Using the new "emerging adulthood" developmental period (Arnett, 2000) as a theoretical framework, this article emphasizes the challenges faced by emerging adults (17- to 24-year-olds) enrolled in adult education. First, emerging adulthood as a developmental period and the additional difficulties experienced by youths with emotional,…

This study investigated how infants gather information about their environment through looking and how that changes with increases in motor skills. In Experiment 1, 9.5- and 14-month-olds participated in a 10-min free play session with both a stranger and ambiguous toys present. There was a significant developmental progression from passive to…

Disruptive behavior, including aggression, defiance, and temper tantrums, typically peaks in early toddlerhood and decreases by school entry; however, some children do not show this normative decline. The current study examined disruptive behavior in 318 boys and girls at 2, 4, and 5 years of age and frustration reactivity, physiological…

This paper reports on a study that used verbal protocols to uncover the cognitive strategies of children from Sydney, Australia, aged 8- to 9-years-old, when they were engaged in a range of word sorting and editing activities. The children's cognitive strategies have been analysed in terms of a developmental stage theory of spelling. The findings…

This paper provides information on a measure that was developed to assess children's level of development at preschool and entry to school level, as well as their readiness for formal schooling. This measure--"Who Am I?"--is based on early copying and writing skills and is designed to identify the broad stages of development that underlie…

T. S. Braver and colleagues (e.g., T. S. Braver, J. D. Cohen, & D. M. Barch, 2002) have provided a theory of cognitive control that focuses on the role of context processing. According to their theory, an underlying context-processing mechanism is responsible for the cognitive control functions of attention, inhibition, and working memory. In the…

Early childhood educators use several learning centers in a classroom to target growth in different developmental areas, but as a preschool teacher, the author was always impressed by how children addressed multiple areas of development at the sensory table. Understanding that sensory experiences were important for preschoolers, the author wanted…

Typical adults mimic facial expressions within 1000ms, but adults with autism spectrum disorder (ASD) do not. These rapid facial reactions (RFRs) are associated with the development of social-emotional abilities. Such interpersonal matching may be caused by motor mirroring or emotional responses. Using facial electromyography (EMG), this study…

Drawing on time use data from the Child Development Supplement of the Panel Study of Income Dynamics, this study identified five different profiles of shared time between parents and young people at different stages of development. In childhood, all profiles had high rates of shared television viewing, but some were oriented toward in-home…

Tertiary educators increasingly recognize the benefits for student learning of collaboration and group work; however, it is commonly perceived that examinations should be completed without the opportunity for interaction with other learners or use of relevant resources. An alternative approach is suggested in this article, based on the…

In adulthood, twice as many women as men are depressed, a pattern that holds in most nations. In childhood, girls are no more depressed than boys, but more girls than boys are depressed by ages 13 to 15. Although many influences on this emergent gender difference in depression have been proposed, a truly integrated, developmental model is lacking.…

This longitudinal study assessed multidisciplinary data on 219 children with autistic spectrum disorders from the median age of 5 (Time 1) to 8 years old (Time 2). The evolution of psychological and adaptive data was subjected to cluster analysis. Four clinically meaningful clusters emerged. The first group (21%) demonstrated the most important…

Kohlberg's characterization of moral development as displaying an invariant hierarchical order of structurally consistent stages is losing ground. However, by applying Rasch analysis, Dawson recently gave new interpretation and support to his characterization of stage development. Using Rasch models, we replicated and strengthened her findings in…

Down syndrome (DS) is the most common genetic cause of significant intellectual disability in the human population, occurring in roughly 1 in 700 live births. The ultimate cause of DS is trisomy of all or part of the set of genes located on chromosome 21. How this trisomy leads to the phenotype of DS is unclear. The completion of the DNA…

There has been much controversy over the past decades on the origins of gender differences in children's aggressive behavior. A widely held view is that gender differences emerge sometime after 2 years of age and increase in magnitude thereafter because of gender-differentiated socialization practices. The objective of this study was to test…
