The present study investigated the role of the work value of fairness and attributions regarding the causes of absence in supervisor disciplinary decisions. It was hypothesized that supervisors who valued fairness, and those who made internal attributions regarding the cause of a particular absence incident, render more severe disciplinary decisions than supervisors who value fairness less, and who make external attributions. Furthermore, it was hypothesized that the degree to which supervisors valued fairness moderates the relationship between external attributions and the severity of disciplinary decisions. Using a policy capturing approach, results were consistent with predictions. Implications of the results for research and practice are discussed.  相似文献

In the present study, a naturalistic functional analysis procedure was used to assess the effect of environmental stimulation on the stereotypic behavior (body rocking) of an adult whose stereotypy appeared to be induced by an acquired brain injury. Environmental stimulation, operationalized in terms of both physical and social characteristics, resulted in only minimal changes in the occurrence of body rocking. Body rocking occurred in excess of 50% of the observations in all environmental stimulation conditions and in a naturally occurring baseline condition. To our knowledge, this is the first published report of a functional analysis of stereotypy associated with acquired brain injury.  相似文献

As part of this special issue on psychology in primary care settings, we describe the Department of Veterans Affairs' (VA's) new approach to education for practice in the primary care setting and we concurrently address some general issues related to the education of clinical psychologists for practice in this setting. In this article we argue that the primary care psychologist, in parallel with the generalist in medicine, must have a strong generic background in clinical psychology in order to gain the broad range of clinical skills necessary to function effectively as an in-depth generalist (IDG) who is capable of addressing the variety of psychological issues that emerge in the primary care setting. The IDG model of professional practice, which we believe is best suited for primary care/managed care settings, requires extensive training in generic clinical skills and increased time devoted to its implementation at both the predoctoral and the postdoctoral levels.  相似文献

Seven experiments explored the time course of recognition of brief novel melodies. In a continuous-running-memory task, subjects recognized melodic transpositions following delays up to 2.0 min. The delays were either empty or filled with other melodies. Test items included exact transpositions (T), same-contour lures (SC) with altered pitch intervals, and different-contour lures (DC). DCs differed from Ts in the pattern of ups and downs of pitch. With this design, we assessed subjects’ discrimination of detailed changes in pitch intervals (T/SC discrimination) as well as their discrimination of contour changes (T/DC). We used both artificial and “real” melodies. Artificial melodies differed in conformity to a musical key, being tonal or atonal. After empty delays, T/DC discrimination was superior to T/SC discrimination. Surprisingly, after filled delays, T/SC discrimination was superior to T/DC. When only filled delays were tested, T/SC discrimination did not decline over the longest delays. T/DC performance declined more than did T/SC performance across both empty and filled delays. Tonality was an important factor only for T/SC discrimination after filled delays. T/DC performance was better with rhythmically intact folk melodies than with artificial isochronous melodies. Although T/SC performance improved over filled delays, it did not overtake T/DC performance. These results suggest that (1) contour and pitch-interval information make different contributions to recognition, with contour dominating performance after brief empty delays and pitch intervals dominating after longer filled delays; (2) a coherent tonality facilitates the encoding of pitch-interval patterns of melodies; and (3) the rich melodic—rhythmic contours of real melodies facilitate T/DC discrimination. These results are discussed in terms of automatic and controlled processing of melodic information.  相似文献

The inhibition of return of visual attention based on stimulus color was examined in three experiments. In the first experiment, a discrete trial paradigm showed that subjects were slower to detect a color patch if the color matched that of a patch presented earlier in the same location. Experiment 2 showed that the inhibition only occurs if a neutral, nontarget distractor color is presented between presentation of the initial color cue and the subsequent target patch—explaining the previous failures to detect the phenomenon. Experiment 3 extended the results to a different combination of colors. Taken together, the results have important implications for the processing of stimulus attributes such as spatial location and color, and for the conditions necessary for producing inhibition of return.  相似文献

Aggressivity, inattention, hyperactivity, and impulsivity are cardinal dimensions of externalizing behavior problems of childhood. They are diagnostic and clinical features of childhood disorders, and are thought to be linked to the subsequent development of adult disorders such as substance abuse (SA). Little is known, however, about the convergent and discriminant validity of these four constructs. We used multiple measures to develop indices of aggressivity, inattention, hyperactivity, and impulsivity in a sample of 10- to 12-year-old boys (N=183) with and without a family history of SA. Data were taken from mother reports, child reports, teacher reports, and laboratory tasks. The study aims were (1) to test the convergent and discriminant validity of aggressivity, inattention, hyperactivity, and impulsivity; (2) to examine whether the data were consistent with a model specifying the four constructs as indicators of one superordinate factor; and (3) to differentiate boys with and without a family history of SA in construct scores. The results supported the convergent and discriminant validity of the four constructs. Although discriminable, the constructs covaried strongly and were consistent with a model specifying them as indicators of a single superordinate factor. Boys with a family history of substance abuse scored higher than control boys on aggressivity, inattention, and impulsivity scores, but the groups did not differ on hyperactivity scores. The results are discussed in terms of the role of childhood behavior problems in vulnerability to SA.This work was supported by the National Institute on Drug Abuse grant No. DA 05605.  相似文献

This article compares the approach adopted by two recent sociological accounts of religion in modern Britain (by Bruce and Davie). Attention is drawn in broad terms to the parallels between sociological and religious approaches, and a contrast made specifically between a sociology of religion cast in terms of a narrative of decline and diversity (or an account of the place of religion in the perspective of modernity), and one that pays primary attention to indigenous patterns of meaning. Conclusions are drawn as to the limitations of method and apprehension of the one approach, and the openness and potential for comparison of the other.  相似文献

This study examined the relationships between racial identity attitudes and gender role conflict in a sample of 95 African American men ages 23–80 years old. Participants completed the 1981 Black Racial Identity Attitude Scale by Parham and Helms and the 1986 Gender Role Conflict Scale by O'Neil, Helms, Gable, David, and Wrightsman. Results indicated that racial identity attitudes were differentially related to patterns of gender role conflict when racial identity is externally defined. However, an internally defined racial identity had no relationship to gender role conflict. Results are discussed in terms of the significance of racial identity for understanding African American men's conflict associated with traditional male gender role standards and expectations.  相似文献

Increases in the oscillation frequency of bimanual movements produce a switch from an anti-phase (180° relative phase) to an in-phase (0° relative phase) coordination pattern. This finding is observed when subjects are instructed not to intervene when they feel themselves slipping out of the anti-phase pattern. The question addressed in this study concerned how performance would be affected if subjects were instructed to try to maintain the pattern at all times. This issue was addressed using two separate groups of subjects: one group was given the do not intervene instructions, the other group was told to try to stay with the pattern at all times. Forearm rotations were tested in 15 s trials, paced by an auditory metronome set at 1.0, 1.5, 2.0, 2.5, and 3.0 Hz. Frequency distributions of the point estimates of relative phase were analyzed. The Do not Intervene group replicated previous findings, as indicated by the development of a bimodal histogram of relative phase distributions with increases in oscillation frequency. However, a very different pattern of findings emerged with increases in oscillation frequency for the group told to stay with the anti-phase pattern. Rather than a bimodal distribution being developed, the data maintained 180° as its central tendency — no secondary distribution developed around 0° relative phase. These data suggest that volitional control can over-ride the inherent dynamical tendencies of the motor system.  相似文献
