Researchers Have Used Transcranial Magnetic Stimulation (TMS) to Disrupt Portions

Researchers have used transcranial magnetic stimulation (TMS) to disrupt portions of the healthy brain. When asking participants to search for a target, we expect TMS applied to the parietal lobe to

A) have no effect on participants who have not suffered parietal damage.
B) disrupt the search for both a target defined by a single feature (e.g., "Find the red shape") and a target defined by a conjunction of features (e.g., "Find the shape that is red and round") .
C) disrupt the search for a target defined by a single feature (e.g., "Find the red shape") .
D) disrupt the search for a target defined by a conjunction of features (e.g., "Find the shape that is red and round") .
