Stéréotypes de poids,jugement de valeur et de recrutabilité : les rôles modérateurs du sexe et de la personnalité

ObjectiveThe existing literature testifies to the presence of discrimination against obese people in hiring. The present study aimed to test the effects of candidates’ weight on value judgment and recruitability by taking into account their gender and personality. The study using the judges’ paradigm involved a sample of 279 recruiters. The recruiters were asked to judge eight fictitious CVs including a photo of the candidate, their education, their work experience and their answers to a personality test (proactive or reactive personality). The target job was a medical laboratory technician.ResultsAnalyses of variance revealed significant effects of applicants’ weight, and proactivity on judgements of agreeableness, effort, competence and recruitability. Indeed, obese people are discriminated against in hiring whereas proactivity would be a variable increasing the recruitability judgment. Moreover, the gender of applicants alone is no longer a variable that encourages discrimination.ConclusionThis study opens up a new field of research on proactivity as a social norm of judgement and corroborates previous studies on weight discrimination in personnel selection. The limitations of the study open up new avenues of research.     

Weight discrimination in helping behavior

IntroductionAlthough obesity stigma is pervasive, relatively little research has examined the extent to which the discrimination obese individuals experience extends to helping behavior.ObjectivesThe purpose of the current set of experiments was to determine whether strangers help heavy individuals less than non-heavy individuals, and to examine the impact that moderating cues (e.g., justifying or suppressing prejudice, Crandall & Eshleman, 2003) of weight-based discrimination and gender might have on helping behavior.Study 1The first study was an experiment conducted online through MTurk. Participants rated their willingness to support a proposed charity event and their perceptions of the event organizer, whose picture was manipulated to be heavy or non-heavy. We found evidence that people were less willing to help and held more negative perceptions of heavy (than non-heavy) individuals.Study 2The second study was a field experiment in which confederates either wearing or not wearing obesity prosthetics solicited help from others on a college campus. Relative to the non-heavy, heavy individuals again were less likely to be helped and received more impolite interpersonal treatment, as rated by observers. Additionally, women were denigrated more than men for being heavy, but cues that suppressed discrimination helped increase the amount of help received and the politeness of strangers.ConclusionThe overt and subtle discrimination overweight individuals experience extends to situations when they are asking for help, and this is especially the case for heavy women. However, displaying stereotype-inconsistent cues benefit overweight individuals by increasing the likelihood of them being helped and treated well.     

Great apes’ performance in discriminating weight and achromatic color

Much work has been done on visual discrimination in primates over the past decade. In contrast, very little is known about the relevance of non-visual information in discrimination learning. We investigated weight and achromatic color (color, henceforth) discrimination in bonobos, gorillas and orangutans, using the exchange paradigm in which subjects have to give objects to the experimenter in order to receive a reward. Unlike previous studies, subjects were not trained to lift objects because lifting the objects was an integral part of the exchange procedure. This methodology also allowed us a direct comparison between visual and weight discrimination. We presented 12 subjects (5 bonobos, 2 gorillas and 5 orangutans) with two sets of objects corresponding to two conditions. The objects in the color condition (white/black) differed only in color and those in the weight condition (light/heavy) differed only in weight. Five apes learned to discriminate weight and six to discriminate color. Subjects learned color discrimination faster than weight discrimination. Our results suggest that bonobos and orangutans are sensitive to differences in weight and able to learn discriminating objects that differ in this property.     

Casting weight goal as a function of weight status among a representative population-based sample of adolescents

This paper pursues two objectives: (1) to estimate proportions of adolescents with a weight goal that matched and mismatched weight status, and (2) to identify correlates of a mismatched weight goal. Data were from a representative population-based sample of adolescents (n = 2346, 51% female; 91.5% complete data). Results showed that 69% of adolescents had a weight goal that matched weight status whereas 31% had a weight goal that mismatched weight status. Body dissatisfaction was a significant predictor of having a mismatched weight goal for both sexes while elevated psychological distress was a predictor among girls. Being body dissatisfied mediated the association between psychological distress and having a mismatched weight goal among girls. Casting weight goal as a function of weight status may allow for a better understanding of overall weight management strategies.

Knowledge and credit

A widely accepted view in recent work in epistemology is that knowledge is a cognitive achievement that is properly creditable to those subjects who possess it. More precisely, according to the Credit View of Knowledge, if S knows that p, then S deserves credit for truly believing that p. In spite of its intuitive appeal and explanatory power, I have elsewhere argued that the Credit View is false. Various responses have been offered to my argument and I here consider each of these objections in turn. I show that none succeeds in undermining my argument and, thus, my original conclusion stands—the Credit View of Knowledge is false.

