In an era when lies and misrepresentations about historical events easily become firmly rooted, Michael Sells's discussion illustrates the importance of careful historical research as a moral enterprise. In addition to the skills of the historian, however, there is also room in this enterprise for those of the ethicist. In particular, I warn against confusing the truth or falsity of claims about one narrow historical period with larger questions about the moral meaning and significance of those claims. Illustrating this, I argue one cannot assess the legitimacy of competing nationhood claims solely on the basis of the deeds of specific actors. Nor should the actions of a single individual like the Grand Mufti of Jerusalem be converted into a totalizing claim about the rights of the Palestinian people. 相似文献

In mid‐June 2009, the Obama administration dissolved the President's Council on Bioethics (PCBE), a group established by President George W. Bush in August 2001 and whose nearly eight‐year life was marked from beginning to end by controversy. While some will regret the PCBE's passing, others will regard the Council as a failed experiment in doing public bioethics. 相似文献

Sidman and his colleagues derived behavioral tests for stimulus equivalence from the axiom in logic and mathematics that defines a relation of equivalence. The analogy has generated abundant research in which match-to-sample methods have been used almost exclusively to study interesting and complex stimulus control phenomena. It has also stimulated considerable discussion regarding interpretation of the analogy and speculation as to its validity and generality. This article reexamines the Sidman stimulus equivalence analogy in the context of a broader consideration of the mathematical axiom than was included in the original presentation of the analogy and some of the data that have accumulated in the interim. We propose that (a) mathematical and behavioral examples of equivalence relations differ substantially, (b) terminology is being used in ways that can lead to erroneous conclusions about the nature of the stimulus control that develops in stimulus equivalence experiments, and (c) complete analyses of equivalence and other types of stimulus-stimulus relations require more than a simple invocation of the analogy. Implications of our analysis for resolving current issues and prompting new research are discussed. 相似文献

The relationship of cognitive capacity, cognitive egocentrism, and experience factors to decision making in a contraceptive usage problem was examined. Fifty sexually active, unmarried females, ages 14-19, served as subjects. Using correlational, regression, and canonical correlational analyses, cognitive capacity and cognitive egocentrism variables, not experience with contraceptives, were found to be significantly related to, and predictive of, five of seven decision-making variables. Forty-one percent of the variance was accounted for in predicting the canonical decision-making variable. The implications of these results for future research are discussed. 相似文献

The hypothesis that behavioral asymmetries with the dual task paradigm represent manual dominance was investigated with right- and left-handed males performing verbal and spatial tasks ordered by complexity. Lateralization was assessed for nonideational (perfunctory) and ideational (purposeful) components of tasks with multivariate and ANCOVA procedures. The outcomes of prerequisite tests showed the assumptions for conducting ANCOVA procedures were not satisfied with different handedness groups in the same design. However, results of the multivariate analyses suggest lateralized effects are more likely to represent the cognitive task when interference is high and may represent manual dominance when interference is low. 相似文献

In this study we attempted to operationalize, measure, and increase happiness among people with profound disabilities. Happiness indices were defined and observed among 5 individuals. Validation measures indicated that (a) increases in happiness indices were observed when individuals were presented with most preferred stimuli relative to least preferred stimuli, (b) increases in unhappiness indices were observed when they were presented with least preferred relative to most preferred stimuli, and (c) practitioner ratings of participant happiness coincided with observed indices. Subsequently, classroom staff increased happiness indices through presentation and contingent withdrawal of activities. Results suggested that a behavioral approach can enhance happiness as one aspect of quality of life among people with profound disabilities. Research directions are offered that focus on using a behavioral approach to investigate other private events that are important among people with disabilities. 相似文献

Perception of voicing for stop consonants in consonant-vowel syllables can be affected by the duration of the following vowel so that longer vowels lead to more “voiced” responses. On the basis of several experiments, Green, Stevens, and Kuhl (1994) concluded that continuity of fundamental frequency (f0), but not continuity of formant structure, determined the effective length of the following vowel. In an extension of those efforts, we found here that both effects were critically dependent on particular f 0s and formant values. First, discontinuity inf0 does not necessarily preclude the vowel length effect because the effect maintains whenf0 changes from 200 to 100 Hz, and 200-Hz partials extend continuously through test syllables. Second, spectral discontinuity does preclude the vowel length effect when formant changes result in a spectral peak shifting to another harmonic. The results indicate that the effectiveness of stimulus changes for sustaining or diminishing the vowel length effect depends critically on particulars of spectral composition. 相似文献
