Experimental analysis reveals attentional selection can blur emotional boundaries in faces, influencing perceptions of targets and distractors.

Participants displayed a bias in identifying emotional expressions, resulting in perceived distinctiveness between target faces and distractors.
When the similarity between target and distractors was high, participants reported the target's emotion as more distinct than when it was low.
Visual search tasks were employed to assess how attention affects processing of similar faces within the same category.
These results suggest attention alters perceptual representation, indicating a significant role in how we perceive similar objects.

Fang et al. (2025) studied this question.
