Automatic processing and effortful processing are two types of

A) encoding.
B) retrieval.
C) rehearsal.
D) storage.

Automatic processing and effortful processing refer to two different types of encoding, which is the process of converting information into a form that can be stored in memory. Automatic processing is unconscious and requires little to no effort, such as remembering the layout of a room or a phone number through repetition. Effortful processing, on the other hand, requires conscious attention and effort, such as studying for a test or learning a new language. Retrieval refers to the process of accessing stored information, rehearsal refers to the act of repeating information in order to retain it, and storage refers to the retention of information over time.
