What is forward inference?

What is forward inference?

• A. Assuming a brain region maps to a single mental process.
• B. Inferring mental state from observed brain activity.
• C. Drawing conclusions from a known stimulus to patterns of brain activity.
• D. None of the above.

Answer: (C)

Forward inference is about predicting brain activity starting from the presented stimulus. It involves encoding models that map features of a known stimulus or task to the measured brain responses, such as predicting how a visual scene will evoke patterns of fMRI activity in the visual cortex. This is different from trying to read out mental states from brain activity (inverse inference). The described option fits forward inference precisely: drawing conclusions about brain patterns given a known stimulus.
