The aim of the current study was to investigate negative processing of implicit information relating to self by self-esteem implicit association test in depressed and non-depressed students.17 depressed students and 17 non-depressed students were selected according to a convenience sampling method. Beck depression inventory (BDI-II) and clinical interviews were employed to diagnose depressed individuals. The Beck anxiety inventory (BAI) was conducted to control of participant's anxiety. The data were analyzed using analysis of covariance (ANCOVA).Results revealed that depressed individuals had higher scores in Beck depression inventory (BDI-II) than non-depressed (p = 0.001). It is also a significant difference between depressed and non-depressed individuals (p = 0.003).According to the results of this study, it can be concluded that depressed studentshave lower implicit self-esteem scores than non-depressed, in self-esteem implicit association test (IAT).

The aim of this study was to evaluate the effectiveness of emotional working memory training on improving cognitive control of participants with high trait anxiety symptoms. This study was based on a quasi-experimental design pretest& posttest with active control group. 28 students from Ferdowsi University of Mashhad with high scores on trait anxiety, State-Trait Anxiety Inventory were voluntarily selected, according to available sampling. 14 people in both experimental and active control groups were matched and randomly assigned into two groups. To measure cognitive control color-word Stroop test was used. Persian Emotional Working Memory Training was used with the experimental group and Shape Matched Training Task was used with the active control group To analyze the results multivariate analysis of covariance was conducted The results showed a significant difference in cognitive control components (congruent reaction time, incongruent reaction time and interference score) between the two groups.

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 aim of this study was to investigate the Improvement cognitive inhibition of children with attention deficit / hyperactivity in the context of emotional working memory training. The 20 children with attention deficit / hyperactivity were selected available sampling and using diagnostic tools (SCID-I and SNAF-IV) and randomly assigned to two experimental and control groups. The experimental group were trained in emotional working memory for 15 sessions of 40-30 minutes during 15 days, while the control group did not receive such training. Both groups were tested in pre-test and post-test by classic Stroop test. The results of multivariate analysis of covariance showed that emotional working memory training has leads to Improvement cognitive inhibition in the experimental groups in comparison with the control group. Thus, it can be concluded that that emotional working memory training can as a viable option for improvement cognitive inhibition in children with attention deficit / hyperactivity disorder be regard to specialists and researchers

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.
