Organizations sometimes present their members with facades of choice: situations that appear to promise a choice but that, in fact, do not do so. Our study examines how facades of choice, relative to genuine choice, influence justice perceptions and negative and compensatory behavioral reactions. We then consider how the adequacy and timing of explanations for façades of choice affect justice perceptions and negative and compensatory reactions following façades of choice. Results indicate that the impact of explanations is influenced by their adequacy and timing (before or after one actually suffers the broken promise inherent in a façade of choice), suggesting that the experience of an injustice may frame a person's understanding of the explanation given for that injustice.  相似文献

This paper introduces the notion of syntactic feature to provide a unified treatment of earlier model theoretic proofs of both the compactness and interpolation theorems for a variety of two valued logics including sentential logic, first order logic, and a family of modal sentential logic includingM,B,S 4 andS 5. The compactness papers focused on providing a proof of the consequence formulation which exhibited the appropriate finite subset. A unified presentation of these proofs is given by isolating their essential feature and presenting it as an abstract principle about syntactic features. The interpolation papers focused on exhibiting the interpolant. A unified presentation of these proofs is given by isolating their essential feature and presenting it as a second abstract principle about syntactic features. This second principle reduces the problem of exhibiting the interpolant to that of establishing the existence of a family of syntactic features satisfying certain conditions. The existence of such features is established for a variety of logics (including those mentioned above) by purely combinatorial arguments.Presented byMelvin Fitting  相似文献

The present study investigated strategic variation in reliance on phonological mediation in visual word recognition. In Experiment 1, semantically related or unrelated word primes preceded word, pseudohomophone (e.g.,trane), or nonpseudohomophone (e.g.,trank) targets in a lexical decision task. Semantic priming effects were found for words, and response latencies to pseudohomophones were longer in related than in unrelated prime conditions. In Experiment 2, related or unrelated word primes preceded word or pseudohomophone targets. A relatedness effect was found for words, although it was significant at a 600-msec prime-target stimulus onset asynchrony (SOA) and not at a 200-msec SOA. There was no relatedness effect for pseudohomophones. Experiment 3 was a replication of Experiment 2, except that pseudohomophones were replaced by nonpseudohomophonic orthographic controls. Facilitation effects for related target words were greater in Experiment 3 than in Experiment 2. The results reflect apparent variations in the expectation that a related prime reliably indicates that a target is a word. Although reliance on phonological mediation might be strategically contingent, there could be a brief time period in which phonologically mediated lexical access occurs automatically. Whether phonological information is maintained or suppressed subsequently depends on its overall usefulness for the task.  相似文献

Transitive inference (TI) effects have been demonstrated in several nonhuman species using a nonverbal version of the task in which A is better than B is represented in a simple simultaneous discrimination, A+B?. Following five-term training (e.g., A+B?, B+C?, C+D?, D+E?), the choice of B over D on test trials is taken as evidence of TI. Recently, differential value transfer from the S+ to the S? in a simultaneous discrimination has been proposed as a noncognitive basis for these effects. Two experiments were conducted to control for differential value transfer. The results suggest that differential value transfer is not the only basis for nonhuman TI performance. An alternative account based on spatial mapping is discussed.  相似文献

This article addresses the increasing involvement of clergy in dangerous situations, particularly family violence. It provides a quick reference guide to assist clergy in assessing for the risk of potential violence with suggested interventions. In a society that is marked by unprecedented levels of violence and a shortage of mental health services, clergy are increasingly being confronted by dangerous situations that require expert crisis intervention skills. This article provides specific, concrete guidelines for clergy confronted by violence in ministry.The Earth is full of violence.Genesis 6:13This article is dedicated to the memory of The Reverend Harold M. Eads of Topeka, Kansas who was stabbed to death in his apartment on December 17, 1978 in East Harlem, New York where he served the poor and disinherited as a United Methodist minister.  相似文献

In a randomized, controlled trial, the authors studied an adjunctive, individual psychotherapy, interpersonal and social rhythm therapy (IPSRT) for bipolar disorder. After stabilizing participants with episode appropriate pharmacotherapy and either IPSRT or intensive clinical management (CM), participants were reassigned to IPSRT or CM in conjunction with pharmacotherapy for 2 years of preventative treatment. Early results (n = 82) suggest that altering participants' treatment assignment at entry to the preventative phase is related to risk of recurrence. Participants remaining in the same treatment for both acute and preventative phases had lower rates of recurrence (< 20% vs. > 40%) and levels of symptomatology over the subsequent 52 weeks than those reassigned to the alternate modality. This finding, consistent with the authors' philosophy that bipolar patients benefit from stable routines, suggests that disruptions in the psychosocial treatment plan contribute to worse outcomes.  相似文献

On 4 consecutive days, respondents were exposed to gratuitously violent or nonviolent intact feature films. They rated the entertainment value of these films. One day after exposure to the last film of the series, respondents participated in ostensibly unrelated research on emotion recognition. As they performed a test, they were neutrally or abusively treated by a research assistant. Thereafter, they were put in a position to harm this assistant. Both provocation and exposure to violent films were found to foster markedly increased hostile behavior. These effects were noninteractive. Moreover, these effects were uniform for respondent gender. Compared to men, women exhibited less hostility overall, however. The findings thus show that prolonged exposure to gratuitously violent films is capable (a) of escalating hostile behavior in provoked men and women, and (b) perhaps more importantly, of instigating such behavior in unprovoked men and women.  相似文献

The Wechsler Preschool and Primary Scale of Intelligence--Revised and the Stanford Binet-Intelligence Scale: Fourth Edition were given to 51 preschool, kindergarten, first, and second grade students. Twelve of 15 Pearson correlations between Wechsler IQs and composite and area scores of the Stanford-Binet IV were statistically significant. It is apparent that the two tests measure similar, but not identical, concepts.  相似文献

Ten students in a personalized university course were given target dates for completing each of 26 lessons. The lessons could be completed before those dates, but not after. The first two failures to complete a lesson by the target date led to "warnings"; the next failure required the student to withdraw from the course. When each student's rate of lesson completion was compared with and without target dates, it was found that students completed an average of 1.0 lesson a day with the target-date contingency and 0.3 without it. Individual data indicated that most students did few or no lessons without the contingency. It was concluded that a target-date contingency is an effective method for maintaining student progress in personalized university courses.  相似文献
