Declarative memory and explicit memory are, while similar, quite different. declarative memory not only deals with experiences but also with facts. for instance, you can remember that something has happened (explicit memory and declarative) but you can also remember that something can happen as a recalled fact which is declarative, not explicit. as seperate terms in psychology, declarative and explicit should remain seperate articles on wikipedia, but by all means can each could be mentioned briefly in eachother's artivles to help clarify for some people.
