To control a possible covariate effect of the independent variable in the analysis (i.e., spatial capability), all the participants were first asked to perform a block rotation test. They were given 10 such questions to complete in 6 minutes. Later, to classify our participants, the base value of 60 (out of 100) of the mental rotation test score was used, as indicated in many related spatial capability studies. A total of 27 participants were assigned to the high-spatial ability group and the others were classified as low-spatial ability individuals in the following analyses.
