In this research project, the problems studied were as follows: (1) Are there differences in scanning patterns between preschool children who show Positional Response Sets (PRS) and normal adults? (2) Do the techniques utilized in "An Exploration of PRS in Disadvantaged children and a Technique for Reduction of Such Sets" change scanning patterns? and, (3) Do these techniques change PRS behavior as was shown in previous work? The subjects (40 preschool children from low-income areas of New York City) were shown a quadrant Chinese letter array, and eye movement patterns were monitored by an Eye Movement Recorder. Subjects were then given training in a technique designed to encourage scanning through entire arrays. Following training, subjects were again recorded as to eye movement patterns and retested on the Chinese Letter Naming Task. In terms of directly changing scanning behavior, evidence of the efficacy of the training procedure is absent. Whether or not training procedures similar to the one used here can produce changes in scanning remains to be seen.
