Difference in Simple Reaction Time of Young versus Old Adults

Difference in Simple Reaction Time of Young versus Old
Adults Paper
Abstract
•The degree of visual
reaction time is practiced
to assess the processing
levels of cognitive system
as well as, dexterity
between motor and
sensory structures in an
organism.
•The present investigation
involve the 160
respondents where, 100
people were comes under
the age among 18 and 50
years. Furthermore, 50
male and 50 female adults
as well as, information
have been elaborated on
recommended hypothesis.
Introduction
• Investigation indicate that
shorter reaction times could
be inductive of more feasible
outcome.
•However, only in association
with other factors such as
strength, intellect as well as,
motor reflexes. Hence, the aim
of this research is to assess
the impact of age on an
individual’s simple reaction
time in the context of their
visual stimuli (Hodgkins,
2013).

of SRT in Older Group
•Recent research
demonstrates that simple
reaction time is shortest
between individuals who are
less than 20 years of age.
•The key results in this
research examines a greater
intra-individual variability in
the context of SRT in adults.
•In this research, 100
participants would be where
50 were older and 50 were
younger and their age are
between 18 and 50. z-test was
used for quantitative analysis.
The data was analyzed using
Microsoft Excel version 2010.
