Repeat the experiment and tabulate the results to make it easier to compare any change in response time.

Make your partner sit down, with his/her forearm resting on the table and extending over the edge of the table. A system made up of nerves and neurons which transfers information to and from different parts of the body. Stimulus → Sensory neuron (convert external stimuli obtained from the external environment into internal electrical impulses – carry information from the sense organs) → Spinal cord/Brain → Motor neuron → Appropriate Response This intriguing experiment tests the time it takes for the brain to process what it is seeing into reacting and taking an action.The nervous system consists of the brain, the spinal cord and nerves which can communicate with each other to co-ordinate all of your actions and reactions . The sequence of events occurring during the time at which the ruler was falling can be summarized in more detail by the following steps: To show the presence of a phenomenon known as muscle memory in which repetition of the experiment should result in a faster response time. Without warning release the ruler making sure that you release the ruler vertically and not horizontally.

Reaction times are known to change with age. Test this by using volunteers of different ages such as for example a 5 year old, a 40 year old and an 80 year old. The muscles in the fingers contract, allowing you to catch the ruler and preventing it from falling on your foot (which can be rather painful). STIMUBALL LTD has been operating for 0 year(s) and 12 month(s). According to the latest confirmation The partner should now be ready to start the experiment, and the partner should once again have their thumb and the index finger on either side of the 0 cm mark. Make sure that their fingers are not touching the ruler.

Test another factor that can affect response time; see if there is a difference between response times when using your non-dominant hand rather than your dominant hand. To understand the concept of reaction time, the time taken for an individual to respond to certain stimuli.
