Previous research has shown that children aged 4-5 years, but not 2-3 years, show adult-like interference from a partner when performing a joint task (Milward, Kita, & Apperly, 2014). This raises questions about the cognitive skills involved in the development of such "corepresentation (CR)" of a partner (Sebanz, Knoblich, &…

This is a developmental study of the effects, and role, of imagery in retrieving information from long-term memory. In two blocks of trails, first graders, fourth graders and adults determined whether or not various animals are characterized by various properties, first upon consultation of a visual image and then without imagery.

To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N=245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level…

Three experiments (simple versus choice reaction time, Posner letter identification, and Sternberg memory scanning) attempted to determine whether reliable individual differences in cognitive processing exist in children and, if so, whether these differences are systematically related to age and ability.

Assessed effects of sleep restriction and extension on 9- to 12-year-olds' neurobehavioral functioning. Found that modest sleep restriction led to improved sleep quality but to reduced reported alertness. Children who extended sleep improved significantly from baseline their performance on the digit forward memory test and reaction time on the…
