Changing technology creates a need for additional computer-related training. A quasi-experimental study tested a theoretical framework that maintained that a playful pre-training software intervention and an individual difference, microcomputer playfulness (MCP), would combine to influence computer-related performance. Results demonstrated that the intervention positively influenced the computer-related learning of low MCP participants more than of high MCP individuals. Implications for computer training are discussed. (Contains 2 tables and and 1 figure.)
