Potter (1990) stated that long-term memory may have three forms corresponding to the three forms of short-term memory. The dominant form of long-term encoding is conceptual, but visual and auditory long-term memories are also available. One implication of this conception of memory is that the extremely limited capacity of short-term memory implies that we should limit the number of chunks to be associated at any one time to three or four and that these not be redundant, because the short-term conceptual and verbal buffers are so vulnerable to interference. There is no reason to believe that information stored in any of one of the three short-term memories is more likely to be remembered because it was in that memory.
