What does "reaches" entail in the context of motor skills?

In the context of motor skills, "reaches" refers to the ability to effectively extend the arm in a controlled manner to grasp or place objects. This definition encompasses not only the physical action of reaching but also the purpose and function behind it — that is, achieving a goal or completing an activity by manipulating objects within one's environment.

Reaching is not just about extending the arm; it involves coordination, timing, and the ability to adjust one’s grip and positioning to successfully interact with objects. This action is fundamental in various daily activities, such as when a person reaches for a cup, pulls a door open, or places items on a shelf. Effectiveness in reaching also considers the ability to maintain a stable posture while extending the arm, which enhances not only the success of the task but also safety and efficiency.

While other options may describe aspects of reaching, they do not encapsulate the essential goal-directed nature of the movement as highlighted in the correct choice. For instance, extending the arm without bending the trunk might describe a physical maneuver but does not encompass the broader functional context. Similarly, stretching into awkward positions or maximizing distance in a rigid posture suggests less functional and often less safe methods of reaching that do not reflect the intended meaning within motor skills development.
