知识背景效应对分类加工过程影响的眼动研究

在目标匹配范式下,使用表示现实生活中的物体和场景关系的手绘黑白图片材料,通过眼动记录法考察了68名知识背景不同的文理科大学生分类加工过程的差异。结果表明,知识背景对大学生分类加工过程有影响,其主要作用于分类加工的首次加工阶段。文科学生在首次加工中对问题区分配的注意多于选项区,而理科学生对问题区和选项区平均分配注意。文科生相对于理科生能够更早的注意到正确选项,在加工中重视对上位概念概括(问题区目标概念)和下位概念与上位概念间(选项区待分类概念和目标概念)的比较,而理科生更加重视同水平概念间的比较。     

Challenging sex segregation: A philosophical evaluation of the football association’s rules on mixed football

The Football Association (FA) has been under pressure to allow girls to play in mixed teams since 1978, following 12-year old Theresa Bennett’s application to play with boys in a local league. In 1991, over a decade after Bennett’s legal challenge, the FA agreed to remove its ban on mixed football and introduced Rule C4 in order to permit males and females to play together in competitive matches under the age of 11. More recently, following a campaign by parents, coaches, local Members of Parliament and the Women’s Sport Foundation, the FA agreed to trial mixed football for the under-12 to under-15 age categories in order to establish, among other things, the risk of injury to players in sex-integrated competitions. A series of exponential changes ensued: between 2010 and 2014, the age at which mixed football was permitted increased from U11 to U16. In 2015, the FA announced the decision to raise the age limit on mixed football from U16 to U18 for the forthcoming 2015–2016 season. We critically examine the reasons given by the FA for enforcing segregated participation beyond the age of 18, namely that males have an unfair advantage and that females face an unacceptable risk of injury. We also discuss the argument that removing the ban might harm the women’s game. In conclusion, we suggest that the FA ought to abandon the ban on mixed football over the age of 18.     

Can Patriots Be Critical after a Nationalist War? The Struggle Between Recognition and Marginalization of Dissenting Voices

Previous research suggests that the relationship between ingroup identification and reactions to moral violations perpetrated by ingroup members depends on the mode of identification: while glorification lowers group‐based guilt, critical attachment enhances it. In our first study, based on comparative survey research, this pattern was replicated in Serbia, but not in Croatia. In Croatia, highly attached respondents tended to reject criticism of the past war irrespective of their mode of identification. In a second study, we sought to explain the Croatian results by examining how critical attachment is denied legitimacy. We analyzed the rhetorical structure of a parliamentary debate around regime‐critical media coverage. The analyses show how the marginalization of critics is anchored in (1) a monolithic construction of the nation, which sacralizes particular elements and places them beyond discussion, and (2) a construction of the international context as too threatening to permit any dissent. Overall, the results of this mixed‐method study highlight that the opportunity to be recognized as a critical patriot depends on a nation's sociopolitical climate.     

Reliability of a Longitudinal Sequence of Scale Ratings

Reliability captures the influence of error on a measurement and, in the classical setting, is defined as one minus the ratio of the error variance to the total variance. Laenen, Alonso, and Molenberghs (Psychometrika 73:443–448, 2007) proposed an axiomatic definition of reliability and introduced the R _T coefficient, a measure of reliability extending the classical approach to a more general longitudinal scenario. The R _T coefficient can be interpreted as the average reliability over different time points and can also be calculated for each time point separately. In this paper, we introduce a new and complementary measure, the so-called R _Λ , which implies a new way of thinking about reliability. In a longitudinal context, each measurement brings additional knowledge and leads to more reliable information. The R _Λ captures this intuitive idea and expresses the reliability of the entire longitudinal sequence, in contrast to an average or occasion-specific measure. We study the measure’s properties using both theoretical arguments and simulations, establish its connections with previous proposals, and elucidate its performance in a real case study.

结构、任务类型和导航对超文本信息搜索的影响

通过两个实验考察了结构、任务类型和导航对超文本信息搜索绩效的影响。实验一采用2（层次结构,混合结构）×2（特定任务,关系任务）的被试内设计,探讨了超文本结构和任务类型对信息搜索的影响;实验二在实验一的基础上,采用2（层次结构,混合结构）×2（有导航图,无导航图）的被试内设计,考察超文本结构和导航对关系任务信息搜索的影响。结果表明：（1）超文本结构和任务类型对信息搜索绩效有显著的交互影响,就关系任务而言,混合结构超文本优于层次结构超文本,但就特定任务而言,两者无显著差异;（2）导航对信息搜索行为有指导作用,尤其对层次结构超文本有利;（3）两种主观指标的结果与客观指标存在一定程度的一致性。     

如何描述发展趋势的差异：潜变量混合增长模型

在追踪研究中,研究者不仅关心某一特质随时间的发展趋势,而且关注个体之间发展趋势的差异及其存在差异的原因。在总体发展同质的情形下,多层线性模型和潜变量增长曲线模型为解决这一问题提供了切实有效的方法。但是如果所研究的总体本身不同质,就需要一种能够描述总体中不同质子总体的不同发展特点的方法。该文简要介绍了一种能够描述不同群体不同发展趋势特征的统计模型——潜变量混合增长模型,并通过一个实际例子介绍了这一方法的应用过程,同时说明了潜变量混合增长模型与多层线性模型和潜变量增长曲线模型之间的关系
