Problem Gambling in Adolescence: An Analysis Conducted from the Actor’s Perspective

The objective of this study is, by using the general theory of rationality (GTR), to better understand the rationale underlying gambling behavior in adolescents considered to have gambling problems. The study explore gambling associated benefits, negative consequences of gambling, and the adolescents’ perceptions of the severity of their gambling behavior. The qualitative research is based on semi-structured interviews with 31 adolescents considered as having gambling problems. The analysis revealed that gambling behavior are based on a threefold rationality: instrumental, cognitive and axiological. The GTR allows to better understand why most of them do not consider to have gambling problems.     

Empirically distinguishing interpersonal styles within romantic relationships: What is helpful or harmful when having a goal for your romantic partner?

IntroductionRelationship research rooted in self-determination theory often focuses on autonomy support. However, rarely is this interpersonal style considered alongside other facets of relational behaviours such as directive support and control.ObjectiveThe present study aimed to distinguish the three styles by providing a tool that can simultaneously assess them.MethodA total sample of 710 French Canadians involved in a romantic relationship was used for factor extraction and test of dimensionality as well as reliability. Predictive validity was tested using multiple linear regressions with six outcomes: well-being, relationship quality, closeness, goal progress, cooperation and conflicts.ResultsResults suggested three distinct interpersonal styles, each of which showing a different pattern of prediction with the outcomes. Overall, autonomy support was associated with positive outcomes, whereas control was associated with negative outcomes. As for directive support, the global pattern was between the two others.ConclusionThe present research offers a scale which simultaneously assesses and distinguishes the autonomy-supportive, directive-supportive and controlling styles in a romantic relationship context using three items each. By examining the associations between these three interpersonal styles and various outcomes four months later, this study sheds light on helpful and harmful behaviours in relation to the goals people have for their romantic partner.     

Remaining or becoming secure: Parental sensitive support predicts attachment continuity from infancy to adolescence in a longitudinal adoption study

In a longitudinal study with 125 early adopted adolescents, we examined continuity of attachment from infancy to adolescence and the role of parental sensitive support in explaining continuity or discontinuity of attachment. Assessments of maternal sensitive support and infant attachment (Strange Situation Procedure) were completed when infants were 12 months old. When the children were 14 years old, we observed mothers' sensitive support during a conflict discussion. The adolescents' attachment representations were assessed with the Adult Attachment Interview. Mothers of secure adolescents showed significantly more sensitive support during conflicts than did mothers of insecure adolescents. Overall, no continuity of attachment from infancy to adolescence was found. However, maternal sensitive support in early childhood and adolescence predicted continuity of secure attachment from 1 to 14 years, whereas less maternal sensitive support in early childhood but more maternal sensitive support in adolescence predicted children's change from insecurity in infancy to security in adolescence. We conclude that both early and later parental sensitive support are important for continuity of attachment across the first 14 years of life.

Centre-embedded structures are a by-product of associative learning and working memory constraints: evidence from baboons (Papio Papio)

Influential theories have claimed that the ability for recursion forms the computational core of human language faculty distinguishing our communication system from that of other animals (Hauser, Chomsky, & Fitch, 2002). In the present study, we consider an alternative view on recursion by studying the contribution of associative and working memory processes. After an intensive paired-associate training with visual shapes, we observed that baboons spontaneously ordered their responses in keeping with a recursive, centre-embedded structure. This result suggests that the human ability for recursion might partly if not entirely originate from fundamental processing constraints already present in nonhuman primates and that the critical distinction between animal communication and human language should more likely be found in working memory capacities than in an ability to produce recursive structures per se.     

Perspective taking and opinions about forms of reparation for victims of historical harm

The authors investigated the effects of perspective taking on opinions about reparations for victims of historical harm. In two studies, they showed that when non-Indigenous Australians took an Indigenous Australian perspective, this increased perceived entitlement to, and decreased anger toward, monetary compensation. Moreover, perceived entitlement mediated the relationship between anger about monetary compensation and perspective taking. Study 2 demonstrated the mutual influence of emotions and perceived entitlement. In particular, self-image shame rather than group-based guilt or anger predicted support for reparation when an Indigenous Australian perspective was adopted. The results suggest that taking the perspective of people who have experienced harm from one's own group can bolster a commitment to positive social change in relation to a pressing social issue.     

Numerical and nonnumerical estimation in children with and without mathematical learning disabilities

There are currently multiple explanations for mathematical learning disabilities (MLD). The present study focused on those assuming that MLD are due to a basic numerical deficit affecting the ability to represent and to manipulate number magnitude ( Butterworth, 1999 , 2005 ; A. J. Wilson & Dehaene, 2007 ) and/or to access that number magnitude representation from numerical symbols ( Rousselle & No?l, 2007 ). The present study provides an original contribution to this issue by testing MLD children (carefully selected on the basis of preserved abilities in other domains) on numerical estimation tasks with contrasting symbolic (Arabic numerals) and nonsymbolic (collection of dots) numbers used as input or output. MLD children performed consistently less accurately than control children on all the estimation tasks. However, MLD children were even weaker when the task involved the mapping between symbolic and nonsymbolic numbers than when the task required a mapping between two nonsymbolic numerical formats. Moreover, in the estimation of nonsymbolic numerosities, MLD children relied more than control children on perceptual cues such as the cumulative area of the dots. Finally, the task requiring a mapping from a nonsymbolic format to a symbolic format was the best predictor of MLD. In order to explain these present results, as well as those reported in the literature, we propose that the impoverished number magnitude representation of MLD children may arise from an initial mapping deficit between number symbols and that magnitude representation.     

Impact of the 1998 football World Cup on suicide rates in France: results from the national death registry

Our objective was to determine whether the Fédération Internationale de Football Association (FIFA) World Cup in 1998 had a short-term impact on the number of suicides in France. Exhaustive individual daily data on suicides from 1979 to 2006 were obtained from the French epidemiological center on the medical causes of death (CepiDC-INSERM; France). These data were analyzed using the seasonal ARIMA model. The overall effect of the World Cup was tested together with potential specific impact on days following the French team games. Between 11th June and 11th July, a significant decline of 95 suicides was observed (-10.3%), this effect being the strongest among men and people aged between 30 and 44. A significant decrease was also observed for the days following French team games (-19.9%). Our results are in favor of an effect of nationwide sport events on suicidal behaviors and are consistent with other studies. Many of the theories explaining the relationship between sports and suicide are related to sense of belongingness and social integration, highlighting the importance of social link reinforcement in suicide prevention.
