Negativity bias for sad faces in depression: An event-related potential study

Highlights • Patients with major depressive disorder (MDD) have lower valence scores, faster responses, and greater N1 amplitudes for sad faces. • Individuals with sub-clinical depression have lower valence scores and greater P2 amplitudes for happy faces. • Cognitive and cerebral biomarkers show ne...

Zusammenfassung:	Highlights • Patients with major depressive disorder (MDD) have lower valence scores, faster responses, and greater N1 amplitudes for sad faces. • Individuals with sub-clinical depression have lower valence scores and greater P2 amplitudes for happy faces. • Cognitive and cerebral biomarkers show negativity bias in valence ratings in depression.
