Evaluates preschoolers' ability to distinguish left-right mirror-images of objects on a memory task and ability to name rows of objects on a page in a consistent lateral direction. Abilities were assessed first without specific instructions on the relevance of left-right information and then with instructions. (Author/AS)

A study of 300 children in kindergarten, grade 2, and grade 6 found that background music improved visual discrimination task performance at the youngest and middle ages and had no effect on the oldest participants. On a square identification task, background music had no influence on easy and difficult tasks but lowered performance on…

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.…

Reports the results of two experiments dealing with children's visual and tactual performance. In the first task, after several presentations of a series, the tactual group made almost errorless discriminations. But with memory demands, tactual performance became poorer than visual performance. Found a large developmental difference. (JAC)

Investigated the maintenance and generalization of Individual Education Program (IEP) objectives. Comparison groups and 25 children with mental retardation from early intervention programs completed previously achieved and closely related tasks pertaining to color, shape, number, and size. Found variability in maintenance and generalization for…

The few studies concentrating on adult age changes in discrimination shift behavior have reported that the performance of elderly adults on such tasks is inferior to that of younger adults and, in fact, similar to that of children. To determine whether verbal labeling, which has facilitated the performance of young children, would also reduce age…
