动机连续体是对内部动机、外部动机进行整合的心理学概念,其对内部动机和外部动机的争论提出了不同的假设。从大理论(grand theory)视角出发,对涉及上述两个概念的理论进行梳理,将自我决定理论与其他相关理论进行整合。由此展开对内部动机、外部动机结构的讨论,总结了动机的单维结构、多维结构和复杂结构假设下的理论新进展,分别论述在拮抗效应、累加效应和其他复杂效应等假设下动机对结果变量的影响,并展开不同效应对实践应用的讨论。 相似文献

Electromagnetic articulography: use of alternating magnetic fields for tracking movements of multiple points inside and outside the vocal tract 总被引:3,自引:0,他引:3
The purpose of this paper is to present a new electromagnetic device which uses alternating magnetic fields for tracking movements of multiple points inside and outside the vocal tract. It is biologically safe, noninvasive, it does not interfere with speech movements, allows for multiple recording in the same subject, and for easy collection of large amounts of data. It is especially suitable for evaluation of patients with speech motor impairments. 相似文献

Anxiety, nausea and vomiting before, during and after chemotherapy administration were studied in 50 cancer patients. In addition, patient responses to the Autonomic Perception Questionnaire (APQ) and their relation to the anxiety, nausea and vomiting scores was studied. Anticipatory anxiety occurred in 66% and anticipatory nausea in 40% of the patients; 14% showed anticipatory vomiting. The number of patients reporting anxiety decreased to 38% after chemotherapy, whereas nausea and vomiting increased to 47 and 49%, respectively. APQ scores correlated significantly with anxiety and nausea reports during all time periods, but not with the frequency of vomiting. 相似文献

Sleep in the dove Zenaida asiatica 总被引:1,自引:0,他引:1
Electrographic and behavioral observations were made in five adult birds of the genus Zenaida asiatica. Five different vigilance states were quantitated: (1) Active waking (Aw) was characterized by constant behavioral activity; the nuchal electromyogram was tonically active with bursts associated to movements. The electroencephalographic pattern was low voltage and high frequency. (2) Quiet waking (Qw) was characterized by diminished behavioral activity and the EEG pattern was similar to that of Aw. (3) Drowsiness (D) was characterized by behavioral calm. Frequency of cerebral activity diminished progressively, but there were short periods of desynchronization corresponding to brief awakenings. (4) Slow wave sleep (SWS); during this period there was behavioral rest and EEG pattern of continuous slow waves and the nuchal EMG was tonically reduced. Spindles of sleep were not observed. (5) Paradoxical sleep (SP), behaviorally characterized by phasic manifestations consisting of noddings originated by rapid falling down of head and bursts of rapid eye movements. EEG activity was like that of waking state. EMG activity was maintained at the same level as during SWS but sometimes it decreased lightly. Total atonie was not observed. Sleep percentages were higher when recordings were done during the nocturnal period. 相似文献

Relational frame theory,acceptance and commitment therapy,and a functional analytic definition of mindfulness 总被引:1,自引:0,他引:1
Lindsay?Fletcher Steven?C.?HayesEmail author 《Journal of Rational-Emotive & Cognitive-Behavior Therapy》2005,23(4):315-336
The present article interprets mindfulness from the point of view of the effects of language and cognition on human action. Relational Frame Theory is described to show how human suffering is created by entanglement with the cognitive networks made possible by language. Mindfulness can be understood as a collection of related processes that function to undermine the dominance of verbal networks, especially involving temporal and evaluative relations. These processes include acceptance, defusion, contact with the present moment, and the transcendent sense of self. Each of these components of mindfulness are targeted in Acceptance and Commitment Therapy, and there is some evidence that they underlie the therapeutic changes induced by this approach. The relation between the present approach to mindfulness and other approaches is discussed. 相似文献

具身认知理论是目前认知科学领域中最新的研究范式和取向, 它认为人的认知过程依赖于感知和动作系统, 强调身体在认知中发挥重要作用。具身语言理解则认为, 身体、动作和知觉系统在语言认知中也起着不可或缺的作用。文章在简要回顾具身语言理解的相关理论如索引假设、浸入式经历者框架、语言神经理论的基础上, 重点从语言理解的四个层面的实证研究, 即音位、单词、句子、语篇, 证实具身语言理解的观点。未来的研究应该着眼于用具身认知观点来解释更高级的抽象语言表征, 具身单词、句子、语篇的具体表征形式, 并利用具身语言认知的观点进行认知的本土化研究。 相似文献

The present study examined the role played by protective factors in moderating the effects of risk factors over bullying and victimization in a sample of 679 male adolescents recruited in Italian high schools. Boys’ involvement in bullying revealed that one in three students has bullied others at least sometimes in the previous three months, and one in six has been victimized at the same rate; victimization decreases with age. The family related risk factor (conflicting parents) was positively associated with bullying and with victimization (together with punitive parenting); the same applied for risk factor related to the individual ways of dealing with problems (emotionally oriented coping skills). Protective factors related to the family context (supportive and authoritative parents) and to the individual (problem solving coping skills) were negatively associated to bullying and victimization. Hierarchical regression analyses revealed a moderating effect of supportive parenting on punitive parenting and on emotionally oriented coping strategies in predicting victimization. Problem solving coping strategies helped buffer the negative impact of emotionally oriented coping strategies over bullying. Implications of results for practitioners and for future studies are addressed. 相似文献
