Although role theory has long described how expectations shape role behavior, little empirical research has examined differences among work role requirements and how features of the discrete occupational context may influence the extent to which role expectations are shared among role holders. The authors examined consensus in work role requirements from a sample of over 20,000 incumbents across 98 occupations. They found that consensus systematically decreased as work role requirements ranged from molecular tasks to responsibilities to molar traits. In addition, they found that consensus in these work role requirements was significantly influenced by the amount of interdependence, autonomy, and routinization present in the surrounding task and social contexts. 相似文献
The effects of lexicality on auditory change detection based on auditory sensory memory representations were investigated by presenting oddball sequences of repeatedly presented stimuli, while participants ignored the auditory stimuli. In a cross-linguistic study of Hungarian and German participants, stimulus sequences were composed of words that were language-familiar, lexical, meaningful in Hungarian but language-unfamiliar, not lexical, meaningless in German, and words with the opposite characteristics. The roles of frequently presented stimuli (Standards) and infrequently presented one (Deviants) were fully crossed. Language-familiar and language-unfamiliar Deviants elicited the Mismatch Negativity component of the event-related brain potential. We found differences in processes of change detection depending on whether the Standard was language-familiar, or not. Whereas, the lexicality of the Deviant had no effect on the processes of change detection. Also, language-familiar Standards processed differently than language-unfamiliar ones. We suggest that pre-attentive (default) tuning to meaningful words sets up language-specific preparatory processes that affect change detection in speech sequences. 相似文献
A prescribed physical fitness exercise program was initiated in a small furniture manufacturing plant. The present purpose was to investigate the effect of an intervention to change employees' attitudes and sense of well-being. The objective was to evaluate the changes in employees' attitudes (well-being) attributable to the exercise program. The method of evaluation was the survey administered to a treatment (n = 22) and a mixed (n = 30) control group. A multidimensional attitude survey questionnaire was administered to assess effects over a 6-mo. period. While some changes in job attitudes were observed for the treatment group, those were not the expected changes. Possible explanations for the findings are discussed. 相似文献
The negative effects of false information presented either prior to (proactive interference; PI) or following (retroactive interference; RI) true information was examined with word definitions (Experiment 1) and trivia facts (Experiment 2). Participants were explicitly aware of which information was true and false when shown, and true-false discrimination was evaluated via multiple-choice tests. Negative suggestion, defined as poorer performance on interference items than noninterference (control) items, consistently occurred when the wrong information followed the correct information (RI) but not when it preceded the correct information (PI). These effects did not change as a function of retention interval (immediate, 1 week, or 3 weeks) or number of incorrect alternatives (1 or 3). Implications of this outcome for experiencing incorrect information in both academic and nonacademic situations are considered. 相似文献
In commenting on my critique of the “deviance is dead” thesis (Goode, 2003Goode, Erich. 2003. “The MacGuffin that Refuses to Die: An Investigation into the Condition of the Sociology of Deviance.”. Deviant Behavior, 24: 507–33. [Taylor & Francis Online], [Web of Science ®], [Google Scholar]), Joel Best (in this issue) makes several points which seem shaky. Examined critically–and agreeing that the field has declined during the past 20 years in creativity and influence on sociology generally–the sociology of deviance is far from “dead.” In fact, as indicated by a number of measures, its health is as robust as ever. Here, I grapple with the conundrum of why the “death” myth is so widely accepted among sociologists. It is possible that the field's political incorrectness may provide an explanation to this mystery. 相似文献
Discriminating personally significant from nonsignificant sounds is of high behavioral relevance and appears to be performed effortlessly outside of the focus of attention. Although there is no doubt that we automatically monitor our auditory environment for unexpected, and hence potentially significant, events, the characteristics of detection mechanisms based on individual memory schemata have been far less explored. The experiments in the present study were designed to measure event-related potentials (ERPs) sensitive to the discrimination of personally significant and nonsignificant nonlinguistic sounds. Participants were presented with random sequences of acoustically variable sounds, one of which was associated with personal significance for each of the participants. In Experiment 1, each participant’s own mobile SMS ringtone served as his or her significant sound. In Experiment 2, a nonsignificant sound was instead trained to become personally significant to each participant over a period of one month. ERPs revealed differential processing of personally significant and nonsignificant sounds from about 200 ms after stimulus onset, even when the sounds were task-irrelevant. We propose the existence of a mechanism for the detection of significant sounds that does not rely on the detection of acoustic deviation. From a comparison of the results from our active- and passive-listening conditions, this discriminative process based on individual memory schemata seems to be obligatory, whereas the impact of individual memory schemata on further stages of auditory processing may require top-down guidance. 相似文献
The cognitive representation of blind regions varies considerably between patients with vision loss and may influence compensatory behaviour and treatment motivation. We therefore measured “objective” visual field topography (perimetry) in 19 patients with postgeniculate visual system lesions and related this to the subjective scotoma representation as expressed by patients’ drawings of the defect and monitored changes of these measures during training-induced recovery of function. Blind regions were mostly adequately represented; however, central regions were overestimated and peripheral areas underestimated in size. Perimetric and subjective defect size decreased significantly during training. Again, training-induced visual field border shifts in central regions were larger in subjective than in perimetric maps but vice versa in the peripheral field. Thus, vision restoration therapy improves “objective” visual field size along with its cognitive representation. The subjective topography is shaped by the functional importance of visual field regions and is a function of cortical magnification, thus resembling the neural representation in visual cortex. 相似文献
Despite the crucial nature of needs assessment in training design and development, very little empirical work examining factors that influence such ratings has been undertaken. We investigated the impact of individuals' levels of work experience, self-efficacy, and skill proficiency on their subsequent ratings of training needs. Our results indicate that self-efficacy and skill proficiency are positively related to importance and frequency ratings for both skills and job tasks. However, when considered collectively, skill proficiency was a more potent influence, suggesting that an individual's actual capability may have a greater impact on ratings of training needs than his or her perceived capability (i.e., self-efficacy). Implications for future research and training needs assessment practice are discussed. 相似文献
Across two studies, we directly test the widely held tenet in the scholarship of organizational citizenship behavior (OCB) that individuals choose to engage in OCB as a result of felt obligations to reciprocate. We further examine how obligations to reciprocate operate against a backdrop of relevant contextual factors (accountability) and individual differences (proactive personality and interpersonal skill). Using an experimental method, we find evidence supporting the proposition that reciprocity obligations increase OCB engagement and that these effects are amplified by contexts high in accountability and when individuals possess high levels of proactive personality. In a subsequent field study, we find further corroborating evidence for the effects of reciprocity obligations on OCB and reaffirm the moderating influences of proactive personality and accountability. Overall, the convergent evidence supports the causal relationship between reciprocity obligations and OCB, as well as explicates the conditions under which this foundational effect operates across individuals and varying contexts.
