Young disadvantaged workers are especially vulnerable to harassment due to their age and social class position. As young people enter the workforce, their experiences of, and reactions to, harassment may vary dramatically from those of older adult workers. Three case studies introduce theory and research on the relationship between social class and harassment of young workers. We suggest two mechanisms through which class may structure harassment experiences: (1) extremely vulnerable youth are directly targeted based on their social class origins, and (2) the type and condition of youth employment, which is structured by class background, indirectly affect experiences of harassment. 相似文献

The ability to isolate a single sound source among concurrent sources and reverberant energy is necessary for understanding the auditory world. The precedence effect describes a related experimental finding, that when presented with identical sounds from two locations with a short onset asynchrony (on the order of milliseconds), listeners report a single source with a location dominated by the lead sound. Single-cell recordings in multiple animal models have indicated that there are low-level mechanisms that may contribute to the precedence effect, yet psychophysical studies in humans have provided evidence that top-down cognitive processes have a great deal of influence on the perception of simulated echoes. In the present study, event-related potentials evoked by click pairs at and around listeners' echo thresholds indicate that perception of the lead and lag sound as individual sources elicits a negativity between 100 and 250 msec, previously termed the object-related negativity (ORN). Even for physically identical stimuli, the ORN is evident when listeners report hearing, as compared with not hearing, a second sound source. These results define a neural mechanism related to the conscious perception of multiple auditory objects. 相似文献

Research indicates the presence of an age-related pictorial processing deficit, for which the elderly may attempt to compensate
through the use of relational information. Cognitive asynchrony theory, a recent synthetic formulation which unites elements
of the generalized slowing hypothesis, environmental support theory, and the item-specific/relational information distinction,
has proven useful in a number of experiments in explaining these aspects of visual cognitive aging. The present experiments
tested this theoretical formulation under high processing demand conditions in both the relational and the pictorial/item-specific
realm. Young and older adults yielded a complex pattern of results consistent with the cognitive asynchrony synthesis of these
theoretical considerations. The present experiments add to the growing body of findings indicating that the cognitive subsystems
of memory decline at different rates, that the differences in cognitive processing between young and older adults tend to
be more quantitative than qualitative, and that the global age-related memory deficits of popular belief are in fact relatively
circumscribed and specific.

Analysis of naturalistic chewing patterns may provide insight into mapping the neural substrates of jaw movement control systems, including their adaptive modification during the classically conditioned jaw movement (CJM) paradigm. Here, New Zealand White rabbits were administered food and water stimuli orally to evaluate the influence of stimulus consistency on masticatory pattern. Chewing patterns were recorded via video camera and movements were analyzed by computerized image analysis. The mandibular kinematics, specifically the extent of dorsal/ventral, medial/lateral, and rostral/caudal movement, were significantly larger in food-evoked than water-evoked chewing. Water-evoked chewing frequency, however, was significantly higher than that of food-evoked movements. In light of known cortical mastication modulatory centers, our findings implicate different neural substrates for the responses to food and water stimuli in the rabbit. A detailed delineation of jaw movement patterns and circuitry is essential to characterize the neural substrates of CJM. 相似文献

In this study, participants read 3 separate vignettes describing a hypothetical sibling with each of the following disorders: substance abuse, schizophrenia, and a physical illness. As hypothesized, and consistent with attribution theory, the hypothetical patient with a substance-abuse disorder was perceived as having the most control over his or her illness and the associated symptoms, and the patient described as having a physical illness was perceived as having the least control over his or her illness. Also in support of attribution theory, the hypothetical patient described as having a substance-abuse disorder elicited the most negative emotional reactions from participants, and the patient described as having a physical illness elicited the least negative emotional reactions. Again in support of attribution theory and study hypotheses, participants reported the most willingness to help a physically ill hypothetical sibling. 相似文献

The reasons why divided government is on the rise in the United States remain unclear. Of the explanations offered, Fiorina's (1992 ) balancing hypothesis—the idea that voters intentionally cast their ballots in a way that would increase the prospects of split party control—has drawn the most attention. This study gathered empirical evidence to test the hypothesis; its focus was not on whether citizens want divided government, but rather on whether they collectively act in a way consistent with balancing. In September 1900, during the national election campaign, a sample of undergraduates responded to one of five versions of a newspaper article (similar to actual articles about the campaign) that varied with respect to reported polling data on the competitiveness of the congressional and presidential races. The results cast doubt on the merits of the balancing hypothesis. 相似文献

Alfred Adler was largely overlooked during his era because he viewed people as creative beings in control of their own mental health and resisted the then-standard practice of treating human beings from a pedestal with a normative body of laws. His progressive style of treatment has become more popular in an age when efficient and collaborative treatment is valued for the sake of cost-effectiveness. This article positions Adlerian psychotherapy as a form of brief therapy, effective psychotherapy that takes place in 20 sessions or fewer. The article summarizes the fundamentals of Adlerian theory, outlines the general criteria of brief psychotherapy required by managed care companies, and specifically highlights how Adlerian psychotherapy qualifies as brief psychotherapy. 相似文献

This expaloratory study examines the relationship between personality characteristics (extraversion, core self evaluations), social tie characteristics (number, breadth, depth), and three types of expatriate adjustment (general, interaction, and work). Data was collected at two points in time from 75 expatriate employees from one organization on international assignments around the world. Results indicate that core self‐evaluations, but not extraversion, are positively related to the number of ties formed with other expatriates and host country nationals. Social ties with other expatriates were found to provide greater social support, but similar access to information, than those with host country nationals (HCNs). In general, depth and breadth of relationships with other expatriates predicted general and work adjustment; whereas, breadth and total number of relationships with HCNs predicted all three types of adjustment. Overall, these results provide initial support for the importance of social ties in facilitating expatriate adjustment. 相似文献
