The main aim of this study was to investigate the Overgenerality of Autobiographical Memory among the adolescent boys in Kermanshah,Iran . A   sample of 76 Kemanshahian adolescents   (25 non-depressed and 50 depressed adolescent boys,25 with substance abuse disorder and 25 without substance abuse disorder) were investigated. To evaluate autobiographical memory specificity, a standard AMT (Autobiographical Memory Test), developed by Williams and Broadbent (1986), was used. To analyze the data, the Mann-Whitney U test was used.  The results indicated that depressed adolescent boys without substance abuse disorder had high scores in Overgenerality of autobiographical memory than non-depressed group depressed adolescents with substance abuse disorder had high scores in Overgenerality of autobiographical memory than non-depressed group and depressed adolescents without substance abuse disorder had high scores in Over generality of autobiographical memory than depressed adolescents with substance abuse disorder.

The aim of the study was to investigate the effect of therapeutic touch and muscle relaxation on trait and state anxiety in Tarbiat Moallem University’s students, Tehran. Population of the study included all the students of this university in the academic year 2007-2008.A sample of 40students was selected through simple random sampling. Based on Spielberger state-trait anxiety inventory (STAI),the subjects were put into four groups of ten: Therapeutic touch group, muscle relaxation group, anxious control group and normal group control. In this study which was a quasi-experimental research, pretest-posttest, control group design was used. To analyze and to test the hypotheses of the study, Analysis of Variance (ANOVA) was used. The findings revealed that there was a significant difference between the experimental and control groups in terms of state and trait anxiety. Therefore, muscle relaxation can be used to decrease the anxiety, since the results of the study indicated that muscle relaxation method can have an effective role in decreasing state and trait anxiety.

The purpose of this study was to investigate the changes in implicit and explicit cognitive processes during and after different intensities of aerobic physical exercise based on Transient Hypofrontality Theory. 39 male subjects with an average level of physical activity (age: M = 20.97± 0.14 Vo2 max: M = 50.25± 6.92 ml/kg/min) were divided randomly to three groups of thirteen based on the intensity of aerobic physical exercise: high intensity group (first group), moderate intensity group (second group), and low intensity group (third group). Magnetic bike was used for aerobic physical activity and heart rate remote control was used to control the intensity of activity. Implicit cognitive process (Visual choice reaction time) and explicit cognitive process ( Stroop) tests were performed in four times: before and during the activity, 1 minutes and 15 minutes after the cessation of the activity. Results of the repeated measure ANOVA and inter-group factor showed that the effects of factors including time, group and interaction were significant on the implicit cognitive test.                                                                                                         As for the explicit cognitive test , the major effect of time, interaction and group was significant. Results of this study showed that transient hypofrontality occurred when the intensity of aerobic physical exercise was high.

The applications  of  electrical  stimulation of  the  brain , which include invasive and non-invasive methods , are now burgeoning in the fields of neuroscience. The aim of this study, was to investigate the effects of transcranial direct current stimulation on dorsolateral prefrontal cortex (DLPFC) in reducing the smoke craving and the rates of stress. Therefore, using random sampling and snowball method, in the population of smokers in the students of kharazmi university, we selected 20 subjects and assigned them in experimental and control group. The instrument used in this study, was the smoking urge questionnaire (SCQ) and stress subscale of depression, anxiety, stress scale (DASS). Analysis of covariance and t-test of diminished scores showed that there are significant differences between groups in rates of craving and stress in post-test stage (respectively, 0.035 & 0.000, p<0.05).in addition, the number of used cigarette reduced after interventions (0.029,p<0.05). Generally, tDCS had an effective role in reduction of smoke craving and stress in experimental group.
