A distinction can be drawn between extensive and intensive quantities. Extensive quantities (e.g., volume, distance), which have been the focus of developmental research, depend upon additive combination. Intensive quantities (e.g., density, speed), which have been relatively neglected, derive from proportional relations between variables. Thus,…

The present study examined age-related patterns in children's anxiety-related interpretations and internal attributions of physical symptoms. A large sample of 388 children aged between 4 and 13 years completed a vignette paradigm during which they had to explain the emotional response of the main character who experienced anxiety-related physical…

Care ethics, and moral sentimentalism more generally, have not developed a picture of moral education that is comparable in scope or depth to the rationalist/Kantian/Rawlsian account of moral education that has been offered by Lawrence Kohlberg. But it is possible to do so if one borrows from the work of Martin Hoffman and makes systematic use of…

Babbling between the ages of 8 and 19 months was examined in 19 children, 13 of whom were at high risk for reading disorder (RD) and 6 normally reading children at low familial risk for RD. Development of syllable complexity was examined at five periods across this 11-month window. Results indicated that children who later evidenced RD produced a…

This study explored the criteria that children and adults use when evaluating the niceness of a character who is distributing resources. Four- and five-year-olds played the "Giving Game", in which two puppets with different amounts of chips each gave some portion of these chips to the children. Adults played an analogous task that mimicked the…

A recent study by Apperly et al. (2006) found evidence that adults do not automatically infer false beliefs while watching videos that afford such inferences. This method was extended to examine true beliefs, which are sometimes thought to be ascribed by "default" (e.g., Leslie & Thaiss, 1992). Sequences of pictures were presented in which the…

Research on cognitive load theory (CLT) has not yet provided facet-specific measures of cognitive load. The lack of valid methods to measure intrinsic, extraneous and germane cognitive load makes it difficult to empirically test theoretical explanations of effects caused by manipulations of instructional designs. This situation also imposes…

Novelty seeking is viewed as adaptive, and novelty preferences in infancy predict cognitive performance into adulthood. Yet 7-month-olds prefer familiar stimuli to novel ones when searching for hidden objects, in contrast to their strong novelty preferences with visible objects (Shinskey & Munakata, 2005). According to a graded representations…

This study examined mother-child shared book reading behaviors before and after participation in a random-assignment responsive parenting intervention called Play and Learning Strategies (PALS) that occurred during infancy (PALS I), the toddler-preschool (PALS II) period, or both as compared with a developmental assessment (DAS) intervention (DAS…

Self-concept and ego development, two intertwined aspects of self-indicating well-being and social-cognitive maturation, respectively, were examined in a representative sample of deaf adolescents of normal intelligence (N = 68), using translated and adapted versions of Harter's (1988, "Manual for the self-perception profile for adolescents".…

Although conversations have been identified as an important means to promote young learners' language development, preschool children often have limited opportunities to be involved in complex conversations. This study examined preschool adaptations of Instructional Conversation, a small group discussion between teachers and children in which…

This paper presents initial results from a pilot evaluation of the pre-K component of a new school-based intervention strategy (Social, Emotional, and Cognitive Understanding and Regulation in education, SECURe) for pre-kindergarten through 3rd grade that is designed to build skills in social-emotional learning (focusing on executive function and…

In May 2010, the Center for Juvenile Justice Reform (CJJR) at Georgetown University released the monograph "Addressing the Unmet Educational Needs of Children and Youth in the Juvenile Justice and Child Welfare Systems" (Leone & Weinberg, 2010). The monograph examined a number of topics relevant to the education and experiences of…

Though the No Child Left Behind Act of 2001 requires secondary students with Asperger's syndrome (AS) to take high-stakes mathematical tests, many students with AS exhibit weaknesses in mathematical and executive functioning skills. The purpose of this mixed-methods case study was to explore the use of differentiated mathematical strategies with…

The parenting gap is a big factor in the opportunity gap. The chances of upward social mobility are lower for children with parents struggling to do a good job--in terms of creating a supportive and stimulating home environment. Children lucky enough to have strong parents are more likely to succeed at all the critical life stages, which means…
