Dienes and Berry (1997) argue that there really are two kinds of knowl
edge, implicit and explicit, that can be characterized through a subje
ctive threshold. We argue that the subjective threshold does not separ
ate two forms of knowledge, but instead two uses of knowledge, for two
different purposes. With Neal and Hesketh (1997), we suggest that an
understanding of learning will be better served by investigating the p
rocessing that occurs under various circumstances than by attempting t
o isolate learning that occurs with awareness from that which occurs w
ithout it.
