The weckud wetch of the wast: lexical adaptation to a novel accent

Two experiments investigated the mechanism by which listeners adjust their interpretation of accented speech that is similar to a regional dialect of American English. Only a subset of the vowels of English (the front vowels) were shifted during adaptation, which consisted of listening to a 20-min segment of the "Wizard of Oz." Compared to a baseline (unadapted) condition, listeners showed significant adaptation to the accented speech, as indexed by increased word judgments on a lexical decision task. Adaptation also generalized to test words that had not been presented in the accented passage but that contained the shifted vowels. A control experiment showed that the adaptation effect was specific to the direction of the shift in the vowel space and not to a general relaxation of the criterion for what constitutes a good exemplar of the accented vowel category. Taken together, these results provide evidence for a context-specific vowel adaptation mechanism that enables a listener to adjust to the dialect of a particular talker.     

Auditory and haptic systems for in-car speed management – A comparative real life study

Field experiments with ISA (intelligent speed adaptation) were carried out in Hungary and Spain in 2003 and 2004, respectively. Twenty private vehicles in each country were equipped with two kinds of systems: (1) support via an active accelerator pedal (AAP) and (2) warning via beep signals and a flashing red light when the speed limit was exceeded (BEEP). The test drivers drove for a month with both systems installed in each car. Speed was continually logged in all the vehicles and the test drivers were interviewed about their acceptance and experiences of the systems. The results show that both systems reduced the mean and 85 percentile speeds, but that the AAP was more effective. There was no long-lasting effect on speeds when the systems were removed. After the trial half of the drivers were willing to keep an ISA system, but more drivers wanted to keep the BEEP-system even though it showed lower satisfaction ratings than the AAP. The results indicate no major differences between the countries despite the workload being perceived to be higher in Hungary than in Spain.     

冲突适应独立于意识：来自行为和ERP的证据

尽管已有研究发现诸如抑制控制和任务转换等认知控制功能独立于意识, 但是对冲突适应是否需要意识的参与目前还存在激烈的争论。为了进一步探讨此问题, 本研究记录了18名被试在完成箭头偏对比掩蔽任务(meta-contrast masking task)时的行为和脑电数据。结果显示, 在有意识和无意识条件下在反应时和额中N2和中顶P3波幅上均表现出了显著的冲突适应效应。这不仅表明冲突控制独立于意识, 而且也表明先前无意识经验对人类信息加工系统的适应性调节作用。本研究对认识认知控制和意识的本质具有重要意义, 也为建构认知控制与意识关系的理论提供了启示。     

特征关联的类别间面孔适应

研究通过系列实验探讨了面孔适应不仅仅发生在形状选择性上, 也能发生在任务相关的特征上有内在关联的两个不同类别的物体间。实验1以带有明显性别倾向的物品图片作为适应刺激, 让被试对男女之间morphing程度不同的图片面孔进行性别辨别, 考察了不同适应刺激呈现时间的类别间面孔适应。结果表明适应刺激呈现时间大于50 ms时均存在类别间面孔适应效应。实验2评估了“性别”这一特征以及适应刺激形式在类别间面孔适应中所起的作用, 结果发现带有性别倾向的物品图片、相应的物品名称和性别文字(“男性”、“女性”) 3种适应刺激类型均能产生类别间适应。实验3通过操纵适应刺激上的注意负荷(高负荷、低负荷和无负荷), 探究了注意对类别间面孔适应的影响。结果表明随着注意负荷的增加, 类别间面孔适应效应减小。3个实验报告了一个新异的类别间适应后效, 证明了适应也能发生于在任务相关特征上有内在关联的两个不同类别的物体间。     

6～12岁儿童Flanker任务下的冲突适应效应

为了探讨6～12岁儿童冲突适应能力的发展,本研究使用经典的Flanker任务,考察了181名一至六年级小学生在冲突任务中的成绩。结果发现,冲突效应在各个年龄段都显著,但是冲突效应大小在不同年龄段之间没有显著差异;对于冲突适应效应,在反应时和准确率上都发现了冲突适应的证据,表现为不一致试次后的冲突效应减小和错误率降低,并且,冲突适应效应的大小在各个年龄段也没有差异。以上结果表明,对于6～12岁左右的小学生,冲突适应效应已经稳定存在,并且,不存在年龄差异。     

冲突适应效应是领域特定的

本研究采用整合的交叉任务范式,通过任务类型的操纵,对冲突适应效应是领域一般的还是领域特定的问题进行了探讨。结果发现当时,在刺激-反应集为4的字母flanker+Simon的整合交叉任务中和刺激-反应集为4的Stroop+Simon的整合交叉任务中,冲突适应效应都是仅存在于任务内,不存在于任务间。说明在控制了重复启动效应且排除了任务之间维度重叠的影响后,两种类型的整合交叉任务都只在任务内观察到冲突适应效应。这表明在控制特征整合的影响后,冲突适应效应是领域特定的,同时说明冲突监测系统不仅是对冲突进行监测,也对冲突的来源进行识别。     

关联规则方法在心理测量中的应用

探讨了当相关系数对变量之间相关程度不易进行度量或者无法度量的情况下,是否可以采用关联规则方法来考察变量之间的相互关系。从理论上分析了关联规则方法在心理测量中应用的可能性,并运用Apriori算法挖掘频繁项集,对来华留学生跨文化适应性数据进行了分析,将关联规则方法分析结果与Pearson相关、Spearman相关结果进行比较,发现当使用关联规则方法进行相互关系分析时,能够更加简易、有效地获得变量间的相关规则。研究结果表明关联规则方法可以获得变量各个水平具体的支持度和置信度,推导出多变量之间的相关规则,并且对于处理非线性的多变量以及多分类变量的相关是非常有用的方法。

Why go the extra mile? A longitudinal study on sojourn goals and their impact on sojourners' adaptation

Although international student mobility has become a ubiquitous phenomenon in many parts of the world, the goals that student sojourners pursue when moving abroad have received little systematic attention in psychological research. Likewise, their effects on psychological outcomes such as sojourners' psychological and sociocultural adaptation abroad have not yet been examined. Hence, the purpose of the present research was twofold: First, we established the parsimonious Sojourn Goals Scale and confirmed its psychometric quality and construct validity. Second, we used a longitudinal sample of student sojourners to investigate the role of sojourn goals for sojourners' sociocultural (i.e., sojourners' social relationships) and psychological (i.e., sojourn satisfaction) adaptation abroad at 3 months into the sojourn. Regression analyses revealed substantial effects of sojourn goals on measures of sociocultural adaptation. Response surface analyses served to examine the interplay of sojourn goals and respective sojourn experiences on sojourn satisfaction. We discuss implications for both psychological and applied research and identify future research needs.
