Which aspect of development focuses on the small, precise actions of the hands and fingers?

Fine motor coordination specifically refers to the ability to perform small, precise movements using the hands and fingers. This skill is essential for tasks that require a high level of control and dexterity, such as writing, buttoning shirts, or using tools. Fine motor skills are developed through activities that promote hand-eye coordination, finger strength, and precision, making them critical for everyday functioning and various learning processes.

In contrast, gross motor coordination involves larger muscle movements that affect the torso and limbs, such as running or jumping, and is not concerned with fine, detailed manipulations. Physical development encompasses a broader range of growth and changes in the body, including both gross and fine motor skills, but does not specifically highlight the intricate movements of the hands and fingers. While motor skills is a term that includes both gross and fine motor functions, it does not specify the precise fine motor actions that are the focus of the question. Thus, fine motor coordination is the most accurate answer in this context.
