As Web_2.0 technologies redefine the learning space, apprehension in the adult learner toward technology and alternative instruction could represent a significant barrier to an effective teaching and learning experience. Although tolerance for ambiguity has been highlighted as important in the development of creative, integrative thinking in the college setting, few studies have examined ambigu...

We build a general equilibrium model of occupation choice, where the risks inherent in a technology embodying a new innovation are only vaguely known (ambiguous), whereas the old technology has known risks. Using the Arrow-Hurwicz criterion to characterise decisionmaking in the face of ambiguity, we distinguish agents according to their degree of ambiguity aversion. Equilibrium requires that al...

Despite widespread interest in ambiguity tolerance and other information-related individual differences, existing measures are conceptually dispersed and psychometrically weak. This paper presents the Spanish version of MSTAT-II, a short, stimulus-oriented, and psychometrically improved measure of an individual's orientation toward ambiguous stimuli. Results obtained reveal adequate reliability...

Background Physicians' tolerance of uncertainty (TU) is a trait potentially associated with desirable outcomes, and emerging evidence suggests it may change over time. Past studies of TU, however, have been cross-sectional and have not measured tolerance of the different, specific types of uncertainty that physicians confront. We addressed these limitations in a longitudinal exploratory study o...
