Group members are challenged to form psychologically meaningful relationships with therapists, other members, and the group
as a whole. The way in which individuals perceive this challenge is based on their past experiences. Early relationships establish
a perceptual frame in which fears of being hurt and concern about hurting others coexist. Balance between these two ways of
generating meaning enables individuals to form relatively healthy relationships. Imbalance in this perceptual frame results
in distorted perceptions and maladaptive patterns emerging as transference manifestations. Working through involves repeatedly
addressing distortions as members relate to therapists, others and the group as a whole. 相似文献

客体与空间工作记忆的分离:来自皮层慢电位的证据 总被引:2,自引:0,他引:2
利用128导事件相关电位技术,采用延迟匹配任务的实验范式,测查了16名正常被试在完成客体任务和空间任务时的皮层慢电位(slow cortical potentials,简称sp成分),实验发现:在后部脑区,客体工作记忆与空间工作记忆在慢波活动的时间上存在分离,空间任务更早的诱发出负sp成分,并且空间任务激活更多的后部脑区;左下前额叶在客体工作记忆任务与空间工作记忆任务中都有激活,并且激活强度不存在显著差异;背侧前额叶主要负责客体信息的保持与复述,但左右背侧前额叶的激活强度存在不对称性。 相似文献

在言语-表象认知风格模型中, 视觉表象认知风格一直被视为单一的结构, 且在此基础上发展出的各种测量方法均存在效度上的缺陷, 导致了研究者对该认知风格模型的普遍质疑。随着对视觉认知加工研究的深入, 尤其是对视觉客体表象与视觉空间表象在功能和解剖上的双分离的理解, 为进一步区分表象型认知风格提供了理论和实证依据, 进而促进了客体-空间表象和言语(Object-Spatial Imagery and Verbal, OSIV)认知风格模型的提出, 而在此基础上开发的新测量工具(Object-Spatial Imagery and Verbal Questionnaire, OSIVQ)具有良好的信、效度, 有力地支持了OSIV认知风格模型。OSIV认知风格模型及其测量为研究人类的认知风格以及视觉认知拓展了新视野。尽管如此, 两种不同视觉表象子系统并存于个体的视觉表象系统中, 因此, 它们分离的原因、相互作用及其与视觉注意之间的关系有待进一步研究。 相似文献

Acquisition of arbitrary conditional discriminations by young normally developing children 下载免费PDF全文
Three experiments investigated conditions designed to facilitate acquisition of arbitrary conditional discriminations in 3- to 6-year-old normally developing children. In Experiment 1, 6 subjects failed to master the arbitrary match-to-sample task under conditions of differential reinforcement alone, but 7 subjects did so when instructions or instructions and sample naming were added. In Experiment 2, sample naming introduced in a blocked-trial arrangement resulted in acquisition, but only when the sample name was a nonsense syllable provided by the experimenter (5 of 7 subjects) and not when the sample name was generated by the subject (0 of 5 subjects). Experiment 3 demonstrated the effectiveness of a training sequence involving thematically related stimuli as an intermediate step facilitating the transition from identity to novel arbitrary relations. The difficulties in mastering arbitrary conditional discriminations shown here imply that further analyses with young children will be particularly important in efforts to investigate the development of theoretically important stimulus relations. 相似文献

If the question “What is a gene?” proves to be worth asking it must be able to elicit an answer which both recognizes and address the reasons why the concept of the gene ever seemed to be something worth getting excited about in the first place as well analyzing and evaluating the latest develops in the molecular biology of DNA. Each of the preceding papers fails to do one of these and sufferrs the consequences. Where Rolston responds to the apparent failure of molecular biology to make good on the desideratum of the classical gene by veering off into fanciful talk about “cybernetic genes,” Griffiths and Stotz lose themselves in the molecular fine print and forget to ask themselves why “genes” should be of any special interst anyway. 相似文献

We define an automata-theoretic counterpart of (type-logical)grammars based on the (associative) Lambek-calculus L, a prominentformalism in computational linguistics. While the usual push-downautomaton (PDA) has the same weak generative power as the L-basedgrammars (Pentus, 1995), there is no direct relationship betweenthe computations of a PDA for some language L and the derivationsof an L-based grammar for L. In the Lambek-automaton, on theother hand, there is a tight relation (1-1) between automatoncomputations and grammar derivations. The automaton exhibitsa novel mode of operation, using hypothetical steps, directlyinspired by the hypothetical reasoning embodied by L. 相似文献

In this paper, the authors discuss Frege's theory of logical objects (extensions, numbers, truth-values) and the recent attempts to rehabilitate it. We show that the eta relation George Boolos deployed on Frege's behalf is similar, if not identical, to the encoding mode of predication that underlies the theory of abstract objects. Whereas Boolos accepted unrestricted Comprehension for Properties and used the eta relation to assert the existence of logical objects under certain highly restricted conditions, the theory of abstract objects uses unrestricted Comprehension for Logical Objects and banishes encoding (eta) formulas from Comprehension for Properties. The relative mathematical and philosophical strengths of the two theories are discussed. Along the way, new results in the theory of abstract objects are described, involving: (a) the theory of extensions, (b) the theory of directions and shapes, and (c) the theory of truth values. 相似文献

This study focuses on the development of spontaneous object manipulation in three infant chimpanzees during their first 2 years of life. The three infants were raised by their biological mothers who lived among a group of chimpanzees. A human tester conducted a series of cognitive tests in a triadic situation where mothers collaborated with the researcher during the testing of the infants. Four tasks were presented, taken from normative studies of cognitive development of Japanese infants: inserting objects into corresponding holes in a box, seriating nesting cups, inserting variously shaped objects into corresponding holes in a template, and stacking up wooden blocks. The mothers had already acquired skills to perform these manipulation tasks. The infants were free to observe the mothers' manipulative behavior from immediately after birth. We focused on object–object combinations that were made spontaneously by the infant chimpanzees, without providing food reinforcement for any specific behavior that the infants performed. The three main findings can be summarized as follows. First, there was precocious appearance of object–object combination in infant chimpanzees: the age of onset (8–11 months) was comparable to that in humans (around 10 months old).Second, object–object combinations in chimpanzees remained at a low frequency between 11 and 16 months, then increased dramatically at the age of approximately 1.5 years. At the same time, the accuracy of these object–object combinations also increased. Third, chimpanzee infants showed inserting behavior frequently and from an early age but they did not exhibit stacking behavior during their first 2 years of life, in clear contrast to human data. 相似文献

听力正常人与聋人短时记忆的比较研究 总被引:7,自引:1,他引:6
以视觉系列呈现,自由回忆的方法比较了听力正常人与聋人对分别被强化的厂类相似性汉语字表的短时记忆获得量。从总的平均获得量来看,两组结果没有显著差异,而从每一编码维量在短时记忆的加工过程中的作用来看,两组被试都显示出了形、义两维编码维量的作用最强,而音码的作用相对比较弱。两组被试也都显示出了明显的系列位置效应,但聋人组的次级记忆容量明显地低于听力正常组,而初级记忆容量两组没有显著差异。并对可能的机制进行了讨论。 相似文献
