The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas

Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, 2004). The authors simulated 1 experiment from each study in a virtual reality environment to test whether experimental results could be explained by view-based navigation. The authors recorded a reference image at the target location and then determined global panoramic image differences between this image and images taken at regularly spaced locations throughout the arena. A formal model, in which an agent attempts to minimize image differences between the reference image and current views, generated trajectories that could be compared with the search performance of rats. For both experiments, this model mimics many aspects of rat behavior. View-based navigation provides a sufficient and parsimonious explanation for a range of navigational behaviors of rats under these experimental conditions.     

有自杀意念大学生的内隐态度探析

该文结合Greenwald开创的内隐联想测验,自编IAT程序,对有自杀意念大学生的内隐态度进行了相关研究。结果显示,有自杀意念大学生较无自杀意念大学生的内隐态度对自杀类词语敏感等。家庭所在地为农村对有自杀意念大学生的内隐态度有显著性影响。     

道教"贵柔守雌"思想对贾平凹小说的影响

道教"贵柔守雌"的伦理思想主张男女平等,这一点对贾平凹继<废都>后的小说创作有着明显的影响,也委婉地导致了他的小说中女性角色的定位由误读回归到人格化塑造的道路.反映在小说中,则具体表现为道教隐士和充满道教意蕴的意象对女主人翁的感情与人格发展的塑造性的影响.本论文就这种隐性的创作转交作一梳理,揭示道教"贵柔守雌"思想在其中发挥的作用.     

同步内隐／外显序列学习：事件相关的fMRI的初步研究

本文利用事件相关fMRI研究探讨对于内隐和外显学习在脑区激活上的差异.实验采用同步内隐/外显学习序列,以有色的形状作为刺激材料.要求被试对于刺激的颜色做选择反应,并在颜色消失后找出形状的内在规则.颜色和图形序列分别采用两个独立的马尔可夫链,即下一个图形的颜色或者形状有70%的可能服从序列规则.行为数据显示被试习得了外显和内隐的规则,fMRI成像主要比较内隐和外显学习在学习过程和知识运用上脑区激活的差异.结果发现,与内隐学习柑比,外显学习在额叶的激活更为显著.而且,内隐学习和外显学习在视觉皮层的激活出现分离,内隐学习中枕叶的激活减弱,而外显学习中枕叶的激活增加.     

多元概化理论在评定量表编制中的作用——以音像教材测评数据分析为例

目前多元概化理论已开始在考试、评价领域得到应用,但是很少有研究者关注其对评定量表编制的作用.本文认为多元概化理论的G研究可以估计各种效应带来的变异,能够据此(1)考察评定量表各维度和总体信度;(2)确定评定量表各维度的权重;D研究可以评估各种测量方案的信度,能够据此(3)确定评定项目的数量.这三个方面都是编制评定量表必不可少的环节,本文采用音像教材的测评数据,用实证方法展示多元概化理论对评定量表编制的指导作用.     

Predicting Marital Satisfaction From Self,Partner, and Couple Characteristics: Is It Me,You, or Us?

Past research on the link between personal characteristics and marital satisfaction has taken either an individual or a dyadic approach. The individual approach examines how self and/or partner characteristics are associated with satisfaction, whereas the dyadic approach focuses on couple characteristics such as couple similarity. The current research was designed to integrate both approaches. A modified Actor-Partner Interdependence Model (Kashy & Kenny, 2000) was proposed to test simultaneously the contributions of self characteristics, partner characteristics, and two types of couple similarity (level similarity measured by the absolute difference score and shape similarity measured by the profile correlation) in predicting husbands' and wives' marital satisfaction. This model was tested by structural equation modeling in two large, nationally representative, urban samples (N=536 and 537 couples) from China. The results were largely replicated across four personality domains and two value domains, suggesting that all predictors tended to make independent contributions to satisfaction except the absolute difference score.

Validity of the GDS-4 revisited

This article points out several flaws in an earlier article (Chau, Martin, Thompson, Chang, & Woo, 2006). We note that Chau, Martin, Thompson, Chang, and Woo (2006) had misquoted our work on a 4-item version of the geriatric depression scale (GDS), and the work of the research team, which developed the original 30-item and 15-item versions of the scale. Furthermore, their data analytic methods were flawed, and their conclusions were often not supported by the data they presented. On the basis of these observations, we found no evidence against the use of the 4-item version of the GDS.     

Whither geometry? Troubles of the geometric module

In rectangular arenas, rats often confuse diagonally opposite corners, even when distinctive cues differentiate them. This led to the postulation that rats rely preferentially on the geometry of space, encoded in a dedicated geometric module. Recent research casts doubt on this idea. Distinctive featural cues such as entire walls of a distinct color can hinder or aid the learning of geometry. In one situation in which using geometry would help greatly, rats had trouble learning the task. An associative model has been developed to capture these different learning processes, and view-based matching has been proposed as an alternative to the explicit coding of geometric cues. Considerations about how cues interact in learning are crucial in a recent theory of human spatial cognition.     

The individual-oriented and social-oriented Chinese bicultural self: testing the theory

The author proposes a bicultural self theory for contemporary Chinese individuals, encompassing 2 main components: the individual-oriented self and the social-oriented self. The social orientation is rooted in traditional Chinese conceptualization of the self, whereas the individual orientation has evolved and developed under Western influences along with recent societal modernization. The author conducted a series of 5 studies to test the theory and relate the model to important issues in current personality and social psychological research, such as cultural individualism-collectivism, self-construals, motivation, cognition, emotion, and well-being. A total of 977 university students in Taiwan participated. The author found that contrasting self-aspects were differentially associated with the aforementioned constructs, as theoretically predicted. This evidence thus generally supported the bicultural self model.
