The purpose of the present study was to examine whether learning in 10-year-old children--that is, the age group for which the Chiviacowsky et al. (2006) study found benefits of self-controlled knowledge of results (KR)--would differ depending on the frequency of feedback they chose. The authors surmised that a relatively high feedback frequency…

Sixteen school-age children with specific language impairment (SLI) and 16 age-matched controls were tested for immediate recall of digits presented visually, auditorily, or audiovisually. Recall tasks compared speaking and pointing response modalities. SLI children showed small recency effects as well as an unusually poor recall when visually…

Twenty children, aged 7-12, with severe visual impairments completed a series of visual tasks requiring interpretation, analysis, manipulation, and visual motor coordination. Findings are discussed in terms of total performance, individual task performance, performance of younger versus older children, and performance of good versus poor readers.…

Presents results of a study of the role of context upon English children's estimation skills. Includes estimation tasks involving distance, area, and volume measurements and children's answers about how they carried out the tasks. Concludes that estimates in contexts perceived as mathematical differed from those involving perceptual-motor skills.…

In two experiments, first and fourth grade subjects performed a speeded card sorting task with either integral or nonintegral dimensions. The dimensions were arranged so that subjects sorted on three types of task: (1) single dimension, (2) correlated dimensions, and (3) orthogonal dimensions. (Author/MS)

The three projects described in this paper were based on the intrinsic connection between language and the structure of perception and action. The first project explored the role of nonverbal frameworks in the development of communication between mother and child, beginning with the first word. It emphasized the role of the mother in the creation…
