Determinants of phrasing effects in rat serial pattern learning   总被引:1,自引:0,他引:1  
Two experiments investigated how brief pauses introduced into serial patterns as phrasing cues would affect pattern learning in rats. In Experiment 1, a 24-element pattern consisted of eight 3-element chunks, whereas a 20-element pattern consisted of four 5-element chunks. In both patterns, 3.0-s temporal pauses placed at chunk boundaries (synchronous phrasing cues) facilitated learning compared to no phrasing. Cues "out of sync" with pattern structure (asynchronous phrasing cues) facilitated learning for the 24-element pattern and retarded learning for the 20-element pattern. Evidence suggested that in the latter case, 3.0-s pauses served as "blank" trials that induced rats to "skip" to the next serial position in sequence. In Experiment 2, shorter 0.5-s pauses served as phrasing cues in the 20-element pattern of Experiment 1. Synchronous short cues facilitated learning, whereas asynchronous phrasing cues had no effect. Furthermore, removal of synchronous cues produced deficits in performance on formerly cued trials, whereas removal of asynchronous cues had no effect. The results of Experiment 2 support the notion that in both experiments phrasing cues served as discriminative cues and indirectly suggest that rats are concurrently sensitive to pattern element cues, extra-sequence cues (such as phrasing cues), and to the relative timing of sequential events.  相似文献

3个实验探讨了儿童在归纳推理中是否具有多样性效应的争议。实验1采用寻找证据法,使用图片材料,得出5岁儿童在归纳推理中没有多样性效应,表现为典型性效应。实验2改用归属法发现:5岁儿童在归纳推理中表现出多样性效应。实验3采用寻找证据法,但使用实物材料,并且加大了多样性前提的差异程度,结果发现:3岁儿童在归纳推理中也表现出多样性效应。本研究结果表明,在适合的条件下,儿童在归纳推理中能表现出多样性效应。  相似文献

采用追踪设计对459名儿童的父母进行问卷调查,旨在考察父母元情绪、情绪反应与儿童社会适应的复杂作用关系。研究结果表明:(1)在控制了前测儿童敏感合作后,父亲的问题关注反应在父亲的情绪教导和儿童的敏感合作之间起中介作用;(2)在控制了前测儿童社会适应后,母亲的鼓励表达在母亲的情绪教导和儿童的违纪攻击、害羞焦虑之间起中介作用,母亲的问题关注反应在母亲的情绪教导和儿童的敏感合作之间起中介作用,母亲的苦恼反应在母亲的情绪教导、情绪摒除和儿童的敏感合作、害羞焦虑之间起中介作用。  相似文献

This paper uses aggregate data for a panel of 23 Sub-Saharan African countries to explore the potential predictors of road traffic fatalities between 2001 and 2010. In addition to the Gross Domestic Product per capita, the set of covariates includes some demographic, safe driving behavior, health and infrastructure-related variables. Estimations from a mixed effects negative binomial regression suggest that the fraction of populations aged between 15 and 64 years, the size of the road network and seat belt laws significantly increase fatalities. However, populations of age 65 and above, hospital beds and physicians’ densities, and road audits significantly decrease these fatalities. Moreover, traffic fatalities are found to increase with the Gross Domestic Product per capita. The economic implications of this finding is not to lower the economic growth but to design policies and technologies that could prevent African countries from experiencing the same road tragedy observed in industrialized countries during their development process.  相似文献

关联效应中对情绪诱词的错误再认的实验研究   总被引:1,自引:1,他引:0  
采用DRM范式,考察了在汉字单字词语音关联和形声关联条件下对具有情绪色彩的关键诱词的错误再认情况,结果表明:(1)汉字中存在着语音和字形关联,但是语音关联下的对诱词的错误再认率很低。(2)语音关联、形声关联条件下,尽管学习阶段没有出现带有情绪色彩的词,被试仍然对情绪诱词都产生了显著的错误再认。(3)形声关联下对关键诱词的错误再认近于语音关联的两倍,可见概括性的强度影响错误记忆的大小。  相似文献

Baby media have exploded in the past decade, and children younger than 2 are showing increased use of these baby media. This paper examines the historical evidence of babies’ use of television since the 1950s as well as the various factors that have given rise to the current increase in screen media for babies. We also consider the ubiquitous role of television in American families, the impact of evidence regarding the educational benefits of educational television on preschoolers, and positive parental beliefs about the usefulness of such educational media in preparing young children for schooling. Finally, we examine the theoretical issues of importance for guiding research into the interactions between media exposure and cognitive development, including the role of media in changing the context of children’s development and constraints on the kinds of things babies can learn from screen media. Lastly, we suggest that screen media may indeed be changing the nature of children’s development.  相似文献

同步放化疗的疗效明显优于单一放化疗和序贯放化疗,但毒副作用的叠加效应可引起严重的并发症,甚至造成死亡。本文从同步放化疗的作用机制和临床实践出发,通过对疗效与毒副作用之间的辩证关系进行具体分析,探讨了如何制定合理的肿瘤治疗决策。  相似文献

该文通过两个实验考察早期双语儿童第二语言的词汇概念组织。实验1运用跨语言重复启动的范式,结果发现了跨语言重复启动效应,说明早期双语儿童可以直接通达概念意义,但是二语词汇语义通达的强度要弱于一语词汇语义通达的强度。在实验1的基础上,实验2运用图片命名的范式,结果发现了命名的语言效应,进一步说明早期双语儿童二语词汇与概念表征的联系要弱于一语词汇与概念表征的联系。总的实验结果表明,早期双语儿童在记忆表征中建立了二语词汇与概念表征的直接联系,其第二语言的词汇概念组织在本质上是机能性的。  相似文献

This paper deals with the history of psychoanalysis (Freud) and analytical psychology (Jung) in the light of recent developments and considers the release of new creativity in the field after its deconstruction. Cross-cultural contributions in the form of teaching stories are estimated to be of relevance, while the emphasis will be on what we, as analysts, can learn from these teachings, rather than interpreting them in the more traditional way in which such stories can be shown to fit analytical theory.
The most crucial debate in psychoanalysis of the recent era centres around stories and the deconstruction thereof. It is the debate between Lacan and Derrida on the interpretation of a crucial story (Poe's story, The Purloined Letter). The core of their views will be discussed in this paper in the light of the major differences between Freud and Jung. Whereas Freud's theoretical core-complex is closely related to Lacan's phallocentric Truth, it is Derrida who speaks of germination and dissemination as the way in which Truth manifests itself. Derrida's thought on text and words is very close to Jung's conceptions of the image and symbol, in which there is no monotheistic paradigm ruling theory  相似文献
