An Investigation of the Feasibility of a Video Game System for Developing Scanning and Selection Skills

This study examined the effectiveness of a microcomputer-operated video-game format in training nonvocal students with severe physical handicaps to make scan and selection responses similar to those needed for operating linear scanning augmentative communication aids. The video scanning and selection game systematically shaped scanning on more complex screens by slowly increasing the number of boxes presented simultaneously on the screen (i.e., from one to three boxes). Three children participated in a multiple probe across-subjects design to evaluate the effectiveness of the video game. Results indicated that all three children showed substantial increases in the number of correct scan and selection responses made at all three levels of difficulty. Generalization data indicated that all three children were able to transfer use of the skill to a Zygo 100 communication device. Maintenance of the effects also was demonstrated.
