Physical fitness and academic achievement in third- and fifth-grade students

The relationship between physical fitness and academic achievement has received much attention owing to the increasing prevalence of children who are overweight and unfit, as well as the inescapable pressure on schools to produce students who meet academic standards. This study examined 259 public school students in third and fifth grades and found that field tests of physical fitness were positively related to academic achievement. Specifically, aerobic capacity was positively associated with achievement, whereas BMI was inversely related. Associations were demonstrated in total academic achievement, mathematics achievement, and reading achievement, thus suggesting that aspects of physical fitness may be globally related to academic performance in preadolescents. The findings are discussed with regards to maximizing school performance and the implications for educational policies.     

Early Behavioral Inhibition and Emotion Regulation: Pathways Toward Social Competence in Middle Childhood

This study examined emotion regulation (ER) as a mediator in the relation between early behavioral inhibition (BI) and later social competence (N = 257), and whether this mediation varied depending on BI levels. Maternal report and observational measures were used to assess BI (ages 2 and 3). Children's ER strategies (age 5) and social competence with an unfamiliar peer (age 7) were measured using observational measures. Results showed that BI predicted less engaged ER strategies during a disappointment task, and engaged ER predicted higher social competence. Engaged ER mediated the effect of BI on social competence, but only for highly inhibited children. Findings elucidate developmental trajectories of risk and resilience, and suggest targeting regulatory strategies in early prevention efforts with highly inhibited children.     

Investigating Maternal Self-Efficacy and Home Learning Environment of Families Enrolled in Head Start

The aim of this study was to examine the relationships between mothers’ self-efficacy beliefs, their preschool children’s home learning environments, and literacy skills. A sample of 112 mother–child dyads was recruited from Head Start centers in rural and urban communities. The measures included maternal self-efficacy and maternal perceptions of child’s readiness to read as well as the Stipek Home Learning Activities (SHLA) scale, Home-Learning Environment Profile (HLEP), and the Stony Brook Family Reading Survey (SBFRS). Modeling path analysis was performed. Model fit indices indicated that the resulting model was a good fit for the data. Concerning the direct effects of maternal self-efficacy on home learning environment, positive significant effects for the SHLA measure as well as the HLEP were found. However, no direct effect was found with regard to maternal self-efficacy on SBFRS indicating evidence for the domain specificity of efficacy beliefs. Implications of the study include findings that higher maternal self-efficacy is related to creating a more positive home learning environment. Additionally, higher maternal perceptions of child readiness to read mediates the relationships between higher maternal self-efficacy and a more positive home literacy environment. Moreover, these findings highlight the link between home learning environment and children’s receptive vocabulary skills.     

lol: new language and spelling in instant messaging

Written communication in instant messaging, text messaging, chat, and other forms of electronic communication appears to have generated a “new language” of abbreviations, acronyms, word combinations, and punctuation. In this naturalistic study, adolescents collected their instant messaging conversations for a 1-week period and then completed a spelling test delivered over instant messaging. We used the conversations to develop a taxonomy of new language use in instant messaging. Short-cuts, including abbreviations, acronyms, and unique spellings were most prevalent in the instant message conversation, followed by pragmatic signals, such use of emoticons, emotion words, and punctuation, and typographical and spelling errors were relatively uncommon. With rare exceptions, notably true spelling errors, spelling ability was not related to use of new language in instant messaging. The taxonomy provides an important tool for investigating new language use and the results provide partial evidence that new language does not have a harmful effect on conventional written language.     

A secure base in adolescence: markers of attachment security in the mother-adolescent relationship

This study sought to identify ways in which adolescent attachment security, as assessed via the Adult Attachment Interview, is manifest in qualities of the secure base provided by the mother-adolescent relationship. Assessments included data coded from mother-adolescent interactions, test-based data, and adolescent self-reports obtained from an ethnically and socioeconomically diverse sample of moderately at-risk 9th and 10th graders. This study found several robust markers of adolescent attachment security in the mother-adolescent relationship. Each of these markers was found to contribute unique variance to explaining adolescent security, and in combination, they accounted for as much as 40% of the raw variance in adolescent security. These findings suggest that security is closely connected to the workings of the mother-adolescent relationship via a secure-base phenomenon, in which the teen can explore independence in thought and speech from the secure base of a maternal relationship characterized by maternal attunement to the adolescent and maternal supportiveness.
