Realizing that scientific knowledge was not based on a simple disclosure of reality, but was rather invented and developed in accordance with our own conceptions and prejudices, it should no longer be possible to consider matters as if they existed independently of us out there.Taking as examples the notions of memory and information we try to elucidate the relevance this perspective has with respect to neuro- and psychophysiological research. 相似文献

It has often been claimed that short-term memory search is not selective because it takes longer to categorize the test stimulus than to search throughout the whole memory set. Four experiments investigated whether evidence for selective search can be obtained when effectively no time is required to categorize the test stimulus. Even under this favorable condition, no evidence was found for selective search of only the relevant memory subset. Therefore, the time to categorize a test stimulus cannot be the only reason why short-term memory search is not selective. 相似文献

Surveys confirm risk factors for the incarceration of patients with psychosis including homelessness and comorbidity. There is also agreement that severe psychosis can lead to violence. Data describing prisoners with psychosis in Germany are scarce. We aimed to compare patients with psychosis in a prison hospital and patients with psychosis in a community hospital. Demographic data were collected, as well as comorbidity in the form of substance dependence and a psychiatric assessment using the German version of the 18-item Brief Psychiatric Rating Scale (BPRS) and the Positive and Negative Syndrome Scale (PANSS). In the prison hospital group more patients were homeless (17 versus 2%) and non-German (36 versus 4%). There were also more patients with substance dependence or abuse in the prison hospital group. The total scores of BPRS and PANSS were lower in the prison hospital group (BPRS, 43.8 versus 51.2; PANSS, 71.5 versus 83.7). We assume that social disintegration for mentally disturbed offenders prior to incarceration hindered effective treatment. To avoid further social disintegration and possible further deterioration of mental health status of released offenders, which may lead to reoffending after imprisonment, discharge management after release from prison should be improved. 相似文献

With computer simulations, we examined the performance of the Spearman-Kärber method for analyzing psychometric functions and compared this method with the standard technique of probit analysis. The Spearman-Kärber method was found to be superior in most cases. It generally yielded less biased and less variable estimates of the location and dispersion of a psychometric function, and it provided more power to detect differences in these parameters across experimental conditions. Moreover, the Spearman-Kärber method provided information about the skewness and higher moments of psychometric functions that is beyond the scope of probit analysis. These advantages of the Spearman-Kärber method suggest that it should often be used in preference to probit analysis for the analysis of observed psychometric functions. 相似文献

The development of modern programmable pacemaker-systems has led to a series of questions which until now have apparently not existed in the treatment of cardiac rhythm disturbances. These questions touch especially on the problem of whether the relation which usually exists between a diagnostic step and its therapeutic consequence, namely its therapeutic relevance, is abolished or at least changed. 相似文献
