Neuropsychology Practice Test

Frontal lobe dysfunction shows up most clearly when a task requires inhibiting an automatic response and quickly shifting between response rules. The Stroop Color-Word Test taps exactly this combination: you must suppress the automatic tendency to read the word and instead name the ink color, especially when the word and the color conflict. That need to override a dominant habitual response (reading) and to switch to a less automatic rule (color naming) relies on executive control circuits in the frontal lobes. Performance on this task is therefore a sensitive indicator of disruption in inhibition and set-shifting.

The other tests involve frontal processes too, but in different ways. The Wisconsin Card Sorting Test requires discovering and adapting to new rules based on feedback, which measures flexible thinking and problem solving under changing contingencies but not as directly the inhibition of an automatic response. Trail Making Test Part B does involve task switching and processing speed, yet inhibition plays a smaller role. The Tower of Hanoi emphasizes planning and working memory for sequence problems rather than inhibiting a prepotent response or shifting between competing tasks.
