In addition to being secondary, over-inclusive and crude indicators of cerebral activity, psychometric tests are subject to economic incentives to “re-norm” traditional methods under the pretense of “ensuring” contemporary representations that are sanctioned by regulating organizations dominated by agendas of control over the interpretations of clinicians. The validity of neuropsychological tests is essential for their perspicacious application and interpretations. We measured the quantitative electroen-cephalographic profiles and calculated s-LORETA (standardized Low Resolution Electromagnetic Tomography) profiles in real time for normal men and women while they engaged in both traditional and novel neuropsychological tests that were employed to infer localized brain injury. Conspicuous alterations in source current density within specific frequency bands occurred within various regions of the right prefrontal region during performance of the Category, Design Fluency and Conditioned Spatial Association Test, the prefrontal medial surface during Toe Graphaesthesia, the caudal medial surface during Toe Gnosis, the left temporal region during Speech-Sounds, and within the right retrosplenial-parahippocampal region for Seashore Rhythms. Results supported the well established regional associations with the classic neuropsychological tests, verified the cerebral localization with more recent procedures, and emphasized the utility of modern real-time, direct cerebral imaging procedures.展开更多

本研究采用自由联想法及单类内隐联想测验(Single Category Implicit Association Test,SC-IAT)分别测量了大学生对愤青群体的外显及内隐态度。使用自编自由联想问卷得出当代大学生对愤青群体的外显态度,采用单类内隐联想测验(SC-IAT),...本研究采用自由联想法及单类内隐联想测验(Single Category Implicit Association Test,SC-IAT)分别测量了大学生对愤青群体的外显及内隐态度。使用自编自由联想问卷得出当代大学生对愤青群体的外显态度,采用单类内隐联想测验(SC-IAT),测量大学生对愤青群体的内隐态度。结果发现:(1)当代大学生对待愤青群体的态度,在外显和内隐层面上是不一致的,在外显层面倾向于认同;在内隐层面倾向于不认同。(2)男性与女性在对待愤青群体的内隐态度上存在显著性差异:男性的内隐态度倾向于认同,女性则不认同。展开更多

文摘汉语数量形容词(多和少)可以充当谓语,用以说明主语的数量范畴。同时,此类结构通常会产生关联效应(association effect)解读,即主语与话题成分产生关联,如"说到教过的学生,张三很多/少"。在动态句法(Dynamic Syntax Kempson et al.2001;Cann et al.2005)理论框架下,本文认为,此关联效应是一个句法、语义和语用的互动现象:(1)数量形容词内涵的词汇信息要求其说明描述的对象具有集合性质;(2)在语句解析过程中,计算规则将匹配形容词及其描述对象的算子信息,并进而决定语句的合法性;(3)在线性序列和语境信息的作用下,可以有效解析此类结构产生的歧义现象。
