To explore the potential contribution of parents' causal talk to preschooler's emerging scientific literacy and related interests, we observed 153 parent-child dyads playing together in a museum and in the lab. As in previous work, the frequency with which parents referenced causal information in their speech predicted the strength of their children's causal stance. In addition, the frequency with which parents invited their children to explain causal phenomena, but not the frequency with which they provided explanations to their children, was related to children's scientific literacy. These associations held even when controlling for children's parent-reported exposure to science in the home, as well as their general cognitive skills. Although causal conclusions are precluded by the correlational design, this research is consistent with the possibility that parents begin shaping their children's scientific engagement and literacy when they are as young as three years of age.
Socioeconomic status (SES) has been repeatedly linked to the developmental trajectory of vocabulary acquisition in young children. However, the nature of this relationship remains underspecified. In particular, despite an extensive literature documenting young children's reliance on a host of skills and strategies to learn new words, little attention has been paid to whether and how these skills relate to measures of SES and vocabulary acquisition. To evaluate these relationships, we conducted two studies. In Study 1, 205 2.5‐ to 3.5‐year‐old children from widely varying socioeconomic backgrounds were tested on a broad range of word‐learning skills that tap their ability to resolve cases of ambiguous reference and to extend words appropriately. Children's executive functioning and phonological memory skills were also assessed. In Study 2, 77 of those children returned for a follow‐up session several months later, at which time two additional measures of vocabulary were obtained. Using Structural Equation Modeling (SEM) and multivariate regression, we provide evidence of the mediating role of word‐learning skills on the relationship between SES and vocabulary skill over the course of early development.
Two-hundred and three college women participated in a 16-minute strength and conditioning group fitness class. Participants were randomly assigned to a class that featured either appearance-focused motivational comments by the instructor (e.g., “Blast that cellulite!”) or function-focused comments (e.g., “Think of how strong you are getting!”). Body satisfaction from pre-test to post-test increased overall, but those in the function-focused (as opposed to appearance-focused) condition experienced a significantly greater increase in body satisfaction. A similar pattern was observed for positive affect. Additionally, those in the function-focused condition described the class in more positive terms and reported experiencing less body surveillance during the class. These findings are consistent with research suggesting that exercise can improve mood and body satisfaction, but also suggest that a more function-focused class can lead to even greater improvements. The motivational comments fitness instructors use may have a notable impact on women’s mood, body satisfaction, and body surveillance.
Fostering early literacy depends in part on engaging and inspiring children's early interest in reading. Enriching the causal content of children's books may be one way to do so, as causal information has been empirically shown to capture children's attention. To more directly test whether children's book preferences might be driven by causal content, we created pairs of expository books closely matched for content and complexity, but with differing amounts of causal information embedded therein. Three and 4 years old participants (n = 48) were read both books and their interests and preferences were evaluated. When asked to choose, children preferred the highly causal over the minimally causal books. Results are discussed in terms of broader implications for creating books that optimally engage young children, as well as guiding book selections parents and educators make in their endeavors to promote interest in reading and early literacy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
