My hypothesis was that the reaction time of boys would be quicker than the reaction time of girls. The results indicate that this hypothesis should be rejected for girls had a quicker reaction time. Because of the results of this experiment, I wonder if children have a quicker reaction time than adults. If I were to conduct this project again I would test more subjects and build a stronger pipe frame. Stimulus A stimulus is an action or object, which causes you to react.
Some stimuli cause voluntary actions and others cause involuntary actions.
Involuntary An involuntary action is demonstrated when you touch a hot stove. Your action is to pull away, but this action takes no thought. Your sensory cells take it to the spinal cord and it tells the motor nerves, which causes it to pull the hand back. The brain gets the message after the action. Voluntary Voluntary actions are when you want to do something and you think about it first.
