Tapping into the interplay of lexical and number knowledge using fast mapping: A longitudinal eye-tracking study with two-year-olds

Language skills and mathematical competencies are argued to influence each other during development. While a relation between the development of vocabulary size and mathematical skills is already documented in the literature, this study further examines how children’s ability to map a novel word to an unknown object as well as their ability to retain this word from memory may be related to their knowledge of number words. Twenty-five children were tested longitudinally (at 30 and at 36 months of age) using an eye-tracking-based fast mapping task, the Give-a-Number task, and standardized measures of vocabulary. The results reveal that children’s ability to create and retain a mental representation of a novel word was related to number knowledge at 30 months, but not at 36 months while vocabulary size correlated with number knowledge only at 36 months. These results show that even specific mapping processes are initially related to the acquisition of number words and they speak for a parallelism between the development of lexical and number-concept knowledge despite their semantic and syntactic differences.     

Relationship between levels of oral and written language in beginning readers

The validity of a test battery, organized by a theoretical framework of levels of language processing and production, was evaluated at the end of kindergarten and theend of first grade. At the end of kindergarten two levels of oral language, phonemic and lexical, and at the end of first grade three levels of oral language, phonemic, lexical, and text, were correlated with word decoding and reading comprehension. At the end of first grade, the combination of phonemic and lexical skills accounted for more variance in both word decoding and reading comprehension than either phonemic or lexical skills alone. The strength of the relationship between specific levels of oral language and specific component reading skills changed after formal reading instruction was introduced. Functional relationships were found between improvement in phonemic skills or lexical skills and improvement in word decoding. Partial correlations between two levels of oral language with a third partialed out (receptive or expressive task requirements held constant) provided evidence for three semiindependent levels of oral language—phonemic, lexical, and text. Because the battery has concurrent and construct validity, school psychologists can use it to monitor beginning readers in order to prevent reading disabilities due to subtle language dysfunctions.     

Relationship between fine/gross motor skills and language and math development in Colombian Caribbean children: A study in Barranquilla

Literature suggests that motor skills are associated with other areas of development or domains, such as language and math, especially at early ages. These results are mainly based on studies developed in medium-to-high sociocultural contexts. Thus, this study was conducted in a medium-to-low-income area. The aim was to know the 4–5 years old children's motor development (both fine and gross motor skills), and its relation to language and mathematical development. A total of 219 Colombian Caribbean children (105 boys and 114 girls) aged 4 and 5 years participated in this study. Results revealed higher motor skills among girls, although differences by gender were not notable. Positive and significant correlations were found between motor skills and language and mathematical skills, although most of the correlations were weak or moderate. Also, it was observed that fine motor skills were less related to language or mathematical development in comparison with gross motor skills, especially among boys. These results suggest that among Colombian Caribbean children gross motor skills could have a higher influence on the development and acquisition of some language and mathematical skills in comparison with fine motor skills.     

Maternal communicative functions and mind-mindedness at 16 months as predictors of children’s internal and non-internal language at 20 months

The effects of Communicative functions and Mind-Mindedness on children’s language development have been typically investigated in separate studies. The present longitudinal research was therefore designed to yield new insight into the simultaneous impact of these two dimensions of maternal responsiveness on the acquisition of expressive language skills in a sample of 25 mother-child dyads. The frequencies of five communicative functions (Tutorial, Didactic, Conversational, Control and Asynchronous) and two types of mind-related comments (attuned vs. non-attuned) were assessed from a 15-min play session at 16 months. Children’s expressive language was examined at both 16 months (number of word types and tokens produced, and number of words attributed to the child in the Questionnaire for Communication and Early Language development) and 20 months (number of internal and non-internal words attributed to the child in the Italian version of the Mac Arthur-Bates Communicative Development Inventory). The main finding was that mothers’ use of attuned mind-related comments at 16 months predicted internal state language at 20 months, above and beyond the effects of CFs and children’s linguistic ability at 16 months; in addition, mothers’ Tutorial function at 16 months marginally predicted non-internal state language at 20 months, after controlling for MM and children’s linguistic ability at 16 months. These results suggest that different expressions of maternal responsiveness influence distinct aspects of children’s expressive language in the second year of life, although the effects of MM appear to be more robust.     

