated battery (CANTAB). The correct response of participants to each of the six emotions used for analysis. The average percentage of correct responses to each of the six emotions has been analysis by SPSS statistical software. The normal distribution and spherical condition exist among the accumulated data. The maximum rate of correct responses was 75.83% related to happy emotion, sad 70.00%, Surprise 68.48%, disgust 47.84%, angry 42.54%, and fear 38.26%. Iranians recognized happy emotions better than the other emotions and fear was the lees recognized emotion. The finding of this study can affect the evaluation of cognitive elements in the particular society like Iran and can identify the most cognitive abilities and inabilities in people. The result of this research deduces striking findings that can lead the evaluation of cognitive, social people of Iran.

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
| The effectiveness of different educational methods in learning different types of motor skills has been considered. However, comparisons of these methods in regulated team sports games have been less studied. Therefore, the aim of the present study was to compare the three educational methods of imagery, observation, and execution of in-field pattern on the performance of regulated games in skilled basketball players.15 players working in the country's Super League and Premier League competitions participated in this study with available access. The players were divided into 3 teams of 5 players according to the position of the game and were subjected to one of three training conditions in each stage based on random classification; So that each team performed all three methods randomly in each stage. Each condition included 1 practice session and a written and practical test session (after 24 hours). The players observed each tactic 3 times in the observation conditions; In terms of imagery, 3 trials were made for each tactic, and the execution conditions included 3 slow execution of tactics inside the field. The results of mixed analysis of variance 3 (training method) in 2 (written and practical test) showed that the execution method compared to observation and imagery causes better performance in regulated games (P <0.05); Also in the written test, the observation method scored higher than the imagery (P <0.05). Therefore, it seems that the field execution method for teaching team tactics in skilled players, has a greater advantage than the observation and imagery method, but the mental imagery is also more effective in acquiring knowledge of team tactics than observation. |

Abstract
| Making risky decisions in adolescents has become a major public health concern and understanding the correlations affecting this process makes it possible to implement prevention plans. Therefore, the present study was conducted to investigate the effect of positive and negative mood induction on risky decision-making by moderating high behavioral brain systems. In order to meet this aim, 327 adolescents aged 18-13 years in Isfahan were randomly selected and screened through the Behavioral Brain Systems Questionnaire (BAS / BIS). Based on the standard score, two groups of 24 participants including high BAS and BIS were selected. The members of each group were randomly divided into two equal subgroups, we induced positive mood in the first subgroup and negative mood in the second subgroup using Pieces of emotional movies. Participants completed the Balloon Risk Test (BART) and the Positive and Negative Emotion Scale (PANAS) before and after mood induction. Results of data analysis by univariate factor covariance analysis showed that there is a significant difference between inducing positive and negative mood on risky decision making (p≤ 0/05) and positive mood leads to increased risky decisions, The findings also showed that behavioral brain systems as biological personality traits significantly moderate the effect of mood induction on risky decision making (p≤ 0/05). This means that adolescents with a high behavioral activation system have more hyperactivity when faced with positive moods and they are more at risk than people with behavioral inhibition systems while adolescents with behavioral inhibition systems, on the other hand, are more sensitive to negative moods and signs of punishment and they are more cautious. |
