Spatial and numerical processing in children with non-verbal learning disabilities.

Consistently with the idea that numbers and space interact with each other, the present paper aimed to investigate the impact of non-verbal learning disabilities (NVLD) on spatial and numerical processing. In order to do so, 15 NVLD and 15 control children were required to perform different spatial (the line bisection and Simon tasks) and numerical tasks (the number bisection, number-to-position and numerical comparison tasks). In every task, NVLD children presented lower accuracy scores than the control group.

Oral health determinants and caries outcome among non-privileged children.

The study aimed at identifying oral health determinants that are present in early childhood, are amenable to change and for which there is evidence of their modulation of the rate of caries progression in a sample of non-privileged children. The null hypothesis was that determinants associated with the child's institutional environment as evidenced by nursery policies significantly influenced the child's oral health. The sample was formed by 2,511 Brazilian 1-5-year-olds.
