Final answer:
In a neuroimaging study, brain activity would most likely increase when participants are exposed to a painful stimulus and a negative hypnotic hallucination is suggested. option d is answer
Step-by-step explanation:
In a neuroimaging study where participants are exposed to a painful stimulus and a negative hypnotic hallucination is suggested, the neuroimaging data would most likely reveal that brain activity increases.
This is because the brain would be actively processing and responding to both the painful stimulus and the suggested hallucination. Brain imaging techniques like functional MRI (fMRI) can detect increases in blood flow and neural activity in specific brain regions during different cognitive processes. option d is answer
