The problem of how to remove information from an agent's stock of beliefs is of paramount concern in the belief change literature. An inquiring agent may remove beliefs for a variety of reasons: a belief may be called into doubt or the agent may simply wish to entertain other possibilities. In the prominent AGM framework for belief change, upon which the work here is based, one of the three central operations, contraction, addresses this concern (the other two deal with the incorporation of new information). Makinson has generalised this work by introducing the notion of a withdrawal operation. Underlying the account proffered by AGM is the idea of rational belief change. A belief change operation should be guided by certain principles or integrity constraints in order to characterise change by a rational agent. One of the most noted principles within the context of AGM is the Principle of Informational Economy. However, adoption of this principle in its purest form has been rejected by AGM leading to a more relaxed interpretation. In this paper, we argue that this weakening of the Principle of Informational Economy suggests that it is only one of a number of principles which should be taken into account. Furthermore, this weakening points toward a Principle of Indifference. This motivates the introduction of a belief removal operation that we call severe withdrawal. We provide rationality postulates for severe withdrawal and explore its relationship with AGM contraction. Moreover, we furnish possible worlds and epistemic entrenchment semantics for severe withdrawals. 相似文献

Infant social withdrawal is a risk factor for non-optimal child development; thus, it is important to identify risk factors associated with withdrawal. In a large community sample (N = 19,017), we investigate whether symptoms of maternal and partner postpartum depression (PPD; measured with the Edinburgh Postnatal Depression Scale) and prematurity are predictors of infant social withdrawal (measured with the Alarm Distress Baby Scale). Withdrawal was assessed at 2–3, 4–7 and 8–12 months postpartum. Linear regressions showed that prematurity predicted higher infant social withdrawal at all time points, and maternal symptoms of PPD were positively associated with withdrawal at 2–3 months. Logistic regressions showed that odds for elevated social withdrawal were increased with elevated levels of maternal symptoms of PPD at 2–3 and 8–12 months. Partner's symptoms of PPD were not associated with withdrawal. Future studies should investigate how PPD symptoms and prematurity may impact the individual development of social withdrawal. 相似文献

The aim of this analysis was to explore whether pre-treatment intervention preferences were related to outcomes for patients with persistent sub-threshold and mild depression who received one of two treatment types. Thirty-six patients took part in a two-arm, parallel group, pilot randomized controlled trial that compared short term (3 month and 6 month) outcomes of person-centred counselling (PCC) compared with low-intensity, CBT-based guided self-help (LICBT). Patient preferences for the two interventions were assessed at baseline assessment, and analysed as two independent linear variables (pro-PCC, pro-LICBT). Eight out of 30 interactions between baseline treatment preferences and treatment type were found to be significant at the p < .05 level. All were in the predicted direction, with patients who showed a stronger preference for a treatment achieving better outcomes in that treatment compared with the alternative. However, pro-LICBT was a stronger predictor of outcomes than pro-PCC. The findings provide preliminary support that treatment preferences should be taken into account when providing interventions for patients with persistent sub-threshold and mild depression. It is recommended that further research analyses preferences for different treatment types as independent variables, and examines preferences for format of treatment (e.g. guided self-help vs. face-to-face). 相似文献

This paper discusses the view that fantasizing, understood as a flight into fantasy, belongs to a type of mental functioning distinct from imaginative fantasy. From this the idea emerges, proposed by Winnicott, that withdrawal into fantasy assumes a dissociative quality, which is formed early on as a defensive solution following the loss of hope in object relations. Such a defence becomes the foundation for a dangerous enclave in which the individual ends up enclosing himself, experiencing an illusory self-sufficiency. In this perspective, the author maintains that the flight into fantasy must be understood as a risk factor for the draining of the self or for a crystallization into psychopathological structures, becoming an automatic activity of 'non-thought' that substitutes for the working-through processes necessary for the development of the mind. The paper investigates this psychopathological dynamic, which was already present in Breuer and Freud's writings, examining subsequent contributions of various authors. Clinical material (of both children and adults) illustrates how the flight into fantasy may take the form of an anti-relational realm of the mind, compromising the operations necessary to the integration of psychic life. There is also a discussion of which therapeutic tools may help the patient to gradually abandon the withdrawal in favour of an authentically nourishing relational nature. 相似文献

We investigated the relations between anticipation of sadness for excluded peers, sympathy, and prosocial behavior in a sample of 127 Italian preschoolers (Mage?=?4.84?years, SD?=?0.85). Children attributed emotions to hypothetical excluded peers who exhibited withdrawn versus aggressive behavior, and these attributions were coded for the presence and intensity of sadness. Teachers rated children’s sympathy and prosocial behavior via questionnaire. In general, children attributed more sadness to the withdrawn excluded peer than the aggressive excluded peer. A path analysis revealed that those who anticipated higher levels of sadness for the withdrawn excluded peer were rated higher in sympathy and, in turn, higher in prosocial behavior. Attributing high levels of sadness to withdrawn excluded peers—who portray relatively heightened need—may be an early social-emotional characteristic of children who are more sympathetic and more likely to channel other-oriented concerns into prosocial actions. 相似文献

ABSTRACTAt present, the consequences and functions of experiences of shame are not yet well understood. Whereas psychology literature typically portrays shame as being bad for social relations, motivating social avoidance and withdrawal, there are recent indications that shame can be reinterpreted as having clear social tendencies in the form of motivating approach and social affiliation. Yet, until now, no research has ever put these alternative interpretations of shame-motivated behaviours directly to the test. The present paper presents such a test by studying the extent to which shame motivates a preference for social withdrawal versus a preference for social approach. Two studies (N?=?148 and N?=?133) using different shame inductions both showed people experiencing shame to prefer to be together with others (social approach) over being alone (social withdrawal). In addition, the preference for a social situation was found to be unique for shame; it was not found for the closely related emotion of guilt. Taken together, these findings provide direct empirical support for the idea that shame can have positive interpersonal consequences. 相似文献
