Why people experience the verbatim effect
In general, research on the topic suggests that people use two separate but interrelated memory processes:
Gist memory, which focuses on the essential meaning of information.
Verbatim memory, which focuses on the surface form of information.
These two types of memory have separate encoding and retrieval processes, and accordingly, the main reason why people experience the verbatim effect is that in general, gist memory is encoded more effectively than verbatim memory.
