Shared reading research has become increasingly multidisciplinary and has incorporated a multitude of assessment methods. This calls for an interdisciplinary perspective on children’s shared reading experiences at home and at the child care center and their relationships to oral language development. Here, we first discuss Bronfenbrenner’s bioecological model of human development (Bronfenbrenner and Morris, 2006) regarding the relationship between shared storybook reading and oral language development. Second, we develop a framework for investigating effects of shared reading on language development in two important microsystems: the home literacy environment (HLE) and the child care literacy environment (CCLE). Zooming in on shared storybook reading as a proximal process that drives oral language development, we then develop a triad model of language learning through shared storybook reading that integrates approaches and evidence from educational psychology, developmental psychology, psycholinguistics, and corpus linguistics. Our model describes characteristics of children, adults, and books, and how their interplay influences shared reading activities. Third, we discuss implications for the Home Literacy Model (Sénéchal and LeFevre, 2002, 2014) regarding the conceptualization of shared reading as an important source of oral language development. Finally, to facilitate integrated research designs that include the two most important microsystems, we provide a critical discussion of assessment methods used in research that investigates the HLE and the CCLE and relate them to the shared reading triad in our bioecological model of shared storybook reading. We conclude with directions for future research.

The development of preschoolers’ language skills is influenced by literacy environments and individual differences in storybook exposure. Extant research is limited as most studies (a) investigate the effects on lower level language (LLL; e.g., vocabulary, grammar), but not the effects on higher level language (HLL; e.g., comprehension monitoring, narrative comprehension), and (b) focus on shared reading in the home literacy environment (HLE), but not on the child care literacy environment (CCLE) and the child as active literacy agent. We addressed these two gaps. First, we investigated the contributions of the HLE and the CCLE to the storybook exposure of 201 German preschoolers (M_Age = 5; 5 years). A multilevel model showed that parents’ storybook exposure was the most important predictor of children’s storybook exposure. By contrast, child care workers’ storybook exposure was not a significant predictor. Second, we explored the unique contributions of HLE, CCLE, and preschoolers’ storybook exposure to LLL and HLL skills. Multilevel models showed that children’s storybook exposure explained unique variance not only in LLL skills, but also in HLL skills. Literacy environments explained additional variance in LLL skills. In sum, our results suggest that literacy environments are differentially related to children’s storybook exposure and language skills. Our finding that children’s storybook exposure was a unique predictor of vocabulary, grammar, comprehension monitoring, and narrative comprehension indicates that shared book reading has the potential to foster a range of early literacy skills which predict reading comprehension.

Children in transition from kindergarten to school develop fundamental skills important for the acquisition of reading and writing. Previous research pointed towards substantial correlations between specific language- and music-related competencies as well as positive transfer effects from music on pre-literacy skills. However, until now the relationship between diverse music and language competencies remains unclear. In the present study we used a comprehensive approach to clarify the relationships between a broad variety of language and music skills on different levels, not only between but also within domains. In order to do so, we selected representative language- and music-related competencies and systematically compared the performance of N = 44 5- to 7-year-old children with a control group of N = 20 young adults aged from 20 to 30. Competencies were organized in distinct levels according to varying units of vowels/sounds, words or syllables/short melodic or rhythmic phrases, syntax/harmony and context of a whole story/song to test for their interrelatedness within each domain. Following this, we conducted systematic correlation analyses between the competencies of both domains. Overall, selected competencies appeared to be appropriate for the measurement of language and music skills in young children with reference to comprehension, difficulty and a developmental perspective. In line with a hierarchical model of skill acquisition, performance on lower levels was predictive for the performance on higher levels within domains. Moreover, correlations between domains were stronger for competencies reflecting a similar level of cognitive processing, as expected. In conclusion, a systematic comparison of various competencies on distinct levels according to varying units turned out to be appropriate regarding comparability and interrelatedness. Results are discussed with regard to similarities and differences in the development of language and music skills as well as in terms of implications for further research on transfer effects from music on language.

Leisure reading is a main contributor to print exposure, which is in turn related to individual differences in reading and language skills. The Author Recognition Test (ART) is a brief and objective measure of print exposure that has been used in reading research since the 1990s. Life span studies have reported contradicting results concerning age differences in print exposure, possibly due to the use of ART versions that differed regarding authors’ mean publication year. We investigated effects of participant age and authors’ mean publication year, literary level, and circulation frequency on author recognition probability between adolescence and old age (N = 339; age 13–77 years). An explanatory item response analysis showed that participant age and circulation frequency were positively related to recognition probability. Mean publication year was negatively related to recognition probability, indicating that recent authors who have been widely read for only a few years were less often recognized than classic authors who have been widely read for several decades. The relation between participant age and recognition probability was moderated by author variables. For classic authors, the recognition probability increased between adolescence and old age. By contrast, for recent authors, the recognition probability increased only between adolescence and middle age. Our results suggest that the mean publication year is a key author variable for the detection of print exposure differences between young, middle-aged and older adults. We discuss implications for author selection when updating the ART and for measuring print exposure in age-diverse samples.

The present study investigated the development and training of music competencies in children in transition from kindergarten to school. In an intervention study with three experimental groups (music training, language training, no training) we investigated music performances of N = 202 5-year-old children before and after a period of 6 months. Results indicate substantial improvement in several low- and high-level musical competencies independent of children’s participation in one of the training groups. In addition, the music training group improved significantly more in their tonal discrimination, rhythm repetition, and synchronization skills compared to the no-training group. Results show that children in the language training group also improved in their music skills, which indicates noticeable overlap between these two domains. By contrast, interindividual differences in potentially relevant environmental factors, such as home musical environment and their socioeconomic status, did not affect children’s musical skills. By disentangling music training effects from musical experience based on informal exposure, the present findings contribute to the understanding of the development of various music competencies and to the effects of musical trainings in preschool.
