This report documents a computer-based gaming system for assessing recognition performance (RECOG). The game management system is programmed in a modular manner to: instruct the student on how to play the game, retrieve and display individual images, keep track of how well individuals play and provide them feedback, and link these components by supervising routines in order to execute the game. This modularity in programming, together with the game management system's independence of any graphic database (e.g., aircraft or ship silhouettes, human anatomy, topography, electronic circuits), contributes to its generalizability. The game, then, provides a set of software tools which can be used by others who want to assess recognition performance. The software for the complete gaming system is currently on three floppy disks which control the play of the game, contain the graphic-images database, and maintain records of individuals' recognition performances. The game itself is run with two dual-density disks on the Terak microcomputer employing two drives. It is implemented on the UCSD P-System and written in UCSD PASCAL. The program listing is included in Appendix A. (Author/BW)
