Reaction Time and Intelligence

  • Arthur R. Jensen
Part of the NATO Conference Series book series (NATOCS, volume 14)


Measurements of various parameters derived from different reaction time (RT) paradigms are found to be correlated with psychometric measurements of general mental ability. Such RT-derived measurements, when combined in a multiple regression equation, predict some 50 percent or more of the variance in IQ or This relationship of IQ or g to RT parameters indicates that our standard IQ tests tap fundamental processes involved in individual differences in specific knowledge, acquired skills, or cultural background.
