A total of 69 preschool children were tested on measures of false belief understanding (the Unexpected Transfer task), inhibitory control (the Grass/Snow task), and strategic reasoning (the Windows task). For each task, children indicated their response either by pointing with their index finger or by using a nonstandard response mode (pointing with a rotating arrow). The means of responding had no effect on children's performance on the Grass/Snow task or on the Unexpected Transfer task, although children performed better on the Unexpected Transfer task when the key object in the story was removed. In contrast, performance on the Windows task was significantly better when children pointed with the rotating arrow. A follow-up experiment with 79 preschoolers found that this improved performance on the Windows task was sustained even after the nonstandard response mode was removed and children again pointed with their finger. These findings together suggest that nonstandard response modes do not help children to inhibit prepotent pointing responses but may help them to formulate response strategies on reasoning tasks by discouraging unreflective impulsive responding. 相似文献

Studies of social categorization have shown that humans robustly categorize others along dimensions of sex, age, kinship, and coalition. Drawing on a functional perspective, we predicted that humans should also categorize others along the dimension of morality (i.e., violating vs. upholding moral norms). In a study employing the memory confusion paradigm, university undergraduate participants (N = 39) were presented with same-sex targets randomly matched with sentences indicating violation or upholding of moral norms, and with sentences indicating competence or incompetence. Results showed that participants spontaneously categorized along morality but not along competence, suggesting that morality (beyond general valence) may be an important dimension of social categorization. 相似文献

The standard semantic definition of consequence with respect to a selected set X of symbols, in terms of truth preservation under replacement (Bolzano) or reinterpretation (Tarski) of symbols outside X, yields a function mapping X to a consequence relation \(\Rightarrow_X\). We investigate a function going in the other direction, thus extracting the constants of a given consequence relation, and we show that this function (a) retrieves the usual logical constants from the usual logical consequence relations, and (b) is an inverse to—more precisely, forms a Galois connection with—the Bolzano–Tarski function. 相似文献

This paper begins an analysis of the real line using an inconsistency-tolerant (paraconsistent) logic. We show that basic field and compactness properties hold, by way of novel proofs that make no use of consistency-reliant inferences; some techniques from constructive analysis are used instead. While no inconsistencies are found in the algebraic operations on the real number field, prospects for other non-trivializing contradictions are left open. 相似文献

The present work is motivated by two questions. (1) What should an intuitionistic epistemic logic look like? (2) How should one interpret the knowledge operator in a Kripke-model for it? In what follows we outline an answer to (2) and give a model-theoretic definition of the operator K. This will shed some light also on (1), since it turns out that K, defined as we do, fulfills the properties of a necessity operator for a normal modal logic. The interest of our construction also lies in a better insight into the intuitionistic solution to Fitch’s paradox, which is discussed in the third section. In particular we examine, in the light of our definition, DeVidi and Solomon’s proposal of formulating the verification thesis as \(\phi \rightarrow \neg \neg K\phi\). We show, as our main result, that this definition excapes the paradox, though it is validated only under restrictive conditions on the models. 相似文献

The aim of this study was to investigate the frequency with which cancer patients engage in religious and spiritual practices, the methods used, the reasons for such a search, and the levels of depression and hopelessness in patients who seek spiritual assistance. One hundred and ten radiation oncology patients, who gave voluntary informed consent were included in this study. Questionnaires about religious and spiritual practices were administered, along with the Beck Depression and Beck Hopelessness scales. Twenty percent of the patients preferred spiritual practices. Female gender, lower education levels, and higher depression and hopelessness scores were associated with this preference. The frequency of depression was 18.2%, and the frequency of hopelessness was 20.9%. A significant number of cancer patients engaged in religious and spiritual practices. We recommend that practitioners offer their patients brief but sufficient information about religious and spiritual support and determine their patients’ depression and hopelessness levels. 相似文献

The present study examined the psychological profiles of 138 candidates for ordained ministry from the Episcopal (n = 90) and Presbyterian Church (USA) (n = 48). Employing scales scores from the MMPI-2, MCMI-III, and 16PF-5, we used a series of one-way ANOVAs to test for differences
between genders, denominations, and (for Episcopalians) ordination type and completion versus non-completion of the ordination
process. Our results suggest that, consistent with the literature, these future clergy were generally well-adjusted and socially
skilled. Denominational differences in our sample were virtually non-existent. While similar on most dimensions, female candidates
may appraise their circumstances and relationships with a greater emphasis on emotional considerations than their male counterparts.
Differences between Episcopal candidates for the Priesthood and the Deaconate were consistent with differences in their respective
leadership and support roles. Finally, discriminant function analysis indicated that candidates who completed their ordination
appeared to have a more realistic and positive attitude toward the process as well as a more deferential and less independent
orientation than those who did not. 相似文献

The vocation of clergy life can be a hazardous journey. Stress and burnout are issues, which are increasingly reported by
clerics. Burnout is defined by a constellation of work related symptoms (Doolittle, Mental Health, Religion & Culture,10(1),
31–38, 2007), with emotional exhaustion recognised as a core component. Despite this recognition the research has not focused on factors
which lead to this state of emotional exhaustion in particular secondary traumatization. The purpose of this article is threefold.
Firstly, it presents the theoretical framework of secondary trauma. Secondly it reviews the literature aligning clergy and
trauma work and thirdly it discuses the emotional and physical toll upon clergy from this aspect of their role. 相似文献

An important constraint on the nature of intrinsic value---the “Supervenience Principle” (SP)---holds that some object, event,
or state of affairs ϕ is intrinsically valuable only if the value of ϕ supervenes entirely on ϕ's intrinsic properties. In this paper, I argue that SP should be rejected. SP is inordinately restrictive. In particular,
I argue that no SP-respecting conception of intrinsic value can accept the importance of psychological resonance, or the positive
endorsement of persons, in explaining value. 相似文献
