Investigated children's and adolescents' involvement in mutual antipathies. Found that children and boys of all ages were more frequently involved in same-sex antipathies; involvement in mixed-sex antipathies was comparable for both genders.

Used a habituation-dishabituation procedure to test ability of 4-, 5-, and 7-month-olds to differentiate between a subjective ellipse and a nonsubjective pattern that were constructed by displacing the inducing elements of the illusory figure. Found that even 4-month-olds discriminated between the subjective ellipse and nonillusory display. This…

Examined performance on ventromedial prefrontal tasks of preschoolers with autism spectrum disorder (ASD), preschoolers with developmental delays, and typically- developing 12- to 46-month-olds, matched on mental age. Found that children with ASD performed similarly to comparison groups on all executive function tasks. Ventromedial, but not…

This longitudinal training study explored impact of social scaffolding on emergence of graphic symbol functioning and links among graphic, language, and play domains in symbolic development.

Tested predictions of dynamic field theory in study of 3-year-olds' location memory errors in task with homogeneous task space. Found that young children's spatial memory responses are affected by delay- and experience-dependent processes as well as the geometric structure of the task space. Both dynamic field theory and category adjustment models…

Examined associations between sleep and neurobehavioral functioning (NBF) in second-, fourth-, and sixth-graders.

Parents' literacy teaching related to early literacy skills, which…

Examined early development of guilt in 106 children observed in laboratory paradigms in which they were led to believe they had damaged valuable objects during 2 sessions at 22, 33, and 45 months. Found support for a mediational model in which fearful temperament contributed to guilt proneness, which served to inhibit children's tendency to…

Used prospective longitudinal design to ascertain whether different types of behavioral inhibition were stable from toddler to preschool age, and whether inhibited temperament or parenting style predicted children's subsequent social/behavioral problems. Found that traditional and peer-social toddler inhibition predicted socially reticent behavior…
