Reaction time is the time it takes to process information, more specifically the time interval between a stimulus and reaction. In nature having a short reaction time will increase the animal's chances of survival. A person's reaction time can make he/she more inclined to certain activities such as sports or improve his or her ability to react to indications of danger, such as a fire alarm. In this experiment reaction times will be examined across a group (age, gender, etc) using a web-based reaction test.
What factors influence an individual's reaction time?
- Web-based reaction test. Computer with a fast internet connection. Make sure the computer remains in the same location. Ideally in a quite room with minimal distractions.
- Thermometer – can be provided by school nurse.
- List of instructions for the subjects.
- Microsoft Excel
- Find a computer with a fast, secure internet connection. The computer should stay in one place to eliminate the effects of changing enviornments.
- Determine what factor(s) you would like to examine.
- Recruit your subjects. Find as many individuals as you can. Peers, teachers, parents.
- Male vs. Female – This should be done with males and females around the same age. Ex. 7th graders only.
- Age – Set an age range for a group. Ex. 6-8th graders, teenagers 15-18, Adults 18-25, Adults 26-35, Adults 36-45, etc.
- Athletes – Recruit various sports: basketball, volleyball, baseball teams, etc. Define your «non-athletes» - individuals who do not engage in sports or low physical activity levels.<
- The higher number of data points will increase the validity of your conclusions.
- Create a written set of instructions for the subject. This will ensure that all subjects are given the same amount of information.
- Take the subject's temperature. Always use the same thermometer. Can be provided by the school nurse.
- Have the subject take the reaction test.
- Record the subject's times.
