Pros: experience on campus with professors
Cons: relying on fund-raisers to go on psych conventions
In my position as an unpaid student researcher, I got exactly what I expected: time with people who knew their skills and were willing to teach me. In my work, we logged in when we arrived at the work station and began training, or entering data, or teaching students, and continued donating the hours we promised until the end of the day when we'd neatly pack up.
I learned how to create master codes, work Microsoft Excel, schedule testing sites and days, recruit participants, how critical it is to train researchers in the same study, what attending a psychological convention entails, and working under stressful deadlines.
The hardest part of the job was pinning down time to learn the complex formulas needed to write the results of the article. The most enjoyable part of the job was entering the data and keeping everything in its place.
