1. When discussing Immediate Memory Span (Miller's name for Working/Short-term memory), Miller notes that it is the number of items, not their complexity, that determines how much you can remember. For example, you can remember the same amount of words as you can numbers, even though words are more complex. Why do you think we are limited more in terms of "number of things" as opposed to complexity?

2. In his concluding paragraph, Miller notes several other appearances of the magical number 7, both in historical/cultural phenomena, as wel as in other fields of psychology. Miller's conclusion is that these things are probably coincidental, but what do you think? Is there any reason to think these things might be limited or influenced by our working memory capacity?
