Even when people perform tasks poorly, they often report unrealistically positive estimates of their own abilities in these situations. To better understand the origins of such overconfidence, we investigated whether it could be predicted by individual differences in working memory, attentional control, and self-reported trait impulsivity. Overconfidence was estimated by contrasting objective and subjective measures of situation awareness (the ability to perceive and understand task-relevant information in the environment), acquired during a challenging air traffic control simulation. We found no significant relationships between overconfidence and either working memory or attentional control. However, increased impulsivity significantly predicted greater overconfidence. In addition, overall levels of overconfidence were lower in our complex task than in previous studies that used less-complex lab-based tasks. Our results suggest that overconfidence may not be linked to high-level cognitive abilities, but that dynamic tasks with frequent opportunities for performance feedback may reduce misconceptions about personal performance. 相似文献

When developing ordinal rating scales, we may include potentially unordered response options such as “Neither Agree nor Disagree,” “Neutral,” “Don’t Know,” “No Opinion,” or “Hard to Say.” To handle responses to a mixture of ordered and unordered options, Huggins-Manley et al. (2018) proposed a class of semi-ordered models under the unidimensional item response theory framework. This study extends the concept of semi-ordered models into the area of diagnostic classification models. Specifically, we propose a flexible framework of semi-ordered DCMs that accommodates most earlier DCMs and allows for analyzing the relationship between those potentially unordered responses and the measured traits. Results from an operational study and two simulation studies show that the proposed framework can incorporate both ordered and non-ordered responses into the estimation of the latent traits and thus provide useful information about both the items and the respondents. 相似文献

基于目前广泛应用的动物实验伦理3R和5F原则,通过深入分析已有运动干预文献中的动物运动模型构建方法,分别就运动模型建立前实验动物的选取,运动模式、运动剂量的确定,模型建立过程中不同阶段不同运动形式所涉及的伦理问题,以及实验动物安乐死等各个方面进行伦理分析,探讨伦理关怀在动物运动模型建立中的必要性和重要性。运动模型的构建作为研究运动干预的关键环节是极其重要的,此建立过程中涉及到诸多动物实验伦理问题。

生态只是影响生命和健康的因素之一,而非全部;生态有其明确的范围,不能无限扩大;生物医学是整个医学的基础;生态医学要成为科学,必须植根于生物医学的基础;生态医学很难成为一种独立的医学模式,只能是生物心理社会医学模式的补充,理想的医学模式应当是生物心理社会生态医学模式;探索生态是如何影响生命与健康,如何应对生态之于生命与健康的影响,如何调整医学理念,是生态医学面临的三项任务。 相似文献

梳理了国外医患关系的相关文献,基于社会交换理论视角探析医患关系的内涵,深入剖析了医疗质量和患者信任是构成医患关系的两个重要因子,并进一步构建了简约化的四类医患关系模式,即和谐医患关系模式、改善医患关系模式、不善医患关系模式和紧张医患关系模式。认为医患关系的建立是一个动态的过程,在诊疗过程中医患关系模式之间是可以相互转换的,患者信任是构建和谐医患关系的基础,为我国和谐医患关系的建立进行了理论上的探索。 相似文献

The Necker-Zeno model of bistable perception provides a formal relation between the average duration of meta-stable percepts (dwell times T) of ambiguous figures and two other basic time scales (t0, ΔT) underlying cognitive processing. The model predicts that dwell times T covary with t0, ΔT or both. We tested this prediction by exploiting that observers, in particular experienced meditators, can volitionally control dwell times T.Meditators and non-meditators observed bistable Necker cubes either passively or tried to hold their current percept. The latencies of a centro-parietal event-related potential (CPP) were recorded as a physiological correlate of t0.Dwell times T and the CPP latencies, correlated with t0, differed between conditions and observer groups, while ΔT remained constant in the range predicted by the model. The covariation of CPP latencies and dwell times, as well as their quadratic functional dependence extends previous psychophysical confirmation of the Necker-Zeno model to psychophysiological measures. 相似文献

Working memory has long been thought to be closely related to consciousness. However, recent empirical studies show that unconscious content may be maintained within working memory and that complex cognitive computations may be performed on-line. This promotes research on the exact relationships between consciousness and working memory. Current evidence for working memory being a conscious as well as an unconscious process is reviewed. Consciousness is shown to be considered a subset of working memory by major current theories of working memory. Evidence for unconscious elements in working memory is shown to come from visual masking and attentional blink paradigms, and from the studies of implicit working memory. It is concluded that more research is needed to explicate the relationship between consciousness and working memory. Future research directions regarding the relationship between consciousness and working memory are discussed. 相似文献
