Gori and Hamburger (2006, Perception 35 853-857) devised a new visual illusion of relative motion elicited by the observer's motion. We propose that the systematic error of direction discrimination found by Lorenceau et al (1993, Vision Research 33 1207 - 1217) can explain this illusion. The neural correlate of such a systematic error with respect to the two types of neurons in the primary visual cortex, namely end-stopped and contour cells, is discussed. 相似文献

The riddle of Siegfried: exploring methods and psychological perspectives in analytical psychology 下载免费PDF全文
Marco Heleno Barreto 《The Journal of analytical psychology》2016,61(1):88-105
Jung's dream of the killing of Siegfried poses a riddle: why did the unconscious choose precisely Siegfried as the hero to be murdered? Jung himself declares that he does not know. This paper attempts to decipher this riddle using three distinct methodological approaches accepted by Jung, two of them in fact grounded in his theories of dream interpretation. Besides presenting some possible answers to the riddle of Siegfried, this interpretative reflection brings to light the discrepancy of the psychological perspectives created by the heterogeneity of methods within analytical psychology. 相似文献

Trying to uncover the roots of human speech and language has been the premier motivation to study the signalling behaviour of nonhuman primates for several decades. Focussing on the question of whether we find evidence for linguistic reference in the production of nonhuman primate vocalizations, I will first discuss how the criteria used to diagnose referential signalling have changed over time, and will then turn to the paradigmatic case of semantic communication in animals, the alarm calls of vervet monkeys, Chlorocebus pygerythrus. A recent in-depth analysis of the original material revealed that, while the alarm calls could be well distinguished, calls of similar structure were also used in within- and between-group aggression. This finding is difficult to reconcile with the idea that calls denote objects in the environment. Furthermore, nonhuman primates show only minimal signs of vocal production learning, one key prerequisite for conventionalized and symbolic communication. In addition, the structure of calls in different populations or closely related species is highly conserved. In conclusion, any continuity between nonhuman primate and human communication appears to be found at the level of the processing of signals. Why and how the ancestors of our own species one day began to talk to each other continues to be an enigma. Future research should focus on changes in the neural structure supporting volitional control over vocalizations, the gene networks associated with vocal production, and the developmental processes involved in the integration of production and perception of vocalizations. 相似文献

Goodman'snew riddle of induction can be characterized by the following questions: What is the difference between ‘grue’ and ‘green’?; Why is the hypothesis that all emeralds are grue not lawlike?; Why is this hypothesis not confirmed by its positive instances?; and, Why is the predicate ‘grue’ not projectible? I argue in favor of epistemological answers to Goodman's questions. The notions of ‘lawlikeness’, ‘confirmation’, and ‘projectibility’ have to be relativized to (actual and counterfactual) epistemic situations that are determined by the available background information. In order to defend this thesis, I discuss an example that is less strange than the grue example. From the general conclusions of this discussion, it follows that ‘grue’ is not projectible in the actual epistemic situation, but it is projectible in certain counterfactual epistemic situations. 相似文献

After Kant's critique of empiricism, subjectivist epistemologies cropped up in 19th-century German philosophy. Schopenhauer argued that the true essence of every object was an irrational and sexual will. This underlying will distorted a subject's knowledge of the world. Schopenhauer's notion of this true essence was analogous to his portrayal of women; they too were natural, irrational, and instinctual. Nietzsche postulated a will-to-power that structured and hence distorted a chaotic world. That structureless "real" world Nietzsche symbolized as the essential "truth of a woman," a truth which for Nietzsche was unknowable to the desirous male philosopher. Freud, while maintaining belief in empirical truth, developed a psychology of mis-knowledge which had much in common with Schopenhauer's epistemology. His theory of transference grew from a need to explain how female patients libidinally distorted the reality of their male analysts. Conversely, Freud's later writings on women are hampered by the author's realization of his own precarious and subjective position as man trying to know woman. These counter-transferential concerns ultimately made the woman's psychological essence an unknowable riddle for Freud. 相似文献

抑郁具有复杂的、非孟德尔式的多基因遗传模式, 但是目前多数抑郁的遗传研究集中于考察单个候选基因, 不能全面揭示遗传因素的作用机制。近年来, 多基因遗传得分研究和基因−基因交互研究分别为抑郁的多基因累加效应和交互效应提供了新的证据。多基因不仅直接影响抑郁, 还通过与环境因素的交互作用影响抑郁的发生发展, 并且这一复杂交互作用存在性别差异。抑郁的内表型研究发现多基因可能通过认知因素、人格、压力荷尔蒙等间接影响个体的抑郁水平。未来研究应更加关注多基因与多种环境因素如何相互作用影响抑郁, 探索多基因遗传机制的性别差异, 考察多基因对抑郁影响随年龄的发展动态变化。 相似文献

Along with the development of selective serotonin reuptake inhibitors there has been a tremendous widening of the definition of depression and an impressive decrease in the placebo-drug difference in controlled studies. In the early 1960s, about one third of depressed patients improved with placebo and two thirds with active compounds. Current controlled studies suggest that the situation has certainly not improved. The Sequenced Treatment Alternatives to Relieve Depression Study found that response rates to new compounds after the failure of the first antidepressant are low. The monoamine hypothesis of depression was formulated in the mid 1960s based on the antidepressant efficacy of the monoamine reuptake inhibitors, monoamine oxidase inhibitors, and the depressogenic effects of reserpine as a monoamine depleter. However, no monoamine-related finding has been found that is diagnostic for depression. A second major hypothesis regarding depression has been the stress cortisol hypothesis. However, blood cortisol levels are not diagnostic of depression. Psychiatric clinicians are convinced that there are patients for whom antidepressants have made the difference between life and death. However, physicians may generalize unjustifiably based on single dramatic cases to a much larger diagnostic group. Perhaps there are many causes of different types of human sadness, and perhaps only some of these involve mechanisms related to monoamines. Thus, perhaps only some kinds of depression are responsive to monoamine affecting antidepressants.. 相似文献
