TRADUCTION ET VALIDATION CANADIENNE-FRANÇAISE DE L'ÉCHELLE DE L'ESTIME DE SOI DE ROSENBERG*

Since the early days of psychology, the self-concept and more specifically global self-esteem has been addressed by numerous researchers in the field. Among the widely used instruments for measuring global self-esteem, Rosenberg's Self-Esteem scale (RSE) has displayed high levels of validity and reliability (Harter 1983; Wylie 1974). Through a brief (10 items) and direct approach, the RSE can be answered quickly by different age and social groups. Considering the good psychometric properties of the RSE mentioned above, and the importance of self-esteem for research in psychology, the purpose of the present four studies was to translate and validate in French the RSE Internal consistency (study 1) and confirmatory factor analyses through LISREL VI (study 2) were conducted with a French-Canadian junior college student population in order to verify the internal consistency and the unidimensional factorial structure of the scale. In addition, the construct validity (study 3) and temporal stability (study 4) of the scale were assessed. Although the present findings are preliminary in nature, they nevertheless support the reliability and validity of the Rosenberg's Self-Esteem scale in French.     

Cognitive and Behavioural Attention in Children with Low-Moderate and Heavy Doses of Prenatal Alcohol Exposure: a Systematic Review and Meta-analysis

Neuropsychology Review - Attention problems are thought to be a hallmark feature of prenatal alcohol exposure (PAE). Despite decades of research however, these findings have never been pooled to...     

Failure to construct and transfer correct representations across probability problems

Previous studies carried out on "purely random" situations (with dice or poker chips) show the difficulties encountered by people in such situations, however simple they may be. In fact, in this type of situation, prior knowledge guides spontaneous representations, and the "errors" observed could be explained by the activation of "implicit models" which form the basis of erroneous representations. 42 statistically na?ve undergraduates were given several variants of a probability problem on which errors are common. In a learning phase, subjects were given four problems involving geometric figures which were pairwise related by complementarity and equivalence relations. In a subsequent transfer phase, they were given a fifth problem involving poker chips, which was structurally isomorphic to the fourth geometric-figures problem. The findings show that people do not realize the relations between problems, and that transfer occurred only for the subset of subjects who performed correctly on the training problems of the learning phase. These results appear to have some significant implications in teaching mathematical concepts.     

Lying and executive control: an experimental investigation using ego depletion and goal neglect

This study investigated whether lying requires executive control using a reaction-time based lie test. We hypothesized that (1) goal neglect induced by a long response-stimulus interval (RSI; 5-8s) would make lying harder relative to a short RSI (.2 s) that promoted attentional focus, and (2) participants whose executive control resources were depleted by an initial executive control task would experience more difficulty to lie than control participants who performed a task that required little executive control. Across two experiments, the ego depletion manipulation did not reliably affect lying. Both experiments revealed that the cognitive cost associated with lying was larger for the long compared to the short RSI. This finding supports the idea that lying requires more executive control than truth telling. The manipulation of RSI may provide a simple, yet effective means to improve lie detection accuracy.     

L-eye to me: the combined role of Need for Cognition and facial trustworthiness in mimetic desires

Recent studies showed that stimuli are evaluated more favourably when they are perceived to capture others' attention, an effect coined "mimetic desire". The aim of the present research was to examine the combined role of Need for Cognition and target's facial trustworthiness in this effect. Participants saw movie excerpts of trustworthy and untrustworthy 3D faces (Oosterhof & Todorov, 2008) turning their attention towards one art painting and away from another art painting. Results showed that looked-at paintings were preferred to looked-away paintings when associated with a trustworthy face. However, the reversed finding was observed for paintings associated with untrustworthy faces. The latter interaction was in turn moderated by participant's Need for Cognition, with a larger reversal effect for participants scoring lower on the NFC scale. Theoretical implications of these findings are discussed.     

Representational momentum in aviation

The purpose of this study was to examine the effects of expertise on motion anticipation. We conducted 2 experiments in which novices and expert pilots viewed simulated aircraft landing scenes. The scenes were interrupted by the display of a black screen and then started again after a forward or backward shift. The participant's task was to determine whether the moving scene had been shifted forward or backward. A forward misjudgment of the final position of the moving scene was interpreted as a representational momentum (RM) effect. Experiment 1 showed that an RM effect was detected only for experts. The lack of motion anticipation on the part of novices is a surprising result for the RM literature. It could be related to scene unfamiliarity, encoding time, or shift size. Experiment 2 was run with novices only. It was aimed at testing the potential impact of 2 factors on the RM effect: scene encoding time and shift size. As a whole, the results showed that encoding time and shift size are important factors in anticipation processes in realistic dynamic situations.     

The cultural narratives of Francophone and Anglophone Quebecers: using a historical perspective to explore the relationships among collective relative deprivation, in-group entitativity, and collective esteem

Responding to calls to contextualize social psychological variables in history, the present research examines the relationship between collective relative deprivation and collective esteem using a historical perspective. We hypothesized that collective relative deprivation perceived to be experienced during an important low-point in a group's history serves to define the group's current collective identity, which is in turn associated with collective esteem. In Study 1, cultural narrative interviews were conducted with Francophone and Anglophone Quebecers in order to identify key historical chapters for these groups and to examine the extent to which historical low-points were identity-defining features of their narratives. In Study 2, using the information obtained from these narratives, collective relative deprivation was explored across group members' perceived histories and related to current in-group entitativity and collective esteem. The relationship between collective relative deprivation thought to be experienced by one's group during a historical low-point and collective esteem was positive for both Anglophone and Francophone Quebecers and was mediated by in-group entitativity. Collective relative deprivation perceived to be experienced during a historical low-point serves to define one's collective identity, which is in turn associated with greater collective esteem.     

Lower back pain in nurses working in home care: linked to work–family conflict,emotional dissonance,and appreciation?

In industrial countries home care services for elderly people living in the community are growing rapidly. Home care nursing is intensive and the nurses often suffer from musculoskeletal pain. Time pressure and job control are job-related factors linked to the risk of experiencing lower back pain (LBP) and LBP-related work impairment. This survey investigated whether work-family conflict (WFC), emotional dissonance and being appreciated at work have incremental predictive value. Responses were obtained from 125 home care nurses (63% response rate). Multiple linear regression showed that emotional dissonance and being appreciated at work predicted LBP intensity and LBP-related disability independently of time pressure and job control. WFC was not a predictor of LBP-related disability in multiple regression analyses despite a zero-order correlation with it. Redesigning the working pattern of home care nurses to reduce the emotional demands and improve appreciation of their work might reduce the incidence of LBP in this group.     

Dynamic perception in chess

The present study examines the dynamic aspects of perceptual processes in expert chess players. This topic is approached in terms of the anticipation processes carried out by experienced players during the encoding of chess positions. The aim of the first experiment, which used a short-term comparison task, was to stress the role of anticipation, which allows expert players to focus their attention on the area of the studied position where they expect the likely standard move to occur. The second experiment used a long-term recognition task. The results showed that expert players made many false recognitions on the new positions that could be expected from the positions presented in the preliminary study phase. Taken together, the results of the two experiments highlight the anticipatory component of expert perception.
