In a double-shifting context paradigm, subjects gave magnitude estimates of the perceived intensity of qualitatively dissimilar taste substances (saccharin and quinine, sucrose and quinine) or qualitatively similar ones (saccharin and sucrose), with each pair of substances taking on different contextual sets of concentrations in different sessions. The dissimilar pairs produced substantial differential effects of context (e.g., a particular concentration of saccharin or sucrose was judged more intense than a particular quinine in one contextual setting, less intense in another), but the similar pair did not. This result accords with the hypothesis that differential context effects depend on qualitative similarity. Contrary to expectations, however, the magnitude of the context effect did not differ in tasters and nontasters of the bitter substance 6-n-propylthiouracil (PROP), groups previously shown to differ in sensitivity to bitterness in saccharin. Similarity judgments suggest that saccharin and sucrose were qualitatively alike for ail subjects, regardless of sensitivity to PROP. 相似文献

The computer revolution and the problem of global ethics 总被引:7,自引:0,他引:7

The author agrees with James Moor that computer technology, because it is ‘logically malleable’, is bringing about a genuine
social revolution. Moor compares the computer revolution to the ‘industrial revolution’ of the late 18th and the 19th centuries;
but it is argued here that a better comparison is with the ‘printing press revolution’ that occurred two centuries before
that. Just as the major ethical theories of Bentham and Kant were developed in response to the printing press revolution,
so a new ethical theory is likely to emerge from computer ethics in response to the computer revolution. The newly emerging
field of information ethics, therefore, is much more important than even its founders and advocates believe. 相似文献

This study investigated psychological gender differences in the salience of conversational constraints. It was hypothesized that feminine self-orientations would correlate positively with concern for the hearer’s feelings and concern for avoiding negative evaluation by the hearer, and that masculine self-orientations would correlate positively with concern for clarity. Furthermore, we hypothesized that of the various gender-orientation patterns, androgynous individuals (maintaining high masculine as well as high feminine self-identity simultaneously) will have the highest importance ratings of all the constraints added together; i.e., higher than either undifferentiated (low masculine as well as low feminine self-identity simultaneously) or gender-typed individuals (either low masculine-high feminine or high masculine-low feminine). Partkipants consisted of undergraduate students from diverse ethnic backgrounds. After being presented with four conversational situations, participants rated the perceived importance of each constraint in relation to each situation. They then completed the Bem’sSex- Role Inventory to measure their psychological gender orientation. The results were mostly consistent with the hypotheses. Furthermore, the study showed that one’s psychological gender-role orientation is superior to biological sex categories in accounting for the perceived importance of conversational constraints. 相似文献

This paper described investigation and therapy carried out over a one year period with an adult aphasic patient characterized by severe impairment of auditory comprehension. A deblocking technique was used to reintegrate the mechanisms for correlating sound and meaning. The visual mode of presentation of linguistic material was used both to provide a stable representation of speech units and to allow reinforcement of auditory representations. The patient was given tasks of repetition, reading aloud, and sequencing, using progressively more complex material. The behavior of the patient gives support to the viability of the theoretical constructs of linguistics: this can be seen in the differential processing of function words vs. content words, and in the orderly progression of improvement through stages explicable as the recovery of well-defined and hierarchically dependent subcomponents of linguistic organization. 相似文献

In the present paper we give syntactical and semantical characterization of the class of algebras defined by P-compatible identities of modular ortholattices. We also describe the lattice of some subvarieties of the variety MOL Ex defined by so called externally compatible identities of modular ortholattices. 相似文献

This study introduces and reports an initial test of a theoretical model of play in romantic relationships. It was hypothesized that self–esteem and humor orientation would be positively associated with playfulness in romantic relationships. Playfulness in romantic relationships was predicted to be positively associated with the experience of positive emotion. Positive emotion, in turn, was predicted to be associated with relationship satisfaction. A self–report instrument was administered to students and community members via snowball sampling. Path analysis revealed that the data were consistent with the proposed model. 相似文献

The aim of the study was to examine the possible factors that might contribute to consumer acceptance of food innovations. Particular attention was paid to 3 main factors: (a) relationship between socio‐demographic determinants and level of consumer innovation, (b) evaluation of consumer innovation acceptance, particularly toward animal‐derived food products, and (c) consumer preferences for health‐promoting food innovation over time. Studies were conducted using quantitative research methods in 2004 and 2011. An organic method of production, least important in 2004, was top rated in 2011, and ease of preparation dropped to the bottom of the list in 2011, whereas food origin, low fat, and sugar content were ranked in the first group of the considered factors in 2011. Since 2004, consumers have become used to products with various innovations. The new generation of Poles is relatively more open to new food products, due to the wide range of food products available on the free market. Furthermore, the group of well‐educated consumers with a higher level of income has increased in size, and this includes people interested in knowledge of a product's nutritional value and its health impact. Our study extends existing research in the area of understanding consumer expectations toward food innovations. The results not only contribute to the field of consumer behavior but also have practical potential for food market applications, especially for companies operating on or planning to enter the Polish food market, and which could be used for developing communication strategies. 相似文献

Several findings from both human neuroimaging and nonhuman primate studies suggest that the posterior medial orbitofrontal cortex (OFC) may be critical for the motivational control of goal-directed behavior. The present study was conducted to clarify the role of the left and right posterior medial OFC in that function by examining the effects of focal unilateral lesions to this region on the performance on an incentive working memory task. The study covered patients who had undergone surgery for an ACoA aneurysm and normal control subjects (C). The patients were subdivided into three groups: those with resection of the left (LGR+) or right (RGR+) posterior part of the gyrus rectus, and without such a resection (GR−). Participants performed a 2-back working memory task under three motivational conditions (penalty, reward, and no-incentive). The C group performed worse in the penalty condition and better in the reward condition as compared to the no-incentive condition. Similar results were obtained for the GR− group. Performance of the LGR+ group did not depend on incentive manipulations, whereas the RGR+ group performed better in both the penalty and reward conditions than in the no-incentive condition. The results show that the posterior medial OFC is involved in the motivational modulation of working memory performance. Our findings also suggest that the left posterior medial OFC plays a crucial role in this function, whereas the right posterior medial OFC is particularly involved in the processing of the punishing aspect of salient events and it probably mediates in guiding behavior on the basis of negative outcomes of action. 相似文献

Abstract In order to promote innovation, most theorists agree, high levels of participation by all employees in an organization is required. In Eastern Europe nation-wide interventions are underway in some countries to promote participation across all organizations. This article describes one study of this phenomenon. 相似文献