Emotion Situation Knowledge and Autobiographical Memory in Chinese,Immigrant Chinese,and European American 3-Year-Olds

This study examined the influence of children's emotion situation knowledge (EK) on their autobiographical memory ability at both group and individual levels. Native Chinese, Chinese immigrant, and European American 3-year-old children participated (N = 189). During a home visit, children recounted 2 personal memories of recent, 1-time events with a researcher. Their EK was assessed in a production task (children described situations likely to provoke happy, sad, fearful, or angry emotions) and a judgment task (children judged what emotions story characters were most likely to feel in various situations). European American children had higher EK scores and remembered more details of the past events than their Chinese peers, independent of the influences of age and language skills. EK had the strongest influence on memory reports and mediated the effects of other individual (age, language skills) and group factors (culture, gender). Findings are discussed in light of EK as an important mechanism for the development of autobiographical memory.     

学龄期普通话特异性语言损伤儿童体习得——来自词汇体和语法体组合加工的证据

采用自定步速阅读范式，探讨了7~10岁普通话特异性语言损伤儿童对词汇体和语法体组合语义一致和不一致情况的加工表现。被试分为特异性语言损伤儿童，实龄匹配儿童和语言能力匹配儿童三组，结果表明7~10岁的特异性语言损伤儿童与年幼的语言能力匹配组儿童一样，词汇体和语法体一致条件下的加工快于不一致条件，两组儿童的表现均符合词汇体假设；与此不同，实龄匹配儿童的加工速度整体均快于以上两组儿童，且词汇体和语法体一致与不一致条件下的加工速度无显著差异。上述结果表明，普通话7~10岁特异性语言损伤儿童对词汇体和语法体组合合法性的习得仍不成熟，语法体的加工仍受词汇体影响，处于语法体能力发展的早期阶段。     

注意和记忆对孤独症儿童词汇发展滞后的影响

孤独症语言障碍的表现之一是词汇发展滞后, 可能与其注意和记忆损伤有关。当前研究结果表明, 孤独症儿童在学习词汇时难以利用社会注意提供的有效信息, 且其注意易受到无关刺激干扰, 这可能导致其形成的物体-词汇的联结不稳定, 影响其进一步将这种联结整合到心理词典并保存在记忆中。未来研究应探究联合注意影响孤独症儿童词汇学习的发展轨迹和机制, 儿童的词汇知识对其词汇记忆的影响, 并关注自然场景中孤独症儿童的词汇学习过程和个体差异。     

Do early lexical skills predict language outcome at 3 years? A longitudinal study of French-speaking children

Early language development is considered critical for children’s adjustment in school, for social adaptation and for later educational achievement. Despite the role of children’s receptive skills as a foundation for later productive word use, receptive language skills have received surprisingly little attention. The present research extends recent work on the prediction of preschool language skills by exploring whether a decontextualized measure of lexical comprehension can account for unique variance in preschool language skills above and beyond parent report and how early such a prediction can be made. For this purpose, 65 French-speaking children have been tested at 16, 22, 29 and 36 months.The results of the current study suggest that up to the age of two, although parent reports of lexical comprehension and/or production account for a portion of variance in later receptive, productive or general language outcome, they have less predictive validity than a direct measure of early lexical comprehension. By contrast, after age two, parent reported vocabulary production is the strongest predictor of later language production skills.     

The effects of an early history of otitis media on children's language and literacy skill development

Background. Otitis media (OM) or middle ear infection is a common childhood illness and is most frequent during the crucial first 3 years of life when speech and language categories are being established, which could potentially have a long‐term effect on language and literacy skill development. Aims. The purpose of the current study was to ascertain the effects of a history of OM in early childhood on later language and literacy skill development. Sample. Forty‐three children from Grade 1 and Grade 2, between 6 and 8 years old with an early history of OM and 43 control children, matched for chronological age, gender and socio‐economic status, participated in this study. Methods. Children were tested on multiple measures of phonological awareness, semantic knowledge, narration and reading ability. The performance of children with and without a history of OM was compared on the different measures. Results. There was a general tendency for children with a history of OM to achieve lower scores on phonological awareness skills of alliteration, rhyme and non‐word reading, semantic skills of expressive vocabulary and word definitions and reading than non‐OM children. Conclusion. These findings highlight the potential problems an early history of middle ear infection can have on school‐aged children's later language and literacy development.     

