Griffin and Tversky (1992) explain evidence of individual over- and underconfidence as resulting from attending too much to the strength (i.e., extremity) of information and not enough to the weight (i.e., statistical reliability) of information. We report two experiments that demonstrate how information strength and weight affect confidence, trading, prices, and wealth in laboratory markets. Our results indicate that information strength and weight affect individual over- and underconfidence and that market participants lack sufficient self-insight to avoid trading when they are biased. As a consequence, market prices are biased, and market participants with high-strength, low-weight information systematically transfer wealth to participants with low-strength, high-weight information. 相似文献

PurposeTo evaluate the effects of demographics and hormonal variations on knee muscle performance in patients with acromegaly and develop explanatory models of peripheral muscle function in these individuals.MethodsThis was a cross-sectional study in which 53 acromegalics and 27 healthy subjects underwent knee isokinetic dynamometry to evaluate the peak torque value for leg extension at 75°/s (PTE75) and 240°/s (PTE240). Separate multivariable linear regression models for the prediction of PTE75 and PTE240 were tested using variables commonly used as predictors in the clinical setting and other specific variables related to acromegaly.ResultsThe final prediction model for PTE75 (R2 = 0.888; adjusted R2 = 0.820, SE of bias = 16.2 Nm, p < 0.001) was −0.221 × growth hormone + 36.791 × sexmale = 1 − 27.407 × statusactive = 1 − 0.690 × age + 148.071. The final prediction model for PTE240 (R2 = 0.816; adjusted R2 = 0.805, SE of bias = 8.8 Nm, p < 0.001) was −0.174 × growth hormone + 12.522 × sexmale = 1 − 0.520 × age + 98.099.ConclusionsIn acromegalics, high growth hormone levels, female gender, and older age are associated with reduced muscle strength and endurance. Additionally, active disease negatively affects peripheral muscle strength in these patients. 相似文献

Theory-based interventions can enhance people’s safe water consumption, but the sustainability of these interventions and the mechanisms of maintenance remain unclear. We investigated these questions based on an extended theory of planned behaviour. Seven hundred and ten (445 analysed) randomly selected households participated in two cluster-randomised controlled trials in Bangladesh. Study 1 promoted switching to neighbours’ arsenic-safe wells, and Study 2 promoted switching to arsenic-safe deep wells. Both studies included two intervention phases. Structured interviews were conducted at baseline (T1), and at 1-month (T2), 2-month (T3) and 9-month (T4) follow-ups. In intervention phase 1 (between T1 and T2), commitment-based behaviour change techniques – reminders, implementation intentions and public commitment – were combined with information and compared to an information-only control group. In phase 2 (between T2 and T3), half of each phase 1 intervention group was randomly assigned to receive either commitment-based techniques once more or coping planning with reminders and information. Initial well-switching rates of up to 60% significantly declined by T4: 38.3% of T2 safe water users stopped consuming arsenic-safe water. The decline depended on the intervention. Perceived behavioural control, intentions, commitment strength and coping planning were associated with maintenance. In line with previous studies, the results indicate that commitment and reminders engender long-term behavioural change. 相似文献

Qualitative and quantitative models were proposed to understand the shear band (SB) interaction scenario found in the compressive tests on specimen with two symmetrical semi-circular notches. The so-called ‘work-hardening’ behavior could be ascribed as the stress interaction which was caused by stress fields around the SB tips. Besides, the SB bending was observed along propagation orientation. The quantitative analysis based on traditional shear deformation mechanism could reasonably account for how the SB was bent. It is anticipated that the present work could provide a pathway to understand the deep SB deformation mechanism of metallic glass. 相似文献

