Perceptual judgments result from a dynamic process, but little is known about the dynamics of number-line estimation. A recent study proposed a computational model that combined a model of trial-to-trial changes with a model for the internal scaling of discrete numbers. Here, we tested a surprising prediction of the model—a situation in which children's estimates of numerosity would be better than those of adults. Consistent with the model simulations, task contexts led to a clear developmental reversal: children made more adult-like, linear estimates when to-be-estimated numbers were descending over trials (i.e., backward condition), whereas adults became more like children with logarithmic estimates when numbers were ascending (i.e., forward condition). In addition, adults’ estimates were subject to inter-trial differences regardless of stimulus order. In contrast, children were not able to use the trial-to-trial dynamics unless stimuli varied systematically, indicating the limited cognitive capacity for dynamic updates. Together, the model adequately predicts both developmental and trial-to-trial changes in number-line tasks. 相似文献
Language use in social contexts plays a central role in the thinking of philosophers and social scientists. Evidence is presented that suggests that the anthropologist Bronislaw Malinowski influenced Ludwig Wittgenstein on the contexted use of language. It is also proposed that non-Western peoples have been a heuristic for Western thinkers on epistemological matters. 相似文献
Over the past two decades, researchers consistently demonstrated the importance of science teaching approaches and student self-efficacy in influencing their science achievement. These findings have become the foundation of science education reform. However, empirical supports of these relationships are limited to direct relationships and small-scale studies. Therefore, little is known about the mechanism of how teaching approaches and student self-efficacy affect student achievement. In order to fill these gaps, this study used a multilevel structural equation modeling approach to analyze the direct and indirect relationships between teaching approaches, student self-efficacy, and science achievement by using the data of US eighth grade students in the 2011 TIMSS assessment. The results indicated that none of the teaching approaches identified in this study were directly associated with student science achievement, but significant mediation effect was found between generic teaching and student science achievement through student self-efficacy. Implications of these results for US educational system and reform were discussed.
In this paper I argue that Frank Jackson’s Knowledge Argument is better considered not as an argument against physicalism,
but as an argument that objective theories must be incomplete. I argue that despite the apparent diversity of responses to
the knowledge argument, they all boil down to a response according to which genuine epistemic gains are made when an individual
has an experience. I call this the acquaintance response. I then argue that this response violates an intuitive stricture
on the objectivity of theories. Therefore, the knowledge argument does show that objective theories cannot provide a complete
understanding of the world. The result, however, is that both objective dualism and objective physicalism are refuted by the
argument. In the end it is suggested that the notion of “subjective physicalism” is one that should be pursued. 相似文献
