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., quasiexperimental) 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.
