A joint impact hypothesis on symptom experience is introduced that specifies the role of negative mood and self-focus, which have been considered independently in previous research. Accordingly, negative affect only promotes symptom experience when people simultaneously focus their attention on the self. One correlational study and 4 experiments supported this prediction: Only negative mood combined with self-focus facilitated the experience (see the self-reports in Studies 1, 2a, & 2b) and the accessibility (lexical decisions, Stroop task in Studies 3 & 4) of physical symptoms, whereas neither positive mood nor negative mood without self-focus did. Furthermore, the joint impact of negative mood and self-focused attention on momentary symptom experience remained significant after controlling for the influence of dispositional symptom reporting and neuroticism. 相似文献

Although adolescents of different countries often draw pictures of the ideal woman cooking or working in an office, the meaning of the images may vary cross-culturally. In the present study, 88 adolescents from the Philippines, the U.S.A., and Guatemala interpreted drawings by their same-nationality peers. Interpreters from all three countries described the woman working in an office as hardworking and the woman cooking as a mother cooking for her family. In addition, Filipino adolescents wrote themes of contentment and organization, Guatemalan adolescents wrote themes of betterment, family, and hope, and U.S.A. adolescents wrote themes of contentment and niceness. Similar images of women's roles may have different meanings for adolescents of different cultures, and the use of emic approaches can provide psychological researchers with increased understanding of complex social phenomena. 相似文献

We look at the problem of revising fuzzy belief bases, i.e., belief base revision in which both formulas in the base as well as revision-input formulas can come attached with varying degrees. Working within a very general framework for fuzzy logic which is able to capture certain types of uncertainty calculi as well as truth-functional fuzzy logics, we show how the idea of rational change from “crisp” base revision, as embodied by the idea of partial meet (base) revision, can be faithfully extended to revising fuzzy belief bases. We present and axiomatise an operation of partial meet fuzzy base revision and illustrate how the operation works in several important special instances of the framework. We also axiomatise the related operation of partial meet fuzzy base contraction.This paper is an extended version of a paper presented at the Nineteenth Conference on Uncertainty in Arti.cial Intelligence (UAI’03). 相似文献

The somewhat crude question of whether we need neuropsychotherapy means more precisely whether its neuroscientific perspective can be useful for the psychotherapeutic practice. To answer this question the traditional scientific approaches do not completely suffice. The ??empirical-technical approach?? of quantitative psychotherapy research is of no service here as neuropsychotherapy is only its continuation. Within the framework of this methodology it is not possible to critically reflect on the relevance of neuroscientific research. Such a reflection is, however, the prerequisite for an evaluation of the benefits of neuropsychotherapy. The question about the meaning of neurobiological processes thus leads to the field of epistemology. This ??theoretical approach?? is nonetheless only helpful within limits. It provides an important background of reflection, however it needs to remain abstract compared to psychotherapeutic practice because it does not integrate the specific goals of such practice. What is presented here instead is an ??approach of pragmatic reflection??. This reflection departs from a general purpose of psychotherapy from which the value of neuropsychotherapy can be appropriately estimated. After this clarification the approach of pragmatic reflection can be preliminarily demonstrated with concrete applications of neuroscience in psychotherapy. What is shown hereby is that neuropsychotherapy represents a very specific practice of argumention and action, which implements a logic into psychotherapy that does not fit its contents and goals. 相似文献

CPEB is a sequence-specific RNA binding protein that regulates translation at synapses. In neurons of CPEB knockout mice, synaptic efficacy is reduced. Here, we have performed a battery of behavioral tests and find that relative to wild-type animals, CPEB knockout mice, although similar on many baseline behaviors, have reduced extinction of memories on two hippocampal-dependent tasks. A corresponding microarray analysis reveals that about 0.14% of hippocampal genes have an altered expression in the CPEB knockout mouse. These data suggest that CPEB-dependent local protein synthesis may be an important cellular mechanism underlying extinction of hippocampal-dependent memories. 相似文献

Two experiments found that effort-related cardiovascular reactivity under ego-involvement follows the principles of motivational intensity theory. Experiment 1 manipulated ego-involvement and the difficulty of a memory task. Under high ego-involvement, cardiovascular reactivity during task performance increased with fixed task difficulty; an unfixed performance standard elicited the same high reactivity as a fixed high standard. Experiment 2 manipulated ego-involvement and administered a memory task with unfixed versus extremely high performance standards. High ego-involvement increased cardiovascular reactivity only when the performance standard was unfixed but not when success was obviously impossible. Both studies found associations between cardiovascular reactivity and achievement and controlled for emotional states. The findings clarify previous research and theorizing about ego-involvement and motivation. 相似文献

Similarities have been observed in the localization of the final position of moving visual and moving auditory stimuli: Perceived endpoints that are judged to be farther in the direction of motion in both modalities likely reflect extrapolation of the trajectory, mediated by predictive mechanisms at higher cognitive levels. However, actual comparisons of the magnitudes of displacement between visual tasks and auditory tasks using the same experimental setup are rare. As such, the purpose of the present free-field study was to investigate the influences of the spatial location of motion offset, stimulus velocity, and motion direction on the localization of the final positions of moving auditory stimuli (Experiment 1 and 2) and moving visual stimuli (Experiment 3). To assess whether auditory performance is affected by dynamically changing binaural cues that are used for the localization of moving auditory stimuli (interaural time differences for low-frequency sounds and interaural intensity differences for high-frequency sounds), two distinct noise bands were employed in Experiments 1 and 2. In all three experiments, less precise encoding of spatial coordinates in paralateral space resulted in larger forward displacements, but this effect was drowned out by the underestimation of target eccentricity in the extreme periphery. Furthermore, our results revealed clear differences between visual and auditory tasks. Displacements in the visual task were dependent on velocity and the spatial location of the final position, but an additional influence of motion direction was observed in the auditory tasks. Together, these findings indicate that the modality-specific processing of motion parameters affects the extrapolation of the trajectory. 相似文献
