儿童语言和认知(思维)发展的关系 总被引:9,自引:0,他引:9
在对幼儿从出生到3岁语言发展追踪研究和有关实验研究结果的基础上,比较、分析儿童语言和认知(思维)发展的各阶段及起作用的因素,探讨语言发展和认知发展的关系,提出以下几点看法:(1)儿童在1岁前(前语言期)的具体思维阶段有认知(有感知、记忆、表象和思维),但还没有真正的语言。这说明语言不是先于思维,也不是所有的思维都与语言相联系。但是,人类特有的抽象思维却与语言有着密切的联系。(2)认知(思维)发展是语言发展的基础。(3)认知(思维)发展和语言发展的关系是双向的,辩证的,是复杂地交互作用的。(4)应以辩证的唯物主义的观点来看语言和认知(思维)的产生。人类所以有语言,有高度抽象概括的思维,都源于人类的实践活动。 相似文献

The consequence argument attempts to show that incompatibilism is true by showing that if there is determinism, then we never had, have or will have any choice about anything. Much of the debate on the consequence argument has focused on the “beta” transfer principle, and its improvements. We shall show that on an appropriate definition of “never have had, have or will have any choice”, a version of the beta principle is a theorem given one plausible axiom for counterfactuals (weakening). Instead of being about transfer principles, the debate should be over whether the distant past and laws are up to us. 相似文献

Updating a previous systematic review of the literature, this review summarizes the literature over the last 5 years on the relationship between school-based extracurricular activity participation and academic achievement, substance use, sexual activity, psychological adjustment, and delinquency. The review also considers mediators and moderators of these relationships. This review also discusses recent advances in activity research including participation measurement (intensity, breadth, and duration), person-centered approaches, and an exploration of the overscheduling hypothesis. The review reveals a mixed picture of the relationship between activity participation and these adolescent developmental outcomes. A call for continued exploration into measurement issues, analysis approaches, outcome measures, and causal models of activities and adolescent functioning is made. 相似文献

A simple form of training the conscious control of motor units in skeletal muscle has been demonstrated in a series of children under age 6. Easy boredom is the chief deterrent in the very young. So long as a child understands and cooperates, he can learn to isolate single units in a period of about 30 min. 相似文献

The authors' primary purpose in the present experiment was to determine if practice changes the extent to which simple motor sequences are effector independent. Contralateral and ipsilateral effector transfers were assessed in 24 participants after 1 (200 trials) and 4 (800 trials) days of practice. The response sequence became increasingly effector dependent; the response structure and the scaling of force on the effector transfer tests were no better after 4 days of practice than after only 1 day, even though retention performance improved substantially. Those results are consistent with the notion that participants refine their movements over extended practice by exploiting the unique characteristics of the effectors. The additional practice results in a more effective movement when the same effectors are used but is of little value when different effectors are required. 相似文献

This study examined how toddlers gain insights from source video displays and use the insights to solve analogous problems. The sample of 2- and 2.5-year-olds viewed a source video illustrating a problem-solving strategy and then attempted to solve analogous problems. Older, but not younger, toddlers extracted the problem-solving strategy depicted in the video and spontaneously transferred the strategy to solve isomorphic problems. Transfer by analogy from the video was evident only when the video illustrated the complete problem goal structure, including the character’s intention and the action needed to achieve a goal. The same action isolated from the problem-solving context did not serve as an effective source analogue. These results illuminate the development of early representation and processes involved in analogical problem solving. Theoretical and educational implications are discussed. 相似文献

The purpose of this research was to test the hypothesis that the relative involvement of peripheral versus central nervous system activity during response variations determines the locus of error production in a subsequent criterion response. The hypothesis was tested by comparing ipsilateral and contralateral transfer of a criterion response following response variations that emphasized proportionately different involvement of the peripheral and central systems. When subjects were provided with knowledge of results (KR) to maintain a 30% maximum voluntary contraction (MVC), ipsilateral but not contralateral bias errors occurred on a subsequent dynamic response. When subjects maintained a 30% MVC without KR, however, subsequent ipsilateral bias errors were greater than contralateral bias errors. Finally, when subjects imaged a 30% MVC, subsequent bias errors were equivalent across limbs. These results are interpreted as support for the hypothesis. 相似文献

AbstractTranshumanists have asserted that religious people would both oppose life extension and allowing people with extended lives to die. In this paper, coming from a Roman Catholic perspective, I refute four myths associated with these claims: that the Church materially opposes life extension, that it conceptually opposes the very idea of life extension, that it opposes human genetic manipulation, and that it opposes letting people die in hospitals. I then propose that there are four real tensions that are much more significant: that material immortality is highly improbable, that injustice and inequality are major concerns, that transhuman omnipotence is impossible, and that utopianism is extremely dangerous. 相似文献

SUMMARY Engaging adults with Alzheimer's disease in activities can prevent disease related agitation. Finding meaningful and enjoyable activities proves to be a difficult task due to severe damage to explicit memory and executive functioning. Fortunately, many spiritual and religious activities rely on more resilient cognitive features such as procedural memory and limbic system aspects of attachment and motivation. Such spiritual activities, if properly selected, can be used to engage adults with dementia. This approach, called Procedural and Emotional Religious Activity Therapy, can be used by various religious traditions and extended to multiple therapeutic venues. 相似文献

The effects of musically‐induced positive and anxious mood on explicit alcohol‐related cognitions (alcohol expectancy strength) in 47 undergraduate students who consume alcohol either to enhance positive mood states (for enhancement motives) or to cope with anxiety (for anxiety‐related coping motives) were investigated. Pre‐ and post‐mood induction, participants completed the emotional reward and emotional relief subscales of the Alcohol Craving Questionnaire – Now. The hypothesis that anxiety‐related coping motivated drinkers in the anxious mood condition (but not those in the positive mood condition) would exhibit increases in strength of explicit emotional relief alcohol expectancies after the mood induction was supported. An additional, unanticipated finding was that enhancement‐motivated drinkers in the anxious condition also showed significant increases in strength of explicit emotional relief (but not emotional reward) alcohol expectancies. The hypothesis that enhancement‐motivated (but not anxiety‐related coping motivated) participants would exhibit increases in explicit emotional reward expectancies following exposure to the positive mood induction procedure was not supported. Taken together with past research findings, the current results highlight the importance of distinguishing between subtypes of negative affect (i.e., anxious and depressed affect) in exploring the affective antecedents of explicit alcohol outcome expectancies. 相似文献
