Connected and Isolated Victims of Relational Aggression: Associations with Peer Group Status and Differences between Girls and Boys

Some adolescents who are relationally victimized by gossip and ostracism have limited close connections to a peer or friendship group, but victimization also can be group-based, occurring between or within friendship groups. The purpose of this study was to test gender differences in these two forms of victimization, referred to as isolated and connected victimization, and to test associations of each form with peer status (social prominence and preference within the peer group) and aggressive behavior. We expected that associations between victimization, especially connected victimization, peer status and aggressive behavior would differ for boys and girls. Australian students (N = 335, M _age = 12.5 years) self-reported victimization, and nominated peers who were victimized, accepted, rejected, socially prominent, and unpopular. Connected and isolated forms of victimization were correlated, but differences were found in their correlations with other measures and by gender. Especially when reported by peers, adolescents higher in connected victimization were also higher in both aggression and social prominence (i.e., they were more popular and considered leaders); yet, they were also more disliked (rejected). In contrast to connected victimization, isolated victimization was associated with negative peer status only, and weakly and inconsistently associated with aggression. Finally, gender moderation was found, which showed a pattern of aggression, prominence and dislike among adolescent females who were connected victims, but this pattern was not nearly as pronounced in their male counterparts.     

Humean dispositionalism

Humean metaphysics is characterized by a rejection of necessary connections between distinct existences. Dispositionalists claim that there are basic causal powers. The existence of such properties is widely held to be incompatible with the Humean rejection of necessary connections. In this paper I present a novel theory of causal powers that vindicates the dispositionalist claim that causal powers are basic, without embracing brute necessary connections. The key assumptions of the theory are that there are natural types of causal processes, and that manifestations of powers are identified with certain kinds of causal processes. From these assumptions, the modal features of powers are explained in terms of internal relations between powers themselves and the process-types in which powers are manifested.     

How can you resist? Executive control helps romantically involved individuals to stay faithful

In the present research, we examined why some people have more difficulty than others in staying faithful to their romantic partners. Three studies supported our main prediction that executive control is associated with romantically involved individuals' ability to stay faithful. Study 1 showed that participants with a higher level of executive control reported less difficulty in staying faithful to their partners than did those with lower levels of executive control. In Study 2, romantically involved male participants were placed in a waiting room together with an attractive female confederate. Results showed that participants with a higher level of executive control showed less flirting behavior with the confederate than did those with lower levels of executive control. Study 3 demonstrated that a higher level of executive control was related to a lower expressed desire to meet an attractive other, but only for romantically involved participants. Together, these studies showed that executive control helps romantically involved individuals to deal with the lure of attractive alternatives.     

The role of reversal frequency in learning noisy second order conditional sequences

The hallmark of implicit learning is that complex knowledge can be acquired unconsciously. The second order conditionals (SOCs) of Reed and Johnson (1994) were developed to be complex, and they are popular materials for implicit learning research. Recently, it was demonstrated that in a sequence made noisy (by combining two SOCs), shared features of the SOCs may be learned explicitly (Fu, Fu, & Dienes, 2008). What are these shared features? We hypothesized that low reversal frequency may play a significant role. We have varied reversal frequency, and discovered that reversal frequency affected response times, inclusion exclusion behavior, and recognition ratings. Not only does it appear to be important to distinguish implicit and explicit knowledge, but also to distinguish what the knowledge is of.
