For the lowest IQ participants, performance was near floor for all three age groups.

That tends to be around 0.275 second.
Why do old people have slow reactions?
Reflexes and age Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time. But the effect of age on reflexes and reaction time varies greatly from person to person.
What foods help with reaction time?
Vitamin-rich foods like broccoli, kale, and spinach are said to improve overall brain function. These small changes to your diet can have a profound effect on your reaction times. When your brain is able to reach peak performance levels, it’s able to send off signals at incredibly fast speeds.
