Order Descriptioncite actual research studies — cite empirical papers not theoretical ones
definitely cite some of the empirical papers we’ve read for class( materials is attached) — your recommendation must connect to the content we’ve covered in class (or will cover in class)
you may also cite a study that was discussed in a PPT presentation from class, though I would encourage you to find the original paper and at least skim through it to make sure you are describing the study & findings accurately
if you’re having trouble finding 3 sources for your recommendation, you may cite a few empirical pieces that are NOT specifically from class (you might get some ideas from the many empirical studies that were cited in review papers like Barsalou, 2008, for example)
