A patient produces fluent, sensible-sounding speech but cannot understand what others say. This pattern points to damage in:

1. The chapter contrasts the two language areas directly by the deficit each produces. 2. Wernicke's area sits in the temporal lobe and is important for speech comprehension. 3. People with damage there can produce sensible language but are unable to understand it, which matches the patient described. 4. Damage to Broca's area produces the opposite pattern, great difficulty producing language of any form, as in the case of the engineer who could read but could no longer speak or write. _Source: OpenStax Psychology (1st ed., CC BY 4.0), Ch 3 "Biopsychology", §3.4 The Brain and Spinal Cord_
