A wide-ranging psychologist. This is the same George Miller whose analysis of Zipf’s law was mentioned in Section 3.2. He is perhaps most famous for his “human information processing” analyses of cognition, such as the limit of 7 ± 2 on the number of “chunks” that can be retained in short-term memory [Miller, 1956]. The same information-theoretic motivation underlies all these wide-ranging efforts.
