Answer: You have experienced AN IMPLICIT MEMORY TASK
Explanation: Implicit memory is acquired, used unconsciously, and can affect thoughts and behaviours. One of its most common forms is procedural memory, which helps people performing certain tasks without conscious awareness of these previous experiences.
As an operational term, implicit memory refers to effects of previous experience that are shown in tasks that do not require conscious or intentional recollection. These tasks are called implicit or synonymously indirect memory tasks that are contrasted with explicit or direct memory tasks.
