E kehammar B. A comparative study of some multidimensional vector models for subjective similarity. Scand. J. Psychol ., 1972, 1 3 , 190–197.—h this report, two theoretical vector models for subjective similarity were deduced from a "content" definition of subjective similarity. One of the derived similarity equations proved in empirical model testing to describe the similarity principle in perception of form better than earlier, similar models. Deviations between observed similarity estimates and values expected according to the model are discussed, among other things, in terms of the heterogeneity of the stimulus set. 相似文献

Kripke-style models with two accessibility relations, one intuitionistic and the other modal, are given for analogues of the
modal systemK based on Heyting's prepositional logic. It is shown that these two relations can combine with each other in various ways.
Soundness and completeness are proved for systems with only the necessity operator, or only the possibility operator, or both.
Embeddings in modal systems with several modal operators, based on classical propositional logic, are also considered. This
paper lays the ground for an investigation of intuitionistic analogues of systems stronger thanK. A brief survey is given of the existing literature on intuitionistic modal logic. 相似文献

Different forms of memory defects were studied in 16 patients with organic dementia. The test performance was related to the regional cerebral blood flow (rCBF) in the left (dominant) hemisphere. Verbal memory (Paired Associates) correlated to the blood flow in temporal and parietal regions. Spatial recognition (Memory for Objects, Memory for Geometrical Design) correlated to the temporal and lower frontal regions. One spatial memory test (Visual Retention test) correlated to the temporal region only. Another spatial memory test (Memory for Design) did not show correlations to any regions of the dominant hemisphere. Finally it was found that the hemisphere mean flow values did not correlate to performance. This emphasizes the main finding—the regional correlations. It is concluded that memory performance involves various extratemporal regions depending upon the specific quality of the memory task to be performed. 相似文献

The induced effect is an apparent slant of a frontal plane surface around a vertical axis, resulting from vertical magnification of the image in one eye. It is potentially important in suggesting a role for vertical disparity in stereoscopic vision, as proposed by Helmholtz. The paper first discusses previous theories of the induced effect and their implications. A theory is then developed attributing the effect to the process by which the stereoscopic response to horizontal disparity is scaled for viewing distance and eccentricity. The theory is based on a mathematical analysis of vertical disparity gradients produced by surfaces at various distances and eccentricities relative to the observer. Vertical disparity is shown to be an approximately linear function of eccentricity, with a slope or gradient which decreases with observation distance. The effect of vertical magnification on such gradients is analyzed and shown to be consistent with a change in the eccentricity factor, but not the distance factor, required to scale horizontal disparity. The induced effect is shown to be an appropriate stereoscopic response to a zero horizontal disparity surface at the eccentricity indicated. However, since extraretinal convergence signals provide conflicting evidence about eccentricity, they may attenuate the induced effect from its mathematically predicted value. The discomfort associated with the induced effect is attributed to this conflict. 相似文献

In a study by Pollak and Gilligan (1982) where fantasies of violence were seen as indicative of perception of danger, women responded with more violent imagery to situations of achievement, whereas men responded with more violent imagery to affiliation situations. This indicates gender differences in motivational needs, which corresponds to modern gender development theories (e.g., Chodorow, 1978). In the present studies, the hypotheses that women fear achievement situations whereas men fear situations of affiliation were tested on Swedish samples totaling 44 men and 47 women. In Study 1, the hypothesis that violent imagery correlates with affiliation themes in the stories written by men was partly supported, whereas the hypothesis that violent imagery would be highly correlated with achievement themes in the stories written by women was not confirmed. In Study 2, no support was obtained for the hypotheses. In sum, contrary to previous studies, no substantial support was obtained for the hypothesis that women connect violent imagery with achievement situations, whereas some evidence was found for the hypothesis that men construe danger as arising from affiliation situations. The greater incidence of violence in men’s fantasy reported in previous studies was not supported in either of the two studies. The results are discussed in the context of cross-cultural differences. 相似文献

Two sentences were constructed having roughly the same content but different predictability ( P -) scores. One or other of the sentences was presented auditorily once only to different groups of subjects who were instructed to listen carefully, without however, being informed of the learning character of the experiment. The groups were then tested for retention after one of the following intervals: IM, 3 min., 2 hours, 20 hours. The sentences were found to differ in memorability (amount recalled) in IM but not in LTM. The reproductions were also analysed with regard to synonym and non-synonym substitutions and the implications for the chunking hypothesis discussed. 相似文献

通过2个研究探索了自恋与暴力犯攻击行为的关系及机制。研究1通过问卷法(N = 498)发现, 自恋与攻击存在正相关, 特质愤怒在自恋与预谋性和冲动性攻击间的中介作用成立, 心理特权的中介作用只对预谋性攻击成立。研究2对90名暴力犯进行了行为学实验, 结果表明威胁感和负性情绪在自恋与攻击间起中介作用, 挑衅调节了上述中介作用。显性自恋者只在挑衅条件下表现出更强的攻击性, 隐性自恋者则在挑衅和无挑衅条件下均有较强的攻击性。研究厘清了不同亚型下自恋与攻击的关系, 突出了隐性自恋的“黑暗性”, 并为罪犯矫治管理及犯罪预防提供了参考。 相似文献
