Abstract It is increasingly easy to acquire a large amount of data about problem before formulating hypothesis. The idea exploratory analysis (EDA) predates this situation, but many researchers find themselves appealing EDA as an explanation what they are doing with these new resources. Yet there has been relatively little explicit work on or why it might be important. I canvass several positio...
Anticipated reward magnitude and probability comprise dual components of expected value (EV), a cornerstone of economic and psychological theory. However, the neural mechanisms that compute EV have not been characterized. Using event-related functional magnetic resonance imaging, we examined neural activation as subjects anticipated monetary gains and losses that varied in magnitude and probabi...
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
In the best case using an abstraction hierarchy in problem solving can yield an exponential speed up in search e ciency Such a speed up is predicted by var ious analytical models developed in the literature and e ciency gains of this order have been con rmed empir ically However these models assume that the Down ward Re nement Property DRP holds When this property holds backtracking never need ...
