An experimental research article was classified as having used a ‘‘within-subject’’ design if each participant (or group) was exposed to all experimental and control conditions, and data were analyzed across conditions for each participant (or group). ‘‘Between-group’’ design was recorded when comparisons were made between groups of participants who were exposed to different conditions. Designs with and without randomization procedures (i.e., quasi experimental) were included in the between-group classification. If inferential statistics (e.g., ANOVA, ANCOVA, etc.) were used to analyze the data for within-subject or between group designs, the name of that test was recorded.
