大学生人际信任与主观幸福感的关系:亲社会行为与攻击行为的中介作用

为考察大学生的人际信任对主观幸福感的影响机制以及亲社会行为和攻击行为的中介作用,采用人际信任问卷、亲社会行为问卷、攻击行为问卷、幸福感指数问卷对2256名大学生进行调查。研究结果显示:(1)人际信任正向预测大学生的主观幸福感,人际信任水平越高,主观幸福感越好;(2)人际信任通过亲社会行为与攻击行为的中介作用,间接影响主观幸福感。

Picture versus question elaboration on young children's learning of sentences containing high- and low-probability content

The main purpose of the two experiments reported here was to compare the potency of two types of elaboration on children's learning of sentence content: The effects of partial picture adjuncts were compared to the effects produced by answering "why"-questions about the relationships specified in the sentences. Five- to seven-year-old children heard sentences of the form, subject/verb/direct object/preposition/instrument. Sentences contained either a high-probability or a low-probability instrument given the semantic context. In Experiment 1, sentences either were accompanied by a partial picture depicting the sentence action but omitting the instrument or were presented without a partial picture accompaniment. Recall was improved by provision of partial pictures at study. In Experiment 2, the sentences were accompanied by complete pictures depicting the sentence content. In both experiments, questioning significantly reduced recall of high-probability sentences, with recall of instruments affected especially negatively. Evidence is presented that insufficient attention to instruments may have been one mechanism mediating depressed recall of high- compared to low-probability instruments in the questioned conditions. In summary, partial pictures improved cued recall of sentences in this study; in contrast, all significant effects produced by answering why-questions were negative ones (i.e., later recall was reduced following interrogation at study).     

Colour, world and archimedean metaphysics: stroud and the quest for reality

This paper proposes a fundamentally opposite conception of the possibility of metaphysics to that of Barry Stroud in The Quest for Reality and other writings. I discuss Stroud’s views on everyday ‚truth’ and metaphysics (Section 1), on interpretation (Section 2 – replying with a theory of ‚quasi-understanding’), and his ‚no threat’ claim (Section 3). But the main argument (Section 4) is a response to Stroud’s claim that we have no right either to affirm or to deny the metaphysical reality of colours. Stroud’s view resembles Carnap’s (1950, Revue Internationale de Philosophie 4, 20–40), that experience can in some sense never settle the metaphysical issue between e.g. materialism, idealism and phenomenalism; though we can allow everyday ‚knowledge’ e.g. that there is a fallen tree in the garden outside, as something available on all three views. (Carnap takes the undecidability as a sign that the metaphysical issue is a pseudo-question; Stroud insists it is factual, but places it beyond our ken, ‚external’.) I argue, instead, that metaphysical argument is possible from within our conceptual scheme and epistemic situation (as in Gareth Evans’s arguments for realism over phenomenalism); that ‚external’ and ‚internal’ questions cannot be separated as Stroud wishes; and that if we really were denied knowledge on ‚metaphysical’ matters, that would infect our right to claim knowledge of ‚observational’ matters too. And I sketch a theory of colour that would allow us to conclude (at once ‚metaphysically’ and ‚internally’) that things are indeed ‚really’ coloured. For all his expressions of sympathy for Wittgenstein, Stroud’s metaphysics is remarkably Cartesian.     

Serotonin transporter (5-HTTLPR) genotype, childhood abuse, and suicide attempts in adult psychiatric inpatients

There is growing evidence that a functional polymorphism in the serotonin transporter gene (5-HTTLPR) moderates the impact of negative life events (e.g., childhood abuse) on the development of depression. However, it is unclear whether the gene x environment interaction predicts suicide attempts specifically. In addition, previous studies have not examined different forms of childhood abuse separately. In the current study, we found that 5-HTTLPR genotype moderated the link between childhood physical and sexual, but not emotional, abuse and adult psychiatric inpatients' histories of suicide attempts.     

Without Intuitions

This paper criticizes Analytic philosophy with its reliance on intuitions in pursuit of conceptual analysis. Rejecting naturalism as an alternative philosophical method, I offer in its place a pragmatic and revisionary conception of philosophical method. I explain the method of Analytic philosophy and show why reliance on intuitions is essential to that method, which is unable to provide substantive answers to philosophical problems. I further show that reflective equilibrium or wide analysis requires some criterion of intuition choice and that this criterion can be applied directly to definitions themselves.     

The effect of segmental order on fricative labeling by children and adults

We examined whether children modify their perceptual weighting strategies for speech on the basis of the order of segments within a syllable, as adults do. To this end, fricative-vowel (FV) and vowel-fricative (VF) syllables were constructed with synthetic noises from an/[symbol: see text]/-to-/s/continuum combined with natural/a/and/u/portions with transitions appropriate for a preceding or a following /[symbol: see text]/or/s/. Stimuli were played in their original order to adults and children (ages of 7 and 5 years) in Experiment 1 and in reversed order in Experiment 2. The results for adults and, to a lesser extent, those for 7-year-olds replicated earlier results showing that adults assign different perceptual weights to acoustic properties, depending on segmental order. In contrast, results for 5-year-olds suggested that these listeners applied the same strategies during fricative labeling, regardless of segmental order. Thus, the flexibility to modify perceptual weighting strategies for speech according to segmental order apparently emerges with experience.     

Displaced aggression is alive and well: a meta-analytic review

Content analysis of 122 social psychology textbooks confirmed that displaced aggression received a surge of attention immediately following J. Dollard, L. W. Doob, N. E. Miller, O. H. Mowrer, and R. R. Sears (1939), but subsequent interest sharply declined. Contemporary texts give it little attention. By contrast, meta-analysis of the experimental literature confirms that it is a robust effect (mean effect size = +0.54). Additionally, moderator analyses showed that: (a) The more negative the setting in which the participant and target interacted, the greater the magnitude of displaced aggression; (b) in accord with N. E. Miller's (1948) stimulus generalization principle, the more similar the provocateur and target, the more displaced aggression; and (c) consistent with the contrast effect (L. Berkowitz & D. A. Knurek, 1969), the intensity of initial provocation is inversely related to the magnitude of displaced aggression.     

乳腺癌术式的演变及其最佳选择

乳腺癌作为女性常见的恶性肿瘤之一,一直是肿瘤学界研究的热点和焦点。手术作为其基本的治疗手段,术式几经改变。通过对乳腺癌术式演变的历史回顾,认为正是由于对乳腺癌生物学行为研究的不断深入,使得乳腺癌手术切除范围更趋于规范和科学。而由生物医学模式向生物—心理—社会医学模式的转变,以及循证医学(EBM)研究的开展,更促进了乳腺癌术式的不断改进,以最大程度减少并发症,获得更为满意的疗效。
