This article presents results from a large population-based study of early communicative development in Norwegian children using an adaptation of the MacArthur-Bates Communicative Development Inventories, comprising 6574 children between 8 and 36 months. Data were collected via the Internet. In accordance with similar studies from other languages,…

Two studies examined the hypothesis that the evaluation of developmental stability changes across adulthood. Results of Study 1 ("N" = 119) supported the expectation that older adults ("M"[subscript age] = 65.29 years)--compared to younger ("M"[subscript age] = 23.38 years) and middle-aged adults…

Little research has been conducted on whether deficits in developmental functioning affect the range of core symptoms for autism spectrum disorders (ASD). This study represents a first attempt to determine whether developmental level has an effect on the expression of ASD symptoms in infants and toddlers. Eight hundred and fifty-three infants were…

Available evidence indicates that experience with one face from a specific age group improves face-processing abilities if acquired within the first 3 years of life but not in adulthood. In the current study, we tested whether the effects of early experience endure at age 6 and whether the first 3 years of life are a sensitive period for the…

Background: This study examines how those planning futures for young people with moderate-profound intellectual disabilities invoke, deploy and interpret contrasting definitions of adulthood and perceived capacity for autonomy and self-determination. Methods: Twenty-eight young people were followed through transition from children: s to adult…

There are several myths about neuroscientific findings that are widespread in education. Some of these myths are left brain/right brain, critical periods for learning, and gender differences in the brain. Belief in these "neuromyths" can negatively affect how we teach children. But ignoring important findings from neuroscience can be just as…

Almost 200,000 infants and toddlers come into the child welfare system each year. They do so during the period of the most rapid brain development. Maltreatment can damage the architecture of the developing brain, with lifelong consequences for both baby and society. The child welfare system has not done well at addressing the developmental needs…

Fairness is central to morality. Previous research has shown that children begin to understand fairness between the ages of four and six, depending on the context and method used. Within distributive contexts, there is little clear evidence that children have a concept of fairness before the age of five. This research, however, has mostly examined…

In this chapter, the authors extend the ideas around the development of self-regulation and its impact on development by proposing a life-span, relational, public health model. They propose that the role of self-regulation should be understood across transitions from childhood to adulthood and through an individual and community perspective,…

Research has shown that a hallmark of adolescent development is the growing capacity to interpret human intentionality. In this chapter, the authors examine developmental change in this capacity, which they have termed interpretive thought, in two types of stories, family and autobiographical, told by Canadian youth aged ten to seventeen years.…

During the first years of life, children progress through a number of developmental stages related to feeding. By the age of five, a child typically has the skills, behaviors and habits that will be used throughout their lives. However, data indicates that 60 to 70% of children with disabilities have one or more feeding difficulties. Importantly,…

Using data from a longitudinal study of Mexican-origin girls (ages 11-17 at Time 1), we examined sociocultural (i.e., family structure, nativity, and acculturation), interpersonal (i.e., supportive parenting and conflict), and developmental (i.e., menarche timing and autonomy expectations) predictors of sexual initiation. Using Cox proportional…

This study examined the development of school-related causality beliefs which are children's generalized perceptions of the utility or power of different categories of specific means in producing school outcomes. Based on the action theory perspective, we analyzed the developmental model of these beliefs as well as the trajectories of the…

Few, if any, researchers would deny the existence of the developmental stages of language learning. However, there are questions about the applicability and the importance of the stages in pedagogy. Up to this point, these questions regarding the ESL (English as a second language) stages have never been addressed in a Japanese post-secondary…

Almost all teenage magazines invite readers to submit questions concerning relationships, published as letters to the editor, popularly called "advice columns," often containing explicit questions about sexuality. This study aims to examine, firstly, how themes related to sexual initiation are presented in letters to the editor published…
