The paper reports on an investigation of the convergent and discriminant validity of Raven’s matrices in considering reasoning and spatial abilities. Raven’s advanced progressive matrices (APM) and four scales representing reasoning, visualization, mental rotation and closure were applied to a sample of N = 280 university students. The data were investigated by means of structural equation modeling. The results demonstrated convergent validity of APM with respect to reasoning. In contrast, in investigating discriminant validity substantial correlations of moderate size between APM and the scales representing spatial abilities were observed. However, the investigation of the structure of the prediction of APM revealed that the scales representing spatial abilities did not improve the prediction based on the reasoning scale alone at the latent level. Consequently, it is suggested that Raven’s matrices show good convergent validity and slightly impaired discriminant validity. 相似文献

We examined whether the implicit association test (IAT) could serve as an implicit measure of the dimensions of the Five-Factor Model of Personality. In the first study (N = 84) IAT-effects of the Big-Five (Extraversion, Agreeableness, Conscientiousness, Neuroticism and Openness) were found and the IAT showed good internal consistencies and convergent validity with an explicit Big-Five questionnaire (NEO-FFI-30). In a second study (N = 50), conducted to determine the overlap of the personality-IATs with implicit self-esteem, the Extraversion and the Neuroticism-IAT were shown to correlate with a self-esteem-IAT only moderately. 相似文献

Abstract: This study examined how a metacognitive strategy known as self‐explanation influences word problem solving in elementary school children. Participants were 79 sixth‐graders. They were assigned to one of three groups: the self‐explanation group, the self‐learning group, or the control group. Students in each group performed a ratio word problem test and a transfer test. The results showed that students in the self‐explanation group outperformed students in the other two groups on both the ratio word problem test and on the transfer test. In addition, high explainers who generated more self‐explanations relating to deep understanding of worked‐out examples outperformed low explainers on both ratio word problem and transfer tests. The self‐explanation effect is discussed. 相似文献

The ameliorating effect of oroxylin A on scopolamine-induced memory impairment in mice 总被引:2,自引:0,他引:2

Oroxylin A is a flavonoid and was originally isolated from the root of Scutellaria baicalensis Georgi., one of the most important medicinal herbs in traditional Chinese medicine. The aim of this study was to investigate the ameliorating effects of oroxylin A on memory impairment using the passive avoidance test, the Y-maze test, and the Morris water maze test in mice. Drug-induced amnesia was induced by administering scopolamine (1 mg/kg, i.p.) or diazepam (1 mg/kg, i.p.). Oroxylin A (5 mg/kg) significantly reversed cognitive impairments in mice by passive avoidance and the Y-maze testing (P<.05). Oroxylin A also improved escape latencies in training trials and increased swimming times and distances within the target zone of the Morris water maze (P<.05). Moreover, the ameliorating effects of oroxylin A were antagonized by both muscimol and diazepam (0.25 mg/kg, i.p., respectively), which are GABA(A) receptor agonists. Furthermore, oroxylin A (100 microM) was found to inhibit GABA-induced inward Cl(-) current in a single cortical neuron. These results suggest that oroxylin A may be useful for the treatment of cognitive impairments induced by cholinergic dysfunction via the GABAergic nervous system. 相似文献

A continuous stochastic logic with a μ-operator μCSL is defined, and an interpretation through stochastic relations is proposed. We investigate morphisms for models of μCSL, showing that the associated congruences can be used for an investigation of bisimilarity. The Hennessy–Milner equivalence for μCSL is discussed, and it is shown that models are equivalent iff they are bisimilar, using a general criterion for bisimilarity from the theory of stochastic relations. 相似文献

本文探讨了心理学研究工具的几个侧面:在心理学研究工具的界定问题上,心理学科同时具备自然科学和社会科学属性的学科特殊性,造成了心理学研究工具的多样化,应以一种更宽广的视角来界定心理学研究工具;在心理学研究工具的价值上,本文探讨了研究工具与心理学理论的相互影响和相互关系,理论假设会对工具使用过程造成影响,而工具的使用和发展对理论的建构和发展也有着重要的影响。在心理学研究工具的发展趋势上,在部分科研工具的高端化和精密化的同时,教学演示工具、学生实验仪器、心理测验、心理康复与心理治疗工具表现出不同的发展趋势。 相似文献

In the classical test theory, a high-reliability test always leads to a precise measurement. However, when it comes to the prediction of test scores, it is not necessarily so. Based on a Bayesian statistical approach, we predicted the distributions of test scores for a new subject, a new test, and a new subject taking a new test. Under some reasonable conditions, the predicted means, variances, and covariances of predicted scores were obtained and investigated. We found that high test reliability did not necessarily lead to small variances or covariances. For a new subject, higher test reliability led to larger predicted variances and covariances, because high test reliability enabled a more accurate prediction of test score variances. Regarding a new subject taking a new test, in this study, higher test reliability led to a large variance when the sample size was smaller than half the number of tests. The classical test theory is reanalyzed from the viewpoint of predictions and some suggestions are made. 相似文献

This paper considers the claim that C. G. Jung used a Lamarckian model of evolution to underwrite his theory of archetypes. This claim is challenged on the basis of Jung's familiarity with and use of the writings of James Mark Baldwin and Conway Lloyd Morgan, both of whom were noted and forceful opponents of neo-Lamarckian theory from within a neo-Darwinian framework. The paper then outlines the evolutionary model proposed by Baldwin and Lloyd Morgan, which has come to be known as Baldwinian evolution or the Baldwin effect. This model explicitly views psychological factors as central to the evolutionary process. Finally, the use of Baldwinian thinking in contemporary theorizing regarding language and other symbolic systems is reviewed and suggestions are made regarding the implications of Baldwinian models for theory building in analytical psychology. 相似文献

不同来源的财富因其在人们心理的权重差异会导致对其消费态度与方式的不同。前人运用一系列行为实验已发现意外所得更容易消费、辛苦所得则不容易消费。基于心理账户和内隐社会认知等理论, 运用IAT和ERP考察财富的意外所得与辛苦所得在人们心理引起的内在消费偏差, 进而对内隐消费态度和脑加工机制进行间接检测。IAT研究结果表明, 意外所得与容易消费的联结更加紧密, 辛苦所得与不易消费的联结更加紧密, 从内隐层面验证了前人的行为研究结论; ERP研究结果发现辛苦所得与意外所得这两个不同收入来源可能建立了不同脑加工机制, 且在P3和LPC成分得到反映, P3成分可能是反映辛苦所得组偏好难消费型消费方式的ERP成分, LPC反映了意外所得收入条件下个体偏好易消费型消费方式的特点。 相似文献
