The sentences

a negative trendp = 0.143not close (p > 0.1)

For the MMN component, deviant amplitude showed a negative trend with accuracy (r = −0.308, p = 0.143), suggesting that stronger pre-attentive change detection (more negative MMN) was associated with better task performance.

a positive trendp = 0.151not close (p > 0.1)

The N1 difference wave showed a positive trend with accuracy (r = 0.302, p = 0.151), indicating that larger neural differentiation between conditions (more negative for Different than Same) was weakly associated with better performance.
