A corpus of phonological errors produced in narrative speech by a Wernicke's aphasic speaker (R.W.B.) was tested for context effects using two new methods for establishing chance baselines. A reliable anticipatory effect was found using the second method, which estimated chance from the distance between phoneme repeats in the speech sample containing the errors. Relative to this baseline, error-source distances were shorter than expected for anticipations, but not perseverations. R.W.B.'s anticipation/perseveration ratio measured intermediate between a nonaphasic error corpus and that of a more severe aphasic speaker (both reported in Schwartz et al., 1994), supporting the view that the anticipatory bias correlates to severity. Finally, R.W.B's anticipations favored word-initial segments, although errors and sources did not consistently share word or syllable position. 相似文献

该研究考察了多媒体动画片语境条件下,词类对儿童英语词汇学习效果的影响,结果发现:(1)儿童对名词和形容词的再认成绩显著优于代词;(2)就独立回忆测验而言,名词的成绩显著高于代词,形容词的成绩处于代词和名词之间,但与二者的差异均不显著;(3)就情境回忆测验而言,名词与形容词的成绩差异不显著,二者均显著高于代词;(4)名词与形容词的情境回忆测验成绩均显著高于独立回忆测验成绩,但代词的独立回忆与情境回忆测验成绩差异不显著。总体而言,儿童对名词和形容词的学习效果好于代词,表明词类会对儿童英语词汇学习效果产生影响。 相似文献

Speech acts and arguments 总被引:2,自引:0,他引:2
Scott Jacobs 《Argumentation》1989,3(4):345-365
Speech act theory seems to provide a promising avenue for the analysis of the functional organization of argument. The theory, however, might be taken to suggest that arguments are a homogenous class of speech act with a specifiable illocutionary force and a single set of felicity conditions. This suggestion confuses the analysis of the meaning of speech act verbs with the analysis of the pragmatic structure of actual language use. Suggesting that arguments are conveyed through a homogeneous class of linguistic action overlooks the way in which the context of activity and the form of expression organize the argumentative functions performed in using language. An alternative speech act analysis would treat folk terminology as a heuristic entry point into the development of a technical analysis of the myriad argumentative functions and structures to be found in natural language use. This would lead to a thorough-going pragmatic analysis of the rational and functional design of speech acts in argumentation. 相似文献

Pigeons were trained on a multiple schedule in which two target components with identical reinforcement schedules were followed by either the same-valued schedule or by extinction. Response rate increased in both target components but was higher in the target component followed by extinction, replicating previous findings of positive anticipatory contrast. A similar design was used to study negative contrast, in that the two target components were followed either by the same-valued schedule or by a higher valued schedule. Negative contrast occurred equally, on average, in both target components, thus failing to demonstrate negative contrast that is specifically anticipatory in nature. When the stimuli correlated with the two target components were paired in choice tests, the pattern of preference was in the opposite direction. For the positive contrast procedure, no significant preference between the two target stimuli was evident. But for the negative contrast procedure, preference favored the stimulus followed by the higher valued schedule. The results demonstrate a functional dissociation between positive and negative contrast in relation to stimulus value. More generally, the results demonstrate an inverse relation between response rate and preference and challenge existing accounts of contrast in terms of the concept of relative value. 相似文献

题材个体化和问题重述两策略的效果研究 总被引:1,自引:0,他引:1
探讨题材个体化和问题重述作为两种解题策略在解决加、减法应用题中的有效性,采用了4种策略类型×3种数学能力水平×2种问题题材×2种题材情境与解题操作关系的四因素混合设计。结论如下:学生基本上能够独立进行题材个体化和问题重述;在本实验条件下,水平高的学生,运用不同策略没有差异;水平中等的学生运用双策略、水平低的学生运用双策略以及题材个体化策略均产生了积极效果;题材个体化策略对于解决不熟悉题材的应用题将产生积极效果,运用以上两策略解决问题情境与解题操作相矛盾的问题没有帮助。除了应用题陈述图式以外,本实验证明还存在着应用题结构图式;可把题材个体化和问题重述作为解题策略教给学生运用。 相似文献

Whorf and Wittgenstein are perhaps the most famous names in linguistics and philosophy associated with the assumption that language plays a decisive role in shaping our view of reality. After a critical discussion of Whorf's linguistic relativity principle I conclude that it is not language as a system, but the use of language according to the rules of language games which connects language thought and world view, especially if some particular usage becomes the commonly accepted norm. This traditional norm also enters argumentative discourse in the form of background assumptions occuring in the premises of arguments. Thus, traditional points of view and prevailing ideologies in a society, even if challenged in discussions, can become reinforced and stabilized. This is illustrated with a critical analysis of the role and function of tautological utterances in argumentative discourse, which only apparently are compelling means of argumentation. 相似文献

This study examines the effects of perceived group context on subjects risk attitudes and their sensitivity to the framing of choice outcomes in a ‘life-death’ decision problem. It seeks to uncover the psychological mechanisms underlying decision-making biases by systematically manipulating the decision context in which the ‘life-death’ problem was described. The study revealed that subjects risk preferences varied as a function of the experimental manipulations. Previously observed reversals in preferences (framing effects) appeared in large-group contexts and disappeared in small-group and family contexts. When considering the fate of small groups, subjects unambiguously favored the probabilistic outcome, no matter how the ‘life-death’ decision problem was framed. The empirical data obtained from the present study suggest that human choice patterns are behaviorally distinguishable across large-group, small-group, and family social contexts. 相似文献

Drawing on the work of Ludwig Wittgenstein and his own experience as a therapist and educator/trainer, the author describes some of the issues involved in helping therapists to find their way out of various muddles and mazes that are deeply embedded in language. 相似文献

The interpretation of discourse covers a continuum with two extremes: on the one hand, a text considered as an ideal, distant object, and on the other hand, a conversation regarded as a real, present event. On the basis of a distinction between relatively context-invariant propositions and relatively context-dependent statements, it is argued that statements in conversational discourse are easier to interpret than statements in texts, whereas only propositions in symbolic logic can be interpreted with exactitude. In the same way, the interpretation of dialogical arguments proceeds more easily than the interpretation of arguments in texts. While dialogical argumentation requires a dialectical approach, textual argumentation necessitates an imaginative reconstruction of the argument. From this it can be concluded that for different sorts of argumentative discourse diverse sorts of interpretative activities have to be used. 相似文献

AbstractIn this study we explored why there are sometimes conflicting findings regarding the influence of past sexual experience on relationships. Consequently, we studied the effects of body-esteem and religiosity on sexual experience in two relational contexts (casual or committed relationships) and how all of these variables were associated with life satisfaction, and the likelihood that a person would be married by their early thirties. With a national sample of 4966 participants, our results indicated that sexual experiences in casual relationships had negative associations with life satisfaction and relationship status, whereas sexual experiences in committed relationships had positive associations. 相似文献
