Conclusion Counterpart theorists need not posit the counterpart relation in addition to the identity relations as an Additional relation relating objects across possible worlds. Identity can be viewed as a relation applicable to individuals within possible worlds, while the counterpart relation replaces identity in translations of ordinary utterances which correlate individuals in different possible worlds and, hence, in all modal utterances. CT is, in other words, a theory of modal discourse — it proposes a way of understanding all modal predications. As such, it is not to be seen as providing a second looser sense of identity across worlds, in addition to the narrow sense. Perhaps Lewis' original formulation encourages this misunderstanding insofar as it (see, especially, P2) denies strict identity across possible worlds. Accordingly, I have suggested a modification of CT whereby syntactic restrictions upon variables eliminates any temptation to posit two parallel relations applicable to entities existing in different possible worlds.As has been argued by Alvin Plantinga, The Nature of Necessity, The Clarendon Press, (Oxford, 1974), Chapter VI. 相似文献

In three experiments, behavior maintained by fixed-interval schedules changed when response-independent reinforcement was delivered concurrently according to fixed- or variable-time schedules. In Experiment I, a pattern of positively accelerated responding during fixed interval was changed to a linear pattern when response-independent reinforcement occurred under a variable-time schedule. Overall response rates (total responses/total time) decreased as the frequency of response-independent reinforcement increased. Experiment II showed that the response-rate changes in the first experiment were controlled by the response-reinforcer relation, but the changes in patterns of responding were similar whether concurrently available reinforcement at varying times was response-dependent or response-independent. In the final experiment, the addition of response-independent reinforcement at fixed times to a fixed-interval schedule resulted in changes in both local and overall response rates and in the occurrence of positively accelerated responding between reinforcements. These results suggest that the temporal distribution of reinforcers determines response patterns and that both the response-reinforcement dependency and the schedule of reinforcement determine overall response rates during concurrently scheduled response-dependent and response-independent reinforcement. 相似文献

When people make errors during continuous tasks they temporarily pause and then slow down. One line of explanation has been that they monitor feedback to detect errors, that they may make incidental responses when errors occur (e.g. they may swear) and that they may pause to analyse their errors. In all these cases they may be assumed to act as single channel information processing systems of limited capacity, and to be unable to recognise any new signal until these processes have been completed.
Analysis of response after errors shows that this cannot be the case. Responses after errors are inaccurate, but are not slow when they require the subject to make the response which he should have made on the previous trial (i.e. to make an error correction response). Subjects thus must recognise new signals as soon as they occur. The present results require a new model of error detection and correction, and a model for response programming and priming. 相似文献

The performance of a pictorial assessment instrument and suggestions for clinical application are described. The stylized family illustrations include the following patterns: normal family, detouring, two-generational enmeshment, three-generational enmeshment, parental child, undermined mother and chaotic family. Ninety-eight individuals, five years or older, in twenty families selected depictions most like their own families. Siblings of patients alone or siblings combined with fathers chose the same pattern type as the family therapists 75 and 64% of the time, respectively. These concordances were significant statistically. Clinical uses include identifying promising therapeutic resources and facilitating transitions to systems and relationship issues. 相似文献

This study was designed to delineate the course of sexual satiation in prairie voles (Microtus ochrogaster). Fourteen male-female pairs were allowed to copulate freely for 24 hr under continuous observation. Copulations occurred predominantly during the first few hours and decreased in frequency thereafter. The mean number of ejaculations per pair was 5.6 (range, 2-9). Two thirds of the ejaculations occurred during the first 3 hr, and over 90% took place within the first 7 hr after the first intromission. No ejaculations were observed during the last 8 hr. These results suggest that male capacity to deliver ejaculations to a female is limited and that direct observations reveal a more limited capacity than observations made with time-lapse videotape. 相似文献

The present article introduces a social-exchange model of organizational attachment incorporating both direct exchange and indirect exchange. Participants were 325 university employees. The present results indicated that perceived organizational support (POS) and perceived external prestige (PEP) both contribute to organizational attachment. Further, the results showed that the extent to which POS and PEP are related to organizational attachment is moderated by occupational proxies of cosmopolitan-local role orientation. POS was more strongly related to the affective commitment and withdrawal cognitions of staff and administrators than to those of faculty. PEP was more strongly related to affective commitment and withdrawal cognitions of university faculty than to those of university staff and administrators. The authors discussed the need to incorporate relational variables such as PEP into other social-exchange frameworks. 相似文献

Construed external image and organizational identification: a test of the moderating influence of need for self-esteem 总被引:1,自引:0,他引:1
According to Social Identity Theory (cf., J. G. March & H. A. Simon, 1958), individuals tend to identify with prestigious or high-status groups. Researchers (J. E. Dutton, J. M. Dukerich, & C. V. Harquail, 1994) have revealed that organizational members also identify with organizations that have attractive public images. To gain a better understanding of the theoretical reasons underlying the relationship between image and identification in organizations, the authors examined this relationship in a healthcare setting. In addition, they investigated need for esteem as a moderator of the relationship between construed external image and organizational identification. Consistent with previous findings, the present results indicated that construed external image is positively related to organizational identification. Perhaps it is more important that the present findings also supported need for esteem as a moderator of the relationship between construed external image and organizational identification. 相似文献
