Maintaining the anonymity of cadavers in medical education: Historic relic or educational and ethical necessity?

Throughout the modern history of anatomical dissection by medical and other health science students, cadavers have been anonymized. This has meant that students have been provided with limited, if any, information on the identities or medical histories of those they are dissecting. While there was little way around this when the bodies were unclaimed, this need not be the case when the bodies have been donated. However, with a few exceptions, no efforts have been made to change this model. Recent attempts to move anatomy teaching in a more humanistic direction, by emphasizing the cadaver as the students' first patient and with the growth of commemoration services following the dissecting process, raise the question of whether cadavers should continue to be anonymized. In laying a basis for discussion of this matter, we outline what appear to be the virtues of anonymity, and the form that alternatives to anonymity might take. The options identified are nonidentification, low information; nonidentification, moderate information; and identification, full information. The virtues and drawbacks of each of these possibilities are assessed by analyzing their value for students, and also for donors and their families. Policy issues raised by alternatives are also considered. This article provides a basis for continued discussion and suggestions for further research in this area.

Acquiring Color Names via Linguistic Contrast: The Influence of Contrasting Terms

Linguistic contrast of the form "It's not X; it's Y" is often used by adults to correct children's naming errors. The present studies examined whether such linguistic contrast could help preschoolers learn a novel color name. In Experiment 1, a novel color term was contrasted only once with 1 or 2 familiar color names. Contrasting a new color term with children's own label for the stimulus color helped 5-year-olds learn the new term, but contrasting the new term with randomly chosen familiar color terms did not. For 4-year-olds, neither kind of contrast helped much. Experiments 2 and 3 showed that when the contrastive information was presented more than once, even 3- and 4-year-olds performed much like the 5-year-olds in Experiment 1. Together, these findings suggest that contrasting a new term with a child's own term facilitates the acquisition of the new term, perhaps because it gives the child specific information about how two terms are related in meaning.     

Testing the Effect of Meat Tenderizer on Human Hair: A Class Project for Nonscience Majors

Use of a commercially available meat tenderizer, a source of an enzyme which can degrade meat protein, was used in a take-home class experiment. Students were asked to test the effects of incubating (their own) human hair in water with and without this enzyme. Students were surprised to see little or no effect of the enzyme on their own hair sample. They were also surprised that there was so much variation in the results (observations). From this experiment, students developed a much better understanding of the scientific method and the importance of experimental controls.     

Singaporean and Australian Students' Understanding of Vision

A model for the development of an understanding of how people see has been proposed on the basis of a questionnaire and interview study of a cross-section of Australian school students. The model, based on the SOLO model of cognitive development (Collis & Biggs, 1991), involves the building of connections between the eye, light and the object seen in the Ikonic and Concrete Symbolic modes of cognitive functioning. In order to assess the viability of the model across cultures, the questionnaire was administered to 116 primary and secondary school students in Singapore. This paper reports some details of how the model was supported in its most important respects. The few discrepancies might be explained in terms of environmental, linguistic and/or teaching factors.     

Using communication to manage uncertainty about cervical cancer screening guideline adherence among Appalachian women

Changes to the United States Preventive Services Task Force (USPSTF) recommendations for cervical cancer preventive services have led to patient confusion, especially in medically underserved populations. We investigated how patient uncertainty concerning cervical cancer screening guidelines is appraised and managed through communication with healthcare providers by conducting in-depth, face-to-face interviews with 24 adult women between the ages of 24 and 65 (m?=?41, SD?=?14) living in Appalachia Kentucky. In general, participants expressed a high degree of uncertainty about the updated cervical cancer screening guidelines and appraised this uncertainty as both a danger and an opportunity. Communication with healthcare providers served both to exacerbate and to mitigate patient uncertainty. The study identifies how healthcare providers may use the change in USPSTF guidelines as a “teachable moment” to productively counsel patients on the importance of timely screening, the typical progression of certain types of high-risk HPV (human papillomavirus) infection to cervical cancer, and the importance of follow-up care.     

Object Properties and Knowledge in Early Lexical Learning

The ease with which young children learn object nouns suggests that they possess strategies to identify properties critical to lexical category membership. In previous work, young children used a same-shape criterion to extend new count nouns. The present research tested the generality of this shape bias. 2- and 3-year-olds were asked either to extend a novel count noun to new instances, or to choose unnamed objects to go together. The objects varied in shape, size, and texture. For half of the subjects, the objects had eyes--a property strongly associated with certain material kinds. If young children know this association, they should attend to texture as well as shape in classifying objects with eyes. With named objects only, both 2- and 3-year-old children classified eyeless objects by shape and objects with eyes by both shape and texture. The results suggest that very young children possess considerable knowledge about conditional relations between kinds of perceptual properties. Knowledge of such conditional relations may aid children in forming new categories and thus in discovering new word meanings.
