This study investigated attention bias, depression and anxiety in adolescents with Diabetes type 1.Population of the study included all 13 to 20 years old adolescents of the Iranian Diabetics Association. Of these diabetics, 25 subjects were selected as samples of the study and a group of 25 non-diabetic adolescents also participated in the study as the control group. The measurement tools were modified Stroop colour naming task, Spielberger State-Trait Anxiety Inventory and Beck Depression Inventory. When it came to analyzing the data, multivariate analysis of variance was used. The results indicated that the diabetic group had low time reaction in diabetes related words, neutral words, positive and negative words than the  control group furthermore, depression and anxiety scores of the selected diabetics were higher than control group

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.
