Graph to show 38 milliseconds difference between predicted and observed slowing in simple reaction times with age

*



Circles and dotted lines are actually observed reaction times in three longitudinal cohorts aged 16-12, 36-44 and 56-63.

Crosses and solid lines show the predicted slowing of simple reaction times across a lifespan of 16-63 years old.

Shorter reaction times correlate with higher general intelligence (IQ) - so this means that actually observed 63 year olds were (38 milliseconds of sRT) more-intelligent than would be expected if they had aged at the expected rate.

Which probably means that the 56-63 year old cohort were significantly more-intelligent than the 16-24 year old cohort, when they were the same age.
