Introduction: Special Issue on Spirituality and Adult Development, Part III

This paper reviews the purpose of the three-part Special Issue on Spirituality and Adult Development, described in the Introduction to Special Issue Parts I and II (J. D. Sinnott, 2001, in press). It also outlines the contents of Part III. Developing adults express their belief that spirituality plays a key role in their development, and humanistic psychology supports this view, yet developmental psychologists have given comparatively little attention to this factor. Also the concept of spirituality seldom has been considered separately from that of religion. The purpose of this Special Issue is to begin to remedy this neglect and to begin to examine the meanings spirituality has for the developing adult. How might spirituality be adaptive? How might it relate to our connections with others and our society? This introduction is a summary of the five empirical and theoretical papers that form Part III of the Special Issue on Spirituality and Adult Development.

Absolute auditory thresholds in three Old World monkey species (Cercopithecus aethiops, C. neglectus, Macaca fuscata) and humans (Homo sapiens)

We investigated the absolute auditory sensitivities of three monkey species (Cercopithecus aethiops, C. neglectus, and Macaca fuscata) and humans (Homo sapiens). Results indicated that species-typical variation exists in these primates. Vervets, which have the smallest interaural distance of the species that we tested, exhibited the greatest high-frequency sensitivity. This result is consistent with Masterton, Heffner, and Ravizza's (1969) observations that head size and high-frequency acuity are inversely correlated in mammals. Vervets were also the most sensitive in the middle frequency range. Furthermore, we found that de Brazza's monkeys, though they produce a specialized, low-pitched boom call, did not show the enhanced low-frequency sensitivity that Brown and Waser (1984) showed for blue monkeys (C. mitis), a species with a similar sound. This discrepancy may be related to differences in the acoustics of the respective habitats of these animals or in the way their boom calls are used. The acuity of Japanese monkeys was found to closely resemble that of rhesus macaques (M. mulatta) that were tested in previous studies. Finally, humans tested in the same apparatus exhibited normative sensitivities. These subjects responded more readily to low frequencies than did the monkeys but rapidly became less sensitive in the high ranges.     

Toward a reconstruction of medical morality

At the center of medical morality is the healing relationship. It is defined by three phenomena: the fact of illness, the act of profession, and the act of medicine. The first puts the patient in a vulnerable and dependent position; it results in an unequal relationship. The second implies a promise to help. The third involves those actions that will lead to a medically competent healing decision. But it must also be good for the patient in the fullest possible sense. The physician cannot fully heal without giving the patient an understanding of alternatives such that he or she can freely arrive—together with the physician—at a decision in keeping with his or her personal morality and values. In today's pluralistic society, universal agreement on moral issues between physicians and patients is no longer possible. Nevertheless, a reconstruction of professional ethics based on a new appreciation of what makes for a true healing relationship between patient and physician is both possible and necessary.     

临床伦理学的未来方向

1　既往史序言本文是描述临床伦理学领域系列文章中的最后一篇。我们在本文中预测临床伦理学若干可能的方向。我们选定为今后 2 0年作些推测———这是一个大致上相等于美国现代生命医学伦理学运动整个历史的时期。在以往 2 0年中 ,生命医学伦理学是跟生物学与医学的革命性发展同步的。其结果是 ,生命医学伦理学在这个时期比它在整个既往历史中变化得更为深刻。今日 ,生命医学伦理学不仅使伦理学家们高度感兴趣 ,而且使我们社会全体都高度感兴趣 ,包括卫生界、公众、法院、媒体及政策制订者。在一个 2 5 0 0年中甚少变化 ,几乎只把它眼光限…     

Stochastic transitivity and the unidimensional control of choice

A concurrent-chains paradigm was used to test three models of preference for schedules of reinforcement. Each model assumes choice to be a monotonic function of values on a single dimension (“simple scalability”). For choices involving variable-interval and fixed-interval schedules, this dimension is assumed to be an harmonic average of the interreinforcement intervals; for choices involving fixedinterval and fixed-ratio schedules, the dimension is the time to reinforcement irrespective of response rate; for choices involving different combinations of rate and duration of reinforcement, the dimension is the rate of “reinforcement-time”, or the product of the two parameters. Each model implies a strong form of transitivity (“functional equivalence”), which held for half the subjects (that half exclusively sensitive to the reinforcement variable specified by the model). An alternative unidimensional model which implies a weaker form of transitivity (“weak binary utility model”) was consistent with the preferences of all subjects. This model states that a single factor controls the direction of preferences but not necessarily the exact choice probability, as simple scalability assumes.
