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.

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.

This study was conducted to investigate the effectiveness of motivational interviewing in reducing the of Substance Users’ impulsivity who were under the Methadone Treatment. In a semi-experimental study, 40 methadone users of one of the addiction treatment centers in Yazd city were selected through availability sampling method and were then divided into two experimental and control group of twenty. In both groups two variables, age and economic satisfaction, were under control. In this research Barrat Impulsivity Scale was used to obtain the data. The experimental group underwent seven 90 minute sessions of motivational interviewing. Following the intervention, the two groups completed the above-mentioned scale as the post test. The post test revealed that motivational interviewing had an effect in reducing cognitive, motor impulsivity and non-planning in the subjects of the experimental group. Results of the study showed that motivational interviewing could significantly decrease cognitive, motor impulsivity and non-planning in experimental group in comparison to the control group.

The aim of this study was to investigate the prevalence of bullying among students and its relationship to the quality of family environment, impulsivity, depression, beliefs supportiveofaggressive behavior, and attitude towards school. The sample consisted of 344 secondary school students (205 girls and 139 boys) in Kermanshah who were selected by multistage cluster sampling method. They completed Olweus Bully/victim Questionnaire, University of Texas Depression scale, Impulsivity scale(Bosworth, 1999), Beliefs supportive of Violence (Dahlberg et al., 1998), Psychological sense of School membership scale (Goodenow, 1993), and family climate scale(Holman et al., 1994). Data was analyzed by descriptive analysis procedures and stepwise regression analysis. The results showed that different forms of bullying behaviors prevalence are 13/7 to 52/1 percent for boys, and 10/2 to 64.6 percent for girls. The most reported bullying behaviors for both of groups were name calling and teasing in hurtful way, and the least reported bullying behaviors were taking money or other thing away and damaging them. Results showed that among girls, among all studied variables have significant correlations with bullying behavior, but among boys just three variables (the quality of family climate, depression, and impulsivity) were significantly correlated with bullying behavior. Stepwise regression analysis also showed that for girls, the three variables Quality family atmosphere, a sense of belonging to school and attitudes toward violence significantly predict bullying, but for boys, only impulsivity was significant predictor.. Finally, the implications of findings are discussed.

Abstract

​​The aim of this study was to compare the effectiveness of Floortime method and Fernald multisensory method on impulsivity, mobility and concentration of hyperactive children aged 7 to 9 years. The research method was quasi-experimental with a pre-test post-test design. The statistical population consists of all hyperactive children aged 7 to 9 years in Salmas city in 1402. Using purposive sampling, 36 children were randomly divided into three groups (two experimental groups and a control group). The research measurement tool is the Conners Parental Hyperactivity Questionnaire. The data obtained from the two stages of pre-test and post-test were analyzed using the statistical method of analysis of covariance and Bonferroni post hoc test to compare the effect of the two treatments.

 

​​ The result showed that Floortime method and Fernald multisensory method have a positive and significant effect on mobility, impulsivity and concentration of hyperactive children and the effect of both Floortime method and Fernald multisensory method on mobility, impulsivity and concentration of hyperactive children is not different.
