Abstract
The purpose of this study is to activate the disposition behaviour of dealing with the recyclable clothes by using the primary causes related to the behaviour. The summary of the outcome of this research is as follows. First. the attitude of girl students toward the consumption of their clothes is of great value. It presents the attitudes toward both the internal incentive and the external incentive are of great value and the attitude toward the external incentive has a little higher level than the attitude toward the internal incentive does : the altruistic behaviour of high school girls who tend to simply give or donate their clothes to their relatives or neighbors has a higher level than the economic behaviour by barter or sale at second-hand. Second. there's a positive correlation between the attitude toward the consumption of clothes and the altruistic behaviour in dealing with clothes and there is not a significant correlation between the attitude toward the consumption of clothes and the economic behaviour. The attitude toward the internal incentive has a positive correlation with the altruistic disposition. This research shows that there's a positive correlation between the attitude toward the external incentive and the economic disposition behaviour and the altruistic disposition behaviour. Third. the relative power of influence of the related variables that have an effect on the altruistic disposition behaviour shows that the attitude toward the internal incentive comes first and the personal contact with the information comes second. the attitude toward the consumption of clothes comes third and the existence of mother's job comes last in order of influence. The relative power of influence of the related variables that have an effect on the economic disposition behaviour shows that grades and the attitude toward the external incentive comes first and the existence of siblings comes next in order of influence.
