Performance on three different tasks was compared: naming, lexical decision, and reading (with eye fixation times on a target word measured). We examined the word frequency effect for a common set of words for each task and each subject. Naming and reading (particularly gaze duration) yielded similar frequency effects for the target words. The frequency effect found in lexical decision was greater than that found in naming and in eye fixation times. In all tasks, there was a correlation between the frequency effect and average response time. In general, the results suggest that both the naming and the lexical decision tasks yield data about word recognition processes that are consistent with effects found in eye fixations during silent reading.  相似文献

In recent years a number of writers have defended and attacked various features of structural, or neo-realist theories of international politics. Few, however, have quarrelled with one of the most foundational features of neorealist theory: its assumptions about the nature of science and scientific theories. In this essay I assess the views of science underlying much neorealist theory, especially as they are articulated in the work of Kenneth Waltz. I argue not only that neorealist theories rest on assumptions about science and theory that have been questioned by postpositivist philosophers and historians of science, but also that the failure to consider the work of these writers yields theories of international politics that are deficient in several respects: they are weak theories in the sense that they cannot illuminate crucial features of international politics, they presuppose and sustain a narrow view of power and power relations, they reify practices and relations in the international arena and they offer little promise of producing the sort of Copernican Revolution for which Waltz called (or, more modestly, even a minimally satisfactory theory of international politics). In light of these shortcomings, I sketch an alternative approach to the study of international affairs, one that has been termed prototype studies. I contend that such an approach provides scholars with a rigorous way of studying international politics, without being a theoretical science.  相似文献

Eye movements were recorded in order to examine how different sources of information—namely, meaning dominance and strength of biasing context—influence the processing of biased ambiguous words. Gaze durations were longer on ambiguous target words when the preceding context instantiated the subordinate interpretation, even with strongly biasing contexts. Identical results were obtained with a self-paced reading study. Thus, contrary to recent findings (Kellas, Martin, Yehling, Herman, & Vu, 1995), the subordinate interpretation of a biased ambiguous word was not selectively accessed even when the preceding context strongly biased that interpretation. Discrepancies between the present experiments and the Kellas et al. experiment are discussed.  相似文献

Should software be sold “as is”, totally guaranteed, or something else? This paper suggests that “informed consent”, used extensively in medical ethics, is an appropriate way to envision the buyer/developer relationship when software is sold. We review why the technical difficulties preclude delivering perfect software, but allow statistical predictions about reliability. Then we borrow principles refined by medical ethics and apply them to computer professionals.  相似文献

The philosophical literature on the moral status of nonhuman animals, which is bounteous, diverse, and sophisticated, contains a glaring omission. There is little discussion of human responsibilities to companion animals, such as dogs and cats. The assumption seems to be that animals are an undifferentiated mass – that whatever responsibilities one has to any animal are had to all animals. It is significant that we do not think this way about humans. Most of us (all but extreme impartialists) acknowledge the existence of special responsibilities to humans. We believe, for instance, that our children, friends, and compatriots have special claims on our attention, time, energy, and resources. This is not at all incompatible (although it is sometimes thought to be) with the view that we have obligations to strangers. My aim in this essay is to fill the lacuna in the literature. I argue that the act of taking an animal into one's life or home, through purchase, gift, or adoption, generates responsibilities to it, the main one being to provide for its needs, which, in the case of dogs (for example), are many and varied. Since this thesis is shrouded in misconception, I devote part of the essay to clarifying it. I then diagnose its philosophical neglect, which stems from both practical concerns and theoretical commitments. I argue that the practical concerns are groundless and that the theoretical commitments do not have the implications they are thought to have.  相似文献

Women sometimes attain distinction through their relationships with highly successful men. This association may entail some combination of several individual and dyadic processes. Possible processes were explored in the lives of 48 wives and First Ladies associated with 39 U.S. Presidents. Three primary dimensions of the women's performance were used to determine the connection between their eminence and that of the President. Although a reflected-glory effect was apparent in the unreciprocated influence of the President's reputation on his First Lady's reputation, the woman's reputation was independently determined by (a) her performance as the President's political colleague and (b) her success at establishing her own distinct personality. On the other hand, her reputation was not influenced by her expertise in fulfilling more traditional gender role responsibilities. Some biographical antecedents of the women's performance were also identified.The following research assistants made this project possible: Bergen Achtel, Pamela Akins, Jill Allen, Gazelle Babaee, Paige Black, Nancy Bouffard, Pendra Boyd, Steve Castellón, David Clemons, Jennifer Cohen, Suzanne Dahnert, Ann del Forge, Stephanie Fisher, Fernanda Formel, John Gotelli, Janelle Gray, Kim Haralson, Erin Harrington, Miguel Herrera, Danny Herz, Michele Hill, Alexander Hughes, Elizabeth Judy, Jacques Koujoumajian, Anneliese Makely, Bettina Murphy, Monica Murray, Ryan Nguyen, Tereza Pena-Hibberd, Steven Sacks, Dan Samsky, Todd Sasano, Melissa Schneider, Brian Victor, and Henry Wong.

While the observation of non-human animal behavior has been a major means of developing psychological theories, it has been rarely used by marriage and family therapists to devise or explain systemic ideas. Jane Goodall's multigenerational research on the Flo family of wild chimpanzees in Gombe, Tanzania, as presented in her own and other's writing, and especially in Hugo van Lawick's documentary film,People of the Forest, offers a clear example of how systems concepts' application to animal families may have theoretical, pedagogical, and clinical utility.My thanks to my good friend, Violet Richman, who suggested the subject for this paper.  相似文献

This research compared trends from 1981 to 1993 in several mental health professional training programs at the University of Houston Clear Lake, surveying graduates from three professional mental health master's programs—clinical psychology, school psychology, and family therapy—with the goal of identifying trends in the status of their professional credentialing and current employment. Four mental health groups have attained licensure since a 1981 survey, resulting in graduates now seeking professional licenses and perform psychotherapy more exclusively than other mental health activities. Interdisciplinary training has become increasingly important due to the introduction of managed care and other insurance regulating entities.  相似文献
