Rhinal cortex (RHI) PMI predicts reduced LDI and LGI for valenced information, but amygdala (AMY) PMI shows no differential relationship between PMI and valence with LDI and LGI performance. (A) RHI PMI predicted reductions in generalization for negative relative to neutral images (maturity × valence: b = −0.051, z = −2.637, P = 0.008) and for positive relative to neutral images (maturity × valence: b = −0.056, z = −2.902, P = 0.004). (B) Amygdala volumetric PMI did not differ between negative versus neutral stimuli for generalization (maturity × valence: b = 0.001, z = 0.087, P = 0.931) or positive versus neutral stimuli for generalization (maturity × valence: b = −0.029, z = −1.733, P = 0.083) behavior.
