The purpose of this study was to investigate the effects of active rest on the speed atwhich mental arithmetic can be performed. A mental arithmetic board similar to the Uchida-Kraepelin psychodiagnostic test was used for this study. Three groups were compared to determine the effect on working speed. (I) Group 1 wasthe passive rest group. After performing an initial mental addition (pre-test), the participantsin this group took 5 minutes rest whereby they closed their eyes and remained quiet andimmediately after, they did the mental addition (post-test). (II) Group 2 was the active restgroup. After performinig an initial mental addition (pre-test), the participants in this groupperformed tapped with the right hands for three minutes and immediately after they did themental addition (post-test). (III) Group 3 was active rest plus passive rest group. Afterperforming an initial mental addition (pre-test), the participants in this group performedtapped with the right hands for three minutes. After that, they took 2 minutes rest andimmediately after, they did the mental addition (post-test). The result showed that the rest effects to perform mental addition was the highest ingroup 3, followed by group 1 and finally group 2. This result of the rest effects was investigated to determine the interaction betweenlearning effects and mental fatigue.
