Medical education as moral formation: an Aristotelian account of medical professionalsim.

The medical professionalism movement, bolstered by many influential medical organizations and institutions, has in the last decade produced a number of conceptual definitions of professionalism and a number of concrete proposals for its measurement and teaching. These projects, however laudable, are misguided when they treat professionalism as a unitary descriptive concept rather than as a contested and therefore primarily evaluative one; when they conceive professionalism as a domain of medical practice separable in principle from other domains; and when they treat professionalism as, in principle, a specifiable goal or product of sufficiently well designed educational curricula. The logic of professionalism-as-product corresponds to the logic of techne (art or practical skill) in Aristotle's Nicomachean Ethics. Aristotle provides a cogent argument, however, that the moral excellences denoted by "professionalism" cannot be "produced" or even prespecified in the concrete; rather, they must be acquired through long practice under the careful concrete guidance of teachers who themselves embody these moral excellences. Phronesis (practical wisdom) rather than techne must therefore be the guiding logic of educational initiatives in medical professional formation, with particular emphasis on close mentorship and on the moral character both of students and of those who teach them.

Learning from falling.

Walkers fall frequently, especially during infancy. Children (15-, 21-, 27-, 33-, and 39-month-olds) and adults were tested in a novel foam pit paradigm to examine age-related changes in the relationship between falling and prospective control of locomotion. In trial 1, participants walked and fell into a deformable foam pit marked with distinct visual cues. Although children in all 5 age groups required multiple trials to learn to avoid falling, the number of children who showed adult-like, 1-trial learning increased with age. Exploration and alternative locomotor strategies increased dramatically on learning criterion trials and displays of negative affect were limited. Learning from falling is discussed in terms of the immediate and long-term effects of falling on prospective control of locomotion.

The abstraction of form in semantic categories.

Undergraduates were asked to generate a name for a hypothetical new exemplar of a category. They produced names that had the same numbers of syllables, the same endings, and the same types of word stems as existing exemplars of that category. In addition, novel exemplars, each consisting of a nonsense syllable root and a prototypical ending, were accurately assigned to categories. The data demonstrate the abstraction and use of surface properties of words.
