The paper deals with certain problems connected with the assumption that choice probabilities ps(x, y) depend on the subject s. A set of postulates is given, which implies the existence of sequences of “classification standards”, i.e., sequences {zj} such that whenever we have 0 < ps0(x, zi) < 1 for some s0 and i, then ps(zi+k, x) = ps(x, zi?k) = 1 for all s, and k ≥ 1. Elements of any such sequence {zj} can serve as boundaries between successive categories of classification based on the following rule: Assign x to jth category if you feel it is “to the right” of zj and “to the left” of zj+1. Under the condition stated above this rule is unambiguous, and the resulting classification has the property that every element is assigned to one of the two neighboring categories, regardless who performs the classification.Next, the postulates are enriched so as to imply the existence of “tightest” among such sequences {zj}, hence leading to a classification with largest number of categories. 相似文献

Some requirements concerning deontic logic are formulated and discussed. Stress is laid on the need to distinguish between theories and deductive systems. It is argued that deontic theories need not be closed under the rule of detachment. Two deontic calculi, called DSC1, DSC2, are presented and talked over.This paper was delivered before the Conference on Practical and Philosophical Motivations of Non-Classical Logics, Toru, August 16, 1979. 相似文献
Biased memory of the past is often a starting point for intergroup conflicts. In three correlational studies, we examined the relationship between need for closure (NFC) and historical ethnocentric bias, a tendency to overestimate the role of one’s ethnic group in the multicultural history of the city of residence. In addition, we checked whether this relationship would be mediated by an individual preference for essentialist places. We found that higher NFC was related to increased historical ethnocentric bias. Moreover, this relation was mediated by preference for an essentialist type of a place. Our results may contribute to understanding the role of individual differences and preferred type of place in shaping a biased representation of the past. Furthermore, our research findings point to the importance of raising awareness of the multicultural past among high NFC individuals.

Sleep problems occur frequently in young children, possibly causing detrimental effects on their development. Parental marital difficulties are known to put a burden on children’s sleep and adjustment. However, research concerning the relation between the parental relationship quality and children’s sleep difficulties is rare for preschool-aged children. This study aims to fill in the gap. Initially, caregivers of 94 preschoolers (41 girls and 53 boys, aged 2–6 years) filled in questionnaires providing information on their children’s sleep and anxiety as well as on their own sleep and relationship quality. A path model approach was used to examine two competing theoretical models linking these factors. The conducted path analysis indicated that children’s separation anxiety, β = ?.134, p = .017, as well as their anxiety in general, β = ?.177, p = .024, partially mediated the relation between the parental relationship quality and children’s sleep problems. Parental sleep problems correlated with the relationship quality, r = ?.371, p = .030, but had no significant influence on children’s sleep. The results of our study suggest that children growing up with parents who state a low relationship quality might thus be concerned about the stability of their family system. As a result children’s sleep quality might be compromised due to irritation and feelings of insecurity. The study highlights the importance of the parental relationship as an influence factor in children’s sleep quality. 相似文献
Recent discoveries in the field of prospective memory (PM) show higher accuracy for remembering intentions in which prospective cue and action are strongly associated. In two experiments presented in this paper, participants encoded both high and low association cue–action pairs and were later tested on both prospective and retrospective PM components. Results of both studies show higher PM accuracy for the low association pairs, compared to high association ones, but only for the prospective component (across both Experiments) and only when a high association cue was presented first (Experiment 2). This finding was accompanied by longer study times for the low association pairs and study times were functionally related to later performance (across both Experiments). In the retrospective component, higher accuracy was observed for pairs with high level of association (but only in the first Experiment). Data are discussed in the context of metacognitive processes possibly related to the encoding of an intention as well as cue monitoring in case of PM tasks with high memory load and varying task difficulty. 相似文献
