The hypothesis of this paper predicts if low-intensity electric and magnetic fields (EMF) are a method of sensory transduction, then it is expected that that EMF can evoke brain potentials like other sensory modalities. This hypothesis can be found at the end of the Abstract and at the end of the second to last paragraph in the Introduction.
(2) Is the writer’s voice passive or active and does he appear in the text? If the writer appears, how and where in the paper does this occur?
The writer has both passive and active voice present throughout the text. The writer does appear throughout the paper in active voice in the Abstract, fourth line “ We tested this hypothesis by …show more content…
He also used paired t-test for more accurate results. Additionally, he also compared and curved the percentage recurrence R(t) versus Time (s) to compare the field onset. The writer also uses bar graphs to illustrate the results obtained on Onset and Offset respectively of magnetosensory evoked potentials (MEPs), which were used to measure occipital electrodes. Furthermore, the write also uses bar graphs to illustrate onset and offset respectively of magnetosensory potentials which measured from the central and parietal electrodes. Lastly, the write also uses line graphs and curves to portray the onset auditory evoked potentials that were used to detect time averaging and recurrence analysis. Thus, the write uses a variety of line graphs and curves along with bar graphs to provide clear but valid presentation of data to the reader.
(5) In which sections does the writer cite references? Are all of these references found in the bibliography? Which is the oldest reference?
The writer cites references in the Introduction, Experimental procedures, and Discussion. All references are found in the bibliography. The oldest reference is referenced by Frey AH in 1962 for Human Auditory Systems Response to Modulated.

(6) How many entries are listed in the bibliography? Is every one of these reference directly cited in the paper? Why is this an appropriate number of references?
There are 45 entries listed in the bibliography and everyone of these reference is directly cited in the paper. This is an appropriate number of references because it portrays that the write did extensive research that was relevant to his topic and main objectives as it is important to have enough backup information and older studies that are related and can support the writer’s main idea and hypothesis, but it is also important to select the most relevant references that will not only support the writer’s main idea but also strengthen his results.
(7) Could you follow the Materials and Methods section and complete the experiment yourself? Why or why not? What if you did have the equipment and time available?
Yes, if I was given the equipment and time available I believe that I could follow the Materials and Methods section and complete the experiment on my own and perhaps with the help of some team members to make the procedures easier and faster. The writer is very specific and detailed in how they went about doing the experiment such as how many subjects were involve, the specific kind of function generator used and amplifier. He even mentions the measurements of the coil currents and explains and describes the where the subjects sat and what was the ambiance
