We examine the notion of conditionals and the role of conditionals in inductive logics and arguments. We identify three mistakes commonly made in the study of, or motivation for, non-classical logics. A nonmonotonic consequence relation based on evidential probability is formulated. With respect to this acceptance relation some rules of inference of System P are unsound, and we propose refinements that hold in our framework. 相似文献

Fifty items from Goldberg's International Personality Item Pool were compiled to form a public‐domain measure of personality, the Australian Personality Inventory (API). Data from a random community sample (N = 7615) and a university‐based sample (N = 271) were used to explore psychometric properties of this 50‐item measure of the five‐factor model of personality (FFM). In both samples, internal reliabilities were adequate. In the university‐based sample an appropriate pattern of convergent and divergent relationship was found between scale scores and domain scores from the NEO Five‐Factor Inventory. After adjusting for an apparent response set (mean response across items), exploratory factor analyses clearly retrieved the FFM in both samples. It is provisionally concluded that raw scale scores from the API provide reliable estimates of the FFM, but adjustment for mean response across the 50 items might clarify the five‐factor structure, especially in less educated samples. 相似文献

The present studies compare young children’s explanations and predictions for the biological phenomenon of contamination. In Study 1, 36 preschoolers and 24 adults heard vignettes concerning contamination, and were asked either to make a prediction or to provide an explanation. Even 3-year-olds readily supplied contamination-based explanations, and most children mentioned an unseen mechanism (germs, contact through bodily fluids). Moreover, unlike adults who performed at ceiling across both explanation and prediction tasks, children were significantly more accurate with their explanations than their predictions. In Study 2, we varied the strength of cues regarding the desirability of the contaminated substance (N = 24 preschoolers). Although desirability affected responses, for both levels of desirability participants were significantly more accurate on explanation than prediction questions. Altogether, these studies demonstrate a significant “explanation advantage” for children’s reasoning in the domain of everyday biology. 相似文献

Paul B. Baltes于1981年在马普人类发展研究所成立的毕生发展心理研究中心已经使毕生发展心理学成为了发展心理学中的一个重要的概念分支。2004年以来,中心已经将研究项目扩展到了发展行为神经科学。中心主要在三个主题上开展研究工作: (1) 研究作为成熟、学习和衰老的交互作用的结果, 毕生的不同发展阶段中人类行为变化的规律: (2) 发展能够整合来自于自身机能、时间序列、以及行为和神经层面分析等领域实证证据的理论和方法体系。(3) 通过探索不同年龄可塑性上的差异寻找发展的机制。中心继续重点关注成人晚期和老年期, 这为理论和实践上的创新提供了独特的机遇。同时, 中心加强了对包括婴儿期和儿童早期在内的个体发展早期阶段的研究。本文报告了来自四项从行为和神经层面分析感觉和认知发展的研究的最新发现。 相似文献

This study examined whether prevalence information promotes children's false memories for an implausible event. Forty‐four 7–8 and forty‐seven 11–12 year old children heard a true narrative about their first school day and a false narrative about either an implausible event (abducted by a UFO) or a plausible event (almost choking on a candy). Moreover, half of the children in each condition received prevalence information in the form of a false newspaper article while listening to the narratives. Across two interviews, children were asked to report everything they remembered about the events. In both age groups, plausible and implausible events were equally likely to give rise to false memories. Prevalence information increased the number of false memories in 7–8 year olds, but not in 11–12 year olds at Interview 1. Our findings demonstrate that young children can easily develop false memories of a highly implausible event. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

ABSTRACT— Three studies were conducted to examine the often-cited conclusion that human females are more sociable than males. Using perceptions of roommates, roommate changes at three collegiate institutions, and an experimental manipulation of friendship beliefs, the studies demonstrated unequivocally that males exhibit a higher threshold of tolerance for genetically unrelated same-sex individuals than females do. Tolerance was defined as acceptance of the stresses and strains within relationships. Results are discussed in terms of potential underlying mechanisms and ultimate explanations. 相似文献

ABSTRACT— At what age do infants understand that goals exist independently of the actions that result from them? Exploring infants' understanding of failed intentional actions—when the goal of the action is unfulfilled and thus not apparent in the actor's movements—is a critical step in answering this question. Using a visual habituation paradigm, we assessed when infants understand that a failed intentional action is goal directed and whether an understanding of successful intentional actions (actions that do overtly attain their goals) precedes an understanding of failed intentional actions. Results demonstrated that 10- and 12-month-olds recognized the goal directedness of both successful and failed reaching actions. Eight-month-olds also recognized the goal directedness of successful actions, but not of unsuccessful attempts. Thus, by the end of the 1st year of life, infants possess an impressive understanding of intentional action, and an understanding of failed intentional actions follows an earlier understanding of successful ones. 相似文献

ABSTRACT— Popular history films sometimes contain major historical inaccuracies. Two experiments investigated how watching such films influences people's ability to remember associated texts. Subjects watched film clips and studied texts about various historical topics. Whereas the texts contained only correct information, the film clips contained both correct information (consistent with the text) and misinformation (contradicted by the text). Before watching each clip, subjects received a specific warning, a general warning, or no warning about the misinformation. One week later, they returned for a cued-recall test about the texts. Watching a film clip increased correct recall of consistent information relative to recall of the same information when subjects did not see the clip. However, when the information in the film contradicted the text, subjects often (falsely) recalled misinformation from the film. The specific warning substantially reduced this misinformation effect. Teachers should use popular history films with caution and should warn students about major inaccuracies in the films. 相似文献
