Do happy faces capture attention? The happiness superiority effect in attentional blink.

This study investigated the influence of positive affect on attentional blink (AB) with schematic faces. Results of Experiment 1 showed that the AB effect was smaller for both upright and inverted positive face icons than other face icons (neutral and angry faces) of corresponding orientations, confirming and extending the results of the earlier study by Mack, Pappas, Silverman, and Gay (2002). Results of Experiment 2 demonstrated that this attenuation of AB was unlikely to be attributable to attentional capture by the happy face. Perceptual saliency is suggested as a likely cause of the effect.
