Which of the following is true about massed practice?

Massed practice involves continuous practice of a skill with relatively short rest intervals in between. This approach emphasizes the repetition of the same task or skill over an extended period without significant breaks, which is effective for promoting muscle memory and skill proficiency in various activities. The structure of massed practice leads to high levels of engagement and allows for substantial practice time, which is beneficial for improving performance in the skill being learned.

The other options do not accurately represent massed practice. Longer rest periods are characteristic of distributed practice, which contrasts with the continuous nature of massed practice. While massed practice can be used for motor skills, it is not limited to them, as it can also apply to cognitive tasks, making the focus solely on motor skills inaccurate. Lastly, massed practice is not classified as a cognitive learning method as it primarily emphasizes physical skill acquisition rather than cognitive strategies.
