Conditions having different superscript letters are significantly different from each other. Those sharing the same superscript are not different from each, based upon Tukey’s post-hoc follow-up tests. Ratings on a 1–6 scale with 1 = ‘not helpful’, 4 = between ‘moderately’ and ‘extremely helpful’ and 6 = ‘extremely helpful’. SD = standard deviation.
