We prove that Brouwer-Zadeh logic has the finite model property and therefore is decidable. Moreover, we present a bimodal system (BKB) which turns out to be characterized by the class of all Brouwer-Zadeh frames. Finally, we show that BrouwerZadeh logic can be translated into BKB. 相似文献

In the present experiments, we attempted to evaluate the modification of the strength of the Poggendorff illusion as a function of the different orientation of a parallel-line texture filling the space between the vertical lines. In Experiment 1, the standard version of the Poggendorff configuration was tested against four different parallel-line textures oriented at 0°, 45°,90°, and 135° with respect to the obliques. The results showed that the illusory effect was a linear function of the progressive discrepancy between the angle of the lines of the texture and that of the obliques. In Experiment 2, we tested the same textures used in Experiment 1 after the elimination of the two vertical lines. The data obtained approximated a linear function, as in the previous experiment, but the alignment errors were consistently lower. The statistical analysis performed on the data of all eight experimental conditions shows that both factors—texture and presence/absence of verticals—were significant, but most of the effect was due to the texture factor. The results may be interpreted through the “perceptual compromise hypothesis,” originally proposed for the bisection forms of the Poggendorff illusion, but with important modifications. The data are also discussed in terms of their implications for other theories proposed for the Poggendorff illusion. 相似文献

An important problem in inductive probability theory is the design of exchangeable analogical methods, i.e., of exchangeable inductive methods that take into account certain considerations of analogy by similarity for predictive inferences. Here a precise reformulation of the problem of predictive analogy is given and a new family of exchangeable analogical methods is introduced.Firstly, it is proved that the exchangeable analogical method introduced by Skyrms (1993) does not satisfy the best known general principles of predictive analogy. Secondly, Skyrms's approach — consisting of the usage of particular hyper-Carnapian methods, i.e., mixtures of Carnapian inductive methods — is adopted in the design of a new family of exchangeable analogical methods. Lastly, it is proved that such methods satisfy an interesting general principle of predictive analogy. 相似文献

We examined the mechanisms that mediate the transfer of information from visual input to storage in memory. Observers performed two concurrent tasks, one of which required input into memory. We discovered that the processes involved in the transfer of information from sensory input into memory cause slowing in concurrent cognitive tasks (dual-task slowing). We used the dual-task slowing effect to demonstrate that memory encoding requires more time when more information is to be encoded and to show that dual-task slowing occurs long after the initial perceptual encoding of visual information (Exp. 1). These results suggest a late and central locus of interaction between the two tasks. Experiment 2 also used two concurrent tasks. However, we reversed the direction of interaction between them and produced a memory deficit from the execution of a concurrent task. Together the results suggest that the mechanisms that encode information into memory belong to a family of mechanisms that are involved in dual-task slowing phenomena and that have been studied under the rubric of the PRP effect (psychological refractory period). We were able to locate the most probable locus of the dual-task interactions to a process that appears necessary for memory encoding. We call this process short-term consolidation.

In this research, we have analysed the role played by the scope of justice and belief in a just world (BJW) in discrimination against immigrants. In Study 1 (n = 185), we found that the relationship between prejudice and discrimination is mediated by a restricted view of the scope of justice. In addition, the results also showed that this mediation is moderated by BJW insofar as the mediation occurred in participants with a high level of BJW but not in participants with a low level of BJW. Studies 2 and 3 experimentally tested our prediction that the legitimising role played by the scope of justice is guided by a justice motive such as BJW. In both studies, the results showed a greater degree of discrimination against immigrants when a restricted scope of justice was considered but only when the BJW was made salient. In sum, these results introduced an innovation into the literature on the legitimation of social inequalities by demonstrating the relevant role played by the justice perceptions in discrimination against immigrants.

Although counselors in 44 states are mandatory reporters of child maltreatment, they may lack an understanding of their legally designated role. This article presents the results of a systematic review of child maltreatment reporting laws in all 50 states and the District of Columbia. The authors apply relevant legislation to real‐life contexts for counselors. 相似文献
