The Subject used was Bowen Sam, a 20-year-old male, 172 cm tall, weighing at 110 lbs. The control condition was having the Subjects’ eyes closed (Fig. 1). The EEG amplitude was the lowest (23 μV), while the Alpha amplitude was 5.19 μV and Alpha rms amplitude was 2.14 μV (Table 1). The frequency during this control condition for the alpha rhythm was 15.38 Hz, which agreed with the expected value of 9-14 Hz (Question B). The following condition was the Subject doing a mental math (Fig. 2). This resulted in the highest amplitudes across EEG (51.4 μV), Alpha (9.32 μV) and Alpha rms (3.29 μV) and the control mean amplitude being much smaller than the experimental mean (Table 1) (Question D and Question E) (Table 2). The highest amplitude of…show more content… The result that opposed what was presented in the Introduction was the control condition, as the amplitudes for alpha and alpha rms were extremely low, when the amplitudes should have been considerably higher (Question F). The differences could be due to environmental variables such as Subject was not alone, but rather in a room full of students. This would have decreased the amplitudes, as the Subject would not be as relaxed due to distraction of others (Question H). In addition the room was fully lit, which could provide visual stimuli and distractions once again that could decrease the amplitude of the alpha and alpha rms due to alpha suppression (Question H). Although, the frequency was close in proximity to 9-14 Hz, it was slightly higher, perhaps due to the environment. Additionally, the condition where the Subject was performing mental math opposed the information given in the Introduction (Question F). That task should result in low amplitudes because it requires concentration, which, results in alpha suppression making it lower. The results however, were opposite with very high amplitudes meaning the Subject was not concentrating on the math problem, but was more in a relaxed state of mind (Question F and…show more content… The lowest amplitudes for alpha and alpha rms and smaller experimental mean seen for the eyes open condition, was expected because seeing visual stimuli would produce alpha suppression, lowering the amplitudes. Listening to music also caused very low amplitudes for alpha and alpha rms, which would indicate that the Subject was concentrated on the music and distracted by it, which could be expected (Question F). In addition, during the recovery from breathing, the experimental mean, alpha and alpha rms were all higher, meaning that the Subject was in a relaxed state. After breathing quickly, one might panic, but regaining breathing would induce a more calming affect, which was seen in the results (Question
