Context-dependent alarm responses in wild vervet monkeys

Effect of perceived public stigma on internalized homophobia,anticipated stigma,shame, and guilt: Outness as a moderator

Although previous studies found that distal minority stress contributes to proximal minority stress and shame/guilt among the lesbian, gay, and bisexual (LGB) population, it is unclear whether the extent to which LGB individuals' open display and discussion their sexual orientation moderates these relationships. A total of 1,452 Chinese LGB adults provided demographic information and completed measures of outness, perceived public stigma, internalized homophobia, anticipated stigma, shame, and guilt. Structural equation modelling was conducted to test the hypothesized moderation analyses. Perceived public stigma had positive associations with internalized homophobia, anticipated stigma, shame, and guilt. Outness played a moderating role in the associations of perceived public stigma with internalized homophobia, anticipated stigma, shame, and guilt. Specifically, when LGB individuals had higher levels of outness, the effects of perceived public stigma on internalized homophobia, anticipated stigma, shame, and guilt were lower. Moreover, such moderating effect did not differ by sexual orientation. The degree to which sexual minority individuals' sexual orientation is known by and openly discussed with others may lower the extent to which LGB individuals internalize sexual stigma, expect rejection after coming out, and develop shame and guilt as a result of perceived social prejudice and discrimination.     

A rich palette of Bible use: A theoretical and empirical contribution from the context of Protestant Christian primary schools in the Netherlands

The aim of this study is to gain empirical knowledge about how the Bible functions in the context of Protestant Christian primary schools in the Netherlands. It presents the results of an empirical explorative and qualitative study on the perceptions of teachers and school administrators (directors and internal supervisors) on the goals of Bible use in Protestant primary education, as well as the roles of teachers and pupils, and how these can be understood in terms of religious pedagogical models and theories. Five small focus group interviews with teachers and six interviews with school administrators revealed a variety of goals teachers hold regarding Bible use in education and a variety of divisions of teacher–learner roles in this regard. The findings also show some particular characteristics when compared with secondary schools.     

The Persistent Interlocutor

A Persistent Interlocutor (PI) is someone who, in argumentative contexts, does not cease to question her opponent’s premises. The epistemic relevance of the PI has been debated throughout the history of philosophy. Pyrrhonians famously claim that our inability to dialectically vindicate our claims against a PI implies scepticism. Adam Leite disagrees (2005). Michael Resorla argues that the debate is based on a false premise (2009). In this paper, I argue that these views all fail to accurately account for the epistemic relevance of the PI. I then briefly present an account that aims to do better in this regard, based on the modal notion of safety. On the account proposed, the PI does not violate epistemic or dialectical norms. Rather, her behaviour tends to be epistemically perverse in the sense that it wastes cognitive resources. Perhaps surprisingly, this defect turns out not to be unique to the PI.

     

Early judgments of semantic and syntactic acceptability by children

Judgments of the acceptability of correct, word order reversed, and semantically anomalous sentences were elicited from 2- and 3-year-old children in a game played with hand puppets. All of the sentences used were simple imperatives and each child was asked to correct those he called wrong. Performance on the judgment task was correlated with each child's mean length of utterance and with his comprehension of reversible active and passive sentences. Only the linguistically most advanced children were able to make a significant number of appropriate judgments and corrections of reversed word order imperatives. Less developed children could appropriately judge and correct semantically anomalous but not incorrect word order imperatives. The importance of semantic as opposed to syntactic factors in children's judgments of the acceptability of sentences is stressed.This research was supported in part by PHS Grant HD-02908 from the National Institute of Child Health and Development.

影响不同方位刺激观察的若干因素的初步研究

对于不同方位刺激的观察及多种刺激呈現的观察定位問題,作者已在前一研究报告中討論了,但对被試所处的不同状态(包括被試的主观条件)对刺激的观察起什么影响,我們尚很少涉及。早在1905年阿赫(N.Ach)和华特(H.J.Watt)就发現,对刺激反应的快慢,依賴于被試的准备状态,即被試当时所处的主观状态。波芬貝格(A.T.Poffen-     

主客体的不同角度倾斜对深度辨别的影响

影响深度辨别的因素,如目标物的长度、寬度、移动速度、垂直距离、背景照明以及不同的地表面等等,前人已作过許多研究。但是,这些研究都是观察者与目标物均处于正直的状态下进行的。至于观察者或目标物处于不同角度的傾斜状态下,对深度辨别有何影响,在文献中还較罕見。沃克(R. Y. Walker)曾作过这类研究,他以豪瓦德-多尔曼     

Shape from stereo: A systematic approach using quadratic surfaces

We used quadratic shapes in several psychophysical shape-from-stereo tasks. The shapes were elegantly represented in a 2-D parameter space by the scale-independentshape index and the scale-dependentcurvedness. Using random-dot stereograms to depict the surfaces, we found that the shape of hyperbolic surfaces is slightly more difficult to recognize than the shape of elliptic surfaces. We found that curvedness (and indirectly, scale) has little or no influence on shape recognition.
