The purpose of the present study is twofold. One is to assess the cultural generality of the information integration rule for moral obligation. The other is to examine how people integrate moral obligation and self-interest. Two studies were implemented following the functional measurement methodology with Chinese samples. Study 1 replicated the results of an American sample on the integration of actor’s obligation and other’s need to assess the cultural generality of information integration rule. Study 2 involved a new test of the integration of actor’s obligation and actor’s need. The result of Study 1 showed that the integration rule of actor’s obligation with other’s need was of an adding-type (i.e., adding or equal weights averaging), which is consistent with previous work with American samples. The results of Study 2 showed that the integration of actor’s obligation and actor’s need follows an adding-type rule.
