Abstract
The purpose of this study was to investigate the relationship between the dimensions of Family communication patterns (conversation orientation and conformity orientation) and adolescents' Shyness. The sample the study included 367 students, 232 girls and 135 boys, who were first and second high school students in the first region of Tehran, and they were selected through multistage cluster sampling method. The subjects filled in the revised family communication patterns scale (koerner & Fitzpatrick, 2002) and Cheek and Buss Shyness scale (1981). Regression analysis was used to predict shyness by Dimensions of family communication patterns. Then, four kinds of families were extracted based on high and low scores on dimensions of family communication patterns and the adolescents’ shyness in these families was compared by using One-way ANOVA analysis. The results of regression analysis revealed that family conversation orientation had a negative and significant relationship with shyness and predicted it negatively and family conformity orientation had a positive and significant relationship with adolescents' shyness and predicted it positively. The results of the analysis of variance indicated a significant difference between these groups and showed that the children in consensual and pluralistic Families had less shyness than the children in protective and careless families. The findings of the present research showed that families with conversation orientation, who had free, comfortable and rich relationships as a need for joyful family life, raised children who are less shy in comparison with the children being raised in the families with conformity orientation

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
This study investigated the degree of cortical arousal of the forehead during working memory performance in personality dimension of anxiety. Based on Gray’s definition of personality dimension of anxiety, in a pseudo-empirical study a sample of female students (n=793) aged from 18 to 28 years old completed Eysenck Personality Questionnaire and Carver and White’s Approach/Avoidance scale. 15 subjects whose scores were simultaneously in the upper distribution of Neuroticism and lower distribution of Extraversion (N+E-) were selected as high trait anxiety group (Anx+), and low trait anxiety group (Anx-) consisted of 15 subjects with higher scores of Extraversion and lower scores of Neuroticism (N-E+). Then their EEG was taken in baseline mode and while performing working memory task. Total scores in 1-back working memory task were taken as the indicator of working memory performance and EEG alpha oscillation during 1-back task was taken as cortical arousal index. Data were analyzed using T-test for independent samples. Results revealed that high trait anxious subjects showed more arousability in their right and left cortex of forehead during working memory performance, while their performance in working memory tasks was impaired in comparison with low trait anxious group. These Results supported Processing Efficiency Theory, which means although high trait anxious individuals employed higher mental effort during executive functions, their processing efficiency was impaired.

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.
