Several techniques have been used in applied research as controls for the introduction of a reinforcement contingency, including extinction, noncontingent reinforcement (NCR), and differential reinforcement of other behavior (DRO). Little research, however, has examined the relative strengths and limitations of these "reversal" controls. We compared the effects of extinction with those of NCR and DRO in both multi-element and reversal designs, with respect to (a) rate and amount of response decrement, (b) rate of response recovery following reintroduction of reinforcement, and (c) any positive or negative side effects associated with transitions. Results indicated that extinction generally produced the most consistent and rapid reversal effects, with few observed negative side effects. 相似文献

This paper investigates whether culture can be used to segment a market. Using Indians, resident in Britain (British Indians) as an example, previous research suggests that culture's manifestation within buyer behaviour provides sufficient evidence to justify its use as a market segment variable. Using brown goods (television sets, video equipment, music systems etc) a comparative quantitative study examined the impact of a range of cultural values upon the buying behaviour of British Indians and British Caucasians, to identify significant differences between the two. Although a significant difference was found, the amount of similarity between the two sample groups suggests culture should not be used as a segmentation variable. This research has implications for organisations seeking to develop ethnic minority orientated marketing strategies. Copyright © 2003 Henry Stewart Publications. 相似文献

Presentence reports on 628 offenders were content analyzed. Regression analysis found that remorseful offenders received less severe sentences than non-remorseful offenders. Offenders convicted of minor offenses received more lenient sentences if they had used alcohol in conjunction with their crimes than if they did not use alcohol. The opposite was the case for offenders commiting serious crimes. Remorseful offenders with few prior alcohol-related convictions received less severe sanctioning than non-remorseful offenders with similar conviction records. In contrast, recidivists who were remorseful were dealt with more harshly than their non-remorseful counterparts. 相似文献
