Age-related declines in understanding conversation may be largely a consequence of perceptual rather than cognitive declines. B. A. Schneider, M. Daneman, D. R. Murphy, and S. Kwong-See (2000) showed that age-related declines in comprehending single-talker discourse could be eliminated when adjustments were made to compensate for the poorer hearing of older adults. The authors used B. A. Schneider et al.'s methodology to investigate age-related differences in comprehending 2-person conversations. Compensating for hearing difficulties did not eliminate age-related differences when the 2 talkers were spatially separated by 9 degrees or 45 degrees azimuth, but it did when the talkers' contributions came from one central location. These findings suggest that dialogue poses more of a problem for older than for younger adults, not because of the additional cognitive requirements of having to follow 2 talkers rather than 1, but because older adults are not as good as younger adults at making use of the auditory cues that are available for helping listeners perceptually segregate the contributions of 2 spatially separated talkers. 相似文献

We hypothesized that representations of social interactions in REM and non-REM (NREM) dreams would reflect differing regional brain activation patterns associated with the two sleep states, and that levels of aggressive interactions would be higher in REM than in NREM dreams. One hundred REM, 100 NREM, and 100 wake reports were collected in the home from 8 men and 7 women using the Nightcap sleep-wake mentation-monitoring system and scored for number and variety of social interactions. We found that (a) social interactions were more likely to be depicted in dream than in wake reports, (b) aggressive social interactions were more characteristic of REM than NREM or wake reports, and (c) dreamer-initiated friendliness was more characteristic of NREM than REM reports. We conclude that processing of, or simulations about, selected social interactions is preferentially performed while "off-line" during the dream state, with the REM state specializing in simulation of aggressive interactions and the NREM state specializing in simulation of friendly interactions. 相似文献

Two studies are reported in which monolingual and bilingual children, approximately 6 years old, attempted to identify the alternative image in a reversible figure. In both studies, bilingual children were more successful than monolinguals in seeing the other meaning in the images. In the first study, there was no relation between the ability to reverse the interpretation and performance on the children's embedded figures task, a task that superficially appeared to involve similar processes. The second study replicated this finding but showed that performance was strongly related to success in the post-switch phase of the dimensional change card sort task. In both cases, the meaning of an image must be reassigned, and bilinguals were better in both these tasks. 相似文献

The influence of intensity range in auditory identification and intensity discrimination experiments is well documented and is usually attributed to nonsensory factors. Recent studies, however, have suggested that the stimulus range effect might be sensory in origin. To test this notion, in one set of experiments, we had listeners identify the individual tones in a set. One baseline condition consisted of identifying four 1-kHz, low-intensity tones; the other consisted of identifying four 1-kHz, high-intensity tones. In the experimental conditions, these baseline tone sets were augmented by adding a fifth tone at either 1 or 5 kHz. Added 5-kHz tones had little effect on identification accuracy for the four baseline tones. When an added 1-kHz tone differed substantially in intensity from the four baseline tones, it adversely affected performance, with the addition of a high-intensity tone to a set of low-intensity tones having a more deleterious effect than the addition of a low-intensity tone to a set of high-intensity tones. These and further results, obtained in an exploration of this asymmetrical range effect in a third identification experiment and in two intensity-discrimination experiments, were consistent with the notion of a nonlinear amplifier under top-down control whose functions include protection against sensory overload from loud sounds. The identification data were well described by a signal-detection model using equal-variance Laplace distributions instead of the usual Gaussian distributions. 相似文献

African Americans have made consistent progress toward first-class citizenship since 1965. Nonetheless, mental health services for this population have been biased, incomplete, and deficient because similarities to European Americans have been emphasized whereas differences were largely ignored. This article addresses some differences, including cultural/racial identity and the cultural self, that affect assessment, psychiatric diagnoses, and psychotherapy or other interventions. An assessment-intervention model illustrates how cultural information can inform service delivery and improve services to African Americans. Cultural/racial perspectives on mental health in a multicultural society suggest innovations in the design of these services and access to them that can increase utilization by African Americans. 相似文献

This article explores self‐reflection and self‐awareness from an ethical standpoint, proposing that counselors have a responsibility to themselves, their clients, and the profession to engage in these practices. The authors propose a path to counselor self‐awareness and a 2nd process that assumes counselor mastery. 相似文献

Scholars have long been concerned that mass media depictions of those with mental disorders foster stigma. Research is needed extricating how particular disorders are represented and perceived, such as obsessive-compulsive disorder (OCD). This article examines what images of obsessions and compulsions exist in the media, and how persons interpret these. It employs two methods: qualitative in-depth interviews and content analysis. Data indicate the media represents obsessions and compulsions in distinguishable ways that both reinforce and complicate common media stereotypes of those with mental disorders—fostering a stigma hierarchy and having contradictory effects on mental health literacy. 相似文献

This article proposes the implementation of the occupational therapy Kawa (Japanese for river) model to promote “culturally relevant” client-centered care for combat and operational stress control services provided in the military context. Currently, the occupational therapy literature lacks a culturally sensitive approach to address the military service members’ experiences with combat and operational stress. A review of the Kawa model features are provided within a case study for a military service member affected by combat and operational stress. This theoretical article offers a pragmatic method for infusing occupational therapy theory to address the cultural aspects of military service members in recovery. 相似文献
