Final answer:
The ability of gamers to beat difficult levels after a break suggests a memory of motor behavior improves with consolidation, supported by sleep research indicating the role of REM and slow-wave sleep in memory formation and learning.
Step-by-step explanation:
The phenomenon of video gamers finding that they are often able to beat difficult stages after taking a break from the game supports the concept that memory of motor behavior is improved through consolidation. This idea aligns with research related to sleep and cognitive function that indicates a period of rest, particularly sleep, can enhance motor coordination and facilitate the consolidation of memories. Sleep, especially REM sleep and slow-wave sleep, is essential for learning and memory formation.
Furthermore, sleep is associated with the organization of information into long-term memory, therefore aiding in the performance of tasks practiced before sleeping. In the context of a difficult video game stage, the break likely allows the brain to consolidate the motor skills required, leading to improved performance upon returning to the game.
