MULTIDIMENSIONAL SCALING OF GEOMETRICAL FIGURES

In two experiments with geometrical figures as stimuli, constructed in order to generate perceptual variation of roundness and height, four multidimensional scaling methods were compared, two metric and two nonmetric. The methods gave similar solutions. The fact that the solutions could be interpreted in accordance with expectations, points to the validity of the methods.     

Distributional typicality: a new approach to estimating noun and verb usage from large scale text corpora

This paper reports a new approach to estimating the extent to which words have predominant noun and verb usages which do not require human judgments about parts of speech. The Hyperspace Analog to Language model (HAL, Lund & Burgess, 1996) was used to computationally estimate noun vs verb usage based on the statistical regularities present in a large-scale electronic text corpus. This measure can be used to estimate the extent to which a given word occurs in typical noun or verb sentence contexts (i.e., its distributional typicality) in informal contemporary discourse.     

Maternal and paternal parenting styles associated with relational aggression in children and adolescents: A conceptual analysis and meta-analytic review

How does parenting affect relational aggression in children? The goal of the present series of meta-analyses based on 48 studies (28,097 children) was to analyze and integrate the findings on the associations between various types of parenting behaviors and relational aggression, and to identify potential substantive and methodological factors that may moderate these associations. To distinguish between different parenting strategies, experts sorted the parenting measures used in the studies into 10 groups. Results of a multiple correspondence analysis revealed four separate clusters: Positive parenting, psychologically controlling parenting, negative/harsh parenting, and uninvolved parenting. The meta-analyses demonstrated that more positive parenting was associated with less relational aggression (combined effect sizes r = −.06, p < .05, for mothers, r = −.08, p < .01, for fathers). More harsh parenting (combined effect sizes r = .11, p < .01, for mothers, r = .12, p < .01, for fathers) and more uninvolved parenting (combined effect sizes r = .07, p < .01, for mothers, absent for fathers) were associated with increased relational aggression. Paternal psychologically controlling parenting was positively related to relational aggression (r = .05, p < .01), whereas maternal psychologically controlling parenting was not (combined effect sizes r = .04, p = .09). The effect of several moderators is discussed. The findings of this study suggest that dimensions of positive and negative parenting behaviors of mothers and fathers are associated with children’s relational aggression and that these associations are – in case of fathers – contingent upon a number of sampling and procedural characteristics.     

A Longitudinal Study of Relational Aggression, Physical Aggression, and Children's Social–Psychological Adjustment

Although great strides have recently been made in our understanding of relational aggression and its consequences, one significant limitation has been the lack of prospective studies. The present research addressed this issue by identifying and assessing groups of relationally aggressive, physically aggressive, relationally plus physically aggressive (co-morbid), and nonaggressive children during their third grade year in elementary school and then reassessing them a year later, during fourth-grade (N = 224, 113 girls). Two aspects of social–psychological adjustment were assessed during both assessment periods including internalizing difficulties (i.e., withdrawal, depression/anxiety, and somatic complaints) and externalizing problems (i.e., aggressive behavior, delinquency). It was revealed that the strongest predictor of future social–psychological adjustment problems and increases in these problems from third to fourth was the combination of relational and physical aggression. Relational aggression also contributed unique information, relative to physical aggression, in the prediction of future maladjustment. Implications of these findings for future research and prevention efforts, particularly for aggressive girls, are discussed.

Forms of Aggression,Social-Psychological Adjustment,and Peer Victimization in a Japanese Sample: The Moderating Role of Positive and Negative Friendship Quality

The purpose of these studies was to examine the frequency and stability of relational and physical aggression and their associations with social-psychological adjustment or peer victimization, and how friendships are involved in the relations between forms of aggression and peer victimization in Japanese children. The sample consisted of 452 (Study 1) and 138 (Study 2) children who were in the fourth and fifth grades. Results of Study 1 demonstrated that relational aggression was uniquely and more strongly associated with internalizing adjustment problems than physical aggression. Moreover, Study 2 revealed that relational aggression and physical aggression were stable over a 6-month period and the stability of relational aggression was reinforced by negative friendships (i.e., high levels of exclusivity and friend victimization). Further, the association between relational aggression and relative increases in relational victimization was attenuated by positive friendships (i.e., high levels of intimacy, companionship, and friendship satisfaction). Interestingly, friendships were unrelated to physical aggression and its relation to physical victimization. The age and gender of the children in the two studies were also examined. Cultural and developmental processes involving forms of aggression, friendships, social-psychological adjustment, and peer victimization were discussed.     

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.
