Additionally, there was a marginally significant interaction effect of Session*Category*Treatment (F (2157) = 3.050, p = 0.054; effect size: η p 2 = 0.035; Greenhouse–Geisser-corrected due to departure from sphericity); with local and historical treatments of ambiguous artworks showing higher scores during retest session (local M = 564.30, SD = 201.43; historical M = 522.26, SD = 179.37) than the baseline, and global and historical treatment of non-ambiguous artworks showing higher scores in the retest session (global M = 537.15, SD = 172.49; historical M = 541.87, SD = 184.97) than the baseline ( Table 1 , Figure 4 and Figure 5 ).
