The present study based on the indirect Clausen-test using NTA and PHA as antigens contributed to therapy control and possibly prognosis assessment rather than to immunological differential diagnosis.  相似文献

Two experiments demonstrated the way in which musicians and nonmusicians process realistic music encountered for the first time. A set of tunes whose members were related to each other by a number of specific musical relationships was constructed. In Experiment 1, subjects gave similarity judgments of all pairs of tunes, which were analyzed by the ADDTREE clustering program. Musicians and nonmusicians gave essentially equivalent results: Tunes with different rhythms were rated as being very dissimilar, whereas tunes identical except for being in a major versus a minor mode were rated as being highly similar. In Experiment 2, subjects learned to identify the tunes, and their errors formed a confusion matrix. The matrix was submitted to a clustering analysis. Results from the two experiments corresponded better for the nonmusicians than for the musicians. Musicians presumably exceed nonmusicians in the ability to categorize music in multiple ways, but even nonmusicians extract considerable information from newly heard music.  相似文献

In their area of expertise experts know more potentially interfering facts than nonexperts do, yet their memory IS superior to that of nonexperts. This has been termed the “paradox of interference.” We proposed that the ability of experts to go beyond the information given allows them to infer the presence of items that might not otherwise be remembered. However, such inferences can also be detrimental to accurate recognition memory in that such inferences might become confused with actual targets. We examined the benefits and costs of expertise in two recognition memory experiments In which experts and nonexperts participated. Experts in Ex-penment 1 were knowledgeable about baseball; those in Experiment 2 were knowledgeable about Ohio geography. Distractors in both studies bore a synonymous, an inferential, or no special relation to the targets. In the last instance, experts had recognition memory superior to that of the nonexperts. When the distractors were related to the targets, however, the non-experts were superior. We proposed that experts' inferential behavior is a contributor to their generally superior memory, but that task demands can convert this asset into a liability.  相似文献

Within the psychoanalytic school there has been substantial and ongoing debate about the efficacy of teleanalysis. However, as a result of the current COVID-19 pandemic and the online work with which the Jungian analytic community has now had to engage, this paper initially focuses on analysts’ actual experiences of working by teleanalysis. These experiences highlight a range of issues like “Zoom fatigue”, “online disinhibition”, dissonance, confidentiality, the frame and working with new patients. Alongside these issues, there were ample experiences by analysts of both productive psychotherapy apace with analytic work involving transference and countertransference phenomena, all indicating that a genuine and good enough analytic process can occur with teleanalysis. An overview of the research and literature both prior to the pandemic and as a result of it, confirms the validity of these experiences so long as analysts are cognizant of the specifics of such an online modality. Conclusions to do with the question, “what have we learned?”, alongside training, ethics and supervision issues are subsequently discussed.  相似文献
