心算加工中tie effect的加工机制

tie effect主要表现为tie比nontie更快更准确解决,以及tie/nontie与问题大小的交互作用,较大题目的tie比nontie具有更明显的反应时优势,tie的问题大小效应比nontie要小的多。有关tie effect加工机制的解释主要有基于编码的理论和基于结果通达的理论。目前的研究主要通过操作问题呈现方式以及报告加工策略的方法分别考察编码方式及加工策略的影响,今后研究应开拓新的研究范式以加深对其加工机制的认识。     

Salience of physical appearance characteristics among young women in Thailand

Our aim in the present study was to identify key components of physical appearance among young Thai women. Free listings, focus groups and pile sorting were used. One-hundred twenty young women generated 78 unique physical appearance characteristics. Ninety-four nursing students validated these characteristics in focus groups and then sorted them into piles that reflected separate domains of physical appearance and labeled them. Salience analysis revealed that facial appearance (e.g., bright facial skin, high nose bridge, big eyes) was the most important domain, followed by body weight and shape, skin color and texture, hair (color, texture, length), and ‘other’ physical appearance (e.g., slender neck, slim fingers). This is the first study to identify aspects of physical appearance that are most salient to young Thai women and that may differ from women in other cultural contexts. These findings could be used to develop culturally grounded measures of physical appearance in Thai women.     

Discriminating between the effects of valence and salience in the Implicit Association Test

The Implicit Association Test (IAT) is the most widely used indirect measure of attitudes in social psychology. It has been suggested that artefacts such as salience asymmetries and familiarity can influence performance on the IAT. Chang and Mitchell (2009) proposed that the ease with which IAT stimuli are classified (classification fluency) is the common mechanism underlying both of these factors. In the current study, we investigated the effect of classification fluency on the IAT and trialled a measure-the split IAT-for dissociating between the effects of valence and salience in the IAT. Across six experiments, we examined the relationship between target classification fluency and salience asymmetries in the IAT. In the standard IAT, the more fluently classified target category was, all else being equal, compatible with pleasant attributes over unpleasant attributes. Furthermore, the more fluently classified target category was more easily classified with the more salient attribute category in the split IAT, independent of evaluative associations. This suggests that the more fluently classified category is also the more salient target category.     

An empirical analysis of online gamers' perceptions of game items: modified theory of consumption values approach

The aims of this article are (1) to propose a modified theory of consumption values (MTCV) for investigation of online gamer perceptions of the value of purchasable game items and (2) to apply the developed MTCV to multiple game genres and player age groups. To address these aims, 327 valid questionnaires were obtained and analyzed. The original theory of consumption values (TCV) was modified to apply to the specific characteristics of online games. The original TCV specifies five types of consumption values: functional value, social value, emotional value, conditional value, and epistemic value. After revising the TCV to apply to the examination of online games, we proposed that the MTCV be composed of character competency value, enjoyment value, visual authority value, and monetary value. The validity of the MTCV was proven by statistically analyzing the responses provided by the 327 valid questionnaires. To examine the second aim, experiments were conducted to examine the MTCV in three online game genres-massive multiplayer online role-playing games, first-person shooters games, and casual games. The second aim was also studied via questionnaires that examined the ages of online gamers. It was determined that massive multiplayer online role-playing games players regard visual authority value and monetary value as more important than do casual gamers. It was also determined that younger gamers tend to be more interested in visual authority, whereas older gamers tend to be more interested in character competency. This research provides a foundation for future studies to extend the MTCV to consider other user factors, such as cultural effects.     

高中生自我和谐与心理健康的相关研究

目的:了解高中生自我和谐总体状况、心理健康状况及其关系。方法:采用《自我和谐量表》(SCCS)和《中学生心理健康问卷》对湖南、贵州四所中学的高中生进行测量。结果:高中生自我和谐情况不太理想;高中生在不和谐因子得分与大学生常模并无显著差异,在灵活性上差异非常显著(p<0.001),在刻板性上差异显著(p<0.05);高中生自我与经验的不和谐、刻板性、自我和谐总分均与心理健康各因子呈显著正相关;自我的灵活性与心理健康总分、偏执、敌对、适应不良等呈正相关。结论:高中生自我和谐与心理健康存在显著的相关性,自我和谐对心理健康具有一定的预测作用,培养高中生的自我和谐性有助于提高其心理健康水平。     

A preliminary study of perfectionism and loneliness as predictors of depressive and anxious symptoms in Latinas: a top-down test of a model

In the present study, we used a top-down approach to examine perfectionism and loneliness as additive sociocognitive predictors of depressive and anxious symptoms in a sample of 121 Latina college students. Consistent with expectations, we found perfectionism and loneliness to be associated with both depressive and anxious symptoms. In addition, results of conducting hierarchical regression analyses indicated that certain dimensions of perfectionism, especially doubts about actions, accounted for significant variance in both depressive and anxious symptoms. Moreover, the inclusion of loneliness as a predictor was found to predict additional unique variance in both depressive and anxious symptoms beyond what was accounted for by perfectionism. Implications of the present findings for future research on negative affective conditions in Latinas are discussed.

MRI对儿童难治性、局灶性癫痫的临床诊断及预后判断

癫痫外科的临床病理研究表明,儿童局灶性皮质发育不良(FCD)及海马硬化是儿童难治性局灶性癫痫常见的致病因素。但在术前的常规的MRI检查中,这些结构上的异常经常被忽视,从而造成延误诊断。临床医生在阅片判断上的失误可能是一个原因,但癫痫的影像专业知识的不全面是重要因素。本文结合MRI技术在癫痫临床诊断领域的应用进展,阐述了儿童难治性、局灶性癫痫患者MRI影像中可能出现的结构性病变;重点阐述了临床易于忽视的局灶性皮质发育不良(FCD)及海马硬化的MRI研究、应用进展。     

生态危机的根源及其解决方法:马克思主义经济学的视角

经济学中的不同流派对生态危机问题进行了深入的研究,但该领域的主导范式坚持认为自然资源的合理定价和资源市场的完善能够解决环境恶化问题,并对马克思主义经济学的洞见保持沉默,否认环境问题和特定的生产方式存在必然的联系.马克思主义经济学在环境问题产生的根源分析和根本的解决方法的寻找方面具有独特的价值.对当代资本主义生产方式进行彻底的变革可能是真正解决造成环境恶化的个人理性与集体理性困境的关键.
