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.
3421 psychology of human behavior The Effectiveness of the Short-Term Executive Plus Intervention on Problem Solving, Emotion Regulation and Selective attention in Traumatic Brain Injury Patients Nasr Abadi Samira e Mousavi Nasab S. M. Hossein f Askari Zadeh Ghasem g Shahba Mohsen h e Shahid Bahonar University of Kerman f Shahid Bahonar University of Kerman g Shahid Bahonar University of Kerman h Kerman University of Medical Sciences 1 10 2021 9 3 16 26 01 05 2021 02 10 2021 Executive dysfunction is a hallmark of traumatic brain injury (TBI) and is associated with significant complications. Deficiency in problem-solving, emotion regulation, and attention is one of the most common phenomena after brain injury. This study aimed to evaluate the effectiveness of short-term intervention of dual executive function on problem-solving, emotion regulation, and selective attention in patients with traumatic brain injury. This quasi-experimental design used pre-test and post-test with a control group. Twenty subjects with brain injury were selected with the Purposive sampling method. They were randomly entered into two experimental and control groups (10 in the experimental group and 10 in the control group). After performing the pre-test, the experimental group received the short-term intervention and double executive function in 8 sessions of 90 minutes, while the control group did not receive any intervention. The assessment was performed in two stages of pre-test-post-test using a set of software tests of the Tower of London, Stroop and John and Gross (2003) Emotion Regulation Questionnaire. Analysis of covariance was used to analyze the data. The results showed a significant difference in the mean scores between the experimental group and the control group in all variables after the test. Therefore, it can be concluded that short-term intervention of dual executive function has a significant effect on improving attention, emotion regulation, and problem-solving in people with traumatic brain injury. 3426 Cognitive Sciences - Cognitive Psychology The Comparison of Quantitative Electroencephalography of Neural Connections between Children aged 6 to 13 years with Autism Spectrum Disorder and Typically Developing Children Azhdarloo Ahmad i Tabiee Maryam j Azhdarloo Mohammad k i Islamic Azad University of FiroozAbad Branch j Shiraz University k Islamic Azad University of Marvdasht Branch 1 10 2021 9 3 27 40 13 05 2021 26 09 2021 Recent neuroimaging studies have shown that main symptoms of Autism Spectrum Disorder (ASD) such as deficits in social communication, speech and repetitive behaviors are associated with abnormalities in neural connectivity. The abnormalities in neural connectivity have been studied by several methods. Among these methods, electroencephalography is an efficient and a non-invasive tool that records brain electrical activity and helps us to gain information about brain neural connectivity and cognitive characters. Therefore, the purpose of this study was to analyze electroencephalogram resting state data to compare brain connectivity (coherence) patterns between children with ASD and typically developing children. The method of this study was descriptive-analytical. The population of the study consisted of all children with ASD (aged 6-13) referred to psychologists in Mehraz Andisheh Clinic in Shiraz. Fifteen children with ASD (boys = 11 and girls = 4) were selected via purposeful sampling method. Moreover, a group of fifteen typically developing children who were matched based on chronological age and gender were recruited. Quantitative Electroencephalography data analyses showed a significant difference between the two groups and indicating hyper connectivity in most frequency bands among children with ASD. Therefore, quantitative electroencephalography patterns of children with ASD indicated an increase in the levels of coherence in delta (p < .05) and theta (p < .05) powers in the prefrontal region, theta (p < .05) and alpha (p < .05) waves in the central region, in theta (p < .001), alpha (p < .001) and beta (p < .001) waves in the occipital region, in addition to delta (p < .001), theta (p < .001) and alpha (p < .001) waves in the temporal region. The findings demonstrated abnormalities in brain connectivity (coherence) patterns of children with ASD which is supported by cortical connectivity theory. Consequently, these findings (hyper connectivity patterns) can be considered as a useful marker to better diagnose ASD. Moreover, changing these patterns may have a positive impact on the treatment of individuals with ASD. 3434 psychology of human behavior The Effectiveness of Training Metacognitive Beliefs and State on Working Memory of Elementary School Students Asadollahi Parisa l Salarifar Mohammad Hosein m Talebzadah Shoshtari Laila n l University of Birjand m University of Birjand n University of Birjand 1 10 2021 9 3 41 53 30 05 2021 29 09 2021 The purpose of this study was to investigate the effectiveness of training metacognitive beliefs and state on working memory of elementary school students.

