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 failures of memory function in post-traumatic stress disorder and its relationship with severity of symptoms need to take new approaches to improve the memory performance in patients. The aim of this study was to investigate the Effectiveness of emotional working memory Training on improvement memory in adolescents with Post- Traumatic Stress Disorder (PTSD). For this purpose, 4 adolescents (M: 2 F: 2) were selected available sampling by using 2 instruments (SCID-I) & (IES-R) The selected people– one by one were under emotional working memory training during 20 sessions. All people were assessed during three stages (pre-training, post- training and 2 month follow up) by children' Wechsler Digit Span Test (direct and reverse). Data were analyzed using the indices for trend changes, slope and the visual inspection of the charts; recovery percent index and effect size were used to determine the clinical significance. The results showed that emotional working memory training lead to increase in ability of participants in memory from pretest to follow up who suffering from Post- Traumatic Stress Disorders. Regarding the current study, it can be said that emotional working memory training is an appropriate choice for increase in memory in adolescents suffering from Post- Traumatic Stress Disorder

Abstract

the present study aimed to the comparison of the intolerance of uncertainty (IU) and short-term memory capacity in patients with obsessive-compulsive disorder and normal individuals. a total of 30 patients (16 female, 14 male) with obsessive-compulsive were selected using convenience sampling from the psychiatric clinics and centers of Tabriz were matched with 30 patients (16 females and 14 males) of normal individuals by demographic information, and all of them were assessed through Baher & Dougas’s intolerance of uncertainty scale and the Wechsler Digit span test subscales .Data were analyzed by multivariate analysis of variance (MANOVA) and as well as SPSS version 19. The results showed that there is a significant difference between the two groups in terms of IU (P<0/01) and the difference in patients with OCD is more than normal individuals. Also, there is a significant difference in terms of the short-term memory capacity (P<0/01) and the difference in normal individuals is more than patients with OCD . So it can be concluded that patients with OCD have less ability to tolerate uncertainty than normal people and short-term memory capacity in these patients is lower than normal people. Therefore, intolerance of uncertainty and low working memory capacity are two factors that may affect OCD symptoms and therefore exacerbate and perpetuate the disorder.

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.
