In four Pavlovian conditioned lick-suppression experiments, rats had two conditioned stimuli (CSs X and A) independently paired with footshock, followed by pairings of a compound of A and X with the footshock. On subsequent tests with CS X, less conditioned suppression was observed than in control subjects that lacked the compound AX→footshock trials. Thisoverexpectation effect was reversed through posttraining extinction of CS A, a result consistent with both performance- and acquisition-focused models of retrospective revaluation. However, only performance-focused models could account for how posttraining increases or decreases in the A-footshock temporal interval attenuate the overexpectation effect.  相似文献

The rationale was to apply Piaget’s theory and methods to the study of the phylogenetic development of cognitive abilities. It was asked whether squirrel monkeys have the prerequisite skills for conservation of quantity, and, specifically, whether they might respond differentially to equivalent and unequivalent volumetric cues. All monkeys responded significantly and differentially to pairs of identical objects or pairs of objects similar only in volume vs. pairs of objects which differed in volume. It was concluded that squirrel monkeys have the prerequisite skills for the conservation of quantity. Discussion included methodological problems associated with demonstrating conservation in nonhumans as well as the potential usefulness of Piaget’s theory for phylogenetic studies of intelligence.  相似文献

Conclusion The Strategic Impact Model is distinctive in its portrayal of the integration of instructional and non-instructional interventions and its suggestion that all performance interventions undergo an analysis-design-development-production cycle, just as instruction does. It also differs from other similar models in its use of evaluative activities at each stage to assure alignment with strategic needs as well as quality control, and its suggestions for improving the chances of successful implementation by carrying out change management activities at each phase of the development process. He has special interests in distance education, historical and philosophical foundations of instructional technology and instructional development processes. He has special interests in planning and evaluating performance improvement initiatives, including training. An erratum to this article is available at .  相似文献

We examined the implementation of a laser-disk based science curriculum in an elementary school. The goal was to develop a richer understanding of the principles for designing a curriculum that will adequately support teachers in adopting a learner-centered framework. Issues included: who has ownership of the classroom discussion; what types of activities are engaged in terms of the constraints imposed; and what is the teacher's response to the specific tools provided (the teacher's guide, the Circle of Learning, and concept maps). In addition to looking at the implementation pattern, we also examined the impact of the implementation on student attitudes and anxiety toward science. Results indicated little adoption of the curriculum, and teachers continued to maintain a high degree of control in the classroom. However, results also indicated significant effects of the curriculum on science attitude and anxiety. Suggestions for future research are included.  相似文献

Following the trend of consequential accountability in US public education, New York City introduced a teacher evaluation program during the 2013–2014 school year that linked teachers’ individual performance ratings with their students’ exam scores. As this program systemically alters the nature of teacher–student relationships by transforming students into the means to an end (teachers’ professional viability), this study investigated the implementation of this accountability program from the point of view of the teachers – those who were the subject of this new policy. This study of 15 teachers’ narratives from 3 distinct schools illuminates a social-organizational process that I refer to as mediated institutional assault – a perceived attack on the teachers’ sense of personhood and moral agency perpetrated by mediating figures whose actions were facilitated by bureaucratic policies and institutionally coordinated tools of control. Thus, this study reveals that the consequence of this new mode of accountability is not merely the threat of losing one’s job, but also an insidious form of psychological assault, which in its masked delivery violates teachers’ sense of relational morality and challenges deeply engrained beliefs about their role as educators.  相似文献
