It is possible that statistical learning (SL) plays a role in almost every mental activity. Indeed, research on SL has grown rapidly over recent decades in an effort to better understand perception and cognition. Yet, there remain gaps in our understanding of how SL operates, in particular with regard to its (im)mutability. Here, we investigated…

According to a recent evolutionary life history model of development proposed by Ellis, Figueredo, Brumbach, and Schlomer (2009), growing up in harsh versus unpredictable environments should have unique effects on life history strategies in adulthood. Using data from the Minnesota Longitudinal Study of Risk and Adaptation, we tested how harshness…

In this longitudinal study, we examined whether certain types of stressful events and how individuals respond to these events would explain gender differences in depressive symptoms among adolescents. We hypothesized that certain stressful events would mediate the relationship between gender and depressive symptoms. We also hypothesized that…

The purpose of this paper is to examine the predictors of children's media use in the USA, comparing cross-sectional and longitudinal analyses. Data come from Waves 1 and 2 of the Child Development Supplement (CDS-I; CDS-II), a nationally representative sample of American children aged 0-12 in 1997 and 5-18 in 2002. Twenty-four hour time use…

An investigation was conducted into the visual and auditory temporal processing profiles of two groups of 4- to 6-year-old children: "pre-alphabetic" children, who showed no alphabetic ability (failing to read any non-words in a test), and those who demonstrated some alphabetic ability. This "alphabetic" group showed higher scores in reading and…

Prenatal maternal stress has been shown to affect postnatal development in animals and humans. In animals, the morphology and function of the offspring's hippocampus is negatively affected by prenatal maternal stress. The present study prospectively investigated the influence of prenatal maternal stress on learning and memory of 112 children (50…

With increasing numbers of women joining the evening/nighttime workforce, there is a need for quality childcare during these hours. This project, conducted in Japan, sought to compare the effects of expanded childcare on the development and adaptation of 866 young children after one year. Parents completed a survey on the childrearing environment…

Maternal depression is associated with adverse child development, but little is known about the effects of paternal depression. This pilot study estimated the prevalence of paternal depression and mood state, and assessed the relationship between paternal mood and infant temperament. The participants in the study were 98 fathers of newborn babies.…

Discusses the structure, reliability, stability, validity and usefulness of the Brazelton Neonatal Behavioral Assessment Scale (NBAS) and the results of factor and regression analyses of data collected using the NBAS. (Author/BH)
