Teams that have positive beliefs about their capability tend to perform more effectively. However, relatively little is known about the nature and change of different types of team capability beliefs. Team potency and team efficacy are two approaches to understanding team capability beliefs, but few studies have considered these beliefs simultaneously. We investigate their distinctiveness and relative predictive power. Additionally, we propose two types of team efficacy: team outcome efficacy and team process efficacy. In two longitudinal samples of executive MBA study teams (sample 1, N=213 individuals in 41 teams; sample 2, N=360 individuals in 89 teams), we showed that team potency, team outcome efficacy, and team process efficacy are factorially distinct and measure invariant at four time points over 7 months (except for high levels of team outcome efficacy for which factorial invariance emerged). We also show differential predictive validity. Team outcome efficacy was the strongest predictor of objective team performance, whereas team process efficacy was the best predictor of citizenship behaviours. Team potency predicted both outcomes, albeit more weakly. Collectively, the findings show the value of a more fine‐grained approach to teams' capability beliefs, including a new validated measure of team process efficacy. 相似文献

The history of scholarship on negation tracks and illuminates the major developments in the history of metaphysics, philosophy of language, and philosophy of mind, from Parmenides, Plato and Aristotle through Frege, Russell, and Wittgenstein to contemporary formal theorists. Our perspective focuses on the catalytic role played by the 20th century philosopher of language Paul Grice, whose views on negation serve as a fulcrum for his attempt to bridge the (neo-)Traditionalist and Formalist traditions in logical thought. Grice's remarks on negation and speaker meaning and the elaboration of his ideas by subsequent neo-Griceans are summarized and situated within a broader picture of the role of contradictory and contrary negation in the frameworks of Aristotelians, Medievals, early modern schoolmaster-logicians, 19th and early 20th century neo-Idealists and Formalists, Oxford ordinary-language analytics, practitioners of classical and non-classical logics, and a range of other philosophers and linguists. Particular attention is paid to the relations between negation and the other operators of propositional and predicate calculus. Implications for accounts of the semantics and pragmatics of natural language are also pursued and extensive references to related work are provided. 相似文献

Allan Franklin has identified a number of strategies that scientists use to build confidence in experimental results. This paper shows that Franklin’s strategies have direct analogues in the context of computer simulation and then suggests that one of his strategies—the so‐called ‘Sherlock Holmes’ strategy—deserves a privileged place within the epistemologies of experiment and simulation. In particular, it is argued that while the successful application of even several of Franklin’s other strategies (or their analogues in simulation) may not be sufficient for justified belief in results, the successful application of a slightly elaborated version of the Sherlock Holmes strategy is sufficient. 相似文献

An experimental analysis was conducted to determine the effects of involvement, commentator framing, and gender on viewer
attitudes toward female athletes. The sample was comprised of 112 students at a mid-western university in the United States.
Hypotheses and research questions were tested through a 2 × 3 multivariate analysis of covariance (MANCOVA). Results indicated
the overall MANCOVA was significant. Involvement was positively related to viewer attitudes’ towards the dependent variables
and explained 27.8% of the variance. Gender explained 39.3% of the variance in attitudes as male viewers had significantly
lower mean scores on all dependent variables. Male viewers had significantly lower scores than female viewers in the positive
framing condition; the interaction explained 8% of the variance in viewers’ perceptions of respectability of female athletes. 相似文献

A scaling analysis of the snake lightness illusion 总被引:1,自引:0,他引:1
Logvinenko and Maloney (2006) measured perceived dissimilarities between achromatic surfaces placed in two scenes illuminated by neutral lights that could differ in intensity. Using a novel scaling method, they found that dissimilarities between light surface pairs could be represented as a weighted linear combination of two dimensions, "surface lightness" (a perceptual correlate of the difference in the logarithm of surface albedo) and "surface brightness" (which corresponded to the differences of the logarithms of light intensity across the scenes). Here we attempt to measure the contributions of these dimensions to a compelling lightness illusion (the "snake illusion"). It is commonly assumed that this illusion is a result of erroneous segmentation of the snake pattern into regions of unequal illumination. We find that the illusory shift in the snake pattern occurs along the surface lightness dimension, with no contribution from surface brightness. Thus, even if an erroneous segmentation of the snake pattern into strips of unequal illumination does happen, it reveals itself, paradoxically, as illusory changes in surface lightness rather than as surface brightness. We conjecture that the illusion strength depends on the balance between two groups of illumination cues signaling the true (uniform) illumination and the pictorial (uneven) illumination. 相似文献

Humans are experts at familiar face recognition, but poor at unfamiliar face recognition. Familiarity is created when a face is encountered across varied conditions, but the way in which a person’s appearance varies is identity-specific, so familiarity with one identity does not benefit recognition of other individuals. However, the faces of biological siblings share structural similarities, so we explored whether the benefits of familiarity are shared across siblings. Results show that familiarity with one half of a sibling pair improves kin detection (experiment 1), and that unfamiliar face matching is more accurate when targets are the siblings of familiar versus unfamiliar individuals (experiment 2). PCA applied to facial images of celebrities and their siblings demonstrates that faces are generally better reconstructed in the principal components of a same-sex sibling than those of an unrelated individual. When we encounter the unfamiliar sibling of someone we already know, our pre-existing representation of their familiar relation may usefully inform processing of the unfamiliar face. This can benefit both kin detection and identity processing, but the benefits are constrained by the degree to which facial variability is shared. 相似文献

Cued-recall in episodic memory was investigated in relation to low and high cognitive support at retrieval, executive function level and fluid intelligence level in 81 healthy adults divided first into two age groups (young and elderly adults). The first analyses showed that age-related differences were greater when a low cognitive support was provided to recall the words. An individual index of loss of performance when the number of cues was decreased was then calculated. Hierarchical regression analysis revealed that the executive functions measure (perseverative errors on the Wisconsin Card Sorting Test) was a better candidate than the fluid intelligence measure (Cattell's culture fair test) to account for the age-related variance of the size of performance loss. These findings suggest that age differences in implementing strategic retrieval may be mainly due to a decline in executive functions. 相似文献
