How quickly do we respond to colors?Featured science projectScience project video

Conclusion

Our hypothesis has been proven to be false. Red color lights do not produce the fastest human response.

 The response time of a driver to an event that occurs on the road is crucial in the prevention of  accidents. A reaction time delayed by a fraction of a second can result in an accident or loss of a life. The response time also differs betwen expected event and unexpected events. Unexpected and surprise events require a longer response time because the driver  needs time to mentally process the event before deciding on the appropriate action to take.

Also consider

To improve the reliability and accuracy of our results, a larger sample of participants should be used.

 

This science fair project may be repeated, by comparing response time between participants of different ages and gender.

Modify the science project experiment, using a dark room and fogged room.
