Which kind of psychological researcher would be most interested in the research question, "do people who lose most of their cerebral cortex in an accident still exhibit signs of consciousness? "?

A cognitive neuroscientist.

Explanation:

Cognitive neuroscience is a field of study shared between medicine and psychology, which aims to understand which brain processes and areas are involved in cognition, that is, the psychological process through which we construct our knowledge and understanding of the world. In this case, a cognitive neuroscientist would be interested in how a biological and medical event involving the brain (losing most of the cerebral cortex) affects the psychological processes (showing signs consciousness or not). Cognitive neuroscience is still a relatively new field of study.
