Tracy took tennis lessons when she was very young but had not played tennis for years when she decided to enroll in a tennis class at college. A moment after she picked up her racket, she realized with surprise that she had shifted it to the correct forehand grip without even thinking. Tracy's memory made this possible.

OPTIONS:

A) implicit

B) psychomotor

C) episodic

D) semantic

A) implicit

Explanation:

Implicit memory is a type of long-term memory in humans that can also be referred to as unconscious memory or automatic memory, which is acquired and used unconsciously. Implicit memory enables an individual to be able to use past or old memories of previous experience that have been acquired to be used especially in performing a task without consciously thinking about them.

Tracy’s ability to still pick up her racket and shifting it to the correct forehand grip without even thinking is made possible by her implicit memory.

Another example of implicit memory is our ability to sing a song we are familiar with, even without having to think about them. Riding a bike is another example.
