Question
Posner mentions event-related electrical potentials measured from electrodes on the scalp (EEG studies). Example findings include: Need one answer only
Question 4 options:
visual stimuli evoke scalp responses in the primary visual cortex but did not cause scalp responses in any other areas of the brain and movement evokes scalp responses in the autonomic nervous system throughout the body
scalp recorded potentials arose in the temporal cortex when subjects were exposed to images of bikes and the occipital lobe produced event-related potentials when subjects were shown humorous videos
visual stimuli evoke scalp responses in the primary visual cortex at 60 milliseconds, followed by positive and negative voltage changes in nearby visual areas and movement evokes scalp responses in the frontal cortex
movement evokes scalp responses in the frontal cortex, visual motor cortex, and basal ganglia, whereas latent reaction times were correlated with shorter event-related potentials

movement evokes scalp responses in the frontal cortex, visual motor cortex, and basal ganglia, whereas latent reaction times were correlated with shorter event-related potentials
Explanation / Answer
The correct answer is Option D. Movement evokes scalp responses in the frontal cortex, visual motor cortex, and basal ganglia, whereas latent reaction times were correlated with shorter event-related potentials.