The role of embodied intention in early lexical acquisition

We examine the influence of inferring interlocutors' referential intentions from their body movements at the early stage of lexical acquisition. By testing human participants and comparing their performances in different learning conditions, we find that those embodied intentions facilitate both word discovery and word-meaning association. In light of empirical findings, the main part of this article presents a computational model that can identify the sound patterns of individual words from continuous speech, using nonlinguistic contextual information, and employ body movements as deictic references to discover word-meaning associations. To our knowledge, this work is the first model of word learning that not only learns lexical items from raw multisensory signals to closely resemble infant language development from natural environments, but also explores the computational role of social cognitive skills in lexical acquisition.     

New Word Acquisition in Children: Examining the Contribution of Verbal Short‐term Memory to Lexical and Semantic Levels of Learning

A variety of evidence suggests that human vocabulary acquisition and verbal short‐term ability are related. The aim of this study was to investigate the learning of new lexical and semantic representation in 7 to 12 years old children selected on the basis of their poor working memory capacity. A deep characterization of the short‐term memory (STM) capacities has been carried out through a series of tasks derived from recent STM models tapping STM, language and attentional processes. Participants experienced a three conditions word learning task designed to reflect lexical learning, semantic learning and lexical–semantic learning capacities. Other aspects of the learning such as the learning rate and the word length effect were evaluated. The experimental participants scored more poorly than controls on lexical learning, and this deficit was associated with the serial order STM and the attentional capacities. The current study also highlighted that neither the experimental group nor the control group took advantage in lexical learning of semantic information supplement. Our results suggest that children with verbal STM problems learn a smaller number of new words but present a similar way of learning than children without verbal STM problems.

Uneven Profiles: Language Minority Learners' Word Reading, Vocabulary, and Reading Comprehension Skills

English reading comprehension skill development was examined in a group of 87 native Spanish-speakers developing English literacy skills, followed from fourth through fifth grade. Specifically, the effects of Spanish (L1) and English (L2) oral language and word reading skills on reading comprehension were investigated. The participants showed average word reading skills and below average comprehension skills, influenced by low oral language skills. Structural equation modeling confirmed that L2 oral language skills had a large, significant effect on L2 reading comprehension, whereas students' word-level reading skills, whether in L1 or L2, were not significantly related to English reading comprehension in three of four models fitted. The results converge with findings from studies with monolinguals demonstrating the influence of oral language on reading comprehension outcomes, and extend these findings by showing that, for language minority learners, L2 oral language exerts a stronger influence than word reading in models of L2 reading.

Contributions des aspects idiomatiques et morphologiques du langage à la lecture aux CE1 et CM1

Background and objective

To our knowledge, no research has so far associated idiomatic (or figurative) and morphological aspects of language in children reading and in examining the various skills involved. This study aims to: (1) specify, at two levels of reading ability, the implication of these two dimensions of language in decoding-word identification and comprehension and their possible correlation: idiom comprehension and morphemic skills have in common the need to pay attention to the meaning and play with the different levels of language analysis (literal vs figurative and sublexical vs lexical representations); (2) examine individual performance profiles of children with reading difficulties, in the light of these idiomatic and morphological skills.

The relationship between phonological skills and word decoding

Word decoding ability is a critical factor in reading performance. In the present study, we examined the relationship between word decoding ability and three different phonological skills; phonemic awareness, verbal short-term memory (V-STM), and rapid automatic naming (RAN) in 1007 Scandinavian third- and fifth-graders. In the first part of the study, we sought to investigate the influence of the three phonological skills on word decoding ability. Using multiple regression analysis, our result clearly demonstrated that phonemic awareness was the most powerful phonological skill explaining variance in word decoding ability among average decoders. Among children with poor decoding skills, however, RAN was the most important factor in Grade 3, whereas V-STM was the main contributor to decoding ability among children in Grade 5. In the second part of the research, we examined the relationship between poor phonological skills and word decoding ability. Interestingly, our result revealed that approximately one half of the children with phonological difficulties, still performed within the average range with regard to word decoding ability. However, our analyses confirmed earlier research concerning the severe word decoding difficulties children with both poor phonemic awareness and restricted V-STM, experience.     

