Many fields of study have shown that group discussion generally improves reasoning performance for a wide range of tasks. This article shows that most of the population, including specialists, does not expect group discussion to be as beneficial as it is. Six studies asked participants to solve a standard reasoning problem—the Wason selection task—and to estimate the performance of individuals working alone and in groups. We tested samples of U.S., Indian, and Japanese participants, European managers, and psychologists of reasoning. Every sample underestimated the improvement yielded by group discussion. They did so even after they had been explained the correct answer, or after they had had to solve the problem in groups. These mistaken intuitions could prevent individuals from making the best of institutions that rely on group discussion, from collaborative learning and work teams to deliberative assemblies. 相似文献

This study analyses the extent to which dispositional pessimists differ from defensive pessimists and optimists in the generation of prefactual and counterfactual thoughts and in their performance in an anagram task, under different conditions of induced mood. Dispositional pessimists performed in a similar manner in all circumstances, recording an equal number of prefactual thoughts. By contrast, optimists and defensive pessimists optimised their performance under positive and negative conditions, respectively. It should be noted that after performing this task, the number of counterfactual thoughts expressed by dispositional pessimists varied according to mood states. The results are discussed in terms of the rigidity of the generalised expectations of dispositional pessimism. 相似文献

Both future orientation and impulsivity are intrinsic parts of an adolescent’s self-control, and empirical evidence clearly establishes them as crucial features on the origin of juvenile deviant behavior. However, we do not yet fully understand how these variables relate in explaining deviant conduct. In the present study, we tested a mediation model between these variables among 126 Portuguese adolescents. Findings support the mediation model in analysis, namely that impulsivity fully mediates the effect of future orientation on deviant behavior. In conclusion, our results suggest that lesser future orientated youth develop impulsive behavior which, in turn, explains their higher deviant conduct. 相似文献

Heart rate recovery after 1 min of exercise cessation (HRR-1) is an important prognostic factor in patients with cardiovascular disease (CVD). We aimed to further elucidate the association between HRR-1 and known psychosocial risk factors in patients referred for comprehensive cardiac rehabilitation. We examined 521 patients with coronary heart disease in the first week of an outpatient cardiac rehabilitation program. Depressive and anxiety symptoms were measured with the Hospital Anxiety and Depression Scale, and positive (PA) and negative affect were rated with the Global Mood Scale. Depressive symptoms showed a significant inverse relationship with HRR-1 (p?<?.05), controlling for sociodemographic and medical covariates, whereas anxiety symptoms did not show a significant association. PA made a significant contribution to HRR-1 as well (p?<?.05). Our findings suggest an independent association between HRR-1 and psychosocial risk factors of CVD. 相似文献

The Pigeonhole Principle states that if n items are sorted into m categories and if n > m, then at least one category must contain more than one item. For instance, if 22 pigeons are put into 17 pigeonholes, at least one pigeonhole must contain more than one pigeon. This principle seems intuitive, yet when told about a city with 220,000 inhabitants none of whom has more than 170,000 hairs on their head, many people think that it is merely likely that two inhabitants have the exact same number of hair. This failure to apply the Pigeonhole Principle might be due to the large numbers used, or to the cardinal rather than nominal presentation of these numbers. We show that performance improved both when the numbers are presented nominally, and when they are small, albeit less so. We discuss potential interpretations of these results in terms of intuition and reasoning. 相似文献

The 'other-race' effect describes the phenomenon in which faces are difficult to distinguish from one another if they belong to an ethnic or racial group to which the observer has had little exposure. Adult observers typically display multiple forms of recognition error for other-race faces, and infants exhibit behavioral evidence of a developing other-race effect at about 9 months of age. The neural correlates of the adult other-race effect have been identified using ERPs and fMRI, but the effects of racial category on infants' neural response to face stimuli have to date not been described. We examine two distinct components of the infant ERP response to human faces and demonstrate through the use of computer-generated 'hybrid' faces that the observed other-race effect is not the result of low-level sensitivity to 3D shape and color differences between the stimuli. Rather, differential processing depends critically on the joint encoding of race-specific features. 相似文献

Chronic stress increases the risk of health problems and absenteeism, with negative consequences for individuals, organizations and society. The aim of the present study was to examine the effect of a brief stress management intervention based on the principles of Acceptance and Commitment Therapy (ACT) on stress and general mental health for Swedish social workers (n = 106) in a randomized, controlled trial. Participants were stratified according to stress level at baseline in order to examine whether initial stress level moderated the effect of the intervention. Two thirds of the participants had high stress levels at baseline (Perceived Stress Scale; score of ≥ 25). The results showed that the intervention significantly decreased levels of stress and burnout, and increased general mental health compared to a waiting list control. No statistically significant effects were, however, found for those with low levels of stress at baseline. Among participants with high stress, a substantial proportion (42%) reached criteria for clinically significant change. We concluded that the intervention successfully decreased stress and symptoms of burnout, and increased general mental health. Evidence is, thus, provided supporting ACT as brief, stress management intervention for social workers. 相似文献

This article gives a didactic introduction to the analysis of multitrait-multimethod data with models of multilevel confirmatory factor analysis. In particular, the principles of the multilevel CT-C(M-1) model for interchangeable and structural different methods are explained in detail, and the first application of this model to more than two structurally different methods is presented. The model is illustrated by an application to the analysis of the convergent and discriminant validity of the trait subscales of the State-Trait Cheerfulness Inventory (STCI-T, Ruch, Köhler, & van Thriel, 1996). The results show that the STCI is a reliable and valid questionnaire for assessing the temperamental basis of sense of humor. 相似文献

In the present study we examined the neural correlates of facial emotion processing in the first year of life using ERP measures and cortical source analysis. EEG data were collected cross‐sectionally from 5‐ (N = 49), 7‐ (N = 50), and 12‐month‐old (N = 51) infants while they were viewing images of angry, fearful, and happy faces. The N290 component was found to be larger in amplitude in response to fearful and happy than angry faces in all posterior clusters and showed largest response to fear than the other two emotions only over the right occipital area. The P400 and Nc components were found to be larger in amplitude in response to angry than happy and fearful faces over central and frontal scalp. Cortical source analysis of the N290 component revealed greater cortical activation in the right fusiform face area in response to fearful faces. This effect started to emerge at 5 months and became well established at 7 months, but it disappeared at 12 months. The P400 and Nc components were primarily localized to the PCC/Precuneus where heightened responses to angry faces were observed. The current results suggest the detection of a fearful face in infants’ brain can happen shortly (~200–290 ms) after the stimulus onset, and this process may rely on the face network and develop substantially between 5 to 7 months of age. The current findings also suggest the differential processing of angry faces occurred later in the P400/Nc time window, which recruits the PCC/Precuneus and is associated with the allocation of infants’ attention. 相似文献