Contextual effects on number-time interaction

Time perception has long been known to be affected by numerical representations. Recent studies further demonstrate that when participants estimate the duration of Arabic numbers, number magnitude, though task-irrelevant, biases duration judgment to produce underestimation for smaller numbers and overestimation for larger numbers. Such effects were found in the present study to be significantly reduced when a weight unit gram was suffixed to the numbers rendering the mental magnitude differences between different numbers less distinctive. The effects were enhanced when a different unit kilogram was suffixed to the numbers enlarging the perceived magnitude differences between different numbers. The results indicate that effects of number magnitude on duration estimation should not be attributed to the mathematical differences between numbers but to how the numbers are perceived to differ from each other in magnitude in specific contexts when they denote concrete items. The results also provide new evidence for the theoretical proposal of a common generalized magnitude system and indicate that the system must be extended to include other action-oriented magnitudes, such as weight.     

重建世界的人文精神--牟宗三儒家式的人文主义

牟宗三对世界人文精神的重建,乃是出于他对人类精神趋下的时代悲情和他对人文主义精神的信念,顺康德的精神路向,本儒家的心性之学,绍续和改造西方近代人文主义,完成于“三统并建”的学说之中,旨在把宗教、哲学、科学和艺术统一起来,表现为“儒家式的人文主义”。它既特别重视人性、个性与人格,又强调道德主体是其根源和基础。牟要以儒家的理想和价值来安置人性、个性与人格,固然是要使个人免于泛滥为自然主义、浪漫主义与工具主义的牺牲品,然而其更深层的基本的关怀和用心,乃在于从他所主张的“道德的形上学”的高度为人提供一个安身立命之本．使人成为一个具体的全面的发展的人。     

The Effects of Weight Loss Attempts, Exercise Initiation, and Dietary Practices on Health Related Quality of Life

This study (N = 98) randomly placed participants in either a higher protein or American Heart Association diet group with each group initiating an aerobic exercise program. Body composition (BC) was measured using four different methodologies (DEXA, BIA, skinfold, BMI) along with height and weight, while Health-Related Quality of Life (HRQOL) changes were measured using the Medical Outcomes Short Form 36 (SF-36). There were no significant time/diet interactions in HRQOL scores, body fat measures, and weight with the exception of Role-Physical scores (p = .006) with posttest scores higher in participants in Diet 1. Role-Physical scores changed significantly in participants in Diet 1 (p = .0001) and Diet 2 (p = .026) with higher posttest scores in each group. Social functioning had a significant main effect for time in both groups with pretest scores in both diet groups lower than their respective posttest scores (p = .015). HRQOL pretest scores were not significantly different between groups at baseline (p = .56). ANOVA revealed no significant differences in average calories between groups (p = .88). Analysis revealed no differences in exercise in minutes (p = .66) nor statistically significant changes in BC or weight (p = .65). Conclusions: Improvements in HRQOL were demonstrated in two subscales related to physiological and psychological functioning. These novel findings add to literature suggesting that HRQOL, at least concerning social functioning, work and other daily activities (Role-Physical) may improve by initiating an exercise and dietary program even when weight loss or BC improvements have been unsuccessful.     

Investigation of ethnic differences in body image between Hispanic/biethnic-Hispanic and non-Hispanic White preadolescent girls

The extent to which the construct of body image is measurement invariant across ethnic groups is an important consideration for studies examining ethnic differences and characteristics that influence body image disturbances. However, the literature examining the body image construct as a function of ethnic group membership is limited. The primary aim of this study was to investigate whether Hispanic/biethnic-Hispanic and non-Hispanic White preadolescent girls (aged 8 through 12 years old; N = 141) had fundamentally different conceptualizations of body image in a low to low/middle socioeconomic status school-based sample. Our findings suggest that the measurement construct of body image was similar and relatively stable for Hispanic/biethnic-Hispanic and non-Hispanic White preadolescent girls. In addition, the body image construct was predictably related to disordered eating symptoms in both groups, with different dimensions of body image differentially predictive by ethnic group. Overall, body image appears to be a meaningful construct with similar measurement meanings across Hispanic/biethnic-Hispanic and non-Hispanic White ethnic groups.
