Abstract:Salient emotional visual cues receive prioritized processing in human visual cortex. To what extent emotional facilitation relies on preattentional stimulus processing preceding semantic analysis remains controversial. Making use of steady-state visual evoke potentials frequency-tagged to meaningful complex emotional scenes and their scrambled versions, presented in a 4-Hz rapid serial visual presentation fashion, the current study tested temporal dynamics of semantic and emotional cue processing. The neural d… Show more
