The aim of this study was to investigate the efficacy of metacognitive therapy (MCT) on improvement of symptoms of major depression, cognitive attentional syndrome, and maladaptive copings in two patients with major depression. Case Description: In a single case experiment with multiple baseline design 2 women suffering from major depressive disorder (MDD) were treated with eighth weekly sessions of MCT and antidepressant medications. Instruments used in this research were included Beck depression inventory, major depressive disorder scale (MDD-S), metacognitive beliefs, metacognitions questionnaires, ruminative response style (RRS), and cognitive attentional syndrome (CAS) scale. Results: Data indicated that metacognitive treatment resulted in reduction of subject's scores in metacognitive scale and RRS scale in post-test and 2 months follow up. The CAS and MDD-S scores showed remarkable reduction. Conclusion: Metacognitive therapy as a new emerging approach appears to be an effective treatment approach for patients suffering from MDD. The effect of MCT can be due to decrease in rumination and/or positive and negative metacognitive beliefs.

Introduction: Previous studies investigating the role of emotion in working memory suggest that emotion plays an important role in working memory. The present research aimed at investigating the effectiveness of process emotion regulation training in visualspatial and verbal working memory. Methods: Therefore, 26 students of Kharazmi University (16 females and 10 males) were selected through volunteer sampling and underwent the of Process Emotion regulation strategies training. All individuals were evaluated during three stages of training (prior, meanwhile and subsequent to the training) using the Working Memory Index. Variance analysis with repeated measurement and Bonferroni post-hoc test were used in for analyzing the results. Results:The results indicated that Process Emotion regulation training increases the visual-spatial and verbal working memory capacities. Conclusions: With regards to the results of the present research, it could be concluded that emotion regulation might lead to information preservation and boost the verbal and visual-spatial capacity of working memory by the means of decreasing the impact of emotions influencing the deficit in working memory function.
