The present study examined the effect of the token economy on clean-up behavior among family members. We conducted experiments with one family (1 man and 3 women), in which the family members consented to the introduction of the token economy. The introduction of the token economy among family members (experiment 1) and the new physical environmental setting that introduced a display shelf for cloths (experiment 2) resulted in an increase in clean-up behavior as a household task. The goods and cloths left in the living room of the home were put in the storage space. In other words, the results demonstrated the effectiveness of the token economy and the new physical environmental setting (introducing a display shelf for cloths).
