The aim of this study was to investigate the validity of the Rotterdam Transition Profile (RTP) to describe the transition process from childhood to adulthood in young adults with cerebral palsy (CP). Participants were recruited from rehabilitation centres and hospital departments of rehabilitation. In total, 81 young adults (47 males, 34 females)…

Patterns of development of ToM-emotion abilities in intellectually disabled (ID) children and typically developing (TD) children matched on their developmental age were investigated. The links between cognition, language, social understanding and ToM-emotion abilities were examined. EDEI-R (Perron-Borelli, M. (1996). "Echelles Differentielles…

This paper reviews the use of eye tracking measures (saccades, smooth-pursuit eye movements, fixations during scene and face perception, and pupillary dilation) to study typical and clinical populations of children and adolescents and evaluates the use of these measures. The studies are evaluated with a focus on points that may be of general…

It is widely assumed that ultimate attainment in adult second language (L2) learners often differs quite radically from ultimate attainment in child L2 learners. This article addresses the question of whether learners at different ages also show qualitative differences in the process of L2 acquisition. Longitudinal production data from two…

In this study we examined the development of three action monitoring event-related potentials (ERPs)--the error-related negativity (ERN/Ne), error positivity (P[subscript E]) and the N2--and estimated their neural sources. These ERPs were recorded during a flanker task in the following groups: early adolescents (mean age = 12 years), late…

Previous definitions of sexually abusive behavior in children and adolescents were deficient in failing to (1) highlight salient neuropsychological elements and antisocial behaviors that may contribute to a youth's functioning; (2) discriminate among possible types of coercion (e.g., manipulation, threats, physical force, and use of weapons); and…

This study characterizes several aspects of emerging ethnic identity in childhood and its associations with interethnic group social preferences. Understanding these processes is important, as early interethnic group social practices may form a foundation for later interethnic group attitudes and behaviors in adolescence. Children of Cambodian,…

This study aimed to investigate the effectiveness of a school-based universal preventive stress management training program for early and middle adolescents in comparison with a no-treatment control group. The study examined the intervention effects of age (early versus middle adolescents) and gender on perceived stress, interpersonal coping, and…

Two cohorts of alumni, leading-edge and trailing-edge baby boomers, first tested in their college years, were followed to ages 43 (N = 136) and 54 (N = 182) on a measure of Erikson's theory of psychosocial development. Hierarchical linear modeling was used to model the trajectory of growth for each psychosocial issue across middle adulthood. As…

Three experiments investigated 14-, 18-, and 24- month-old infants' understanding of visual perception. Infants viewed films in which a protagonist was either able to view the location of a hidden object (Visual Access condition) or was blindfolded when the object location was revealed (No Visual Access condition). When requested to find the…

We are pleased with the commentators' thoughtful reactions to our study, as they make it clear that the study met its major goal--identifying age differences that suggest developmental changes in the learning process and the strengthening of executive processes in the second decade of life.

The authors investigated the differences between 8-year-olds (n = 80) and adults (n = 80) in recognition of felt versus faked enjoyment smiles by using a newly developed picture set that is based on the Facial Action Coding System. The authors tested the effect of different facial action units (AUs) on judgments of smile authenticity. Multiple…

How does the development and consolidation of perceptual, attentional, and higher cognitive abilities interact with language acquisition and processing? We explored children's (ages 5-17) and adults' (ages 18-51) comprehension of morphosyntactically varied sentences under several competing speech conditions that varied in the degree of attentional…

This article presents the author's response to Wyn and Woodman (2006) who have urged shifting youth research away from a transition paradigm to a generation paradigm. The evidence that they marshal in support is mainly from Australia, but their arguments are intended to be relevant throughout the western world. Here, the author argues that Wyn and…

A research study surveyed 946 volunteers from congregations who were actively involved in community service, as well as 3,959 other congregational attenders who were not involved in volunteer service, to understand the relationship between service learning and faith development. Findings show that service-learning is powerfully related to a mature…
