Introduction
Emotional visual scenes are powerful attracters of attention. Evidence suggests that emotional stimuli themselves attract attention, and they can disrupt perception of subsequent stimuli (Anderson and Phelps, 2001). In a visual attention search task, faster reaction time has been found when target is an emotional stimulus than neutral stimuli (Ohman, Lundqvist, & Esteves, 2001). From these result it seems that emotional stimuli enhance perception of such target. However, what is the impact of emotional stimuli on other surrounding non-emotional stimuli. Recent studies suggest that emotional stimuli can impair perception of nearest non-emotional stimuli in rapid serial visual presentation task (Most et al., 2005). Studies using rapid serial visual presentation show that emotional stimuli affect the perception of surrounding non-emotional stimuli. This interaction between emotion and perception can be seen in everyday life. For example, a sudden car accident can impair perception of bus no. for which, you are looking from long time. This impairment caused by emotional stimuli on the perception of non-emotional stimuli called emotion-induced blindness. It seems very similar to attentional blink, as both work only in RSVP task and both show perceptual impairment for the second stimuli. Regardless of surface level similarities, mechanism following attentional blink is different from emotion-induced blindness. Attentional blink is caused by capacity limitation & impaired visual working memory(Chun & Potter, 1995) . Whereas emotion-induced blindness is results of impair perceptual processing (Briana L. Kennedy & Most, 2012).
Emotion-induced blindness
Studies have shown that when task irrelevant emotional scenes preceded the target by two or eight items, emotional scenes impaired perception of target. In typical emotion-induced blindness task, participants view images that appear with in rapid serial visual
