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 To show the presence of a phenomenon known as muscle memory in which repetition of the experiment should result in a faster response time. Make your partner sit down, with his/her forearm resting on the table and extending over the edge of the table. STIMUBALL LTD has been operating for 0 year(s) and 12 month(s). According to the latest confirmation

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. 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. Get helpful tips on how to use company credit reports when making potentially critical business choices. Without warning release the ruler making sure that you release the ruler vertically and not horizontally.A system made up of nerves and neurons which transfers information to and from different parts of the body.

Information about the Open Government Licence can be viewed at: http://www.nationalarchives.gov.uk/doc/open-government-licence/version/2/ 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). To understand the concept of reaction time, the time taken for an individual to respond to certain stimuli.The sequence of events occurring during the time at which the ruler was falling can be summarized in more detail by the following steps: 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 . Repeat the experiment and tabulate the results to make it easier to compare any change in response time. This intriguing experiment tests the time it takes for the brain to process what it is seeing into reacting and taking an action.
