Logics in which a relation R is semantically incomplete in a particular universe E, i.e. the union of the extension of R with its anti-extension does not exhaust the whole universe E, have been studied quite extensively in the last years. (Cf. van Benthem (1985), Blamey (1986), and Langholm (1988), for partial predicate logic; Muskens (1996), for the applications of partial predicates to formal semantics, and Doherty (1996) for applications to modal logic.) This is not so with semantically incomplete generalized quantifiers which constitute the subject of the present paper. The only systematic study of these quantifiers from a purely logical point of view, is, to the best of my knowledge, that by van Eijck (1995). We shall take here a different approach than that of van Eijck and mention some of the abstract properties of the resulting logic. Finally we shall prove that the two approaches are interdefinable. 相似文献

The organization of information when it is retrieved from situation models was explored using recognition and recall tests. A fan effect paradigm was used to assess organization in recognition and a clustering measure was used in recall. People memorized either object-location facts (e.g., “The pay phone is in the city hall”) or person/small location facts (e.g., “The banker is on the witness stand”). For object-location facts, a location-based organization was observed in both recall and recognition. However, for person/small location facts, a location-based organization was observed for recall, and a person-based organization was observed for recognition. Thus, the observed organization was flexible depending on the retrieval task. 相似文献

In this study we compared the ability of narcissism and self-esteem to predict positive illusions in self-evaluations of intelligence and physical attractiveness in a sample of 146 college students. Narcissism predicted both types of illusion for males and females; self-esteem predicted intelligence self-illusion for males. Both males and females overestimated their own intelligence, with males, but not females, also overestimating their attractiveness. Positive illusions for intelligence and attractiveness were correlated. Males showed greater positive illusions than females, with this effect at least partly attributable to observed gender differences in narcissism. 相似文献

Subjects classified as more or less xenophobic allocated resources to SWISS nationals (ingroup) and foreign residents (outgroup) in three intergroup judgement modes: negative interdependence, independence and positive interdependence. When both groups were assessed together as a single beneficiary (positive interdependence) they were allocated more resources than those provided to the outgroup under negative interdependence or independence. More xenophobic subjects, however gave less resources to both groups together under positive interdependence than to the ingroup under independence. In contrast, less xenophobic subjects allocated to both groups together a similar amount as to the ingroup under independence. These results suggest that, depending on their initial attitudes towards the outgroup, individuals will categorize a superordinate entity either more as an ingroup or more as an outgroup. 相似文献

A previous experiment (Doise, Mugny and Perret-Clermont, 1975) has shown that pairs of subjects perform better on a spatial representation task than subjects alone. As a conclusion the hypothesis was put forward that conflicts of cognitive centrations, embedded in a social situation, lead children to coordinate their centrations. The present research was planned to verify several predictions following from this general hypothesis. Results show that indeed more progress takes place when children with different cognitive strategies work together than when children with the same strategies do so, and that not only the less advanced but also the more advanced child progresses when they interact with each other. 相似文献

The COVID-19 pandemic produced multiple stressors that risk relationship conflict and dissatisfaction. We extended prior studies that yielded inconsistent effects of the pandemic on relationships by using propensity score matching to (1) compare levels of relationship conflict and satisfaction during the pandemic (pandemic group; N = 7268) to similar people immediately before the pandemic (matched control group; N = 7268), and (2) compare pandemic groups facing different types of restrictions, beginning with lockdowns involving household isolation to returning to normal life. Results reveal that relationship conflict increased and relationship satisfaction decreased in response to the pandemic, but these effects were very small and primarily occurred in the initial stages of the pandemic when lockdown involved household isolation. The results add to evidence of resilience in personal and relationship well-being in 2020, but also indicate the importance of understanding the effects of varying pandemic-related conditions across the years of the pandemic. 相似文献

The authors present the first part of a study on children with BHS (Breath Holding Spells) syndrome. These children were chosen in order to examine a “pathological” situation in infancy that was as close as possible to a “normal” one, and in which obvious somatic symptoms were associated with emotional states. Children with BHSS are not considered to have serious psychological disturbances, even if they are constantly referred to as intolerant of separation, stubborn, oppositional, or easy to temper tantrum. A reduced ability to tolerate frustration is evident in these children both from the patients' history and clinical observation. Parents usually relate BHS to situations in which the child is denied something or gets scolded. The children were observed during three sessions, both with and without the mother, according to a grid used at our Center. Patients are presented to illustrate certain recurrent features in play and interaction with mother. The data suggest that these children stagnate in an area of incomplete mental representation; something makes them oscillate between two states; in one of them, the mental representation of the object and of the bond with it is possible; in the other, the mental representation of the separation, which entails the recognition of the object, is felt as dangerous. 相似文献

This research investigated how working models of attachment are carried forward from one relationship to the next. A two-part study was conducted in which participants learned about two potential dating partners: one that was constructed to resemble a romantic partner from their past and one that resembled a partner from another participant's past. Results showed that people applied their attachment representations of past partners to both targets but did so to a greater degree when the target resembled a past partner. People also tended to feel more anxious and less avoidant toward the target that resembled their past partner. Overall, the findings were consistent with the hypothesis that working models of attachment are transferred in both general and selective ways in new relationships. 相似文献

The amygdala is critically involved in discriminative avoidance learning. Large lesions of the amygdala block discriminative avoidance learning and abolish cingulothalamic training-induced neuronal activity. These results indicated that amygdalar processing is critical for cingulothalamic plasticity. The larger lesions did not allow differentiation of the specific functioning of various amygdalar nuclei. Anatomical analysis showed that damage in the central (CE) nucleus of the amygdala was correlated with the severity of the behavioral deficit. The present study was carried out to determine whether smaller lesions, centered in the CE nucleus, would impair discriminative avoidance learning and block cingulothalamic plasticity. In addition, the possible role of the CE nucleus in appetitively motivated discriminative approach learning was examined for the first time. New Zealand White rabbits with CE nuclear lesions were first trained in the discriminative approach task. After attaining asymptotic performance, discriminative avoidance training sessions were alternated with continuing approach training sessions, one session each day. The rabbits with lesions were severely impaired in avoidance learning but showed no impairment of approach learning. Surprisingly, the attenuating effects of the lesions on cingulothalamic training-induced neuronal activity were more prevalent during approach learning than during avoidance learning. These results indicated that avoidance learning can be impaired by lesions centered in the CE nucleus that leave cingulothalamic plasticity largely intact and that the CE nucleus is involved in extra-cingulothalamic learning processes. 相似文献
