Alexandra believes that the effects of attention on perception occur very quickly on a fine temporal scale. Which of the following techniques should she use to investigate the changes in perceptual processing that may accompany focused attention?
A)CT (computerized tomography)
B)PET (positron emission tomography)
C)MEG (magnetoencephalography)
D)MRI (magnetic resonance imaging)

Question

Quizplus · Accepted Answer

MEG is the best choice for investigating the changes in perceptual processing that occur very quickly on a fine temporal scale. This technique measures the magnetic fields generated by neural activity, which allows for high temporal resolution (in the millisecond range) and good spatial resolution. PET and MRI have lower temporal resolution, and CT has poor spatial resolution.
