  Another proposal regarding the generation of intrinsic desires leaves rationality out of the picture entirely. According to this proposal, new intrinsic desires are acquired by associating new states of affairs with ones that already satisfy existing intrinsic desires, according to the principles of reward-based learning. So, if a young child intrinsically desires a dry bottom and a full stomach, and is aware that its mother's presence tends to help with these things, then the young child will naturally desire its mother's presence instrumentally. But whether the child is aware of the instrumental relationship or not, if the mother's presence often presages the satisfaction of the child's intrinsic desires for a dry bottom and full stomach, then the learning processes generated by desire satisfaction will also tend to cause the young child to acquire an intrinsic desire for the presence of its mother (Schroeder 2004).
