Final answer:
Anita's inability to recognize faces after a right hemisphere brain injury is attributable to the lateralization of brain functions, where the right hemisphere oversees face recognition and nonverbal processing.
Step-by-step explanation:
The theory of lateralization can explain Anita's condition in which she can no longer recognize faces after a right hemisphere brain injury. The right hemisphere is often associated with nonverbal processing, which includes the recognition of faces, a function known as prosopagnosia when lost. Moreover, the right hemisphere is known for its role in processing visual and spatial information, understanding figurative speech, and perceiving emotions. In Anita's case, the injury to her right hemisphere disrupted her neural circuits responsible for the complex process of face recognition.
From the reference information, we also learn that the right hemisphere controls the opposite side of the body and is involved in various behavioral and cognitive functions. Damage to the right hemisphere can affect language in regards to its nonverbal aspects such as facial expressions and body language, as well as understanding figurative aspects of speech. These points further underline the significance of the right hemisphere in cognitive and perceptual tasks.
