The "mapping" is from concept to concept. For example if there is no concept of collective objects in a spoken language- no way to talk about books for example only a book. Then mapping "we (plural) like books on all subjects" gets to be very hard. The hardware (people) is the same but the conceptual frame works are just too different. Not sure if that was what you were talking about...
