Final answer:
To investigate where value representation occurs in the human brain, functional magnetic resonance imaging (fMRI) can be used. A possible task would involve the subject looking at a photograph and determining if they recognize the person. The fMRI would generate a map of the most active areas in the brain, providing insight into value representation.
Step-by-step explanation:
To investigate where value representation occurs in the human brain, a possible task and method to use is functional magnetic resonance imaging (fMRI). This technique measures changes in brain tissue in response to an experimental condition or event.
For example, the subject could be instructed to perform a visual task where they look at a photograph and determine if it is of someone they recognize. The fMRI would generate a map of the most active areas in the brain, providing insight into where value representation occurs.
