双语言语产生中的词汇提取机制 总被引:4,自引:0,他引:4
文章主要介绍了双语言语产生中词汇提取机制的两种理论:非特定语言提取的理论和特定语言提取的理论。重点围绕着双语言语产生中词汇提取的一个关键问题,即非目标语言的词汇是否对目标语言的词汇提取形成竞争或者干扰详细地论述了二者的理论分歧,非特定语言提取的理论认为非目标语言的词汇会对目标语言的词汇提取形成竞争,而特定语言提取的理论认为不会形成竞争。文章最后介绍了双语言语产生中词汇提取机制的最新研究趋势,表明了非特定语言提取的理论和特定语言提取的理论逐步走向融和 相似文献

It is not unusual that people have to write in an environment where background speech is present. Background speech can vary in both speech intelligibility and location of the sound source. Earlier research has shown disruptive effects of background speech on writing performance. To expand and reinforce this knowledge, the present study investigated the role of number of voices and sound source location in the relation between background speech and writing performance. Participants wrote texts in quiet or in background speech consisting of one or seven voices talking simultaneously located in front of or behind them. Overall, one voice was more disruptive than seven voices talking simultaneously. Self‐reports showed that sound from the front was more disruptive compared with sound from behind. Results are in line with theory of interference‐by‐process, attentional capture, and the cross‐modal theory of attention. The relevance of the results for open‐office environments is discussed. 相似文献

Previous studies reveal an association between particular features of parental language input and advances in children's language learning. However, it is not known whether parent coaching aimed to enhance specific input components would (a) successfully increase these components in parents' language input and (b) result in concurrent increases in children's language development. The present randomized controlled trial assigned families of typically developing 6‐month‐old infants to Intervention (parent coaching) and Control (no coaching) groups. Families were equivalent on socioeconomic status, infants' gender, and infants' age. Parent coaching took place when infants were 6 and 10 months of age, and included quantitative and qualitative linguistic feedback on the amount of child‐directed speech, back‐and‐forth interactions, and parentese speech style. These variables were derived from each family's first‐person LENA recordings at home. Input variables and infant language were measured at 6, 10, and 14 months. Parent coaching significantly enhanced language input as measured by two social interaction variables: percentage of speech directed to the child and percentage of parentese speech. These two variables were correlated, and were both related to growth in infant babbling between 6 and 14 months. Intervention infants showed greater growth in babbling than Control infants. Furthermore, at 14 months, Intervention infants produced significantly more words than Control infants, as indicated by LENA recordings and parent report via the MacArthur‐Bates Communicative Developmental Inventory. Together, these results indicate that parent coaching can enrich specific aspects of parental language input, and can immediately and positively impact child language outcomes.

Here we report, for the first time, a relationship between sensitivity to amplitude envelope rise time in infants and their later vocabulary development. Recent research in auditory neuroscience has revealed that amplitude envelope rise time plays a mechanistic role in speech encoding. Accordingly, individual differences in infant discrimination of amplitude envelope rise times could be expected to relate to individual differences in language acquisition. A group of 50 infants taking part in a longitudinal study contributed rise time discrimination thresholds when aged 7 and 10 months, and their vocabulary development was measured at 3 years. Experimental measures of phonological sensitivity were also administered at 3 years. Linear mixed effect models taking rise time sensitivity as the dependent variable, and controlling for non‐verbal IQ, showed significant predictive effects for vocabulary at 3 years, but not for the phonological sensitivity measures. The significant longitudinal relationship between amplitude envelope rise time discrimination and vocabulary development suggests that early rise time discrimination abilities have an impact on speech processing by infants. 相似文献

The term “fresh expressions of church” has been used since 2004 in the Church of England to refer to small contextual churches that start alongside but aim to be different to parish churches. What is characteristic of a fresh expression of church is not its newness, but its ability to pass on and contextualize inherited theology, ecclesiology, tradition, and spiritual experience. The ecclesiology of fresh expressions of church can be summarized as a dialogical‐relational ecclesiology that is focused on a theological centre. There may be around 2,100 of them in the Church of England, both urban and rural. During the past 15 years, the self‐understanding of the Church of England, a traditional state church with its parish structure, has changed. The mother church of the Anglican World Communion claims since 2008 to be a mixed‐economy church: one that supports and recognizes innovative ecclesial spaces (fresh expressions of church) as church, as well as parish churches. It is the goal to have an innovative diversity of churches in a pluralistic society. At the same time, these churches should be recognizable and contextual. It is the concept of the mixed economy that manages a fair cooperation between parochial and fresh expressions of church. In the meantime, the concept of mixed economy is received not only in the UK, but in different national and free churches in continental Europe, the US, South Africa, Canada, and Australia. Lately, the concept has been taken up by the Community of Protestant Churches in Europe (CPCE). 相似文献