Transportation describes the degree to which individuals get absorbed in the fictional world of a story. Although conceived as a psychological state evoked by the processed narrative, it has also been associated with trait-like characteristics. An experimentally enhanced latent state–trait (LST) model was used to assess the degree to which transportation reflects (a) stable individual differences, and (b) systematic situational effects and/or person–situation interactions. After reading each of four stories 149 undergraduates rated their degree of being transported into the respective narratives. The contents of the stories were experimentally varied to (a) either facilitate or hinder transportation, and (b) present strong or weak arguments for the idea put forward in the stories. The LST analyses and experimental manipulations concordantly revealed that transportation captures pronounced situational effects related to the presented stories and to some degree also interindividual differences. In line with transportation theory, argument strength had no effect on the state component of transportation. 相似文献

Here we show that gender identification of male (but not female) heterosexual, right-handed dancers correlates with physical strength (measured via handgrip strength) after controlling for the effect of body-mass-index on strength. Using optical motion capture technology, we collected the dance movements of men and women for subsequent animations of uniform shape- and texture-standardized virtual characters (avatars). Short video clips (15 s) of these movements were presented to male and female adults and children, who were asked to identify the gender of the avatar. Gender identification performance was significantly higher than chance for both adults and children. Among adults (but not among children) the avatars of male dancers who were physically stronger were perceived as males significantly more often than were the avatars of male dancers who were physically weaker. There was no relationship between strength and gender identification for female dancers. We conclude that physical strength affects gender identification from human dance movements at least for male dancers, and that pre-pubertal children might not be sensitive to strength cues in dance movements. 相似文献

Children can selectively attend to various attributes of a model, such as past accuracy or physical strength, to guide their social learning. There is a debate regarding whether a relation exists between theory‐of‐mind skills and selective learning. We hypothesized that high performance on theory‐of‐mind tasks would predict preference for learning new words from accurate informants (an epistemic attribute), but not from physically strong informants (a non‐epistemic attribute). Three‐ and 4‐year‐olds (N = 65) completed two selective learning tasks, and their theory‐of‐mind abilities were assessed. As expected, performance on a theory‐of‐mind battery predicted children's preference to learn from more accurate informants but not from physically stronger informants. Results thus suggest that preschoolers with more advanced theory of mind have a better understanding of knowledge and apply that understanding to guide their selection of informants. This work has important implications for research on children's developing social cognition and early learning. 相似文献

A theory for the strength contribution from precipitates is developed based on the statistical particle-size and shape distributions and the corresponding obstacle strengths. The generic case of spherical precipitates and the special case of needle-shaped precipitates in the 6xxx aluminium alloy series are considered. It is accounted for that the largest precipitates are stronger and at the same time, intersect a larger number of slip planes than the smaller ones. For a considered peak aged AA6082, the improved model gives a 59% higher strength, which fits the experiments well without the need of previously introduced calibration parameter for the mean effective particle spacing in the slip plane. 相似文献

根据特征归纳的关联相似性模型分析和三个因素实验研究发现,在基于关联相似性而进行的特征归纳中,关联强度和关联相似性两因素对归纳强度的影响存在交互作用效应。关联相似性变化对归纳强度的影响依赖于关联强度,随关联强度的增加而增加。关联强度变化对归纳强度的影响依赖于关联相似性水平：在高的关联相似性条件下,归纳强度随关联强度增加而增加;在中等关联相似性条件下,归纳强度不受关联强度变化的影响;而在低的关联相似性条件下,归纳强度随关联强度增加而减小 相似文献

本研究采用3个实验考察编码强度对字体大小效应的影响,探讨由于知觉特征而引发的元认知错觉的内在产生机制(实验1)与有效的矫正措施(实验2和实验3)。结果发现:(1)大字体词语的知觉流畅性显著优于小字体,并且贝叶斯多层中介分析结果表明,知觉流畅性对字体大小效应起部分中介作用(实验1);(2)随着编码强度的增加,由字体大小引起的学习判断错觉逐渐消失(实验2和实验3)。以上结果表明,刺激的知觉特征(字体大小)对个体学习判断的影响,随编码强度激活线索的增加而逐渐减弱。这一结果为真实教学情境中提高学习者的编码强度,进而削弱学习判断对知觉特征线索的依赖,并准确地监测自身的学习进程提供了科学依据。 相似文献
