Cultural background can influence cognition, including executive functions (EFs), abilities that encompass skills responsible for self-regulation of thoughts and behavior. The seminal unity and diversity model of EFs proposes the existence, in adulthood, of at least three correlated but separable EF latent (shared variance in more than one…

In the last decade different instruments were developed to empirically test the TPACK theoretical framework. The TPACK for Meaningful Learning survey was the first survey to obtain statistical validation for all seven predicted constructs. In the present work we used a version of the TPACK for Meaningful Learning survey adapted and validated in…

Substantial evidence endorses the early assessment of cognitive development to promote children's developmental health and well-being. Especially in the Brazilian context, there is a paucity of standardized screening and assessment tools with normative data to evaluate young children. This study provided initial reliability and validity evidence…

This study explored student and instructor perceptions of personal mobile device usage and policies for appropriate practices in the classroom at a Brazilian higher education institution. The study also explored significant differences in perceptions, and relationships between perceptions and demographic data. A total of 176 undergraduates and 13…

Survey researchers are increasingly concerned that the presence of other people (bystanders) may affect data quality in structured, face-to-face survey interviews. In this article, we study bystanders using data from 15,309 face-to-face surveys about technology from Ghana, Nigeria, Uganda, Brazil and Guatemala. Our analysis (1) describes the…

Our goal was to investigate the role of body mass index (BMI) and motor competence (MC) in children's physical activity (PA) levels during physical education (PE) classes. We assessed PA levels of 5-to-10-year old children ("n" = 264) with pedometers in four PE classes. MC was assessed using the TGMD-2 and BMI values were classified…

This paper argues that conflicting results from previous literature--related to the effect of economic conditions on child labor--derive from different income and substitution effects implicit in different types of income variation. We use agricultural shocks to local economic activity in Brazil (coffee production) to distinguish between increases…

The objective of this exploratory study is to characterize by means of drawings if the developmental patterns in the graphic representation of organ and organ systems progresses related to age of participants. Secondly, whether there is an integration of sex organs into the internal body image. The drawings representing the inside of the body in…

Aim: To investigate the relation between head growth at different periods and IQ at 8 years, and to identify factors associated with more rapid head growth. Method: Two parallel cohorts of term low birthweight (LBW) and appropriate birthweight (ABW) infants were enrolled at birth in northeast Brazil. Anthropometric measurements were made at birth,…

Objective: To identify risk factors for poor child mental health in the southeastern Brazilian municipality of Taubate. Method: In 2001 we carried out a representative school-based survey of Brazilian schoolchildren ages 7 to 14 years (response rate, 83%). We collected extensive data on child mental health and on potential risk and protective…

Men and women in Turkey and Brazil completed the Ambivalent Sexism Inventory (Glick & Fiske, 1996) and measures of attitudes about wife abuse. In both nations hostile sexism (HS) and benevolent sexism (BS) positively correlated with attitudes that legitimize abuse. Regression analyses revealed that HS accounted for unique variance, but BS…
