Question

Quizplus · Accepted Answer

The use of a physiological measure that scans various areas of the brain during a cognitive task suggests the use of a functional MRI (fMRI). An fMRI is a neuroimaging technique that can measure changes in blood flow and oxygenation in active brain areas, providing information about which brain regions are active during different cognitive tasks. The other options, including an electrocardiogram (measures heart rate and rhythm), galvanic skin response (measures sweat gland activity), and cognitive task inventory (measures self-reported cognitive abilities) would not be appropriate measures for assessing brain activity during a cognitive task.
