Step-by-step explanation:
The process of storing autobiographical information often seems effortless, which is a characteristic of implicit memory. This type of memory involves information about our lives and personal experiences that we can recall without conscious effort. However, when trying to enhance memory for studying or recalling complex information, techniques such as mnemonic devices and active rehearsal can be highly beneficial.
Mnemonic devices are tools that help organize and encode information making it easier to retrieve from long-term memory. For instance, remembering the planets in the order of their distance from the sun can be made easier with the mnemonic 'Mr. VEM J. SUN'.
Rehearsal, especially elaborative rehearsal, is the act of linking new information to existing information, which helps transfer it to long-term memory. Through this process, information is thought about more deeply, making it more meaningful and enabling better retention.