儿童早期词汇获得的跨语言/文化研究

婴儿词汇学习是国际语言发展研究的前沿领域, 但大多数研究都是以英语婴儿为研究对象。目前国内关于汉语婴儿早期语言发展研究处于起步阶段。由于汉语在词法、句法等方面具有明显的特殊性, 另外, 成人“言语输入”的语用习惯以及非言语线索都会影响婴儿早期词汇学习, 使得不同语言文化下的婴儿呈现不同的单词学习模式。本项目力图从跨语言视角考察汉语和英语婴儿的早期单词学习(包括单词的理解和产生)以及促进婴儿语言发展的成人言语和非言语输入特征。研究将综合采用实验室实验、半结构化实验室观察和量表测量等研究方法, 利用新的研究技术(如习惯化和IPLP), 从多个角度探索婴儿词汇发展, 以及不同语言文化和个体环境对婴儿早期词汇学习的影响, 揭示词汇获得的跨语言一致性和特异性。研究结果有望对儿童的语言学习提供启示。     

Morphological Knowledge in Children with Dyslexia

The phonological skills are not the only linguistic abilities which are observed to have some influence on reading achievement in dyslexics. In addition to phonological skills, morphological skills should be also taken in consideration. The aim of this study is to extend investigation the linguistic abilities of children with dyslexia to the morphological level through examination whether there is a lack of morphological knowledge in children with dyslexia for Bosnian language with transparent orthography. Testing sample included 45 children with dyslexia that are compared with chronological age and reading level controls. The dyslexic children performed significantly worse than same age controls on all forms of word and the most complex word formation tasks. Based on the examination of standardized discriminant function coefficients the variable with the highest weight in defining the first discriminant function was the suffixal formation, declination of personal pronouns, changing gender of adjectives with regard to the gender of a noun, and changing of gender of cardinal numbers with regard to the gender of a noun best differentiates groups. Results of multivariate analyses of variance also showed that chronological age and reading level groups outperformed dyslexics on all these tasks. Our results suggest that dyslexics have problems with morphological knowledge which indicate that certain actions regarding the development of morphological abilities in dyslexics should be taken in the elementary grades.     

Gender and lexical access in Bulgarian

Two procedures were used to explore the effects of semantic and grammatical gender on the recognition and processing of Bulgarian nouns, in relation to other factors that are known to affect lexical access. This study in a three-gender language was modeled on previous work in Italian, a two-gender language (Bates, Devescovi, Pizzamiglio, D'Amico, & Hernandez, 1995). Words were presented auditorily in randomized lists in two tasks: (1) repeat the word as quickly as possible and (2) determine the grammatical gender of the noun as soon as possible and indicate the decision by pressing a button. Reaction times in both tasks were influenced by phonological factors, word frequency, and irregularity of gender marking, but semantic and grammatical gender affected only gender monitoring. The significant contribution of semantic gender to processing in Bulgarian contrasts with previous findings for Italian. Also, we obtained an interaction between sex of the subject and noun gender, reflecting a bias toward one's own grammatical gender "counterpart" (especially for females). Reanalysis of the prior study in Italian showed a similar interaction but confirmed no effects of the semantic gender of the noun, suggesting that these two natural gender effects can dissociate. Possible reasons for cross-linguistic differences are discussed, with implications for comparative studies of gender and lexical access.     

Early precursors and enabling skills of reading acquisition

Research on early linguistic precursors and enabling skills of reading acquisition among young children is reviewed. Language development starts early in infancy when the child learns to categorize the speech sounds according to the pattern typical of the mother tongue. Equipped with these sound categories the child is ready to learn to segment words from the sound stream and to understand and to use words. The precise phonological representation of words will facilitate the important development of phonological awareness, a basic prerequisite for reading acquisition. This paper reviews some of my longitudinal research and training studies indicating the causal direction of the relation between phonological awareness and reading and includes some ongoing studies, where gender differences, socio‐economic factors, dose‐response‐effects and motivational factors are explored. Preventive and remedial implications of the findings are pointed out. Finally, the complexity of the causal relationships between different aspects of early language development, including genetic influences and later reading is pointed out.
