The current study examined the emotional effects on visual crowding in which the identification of a target stimulus is difficult when the target is presented with adjacent stimuli in subjects’ peripheral vision. In stead of previous research stimulus such as the English letter or a face as stimulus on visual crowding, the Korean letters were employed because only one Korean letter could have meaning and emotion. In experiment 1, we conducted the target identification task in which participants were asked to report the target that contained emotional values (positive, negative) or did not (neutral) were presented alone (isolated condition), or presented with adjacent meaningless Korean letter distractors (crowded condition). The results indicated that whereas positive and negative targets were identified more correctly in the isolated condition (negative > positive > neutral), this benefit disappeared in the crowded condition. Nevertheless, when the target with the meaningless Korean letter distractors was presented, the emotional value of the target could be damaged because stimuli have forms such as one three-letter word. Therefore, in experiment 2, we employed English letters instead of meaningless Korean letters as distractors. The results indicated that negative targets were identified more correctly in not only the isolated condition but also the crowded condition. The results implied that the emotional value of the target is processed despite the existence of adjacent distractors.
