Time pressure and caffeine differentially affected the performance of introverts on verbal ability tests similar to the Graduate Record Examination. With time pressure and 200 milligrams of caffeine, the performance of introverts fell by 0.63 standard deviation, but extroverts by 0.44 standard deviation.This publication has 10 references indexed in Scilit:
