What's different in second-language processing? Evidence from event-related brain potentials

German sentences which were either correct, contained a selectional restriction violation, or a word category violation were presented auditorily to 16 native speakers of German (L1 group) and to 16 native speakers of Russian, who had learned German after the age of 10 (L2 group). Semantic violations elicited an N400 effect for both groups, but with a reduced amplitude and a longer peak latency in the L2 group. Compared to correct sentences, sentences with a phrase structure violation elicited an early anterior negativity followed by a broad centro-parietal positivity in native speakers. By contrast, there was no differential modulation of the early anterior negativity in the L2 group. A late positivity was also elicited in the second language learners, but it was slightly delayed compared to that shown by native speakers. This pattern is discussed in terms of different degrees of automaticity with respect to the subprocesses involved in sentence comprehension.     

Test of a potential link between analytic and nonanalytic category learning and automatic, effortful processing

The link between automatic and effortful processing and nonanalytic and analytic category learning was evaluated in a sample of 29 college undergraduates using declarative memory, semantic category search, and pseudoword categorization tasks. Automatic and effortful processing measures were hypothesized to be associated with nonanalytic and analytic categorization, respectively. Results suggested that contrary to prediction strong criterion-attribute (analytic) responding on the pseudoword categorization task was associated with strong automatic, implicit memory encoding of frequency-of-occurrence information. Data are discussed in terms of the possibility that criterion-attribute category knowledge, once established, may be expressed with few attentional resources. The data indicate that attention resource requirements, even for the same stimuli and task, vary depending on the category rule system utilized. Also, the automaticity emerging from familiarity with analytic category exemplars is very different from the automaticity arising from extensive practice on a semantic category search task. The data do not support any simple mapping of analytic and nonanalytic forms of category learning onto the automatic and effortful processing dichotomy and challenge simple models of brain asymmetries for such procedures.     

What if they are right? Network approval,expectations, and relationship maintenance behaviors

This study drew on uncertainty reduction and decision‐making theories to investigate how perceptions of approval of romantic relationships from family and friends can influence romantic partners' dynamics. Using a dyadic approach, the authors examined whether expectations of a partner's behavior in the relationship mediated the associations between perceived social network approval and relationship maintenance behaviors in a sample of 137 couples. The actor–partner interdependence mediation model (APIMeM) was applied. Results showed that women's and men's perceptions of approval from their own and their partner's network were associated with their own level of expectations of their partner's behaviors. In turn, women's and men's expectations were associated with their own and their partner's maintenance behaviors.     

语境预测性对阅读中字词加工过程的影响：眼动证据

研究包含3项实验,通过观察语境预测性与目标词汇的整词词频、词内汉字字频间交互作用,以探讨阅读中语境预测性如何影响中文词汇加工问题。研究以双字词为例,实验1操控目标词汇的语境预测性与整词词频,结果发现,语境预测性与整词词频交互作用不显著。实验2操控目标词汇的语境预测性与首字字频,结果发现,语境预测性与首字字频交互作用不显著。实验1和实验2的贝叶斯分析都倾向于支持交互作用不存在假设。实验3操控目标词汇的语境预测性与尾字字频,结果发现,语境预测性与尾字字频交互影响首次注视时间、凝视时间、总注视时间和再注视概率。由此可知,语境预测性与整词词频、首字字频变量相对独立地影响词汇加工;语境预测性直接影响词内汉字(尾字)的加工过程。     

人声加工的神经机制

人声是人类听觉环境中最熟知和重要的声音, 传递着大量社会相关信息。与视觉人脸加工类似, 大脑对人声也有着特异性加工。研究者使用电生理、脑成像等手段找到了对人声有特异性反应的脑区, 即颞叶人声加工区(TVA), 并发现非人类动物也有类似的特异性加工区域。人声加工主要涉及言语、情绪和身份信息的加工, 分别对应于三条既相互独立又相互作用的神经通路。研究者提出了双通路模型、多阶段模型和整合模型分别对人声的言语、情绪和身份加工进行解释。未来研究需要进一步讨论人声加工的特异性能否由特定声学特征的选择性加工来解释, 并深入探究特殊人群(如自闭症和精神分裂症患者)的人声加工的神经机制。

Re-Examining the Effect of Top-Down Linguistic Information on Speaker-Voice Discrimination

The current study replicated and extended the results from a study conducted by Narayan, Mak, and Bialystok (2017) that found effects of top-down linguistic information on a speaker discrimination task by examining four conditions: rhymes (day-bay), compounds (day-dream), reverse compounds (dream-day), and unrelated words (day-bee). The original study found that participants were more likely to judge two words to be spoken by the same speaker if the words cohered lexically (created lexical compounds such as day-dream) or were phonologically related (rhymes, such as day-bay), but their study contained two limitations: (a) Same- and different-speaker trials were analyzed separately, which obscures effects of response bias, and (b) cross-gender pairs were used in the different-speaker trials, potentially inflating performance. The current study addresses these limitations by including only within-gender trials and by examining sensitivity and bias using signal detection theory. Our results not only provide support of the original study but also provide clear evidence that listeners are biased to judge two words as being produced by the same person when they share either phonological information (rhymes) or lexical-semantic coherence (compounds). Thus, the current study provides an important modified replication of previous research.     

Psychometric properties and reference data for Danish versions of Free and Cued Selective Reminding Test,Category Cued Memory Test and Logical Memory

Memory assessment is a key element in neuropsychological testing. Gold standard evaluation is based on updated normative data, but in many small countries (e.g. in Scandinavia) such data are sparse. In Denmark, reference data exist for non‐verbal memory tests and list‐learning tests but there is no normative data for memory tests which capture narrative recall and cued recall. In a nation‐wide study, Free and Cued Selective Reminding Test (FCSRT ), WMS ‐III Logical Memory (LM ) and a newly developed test Category Cued Memory Test (CCMT ‐48) were applied in 131 cognitively intact persons (aged 60–96 years). Regression‐based reference data for Danish versions of FCSRT , CCMT ‐48 and LM adjusted for age, education and gender are provided. Gender and age‐group had a significant impact on the expected scores, whereas the effect of education had a limited effect on expected scores. Test performances were significantly correlated in the range 0.21–0.51. Based on these findings and previous results it may be relevant to assess both free recall, cued recall and recognition to tap the earliest changes associated with neurodegeneration, and this study therefore provides an important supplement to existing Danish normative data. Future studies should investigate the discriminative validity of the tests and the clinical utility of the presented reference data.     

整字和部件的语义关系对汉字认知的影响

等级汉字是指由小汉字组成的大汉字。依据Navon的复合刺激范式,实验1选取“生物和非生物范畴”的汉字构建等级汉字,探索语义范畴是否一致对刺激认知的影响。实验2选取“意义相反或无关”的汉字组成等级汉字,采用真假字判断任务探索语义关系对刺激加工的影响。实验结果发现,等级汉字加工受大小汉字语义范畴关系和语义关系的影响,同时,任务类型影响汉字认知。
