People who use methamphetamines chronically perform ______ on the Stroop task
A) much quicker, as their nervous system is on "speed".
B) much more accurately, as their neurons are firing more quickly.
C) poorly, as they have less activity in the frontal lobes and have trouble inhibiting cognitive processes.
D) quite poorly, as they can easily control impulses.
Answer: C
Rationale: Compared to healthy participants, people with a history of abusing methamphetamine have structural abnormalities within the front lobes, which reduced the brain's ability to inhibit both impulsive behavior and irrelevant thoughts. Methamphetamine abusers had greater difficulty with the Stroop task than non-users.