Data were analyzed using Mann Whitney U, Friedman and Wilcoxon tests. The findings indicated a significant difference between the experimental group and the control group. Furthermore, the experimental group showed higher levels of mean in working memory scores compared to the control group. The results of the follow-up test suggested the lasting effect of the training. According to the results of the present study, it can be concluded that training metacognitive beliefs and state might enhances students’ working memory. 3437 Medical Engineering - Bioelectric Classification of EEG Signals in Two Levels of Normal and Anxious Using Nonlinear Features Daneshmand-Bahman Faezeh o Goshvarpour Ateke p o Department of Biomedical Engineering, Imam Reza International University, Mashhad, Razavi Khorasan, Iran. p Department of Biomedical Engineering, Imam Reza International University, Mashhad, Razavi Khorasan, Iran. 1 10 2021 9 3 54 69 03 06 2021 29 09 2021 Anxiety is a natural reaction of humans to stress that occurs in the face of various factors. Anxiety is considered as a mental illness if it is excessive and uncontrollable in the form of fear and anxiety. Today, clinicians use certain criteria to diagnose anxiety disorders. This analytical-observational study was aimed at automatically classifying the two levels of anxious and normal by analyzing electroencephalogram signals. In this paper, the DASPS database was used, which contains a 14-channel electroencephalogram of 23 people (13 females and 10 males, mean age 30 years) during anxiety. Anxiety was presented in the form of flooding as actual exposure to the feared stimulus. Based on the results of the Self-Assessment Manikin, data were divided into two groups: (1) normal and low anxiety and (2) moderate and high anxiety. Approximate entropy, fractal dimension, and Lyapunov exponents were extracted from all channels as nonlinear properties. Maximum relevance and minimum redundancy were used to select the best feature to apply to the multilayer perceptron network. To evaluate the performance of the algorithm, different network structures were examined in terms of the number of features and neurons as well as different feature dimensions. Maximum accuracy, precision, f1-score, and sensitivity in 20 repetitions in all cases is equal to 100, and with an increasing number of neurons, the average accuracy increases. The best results were obtained for 5 features and 15 neurons, where the mean accuracy, precision, f1-score, and sensitivity for it were 80%, 92.75%, 84.15%, and 80.58%, respectively. The results of this paper indicated the capability of the proposed algorithm to distinguish anxious people from normal ones. 3446 psychology of human behavior The Effect of Brain Training on Suppression of Theta/Alpha Ratio and Working Memory of 8 to 12 year old Children with Dyslexia and Dysgraphia Amiri Mohsen karami Jahangir Momeni Khodamorad Razi University Razi University Razi University 1 10 2021 9 3 70 88 15 06 2021 02 10 2021 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. 3507 Clinical Psychology Verbal and Visual Proactive Interference in Post-Traumatic Stress Disorder Daneshvar Somayeh Taghavi Mohammad Reza Shiraz University Shiraz University 1 10 2021 9 3 1 26 23 10 2021 21 06 2022 Objective: Working memory executive deficits have a role in maintaining Post-Traumatic Stress Disorder (PTSD) symptoms including flashbacks and reexperiencing. Accordingly, the aim of the present study was to compare the visual and verbal Proactive Interference in trauma-exposed individuals with and without PTSD.  Method: In this retrospective study, we recruited subjects through the purposive sampling method. We compared 30 survivors of road traffic accidents with PTSD with 30 trauma-exposed individuals without PTSD in terms of visual and verbal Proactive Interference. Measuring tools included the Post-Traumatic Stress Disorder semi-structured Interview for DSM-V, the Beck Depression Inventory-II and the Recent Probes Task. Data were analyzed using mixed repeated-measures analysis of variance (ANOVA) in SPSS-21 software. Results: Subjects of the PTSD group reported higher levels of visual and verbal Proactive Interference than the control group. Moreover, patients with PTSD indicated higher deficiencies in visual working memory than verbal working memory. Conclusion: Patients with PTSD show deficiencies in controlling proactive interference that should be taken into consideration through their treatment procedure.   3653 psychology of human behavior Comparison of p300 in risk-seeker and risk-averse people during simple gambling task Sabouri Moghadam hasan Nazari Mohamad Ali Naghel Sedigheh Valessi Antonino KhosroAbadi Reza 1 10 2021 9 3 0 18 21 11 2022 26 02 2023 Risk preference, the degree of tendency to take risk, has a fundamental role at individual and social health and is divided to risk seeker and risk averse. Therefore, the study of neural corelates of risk preferences is essential at the field of psychology and psychiatry. The current study aimed to examine and compare an ERP component named P300 between subjects with different risk preferences. Method: 28 people placed in two groups of risk seeker and risk averse (14 each group). Subjects performed simple gambling task. ERP data were processed by MATLAB software and ERPlab. Repeated measurement ANOVA was used to analyze data. Results: analysis of behavioral data presented that risk seekers selected low risk option more than high risk, but there was no significant difference of reaction time between groups. ERP analysis showed a significant decrease of P300 amplitude in risk seekers compared to risk averse when selecting high risk option. This result shows the importance of the differences in dopaminergic and motivational pathways of risk seekers during reward processing compared to healthy and risk-averse groups. Based on this result, it may be possible to consider the P300 component as a suitable indicator in clinical evaluations.