Approximately 30% of individuals diagnosed with autism spectrum disorder (ASD) fail to develop vocal communication and, therefore, use some form of augmentative or alternative communication system. The current study replicates and extends previous research on teaching “Who?” and “Which?” mands for information to 3 young children diagnosed with ASD using a speech generating device. Procedures were evaluated using a multiple baseline across participants design. All participants learned to mand for information and, subsequently, used the information to access preferred items. 相似文献

This study explored the temporal contingencies between infant and adult vocalizations as a function of the type of infant vocalization, whether adult caregivers’ vocalizations were infant-directed or other-directed, and the timescale of analysis. We analyzed excerpts taken from day-long home audio recordings that were collected from nineteen 12- to 13-month-old American infants and their caregivers using the LENA system. Three 5-minute sections having high child vocalization rates were identified within each recording and coded by trained researchers. Infant and adult vocalizations were sequenced and defined as contingent if they occurred within 1 s, 2 s, or 5 s of each other. When using 1 s or 2 s definitions of temporal adjacency, infant vocalizations generally predicted subsequent infant-directed adult vocalizations. A reflexive vocalization (i.e. a cry or a laugh) was the strongest predictor. Likewise, within 1–2 s timeframes, infant-directed adult speech generally predicted infant vocalizations with reflexive vocalizations being particularly predictive. Infant vocalizations predicted fewer subsequent other-directed adult vocalizations and were less likely following other-directed adult vocalizations when considering up to 5 s lags. This suggests an understudied communicative role for infants of non-infant-directed adult speech. These results demonstrate the importance of timescale in studying infant-adult interactions, support the communicative significance of reflexive infant vocalizations and other-directed adult speech in addition to more commonly studied vocalization types, and highlight the challenges of determining direction(s) of influence when using only two-event sequences. 相似文献

Based within a self-determination theory framework (SDT: Deci and Ryan, Intrinsic motivation and self-determination in human
behaviour. Plenum Publishing Co., New York, 1985), the present study examined the effects of manipulating social-contextual conditions on the content of individuals’ self-talk.
Seventy student volunteers were randomly assigned to a controlling or autonomy-supportive experimental condition. Participants
were instructed to ‘think-aloud’ throughout a 10-min computerized task during which self-verbalizations were recorded. Audio
recordings were transcribed verbatim, and then analysed using the Linguistic Inquiry and Word Count Program (LIWC; Pennebaker
et al., LIWC2001; Linguistic Inquiry and Word Count (software and manual). Lawrence Erlbaum, Mahwah, NJ, 2001). Inductive content analyses were also conducted. Triangulation of the quantitative and qualitative findings revealed that
in the autonomy-supportive condition, individuals’ self-talk was more informational and less controlling, with participants
using more positive emotional words and assents, and fewer negative emotional words, swear words, and first person references
than in the controlling condition. The findings suggest that social-context can affect cognitive factors such as self-talk
and further support the promotion of autonomy-supportive environments. 相似文献

Although infants begin to encode and track novel words in fluent speech by 7.5 months, their ability to recognize words is somewhat limited at this stage. In particular, when the surface form of a word is altered, by changing the gender or affective prosody of the speaker, infants begin to falter at spoken word recognition. Given that natural speech is replete with variability, only some of which determines the meaning of a word, it remains unclear how infants might ever overcome the effects of surface variability without appealing to meaning. In the current set of experiments, consequences of high and low variability are examined in preverbal infants. The source of variability, vocal affect, is a common property of infant-directed speech with which young learners have to contend. Across a series of four experiments, infants' abilities to recognize repeated encounters of words, as well as to reject similar-sounding words, are investigated in the context of high and low affective variation. Results point to positive consequences of affective variation, both in creating generalizable memory representations for words, but also in establishing phonologically precise memories for words. Conversely, low variability appears to degrade word recognition on both fronts, compromising infants' abilities to generalize across different affective forms of a word and to detect similar-sounding items. Findings are discussed in the context of principles of categorization that may potentiate the early growth of a lexicon. 相似文献
