用大学生被试的两个实验考察人们对两个原因交互作用效应的定性评估和定量评估。实验结果表明,被试的定性评估与交互作用对比的性质相一致,而与因果力的性质不相一致;被试的定量评估随交互作用对比值增加而增加,而不受因果力的影响。实验结果一致支持交互作用对比标准,而不支持因果力标准和交叉乘积比率标准。这不同于以往的有关研究结果 相似文献

Summary This is a sequel to my paper, “Searching for a (Post)Foundational Approach to Philosophy of Science”, which appeared in an
earlier issue of this Journal [Ginev 2001, Journal for General Philosophy of science
32, 27–37]. In the present paper I continue to scrutinize the possibility of a strong hermeneutics of scientific research. My
aim is to defend the position of cognitive existentialism that combines the advocacy of science’s cognitive specificity and the rejection of any form of essentialism. A special attention
will be paid to the notion of the thematizing project of scientific research. 相似文献

该研究采用问卷法,以481名中学生为被试,通过无约束结构方程模型分析方法探讨了外向性、宜人性人格特征与互联网服务偏好的交互作用对网络成瘾的影响。研究发现在对网络成瘾的影响上,青少年宜人性人格特征与互联网社交服务偏好存在显著的交互作用,但与互联网娱乐、信息和交易服务偏好的交互作用不显著。外向性人格特征与互联服务偏好不存在显著的交互作用。(1)从平均影响来看,外向性、宜人性、互联网社交、娱乐和交易使用偏好能够正向预测网络成瘾,互联网信息使用偏好对网络成瘾没有显著的预测效果;(2)在宜人性高分组中,互联网社交服务偏好与PIU的正向关系要强于宜人性低分组。斜率检验表明对于低宜人性人格的青少年来说,互联网社交服务偏好不易导致其成瘾,而对高宜人性人格的青少年而言,互联网社交服务偏好反而容易导致其成瘾。 相似文献

探讨平板运动试验(TET)结合颈动脉斑块检测在诊断冠心病的临床意义。对166例疑诊冠心病患者进行冠状动脉造影(CAG),TET,颈动脉斑块检查,以CAG的诊断结果为金标准,分析TET,颈动脉斑块检查,TET结合颈动脉斑块检查诊断冠心病的敏感度、特异度。比较三者诊断冠心病的敏感度、特异度。三者敏感度分别为71.4%、64.3%、96.0%。特异度分别为65%、60.0%、82.4%。后者较前两者敏感度、特异度P<0.05。TET结合颈动脉斑块检查可显著提高冠心病的诊断率,不失为CAG前的筛选方法。 相似文献

Before alcohol was generally known to cause birth defects, NIAAA in 1974 began funding a population-based Seattle study on
alcohol use and pregnancy outcome. Women receiving prenatal care by mid-pregnancy were recruited (N = 1,529) and interviewed at home. Approximately 500 offspring exposed to a range of alcohol levels were examined on 11 occasions
between day 1 and 25 years. Neuropsychological and neurobehavioral performance measures are correlated with prenatal alcohol
dose, without substantial confounding by socio-demographic or rearing conditions, smoking, nutrition, or other drugs. Deficits
in attention, arithmetic skill, spatial-visual memory, and IQ, as well as increased alcohol problems and psychiatric disorders
are among offspring outcomes correlated at several ages with maternal drinking during and before pregnancy recognition. Findings
are not confined to women who believed they had alcohol problems. Not all exposed offspring appear affected. 相似文献

Effects of classroom context on university students’ judgments about cheating: mediating and moderating processes 总被引:2,自引:1,他引:1

Hypothetical vignettes were used to examine the effects of classroom context variables (pedagogical quality and classroom
goal structure) on undergraduate (study 1) and graduate (study 2) students’ judgments about cheating. Consistent with attribution
theory and previous findings, poor (versus good) pedagogy and performance (versus mastery) goals structures resulted in more
teacher blame and less student blame for cheating, and cheating was rated as more acceptable and more likely in these situations.
Participants’ own prior cheating history but not their experience as a classroom teacher also affected these judgments. Relations
between classroom context variables and assigned blame for cheating were mediated by students’ assessments of the fairness
of the classroom situation. 相似文献

Children and adults commonly produce more generic noun phrases (e.g., birds fly) about animals than artifacts. This may reflect differences in participants’ generic knowledge about specific animals/artifacts (e.g., dogs/chairs), or it may reflect a more general distinction. To test this, the current experiments asked adults and preschoolers to generate properties about novel animals and artifacts (Experiment 1: real animals/artifacts; Experiments 2 and 3: matched pairs of maximally similar, novel animals/artifacts). Data demonstrate that even without prior knowledge about these items, the likelihood of producing a generic is significantly greater for animals than artifacts. These results leave open the question of whether this pattern is the product of experience and learned associations or instead a set of early-developing theories about animals and artifacts. 相似文献

Using a name-based categorization task, Nazzi found in 2005 that French-learning 20-month-olds can make use of one-feature consonantal contrasts between new labels but fail to do so with one-feature vocalic contrasts. This asymmetry was interpreted as developmental evidence for the proposal that consonants play a more important role than vowels at the lexical level. In the current study using the same task, we first show that by 30 months French-learning infants can make use of one-feature vocalic contrasts (e.g., /pize/–/pyze/). Second, we show that in a situation where infants must neglect either a consonantal one-feature change or a vocalic one-feature change (e.g., match a /pide/ with either a /tide/ or a /pyde/), both French- and English-learning 30-month-olds choose to neglect the vocalic change rather than the consonantal change. We argue that these results suggest that by 30 months of age, infants still give less weight to vocalic information than to consonantal information in a lexically related task even though they are able to process fine vocalic information. 相似文献
