Abstract
Recently, the study of cognitive processes in impulsive individuals has attracted the researchers’ attention. Considering impulsivity as a multidimensional construct, this study was performed to compare cognitive processing speed in 80 female college students who, on the basis of their scores on UPPS Impulsivity Scale (Whiteside & Lynam, 2001), were divided into four groups (n=20 for each) which were dominant in one of the impulsivity components (i.e. Urgency, Lack of Premeditation, Lack of Perseverance, Sensation seeking). Reaction time task was administered on all participants in two positive and negative mood contexts (which was induced by music). Results revealed a significant difference between the functioning of Urgency group and two other groups (Lack of Premeditation & Lack of Perseverance) in negative mood context. There were no significant differences between four groups’ functioning in positive mood context. The role of impulsivity dimensions and mood context on cognitive processing speed was discussed. In general the findings of present research emphasize the multidimensional concept of impulsivity & provide new guides to study lateralized cognitive processes according to personality constructs.

Abstract
The purpose of the present study is to investigate the metacognitive processes regard to the dimensions of anxiety and impulsivity. First, the sample of the study, 600 female students of Tarbiat Modares University, completed the Revised Eysenck Personality Questionnaire. Then, based on the subjects’ score in lie scale and their extreme scores in extraversion and neuroticism dimensions, 4 groups (15 subjects in each group) consisting of high anxiety (Anx+), low anxiety (Anx-), high impulsivity (Imp+) and low impulsivity (Imp-) subjects were selected, and completed Stroop and Wisconsin tests. The results indicated that the quality of metacognitive process and the executive functions similar to it were better in Anx- group in comparison to Anx+ group and in Imp- group in comparison to Imp+ group. Generally speaking, the results of this study highlight the effect of anxiety and impulsivity on metacognitive processes.

Abstract
The present study investigated the role of cognitive control and positive memory characteristics with special attention to the mediating roles of cognitive process and cognitive fatigue in flood-stricken victims. A sample of 280 participants were selected from flood-stricken areas including Gonbad, Gomishan and Aghghala. Data were collected using PCL-5, CPOTS, MEQ_SF, Mental Fatigue Scale, WAIS-IV, Stroop Test and Wisconsin Card Sorting. The data were then analyzed using SPSS and Smart PLS-3 softwares. The findings indicated no direct link between cognitive process and PTSD symptoms. However, cognitive process played a full mediating role in the relationship between cognitive control and PTSD symptoms and a partial mediating role in the relationship between positive memory characteristics and PTSD symptoms. The findings also revealed cognitive fatigue played a partial mediating role in the relationship between both cognitive contol and PTSD symptoms and positive memory characteristics and PTSD symptoms. The findings further showed the purposed model to investigate the relationships between the variables enjoyed a good fit. These findings can be the first step in identifying the PTSD symptoms of people who have been through flood trauma and can help us design evidence-based educational and rehabilitative programs to reduce psychocognitive pains of flood victims
