What does the memory trace refer to in motor learning?

• A. Sensory feedback after movement.
• B. Memory of how a successful attempt feels.
• C. The ability to select and initiate the proper movement.
• D. The motor plan stored in the brain.

Answer: (C)

The memory trace is the signal that helps you select and start the correct movement in response to a cue. It acts as the bridge from decision to action, a mental cue that initiates the motor response and guides the initial part of the movement. With practice this trace becomes stronger and more efficient, so starting the movement happens more quickly and accurately. It isn’t the sensory feedback you receive after you perform the movement, nor the feeling memory of a successful attempt, nor the entire stored motor program or plan. Instead, it’s specifically about initiating the action and getting the right movement started when the cue is present.
