In the first part I discuss the thesis, advanced by John Broome, that intentions are normatively required by all-things-considered judgments about what one ought to do. I endorse this thesis, but remain sceptical about Broome's programme of grounding the correctness of reasoning in formal relations between contents of mental states. After discussing objections to the thesis, I concentrate in the second part on the relation between rational action and rational intention. I distinguish between content-related and attitude-related reasons for propositional attitudes like believing, wanting, and intending something. The former appeal to features of the content of the propositional attitude they are reasons for, the latter would be reasons for a propositional attitude because of features of the propositional attitude as a whole, for example the feature of its being beneficial to believe or to want that p . I try to show that the common philosophical reaction to attitude-related reasons, namely to claim that they are merely content-related reasons in disguise, is mistaken. In its most extreme form such a reaction would fail to respect the first-person character of reasoning which manifests itself in, among other things, the fact that a Moore-sentence and its analogue for intentions cannot be a conclusion of reasoning. In the third part I argue that there are attitude-related reasons for intentions, and, in showing how they influence practical deliberation, I find that their existence can be rendered compatible with the thesis that it is rational to intend to do what one thinks one ought to do.  相似文献

The manipulation of stimulus significance, by instructions from the experimenter, may be taken as an example of verbal conditioning. Consideration of such a mechanism suggested that personality effects previously found in conditioning studies should be apparent in instructional manipulations of significance in a study of the orienting response (OR) to words. Because of recent changes in dimensioning of the personality structure, some of the items originally used to define Eysenck’s extraversion (E) dimension are now used to assess the new dimension of psychoticism (P), suggesting that at least some of the established effects of E upon conditioning may be associated now with P. Hence the P scale was focused on in this study. Words differing on the evaluative dimension of the semantic differential were presented in three blocks, the first under indifferent instructions, the second under instructions to rate the words for their affective impact, and the third under indifferent instructions again. These blocks correspond to baseline, conditioning, and extinction conditions respectively. Electrodermal activity indicated enhanced conditioning, together with greater carry-over effects in the extinction phase, for low-P compared with high-P subjects. The results indicate the importance of personality effects in studies of stimulus significance and illustrate the value of the verbal conditioning mechanism in this area of the OR field. They also suggest the need to re-examine previously obtained E-effects in conditioning studies in light of changing personality tests.  相似文献

This research was undertaken to demonstrate, with correlational evidence, that presenting the rod-and-frame test (RIT) with either limited (tachistoscopic) or unlimited (Oltman’s, 1968, portable RFT) exposure time does not significantly affect the ranking of subjects. The underlying hypothesis is that the intersubject variability of performance on the portable RFT is due essentially to differences in sensitivity to the optostatic vection that appears automatically and almost immediately. Results of the tachistoscopic test show that the effect of angular size of the stimulus is similar to that described in the literature for unlimited time situations, and that subjects’ ranking is very similar regardless of the exposure time (W = .80). However, although a difference is observed between the means of low and high achievers in both types of RFT, intraindividual intertask homogeneity (correlation coefficient) is not verified in each of these subgroups. From these results, one can distinguish two processes in the RFT: the first, vections, has to do with the subject’s postural orientation and seems to playa great role in organizing interindividual differences. The second process, a more cognitive one, has a less striking effect and has to do with the selection of reference frames in perceptual organization.  相似文献

Developed empowerment theory and replicated previous research on citizen participation and perceived control. Few investigators have designed studies that specifically test empowerment theory. This research further extends a theoretical model of psychological empowerment that includes intrapersonal, interactional, and behavioral components, by studying a large randomly selected urban and suburban community sample and examining race differences. Results suggest that one underlying dimension that combines different measures of perceived control may be interpreted as the intrapersonal component of psychological empowerment, because it distinguishes groups defined by their level of participation in community organizations and activities (behavioral component). The association found between the intrapersonal and behavioral components is consistent with empowerment theory. Interaction effects between race groups and participation suggest that participation may be more strongly associated with the intrapersonal component of psychological empowerment for African Americans than for white individuals. Implications for empowerment theory and intervention design are discussed. The authors express appreciation to Steven Rosenstone who was the Principal Investigator for the Detroit Area Study from which the data for our study is based. We also thank Deborah A. Salem and the anonymous reviewers for their thoughtful comments on earlier drafts of this paper.  相似文献

Analyzed case records to determine the costs and service usage patterns for a group of 25 youth randomly selected from the case load of a regional mental health agency. Study participants had extensive histories of publicly supported psychiatric hospitalizations. An average of 36.2 contacts per youth (905 total contacts) with human services providers were documented. Approximately 2 out of every 5 contacts resulted in out-of-home placements. The estimated cost of providing services to the 25 youth exceeded 3 million dollars. The types and costs of treatment services provided to study participants are discussed.  相似文献
