Based upon predictions of equilibrium-point (EP) models of motor control, a recent article by Jaric et al. (1999) [Human Movement Sciences, 18, 49–66] reported that the peak velocity (PV) of an inertially loaded single degree-of-freedom elbow movement was not altered to a statistically distinguishable degree by the accuracy of the subject's expectation about the size of the load. They concluded that their results confirmed their EP models and were incompatible with what they described as torque-control models. A review of the literature and analysis of a more extensive set of data does not support that conclusion. To the contrary, if the actual load is heavier (or lighter) than expected, it is moved more slowly (or faster) than it would have been, had expectation matched reality. Torque-control models predict those consequences, EP models do not. 相似文献

FOK:是线索熟悉,还是目标提取? 总被引:7,自引:0,他引:7
以围棋定式为实验材料,检验了关于FOK判断的线索熟悉假说和目标提取假说。结果表明:在有线索可以利用的情况下,被试会依据线索的熟悉作出FOK判断;而在线索难以利用的情况下,被试就会依据目标的提取来作出FOK判断。该文还对FOK的研究方法提出了一点看法。 相似文献

English uses the horizontal spatial metaphors to express time (e.g., the good days ahead of us). Chinese also uses the vertical metaphors (e.g., 'the month above' to mean last month). Do Chinese speakers, then, think about time in a different way than English speakers? Boroditsky [Boroditsky, L. (2001). Does language shape thought? Mandarin and English speakers' conceptions of time. Cognitive Psychology, 43(1), 1-22] claimed that they do, and went on to conclude that 'language is a powerful tool in shaping habitual thought about abstract domains' (such as time). By estimating the frequency of usage, we found that Chinese speakers actually use the horizontal spatial metaphors more often than the vertical metaphors. This offered no logical ground for Boroditsky's claim. We were also unable to replicate her experiments in four different attempts. We conclude that Chinese speakers do not think about time in a different way than English speakers just because Chinese also uses the vertical spatial metaphors to express time. 相似文献

In Robbins, R. & McKone, E. (2006). No face-like processing for object-of-expertise in three behavioural tasks. Cognition this issue, we showed face-like holistic/configural processing does not occur for objects-of-expertise on standard paradigms including inversion, part-whole, part-in-configurally-transformed-whole, and the standard composite task. In this reply to the discussion by Gauthier, I., & Bukach, C. (2006). Should we reject the expertise hypothesis? Cognition, this issue, we focus on several issues: the fact that they do not dispute our review of previous data; the strength of null effects obtained from multiple studies and paradigms; the evidence for domain-specificity of the neural substrate supporting face processing; the difference between the expertise hypothesis (as a theory about the origin of face processing) and studies of how experience affects object processing in general; and the problems with G&B's proposed alteration to the standard composite paradigm. We argue that overwhelming evidence suggests the expertise hypothesis should be put to rest so that researchers can focus on what the origin of "special" processing for faces actually is, and investigate the many interesting changes to object recognition that do occur with experience. 相似文献

Production studies have shown that speakers of languages with larger phoneme inventories expand their acoustic space relative to languages with smaller inventories [Bradlow, A. (1995). A comparative acoustic study of English and Spanish vowels. Journal of the Acoustical Society of America, 97(3), 1916-1924; Jongman, A., Fourakis, M., & Sereno, J. (1989). The acoustic vowel space of Modern Greek and German. Language Speech, 32, 221-248]. In this study, we investigated whether this acoustic expansion in production has a perceptual correlate, that is, whether the perceived distance between pairs of sounds separated by equal acoustic distances varies as a function of inventory size or organization. We used magnetoencephalography, specifically the mismatch field response (MMF), and compared two language groups, French and Spanish, whose vowel inventories differ in size and organization. Our results show that the MMF is sensitive to inventory size but not organization, suggesting that speakers of languages with larger inventories perceive the same sounds as less similar than speakers with smaller inventories. 相似文献

Author experiment using a modified version of the Buss' aggression paradigm tested Berkowitz' completion hypothesis, which states unsuccessful aggressive attempts at the frustrator serve as further frustration and intensify aggression. Testing was done by varying the number of successful aggressive attempts for different experimental groups. The experiment indicated first a positive relationship between subjective levels of frustration and aggression, which supports a general frustration-aggression hypothesis, and second that unsuccessful aggressive attempts lead to increased aggression in terms of shock intensity. This was interpreted as supportive of Berkowitz' completion hypothesis, although alternative interpretations in terms of cognitive and behavioral strategies cannot be excluded. 相似文献

催产素被誉为“爱的荷尔蒙”, 与依恋有着密切关系。以往研究已证明不同来源的催产素对不安全依恋者的人际适应性会产生不同的影响, 主要表现为内源性催产素水平越低, 不安全依恋者的人际适应性越差; 外源性催产素增强了依恋回避个体的人际适应性, 但降低了高依恋焦虑个体的人际适应性; A、G等位基因与不安全依恋者的人际适应性有关。此外还借助依恋理论和社会显著假说解释了上述影响, 不安全依恋者的防御性排斥、环境因素和个体差异调节了催产素的效应。未来应比较催产素受体基因与不安全依恋者人际适应性关系的差异, 催产素影响不安全依恋者人际适应性的性别差异问题, 并在人际互动过程中研究催产素对不安全依恋者人际适应性的影响, 以增强催产素研究的生态效度。 相似文献

We tested the hypothesis that people show generality in their endorsement of unsubstantiated claims, employing more types of measures than used in previous studies. We found that measures of generic conspiracist ideation, specific fictitious conspiracy theory, and false conspiracy theory beliefs were all strongly and positively intercorrelated. A multiple regression analysis revealed that the measures of specific false and fictitious conspiracy theories both significantly predicted generic conspiracist ideation. A second broader test of the generality hypothesis showed that these measures of false and fictitious conspiracy belief were positively intercorrelated with measures of psychological misconceptions, pseudoscience, poorly supported psychological practices, and paranormal beliefs. However, the measures of misconceptions and pseudoscience displayed substantially lower correlations. The results provide support for the generality of acceptance of a wider variety of unsubstantiated claims than used in previous studies and also suggest differences in the types endorsed based on the kind of knowledge and content measured. 相似文献

该研究探讨了语言范畴对注意前颜色知觉的影响依赖于语言范畴与颜色长期联结还是其即时分类颜色,同时检验了习得的语言范畴是否能因果性地改变早期颜色知觉机能。采用G1、G2、B1、B2(前两者为绿色,后两者为蓝色)4种连续变化的颜色为材料。学习组和分类组被试分别接受6次和1次色词与颜色重组训练,学习4种颜色不同的新名称,并在之后均接受视觉Oddball脑电测试。训练结果显示:学习组稳定地习得了4种颜色的新名称,分类组能以新名称将颜色分为4类。测试结果显示:学习组的颜色知觉中出现了与习得语言范畴对应的偏侧化注意前颜色范畴知觉,分类组的颜色知觉中未出现与颜色分类对应的偏侧化注意前颜色范畴知觉。研究结果表明:语言范畴对注意前颜色知觉的影响依赖于语言范畴与颜色长期联结而非其即时分类颜色;习得的语言范畴能引起偏侧化注意前颜色范畴知觉,提示习得的语言范畴能因果性地改变早期颜色知觉机能。 相似文献
