The two have different speeds with speed of light

The objective of
these tests was to understand the reaction time and determine if there is a
difference in reaction time among individuals using eye-hand coordination
exercises. From the results obtained, it is evident that there exists precise
coordination between the eye and the hand control, as stated by Johansson et
al., (2001). The results also prove that different individuals have different
reaction times. This is in agreement with Balakrishnan
et al., (2014) research. This is because eye-hand coordinated processes are mental
activities and different individuals have different neural mechanisms. The
difference in results obtained using the two tests owed to various factors like
distance, ease of moving the hand, and precise seeing. Light from the machine
is bright and can easily be detected as opposed to seeing the instance in which
the ruler falls.

Besides, the two
have different speeds with speed of light being very high as opposed to that of
a falling ruler that depends on its weight and force of gravity. This, in
essence, will lead to a prolonged reaction time as compared to the machine
test. Also, it was easier to click a button ON and OFF as opposed to catching
and releasing.  This is because the
choice of reaction time is dependent on the movement of the device (Balakrishnan et al., 2014).

In future, this experiment should incorporate more
considerations like taking both right handed and left handed dominant
individuals. Besides, it can be broadened by making an individual of different
ages, gender, as well as various body status, for instance, relaxed and
fatigued body. Besides, the number of trials could be added from three to maybe
ten, to assess the change as one is getting used to the stimulus. This exposes
the student to more opportunities for learning and assimilating with the
physical activities.


An individual’s
reaction time depends on his “mental processing time, device response time,
nerve conduction time, and movement time” (Balakrishnan et al., 2014). This, in essence,
means that different individuals will have the distinct reaction time to a
visual stimulus or rather any form of stimulus. However, if the same individual
is exposed two different visual stimuli, the reaction time will differ. This is
because the choice of reaction time is dependent on device response and
movement time. Though the investigation was only on males of almost equal age,
the results predict a clear correlation in eye-hand coordinated responses. The
hand will respond once the eyes have seen the stimulus. This is not only
important in learning but also there outside especially when driving. Also, the
results points to varying reaction time depending on the test
