Team tenure and team performance: A meta-analysis and process model

Team tenure is a key component of models of team effectiveness. However, the nature of the relationship between team tenure and team performance is unclear due to underdeveloped theory on the nature of team tenure, various unintegrated theoretical conceptualizations of team tenure, and mixed empirical findings. Further, there is a lack of theory as to the intervening team processes and emergent states that account for the “black box” of the team tenure–team performance relationship. Accordingly, we conducted meta-analyses of the relationships of team tenure with team processes and performance. Our results, based on 622 effect sizes reported in 169 studies, show that team tenure, conceptualized as additive team tenure, collective team tenure, and team tenure dispersion, is positively related to team performance. Relative weights analysis found additive team tenure to be a relatively more important predictor of team performance than collective team tenure or team tenure dispersion. We found that team cognition, motivational-affective states, and behavioral processes mediate the relationships of additive team tenure, collective team tenure, and team tenure dispersion with team performance, respectively. We discuss the implications of these findings for research and practice.     

Anxiety-linked expectancy bias across the adult lifespan

Anxiety is characterised by a negative expectancy bias, such that anxious individuals report negatively distorted expectations about the future. Contrary to anxiety, ageing is characterised by a positivity effect, such that ageing is associated with a tendency to attend to and remember positive information, relative to negative information. The current study integrates these literatures to examine anxiety- and age-linked biases when thinking about the future. Participants (N=1,109) completed a procedure that involved reading valenced scenarios (positive, negative, or ambiguous) and then rating the likelihood of future valenced events occurring. Results suggest that ageing and anxiety have independent and opposing effects. Heightened anxiety was associated with a reduced expectancy for positive events, regardless of the scenarios’ current emotional valence, whereas increased age was associated with an inflated expectancy for positive events, which was strongest when individuals were processing socially relevant or negative scenarios.     

Why is the sunny side always up? Explaining the spatial mapping of concepts by language use

Humans appear to rely on spatial mappings to represent and describe concepts. The conceptual cuing effect describes the tendency for participants to orient attention to a spatial location following the presentation of an unrelated cue word (e.g., orienting attention upward after reading the word sky). To date, such effects have predominately been explained within the embodied cognition framework, according to which people’s attention is oriented on the basis of prior experience (e.g., sky → up via perceptual simulation). However, this does not provide a compelling explanation for how abstract words have the same ability to orient attention. Why, for example, does dream also orient attention upward? We report on an experiment that investigated the role of language use (specifically, collocation between concept words and spatial words for up and down dimensions) and found that it predicted the cuing effect. The results suggest that language usage patterns may be instrumental in explaining conceptual cuing.     

Disentangling the Effects of Self Leader Perceptions and Ideal Leader Prototypes on Leader Judgments Using Loglinear Modeling With Latent Variables

This study clarifies the relationships among self leader perceptions, ideal leader prototypes, and leader judgments among college students using latent profile analysis (LPA) and log-linear modeling. LPA was used to identify subgroups of individuals with unique patterns of attributes for self and ideal leaders, providing a holistic view of leadership and how multiple attributes work together within individuals. LPA was also used to identify subgroups of individuals with unique patterns of judgments of leader effectiveness. After identification of subgroups (i.e., profiles), log-linear modeling was used to test 1 baseline model and 5 sets of hypothesized associations among self leader profiles, ideal leader profiles, and leader judgment profiles. Results suggest that self leader profiles are related to ideal leader profiles, which in turn are related to leader judgment profiles, but that there is no direct relation between self leader profiles and leader judgment profiles.

Pediatric Sub-specialist Controversies in the Treatment of Congenital Heart Disease in Trisomy 13 or 18

Trisomy 13 and 18 are associated with congenital heart disease. Cardiac palliation has been reported in the literature, but is not usually done in this population. Thus, a multi-disciplinary team may experience controversy in formulating a care plan that includes cardiac intervention. Our objective was to determine differences in recommendations for cardiac intervention in this population between physicians specializing in pediatric cardiac critical care, neonatology, and genetics. A web-based survey was performed between April 2007 and August 2008. This survey evaluated surgical and transcatheter cardiac palliations that had been performed for individuals with trisomy 13 or 18 at the respondent’s institution, the respondent’s recommendations for cardiac intervention in hypothetical symptomatic patients with trisomy 13 or trisomy 18 and the influence of parental preference on these recommendations. Eight hundred fifty-nine responses were obtained from a primarily academic practice setting (59%). Cardiologists were most likely to recommend intervention; low risk interventions were recommended by 32% of cardiologists, 7% of neonatologists and 20% of geneticists. Parental request to intervene resulted in a 3 fold increased in the likelihood of all specialist recommending intervention. Counseling of families frequently occurred by multiple sub specialists (50%) and there was frequently (71%) a difference in opinion. Individuals with trisomy 13 or 18 are receiving cardiac intervention at many institutions. Cardiologists were more likely than geneticists or neonatologists to recommend intervention on all heart lesions other than single ventricle palliation which no specialists recommended. Parental wishes that “everything be done” significantly influenced all specialists’ recommendations.     

It is irrelevant,but it matters: Using confluence theory to predict the influence of beliefs on evaluations,attitudes, and intentions

The present research is based on the notion of confluence—that associated mental elements have a tendency to become more consistent with each other over time, even if some of them are logically irrelevant to the issue at hand. This idea was applied to a voting paradigm where participants were exposed to varying numbers of valenced beliefs about a candidate. Two experiments tested the idea that although valenced beliefs influence attributions and voting intentions, there is an additional process whereby evaluations of irrelevant beliefs also are influenced. Not surprisingly, as more positive or negative beliefs were presented, voting intentions became more positive or more negative, respectively. More dramatically, however, positive or negative evaluations of irrelevant beliefs became more extreme in the direction of the presented items as more of them were presented. An additional experiment tested alternative mechanisms. Copyright © 2012 John Wiley & Sons, Ltd.     

Scared stiff: The influence of anxiety on the perception of action capabilities

Influences on the perception of affordances (i.e., opportunities for actions) have been primarily studied by manipulating the functional morphology of the body. However, affordances are not just determined by the functional morphology of the perceiver, but also by the physiological state of the perceiver. States of anxiety have been shown to lead to marked changes in individuals' physiological state and their behaviour. To assess the influence of emotional state on affordance perception, the perception of action capabilities in near space was examined after participants completed an anxiety-provoking task. Anxiety was induced immediately prior to tasks that assessed participants' perceived reaching ability in Experiment 1, grasping ability in Experiment 2, and the ability to pass their hands through apertures in Experiment 3. Results indicated that those participants who experienced changes in anxiety underestimated their reaching, grasping, and passing ability compared to non-anxious participants. In other words, anxious participants were more conservative in their estimations of their action capabilities. These results suggest that anxiety influences the perception for affordances in near space and are consistent with the notion that anxiety induces withdrawal behaviours.
