The aim of this research was to compare the effectiveness of MCT and Neurofeedback on metacognitive believes and symptoms of SAD. This research was a single subject study with volunteer sampling method. 7 students from Ferdowsi and Farhangian universities with diagnosis of SAD have been matched and assigned into one of the three groups (control, MCT and Neurofeedback).DSM-IV structured interview,Conner's Social Phobia Inventory, Watson and Friend's social anxiety questionnair, metacognition questionnair have been used before and after intervention and in 45 days follow-up.  Conner's Inventory also had been answered 2 times within the treatment. 8 session per week for MCT and 16 sessions 3 times each week for neurofeedback has been performed. Percent recovery is used for data analysis.  Results showed MCT and neurofeedback were effective in treating SAD with different range of percent recovery in each one of the subjects. But the mean of percent recoveries weren't different between the two interventions. Although metacognitive believes changed more in MCT. Percent recovery has improved in the follow up.  In general, MCT and Neurofeedback are both effective in reducing SAD but MCT was more effective in milder SAD and Neurofeedback was more effective in more severe SAD than MCT.

The purpose of this study is presentation the structural model of executive functions and extramarital relationship with mediating role of self­­­-control. The 210 samples were selected by convenience sampling. In experimental situation, for assessing executive function participants did computerized exams include: Stroop, Wisconsin, Go No Go and N- Back and completed self-control questionnaire of Tangney and attitudes toward infidelity scale of Whatley.  Data was analyzed through regression, structural equation modeling. Model has a suitable fit. Results shows that executive functions includes inhibition(-0/13), task switching(-0/13) ,working memory(-0/16)  and self-control(-0/10)had direct effect on extra marital relationship. Executive functions includes inhibition(-0/23), task switching(-0/11) ,working memory(-0/27) had indirect effect on extra marital relationship with mediation of self-control.

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.
