Final answer:
A stroke in the occipital lobe would primarily affect vision, possibly leading to visual perception issues such as loss of vision or trouble with visual recognition.
Step-by-step explanation:
A CVA, or cerebrovascular accident (commonly known as a stroke), occurring in the occipital lobe of the cerebrum would most likely affect vision. The occipital lobe is responsible for seeing, recognizing, and identifying the visual world. Since the occipital lobe is organized retinotopically, it means that there is a direct connection between the position of an object in the visual field and its representation in the brain. Therefore, a stroke in this area may lead to problems with visual perception such as loss of vision, difficulties with visual recognition, or visual field deficits.
