\begin{tabular}{c} \hline \In terms of tools and measures, the studies used a variety of equipment, including eye tracking systems (ETG and ETS), which were mentioned in 16 (95%), making them the most-used tool, while one (5%) study used neuropsychological tests. In terms of study design, most studies used cross-sectional designs (CSD), which were used in 12 (71%) studies, while randomized controlled trials (RCT) were used in two (12%) studies. Single-case designs (SCD) were used in one (6%) study and a between-subjects design was used in two studies (12%).
