When the going gets tough, the tough get going: Social identification and individual effort in intergroup competition.

Based on social identity theory, the authors predicted that in ongoing intergroup competition, people’s strength of social identification will have a positive impact on their behavioral efforts on behalf of an ingroup when its current status is low, whereas this will not be the case when its current status is high. In a first experiment, male participants showed the expected pattern of behavior. Female participants, however, tended to display opposite reactions. As a possible explanation, it was argued that the experimental procedure may have inadvertently evoked a gender-based stereotype threat for female participants. In an attempt to obtain more consistent support for their hypothesis, the authors therefore replicated the experiment with modifications to avoid such a threat. These changes proved to be effective in the sense that this time the predicted interaction effect between ingroup identification and current group status was obtained for both male and female participants

Showing engagement or not:The influence of social identification and group deadlines on individual control strategies

People often work together in groups that have to reach goals in a given time frame. Nonetheless, the impact of deadlines on group members’ self-control has not been studied so far. Here this topic is addressed by integrating the action-phase model (Heckhausen, 1999), which postulates the use of different self-control strategies during individual-level goal pursuit, with the social identity approach. It was predicted and found in two studies that highly identified group members, in contrast to those who were only weakly identified, responded to a group’s deadline phase (pre vs. post) by showing phase-appropriate patterns of engagement and disengagement. Study 1 measured identification and assessed intentions and behavioral indicators of self-control. Study 2 manipulated identification and assessed self-reports of intended self-control strategies. Overall, the findings corroborate the notion that the social self can serve as a basis for self-regulation

How to overcome the detrimental effects of noise in social interaction: the benefits of generosity

Interpersonal misunderstanding is often rooted in noise, or discrepancies between intended and actual outcomes for an interaction partner due to unintended errors (e.g., not being able to respond to an E-mail because of a local network breakdown). How can one effectively cope with noise in social dilemmas, situations in which self-interest and collective interests are conflicting? Consistent with hypotheses, the present research revealed that incidents of noise exert a detrimental effect on level of cooperation when a partner follows strict reciprocity (i.e., tit for tat) but that this effect can be overcome if a partner behaves somewhat more cooperatively than the actor did in the previous interaction (i.e., tit for tat plus 1). Also, when noise was present, tit for tat plus 1 elicited greater levels of cooperation than did tit for tat, thereby underscoring the benefits of adding generosity to reciprocity in coping with noise in social dilemmas. The Discussion outlines implications of the present work for theories focusing on self-presentation and attribution, communication, and trust and prorelationship behavior

Determinants and clinical outcome of uptitration of ACE-inhibitor and beta-blocker in patients with heart failure:a prospective European study

Introduction: Despite clear guidelines recommendations, most patients with heart failure and reduced ejection–fraction (HFrEF) do not attain guideline-recommended target doses. We aimed to investigate characteristics and for treatment-indication-bias corrected clinical outcome of patients with HFrEF that did not reach recommended treatment doses of ACE-inhibitors/Angiotensin receptor blockers (ARBs) and/or beta-blockers. Methods and results: BIOSTAT-CHF was specifically designed to study uptitration of ACE-inhibitors/ARBs and/or beta-blockers in 2516 heart failure patients from 69 centres in 11 European countries who were selected if they were suboptimally treated while initiation or uptitration was anticipated and encouraged. Patients who died during the uptitration period (n = 151) and patients with a LVEF > 40% (n = 242) were excluded. Median follow up was 21 months. We studied 2100 HFrEF patients (76% male; mean age 68 ±12), of which 22% achieved the recommended treatment dose for ACE-inhibitor/ARB and 12% of beta-blocker. There were marked differences between European countries. Reaching <50% of the recommended ACE-inhibitor/ARB and beta-blocker dose was associated with an increased risk of death and/or heart failure hospitalization. Patients reaching 50–99% of the recommended ACE-inhibitor/ARB and/or beta-blocker dose had comparable risk of death and/or heart failure hospitalization to those reaching ≥100%. Patients not reaching recommended dose because of symptoms, side effects and non-cardiac organ dysfunction had the highest mortality rate (for ACE-inhibitor/ARB: HR 1.72; 95% CI 1.43–2.01; for beta-blocker: HR 1.70; 95% CI 1.36–2.05). Conclusion: Patients with HFrEF who were treated with less than 50% of recommended dose of ACE-inhibitors/ARBs and beta-blockers seemed to have a greater risk of death and/or heart failure hospitalization compared with patients reaching ≥100%

How to cope with "noise" social dilemmas: The benefits of communication

Interactions in social life may be seriously affected by negative noise, whereby actual or perceived behavior is less cooperative than was intended (e.g., arriving late due to an unforeseen traffic jam). The present research examines whether negative noise exerts detrimental effects on impressions and cooperation and whether such effects could be reduced by communication. Consistent with hypotheses, Study 1 revealed that negative noise exerts detrimental effects on both impressions of partners' benign intent and cooperation and that these detrimental effects could be effectively reduced by communication about noise. Study 2 replicated both findings but only for individuals with low trust. Mediation analysis revealed that impressions of benign intent and prosocial interaction goals underlie the positive effects of communication on cooperation
