Objective indices (heart rate, perspiration quantity, finger plethysmograph curves, and facial expression) and subjective indices (sensory and emotional subject reports) were recorded for 25 young Chinese adults (16 men, 9 women) during and after the simultaneous application of a strong pain stimulus and either foot classical (alloneural points Tsusanli and Yanglingchuan) or hand classical (alloneural points Hegu and Neiguan) acupuncture. Both forms of acupuncture were equally effective, showing that stimulation of the same nerve is not essential for pain relief. Acupuncture assuaged the emotional, but not the sensory, response to the painful stimulation.  相似文献

We compare over a two-octave range the tonal, interval, and scale relationships of an ancient Chinese bell ensemble of the Zhou Dynasty and a modern bamboo flute. By using subjective pitches, a tonal system with simple harmonic partials (the flute) could be compared with a tonal system with complex inharmonic partials (the bell). We argue that the underlying musical scales of the bell ensemble and the flute are closely related and lie between an unequal-interval pure-system scale and the just-intonation scale. There is some evidence that a least interval of 60 or 66 cents figures in the flute scale, that both flute and bell scales include a 90-cent interval and a true (1,200-cent) octave, and that neither scale includes a 100-cent interval. Since there is a true octave, the scales cannot be cycles of fifths, and since there is no equal-temperament half-tone (100 cents), the scales cannot be equal in temperament. We conclude that the flute and Zhou bell scales are very similar if not the same. Apparently, strong cultural traditions and human perceptual constancies united to sustain a common flexible musical scale during 2,400 years.  相似文献

This essay is intended to be a systematic exposition and critique of Daniel Dennett's general views. It is divided into three main sections. In section 1 we raise the question of the nature of a plausible scientific psychology, and suggest that the question of whether folk psychology will serve as an adequate scientific psychology is of special relevance in a discussion of Dennett. We then characterize folk psychology briefly. We suggest that Dennett's views have undergone at least one major change, and proceed to discuss both his earlier and his later views.In section 2 we suggest that Dennett is correctly perceived as an instrumentalist in his earlier works. We think that Dennett later abandons this position because of general worries about instrumentalism and, more importantly, because Dennett became convinced that an instrumentalist conception of folk psychology will not enable us to vindicate the notions of personhood, moral agency, and responsibility. This left Dennett with a dilemma. On the one hand, he does not think that beliefs, etc., will turn out to be genuine scientific posits. On the other hand, he thinks that moral agency would be impossible if we could not treat beliefs, etc. as causally efficacious in some suitable sense.In section 3 we discuss Dennett's resolution of this dilemma. The key to his current view, we suggest, is the illata-abstracta distinction. Dennett holds that both illata and abstracta are real and have causal powers, even though only illata are genuine scientific posits. He suggests that beliefs etc. are abstracta, and are the subject matter of what he calls intentional system theory. The subject matter of another theory, what Dennett calls subpersonal cognitive psychology, are illata, which are subpersonal intentional states. The important point is that this distinction lets Dennett have it both ways: (i) Since beliefs are mere abstracta, we need not commit ourselves to the thesis that beliefs will turn out to be posits of an adequate scientific psychology. (ii) Since beliefs have causal power, we are assured of moral and rational agency. We shall argue that Dennett's current view is untenable. If we are right in our arguments, then Dennett's program to produce a scientifically plausible psychology, one that will turn out to vindicate folk psychology (in some suitable sense), is a failure. It fails in the following important ways: (i) What Dennett sketches — intentional system theory cum subpersonal cognitive psychology — is not a plausible scientific psychology. (ii) As a consequence, Dennett also fails to provide a satisfactory foundation for moral and rational agency.  相似文献

