Inspection time tasks directly measure the amount of time that a stimulus must be present before the brain can notice that stimulus. Nerve conduction velocity tasks measure the speed at which nerves transmit signals, and reaction time tasks measure the time it takes to respond to a stimulus after it has been noticed. Therefore, choices A and C are incorrect. Choice E is also incorrect, as not all three types of tasks measure the same thing.
