Body Image and Self‐Esteem Among Adolescent Girls: Testing the Influence of Sociocultural Factors

In Western cultures, girls' self‐esteem declines substantially during middle adolescence, with changes in body image proposed as a possible explanation. Body image develops in the context of sociocultural factors, such as unrealistic media images of female beauty. In a study of 136 U.K. girls aged 11–16, experimental exposure to either ultra‐thin or average‐size magazine models lowered body satisfaction and, consequently, self‐esteem. Self‐esteem was also lower among older than among younger girls. Structural equation modeling showed that this age trend was partially accounted for by a corresponding downward trend in body satisfaction; this, in turn, was fully accounted for by upward age trends in awareness and internalization of sociocultural attitudes toward appearance, and in social comparison with media models. Results support calls for early educational interventions to help girls to deconstruct advertising and media images.     

“I Wish to be Self-Reliant”: Aspiration for Self-Reliance,Need and Life Satisfaction,and Exit Dilemma of Welfare Recipients in Hong Kong

This qualitative study explores the welfare recipients’ experiences of and attitudes toward the welfare benefit system in Hong Kong. A sample of 19 welfare recipients from six main recipient groups was interviewed, some twice. This study finds that the recipients have strong aspirations to exit the welfare benefit system. The welfare application process is painful; they are strongly stigmatized; they do not have sufficient resources to meet many of their expected needs; and, after all, they have strong ethos for self-reliance. However, they remain in the benefit system. This study looks into this paradox and the challenges facing the welfare benefit system in Hong Kong in terms of providing ontological security on the one hand and promoting self-reliance on the other.     

Robustness and monotonicity properties of generalized correlation coefficients

A new class of generalized correlation coefficients that contains the Pearson and Kendall statistics as special cases was defined by Chinchilli et al. (2005) and applied to the estimation of correlations coefficients within the context of 2×2 cross-over designs for clinical trials. In this paper, we determine the infinitesimal robustness and local stability properties of these generalized correlation coefficients by deriving their corresponding influence functions. For cases in which the population distribution is a bivariate normal or a mixture of bivariate normal distributions we obtain explicit formulas, and establish monotonicity and sign-reverse rule properties of the generalized correlation coefficients.     

Young Infants Detect the Direction of Biological Motion in Point‐Light Displays

In the present study, we examined if young infants can extract information regarding the directionality of biological motion. We report that 6‐month‐old infants can differentiate leftward and rightward motions from a movie depicting the sagittal view of an upright human point‐light walker, walking as if on a treadmill. Inversion of the stimuli resulted in no detection of directionality. These findings suggest that biological motion displays convey information for young infants beyond that which distinguishes them from nonbiological motion; aspects of the action itself are also detected. The potential visual mechanisms underlying biological motion detection, as well as the behavioral interpretations of point‐light figures, are discussed.     

Learning to cooperate with Pavlov an adaptive strategy for the iterated Prisoner's Dilemma with noise

Conflict of interest may be modeled, heuristically, by the iterated Prisoner's Dilemma game. Although several researchers have shown that the Tit-For-Tat strategy can encourage the evolution of cooperation, this strategy can never outscore any opponent and it does poorly against its clone in a noisy environment. Here we examine the family of Pavlovian strategies which adapts its play by positive and negative conditioning, much as many animals do. Mutual cooperation will evolve in a contest with Pavlov against a wide variety of opponents and in particular against its clone. And the strategy is quite stable in a noisy environment. Although this strategy cooperates and retaliates, as does Tit-For-Tat, it is not forgiving; Pavlov will exploit altruistic strategies until he is punished by mutual defection. Moreover, Pavlovian strategies are natural models for many real life conflict-of-interest encounters as well as human and computer simulations.     

Cohesion and Enmeshment Revisited: Differentiation,Identity, and Well‐Being in Two European Cultures

We examined the nature and implications of family differentiation among adolescents facing a life transition in 2 European countries with differing family cultures. One hundred and twenty‐four Italian and 109 U.K. adolescents completed measures of family differentiation (cohesion and enmeshment), identity threat (perception of threat to the self associated with finishing school), life satisfaction, depressive symptoms, and anxiety. Confirmatory factor analyses showed that cohesion and enmeshment were distinguishable in both countries, orthogonal in the U.K. but positively correlated in Italy. Family cohesion was associated with better psychological well‐being in both countries; enmeshment was associated with poorer psychological well‐being in the U.K. but not in Italy. Structural equation models showed that effects on well‐being were fully mediated by identity threat in both cultures.
