THE EFFECT OF THE AMOUNT OF
VIDEO GAMES PLAYED ON THE
REACTION TIME
 Do Video Game Players have
Faster Reaction Times than Non Players?
 HYPOTHESIS: If the person plays more
Video games, then the Reaction Time of
the Video Game Player will be faster than
the Non Player.
Basic Concepts
 Reaction: Action in response to a stimulus, as of the system or of





a nerve, muscle, etc.
Stimuli: something that incites to action or exertion or quickens
action, feeling, thought, etc.:
Motor Cortex: (region of cerebral cortex) is a term that
describes regions of the cerebral cortex involved in the planning,
control, and execution of voluntary motor functions.
Reaction time: the time that elapses between a stimulus and the
response to it.
Reflex: noting or pertaining to an involuntary response to a
stimulus, the nerve impulse from a receptor being transmitted
inward to a nerve center that in turn transmits it outward to an
effecter.
Perception: Recognition and interpretation of sensory stimuli
based chiefly on memory

Do Video Game Players have Faster Reaction Times than Non Players?
TITLE: The Effect of the Amount of Video Games played on the Reaction Time.
HYPOTHESIS: If the person plays Video games, then the Reaction Time of the Video Game Player will be faster
than the Non Player.
IV: How much time the interviewees play video games a day. (hours)
DV: Dependent variable – Reaction Time (sec)
CONSTANTS: Reaction Test, Age group (12-30), Time of day (12pm to 6pm)
Materials:
·Internet
·Computer/Laptop
·Log Book (To record Data)

1. First I will find individually find 65 Interviewees at school and email or
message them asking them on average how many hours do they play video
games a day.
2. I will then make sure all 65 of the Interviewees have a working
computer/laptop.
3. Then I will give each of them the website to test their reaction.
(http://www.mathsisfun.com/games/reaction-time.html)
4. After that I will record the data in my logbook of their reaction time and
how many hours they played video games a day.
5. I will record their times based on seconds and amount of time they play
video games in hours.
6. After I record the results I will make a chart and my x–axis will be the
amount of time playing video games (hours) and my y-axis will be the
reaction time. (Seconds)
7. I will then analyze the data to check if the amount of video games played
affects the reaction time.

Background Information
 Reaction times can improve if a person keeps
practicing. With more practice the person will
get more use to reacting quickly so the reaction
time has a better chance of improving
 The type of reaction time experiment, type of
stimulus, and stimulus intensity are basic
features of any reaction time experiment, but
there are still many factors affecting reaction
time such as the age of the person and what
time they test their reaction time.
Sources of Error
 The daily activities that someone does such
as baseball, football, basketball can also
affect reaction time.
 Age gap still affects the reaction time (12-30)
 The day where someone tests could also
affect the reaction time.
 Gender might also affect reaction time.
Improvements
 Include physical activities such as sports in
the experiment.
 Reduce the age gap (14-20)
 Gender Specific Results
Extensions/Variations
 The Effect on the amount Daily Physical
Activities spent on the Reaction Time.
 Use a sound reaction test instead of a visual
test.
