Upon hearing a novel label, listeners tend to assume that it refers to a novel, rather than a familiar object. While this disambiguation or mutual exclusivity (ME) effect has been robustly shown across development, it is unclear what it involves. Do listeners use their pragmatic and lexical knowledge to exclude the familiar object and thus select…

This study examines the role of the lexicon and grammatical structure building in early grammar. Parent-report data in CDI format from a sample of 1151 German-speaking children between 1;6 and 2;6 and longitudinal spontaneous speech data from 22 children between 1;8 and 2;5 were used. Regression analysis of the parent-report data indicates that…

In a preferential looking paradigm, we studied how children's looking behavior and pupillary response were modulated by the degree of phonological mismatch between the correct label of a target referent and its manipulated form. We manipulated degree of mismatch by introducing one or more featural changes to the target label. Both looking behavior…

Previous research indicates that features of speech during mother-toddler interactions are dependent on the situational context. In this study, we explored language samples of 69 mother-toddler dyads collected during standardized toy play and book-reading situations across two countries, Germany and the United States (US). The results showed that…

Lexical development of bilingual children is influenced by a number of input factors. In the present study, early lexical skills of 25-month old children growing up with Turkish and German were assessed. Parents of 92 children filled out a newly developed list for productive Turkish vocabulary, as well as a vocabulary list for German. A parental…

In this pilot study, we ask whether repeated storybook reading is also beneficial for word learning in children diagnosed with specific language impairment (SLI). We compared 3-year-old German learning children diagnosed with SLI to typically developing children matched on age and socioeconomic status (SES). One week later, children with SLI…

The present article investigates the acquisition of Manner of Articulation (MoA) contrasts in child language production. We analyzed spontaneous longitudinal speech data of four German and six Dutch 1- to 3-year-olds. The data suggest that the acquisition of MoA contrasts is influenced by various co-occurrence constraints at the word level.…

Structural priming is a useful laboratory-based technique for investigating how children respond to temporary changes in the distribution of structures in their input. In the current study we investigated whether increasing the number of object relative clauses (RCs) in German-speaking children's input changes their processing preferences for…

The study investigated the influence of universal and language-specific morpho-syntactic properties (i.e., flexible word order, case) on the acquisition of verb argument structures in German compared with English. To this end, 65 three- to nine-year-old German learning children and adults were asked to act out grammatical ("The sheep…

This study examined lexical-phonological interactions in the first 50 words of a group of monolingual German- and Spanish-speaking children and bilingual German--Spanish children. The phonological characteristics of the earliest target word forms and output patterns of these children were analyzed to determine whether bilingual children select…

Are there individual differences in children's prediction of upcoming linguistic input and what do these differences reflect? Using a variant of the preferential looking paradigm (Golinkoff, Hirsh-Pasek, Cauley, & Gordon, 1987), we found that, upon hearing a sentence like, "The boy eats a big cake," 2-year-olds fixate edible objects…

A randomized control intervention study was conducted to evaluate the effects of the highly structured Heidelberg Parent-Based Language Intervention (HPLI). The outcomes of 43 children (n = 23 intervention, n = 20 control) who had been identified as late talkers during routine developmental check-ups carried out in pediatric practices at the age…

Children's talk about the mind has been scarcely studied in non-English speakers. For this reason, this longitudinal study documents age-related changes in German-speaking children's internal state language. At 24, 30 and 36?months, children were administered general language tests and their internal state vocabulary levels were obtained via…

Using a preferential looking methodology with novel verbs, Gertner, Fisher and Eisengart (2006 ) found that 21-month-old English children seemed to understand the syntactic marking of transitive word order in an abstract, verb-general way. In the current study we tested whether young German children of this same age have this same understanding.…

Presents the Lexical/Semantic Hypothesis, which proposes that early learning is more lexically oriented, and that early word combinations can be explained by more semantically oriented accounts than the Full Competence Hypothesis. The article also replaces the Grammatical Infinitive Hypothesis with the Modal Hypothesis. (32 references) (Author/CK)
