Final answer:
Angie is able to type with near-perfection due to procedural memory, a type of long-term memory responsible for motor skills that operate without conscious awareness.
Step-by-step explanation:
The ability for Angie to type on a computer with near-perfection despite not being able to consciously recall the position of letters on the keyboard is attributed to procedural memory. Procedural memory is a type of long-term memory that is responsible for knowing how to do things, also known as motor skills. It is part of the implicit memory system, which allows us to perform tasks without conscious awareness or effort once they have been learned and mastered.
Examples of procedural memory include riding a bicycle, playing a musical instrument, and typing on a keyboard. Angie's expertise in typing without recalling specific details about the keyboard layout showcases the seamless operation of procedural memory, which is often acquired through repetition and practice and does not require conscious thought to access.
