Abstract
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).

Abstract
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.

Abstract
Obesity is one of the most important problems which threatens the global health. Healthcare organizations spend a
large amount of money to predict and treat obesity every year. The most common treatment for obesity is
concentrated on shaping a new lifestyle with more exercise and healthy diet. But a multitude of dieters fail. In this study, the role of cognitive processing in dieters` success or fail was investigated. Participants were
successful (N= 42) and unsuccessful (N= 45) dieters between 18 and 40 years old. Attentional bias, positive
implicit association, and working memory capacity were measured by dot-probe task, a modified
version of implicit association test (IAT), and N-Back task. Results indicated that unsuccessful dieters showed
greater attentional bias to (d= 0.69) and more food preferences for (d= 1.06) high-calorie food pictures.
Nevertheless, there was no significant difference in implicit associations for high calorie food and in working memory capacity between the groups. These results were congruent with some previous studies and they were discussed based on dual-processing model.

Abstract
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.

Abstract
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.
