Cost-Benefit Analysis Mediation of the Relationship Between Sensation Seeking and Risk Behavior

Risk behavior during adolescence results in substantial morbidity and mortality. Sensation seeking consistently relates to engagement in risk behavior, but the psychological mediators of this relationship remain unclear. The current study demonstrates that adolescents’ judgments of the costs versus benefits of risk behavior were a significant mediator of this relationship. Participants were 406 racially and ethnically diverse adolescents ages 12-17 (M = 14.5, SD = 1.7; 48.3% female) who participated in a larger multi-site investigation of personality and neurocognitive predictors of risk behavior. Data were collected via self-report in a single laboratory session. Mediation of the relationship of sensation seeking to risk behavior was tested using structural equation modeling. Results indicated that higher levels of sensation seeking predicted weighing the benefits of risk behavior higher than its costs, which in turn predicted higher levels of risk behavior. Implications of these findings for understanding mechanisms underlying adolescents’ risk behavior and directions for future research are discussed.     

Exploratory decisions of Trinidadian guppies when uncertain about predation risk

Eye contact elicits bodily self-awareness in human adults

Eye contact is a typical human behaviour known to impact concurrent or subsequent cognitive processing. In particular, it has been suggested that eye contact induces self-awareness, though this has never been formally proven. Here, we show that the perception of a face with a direct gaze (that establishes eye contact), as compared to either a face with averted gaze or a mere fixation cross, led adult participants to rate more accurately the intensity of their physiological reactions induced by emotional pictures. Our data support the view that bodily self-awareness becomes more acute when one is subjected to another’s gaze. Importantly, this effect was not related to a particular arousal state induced by eye contact perception. Rejecting the arousal hypothesis, we suggest that eye contact elicits a self-awareness process by enhancing self-focused attention in humans. We further discuss the implications of this proposal.     

Wired for Society: Cognizing Pathways to Society and Culture

While cognitive scientists increase their tentative incursions in the social domains traditionally reserved for social scientists, most sociologists and anthropologists keep decrying those attempts as reductionist or, at least, irrelevant. In this paper, we argue that collaboration between social and cognitive sciences is necessary to understand the impact of the social environment on the shaping of our mind. More specifically, we dwell on the cognitive strategies and early-developing deontic expectations, termed naïve sociology, which enable well-adapted individuals to constitute, maintain and understand basic social relationships. In order to specify the way in which the demanding character of typical social relationships can be recognized in situ, we introduce the concept of “deontic affordances”. Finally, we shed light on the continuum that might relate a primitive naïve sociology, dedicated to the processing of invariant properties of the social life and a mature naïve sociology, necessary for dealing with the variable properties of cultural forms of life.     

L’avis du CCNE no 126 (15 juin 2017) sur les demandes sociétales de recours à l’assistance médicale à la procréation : un pas en avant et deux en arrière…

On June 15, 2017, the National Consultative Ethics Committee released an opinion in favour of the extension of medically assisted procreation (MAP) to lesbian couples and single women. This opinion recommends a reversal of the medical model, which serves as the starting point for the regulatory framework concerning MAP, and expresses its support to social and family evolutions. Nonetheless this liberal and progressive stand could be a mere smokescreen, if it does not result in any meaningful implementation due to practical hindrances; moreover, this seemingly progressive stand could be questioned in view of the conservative position expressed on the issues of surrogacy and oocyte self-preservation by the committee in the same opinion.     

Around the world,adolescence is a time of heightened sensation seeking and immature self‐regulation

The dual systems model of adolescent risk‐taking portrays the period as one characterized by a combination of heightened sensation seeking and still‐maturing self‐regulation, but most tests of this model have been conducted in the United States or Western Europe. In the present study, these propositions are tested in an international sample of more than 5000 individuals between ages 10 and 30 years from 11 countries in Africa, Asia, Europe and the Americas, using a multi‐method test battery that includes both self‐report and performance‐based measures of both constructs. Consistent with the dual systems model, sensation seeking increased between preadolescence and late adolescence, peaked at age 19, and declined thereafter, whereas self‐regulation increased steadily from preadolescence into young adulthood, reaching a plateau between ages 23 and 26. Although there were some variations in the magnitude of the observed age trends, the developmental patterns were largely similar across countries.     

Psychometric Properties of the Multidimensional Perfectionism Scale of Hewitt in a Dutch-Speaking Sample: Associations With the Big Five Personality Traits

We administered the Dutch Multidimensional Perfectionism Scale of Hewitt and Flett (1991, 2004) in a large student sample (N = 959) and performed a confirmatory factor analysis to test the factorial structure proposed by the original authors. The existence of a method factor referring to the negatively keyed items in the questionnaire was investigated by including it in the tested models. Next, we investigated how the 3 perfectionism dimensions are associated with the Five-factor model (FFM) of personality. The 3-factor structure originally observed by the authors was confirmed, at least when a method factor that refers to the negatively keyed items was included in the model. Self-oriented and socially prescribed perfectionism were both distinguished by low extraversion and low emotional stability. Self-oriented perfectionism's positive relationship with both conscientiousness and openness to experience differentiated the 2 perfectionism dimensions from each other. Other-oriented perfectionism was not well-characterized by the Big Five personality traits.
