This study tested questions of ecological validity by comparing the eyewitness testimonies of children directly experiencing a painful inoculation experience those of children in a yoked-control group who vicariously experienced the inoculation onwith videotape. The study involved 86 5-year-olds, divided between 2 groups: the experiential and yoked control. The experiential group was followed through a health department with a video camera as they received diphtheria, pertussis, tetanus (DPT), and oral polio inoculations. They were tested immediately, 20 min later, and 1 month later. Each child in the yoked-control group merely watched the videotape of his or her counterpart in the experiential group, made similar ratings of pain, and was given the same tests and suggestions. Stress and personal experience affected items congruent with the stressor to produce flashbulb-like memories, with slower rates of forgetting for some items, such as nurse identifications, and greater suggestibility for other items, such as estimates of needle size. These and the apparently conflicting results in the literature were said to make sense when personally experienced stress was viewed from S.-A. Christianson's (1992) interactive perspective rather than as a single ubiquitous variable.  相似文献

Category-specific impairments of object recognition and naming are among the most intriguing disorders in neuropsychology, affecting the retrieval of knowledge about either living or nonliving things. They can give us insight into the nature of our representations of objects: Have we evolved different neural systems for recognizing different categories of object? What kinds of knowledge are important for recognizing particular objects? How does visual similarity within a category influence object recognition and representation? What is the nature of our semantic knowledge about different objects? We review the evidence on category-specific impairments, arguing that deficits even for one class of object (e.g., living things) cannot be accounted for in terms of a single information processing disorder across all patients; problems arise at contrasting loci in different patients. The same apparent pattern of impairment can be produced by damage to different loci. According to a new processing framework for object recognition and naming, the hierarchical interactive theory (HIT), we have a hierarchy of highly interactive stored representations. HIT explains the variety of patients in terms of (1) lesions at different levels of processing and (2) different forms of stored knowledge used both for particular tasks and for particular categories of object.  相似文献

Parkinson's disease (PD) patients often show reductions in writing size (micrographia) as the length of the text they produce increases. The cause for these reductions in stroke size are not well understood. Reductions in stroke size could be associated with either concurrent processing demands that result from the coordination and control of fingers, wrist, and arm during writing and the processing of future words or increased extension of the wrist joint as the execution of the writing progresses to the right across the page, resulting in increased stiffness in the pen-limb system. Parkinson's patients and elderly controls wrote phrases of different lengths with target patterns in various serial positions. When the number of words to be written increased, PD patients reduced their stroke size of the initial target pattern, while the elderly controls did not reduce their stroke size. There was no systematic change in stroke size of the second pattern as function of serial position. This result suggests that PD patients reduce the size of their handwriting strokes when concurrent processing load increases.  相似文献

In the West, we have adoped the word calligraphy to describe Chinese and Japanese writing out of the recognition that there is an aesthetic component inherent in the written characters. The author shows how Chinese and Japanese calligraphy is much more than writing; it must be approached as one would any piece of art. A brief history of Chinese and Japanese calligraphy is explored, including the elements and methods of brushwork and overall creation of the expressions themselves. The article concludes by looking at how calligraphy is a mode of self-discovery and self-development that opens us to a substantial dialogue between cultures and the paths of inner conversation.  相似文献

The role of religious fundamentalism and its relationship to shame and guilt was evaluated in 107 students who attend a church-sponsored university. A number of personality measures were given and gender differences were analyzed. The role of externalization was similar for males in this sample to that of earlier studies. However, it was found that females showed positive correlations between externalization and both shame and guilt. For females, more fundamentalistic religious training may help to contribute to an external orientation at the expense of identifying with a personal religion, and appropriate guilt.  相似文献

Exposure to electrical current via industrial or residential accidents or lightning strikes is a serious and growing concern in today's medical community. The sequelae that result are referred to as electrical injury (EI) or lightning injury (LI). The relevant principles in electricity are reviewed with particular attention given to their damaging capabilities on the body. Specific neuropsychological, psychiatric, and neurological signs and symptoms as well as objective measures of psychological and neuropsychological functioning and brain imaging in victims of EI and LI, are reviewed from past research. Important issues relevant to researchers in the field are discussed. Finally, the role that neuropsychology might play in this area is outlined.  相似文献

Binocular rivalry occurs when the two eyes are presented with incompatible stimuli and the perceived image alternates between the two stimuli. The aim of this study was to find out whether the periodic perceptual loss of a monocular stimulus during binocular rivalry is mirrored by a comparable loss of contrast sensitivity. We presented brief test stimuli to one eye while its conditioning stimulus was dominant or suppressed. The test stimuli were varied widely across four stimulus domains--namely, the relative stimulation of medium- and long-wavelength-sensitive cones, duration, spatial frequency, and grating orientation. The result in each case was the same. Suppression depended slightly or not at all on the type of test stimulus, and contrast sensitivity during suppression was around 64% of that during dominance. The effect of suppression on sensitivity is therefore very weak, relative to its effect on the perceived image. Furthermore, suppression was largely independent of the similarity between the conditioning and the test stimuli, indicating that our results are better explained by eye suppression than by stimulus suppression. A model is presented to account for the small, monocular sensitivity loss during suppression: It assumes that test detection precedes conditioning stimulus perception in the visual pathway.  相似文献

Whether lung transplantation improves Health-related Quality of Life in patients with emphysema and other end-stage lung diseases before and after lung transplantation was examined. Between 1992 and 1999, 23 patients with emphysema and 19 patients with other indications completed self-administered questionnaires before lung transplantation, and at 4, 7, 13, and 25 mo. after transplantation. The questionnaire included the Nottingham Health Profile, the State-Trait Anxiety Inventory, the Self-rating Depression Scale, the Index of Well-being, the self-report Karnofsky Index, and four respiratory-specific questions. Neither before nor after transplantation were significant differences found on most dimensions of Health-related Quality of Life between patients with emphysema and other indications. Before transplantation, both groups report major restrictions on the dimensions Energy and Mobility of the Nottingham Health Profile, low experienced well-being, depressive symptoms, and high dyspnea. About 4 mo. after transplantation, most Health-related Quality of Life measures improved significantly in both groups. These improvements were maintained in the following 21 mo.  相似文献

This paper combines three elements: a discussion of democratic values and the status of outsiders in Japanese political culture, the development of new measures to examine sensitive issues of nativism and foreigner perception in Japan, and an empirical exploration of the relationship between democratic values and antipathy toward outsiders. Two forms of democratic orientation were investigated in a sample of about 1,000 university students in Japan: a defensive version, which adheres to the formalistic requirements of democracy but is exclusionary and illiberal, and a universalist version that is liberal and tolerant. A defensive orientation is associated with greater chauvinism, a greater sense of threat emanating from foreigners, and a heightened anxiety about economic competition. A universalist orientation is associated with low perceived threat and low chauvinism, a lack of fear of economic competition, and a positive view of the cultural contributions of outsiders. Nativism may indeed be compatible with democratic values, but only with the defensive, exclusionary form. In short, the defensive form is democracy for xenophobes. Such an orientation is not unique to Japan, but is likely to be found in developing democracies as well as in advanced democracies that feel threatened.  相似文献
