Final answer:
Greater drawing deficits are likely if a lesion occurs in the right hemisphere due to its involvement in spatial and nonverbal aspects. However, both hemispheres contribute to function and interact dynamically, with some redundancy between them.
Step-by-step explanation:
Although drawing deficits can arise after lesions to both hemispheres, it is believed to cause greater damage if the lesion is located on the right hemisphere. This is supported by evidence that shows how the hemispheres have different specializations, with the right hemisphere playing a crucial role in nonverbal aspects, such as spatial abilities, facial recognition, and the emotional content of language. Damage to certain areas, like Broca's or Wernicke's areas, found in the left hemisphere can lead to aphasias, which are characterized by loss of language and speech functions. However, it is important to note that there is considerable overlap and redundancy between hemispheric functions, and both hemispheres interact dynamically to produce behavior.
