SCIENTIFIC INQUIRY Consider an individual who had beenfluent in American Sign Language before suffering an injuryto his left cerebral hemisphere. After the injury, he could stillunderstand that sign language but could not readily generatesign language that represented his thoughts. Propose twohypotheses that could explain this finding. How might youdistinguish between them?
