Children 3.5 to 5 years old were asked to judge which of several possible sets of parts matched a configured target form and to copy the target forms. Found a significant association between age and performance on the perception task and consistency across the two tasks. (MDM)

Reports four experiments that examined four-year olds' ability to coordinate orthogonal spatial dimensions. Found that performance was particularly good when two imagined lines of sight were the dimensions to be coordinated. Results support the notion that young children perform better when tasks are set in a meaningful context. (MM)

Examined visual search for compound patterns in 6-, 8-, 10-, and 22-year-olds. Found large improvements with age in search rate for long-range targets; search rate for short-range targets was fairly constant across age. This pattern held regardless of ease of perceptual access to target, supporting the hypothesis of different processes involved at…

A program investigated the feasibility of training selected abilities so as to facilitate transfer among tasks requiring these abilities and thus reduce training time and increase personnel flexibility. An extensive review of relevant literature was a first step in this investigation. Undergraduate college students were used as subjects in an…
