Piaget’s (1985) notion of assimilation, children interpret a new situation as similar to what they already know. Cognitive science has made excellent headway on the problem of assimilation, which de- pends on the efficiency with which one assimilates a new instance to an old one. It has produced a number of psychological constructs to help explain how people as- similate information, ranging from feature detection to naive theories to schemas to analogical mapping.
