Results indicated that average reaction times for the auditory and visual stimuli tests were both significantly different from that of the control conditions (see table 1 and figures 1, 2 and 3). Differences in average reaction time differing from the control test (test 1) range from as little as 4 milliseconds (test 2, test subject 2) to that of 67 milliseconds (test 4, test subject 3) (see table 1 and figure 1, 2 and 1.3). According to the averages of the percent increase in reaction time, the combined auditory and visual condition (test 4) had the greatest percentage increase within each individual subject, followed by visual stimuli and then auditory. It is evident, throughout the results documented, that all test subjects experienced an increase in reaction time, that is, the time taken to respond to the on-screen colour change, when external stimuli were present (see table 1 and figures 1, 2, 3, 4, 5, 6, 7, 8 and 9). The largest average increase in reaction time when incorporated with only one stimuli was documented in Test 3 (visual stimuli) with a 26% increase in reaction time by Test subject 4 when completing the test with visual stimuli (see figure 1.4). Visual stimuli, in comparison to auditory stimuli, had a greater effect on the reaction time of individuals (see figures 1.4 and 1.5). However, the difference in averages was not significant (Figure 2). This could be due to subjects that had particularly low reaction times during the music condition, yet still had…
