Although the Rescorla-Wagner model is widely taught in learning courses, most textbooks present a simplified version that does not contain all of its parameters. On the basis of Rescorla and Wagner 1972) and the Turbo PASCAL program by Lachnit, Schneider, Lipp, and Kimme! (1988), we created a simulation using STELLA-II, an icon-based program by High Performance Systems, Inc. We argue that this simulation facilitates teaching the complete Rescorla-Wagner model. Using trans-switching (Kimmel & Ray, 1978; Lachnit, 1986; Murrin & Kimmel, 1986) as an example, we demonstrate the effectiveness of the STELLA-II version of the Rescorla-Wagner model as a heuristic tool. 相似文献

The Impact of Procedural Justice on Opinions of Public Policy: Solid Waste Management as an Example1
This study assessed the applicability of Tyler and Lind's (1992) relational model of authority to the context of local government policies on solid waste management. Tests of the hypothesized relations proposed by Tyler and Lind, accomplished through structural equation modeling, revealed that our data supported the relations between the various constructs of the model. Perceptions of both process control and relational process were found to be positively related to procedural fairness judgments, while procedural fairness judgments were weakly related to evaluations of government entities. Contrary to our expectations, a similar structural equation model test of an extension of the Tyler and Lind model showed that the model constructs were unrelated to respondents' opinions of public policies. The results also indicated that respondents living in communities with different infrastructures and political climates differed slightly in their perceptions of procedural justice and related constructs, but did not differ in their endorsement of the various solid waste management policies. 相似文献

A multiple component strategy was investigated for aiding staff responsible for supervising production of lower functioning retarded clients on contract tasks in an institution-based sheltered workshop. The strategy was assessed in a combined multi-element, multiple baseline across groups design with a reversal component. Production performance increased during the production supervisory strategy with all 16 clients, with the range of increase varying from a few percentage points to 150% of baseline production. Both the clients and staff (responsible for conducting the research) preferred working under experimental conditions rather than under baseline conditions which approximated those found in “typical” sheltered workshops. 相似文献

Perception is shown in a block diagram which includes the instrumental errors in the sensing device, the transmission distortion in the nerves and the perceptual misjudgment in the high center. The perceptual misjudgment originates from the variation of comparison standards and the method of comparison, and would correspond to the mis-programming of the computer. A general mathematical formula for perception under the influence of various background stimuli is presented. The mechanism and equation for predicting the Ebbinghaus illusion are also presented. 相似文献

The availability of a specific category of closed class items (prepositions) was examined in Broca's and Wernicke's aphasia. The role of prepositions was varied (syntactic/semantic) in two tasks: one requiring production of prepositions and the other acceptability judgments. Overall, it was easier to perform the acceptability task than to produce the target item. In the judgment task, Wernicke's aphasics more accurately determined the acceptability of prepositions in their syntactic role than in their semantic role, but Broca's aphasics showed no such difference. In the production task, Wernicke's aphasics again were more likely to produce prepositions which were in a primarily syntactic role. Broca's aphasics, however, failed to produce such syntactically based prepositions. The results suggest that the availability of a given closed class vocabulary form is not merely a function of its class membership but also of its functional role, and this fact serves to distinguish aspects of Broca's and Wernicke's aphasics' deficit. 相似文献

Computerized classification testing (CCT) aims to classify persons into one of two or more possible categories to make decisions such as mastery/non-mastery or meet most/meet all/exceed. A defining feature of CCT is its stopping criterion: the test terminates when there is enough confidence to make a decision. There is abundant research on CCT with a single cut-off, and two common stopping criteria are the sequential probability ratio test (SPRT) statistic and the generalized likelihood ratio statistic (GLR). However, there is a relative scarcity of research extending the SPRT to the multi-hypothesis case for when there is more than one cut-off. In this paper, we propose a new multi-category GLR (mGLR) statistic as well as a stochastically curtailed version of the CCT with three or more categories. A simulation study was conducted to show that the mGLR statistic outperformed the existing stopping rules by generating shorter average test length without sacrificing classification accuracy. Results also revealed that the stochastically curtailed mGLR successfully increased test efficiency in certain testing conditions. 相似文献

基于生态系统理论和认知易感性模型,本研究拟探讨初中生亲子关系对抑郁的影响及作用机制,采用问卷法对813名初中生进行调查。结果表明:(1)亲子关系、自尊、情绪弹性与抑郁之间呈两两显著相关,且亲子关系能显著负向预测抑郁;(2)自尊和情绪弹性在亲子关系与抑郁之间起显著的中介作用,具体包括三条路径:一是自尊的单独中介作用;二是情绪弹性的单独中介作用;三是自尊和情绪弹性的序列中介作用。本研究揭示了初中生亲子关系通过内在心理因素对抑郁水平产生影响的作用机制,为进一步提升初中生的心理健康提供了指导性建议。 相似文献
