The possible effects of background music on the Uchida-Kraepelin Test, or a continuous adding performance test, were investigated. Subjects were 56 femalecollege students who were devided into 3 groups. Each group performed the Uchida-Kraepelin Test under different conditions; stimulative music and control (Stimulative Group), sedative music and control (Sedative Group), white noise and control (White Noise Group). Major findings are summarized as follows, 1. There was no discernable difference in the effects the 3 types of back ground sounds had on the quantity aspect of additioning performance. 2. In stimulative group and white noise group, the error was lower in the control (no sound) comparing with sedative group; probably due to learning effects. 3. Sedative music might have a decreasing effect on errors.
