The book may explore the role of memory in learning, highlighting the importance of encoding, storage, and retrieval of information.

C. Memory Systems: From Sensory to Long-Term Memory

Different memory systems, including sensory memory, short-term memory, and long-term memory, are likely explained. The various types of long-term memory, such as episodic, semantic, and procedural memory, are probably distinguished. The processes of encoding, storage, and retrieval are explored, along with factors that influence memory, such as interference and decay. Memory distortions and the fallibility of memory are likely also addressed.
