I did implicit versus explicit memory, recollection versus familiarity, semantics versus episodic memory, memory and short-term memory versus long-term memory.
Forth, Semantics. Because meaning is at the core of human communication, the study of semantics cuts across all of the other levels thus far discussed.
A promising semantic theory along this line of thinking nowadays is COGNITIVE SEMANTICS, though it is really a cluster of many partially overlapping approaches to semantics than a single well - defined theory.
It differs from the kinds of meaning we studied in semantics in that its interpretation depends more on who the speaker of the sentence is, who the hearer is, when and where it is used.
