Attentional blink with emotional faces depends on emotional expressions: a relative positive valence advantage

ABSTRACT

Contribution of emotional valence and arousal to attentional processing over time is not fully understood. We employed a rapid serial visual paradigm (RSVP) in three experiments to investigate the role of valence and arousal. In three experiments, participants had to identify the expression of the two targets (experiment 1 - happy and angry; experiment 2 - angry and surprise; experiment 3 - happy and surprise) presented among neutral upright face distracters. In the first and third experiments, the two targets differed both in valence and arousal ratings. In experiment 2, the surprise and angry expressions differed in terms of valence but were matched for arousal. There was a happy expression advantage (lesser attentional blink) when the first target was anger (experiment 1) or surprise (experiment 3) and a surprise expression advantage when the first target was anger (experiment 2). There was a backward blink with reduced detection of the first target primarily by the relatively more positive valence second target. These results indicate that the benefit for happy and surprise expressions in comparison to angry expression identification is probably due to valence (more positive) and not arousal. Our results demonstrate a novel dynamic interplay of emotional information on temporal attention.
