Step-by-step explanation:
The time frame used for expanding gap repetition is typically referred to as the spacing effect. It is a cognitive phenomenon in which information is better remembered when it is repeated over spaced intervals of time rather than all at once.
For example, let's say you're studying for a psychology exam. Instead of cramming all the information in one study session, it would be more effective to space out your study sessions over a few days or weeks. This allows for better retention and long-term memory.
The spacing effect has been studied and proven in psychology, which is the subject relevant to this question. It is a concept applicable to learning and memory in general, making it an important topic to understand in the field of psychology.
