Children can solve Bayesian problems: the role of representation in mental computation 总被引:4,自引:0,他引:4
Can children reason the Bayesian way? We argue that the answer to this question depends on how numbers are represented, because a representation can do part of the computation. We test, for the first time, whether Bayesian reasoning can be elicited in children by means of natural frequencies. We show that when information was presented to fourth, fifth, and sixth graders in terms of probabilities, their ability to estimate the Bayesian posterior probability was zero. Yet when the same information was presented in natural frequencies, Bayesian reasoning showed a steady increase from fourth to sixth grade, reaching an average level of 19, 39, and 53%, respectively, in two studies. Sixth graders' performance with natural frequencies matched the performance of adults with probabilities. But this general increase was accompanied by striking individual differences. More than half of the sixth graders solved most or all problems, whereas one third could not solve a single one. An analysis of the children's responses provides evidence for the use of three non-Bayesian strategies. These follow an overlapping wave model of development and continue to be observed in the minds of adults. More so than adults' probabilistic reasoning, children's reasoning depends on a proper representation of information. 相似文献

论理学对中国“画气”说的影响 总被引:1,自引:0,他引:1
中国画学中以气论画的传统可以追溯到六朝时期,而真正形成具有丰富理论内涵的画气说则在两宋。画气说的形成具有明显的哲学背景,北宋以来的理学思潮是画气说形成的最直接因素。本文认为,理学对画学理论中气论的影响主要集中在三个方面,一是为画气说提供一个有机论的基础,在气机哲学的影响下,中国画学将表现对象活泼生机作为根本目的,这突出体现在山水画和花鸟画中;二是从审美体验角度,中国画学形成了“以气合气”的独特创作思想;三是在绘画艺术形式上,气势论成为一引人注意的理论,六朝时的气韵生动理论获得了新的发展。 相似文献

中文阅读及发展性阅读障碍眼动研究新进展 总被引:1,自引:0,他引:1
中文阅读眼动特征的评估参数主要包括注视点停留位置、眼跳、回视和注视时间等。基于眼动技术,并结合生理技术,研究者已揭示出正常读者中文阅读的多方面特点和规律。但对发展性阅读障碍的眼动研究,国内还没有开展起来。从上述两个角度出发,这里总结了正常读者中文阅读的眼动研究,并探讨了发展性阅读障碍者的眼动特征及机制。 相似文献

During the COVID-19 pandemic, pregnant women, especially those from socioeconomically disadvantaged and marginalized groups, experienced unprecedented stress. Prenatal stress and social determinants of health (SDoH) such as lower education and lack of a relationship partner are known to contribute to earlier birth. However, whether SDoH and stress independently contribute or whether the harmful impact of SDoH is mediated by stress is unknown. Moreover, the contributions of these factors has not been investigated in the context of a communal health crisis such as the COVID-19 pandemic. To examine these processes, we used a longitudinal cohort of 2473 women pregnant during the COVID-19 pandemic who reported a live birth. We compared structural equation models predicting gestational age at birth from SDoH (race/ethnicity, education, financial security, health insurance, relationship status, and lifetime abuse) and from prenatal maternal stress related and unrelated to the COVID-19 pandemic. Results indicate that the association of SDoH with earlier birth was partially mediated by prenatal stress. These findings help uncover mechanisms explaining health disparities in the U.S. and highlight the need to address both SDoH and the stress that these factors produce in under-resourced and marginalized communities. 相似文献

Although men are substantially more interested than women in casual sex, there is ample variation in this trait (sociosexuality) within both sexes. One theory hypothesizes that within-sex sociosexual variation results from genetic variation maintained by frequency-dependent selection. If so, sociosexuality should be substantially heritable. A competing theory is that children acquire their mating strategy after observing their parents' relationship. By this theory, sociosexuality should reveal a strong shared environmental component. The authors studied genetic and environmental influences on sociosexuality using a large, representative volunteer twin sample. Parental marital instability was modestly associated with sociosexuality, but this could have been due to either genetic or environmental factors. Consistent with genetic theory, familial resemblance appeared primarily due to additive genetic rather than shared environmental factors. 相似文献

Food-related attentional bias refers that individuals typically prioritize rewarding food-related cues (e.g. food words and food images) compared with non-food stimuli; however, the findings are inconsistent for restrained eaters. Traditional paradigms used to test food-related attentional bias, such as visual probe tasks and visual search tasks, may not directly and accurately enough to reflect individuals' food-word processing at different cognitive stages. In this study, we introduced the boundary paradigm to investigate food-word attentional bias for both restrained and unrestrained eaters. Eye movements were recorded when they performed a naturalistic sentence-reading task. The results of later-stage analyses showed that food words were fixated on for less time than non-food words, which indicated a superiority of foveal food-word processing for both restrained and unrestrained eaters. The results of early-stage analyses showed that restrained eaters spent more time on pre-target regions in the food-word valid preview conditions, which indicated a parafoveal food-word processing superiority for restrained eaters (i.e. the parafoveal-on-foveal effect). The superiority of foveal food-word processing provides new insights into explaining food-related attentional bias in general groups. Additionally, the enhanced food-word attentional bias in parafoveal processing for restrained eaters illustrates the importance of individual characteristics in studying word recognition. 相似文献

心智架构或认知架构是指一个功能相对完整的认知系统的基本组织结构。经典认知科学的理论或模型大多采纳了某种类似于冯·诺依曼式计算机体系结构的心智架构,即认知系统由一些各司其职的心理模块与一个负责整合与协调的中枢部门所构成。进化心理学的众量模块性论题对经典认知科学的心智架构观提出了严厉挑战,并引发了许多争议。本文提出认知冲突协调问题是任何一个足够复杂的认知系统均需要处理的基本问题,并以此来审视关于心智架构的论战,指出此问题对众量模块性论题构成了严重的困难。 相似文献

More attention is being given to the stable, dispositional tendency to maximize when making decisions. Within the growing body of research has been an exchange regarding the appropriate means of measuring maximizing tendency. Guided primarily by psychometric and statistical analyses, these studies have critiqued and revised existing maximizing tendency scales and/or introduced new measures. Importantly, many of these discussions seem to ignore theoretical considerations of the construct of maximizing. In this article, we revisit the original work of Herbert Simon, from where the theory of maximizing tendency was developed, and provide a theoretical account for how maximizers can be distinguished from satisficers and the implications therein for the measurement of maximizing tendency. Across two studies, we provide an updated psychometric, correlational, and behavioral comparison of the two most popular maximizing tendency scales: the Maximization Scale and the Maximizing Tendency Scale. Results demonstrate that the Maximizing Tendency Scale is more theoretically and psychometrically valid than the Maximization Scale. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Using the data from the China Household Finance Survey in 2011, we study the relation between happiness and stockholding. We find that a household’s propensity of investing in stocks or mutual funds, as well as household asset shares invested in stocks or mutual funds, is strongly associated with happiness. Moreover, empirical results suggest that among the three potential channels we propose, the association between happiness and stockholding is driven by trust (or social capital), rather than households’ risk preference or optimism level. 相似文献
