Contributions of shared book reading to children's learning of new semantic facts through memory integration.

Young children rapidly learn facts about the world. One mechanism supporting knowledge acquisition is memory integration: derivation of new knowledge by combining separate, yet related facts accumulated over time. There are both developmental changes and individual differences in young children's learning through memory integration. However, there is little research on how everyday social interactions may promote memory integration and contribute to individual differences. Accordingly, we investigated how the everyday social interactions of caregiver-child shared book reading support 5- to 6-year-olds' memory integration (N = 82 parent-child dyads; 47 female children; M age 6.10; 56.5% White non-Latinx, 15% Black, 6% White Latinx, 5.5% Asian, 17% more than one race). Caregivers read a narrative book that included opportunities to integrate facts. Half the dyads were assigned to an embedded questions condition (questions on facts included throughout the book) and half to a no embedded questions condition (statements only). We measured dyads' extratextual talk while reading for the extent to which they integrated the facts (integration talk). Children's learning was tested with both memory integration and fact recall questions. Dyads in the embedded questions condition had more integration talk. The extent to which the dyads integrated while reading predicted children's integration performance, above and beyond condition effects. This effect was specific to memory integration: integration talk nor condition accounted for fact recall. These results suggest that shared book reading can support young children's integration, especially when books engage dyads through embedded questions and dyads integrate facts while reading.

Young children's science learning from narrative books: The role of text cohesion and caregivers' extratextual talk.

One way to support young children's factual learning is through shared book reading (reading books with a knowledgeable other). Many books that teach factual content are narrative in structure, in which factual content is embedded within a fictional storyline. However, there are gaps in our understanding of factors influencing children's factual learning from narrative books. In this experiment, 38 caregivers and their 4- to 5-year-old children from the Southeastern United States participated. Each caregiver read to their child two narrative books on science concepts. The books varied in their levels of cohesion (e.g., drawing connections between textual elements and providing details and comparisons). We coded caregivers' extratextual talk while reading for the extent to which it emphasized science information (informational highlighted talk) or went beyond the text to provide further related information (informational elaborative talk). Children's recall of the books' science and story content was tested in free and probed recall formats. We found that children had higher recall of the story content, even though caregivers emphasized the science content through their highlighted extratextual talk. Caregivers used more elaborative extratextual talk with the low cohesion book, perhaps as compensation for the book's lack of cohesion. However, children's recall of the science content was most strongly predicted by the books' cohesion and caregivers' highlighted extratextual talk. These results emphasize the important role that books' textual features and caregivers' extratextual talk during book reading have on young children's factual learning from narrative books.

The influence of books' textual features and caregivers' extratextual talk on children's science learning in the context of shared book reading.

During early childhood, reading books with one's caregiver (shared book reading) is a valuable means of supporting learning. Yet, there are gaps in our understanding of the influence of shared book reading on young children's science learning. The current research bridges this gap by examining the pedagogical quality of science books in preschool-aged children's environments and investigating how such books influence children's learning and caregivers' extratextual talk during shared book reading. In Study 1, we coded 60 science books that were readily available in young children's environments within the United States. The books were designed for English speakers and recommended for preschool-aged children. We coded the books for the extent to which they were Coherent (elaborated on facts presented by providing details, examples, comparisons, etc.) and included Embedded Questions. However, many books were low in Cohesion and Embedded Questions and were of low pedagogical quality. In Study 2, we tested thirty-eight 4- to 5-year-old children (55% female, 76% White) and their caregivers in the Southeastern United States. We assessed the influence of books' levels of Cohesion and Embedded Questions and of caregivers' Elaborative extratextual talk during shared book reading on children's science learning. Children learned more from books high in Cohesion, irrespective of levels of Embedded Questions and caregivers' Elaborative Talk. Additionally, children learned more from books high in Embedded Questions when caregivers used more Elaborative Talk. This research highlights the importance that books' textual features and social interactions during shared book reading have in promoting early science learning.

Examining the role of external language support and children's own language use in spatial development.

This research investigated whether an experimental manipulation providing children with external language support reflects developmental processes whereby children come to use language within spatial tasks. A total of 121 3- to 6-year-old children participated in language production and spatial recall tasks. The Production task measured children's task-relevant descriptions of spatial relations on the testing array. The Recall task assessed children's delayed search for hidden object locations on the testing array relative to one or more spatial reference frames (egocentric, room-centered, and intrinsic). During the Recall task, the experimenter provided children with either descriptive or nondescriptive verbal cues. Results showed that children's task-relevant language production improved with age and the effects of language support on spatial performance decreased with age. However, children's production of task-relevant language did not account for effects of language support. Instead, children benefited from language support irrespective of their task-relevant language production. These results suggest that verbal encoding is not a spontaneous process that young children use in support of their spatial performance. In addition, experimental manipulations of language support are not fully reflective of the ways in which children come to use language within spatial tasks.

Developmental differences in reactivation underlying self-derivation of new knowledge through memory integration.

Self-derivation of novel facts through integration of memory content is fundamental to acquiring new knowledge and a means of building a semantic knowledge base. It involves combining memory content acquired across separate episodes of learning to generate new knowledge that was not explicitly taught in either episode. To self-derive, one needs to reactivate earlier learned memory content upon exposure to related content and then integrate the learning episodes. Previous research found developmental differences in the conditions under which integration occurs. Adults spontaneously integrate whereas 7- to 9-year-old children seemingly integrate only upon direct tests that verbally prompt for integration. Yet it is unclear whether children engage in the preliminary process of reactivation prior to the direct tests. To address this gap in the current research, we developed an eye-tracking paradigm and tested whether adults and 7- to 9-year-old children engage in the process of reactivation prior to direct tests. The direct tests verbally prompted for integration of memory content requiring self-derivation through both open-ended and forced-choice formats. Both adults and children engaged in reactivation prior to the direct tests. The extent of their reactivation predicted their performance on the direct tests. However, adults showed stronger evidence of reactivation and performed better than children on the direct tests. This work contributes to understandings of developmental differences in the underlying processes involved in the development of new knowledge.
