句子先提述的参与者在可提取性上的优势现象   总被引:6,自引:0,他引:6  
陈永明  崔耀 《心理学报》1994,27(2):113-120
下述五个实验就汉语句子成分(包括句子的参与者及其动作)的提述次序对其可提取性的影响进行了研究,结果表明:(1)句子先提述的参与者比后提述的参与者容易被提取,提述的次序对参与者的可提取性有明显影响。(2)先提述参与者的这种优势与句子呈现的方式有一定的关系。(3)在系列呈现的条件下,先提述参与者的易提取性与探测词呈现的延迟间隔有关。(4)在系列呈现的条件下,参与者以名词形式出现时,被试的反应速度较快,而参与者以名字的形式出现时,反应则较慢;在同时呈现的条件下这种差异基本消失。(5)句子参与者的行动(即句子的动词)的提述次序对其可提取性也有明显的影响,说明提述次序对句子成分的可提取性的影响,不只限于句子参与者本身。  相似文献

The main result of this paper is the following theorem: each modal logic extendingK4 having the branching property belowm and the effective m-drop point property is decidable with respect to admissibility. A similar result is obtained for intermediate intuitionistic logics with the branching property belowm and the strong effective m-drop point property. Thus, general algorithmic criteria which allow to recognize the admissibility of inference rules for modal and intermediate logics of the above kind are found. These criteria are applicable to most modal logics for which decidability with respect to admissibility is known and to many others, for instance, to the modal logicsK4,K4.1,K4.2,K4.3,S4.1,S4.2,GL.2; to all smallest and greatest counterparts of intermediate Gabbay-De-Jong logicsD n; to all intermediate Gabbay-De-Jong logicsD n; to all finitely axiomatizable modal and intermediate logics of finite depth etc. Semantic criteria for recognizing admissibility for these logics are offered as well.The results of this paper were obtained by the author during a stay at the Free University of Berlin with support of the Alexander von Humboldt Foundation in 1992 – 1993.Presented byWolfgang Rauntenberg  相似文献

This article reports on the factor structure of theScale to Assess World View (c) (SAWV). Alpha reliabilities for the factors are presented. Gender differences in world views are also explored to understand how men and women in this sample viewed the world. Recommendations for client assessment, therapy, education and training, and scale revision are discussed. The research reported here is based on a paper presented at the annual meeting of the American Psychological Association, Washington, DC, August 17, 1992.  相似文献

Increasingly, contemporary medical ethicists have become aware of the need to explicate a foundation for their various models of applied ethics. Many of these theories are inspired by the apparent incompatibility of patient autonomy and provider beneficence. The principle of patient autonomy derives its current primacy to a large extent from its legal origins. However, this principle seems at odds with the clinical reality. In the bioethical literature, the notion of authenticity has been proposed as an alternative foundational principle to autonomy. This article examines this proposal in reference to various existentialist philosophers (Heidegger, Sartre, Camus and Marcel). It is concluded that the principle of autonomy fails to do what it is commonly supposed to do: provide a criterion of distinction that can be invoked to settle moral controversies between patients and providers. The existentialist concept of authenticity is more promising in at least one crucial respect: It acknowledges that the essence of human life disappears from sight if life's temporal character is reduced to a series of present decisions and actions. This also implies that the very quest for a criterion that allows physicians to distinguish between sudden, unexpected decisions of their patients to be or not to be respected, without recourse to the patient's past or future, is erroneous.  相似文献

Carleton University, Ottawa, Ontariot Canada Confidence rating based calibration and resolution indices were obtained in two experiments requiring perceptual comparisons and in a third with visual gap detection. Four important results were obtained. First, as in the general knowledge domain, subjects were underconfident when judgments were easy and overconfident when they were difficult. Second, paralleling the clear dependence of calibration on decisional difficulty, resolution decreased with increases in decision difficulty arising either from decreases in discriminability or from increasing demands for speed at the expense of accuracy. Third, providing trial-by-trial response feedback on difficult tasks improved resolution but had no effect on calibration. Fourth, subjects can accurately reportsubjective errors (i.e., trials in which they have indicated that they made an error) with their confidence ratings. It is also shown that the properties of decision time, conditionalized on confidence category, impose a rigorous set of constraints on theories of confidence calibration.  相似文献

教师工作满意度的测量研究   总被引:100,自引:1,他引:99  
本研究运用一个"教师工作满意度量表",对北京、天津、大连及青岛等四省市的204名小学教师进行了测量,结果表明:(1)教师们在工作性质、职业投入感及人际关系这些内在因素上的满意度较高,而在薪水、领导管理、进修提升及物理条件这些外在因素上的满意度较低;(2)女教师的工作满意水平显著高于男教师;(3)从事"教师"这一职业的动机对教师的工作满意度有显著的影响。  相似文献

University students participated in one of four standard two-choice signal-detection experiments in which signal presentation probability was varied and the reinforcement distribution was held constant and equal. In Experiments 1, 3 and 4, subjects' performance showed a systematic response bias for reporting the stimulus presented least often. Experiments 1 and 4 showed that this effect was reliable with extended training and monetary, rather than point, reinforcement. In Experiment 2, all correct responses were signaled in some way, and this produced the opposite relationship between signal presentation probability and response bias. Experiments 1 and 3 found that explicitly deducting money (intended as punishment) for equal numbers of incorrect responses on each alternative, or varying the obtained overall rate of reinforcement, produced no clear change in response bias. The bias, shown by humans, for reporting the stimulus presented least often remains a challenge for theories of stimulus detection.  相似文献

Three psychological theories of psychosis are described, each of which has standing in psychiatry. Defined by the terms projection, double bind, and possession, they initially appear to have little or nothing in common to explain psychosis, but converge at four points: (1) A high degree of anxiety precipitated by a dilemma or conflict perceived to be unsolvable by the person; (2) the anxiety triggers a shift from one thought or motive in the direction of its opposite, because the original was believed too antagonistic to the wishes of significant others; (3) the opposite, in order to remain opposite, requires that the original thought or motive be forgotten, (4) a singular means to produce and reinforce forgetting is the interposition of psychiatric symptoms. In psychiatry today treatment would fit more consistently with the three theories taken as a whole rather than any one, and a rationale for this viewpoint is elaborated.  相似文献
