基于QQ空间的社交网站使用对青少年抑郁的影响:上行社会比较和自尊的序列中介作用

为探讨社交网站(QQ空间)使用对青少年抑郁的影响及其作用机制,在社会比较和抑郁易感性模型的视角下,采用社交网站使用强度问卷、上行社会比较问卷、自尊量表和抑郁量表,对964名中学生进行调查。结果表明:(1)在控制了性别、年龄以及社交网站使用年限后,社交网站使用对抑郁和社交网站中的上行社会比较都有显著的正向预测作用;(2)社交网站使用能通过社交网站中的上行社会比较和自尊的中介作用对抑郁产生影响,且该中介作用包含了两条路径——上行社会比较的单独中介作用以及上行社会比较-自尊的链式中介作用。本研究揭示了社交网站使用与抑郁的关系及其作用机制,深化了社交网站使用对个体影响的研究。     

Developing Pairwise Preference-Based Personality Test and Experimental Investigation of Its Resistance to Faking Effect by Item Response Model

Recent years have shown increased awareness of the importance of personality tests in educational, clinical, and occupational settings, and developing faking-resistant personality tests is a very pragmatic issue for achieving more precise measurement. Inspired by Stark (2002) and Stark, Chernyshenko, and Drasgow (2005), we develop a pairwise preference-based personality test that aims to measure multidimensional personality traits using a large-scale statement bank. An experiment compares the resistance of the developed personality test to faking with that of rating scale-based personality tests in the item response theory model framework. Results show that latent traits estimated from the personality test based on the rating scale method are severely biased, and that faking effect can be pragmatically ignored in the personality test developed based on the pairwise preference method.     

符号数量和非符号数量的空间表征:5岁儿童的SNARC效应和距离效应

对物理刺激的数量信息表征是符号数字表征的前提和基础,据此假设在儿童的SNARC效应发生的时序问题上,非符号数量(如面积)的空间表征早于符号数量(如阿拉伯数字)的空间表征。本研究邀请5岁幼儿完成数字比较和面积比较两类任务,结果发现在数字比较任务中没有出现SNARC效应,但却存在距离效应;在面积比较任务中出现了SNARC效应和距离效应。可以推断,在阿拉伯数字的空间表征出现之前,儿童已经能够对非符号数量信息进行空间表征。     

Testing a direct mapping versus competition account of response dynamics in number comparison†

Tracking hand movements during number tasks has become a powerful method for disentangling competing models of numerical representation. In two experiments, participants used a computer mouse to choose whether presented numbers were greater than or less than 5. In Experiment 1, trajectories became more curved towards the incorrect response as targets approached the standard 5, indicating increasing response competition. However, trajectories showed a rightward bias modulated by numerical distance and target size, indicating a direct mapping between hand movement and an ordered, spatial number representation. In Experiment 2, I changed the direction of mouse movements bottom-to-top orientation to left-to-right. Trajectories again became more curved towards the incorrect response as targets approached 5, but this time, there was no modulation of trajectory bias by target size or distance. The results call into question a direct mapping account and instead lend support to a competition model of response dynamics in number comparison.     

Common magnitude representation of fractions and decimals is task dependent

Although several studies have compared the representation of fractions and decimals, no study has investigated whether fractions and decimals, as two types of rational numbers, share a common representation of magnitude. The current study aimed to answer the question of whether fractions and decimals share a common representation of magnitude and whether the answer is influenced by task paradigms. We included two different number pairs, which were presented sequentially: fraction–decimal mixed pairs and decimal–fraction mixed pairs in all four experiments. Results showed that when the mixed pairs were very close numerically with the distance 0.1 or 0.3, there was a significant distance effect in the comparison task but not in the matching task. However, when the mixed pairs were further apart numerically with the distance 0.3 or 1.3, the distance effect appeared in the matching task regardless of the specific stimuli. We conclude that magnitudes of fractions and decimals can be represented in a common manner, but how they are represented is dependent on the given task. Fractions and decimals could be translated into a common representation of magnitude in the numerical comparison task. In the numerical matching task, fractions and decimals also shared a common representation. However, both of them were represented coarsely, leading to a weak distance effect. Specifically, fractions and decimals produced a significant distance effect only when the numerical distance was larger.     

Explaining Differences in Societal Levels of Happiness: Relative Standards, Need Fulfillment, Culture, and Evaluation Theory

This article addresses the question of which societal characteristics are likely to enhance subjective well-being. Empirical results bearing on four theories are presented: needs theory, goals theory, relative standards models, and cultural approaches. The theories are to a degree compatible, rather than completely contradictory. There is empirical support for each of the theories, but also there are data contradicting a simple formulation of each model, and no approach can by itself explain all of the extant findings. For both applied and theoretical reasons, it is imperative that we determine the types of societal characteristics that enhance subjective well-being. In this vein a model called Evaluation Theory is proposed, in which SWB depends on people's evaluations of self-relevant information. Attention is selective and therefore the factors that determine its focus are likely to influence evaluations of events. Thus, appraisals are likely to be influenced by chronically accessible information, which in turn is influenced by the person's needs, goals, and culture. Currently, salient information is seen as being a key to life satisfaction judgments. The present paper describes numerous limitations in current research suggesting studies that will allow more definitive theories to emerge.
