Mean values of subjective complexity (mean SC) and Spearman’s correlation coefficients (correlations) between SC of real movement or motor imagery of the right hand (RH) or left hand (LH) and the accuracy of classification of brain states during imagination of movements of the left hand compared with right hand (ARLH) in the group of all participants (all), in the group of “pure” right-handers (RHs) and latent left-handers (LHs).
| LH | RH | |||
|---|---|---|---|---|
| Mean SC | Correlations | Mean SC | Correlations | |
| Real movement | All 1.88 | - | All 1.96 | - |
| RHs 1.80 | RHs 0.527 * | RHs 1.87 | - | |
| LHs 2.00 | - | LHs 2.11 | - | |
| Motor imagery | All 2.73 | - | All 2.54 | All 0.697 ** |
| RHs 2.77 | - | RHs 2.40 | RHs 0.664 ** | |
| LHs 2.67 | - | LHs 2.78 | LHs 0.604 (p = 0.085) (0.685 *) | |
The values of correlation coefficients are indicated only in a case of significance. Significant correlations are marked with an asterisk (*) (for p < 0.05) or two asterisks (**) (for p < 0.01), p-value and Pearson correlation coefficients (in parenthesis) are indicated in a case of Spearman trend.
