人类视觉系统获取颜色恒常性的认知操作特性

以光度测量为基础,采用心理物理学方法,探讨人类视觉系统获取颜色常性的认知特性。共进行了两个实验。实验一,探讨颜色对比对获取颜色常性的认知操作过程的作用。结果发现,视觉系统可根据已适应了的对比参照作用,而校正（或补偿）由于外界照明变化而引起的物理色度变化。实验二,探讨视觉经验对人类视觉系统获取颜色常性的作用。结果发现,颜色常性不仅是一种视觉低层次、自动完成的补偿,而且涉及高层次的意识活动。     

社会价值取向与反馈对动态社会两难决策的影响：以水资源两难决策为例

以水资源两难情景为实验任务,探讨了社会价值取向与反馈在社会两难决策中的作用.结果表明: (1)社会价值取向在决策者的两难决策行为中起着非常重要的作用.合作型个体比非合作型个体显著地表现出更多的合作行为.个体的社会价值取向可以作为预测两难决策行为的一个重要因素: (2)不同的反馈类型对具有不同社会价值取向的决策者的决策行为影响不同.非合作型个体受反馈信息影响比较明显,而合作型个体则不易受他人的决策信息影响.     

Is the Interdependent Self More Sensitive to Question Context Than the Independent Self? Self-Construal and the Observation of Conversational Norms

Question answering requires close attention to the common ground to determine what the questioner wants to know. Because attentiveness to others is more likely to be a self-defining goal when the self is thought of as interdependent with others rather than independent of others, we predicted that self-construal influences attentiveness to the common ground. In Experiment 1, participants' temporary self-construal was manipulated through a priming technique. As predicted, interdependence-primed participants were more likely than independence-primed participants to take the recipient's knowledge into account and avoided providing redundant information in a self-administered questionnaire. Drawing on chronic differences in self-construal, Experiment 2 replicated these findings with participants from independent (Germany) and interdependent (China) cultures. Throughout, participants' differential attentiveness to the common ground resulted in differential question order effects, raising important methodological issues for cross-cultural research.

The Thorny Relation Between Measurement Quality and Fit Index Cutoffs in Latent Variable Models

Latent variable modeling is a popular and flexible statistical framework. Concomitant with fitting latent variable models is assessment of how well the theoretical model fits the observed data. Although firm cutoffs for these fit indexes are often cited, recent statistical proofs and simulations have shown that these fit indexes are highly susceptible to measurement quality. For instance, a root mean square error of approximation (RMSEA) value of 0.06 (conventionally thought to indicate good fit) can actually indicate poor fit with poor measurement quality (e.g., standardized factors loadings of around 0.40). Conversely, an RMSEA value of 0.20 (conventionally thought to indicate very poor fit) can indicate acceptable fit with very high measurement quality (standardized factor loadings around 0.90). Despite the wide-ranging effect on applications of latent variable models, the high level of technical detail involved with this phenomenon has curtailed the exposure of these important findings to empirical researchers who are employing these methods. This article briefly reviews these methodological studies in minimal technical detail and provides a demonstration to easily quantify the large influence measurement quality has on fit index values and how greatly the cutoffs would change if they were derived under an alternative level of measurement quality. Recommendations for best practice are also discussed.     

Functional Parallel Factor Analysis for Functions of One- and Two-dimensional Arguments

Parallel factor analysis (PARAFAC) is a useful multivariate method for decomposing three-way data that consist of three different types of entities simultaneously. This method estimates trilinear components, each of which is a low-dimensional representation of a set of entities, often called a mode, to explain the maximum variance of the data. Functional PARAFAC permits the entities in different modes to be smooth functions or curves, varying over a continuum, rather than a collection of unconnected responses. The existing functional PARAFAC methods handle functions of a one-dimensional argument (e.g., time) only. In this paper, we propose a new extension of functional PARAFAC for handling three-way data whose responses are sequenced along both a two-dimensional domain (e.g., a plane with x- and y-axis coordinates) and a one-dimensional argument. Technically, the proposed method combines PARAFAC with basis function expansion approximations, using a set of piecewise quadratic finite element basis functions for estimating two-dimensional smooth functions and a set of one-dimensional basis functions for estimating one-dimensional smooth functions. In a simulation study, the proposed method appeared to outperform the conventional PARAFAC. We apply the method to EEG data to demonstrate its empirical usefulness.     

Behavioral Problems Reported by Adolescents and Parents from HIV Affected Families in China

This study examined the influence of various factors on the behavioral problems of adolescents affected by HIV while considering the agreement between adolescent and parent reports on problem behaviors. A total of 136 families each with one parent living with HIV (PLH) and one child aged 13–18 were included. Structural equation modeling was used to explore relationships between selected family measures and adolescent’s problem behaviors. The correlation between the PLH and adolescent-reported behavioral problem measures was low (β?=?0.11). PLH-reported adolescent problem behaviors were negatively related to PLH-reported parental bonding (β?=??0.39), family routines (β?=??0.26), and positively associated with family conflict (β?=?0.21). Adolescent-reported family participation was associated with self-reported problem behaviors (β?=??0.35). Our study reported discrete perceptions of adolescent problem behaviors from parents’ and adolescents’ points of view. Future intervention efforts should emphasize family contextual factors to improve behavioral outcomes in adolescents affected by HIV.
