Fig. 3. Correlations of the PCE with the NCE and GABA in the SMA.

Fig. 3

a,b, higher positive compatibility effect (PCE, subliminal activation) predicts higher (more negative) NCE (subliminal suppression). Further analyses of previously published data [3] also revealed strong correlations between NCE and PCE (experiment 1: r = −0.69, p< .013; experiment 2: r = −0.72, p< 0.008 & experiment 3: r = −0.63, p< .03). Thus it seems a general and robust phenomenon that the magnitudes of the PCE and NCE are correlated across individuals. However, although there is weak correlation in both cohorts between the PCE and GABA concentration in the SMA region (c, d), this was not significant (even across cohorts) and is presumably just mediated by the correlations between NCE and GABA and between NCE and PCE. Thus it appears that the common factor between NCE and PCE does not lie with GABA in the SMA.