汉语语词码相加效应的实验研究   总被引:1,自引:0,他引:1  
喻柏林 《心理学报》1986,19(1):52-59
本实验在汉语双音合成词基础上,通过词与词之间在形码、音码和义码方面的关系,实现了一个以上的码的相加,从而证实汉语语词能为语词记忆的研究提供新的途径和适合需要的语词材料。 本实验结果发现,码的相加效应主要不反映在语词记忆的获得过程上,因为多个码与单一码的汉语语词材料都具有大致相等的获得水平,但在短时记忆的自发恢复和信息从短时记忆向长时记忆转换等现象上,已开始显露码的相加效应。在信息的长时保持和提取中,码的相加效应得到明显而有力的表现。而且,随着编码维量数的增加,其相加效应的优势也随之增加.因此可以认为,码的相加效应主要影响信息的长时保持和提取,而对信息的获得影响不大。此外,作为自变量的、被编码的词的维量数似乎与自由回忆下的系列位置曲线无关。  相似文献

本文是以大白鼠在三等分迷宫仪中学习防御性条件反应的方法,观察800拉特γ-线对大白鼠学习能力的影响。实验结果表明,大白鼠的学习能力是下降的,其表现为每天学习的正确率低,达到学会标准所需学习次数增加;反应运动时延长;主动躲避反应的出现率降低。 根据受照动物的特点,我们认为:作为判断学习和记忆能力的指标,反应运动时比正确率更好一点。  相似文献

本工作研究两例先天性无痛症患者的心理特点,主要是其情绪特点,以探讨疼痛和情绪的关系,并借以检验疼痛学说的意义。例一,女,10岁,智力略低于正常,艾森克少年儿童人格问卷表评定人格正常。与身体损伤有关的恐惧感明显缺乏,但与社会和教育影响有联系的恐惧感却甚于正常儿童。情绪急躁,易发作暴发性脾气而不能控制。在突然刺激(强光、强铃声)下的反应和正常儿童相近。例二,男,13岁,智力明显落后,人格评定正常,各种恐惧感均明显缺乏。情绪经常呈明显欣快状态。突然刺激下有口语惊吓和动作反应但无相应的面部表情和植物性神经系统的变化。两例均有无目的的多动作表现。看来疼痛和情绪有某种关系,但本结果并不能证实疼痛的情绪学说。  相似文献

How do early bilingual experiences influence children's neural architecture for word processing? Dual language acquisition can yield common influences that may be shared across different bilingual groups, as well as language-specific influences stemming from a given language pairing. To investigate these effects, we examined bilingual English speakers of Chinese or Spanish, and English monolinguals, all raised in the US (= 152, ages 5–10). Children completed an English morphological word processing task during fNIRS neuroimaging. The findings revealed both language-specific and shared bilingual effects. The language-specific effects were that Chinese and Spanish bilinguals showed principled differences in their neural organization for English lexical morphology. The common bilingual effects shared by the two groups were that in both bilingual groups, increased home language proficiency was associated with stronger left superior temporal gyrus (STG) activation when processing the English word structures that are most dissimilar from the home language. The findings inform theories of language and brain development during the key periods of neural reorganization for learning to read by illuminating experience-based plasticity in linguistically diverse learners.  相似文献

People who consider themselves moral sometimes use self-serving justifications to rationalize their selfish behaviours. Previous studies have tested the role of ambiguity in justifying wrongdoings, but it remains unclear whether ambiguity also plays a role in justifying promise-breaking behaviour and whether heterogeneity exists. To investigate justification in promise-breaking, we introduced a new experimental paradigm called the card-guessing task and used hierarchical cluster analysis to classify participants based on their promise-breaking decisions in unambiguous and ambiguous conditions. Experiment 1 revealed three clusters of solutions: Cluster 1 always kept their promises (i.e., keepers); Cluster 2 only exploited the vague promises and broke their promises in the ambiguous condition (i.e., intermediates); Cluster 3 tended to take advantage of vague promises and broke their promises irrespective of ambiguity (i.e., breakers). Experiment 2 confirmed that participants in the three clusters differed in their norm-abiding preferences and social value orientations. Keepers were more altruistic and had a stronger sense of norm compliance than intermediates and breakers. In conclusion, our study demonstrates that self-serving justifications were more likely to be employed by people who are moderately sensitive to deviation from social norms, which has implications for strategic interventions and policy formulation concerning unethical behaviour.  相似文献
