Vocabulary knowledge is one of the most important elements of reading comprehension. Text coverage is the proportion of known words in a given text. We hypothesize that text comprehension increases exponentially with text coverage due to network effects and activation of prior knowledge. In addition, the lexical threshold hypothesis states that…

Sleep right after studying new material is more conducive to memory than a period of wakefulness. Another way to counteract forgetting is to practice retrieval: taking a test strengthens memory more effectively than restudying the material. The current work aims at investigating the interaction between sleep and testing by asking if testing adds…

Explicit vocabulary learning is a burden for most of the students. But vocabulary is the basis of each language, and not all words can be acquired incidentally through context or reading. Especially for content and language integrated learning in L2 it is important to offer lots of support for learning a large number of terms in order to avoid…

Children in early childhood education and care (ECEC) spend a considerable amount of time interacting with their peers. However, open questions remain on whether and how children influence their peers' language development. The present study examined effects of peers' German receptive vocabulary (n = 1,871) on individual children's (n = 431)…

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…

Research Findings: Are family literacy activities linked to gains in preschool-aged dual language learners' (DLLs') societal language vocabulary? To understand connections between literacy activities and vocabulary, we separately considered literacy activities in the respective heritage language and in the societal language, German, and accounted…

Metalinguistic awareness (MLA) is a predictor of adult foreign language (FL) learning in instructed settings. Following Bialystok and Ryan (1985) two-component model of MLA, we distinguish ML analysis as the ability to compare and select language items from ML control as the ability to detect and manipulate rule-based linguistic patterns. So far,…

Heritage language (HL) speakers seem to diverge from monolingual speakers in the acquisition of syntax-discourse interface phenomena. However, most of the studies reporting this finding do not make any distinction between different types of syntax-discourse interface structures. Therefore, it is an open question whether these structures are…

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…

There is a need to provide bilingual assessments and reference data to identify those who struggle to acquire their heritage language (L1) or the language spoken in the country of residence (L2). However, bilingual assessments and data are still sparse. Therefore, the aim was to use a tablet application to screen receptive vocabulary in different…

Shared-book reading is a well-established intervention to foster vocabulary development. Factors influencing its effectiveness are, however, less well studied, particularly with regard to story-delivery. We contrasted a read-aloud with a free storytelling approach and tested effects on vocabulary learning. In the first study, 83 preschoolers aged…

Theories and research in embodied cognition postulate that cognition grounded in action enjoys a processing advantage. Extending this theory to the study of how fine motor skills (FMS) link to vocabulary development in preschool children, the authors investigated FMS and vocabulary in 76 preschoolers. Building on previous research, they…

Phonological awareness, rapid automatized naming (RAN), letter knowledge, and oral language are all significant predictors of successful literacy acquisition in several languages. However, their relative importance is less clear and depends on language characteristics, the specific aspect of literacy assessed, and the phase of literacy…

Children develop linguistic competencies during interactions with more knowledgeable others. Consequently, one way to support this development is by enhancing the home literacy environment (HLE) in which children live. In this study a non-intensive intervention procedure was developed to improve HLE and linguistic competencies of 125 German…

This article argues that Vygotsky's choice of word meaning as the basic unit of analysis for cultural psychology connects him to a German psycholinguistic tradition--exemplified in the work of G. W. F. Hegel and J. G. Herder--distinct from the Marxist tradition. While later commentators criticize Vygotsky's reliance on word meaning, arguing that…
