Reaction Time Lab Report
How does the
body position
of a person effect their
reaction time
?

By Anwar, Henry, Kevin, Teja
If a person was in a sitting position, then they would react faster because their movements would not be restricted.
Hypothesis
Refuted by data
Experiment Design
Procedure
Materials
1. Start up laptop, search for 'RED LIGHT - GREEN LIGHT Reaction Time Test'

2. Have test subject in a sitting position on a chair/stool within reachable range of the laptop

3. Start the test by pressing any key on laptop

4. Have test subject press as soon as they see the green light

5. Have them repeat step 4 for 5 trials

6. Calculate average & record data in table

7. Change the person's position to prone and repeat steps 2-6

8. Change the person's position to standing and repeat steps 2-6
Laptop w/ internet access
table
paper & pencil
chair/stool
Variables
Controlled: Test (Red Light Green Light), testing method, laptop, premises

Manipulated: Body position

Responding: Reaction Time in seconds
Driving Question:
Purpose
To determine whether the body position of a person has an influence that will change their reaction time
Importance:
Gather useful information
Gain knowledge of reactions
Data & Observations
Conclusion
Time is Ticking...
In conclusion, our hypothesis was refuted by the data because it showed no differences in reaction times in relation of body positions.

So... why is this information important?
Reaction Times:
can be a matter of life or death
can help with sports/ daily activities.
can also get you certain jobs.
Research
No previous research, data, or lab report found

New Questions:
-How do drugs affect reaction time?
-How does the potency of drugs affect reaction time?
