Two experiments investigated whether poor readers eventually establish a dichotic right ear advantage as predicted by a maturational lag theory. The first studied developmental differences in dichotic listening for normal and poor readers when the order of reporting simultaneously presented items was unconstrained; the second controlled for order…

Subjects aged 8, 10, 12, and 18 years participated in two visual search tasks. (Author/SB)

Examines children's understanding of what variables and relations are important in problem structures, and their use of these variables and relations in problem solving. (HOD)

A study is reported in which subjects aged 8 - 18 years made magnitude estimations of height for targets whose height and distance from them varied. For distances up to 15m, and heights from 5 to 50 cm, size constancy prevailed at all ages. (MS)

In this study of sensitivity to viewpoint, children between the ages of 6 and 14 years were asked to draw an L-shaped array of 3 cubes from 1 of 3 views. At every age, children showed sensitivity to their view in the sense that there were consistent differences between the drawings produced in the three viewing conditions. (SH)

Investigated suppression of activation and retrieval paths to information stored in long-term memory. Subjects were 94 children in grades 1, 3, and 5. Found that the ability to intentionally inhibit the maintenance and recall of irrelevant information improves over the elementary years, and children are less able than adults to withhold production…
