Preadolescence is an important period for the consolidation of certain arithmetic facts, and the development of problem-solving strategies. Obese subjects seem to have poorer academic performance in math than their normal-weight peers, suggesting a negative effect of obesity on math skills in critical developmental periods. To test this hypothesis, event-related potentials were collected during a delayed-verification math task using simple addition and subtraction problems in obese [above 95th body mass index percentile] and non-obese preteens with different levels of math skill; (...) thirty-one with low math skills and thirty-one with high math skills. No significant differences between weight groups were observed in task accuracy regardless of their mathematical skill level. For ERPs, electrophysiological differences were found only in the subtraction condition; participants with obesity showed an electrophysiologic pattern associated with a reduced ability to allocate attention resources regardless of their math skill level, these differences were characterized by longer P300 latency than their normal-weight peers. Moreover, the participants with obesity with high math skills displayed hypoactivity in left superior parietal lobule compared with their normal-weight peers. Additionally, obese preteens with low math skills displayed smaller arithmetic N400 amplitude than non-obese participants, reflecting difficulties in retrieving visual, semantic, and lexical information about numbers. We conclude that participants with obesity are less able than their normal-weight peers to deploy their attention regardless of their behavioral performance, which seems to have a greater effect on obese participants with low math skills because they also show problems in the retrieval of solutions from working memory, resulting in a delay in the development of mathematical skills.

TWEEN POP examines the creation of the "tween" in the early 2000s as a gendered and raced consumer audience. The tween, aged nine to twelve, and usually thought of as a white girl, occupies a temporality between childhood and adolescence: she has aged out of children's products but is too young to fully engage in marketing directed at teenagers. But, as Tyler Bickford argues, this seemingly narrow market grew to broadly include four to fifteen year olds, with producers and marketers (...) pulling upwards and downwards by creating material that would attract younger viewers and teenagers, thereby creating a demographic that expanded, rather than limited, the traditional reach of child and teenage markets. According to Bickford, the key to this expansion was pop music, as it provided an intensity of experience that mirrored childhood in its investments in emotional authenticity, cultural value, and relational intimacies. In other words, pop music needed to be both intimate and public--a tension that Bickford argues defined the tween's positionality as well--and tween pop did so by pairing the mainstream pop of adulthood with images and lyrics suitable for younger audiences. Throughout the book, Bickford reveals how childhood's status as a private domestic position outside of politics was not a hindrance to the cultivation of children as a mass audience but rather was the very foundation of that project. By creating an intimate public of tween pop, the tween music industry was able to position tweens as still within the private domestic sphere of family life, but connected in a broader public of other tween-pop-listening tweens. Chapter 1 looks at Kidz Bop music videos to argue that the tween music industry framed childhood domesticity as complementary to participation in a public culture. Chapter 2 focuses on Disney Channel's popular music programs' efforts to engage older children, particularly older girls, in their marketing tactics. Chapter 3 analyzes the Disney Channel show Hannah Montana and its foregrounding of tensions between girlhood, public culture, and family. Chapter 4 attends to how whiteness served as central to the tween construction of innocence and childhood. Bickford concludes the book by periodizing the tween moment as the decade from 2001 to 2011, and then outlines the developments in popular culture for children since that time. This book will be of interest to students and scholars of ethnomusicology, feminism and gender studies, and cultural studies. (shrink)

Summary The study used group discussions and a documentary method to investigate which micro-processes at the nexus of family, peer group, and school encouraged and discouraged seventh-grade girls' involvement in club sports, and what collective orientations accompanied these processes. Based on reconstructed micro-processes and orientations, two selected groups of girls in intermediate and upper secondary school were compared to determine how involvement in club sports differed by school type. One result was that the upper secondary school students were part of (...) several social reference groups with a sports orientation simultaneously, whereas the intermediate secondary school students were part of fewer social reference groups overall, and the groups they were part of tended to have other orientations than sports. The upper secondary students benefited during their childhood and preteen years from interactions among social reference groups that were conducive to club sports involvement, whereas intermediate secondary students were exposed to interactions that inhibited their involvement in sports. This inhibiting effect results from a lack of family influences, negative sports experiences in school, and in particular the high significance of peer groups that pursue other interests having little to do with club sports.
