Facts about Motor memory

1. 07

   Interference effects in motor memory show that learning two similar skills in close succession can reduce retention of the first skill, a phenomenon called retroactive interference.

   Skill retention after motor memory formation shows a remarkably slow decay rate, with 80% of learned motor skills remaining accessible after 25 years without practice.

   Reaching expert level performance in complex motor tasks like surgery or gymnastics requires approximately 10,000 hours of deliberate practice to establish fully automatized motor memory according to research by psychologist K. Anders Ericsson.
