Media representations of environmental issues: From scientific to political discourse

IntroductionThe media is considered to be a social agent that intervenes in the elaboration of social representations of environmental issues.ObjectiveThis research analyses media representations of environmental issues and how they have been constructed and transformed from the Rio Summit in 1992 to 2006. The authors adopted a constructionist approach based on the theory of social representations (Moscovici, 1961/1976) to describe the generation of information by the mass media.MethodA sample of 1039 news articles from two Spanish newspapers (La Vanguardia and El País) was analysed. The period of study ranged from the Rio Earth Summit to several years after the Johannesburg Summit (1992–2006), and the study analyses both the content and form of the environmental news.ResultsThis longitudinal study shows not only an increase in environmental news during the period of analysis but also an increased variety of themes addressed and represented. The results evidence significant urban problems in recent years. The environment has shifted from being associated with nature to being predominately associated with the urban environment.ConclusionThe results suggest that there has been a movement from scientific to political discourse and a change towards greater reflection and social recognition of the relevance of environmental issues.     

Les effets des demandes au travail et de la justice organisationnelle sur l’épuisement professionnel : quels effets médiateurs du soutien social et de l’estime de soi ?

This study focuses on the burnout framework and aims at examining the links between, on the one hand, the psychological burden, decision latitude, organizational justice and self-esteem and, on the other hand, the burnout. We measure the mediator effect of the social support. The data derived from a questionnaire submitted to 122 managers allowed us to establish a correlation matrix, linear regressions on the burnout and mediation analyzes. The results indicate that the predominant variables would be the organizational justice, support from colleagues, self-esteem and affects. The mediator effect of the social support between the different types of justice and the burnout was partially validated.     

How school-based dancing classes change affective and collaborative networks of adolescents

ObjectiveThe present research investigated the effects of adolescents' co-participation in a federally funded dance intervention project on students' affective and collaborative networks. In the intervention, students instructed by professional dancers collaboratively developed a dance-choreography during regular class hours in student groups. We expected that the number of reciprocated affective and collaborative ties should increase in classrooms participating in the intervention, but that boys should particularly benefit from the intervention.DesignWe used a quasi-experimental untreated control group design with dependent pretest and posttest samples. Participants were 421 youths (48% boys) in 23 classrooms of primary and secondary schools in Berlin, Germany. Of these, 226 (54%) participated in the intervention. Classrooms from the same grade and school were recruited as comparison groups. We assessed both networks using sociometric questionnaires.Method/ResultsWe found a significant Treatment × Gender interaction showing that reciprocated collaborative relations increased only for boys in the intervention group. Analyses probing potential mechanisms showed this was due to their choosing more collaboration partners, in particular more girls.ConclusionFindings suggest that school-based dancing programs encouraging coordinated physical activity in student groups may be particularly beneficial for boys, encouraging them to consider girls as academic cooperation partners and to proactively develop their collaborative networks.     

Decision Difficulty in the Age of Consumer Empowerment

In this review, we examine the impact of two key factors of consumer empowerment–choice freedom and expansion of information--on the choice difficulty consumers experience in today’s decision environment. We posit that though these two consumer empowerment factors offer numerous potential benefits, they also can magnify such sources of decision difficulty as task complexity, tradeoff difficulty, and preference uncertainty. Next we review several key moderators, including consumer knowledge, mental representation, and maximization tendencies as well as information type and organization, that can exacerbate or mitigate the effect of these consumer empowerment factors on decision difficultly outcomes. Lastly, we examine the effectiveness of decision aids in assisting consumers navigate the complexity of today’s decision environment, and we identify areas for future investigation.     

领导力的社会认同理论：主要内容及研究进展

作为“以下属为中心”的领导力理论,领导力的社会认同理论是社会心理学与领导力研究结合的代表.该理论采用社会认同解释领导力产生和发挥作用的过程,主要命题为：（1）群体成员通过社会认同选择有效的领导,具有高群体原型代表性的领导者最具有效性;（2）领导者可以通过塑造下属成员的社会认同来实施领导.除了以上内容外,还对该理论的实验证据及优缺点也进行了系统阐述,同时与其它领导力理论进行了整合,最后提出了未来研究的方向.     

Unconscious cues bias first saccades in a free-saccade task

Visual–spatial attention can be biased towards salient visual information without visual awareness. It is unclear, however, whether such bias can further influence free-choices such as saccades in a free viewing task. In our experiment, we presented visual cues below awareness threshold immediately before people made free saccades. Our results showed that masked cues could influence the direction and latency of the first free saccade, suggesting that salient visual information can unconsciously influence free actions.     

Good intentions gone awry? Effects of weight-related social control on health and well-being

A negative body image has been associated with a variety of negative health and well-being outcomes. Social pressures from others, in the form of weight-related social control, may serve to exacerbate this effect, especially for college-aged women. Undergraduate students (N = 399) completed a variety of questionnaires assessing weight-related social control, well-being, and diet and exercise behaviors. The results suggest that weight is associated with a variety of negative health and well-being outcomes and particularly for women, weight-related social control is also associated with these negative effects. In addition, men of higher body mass indexes (BMIs) or higher self-perceived weight did not experience negative health and well-being outcomes to the same degree that overweight women did. Parents in particular seem to instigate weight-related social control to change students’ diet and exercise behaviors. These results help clarify the effects of weight-related social control in a college population, where weight may be especially important.     

Collaboration inflation: Egocentric source monitoring errors following collaborative remembering

Following collaborative remembering, people may adopt their partner's contributions as their own memory. In two studies, we asked people to study partially overlapping lists of words. During collaborative remembering, dyads either worked to include all words no matter who studied them or limited recall to only words studied by both dyad members. This differential focus on source information during collaborative recall impacted performance on a later source memory test. Nonetheless we found frequent source monitoring errors that displayed an egocentric bias. People were more likely to claim their partner's contributions as their own memories than attribute their memories to their partners. In collaborative remembering, people work to construct an agreed upon version of the past that quickly becomes each individual's memory.     

Improved classification of mammograms following idealized training

People often make decisions by stochastically retrieving a small set of relevant memories. This limited retrieval implies that human performance can be improved by training on idealized category distributions (Giguère & Love, 2013). Here, we evaluate whether the benefits of idealized training extend to categorization of real-world stimuli, namely classifying mammograms as normal or tumorous. Participants in the idealized condition were trained exclusively on items that, according to a norming study, were relatively unambiguous. Participants in the actual condition were trained on a representative range of items. Despite being exclusively trained on easy items, idealized-condition participants were more accurate than those in the actual condition when tested on a range of item types. However, idealized participants experienced difficulties when test items were very dissimilar from training cases. The benefits of idealization, attributable to reducing noise arising from cognitive limitations in memory retrieval, suggest ways to improve real-world decision making.     

Remembering stories together: Social contagion and the moderating influence of disagreements in conversations

Although remembering often occurs with conversations, the effects of its pragmatics on memory are rarely examined. We studied the effect of two pragmatic factors: (1) the presence of disagreeing and (2) the level of participation in the disagreement. In the present study, each participant read a slightly different version of four stories, thereby allowing for the possibility of social contagion through the conversation. They then jointly recounted the stories. We coded for the presence or absence of disagreements, and whether a participant contributed to the disagreement. Three factors mediated social contagion: (a) the presence or absence of an overt disagreement; (b) whether or not a member of a conversational remembering participated actively in a disagreement; and (c) how well participants remembered the original material. Both the pragmatics of conversations and quality of memory are important factors moderating social contagion.
