Adolescent Impulsivity: Findings From a Community Sample

Impulsivity is central to several psychopathological states in adolescence. However, there is little consensus concerning the definition of impulsivity and its core dimensions. In response to this lack of consensus, Whiteside and Lynam (2001, Pers. Individ. Differ. 30, 669–689) have developed the UPPS Impulsive Behavior Scale, which is able to distinguish 4 dimensions of impulsivity in adults: Urgency, lack of Premeditation, lack of Perseverance, and Sensation seeking. The question arises of whether these 4 dimensions also exist in adolescents and also of whether gender differences can be observed. A sample of teenagers (314 girls and 314 boys) completed a French version of the scale (Van der Linden et al., Eur. J. Psychol. Assess., 2005). Based on exploratory and confirmatory analyses, the 4-factor model is replicated in girls, boys, and the whole sample. Concerning gender differences, girls have a higher score for Urgency and boys a higher score for Sensation seeking. Overall, this study suggests that the UPPS is a promising tool for studying impulsivity in adolescence.

Reactions to Perceived Fairness: The Impact of Mortality Salience and Self-Esteem on Ratings of Negative Affect

In correspondence with terror management theory, the findings of two experiments show that reminders of death lead to stronger effects of perceived fairness on ratings of negative affect. Furthermore, in line with the theory's self-esteem mechanism, results of Experiment 1 suggest that state self-esteem may mediate this relationship between mortality salience and fairness. In further correspondence with the self-esteem mechanism, findings of Experiment 2 reveal that introducing an activity (after reminders of death and before the fairness manipulation) with which people can reaffirm positive conceptions of themselves leads people to react less strongly to variations in fairness than not introducing such a self-affirmation activity. These findings suggest that people react especially strongly to perceived fairness when they are in need for a boost in their self-esteem. Implications for the psychology of fairness are discussed.     

Explaining Ethnic Autonomy Regimes in Latin America

Through a systematic examination of nine cases, the author identifies factors that enabled indigenous movements in five Latin American countries to secure formal recognition of politico-territorial autonomy regimes. All nine cases occurred within the framework of a larger regime bargain—either (1) peace talks intended to end armed struggle when the regime faced a serious challenge to maintain political order or territorial control, or (2) a severe crisis of legitimacy and governability that forced political elites to renegotiate fundamental regime structures via the process of constitutional reform. In the five successful cases, changes in the political opportunity structure occurred that favored indigenous autonomy claimants. These changes were the opening of access to decision-making spheres and the emergence of an influential ally.

Social and emotional detachment in Dutch children

Characteristics associated with psychopathy were, along with the symptoms of aggressive and antisocial behaviour, rated by parents in a community sample of 2535 four-to-eighteen-year-old Dutch children in 2003. An analysis of principal components suggested two dimensions of psychopathic characteristics. The first dimension comprised egocentric characteristics and the second unemotional characteristics. Regression analyses further showed that antisocial behaviour could be predicted by egocentric characteristics, while aggressive behaviour could be predicted by the interaction of egocentric and unemotional characteristics. To avoid unnecessary stigmatisation of youngsters, it is proposed to label the egocentric dimension as the 'social detachment' factor and the unemotional dimension as the 'emotional detachment' factor.
