Distance de pouvoir et auto-évaluation de l’efficacité d’une équipe de travail

We introduce a study concerning relation between power and the evaluation of the effectiveness of working teams (Savoie & Brunet, 2000). The power model of Mulder lead to postulate a relation between power distance in the team and the evaluation of the effectiveness. We collected a series of measurements in working teams composed of students engineers. Results allow proving such relation.     

Self-Regulation Failure Reduces the Effect Alcohol Portrayals in Movies on Indirect Attitudes toward Alcohol

Abstract

We investigated the cognitive mechanisms underlying change in implicit cognitions following exposure to alcohol portrayals. More precisely, we tested in an experimental study whether this change depends on controlled or automatic processes by putting participants in a state of self-regulatory fatigue prior to being exposed to alcohol portrayals. Ninety participants were randomly assigned to a 2 (attitude measure: before vs after) × 2 (alcohol portrayal: yes vs no) × 2 (ego depletion: yes vs no) mixed design to assess whether the effects of alcohol portrayals affected cognitive resources. It was hypothesized that alcohol portrayals would have more of an impact on participants submitted to an ego-depletion task. We found a change in attitudes toward alcohol only for participants that had been exposed to alcohol portrayals, and who had not been cognitively depleted. These results suggest that these changes rely on controlled, resource-dependent processes rather than on purely associative and automatic processes. Implications regarding alcohol advertising effects on public health are discussed.     

Effect of marital satisfaction on self-regulation efforts in couples: Value of heart rate variability measurements

This study explored self-regulatory efforts during the viewing of couple interactions and their association with relationship satisfaction. High-frequency heart rate variability (HF-HRV) was measured for each participant during a video recall of a recent couple interaction to quantify the self-regulatory processes governed by parasympathetic activity. Among 30 couples, HF-HRV was measured continuously during three specific periods to explore its change over time using a video-recall procedure: (1) resting state; (2) viewing of couple interactions (expressing daily life situations and conflictual interactions); and (3) recovery. Results of multilevel models revealed a u-shaped pattern of HF-HRV responses for men and women across the three periods with a nadir at the midway through the process. This pattern of physiological change (vagal suppression) reflects a flexible response to a stressful situation. Nevertheless, the pattern of physiological responses varied according to the level of relationship satisfaction. Men who were more satisfied in their couple relationship presented greater vagal suppression than dissatisfied men. In contrast, no significant HF-HRV changes were found in women over the different periods of the video-recall procedure and no moderating effect of relationship satisfaction. We discuss the different patterns of physiological responses observed both for men and women in terms of interindividual variability according to the level of their relationship satisfaction. The present study highlights the important role of relationship satisfaction in regulatory processes.     

Proper methodologies for psychological and sociological studies conducted via the Internet

This paper outlines specific methodologies for conducting research via computer networks. We discuss advantages of Internet experimentation over previous modes of telecommunication-facilitated research and characterize features of studies that can benefit from Internet access and those which are unlikely to. We point out pitfalls and suggest a range of potential solutions in terms of specific practical techniques for managing the design, dissemination, and collection of Internet materials. We also discuss techniques for minimizing attrition and for adapting to recalcitrance presented by “hacker” vandalism.
