Cognitive load theory (CLT) distinguishes three types of cognitive loads: intrinsic, extraneous, and germane, of which the latter is generally imposed in learning activities. To examine the nature of germane cognitive load, the participants engaged in 8-by-8 Reversi games against computerized opponents. The experimental results indicated that germane load decreases as extraneous load increases because the cognitive resources for assigning the germane load are exhausted by the extraneous load, and that there are two types of germane load: one that increases with an increase in intrinsic load and the other increases as intrinsic load decreases.
