Three experiments examined the role of three distinctive perceptual factors in recognition and recall memory. Using a subject-paced presentation rate, the first two experiments (recognition and recall) examined (1) the number of phonological-to-orthographic neighbors, (2) phonological-to-orthographic consistency, and (3) orthographic-to-phonological consistency. The third experiment (recall) reexamined the number of phonological-to-orthographic neighbors, using an experimenter-paced presentation rate of 2 sec per item. In both recognition and recall memory tasks, the number of phonological-to-orthographic neighbors influenced memory performance, whereas the two types of consistency did not. The results indicate that having fewer phonological-to-orthographic neighbors (i.e., having distinct mappings between orthography and phonology, and between phonology and orthography, e.g., pulp) relieve words from interference in episodic memory tests for such words. Furthermore, words that are indistinct in terms of these mappings (e.g., tuck) are subject to interference from words with similar representations (e.g., luck, buck, stuck), and this weakens the memory trace for a particular word.  相似文献

采用ERP方法,考察了汉语词汇歧义消解中句子语境作用的时间进程及大脑活动。目标词与句子语境存在一致、不一致、无关控制等3种关系。结果显示:(1)一致与不一致条件下N400的平均波幅均显著低于无关控制条件;(2)SOA为200毫秒时产生的N400平均波幅的幅度显著高于SOA为1000毫秒的条件;(3)N400的平均波幅及潜伏期均表现出左半球显著高于右半球的特点。实验结果支持词汇歧义消解的模块化观点,体现了大脑两半球语言功能的不对称性。  相似文献

癫痫治疗目前仍以长期科学规范的药物治疗为主,为保证医生的治疗计划得到贯彻,在诊治中努力寻求医患同盟的建立尤为重要,让患者清楚地认识到医生对他的关注,认识到医生治疗的计划性、和具有应对各种情况的措施方法和能力,是寻求患方合作的基本条件。本文就医生首诊中的任务、人文关怀的重要性、如何共同进行药物选择、副反应规避、家属不良治疗心态纠正等问题进行探讨。  相似文献

We report the results of four experiments in which we explored the flexibility and fallibility of associative recognition memory. In each experiment, pairs were studied one or more times, and the task was to discriminate intact from rearranged pairs. The critical findings are that the pattern of false alarm rates was dependent on the nature of the recognition procedure (e.g., ratings vs. yes-no) and the situation in which the task was performed. The specific pattern of findings suggest that subjects adopt different recognition strategies in order to achieve a desired level of performance in the most efficient manner possible by varying the degree to which they base their decisions on familiarity versus recollected information. Implications for theories of recognition memory are discussed.  相似文献

What response times tell of children's behavior on the balance scale task   总被引:4,自引:0,他引:4  
Analysis of accuracy of responses to balance scale problems gives a global idea of the cognitive processes that underlie problem-solving behavior on this task. We show that response times (RTs) provide additional detailed information about the kind and duration of these processes. We derive predictions about the RTs from Siegler's (1981) model for the balance scale task, including the counterintuitive prediction that young adults are slower than children in solving particular balance scale problems. The predictions were tested in a study in which 191 6- to 22-year-old participants were presented with a computerized balance scale task. RTs were analyzed with regression models. In addition to qualitative differences between items, we also modeled quantitative differences between items in the regression models. Analyses supported the predictions and provided additional knowledge on the rules. Rule II was reformulated as a rule that always involves the encoding, but not always the correct application of the distance cue. RTs provided evidence for the use of a buggy-rule and not an addition-rule. Finally, a relation between rule inconsistency and increased RT was found.  相似文献

Although the notion of a down low life style, called various things at various times, has a long history in the black community, the past few years have been marked by an exponential increase in attention of this phenomenon in both the mainstream press and scholarly work. However, much of this work has focused on exploring whether men on the down low present a unique threat for HIV infection to black women. Currently, there exist very few scholarly works exploring the lives of black men who have sex with men and women that specifically address their own experiences living on the down low or how these men personally define what it means to be on the down low. In this article, we explore why black men who have sex with men and black men who have sex with men and women, including those who self-identify as gay, bisexual or as being on the down low, come to use the down low label and what it means to them to be on the down low.  相似文献

This paper follows the tradition of treating Zhuangzi's Butterfly Dream episode as presenting a version of skepticism. However, unlike the prevalent interpretations within that tradition, it attempts to show that the skepticism conveyed in the episode is more radical than it has been conceived, such that the episode can be read as a skeptical response to Descartes’ refutation of skepticism based on the Cogito, ergo sum proof. The paper explains how the lack of commitment in Zhuangzi to the dubious assumption about ‘I’ that it necessarily refers to something existing to which Descartes seems to uncritically adhere allows Zhuangzi to doubt what for Descartes is absolutely indubitable: I exist.  相似文献
