Young (7 days old), middle-aged (30 days old), and old (50 days old) Drosophila melanogaster males were used in an inhibitory conditioning of the proboscis-extension response. Two reinforcement schedules were applied, constant vs. partial. Partial reinforcement increased the number of trials needed to reach the learning criterion to the same extent in all age groups. Young flies needed fewer trials to reach the criterion than both middle-aged and old flies, which did not differ from each other. Extinction was delayed in the partial reinforcement groups by the same amount in all age groups. The slowest rate of extinction was observed in the old group and the fastest for the middle-aged flies. The results are discussed in connection with hypotheses that consider extinction an index either of behavioral rigidity or of strength of the initial learning. 相似文献

This study attempted a replication of previous multidimensional scaling (MDS) results concerning the most salient perceptual features of the Rorschach inkblots. A second purpose was the investigation of the relationships between individual S's relative reliance on these salient features, and personality characteristics as assessed by the Jackson Personality Inventory (JPI). The two-dimension solution obtained in previous research, involving inkblot color and twomess of form, was closely replicated. Only very low correlations between Ss' use of these dimensions, and personality characteristics as measured by the JPI, were obtained. The MDS-Rorschach approach may prove useful in delimiting peculiarities of attention and perception in clinical states. The usefulness of the approach in furthering study of personality constructs assessed through traditional Rorschach administration is currently in question. 相似文献

Construct empirical redundancy may be a major problem in organizational research today. In this paper, we explain and empirically illustrate a method for investigating this potential problem. We applied the method to examine the empirical redundancy of job satisfaction (JS) and organizational commitment (OC), two well-established organizational constructs. Analysis based on responses from a sample of 292 employees collected at two occasions showed that: (a) the construct-level correlation between JS and OC was very high (.91) and (b) both JS and OC are similarly related to positive affectivity and negative affectivity. These results suggest that the constructs may be empirically indistinguishable, despite their well-established conceptual distinction. These findings illustrate the problem of empirical redundancy of organizational constructs and provide a basis for a possible movement towards parsimony in the realm of constructs that could open the way to more rapid advances in knowledge in organizational research. 相似文献

The relationships between personality traits and performance are often assumed to be linear. This assumption has been challenged conceptually and empirically, but results to date have been inconclusive. In the current study, we took a theory-driven approach in systematically addressing this issue. Results based on two different samples generally supported our expectations of the curvilinear relationships between personality traits, including Conscientiousness and Emotional Stability, and job performance dimensions, including task performance, organizational citizenship behavior, and counterproductive work behaviors. We also hypothesized and found that job complexity moderated the curvilinear personality–performance relationships such that the inflection points after which the relationships disappear were lower for low-complexity jobs than they were for high-complexity jobs. This finding suggests that high levels of the two personality traits examined are more beneficial for performance in high- than low-complexity jobs. We conclude by discussing the implications of these findings for the use of personality in personnel selection. 相似文献

The aim of this study was to test the hypothesis that conversational perspective-taking is a determinant of unfamiliar ambiguous idiom comprehension. We investigated two types of ambiguous idiom, decomposable and nondecomposable expressions, which differ in the degree to which the literal meanings of the individual words contribute to the overall idiomatic meaning. We designed an experiment to assess the relationship between the acquisition of figurative comprehension and conversational perspective-taking. Our sample of children aged 5-7 years performed three conversational perspective-taking tasks (language acts, shared/unshared information, and conversational maxims). They then listened to decomposable and nondecomposable idiomatic expressions presented in context before performing a multiple-choice task (figurative, literal, and contextual responses). Results indicated that decomposable idiom comprehension was predicted by conversational perspective-taking scores and language skills, whereas nondecomposable idiom comprehension was predicted solely by language skills. We discuss our findings with respect to verbal and pragmatic skills. 相似文献

The purpose of the current study was to examine the psychometric properties of the Portuguese version of the Duke Religion Index (PDUREL) in a community setting. PDUREL was translated and adapted for administration to 383 individuals from a population-based study of low-income community-dwelling adults. The PDUREL intrinsic subscale and total scores demonstrated high internal consistency (alphas ranging from 0.733 for the total scale score to 0.758 for the intrinsic subscale). Correlations among the DUREL subscales were also examined for evidence of discriminant validity. Correlations were ranging from 0.36 to 0.46, indicating significant overlap between the scales without marked redundancy. PDUREL is a reliable and valid scale. The availability of a comprehensive, but brief measure of religiousness can help to study the role of religiousness in health by researchers from countries that speak the Portuguese language. 相似文献
