社会智力研究视角和方法的转变——从社会智力的测量观到人格的社会智力观

在社会智力研究的早期,研究者们运用测量观的视角和方法对社会智力进行了研究,取得了不少的成果。但是随着研究的进行,传统测量观的发展却遇到了极大的困难,如不能对社会智力和学业智力进行有效的区分等。人格的社会智力观强调社会行为的背景具体化和行为的主观意义,主张探询人的一般化的社会认知机制,为社会智力的研究展开了一个新的视角。     

Person-organization fit: Testing socialization and attraction-selection-attrition hypotheses

Using the socialization and attraction-selection-attrition (ASA) frameworks, this study examined the relation between employees’ work values and their organization’s values (person-organization fit). With a two year time interval, 140 respondents participated in a longitudinal study. After entry, socialization served to enhance homogeneity. The work values underwent small changes and the perception of fit with the organization grew. Despite high retention rates results confirmed the attrition effect. Results indicated that the lower the perceived match between own and organizational values at entry, the more likely it was that someone left the organization over time. We concluded that socialization as well as attrition mechanisms were present at the same time.     

Precedence-effect-induced enhancement of prepulse inhibition in socially reared but not isolation-reared rats

Attention to a prepulse presented shortly before a startling stimulus enhances prepulse inhibition (PPI) of startle in normal people, but not in schizophrenics. Fear conditioning for the prepulse enhances PPI in socially reared, but not isolation-reared, rats. In humans, selective attention to acoustic signals against masking can be facilitated by precedence-effect-induced perceived spatial separation between the signal and the masker. This study investigated whether perceived spatial separation between a prepulse and a noise masker enhances PPI in socially reared rats and isolation-reared rats. The results show that both PPI and conditioning-induced PPI enhancement were larger in socially reared rats than in isolation-reared rats. More important, in socially reared, but not isolation-reared, rats, a further PPI enhancement was induced by precedence-effect-induced perceived separation between a prepulse and a masker only after the prepulse became fear conditioned. Thus, perceived separation facilitates normal rats’ attention to a conditioned prepulse and enhances PPI. Isolation rearing impairs rats’ ability to attend to ecologically significant acoustic events.     

A standardized set of 260 pictures for Modern Greek: Norms for name agreement, age of acquisition, and visual complexity

The appropriate selection of both pictorial and linguistic experimental stimuli requires a previous languagespecific standardization process of the materials across different variables. Considering that such normative data have not yet been collected for Modern Greek, in this study normative data for the color version of the Snodgrass and Vanderwart picture set (Rossion & Pourtois, 2004) were collected from 330 native Greek adults. Participants named the pictures (providing name agreement ratings) and rated them for visual complexity and age of acquisition. The obtained measures represent a useful tool for further research on Greek language processing and constitute the first picture normative study for this language. The picture norms from this study and previous ones may be downloaded from brm.psychonomic-journals.org/content/supplemental.     

句子加工的脑成像研究

近年来句子加工的脑成像研究大量涌现,并集中于揭示句子语义与语法加工的神经机制以及之间的联系。文章首先对这些研究所采用的范式加以分析与比较,从而将句子加工脑成像研究的研究思路与常用范式进行了归纳与总结。其次,讨论了语义加工与语法加工的神经机制,并根据现有的研究结果,对句子语义与语法两个成分在认知加工与神经机制上的共性与特性做出推论。最后,从语言的多样性以及影响句子加工的因素两个角度,对以后的句子加工脑成像研究做了展望。     

后见之明研究综述

后见之明指后见判断(可得益于事件结果反馈的判断)与先见判断(不知晓事件结果时的判断)的系统差异,其研究范式大体可分为两类,假定型设计和记忆型设计。后见效应的研究,具有重大的理论价值和应用价值。文章对后见效应的研究范式、研究结果、及其有关理论进行了简要综述,并对其应用价值加以评述。     

记忆研究的新取向

传统的记忆心理学实验研究,其理念是数量取向的,将记忆隐喻为储藏室;而在近期,记忆研究的理念正朝着准确取向转变,关注记忆是否与实际对应符合。文章对准确取向记忆研究的基本特征予以归纳和分析,并对其涉及的现象、问题和理论进行了介绍。     

三校大学生竞争／合作策略取向的特点及影响因素

为研究大学生竞争／合作策略取向的特点及影响因素,采用”合作与竞争策略标度”量表对144名大学生进行测查,并从能力变量、期望变量及背景变量进一步研究其影响因素。结果表明大学生竞争策略均分值普遍显著高于合作策略均分值,提示学生更崇尚竞争策略;女生的竞争策略均分值明显高于男生分值,表现出策略取向的性别差异。通过相关分析和多元逐步回归分析,表明学习能力、总体能力与父母期望对学生的竞争策略取向有一定的预测性,而性别和母亲受教育程度可部分预测学生合作策略取向。
