What shows your reaction time. (2)

Your brain also helps.

Your brain is involved by modifying and fine tuning flex actions.

Example: When you trip and fall, reflexes automatically command your arms and hands to reach and and break your fall.

What is Reaction Time?

Reaction Time

Reaction time is a measure of how quickly an organism can respond to a particular stimulus.

What shows your reaction time. (1)

Why does your reaction time decrease?

Reflexes have a huge role in reaction time.

What are reflexes?- reflexes are involuntary, or automatic, action that your body does in response to something.

An example is when you tap your knee with a rubber mallet. It sends a signal along a nerve to your spine, A waiting motor neuron sends an automatic command to contract the muscle.

It decreases because the brain processes nerve impulses more slowly, in addition, at old age, one gets slower at performance of acts. Intellectual performance also decreases as one reaches old age.

Question

Things that decrease reaction time.

As you age does your reaction time decrease or increase as you age?

Having a slower than normal reaction time can come with high consequences. Example. While you are driving, and you are doing something while driving, that can cause a higher chance of accidents.

As you age, your reaction time decreases.

Things that can affect reaction time.

age, gender, physical fitness, fatigue, distraction,

alcohol, personality type, and whether the stimulus is auditory or visual.
