Final answer:
Motor skills and working memory are the primary processors activated when writing with the right hand, as they manage the coordination of fine motor movements and the integration of sensory inputs and past experiences necessary for writing.
Step-by-step explanation:
When considering the activity of writing with the right hand, motor skills are most clearly being activated. This physical activity relies heavily on the nervous system and motor cortex, coordinating the fine motor movements needed to write. Furthermore, understanding which processor or processors were activated in this activity involves acknowledging the sensory stimuli from the act of writing being registered, processed, and relayed through the central nervous system (CNS).
To perform the act of writing, initial sensory input registered through receptor cells is necessary, followed by the associative processing and integration in multimodal areas of the cortex. These processes culminate in a motor response, managed by different cortical areas responsible for coordinating the hand's movements.
In addition to motor skills, working memory—which includes the integration of sensory input with past experiences and knowledge to perform the task at hand—would be involved as you recall how to form letters and maintain the flow of writing. Another potential area activated could be the sensory register, considering the input of tactile feedback as the hand moves across the page. However, since writing with the hand is primarily a motoric activity, the motor skills and working memory are the primary processors activated in the task of writing with the right hand.
