Formal Schooling Influences Two- but Not Three-Dimensional Naming Skills

The modulatory influence of literacy on the cognitive system of the human brain has been indicated in behavioral, neuroanatomic, and functional neuroimaging studies. In this study we explored the functional consequences of formal education and the acquisition of an alphabetic written language on two- and three-dimensional visual naming. The results show that illiterate subjects perform significantly worse on immediate naming of two-dimensional representations of common everyday objects compared to literate subjects, both in terms of accuracy and reaction times. In contrast, there was no significant difference when the subjects named the corresponding real objects. The results suggest that formal education and learning to read and to write modulate the cognitive process involved in processing two- but not three-dimensional representations of common everyday objects. Both the results of the reaction time and the error pattern analyses can be interpreted as indicating that the major influence of literacy affects the visual system or the interaction between the visual and the language systems. We suggest that the visual system in a wide sense and/or the interface between the visual and the language system are differently formatted in literate and illiterate subjects. In other words, we hypothesize that the pattern of interactions in the functional-anatomical networks subserving visual naming, that is, the interactions within and between the visual and language processing networks, differ in literate and illiterate subjects.     

A Debate on the Ethics of Aging: Does the Concept of Autonomy Provide a Sufficient Framework for Aging Policy?

This article presents a debate on the issue of autonomy in aging policy held at the 1994 annual meeting of the American Society on Aging held in San Francisco, California. Harry R. Moody, director of the Institute for Human Values in Aging at Hunter College, supports a reconceptualized notion of personal autonomy which focuses on issues of power, theory, and practice, and finds conflicts between autonomy and justice in the lived world of the elderly and disabled. In aging policy, he promotes an emphasis on social movements such as Hospice rather than on autonomy of individuals. He suggests alternatives to extreme paternalism or complete autonomy, such as a communicative ethics approach. Larry Polivka, director of the Florida Policy Exchange Center on Aging at the University of South Florida, affirms that policy for the aging and disabled should be based ona commitment to autonomy. He describes an integrated model for long-term care that places autonomy first and includes features of communicative ethics and the negotiated consent and virtues models of ethics.     

Should Marxists care about alienation?

Conclusion We have found that a sparse version of the claim that alienated labor is a bad thing can inform a political morality without turning that morality into one which makes more comment on people's ends than the liberal can accept. We have also seen that a modification of the ideas of alienation from our species being can play a limited role in a liberal political morality, but that the rational kernel of the critique from species alienation is already a familiar part of the liberal tradition. However, the substantive view of the good life - as one which essentially involves engagement in communal ties and satisfying labor - cannot play the role which certainly many Marxists would like it to play in their critique of capitalism, at least if their critique is to be recognizably liberal.Why should it matter so much that Marxists be able to accommodate central liberal insights? It is not because a political morality has to be liberal in order to be successful in the real world: history and the contemporary world are full of examples of political views which command wide assent despite (or because of) their illiberality. But the foreseeable stages of a socialist society will be plagued by the circumstances of justice as they have been classically conceived. A socialism which is sufficiently better than capitalism to be worth the significant risk and sacrifice it is likely to require must be liberal in the sense that it can be regarded as defensible to each person who is actually subject to it. This does not require that it accommodate the greed of the greedy or the injustice of the unjust. But it does require that it not presume the unworthiness of the moral commitments of its reasonable citizens.⁴⁷     

Use of a virtual reality car-driving stressor in cardiovascular reactivity research

Eighteen subjects (11 males, 7 females) completed a virtual reality car-driving stressor on two occasions several weeks apart. Immediately before and throughout task performance, blood pressure, cardiac output, and total peripheral resistance were assessed. Reactivity scores were calculated for each parameter for each subject as the arithmetic difference between task level and baseline level. The task elicited considerable hemodynamic activation on each occasion of testing, as well as high levels of self-reported task realism, engagement, excitement, and nervousness. Correlation analyses of both absolute and reactivity scores revealed evidence of test-retest reliability. Males were found to exhibit greater absolute levels of and greater increases in systolic blood pressure. The development of tasks suitable for inclusion in a battery of behavioral stressors, responses to which may help identify those at risk for later disease, is of considerable interest in cardiovascular behavioral medicine. The present findings suggest that the virtual reality car-driving task may be useful in this context.
