噪音背景对二语语音感知的影响

日常言语交流常常会遇到各种噪音的干扰。研究表明, 噪音所产生的能量掩蔽和信息掩蔽会给语音感知带来较大影响。在感知地道的二语语音时, 二语者在各种噪音条件下所受干扰通常比母语者更大, 其表现随噪音类型、水平和目标音位特征的不同而变化; 同时, 二语者的感知也存在较大个体差异, 这是多种因素影响的结果。在噪音下感知带有各种外国腔的二语口音时, 母语者的表现差于其对地道母语语音的感知; 二语经历贫乏的二语者则对与自己口音类似的外国腔感知较好, 但二语经历较长的二语者在感知中却表现出较大灵活性。     

工作记忆、语境限制强度和句子长度对二语词汇学习的影响

本研究选取初二、高二、大三三个年龄段的被试,考察在句子阅读过程中,工作记忆容量、语境限制强度和句子长度对第二语言词汇学习的影响。研究结果发现,在句子阅读条件下,工作记忆容量是影响第二语言词汇学习的重要因素,高工作记忆容量促进了第二语言词汇的学习;在中等和长句子的条件下,语境的限制性越强,词汇学习的成绩越好;相比初二年龄组被试,高二和大三年龄组被试,在低语境限制性的情况下,阅读的句子越长,第二语言词汇学习效果越差。研究结果说明,个体工作记忆的容量,以及阅读材料等变量,都是影响自然阅读条件下二语词汇学习的重要因素。     

Two Second‐Personal Conceptions of the Dignity of Persons

In spite of the burgeoning philosophical literature on human dignity, Stephen Darwall's second‐personal account of the dignity of persons has not received the attention it deserves. This article investigates Darwall's account and argues that it faces a dilemma, for it succumbs either to a problem of antecedence or to the wrong kind of reasons problem. But this need not mean one should reject a second‐personal account. Instead, I argue that an alternative second‐personal conception, one I will call relational, promises to solve the dilemma by avoiding both the problem of antecedence and the wrong kind of reasons problem. More generally, distinguishing these two second‐personal conceptions of the dignity of persons is important to enrich the available philosophical accounts of human dignity.     

Inhibitory control and the speech patterns of second language users

Inhibitory control (IC), an ability to suppress irrelevant and/or conflicting information, has been found to underlie performance on a variety of cognitive tasks, including bilingual language processing. This study examines the relationship between IC and the speech patterns of second language (L2) users from the perspective of individual differences. While the majority of studies have supported the role of IC in bilingual language processing using single‐word production paradigms, this work looks at inhibitory processes in the context of extended speech, with a particular emphasis on disfluencies. We hypothesized that the speech of individuals with poorer IC would be characterized by reduced fluency. A series of regression analyses, in which we controlled for age and L2 proficiency, revealed that IC (in terms of accuracy on the Stroop task) could reliably predict the occurrence of reformulations and the frequency and duration of silent pauses in L2 speech. No statistically significant relationship was found between IC and other L2 spoken output measures, such as repetitions, filled pauses, and performance errors. Conclusions focus on IC as one out of a number of cognitive functions in the service of spoken language production. A more qualitative approach towards the question of whether L2 speakers rely on IC is advocated.     

内隐学习在第二语言语音学习中的作用

本研究以大学生为被试,用符合德语读音规则的人造无意义单词(含4~5个音素)为刺激材料,采用强分离程序———匹配和编辑,并增设时间变量,比较了在先匹配后编辑,先编辑后匹配,只匹配,只编辑4种不同内隐、外显学习方式下被试对语音规则的掌握。结果表明,语音学习中存在内隐学习的优势效应,内隐与外显结合的学习方式最好。此外,实验证实了语音的内隐学习也存在长时效应。     

Second language vocabulary level is related to benefits for second language listening comprehension under lower reverberation time conditions

The acoustic qualities of a room can have a deleterious effect on the quality of speech signals. The acoustic measurement of reverberation time (RT) has shown to impact second language (L2) speech comprehension positively when lower due to release from spectral and temporal masking effects as well as top-down processing factors. This auralization experiment investigated the benefits of better L2 vocabulary and executive function (updating) skills during L2 listening comprehension tests under shorter versus longer RT conditions (0.3 and 0.9?s). 57 bilingual university students undertook L2 vocabulary, number updating and L2 listening comprehension tests. After splitting groups into high/low vocabulary and updating groups, a mixed ANOVA was conducted. The high number updating group showed no significant differences or interactions in L2 listening comprehension than the lower number updating group across RT conditions. The high vocabulary group had 22% better L2 listening comprehension than the low vocabulary group in long RT, and 9% better in short RT. A significant benefit in L2 listening comprehension due to release from reverberation was only evident in the high vocabulary group. Results indicate that the benefit of good room acoustics for listening comprehension is greatest for those with better language (vocabulary) ability.     

语境和构词法线索对外国学生汉语词义猜测的作用

要求学习汉语的欧美和日本留学生对三种条件下(只有词没有语境、只有语境没有词、既有词也有语境)的语义半透明的双音复合词进行猜测, 考察语境和构词法线索在欧美和日本留学生汉语生词猜测中的作用。结果显示：在猜测词义中语境和构词法线索分别都能提供一定的信息, 但同时提供两种信息能得到更好的猜测; 语境和构词法线索在生词猜测过程中所起的作用不同, 语境能提供更多句法上的信息, 构词法能提供更多语义上的信息; 目标词的结构方式对生词猜测产生影响, 与动宾式生词相比, 偏正式生词的猜测较为容易且构词法线索在其中的作用较大; 母语文字背景可能影响词义猜测的效果, 日本留学生对于构词法、语境线索以及两者的整合都比欧美留学生好。     

汉语作为第二语言的越南大学生汉字部件意识的发展*

以226名将汉语作为第二语言的越南大学一到四年级学生为研究对象,以低频独体字、部件熟悉假字和部件不熟悉假字为材料,采用延迟书写任务,考察了不同年级的越南大学生汉字部件意识的发展及其影响因素。结果发现：（1）学习3个月汉语的大一学生能以部件作为汉字加工单元,其延迟书写部件熟悉假字显著好于低频独体字,并与高年级学生没有差异,说明越南大学生很早就发展出了汉字部件意识;（2）不同年级大学生书写部件不熟悉假字的成绩都显著低于部件熟悉假字,也低于低频独体字,表明部件构字能力是越南大学生汉字书写的重要影响因素。（3）越南大一学生的汉字书写成绩受到汉字结构的影响,左右结构优于上下结构,但其他年级的成绩不受汉字结构的影响。

语音训练对幼儿英语语音意识和字母知识的促进

语音意识是影响英语阅读能力的关键因素。本研究结合语音教学法的思想,采用自编的教学材料和语音游戏,通过字母故事和语音训练游戏,训练儿童的语音意识。研究者在北京市一所普通幼儿园选取了无英语学习经验的3岁左右中国幼儿63名,随机分为实验组和控制组,经过8周的语音教学实验,发现接受语音教学的实验组儿童在音节意识、音韵意识、音素意识和字母识别等方面较接受普通英语教学的控制组都有显著提高。结果表明早期有针对性的语音训练可能能够更快地提高幼儿的语音意识。
