Is It Me or Her? How Gender Composition Evokes Interpersonally Sensitive Behavior on Collaborative Cross-Boundary Projects

This paper investigates how professional workers’ willingness to act with interpersonal sensitivity is influenced by the gender and power of their interaction partners. We call into question the idea that mixed-gender interactions involve more interpersonal sensitivity than all-male interactions primarily because women demonstrate more interpersonal sensitivity than do men. Rather, we argue that the social category “women” can evoke more sensitive behavior from others such that men as well as women contribute to an increase in sensitivity in mixed-gender interactions. We further argue that the presence of women may trigger increased sensitivity such that men can also be the recipients of more sensitivity when one or more women are present on a team. In a study of 202 management consultants, we found that the willingness to act with interpersonal sensitivity increased in interactions with women. Moreover, this effect was greater in interactions with women who had low reward power—i.e., females who better fit the expectations associated with the social category “women.” We also found team-level effects. Professionals working with mixed-gender versus all-male client teams reported a greater willingness to act with interpersonally sensitive behavior toward male client team members. Our findings show that the willingness to act with interpersonal sensitivity is context dependent and shed light on the importance of studying interaction partner-level and team-level effects on willingness to act with interpersonal sensitivity

Can Confidence Come Too Soon? Collective Efficacy, Conflict and Group Performance over Time

Groups with a strong sense of collective efficacy set more challenging goals, persist in the face of difficulty, and are ultimately more likely to succeed than groups who do not share this belief. Given the many advantages that may accrue to groups who are confident, it would be logical to advise groups to build a high level of collective efficacy as early as possible. However, we draw on Whyte’s (1998) theory of collective efficacy and groupthink, to predict that when confidence emerges at a high level toward the beginning of a group’s existence, group members may be less likely to engage in process conflict; a form of conflict that may be beneficial in the early phase of a group project. We found support for this prediction in two longitudinal studies of classroom project teams

Embodied Metaphors and Creative “Acts”

Creativity is a highly sought after skill. To inspire people’s creativity, prescriptive advice in the form of metaphors abound: We are encouraged to think outside the box, to consider the problem on one hand, then on the other hand, and to put two and two together to achieve creative breakthroughs. These metaphors suggest a connection between concrete bodily experiences and creative cognition. Inspired by recent advances on body-mind linkages under the emerging vernacular of embodied cognition, we explored for the first time whether enacting metaphors for creativity enhances creative problem-solving. In five studies, findings revealed that both physically and psychologically embodying creative metaphors promote fluency, flexibility, and/or originality in problem-solving. Going beyond prior research that focused primarily on the kind of embodiment that primes preexisting knowledge, we provide the first evidence that embodiment can also activate cognitive processes conducive for generating previously unknown ideas and connections

Evaluation of Urine CCA Assays for Detection of Schistosoma mansoni Infection in Western Kenya

Although accurate assessment of the prevalence of Schistosoma mansoni is important for the design and evaluation of control programs, the most widely used tools for diagnosis are limited by suboptimal sensitivity, slow turn-around-time, or inability to distinguish current from former infections. Recently, two tests that detect circulating cathodic antigen (CCA) in urine of patients with schistosomiasis became commercially available. As part of a larger study on schistosomiasis prevalence in young children, we evaluated the performance and diagnostic accuracy of these tests—the carbon test strip designed for use in the laboratory and the cassette format test intended for field use. In comparison to 6 Kato-Katz exams, the carbon and cassette CCA tests had sensitivities of 88.4% and 94.2% and specificities of 70.9% and 59.4%, respectively. However, because of the known limitations of the Kato-Katz assay, we also utilized latent class analysis (LCA) incorporating the CCA, Kato-Katz, and schistosome-specific antibody results to determine their sensitivities and specificities. The laboratory-based CCA test had a sensitivity of 91.7% and a specificity of 89.4% by LCA while the cassette test had a sensitivity of 96.3% and a specificity of 74.7%. The intensity of the reaction in both urine CCA tests reflected stool egg burden and their performance was not affected by the presence of soil transmitted helminth infections. Our results suggest that urine-based assays for CCA may be valuable in screening for S. mansoni infections

Circulating CD14brightCD16+ 'intermediate' monocytes exhibit enhanced parasite pattern recognition in human helminth infection.

Circulating monocyte sub-sets have recently emerged as mediators of divergent immune functions during infectious disease but their role in helminth infection has not been investigated. In this study we evaluated whether 'classical' (CD14brightCD16-), 'intermediate' (CD14brightCD16+), and 'non-classical' (CD14dimCD16+) monocyte sub-sets from peripheral blood mononuclear cells varied in both abundance and ability to bind antigenic material amongst individuals living in a region of Northern Senegal which is co-endemic for Schistosoma mansoni and S. haematobium. Monocyte recognition of excretory/secretory (E/S) products released by skin-invasive cercariae, or eggs, of S. mansoni was assessed by flow cytometry and compared between S. mansoni mono-infected, S. mansoni and S. haematobium co-infected, and uninfected participants. Each of the three monocyte sub-sets in the different infection groups bound schistosome E/S material. However, 'intermediate' CD14brightCD16+ monocytes had a significantly enhanced ability to bind cercarial and egg E/S. Moreover, this elevation of ligand binding was particularly evident in co-infected participants. This is the first demonstration of modulated parasite pattern recognition in CD14brightCD16+ intermediate monocytes during helminth infection, which may have functional consequences for the ability of infected individuals to respond immunologically to infection

Consumers believe that products work better for others

Consumers tend to see themselves in a positive light, yet we present evidence that they are pessimistic about whether they will receive a product’s benefits. In 15 studies (N¼6,547; including nine preregistered), we found that consumers believe that product efficacy is higher for others than it is for themselves. For example, consumers believe that consuming a sports drink (to satisfy thirst), medicine (to relieve pain), an online class (to learn something new), or an adult coloring book (to inspire creativity) will have a greater effect on others than on themselves. We show that this bias holds across many kinds of products and judgmenttargets, and inversely correlates with factors such as product familiarity, product usefulness, and relationship closeness with judgment-targets. Moreover, we find this bias stems from consumers’ beliefs they are more unique and less malleable than others, and that it alters the choices people make for others. We conclude by discussing implications for research on gift-giving, advice-giving, usership, and interpersonal social, health, and financial choices

The name-letter-effect in groups: sharing initials with group members increases the quality of group work.

Although the name-letter-effect has been demonstrated reliably in choice contexts, recent research has called into question the existence of the name-letter-effect-the tendency among people to make choices that bear remarkable similarity with the letters in their own name. In this paper, we propose a connection between the name-letter-effect and interpersonal, group-level behavior that has not been previously captured in the literature. Specifically, we suggest that sharing initials with other group members promotes positive feelings toward those group members that in turn affect group outcomes. Using both field and laboratory studies, we found that sharing initials with group members cause groups to perform better by demonstrating greater performance, collective efficacy, adaptive conflict, and accuracy (on a hidden-profile task). Although many studies have investigated the effects of member similarity on various outcomes, our research demonstrates how minimal a degree of similarity among members is sufficient to influence quality of group outcomes
