A 7-month longitudinal study of 20 2- and 3-year-old children shows that children at an early age already know that counting words each refer to a distinct numerosity, although they do not know to which numerosity. It takes children a long time to learn the latter. (SLD)

Forty blind children (ages 6 to 14, IQ's 65 to 132) in residential schools were studied to discover the relationship of verbalism to age, intelligence, experience, and personal adjustment. The children were given 40 selected words to obtain definitions, experience claims, and visually oriented verbalism scores. They then tried to identify items…

A total of 100 3- and 5-year-old children were trained and assessed individually on the concept of equilateral triangle at three levels of attainment: concrete, identity, and classificatory. Five training conditions existed: (1) visual inspection; (2) visual inspection and verbal orienting instruction; (3) visual inspection, free haptic activity,…
