Neural coding of formant-exaggerated speech in the infant brain

Speech scientists have long proposed that formant exaggeration in infant-directed speech plays an important role in language acquisition. This event-related potential (ERP) study investigated neural coding of formant-exaggerated speech in 6-12-month-old infants. Two synthetic /i/ vowels were presented in alternating blocks to test the effects of formant exaggeration. ERP waveform analysis showed significantly enhanced N250 for formant exaggeration, which was more prominent in the right hemisphere than the left. Time-frequency analysis indicated increased neural synchronization for processing formant-exaggerated speech in the delta band at frontal-central-parietal electrode sites as well as in the theta band at frontal-central sites. Minimum norm estimates further revealed a bilateral temporal-parietal-frontal neural network in the infant brain sensitive to formant exaggeration. Collectively, these results provide the first evidence that formant expansion in infant-directed speech enhances neural activities for phonetic encoding and language learning.     

Savouring and perceived job performance in positive psychology: Moderating role of positive affectivity

Building on the research in positive psychology, the current study examines the impact of employee savouring on building perceived job performance and tested the extent to which an individual positive affectivity moderated the relationship of savouring and job performance. Using survey responses from 357 salespeople in six Taiwanese insurance companies, the results of hierarchical regression analyses show that savouring is positively related to perceived job performance. In addition, the relationship between savouring and perceived job performance was moderated by employees' positive affectivity. The implications of these results and the limitations of the research are discussed.     

测试效应：致力于有效学习的基础研究

学习与记忆研究领域关于测试效应的研究重新审视了“测试”的作用。测试除了是衡量学习程度的工具,它对学习的作用相当于甚至大于同等时间的“学习”;相对于重复学习,测试使学习者对学习的元认知判断更准确;学习过程中的自我测试虽然可能延缓学习的进程,但却可促进有效学习。课堂小测或培养学生自我测试策略有助于其知识更好地保持于长时记忆中。     

回避性依恋和注意偏向：刺激普遍性与刺激特定性

采用工作记忆算式-词对广度任务,通过87名大学生探索依恋回避倾向性与注意的关系。研究发现：依恋回避与三类词的工作记忆成绩呈负相关;工作记忆广度类型、词类型主效应显著;工作记忆广度类型与词类型交互作用显著。结果表明：回避性依恋者具有回避性注意偏向;回避性注意偏向既有刺激普遍性,又有刺激特定性,依恋性刺激比中性刺激更容易在信息加工早期被防御性地排除;回避性注意偏向具有调节情绪的功能性价值。为去激活策略情绪调节观提供了跨文化研究证据。     

大学生自我同一性、时间管理倾向和网络成瘾的相关关系研究

目的探讨大学生自我同一性、时间管理倾向与网络成瘾之间的相关,分析前两者是否能够显著地影响和预测后者。方法采用《中文网络成瘾量表》、《自我同一性地位量表》、《大学生时间管理倾向》对当前在校大学生自我同一性发展、时间管理倾向、网络成瘾状况进行调查研究。结果自我同一性三个维度与网络成瘾均成显著负相关(p<0.01);时间管理倾向各维度得分及总分与网络成瘾呈显著的负相关(p<0.01);自我同一性中的三个维度和时间管理倾向三个维度及总分均有非常显著的正相关(p<0.01)。通过分层回归分析发现,自我同一性对网络成瘾的影响是受时间管理倾向的中介作用。结论自我同一性与时间管理倾向对网络成瘾有一定的预测力,而且自我同一性会通过时间管理间接影响网络成瘾。

Unilateral implicit motor learning deficit in developmental dyslexia

It has been suggested that developmental dyslexia involves various literacy, sensory, motor skill, and processing speed deficits. Some recent studies have shown that individuals with developmental dyslexia exhibit implicit motor learning deficits, which may be related to cerebellar functioning. However, previous studies on implicit motor learning in developmental dyslexics have produced conflicting results. Findings from cerebellar lesion patients have shown that patients' implicit motor learning performance varied when different hands were used to complete tasks. This suggests that dyslexia may have different effects on implicit motor learning between the two hands if cerebellar dysfunction is involved. To specify this question, we used a one-handed version of a serial reaction time task to compare the performance of 27 Chinese children with developmental dyslexics with another 27 age-matched children without reading difficulties. All the subjects were students from two primary schools, Grades 4 to 6. The results showed that children with developmental dyslexic responded more slowly than nondyslexic children, and exhibited no implicit motor learning in the condition of left-hand response. In contrast, there was no significant difference in reaction time between two groups of children when they used the right hand to respond. This finding indicates that children with developmental dyslexia exhibited normal motor skill and implicit motor learning ability provided the right hand was used. Taken together, these results suggested that Chinese children with developmental dyslexia exhibit unilateral deficits in motor skill and implicit motor learning in the left hand. Our findings lend partial support to the cerebellar deficit theory of developmental dyslexia.     

Mystical Experience Among Tibetan Buddhists: The Common Core Thesis Revisited

In the study of mysticism the debate has centered on whether a universal experiential core exists regardless of religious interpretation. The current investigation combines Jamesian empiricist and social constructivist perspectives to argue that stable experiential facets load variously on factors to construct local interpretations. Local interpretations reflect a family resemblance—a mystical common core experienced across cultures. Results of confirmatory factor analyses, based on data from 240 Tibetan Buddhist adults, suggest statistical model fit and superiority for the three‐factor model compared to the unidimensional model. Pure experience can be distinguished explicitly from its context‐specific hermeneutical construal.
