The primary role of the occipital lobe is centered around visual processing. Located at the back of the brain, this lobe is primarily responsible for interpreting visual information received from the eyes. It decodes various aspects of vision, including color, shape, and motion. The occipital lobe is equipped with specialized areas, such as the primary visual cortex, which is crucial for recognizing and interpreting visual stimuli. This capability makes it integral to our perception of the surrounding world, allowing us to form a comprehensive visual experience.

In contrast, sensory integration involves multiple brain regions working together to process various sensory inputs, not just limited to vision. Language comprehension is primarily associated with the temporal lobe, particularly areas like Broca's and Wernicke's areas, which manage different aspects of language processing. Affective response pertains to emotional reactions and is mainly regulated by structures such as the limbic system, which includes the amygdala and hippocampus, rather than the occipital lobe. Thus, the role of the occipital lobe is distinctly focused on processing visual information, making it the correct answer for this question.
