Please read this article about EEG, https://www.frontiersin.org/articles/10.3389/neuro.09.067.2009/full

After reading the article Please answer All the following questions

1. What is the central question being asked in the paper? Is there a specific argument or hypothesis that the paper is interested in proving or disproving? (If so, what is it?)

2. What are the stimuli and/or what is the task used in the paper? How do the stimuli and/or task connect to the main question? (WHY were the stimuli or task chosen over other possible stimuli or tasks?)

3. Who are the participants? Is there anything specific about them that relates to the experimental question? or are they just 18-30 year-old undergrads and grad students in psych? If they are carefully chosen, WHY these subjects and not others?

4. Identify at least one figure that iscentral to the conclusions of the paper and describe what it shows. This figure should present results that address the main question in the paper. What does the plot show? What do the data mean? For example, does the data show a timing difference in mental processes? A difference in the frequency of brain activity for different brain states?

5. What aspects of the methods and/or results give you confidence in the author's conclusions? What aspects of the methods and/or results (if any) give you pause / cause for concern? For example, do you think there are any issues with external validity or reliability? How well/satisfyingly do the experimental manipulations (stimuli, task) match with the big question the paper is trying to address?

6. If this study were to be conducted again, what do you think is the thing you would change first about the paper? Why? (Give your reasons for why the change you want to make is more important than other potential changes - e.g. why subjects and not stimuli changed? Could anything about the protocol be changed to increase external validity?) If you think the paper is generally sound - what follow-up experiment would you do and why?
