Children differing in locus of control orientation (internals, mediums, and externals' were administered an extended coding task following either a fictional rationale for the study (purpose incentive statement) or no purpose. As predicted, externals' performance under no purpose was significantly poorer and their rated interest in the task was significantly less favorable than those of internals. Also as predicted, these differences were nullified under the purpose incentive condition. The findings extend Lefcourt's (1967) suggestion that cue explication is important for externals to include external children, and support the position (Mischel, 1973; Rotter, 1975) that personality variables are increasingly important as a function of greater situational ambiguity. Implications of these findings for education and child-rearing are discussed. 相似文献

The present paper presents the results of AIDS Knowledge, Attitudes, Beliefs, and Practices (KABP) surveys conducted in two Caribbean countries: St. Vincent and St. Lucia. Despite religious, socioeconomic, and literacy differences between the two countries, their citizens are remarkably similar with respect to AIDS knowledge, attitudes, beliefs, and practices. The major differences between the two countries concern the perception of AIDS risk and the relative position of AIDS as a serious problem facing the country. These differences, however, appear unrelated to AIDS knowledge, sexual practices, or the likelihood of engaging in AIDS-protective behaviors. These findings question the role of perceived risk of AIDS as a determinant of AIDS-protective behaviors, and, more important, they question the utility of increasing perceived risk as a strategy in AIDS prevention programs. 相似文献

This study investigated the relationship between subjective frequency of literal usage (literalness), subjective frequency of figurative usage (familiarity), and mean Kucera and Francis (1967) word frequency for idiom phrases. Kucera and Francis frequency was found to be independent of both familiarity and literalness. Furthermore, it was found that literalness, but not the Kucera and Francis frequency of the words in the phrase, affected reading time for literal uses of idioms. For figurative uses of idioms, familiarity and written frequency interacted. A model of idiom processing consistent with the current results and previous results is proposed. In addition, subjective familiarity and literalness norms are provided for 245 idioms.Portions of the normative study were based upon subjects in Schweigert and Cronk (1992). 相似文献

Aging and temporal discrimination of brief auditory intervals 总被引:1,自引:0,他引:1
Summary In a duration-discrimination experiment, young adults (mean age = 25.1), middle-aged adults (mean age = 45.5), and older adults (mean age = 64.6) were presented with two very brief auditorily marked intervals per trial, and their task was to decide which of the two was longer in duration. An adaptive psychophysical procedure was used to determine difference thresholds in relation to a constant standard interval of 50 ms. It was found that duration-discrimination performance was unaffected by age; all three age groups yielded a difference threshold of approximately 17 ms. It was concluded that the ability to discriminate durations of very brief auditory intervals appears to be based on an underlying timing mechanism that does not slow down with advancing adult age. 相似文献

The goal of this paper is to show that Callahan's reasons for withholding life extending care cannot be made out exclusively in terms of contemporary notions of distributive justice and fair allocation. I argue that by relying on a notion of justice which links the merit of the individual with the fairness of a social pattern of shares, Callahan imputes vice to the elderly as he denies them eligibility for life-prolonging care. Aristotle's doctrine of the mean is a useful tool for character evaluation. One can speak meaningfully of a proper disposition of a person of a certain type (an elderly person) with respect to the good of continued life. I claim that the mean of one's disposition with respect to the good of continued life would be relative to one's age group, and would be determined by that principle by which an elderly person of practical wisdom would determine it. This leads to very different conclusions than those drawn by Callahan. 相似文献

Adults with developmental disabilities who display behavior disorders repressent some of our field's biggest challenges. Those who provide direct support for such individuals are sometimes frightened and often frustrated by the occurrence of these behaviors parrticularly if neither they nor the agencies for whom they work have been successful in alleviating them. Under such circumstances the agency may secure the services of a consultant. At such times the consultant may find it diffcult to obtain information [from which to generate plausible hypothese and design interventionl plans] that is not unduly influenced by the emotions of the moment. This article describes a stop-gap system that can be used under such circumstsances to gather and analyze valuable longitudinal behavioual ecological data. The basic assumptions and strategies of this system are explained and illustrated through three case studies. 相似文献

Social learning theory suggests that parents and peers influence adolescent drinking directly by providing social reinforcement and models for imitation, and indirectly by first influencing various expectations adolescents form about drinking. In this study, longitudinal data were used to investigate several mediators that could account for the relationships between adolescent beer drinking and parent and peer drinking behaviors and attitudes. The results show that peer drinking indirectly influences adolescent drinking by shaping adolescents' norms on drinking, drinking preferences, and expected consequences of drinking related to friends and problem behavior, whereas parental alcohol use and peer attitude toward alcohol largely directly influence adolescent beer drinking. The results suggest that influence is in large part direct or indirect depending on the source of the influence. In addition, different types of mediators may account for different relationships. 相似文献
