But there may be a connection: Recoding many bits into one chunk occurs
not only in symbolic codes that are remembered sequentially. It can also
occur in parallel, as we learn to see many parts as one whole. Or even
when we learn to see many things as all one KIND (category) of thing.
This surely involves changes in dimensionality too.

Unless you overlearn the contents of each list of seven, so you know
them forever and all that's needed is a mention of the list-name to
bring them back: In that case. you should be able to remember 7 such
lists of 7. The trick, of course, is in the overlearned chunk. But in
general Miller says nothing about this process of learning and

If you want to pursue Harre further, I will soon have an electronic
