In developing grasp and shoulder mobility, what type of practice does moving identical one-pound cans provide?

Moving identical one-pound cans is an example of blocked practice because it involves practicing the same skill repetitively without changing tasks. In this scenario, the individual focuses on moving the one-pound cans, which allows for consistent repetition of the same movements. Blocked practice is particularly effective for developing the initial stages of skill acquisition because it enhances performance through focused repetition, enabling the individual to refine their grasp and shoulder mobility in a controlled manner.

Blocked practice contrasts with other types of practice. For instance, random practice would involve practicing a variety of tasks in a random order, which is more beneficial for transferring skills to different contexts. Massed practice refers to extended sessions of practice without breaks, while distributed practice includes practice sessions interspersed with rest periods, promoting better retention of skills over time.

In this context, the repetitive nature of handling identical one-pound cans directly supports the development of specific grasp and mobility skills, making blocked practice the most applicable choice.
