Do cavies talk? The effect of anthropomorphic picture books on children\u27s knowledge about animals

Many books for young children present animals in fantastical and unrealistic ways, such as wearing clothes, talking and engaging in human-like activities. This research examined whether anthropomorphism in children\u27s books affects children\u27s learning and conceptions of animals, by specifically assessing the impact of depictions (a bird wearing clothes and reading a book) and language (bird described as talking and as having human intentions). In Study 1, 3-, 4-, and 5-year-old children saw picture books featuring realistic drawings of a novel animal. Half of the children also heard factual, realistic language, while the other half heard anthropomorphized language. In Study 2, we replicated the first study using anthropomorphic illustrations of real animals. The results show that the language used to describe animals in books has an effect on children\u27s tendency to attribute human-like traits to animals, and that anthropomorphic storybooks affect younger children\u27s learning of novel facts about animals. These results indicate that anthropomorphized animals in books may not only lead to less learning but also influence children\u27s conceptual knowledge of animals

Validation of the StimQ2: A parent-report measure of cognitive stimulation in the home.

Considerable evidence demonstrates the importance of the cognitive home environment in supporting children's language, cognition, and school readiness more broadly. This is particularly important for children from low-income backgrounds, as cognitive stimulation is a key area of resilience that mediates the impact of poverty on child development. Researchers and clinicians have therefore highlighted the need to quantify cognitive stimulation; however existing methodological approaches frequently utilize home visits and/or labor-intensive observations and coding. Here, we examined the reliability and validity of the StimQ2, a parent-report measure of the cognitive home environment that can be delivered efficiently and at low cost. StimQ2 improves upon earlier versions of the instrument by removing outdated items, assessing additional domains of cognitive stimulation and providing new scoring systems. Findings suggest that the StimQ2 is a reliable and valid measure of the cognitive home environment for children from infancy through the preschool period

The Children, Caregivers, and Community (C3) study of together growing strong: A protocol for an observational, place-based initiative in Sunset Park, Brooklyn.

Reaching population-level impact for families in poverty requires moving beyond a sole focus on individuals, to a wider focus on interactions between individuals and their broader environmental contexts. Place-based initiatives have emerged as a policy response to promote community-level change around these broader interactions between individuals and their local communities through addressing long-standing disparities in housing, employment, education, and health. Together Growing Strong (TGS) is one such place-based initiative focused on transforming the health, wellbeing, and development of young children and their families in Sunset Park, Brooklyn. The Children, Caregivers, and Community (C3) Study is an outcomes-based study designed to assess the trajectories of children and families in Sunset Park along indicators such as family health and wellbeing and child development in relation to TGS program participation. The aims, scope, and protocol of the C3 Study are the subjects of this paper

\u3ci\u3eDrosophila\u3c/i\u3e Muller F Elements Maintain a Distinct Set of Genomic Properties Over 40 Million Years of Evolution

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D. erecta, D. mojavensis, and D. grimshawi F elements and euchromatic domains from the Muller D element. We find that F elements have greater transposon density (25–50%) than euchromatic reference regions (3–11%). Among the F elements, D. grimshawi has the lowest transposon density (particularly DINE-1: 2% vs. 11–27%). F element genes have larger coding spans, more coding exons, larger introns, and lower codon bias. Comparison of the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation. F element genes have lower estimated DNA melting temperatures than D element genes, potentially facilitating transcription through heterochromatin. Most F element genes (~90%) have remained on that element, but the F element has smaller syntenic blocks than genome averages (3.4–3.6 vs. 8.4–8.8 genes per block), indicating greater rates of inversion despite lower rates of recombination. Overall, the F element has maintained characteristics that are distinct from other autosomes in the Drosophila lineage, illuminating the constraints imposed by a heterochromatic milieu
