Employees of a corporation who had undergone considerable training for effective teamwork were asked to brainstorm about a job-relevant issue in groups of four or alone. One half of the groups brainstormed alone first, and the other half brainstormed as a group before brainstorming alone. Participants were also asked to rate their performance and indicate whether they would perform better in groups or alone on a brainstorming task. Consistent with past laboratory research, groups generated only about half as many ideas as a similar number of individuals (nominal group), and group brainstorming led to more favorable perceptions of individual performance. Participants also believed that they would brainstorm more effectively in a group than alone. These results indicate that productivity losses in brainstorming groups are not restricted to laboratory groups. Such losses occur even in groups who work together on a daily basis, have considerable training in group dynamics, and are dealing with a job-relevant issue. The sequence of alone to group brainstorming did not influence overall productivity. The relation of this research to that of facilitated and electronic brainstorming is discussed. 相似文献

Over the years, people have searched for deception cues in the liar's behavior. However, the sender's incentives to lie might be more revealing than behavior. In Experiment 1, an incentive was developed that was predictive of lying. Judges with access to incentive information in addition to behavior achieved almost perfect lie/truth detection. This was not a result of the speakers' behavior being transparent (Experiment 2) but because incentive information was useful to separate lies from truths (Experiments 2 and 3). Experiment 3 revealed that people may forego perfectly diagnostic contextual cues to base their judgments on illusory behavioral cues. 相似文献

Much of what we need to plan for our survival is already known, but what we know, how we know, and who knows is divided up between disciplines. Thus much of the problem of ensuring our survival is a matter of learning across the disciplines. We identify four modes through which we bring disciplinary knowledge together: the unity of science, integrated assessment, heuristic models, and distributed learning networks. Although none of them are perfect, we can learn how to put our knowledge together across the disciplines much better than we do. 相似文献

Three aspects of electronic communications technology are described: convergence of modes, communities of interest, and impacts on culture. Nine recurring aspects of technology and its use, which are particularly pertinent to our time, are discussed. 相似文献

The present system of politics is based on the centrality of economics. This system is not capable of coming to grips with the problems confronting humanity. A culture-based system of politics is required to do this and prevent ecological disaster. This system would make it possible to reduce the demands human beings are making on the natural environment and situate human welfare, environmental well-being, and the public interest at the core of the political process. The risks of such a system could be reduced through cultural education and improved cultural understanding. 相似文献

The present study investigated the effect of haloperidol-induced mood in normal healthy male volunteers on the retrieval of memories of real-life personal experiences using a between-subjects double-blind design. Forty subjects were required to retrieve past real life experiences associated with a series of stimulus words following administration of a single oral dose of 5mg haloperidol or placebo. The experiences were subsequently rated by subjects for their happiness felt at the time of the original experience. A significant decline in self-reported hedonic tone was observed in subjects given haloperidol. In addition, subjects on placebo recalled a significantly greater percentage of happy memories than subjects who were on haloperidol; a trend for a reverse pattern was observed for unhappy memories. The effects of the drug on the retrieval of memories were only in part mediated by the decline in hedonic tone scores. The effects of haloperidol are interpreted in terms of drug-induced dysphoria. 相似文献

Two experiments tested the effect of exposure to masked phobic stimuli at a very brief stimulus onset asynchrony on reducing the subjective experience of fear caused by in vivo exposure to a feared object. In the main experiment, 35 spider-fearful and 35 non-fearful participants were identified with a questionnaire and a Behavioural Avoidance Test (BAT) with a live tarantula. One week later, they were individually administered one of two continuous series of masked images: spiders or flowers. They engaged in the BAT again immediately thereafter. They provided ratings of subjective fear at the end of each BAT (pre- and post-manipulation). Very brief exposure to images of spiders reduced the fearful group's and not the non-fearful group's experience of fear at the end of the BAT. This effect was replicated with another sample of 26 spider-fearful participants from the same population. Theoretical implications are discussed. 相似文献

Research has broadly established that emotional disturbances are associated with body image disturbances. This is the first study to examine links between facets of emotional awareness and peculiar body-related beliefs (PBB), or beliefs about an imagined or slight defect in one's appearance or bodily functioning. In a sample of college students (n=216), we found that low emotional clarity (the extent to which the type and source of emotions are understood) was associated with higher PBB in both women and men, and the relation between emotional clarity and PBB was further moderated by attention to emotions (the extent to which emotions are attended to) and gender. Men with low attention to emotions and women with high attention to emotions both experienced higher levels of PBB if they also reported low levels of emotional clarity. This interactive effect was not attributable to shared variance with body mass index, neuroticism or affect intensity. 相似文献

Positive events are more common (more tokens), but negative events are more differentiated (more types). These observations and asymmetries about the world are consistent with a number of features or biases favouring positive adjectives that have been shown for English. Compared to their opposites, positive adjectives in English are more likely to be unmarked, negated into their opposite, define the entire negative to positive dimension, and occur first in conjunctions with their negative opposite. In this paper we document that these biases have considerable generality, appearing in all or almost all of 20 natural languages. The greater differentiation of negative states is illustrated here by the demonstration that five common nouns describing negative states in English (disgust, risk, sympathy, accident, murderer) have equivalents in most or all of the 20 languages surveyed, but the opposite of these nouns is not lexicalised in most of the 20 languages. 相似文献

How does personality influence the relationship between appraisals and emotions? Recent research suggests individual differences in appraisal structures: people may differ in an emotion's appraisal pattern. We explored individual differences in interest's appraisal structure, assessed as the within-person covariance of appraisals with interest. People viewed images of abstract visual art and provided ratings of interest and of interest's appraisals (novelty–complexity and coping potential) for each picture. A multilevel mixture model found two between-person classes that reflected distinct within-person appraisal styles. For people in the larger class (68%), the novelty–complexity appraisal had a stronger effect on interest; for people in the smaller class (32%), the coping potential appraisal had a stronger effect. People in the larger class were significantly higher in appetitive traits related to novelty seeking (e.g., sensation seeking, openness to experience, and trait curiosity), suggesting that the appraisal classes have substantive meaning. We conclude by discussing the value of within-person mixture models for the study of personality and appraisal. 相似文献
