Two experiments with goldfish were performed to investigate the role of stimulus-reinforcer vs. response-reinforcer relationships in omission training and the role of stimulus localizability in a positive behavioral contrast paradigm. The directed behavior of fish, like that of pigeons and rats in other studies, was greatly influenced by positive stimulus-reinforcer correlations, as evidenced by maintained contacts of a signal for food, even though such responses terminated the signal and cancelled reinforcement delivery. Goldfish exhibited positive behavioral contrast when the signals for reinforcement and nonreinforcement were displayed directly on the response key, but no contrast was observed when variations in a diffuse houselight stimulus were used as signals for reinforcement or nonreinforcement. Analysis of sequential-trial data yielded effects analogous to Pavlovian positive and negative induction. Theoretical and methodological problems were briefly considered. 相似文献

The Schmid‐Leiman decomposition of a hierarchical factor model converts the model to a constrained case of a bifactor model with orthogonal common factors that is equivalent to the hierarchical model. This article discusses the equivalence and near‐equivalence of the hierarchical and bifactor models and the implications of the difficulty of distinguishing between these models because of low power in samples commonly found in academic research. 相似文献

After one year of implementation, this paper describes a programme designed to support literacy learning in low performing schools from poor sectors in Santiago, Chile. School‐based intensive training on theory and practice of a literacy learning framework for classroom instruction and long‐term support were used to impact the achievement of students from disadvantaged families in 16 kindergarten classrooms and 16 1st‐grade classrooms in nine primary schools. Preliminary results showed an improvement in learning achievement positively related to level of implementation of the literacy instruction framework in the classrooms and teachers' perception of an improvement in their knowledge and classroom practices. Although findings from this study cannot support definite conclusions, because of the lack of experimental conditions, they provide relevant information for future experimental studies on how to meet the literacy learning needs of children from disadvantaged backgrounds. 相似文献

The 1919 eclipse expedition's confirmation of general relativity is often celebrated as a triumph of scientific internationalism. However, British scientific opinion during World War I leaned toward the permanent severance of intellectual ties with Germany. That the expedition came to be remembered as a progressive moment of internationalism was largely the result of the efforts of A. S. Eddington. A devout Quaker, Eddington imported into the scientific community the strategies being used by his coreligionists in the national dialogue: humanize the enemy through personal contact and dramatic projects that highlight the value of peace and cooperation. The essay also addresses the common misconception that Eddington's sympathy for Einstein led him intentionally to misinterpret the expedition's results. The evidence gives no reason to think that Eddington or his coworkers were anything but rigorous. Eddington's pacifism is reflected not in manipulated data but in the meaning of the expedition and the way it entered the collective memory as a celebration of international cooperation in the wake of war. 相似文献
