Table 2 The loadings of each original variable on the identified latent constructs are presented. Exploratory factor analysis (EFA) was performed for the total scores of the cognitive tests, while independent component analysis (ICA) was used for the error scores. Loadings with absolute values greater than 0.3 are highlighted in bold.
