Final answer:
Implicit memory is a type of long-term memory that is not consciously retrieved but is evident in task performance. It involves skills and routines that are learned without our awareness and are not remembered through conscious effort.
Step-by-step explanation:
The type of memory that is not stored as a file that can be retrieved by searching alphabetically is known as implicit memory. Implicit memories are long-term memories that do not enter our consciousness and are learned without our awareness. Such memories cannot be consciously recalled but are evident in our performance of tasks. For instance, the ability to ride a bicycle or tie shoelaces after years without practice illustrates implicit memory at work. While you may not be able to outline every step in the process, your body retains the skill. This kind of memory operates behind the scenes, shaping actions and behaviors based on experiences we may not even remember.
