代词的指代在语篇局部连贯性中具有关键作用。中心理论是代词指称中的重要理论,它解释了语篇中代词的分布规律;注意驱动理论是在中心理沦的基础上结合重音预设解释重音或非重音代词。影响代词指称的因素有语义因素和结构因素。对代词的认知研究另一方面主要集中在对歧义代词的解释.对歧义代词的解释的研究一方面采用重复姓名不利实验范式,另一方面的研究采用的研究方法是探测词任务。在汉语中对代词的研究主要是对文本语篇的研究。 相似文献

This study reexamined the association between speech rate and memory span in children from kindergarten to sixth grade (N = 152) in order to potentially account for the inconsistencies within the published literature on this topic. Some of the inconsistencies in past research may reflect the different methods adopted in assessing speech rate. In particular, repeating word triples may itself involve memory demands, contaminating the correlation between speech rate and memory span in younger children. Analyses using composite speech rate and memory span measures showed that speech rate for word triples shared variance with memory span that was independent of speech rate for single words. Moreover, speech rate for word triples was largely redundant with age in explaining additional variation in memory span once the effects of speech rate for single words were controlled. 相似文献

The development of a translation of Mehrabian and Russell's scales for the measurement of pleasure, arousal and dominance from the original English to a Spanish version for use in Venezuela is described. The translated scales were administered to two samples of middle‐class Venezuelan consumers (n = 127,n = 127) between the ages of 20 and 50, among whom males and females were represented approximately equally. Internal reliability (measured by Cronbach's alpha) and scale validity (measured by factor analysis) indicate that the translated scales are suitable for consumer and other social psychological research in Spanish.

视知觉组织在整体知觉中的作用--脑损伤病人的实验研究 总被引:1,自引:0,他引:1
本实验研究大脑损伤如何影响复合图形的整体知觉。三例病人脑损伤部位分别在大脑枕区、顶区、颞区、额区及基底节和豆状核。复合图形被呈现给病人和正常对照被试。强迫选择识别等任务表明,当空间相邻性决定局部图形的知觉组织时,病人识别整体性质的正确率高于(ZD和FL)或略底于(GK)识别局部性质的正确率;当形状相似性决定局部图形的知觉组织时,病人识别整体性质的正确率显著降低,而识别局部性质的正确率受到的影响较小。在同样的任务中正常被试识别整体和局部性质的正确率受知觉组织因素的影响很小。这些结果提示大脑损伤对整体知觉的破坏可能主要通过影响基于形状相似性的知觉组织实现。 相似文献

The present study assessed the effects of guided notes on student responding and accuracy of recall of lecture material in an undergraduate psychology class using multi-element design. Guided notes were administered for approximately half of the class sessions on a random schedule. Data were collected on the frequency of student responses and daily quizzes were administered to assess accuracy of recall of information presented in the lecture. Results indicated higher mean quiz scores and response frequencies during the guided notes condition. Social validity questionnaires administered to participants revealed satisfaction with results and procedures. 相似文献

Handling Locally Stratified Inconsistent Knowledge Bases 总被引:1,自引:0,他引:1
This paper investigates the idea of reasoning, in a local (or contextual) way, under prioritized and possibly inconsistent knowledge bases. Priorities are not supposed to be given globally between all the beliefs in the knowledge base, but locally inside sets of pieces of information responsible for inconsistencies. This local stratification offers more flexibility for representing priorities between beliefs. Given this local ordering, we discuss five basic definitions of influence relations between conflicts. These elementary notions of influence between two conflicts A and B exhaustively explore the situations where solving A leads to solve B. Then we propose natural approaches to restore the coherence of a knowledge base on the basis of influence relations between locally-stratified conflicts. 相似文献

This paper is about the Linear Logistic Test Model (LLTM). We demonstrate that there are infinitely many equivalent ways to specify a model. An implication is that there may well be many ways to change the specification of a given LLTM and achieve the same improvement in model fit. To illustrate this phenomenon, we analyze a real data set using a Lagrange multiplier test for the specification of the model. This Lagrange multiplier test is similar to the modification index used in structural equation modeling. 相似文献

Pigeons were exposed to a repeated acquisition procedure in which no delays were imposed and rate of responding was relatively high. They also were exposed to conditions in which delays were arranged between trials within chains or between completed chains, and rates of responding were lower. Number of trials, rate of reinforcement, difficulty of the discrimination, and motivating operations were held constant. Terminal accuracy was highest under the no‐delay condition, in which rate of responding was highest. Effects of trial spacing on retention were mixed and depended on whether delays were imposed between trials within chains or between completed chains. These findings provide basic‐research support for the rapid presentation of trials in direct instruction and for rate building in precision teaching. 相似文献

Five pigeons responded on steady-state concurrent variable-interval variable-interval schedules of food presentation in which half of the foods were removed and replaced with nonfood stimuli. Across conditions, the stimuli were either paired or unpaired with food, and the correlation between the ratio of food deliveries on the two alternatives and the ratio of nonfood stimuli was either −1, 0, or +1. Neither the pairing of stimuli with food, nor the correlation between stimuli and food, affected generalized-matching performance, but paired stimuli had a demonstrable effect at a local level of analysis. This effect was independent of the food–stimulus correlation. These results differ from results previously obtained in a frequently changing environment. We attribute this difference in results to differences in the information value of response-contingent stimuli in frequently changing versus relatively constant environments, as well as to differences between forward pairing and simultaneous pairing of the stimuli with food. 相似文献
