Target Characteristics

Past social projection research has mainly focused on target characteristics as a moderator of projective effects. The current research considers the power of the perceiver and how it affects projection of competence and warmth. In three studies, participants first rated themselves on a list of traits/preferences, then performed a power manipulation task, and, finally, rated a target person on the same list. Studies 1 and 2 reveal that the effect of power on social projection is moderated by dimension of judgment: high-power/low-power participants project more on competence/warmth than low-power/high-power participants. A meta-analysis conducted on Studies 1, 2, 3, and two additional studies confirmed those results. Study 3 additionally shows that high power increases the salience of competence, whereas low power increases the salience of warmth. Implications for both the power and the social perception literatures are discussed.

Background: Although high power, shorter duration (HPSD) ablation and low power, longer duration (LPLD) ablation strategies for atrial fibrillation (AF) are frequently advocated to enhance safety and efficacy, there exists a need for comparative data from large populations. We performed a meta-analysis to compare arrhythmia-free survival, procedure time and complications rates between the two strategies. Methods: We searched the databases of MEDLINE and EMBASE from inception to April 2020. Included studies were case-control studies, cohort studies, or randomized controlled trials that compared patients undergoing HPSD and LPLD strategies for AF ablation and reported either of the following outcomes: freedom from atrial tachyarrhythmia (AT) including AF and atrial flutter, procedure time, or periprocedural complications. Data from each study were combined using the random-effects model to calculate odds ratio (OR) and weighted mean difference (WMD) with 95% confidence interval (CI). Results: Ten studies from 2006 to 2020 involving 2,189 patients were included (1,350 patients underwent HPSD strategy and 839 patients underwent LPLD strategy). Both HPSD and LPLD strategies resulted in a similar freedom from AT at 12-month follow-up (OR=1.36, 95% CI:0.91-2.04, p=0.13, Figure 1A). HPSD strategy did result in a significant reduction in total procedure time (WMD=47.34, 95% CI:29.47-65.21, p<0.001, Figure 1B) compared to LPSD. HPSD wasn’t associated with reduction in esophageal ulcer/arterioesophageal fistula (OR=0.35, 95%CI=0.12-1.06, p=0.06) or pericardial effusion/cardiac tamponade (OR=0.96, 95%CI: 0.24-3.79, p=0.95) Conclusions: In this large meta-analysis both LPLD and HPSD are equally effective and safe. Although HPSD is often advocated to reduce esophageal injury, risk was similar between approaches. However, HPSD strategy significantly lowers procedure times.

Power Perception

Very early on, children understand the hierarchical dimension of the social environment and use a variety of cues to guess who has more power in an interaction. A crucial aspect of power perception lies in the evaluation of high-power and low-power individuals. The current study examined the evaluation of power by preschoolers through social influence. Past research has shown that preschoolers take social category information into account when expressing their preferences. In particular, they tend align their preferences with those of same-gender and same-age individuals. In the current study, 4- and 5-year-old children were presented with a power interaction between two children through body postures and were asked whether they would prefer the same items as those preferred by the high-power child or those preferred by the low-power child. Overall, the participants did not choose the items preferred by the high-power child significantly more often than those preferred by the low-power child. However, unexpected gender effects were found and indicated that the power asymmetry influenced more male than female participants. Indeed, when they saw a power interaction between two boys (Experiments 1 and 2), male participants aligned their choices with those of the high-power boy more than with those of the low-power boy. However, when male participants saw an interaction between two girls (Experiment 3), an opposite pattern was observed: they aligned their choices with those of the low-power girl more than with those of the high-power girl. In contrast, in the three experiments, there were approximately as many girls who aligned their preferences with those of the high-power child as there were girls who aligned their preferences with those of the low-power child. The current study reveals the importance of taking gender into account, both at the level of participants and stimuli, in the evaluation of power by preschoolers.

Abstract. Power facilitates goal pursuit, but how does power affect the way people respond to conflict between their multiple goals? Our results showed that higher trait power was associated with reduced experience of conflict in scenarios describing multiple goals (Study 1) and between personal goals (Study 2). Moreover, manipulated low power increased individuals’ experience of goal conflict relative to high power and a control condition (Studies 3 and 4), with the consequence that they planned to invest less into the pursuit of their goals in the future. With its focus on multiple goals and individuals’ experiences during goal pursuit rather than objective performance, the present research uses new angles to examine power effects on goal pursuit.
