Question ID:PT28 S1 Q23 Passage:Further evidence of a connection between brain physiology and psychological states has recently been uncovered in the form of a correlation between electroencephalograph patterns and characteristic moods. A study showed that participants who suffered from clinical depression exhibited less left frontal lobe activity than right, while, conversely, characteristically good-natured participants exhibited greater left lobe activity. Thus one's general disposition is a result of the activity of one's frontal lobe. Stem:Each of the following, if true, weakens the argument EXCEPT: Correct Answer Choice:AChoice A:Many drugs prescribed to combat clinical depression act by causing increased left lobe activity. Choice B:Excessive sleep, a typical consequence of clinical depression, is known to suppress left lobe activity. Choice C:Frontal lobe activity is not subject to variation the way general disposition is. Choice D:Earlier studies indicated that frontal lobe activity and emotive states are both caused by activity in the brain's limbic system. Choice E:Social interaction of the kind not engaged in by most clinically depressed people is known to stimulate left lobe activity.
