Figure 1.
Diagram of the predicted relations.
This graph shows the predicted constructs of the SNARC effect according to the account of the spatial mental number line. The connectors show the tested correlations (non-predicted relations are shown with dashed lines).
Table 1.
Experimental design. Each session began with a parity task, followed by a comparison task (Session1), or two mental rotation tasks (Session2).
Figure 2.
Split-half reliability of the SNARC effect.
This graph shows the scatterplot of the correlation between the amplitudes of the SNARC effect computed from two halves of the trials, and the corresponding regression line.
Figure 3.
Test-retest reliability of the SNARC effect.
This graph shows the scatterplot of the correlation between the amplitudes of the SNARC effect computed from the two experimental sessions, and the corresponding regression line.
Figure 4.
Correlation between the SNARC and the distance effect.
This graph shows the scatterplot of the correlation between the mean amplitudes of the SNARC effect and the amplitude of the distance effect, and the corresponding regression line.
Figure 5.
Correlation between the SNARC effect and the 2D Mental Rotation.
This graph shows the scatterplot of the correlation between the mean amplitudes of the SNARC effect and the amplitude of the angle effect observed in the 2D mental rotation task, and the corresponding regression line.
