Extrafoveal capture of attention by emotional scenes: affective valence versus visual saliency

Pairs of emotional (pleasant or unpleasant) and neutral scenes were presented peripherally (5 degrees away from fixation) during a central letter-discrimination task. Selective attentional capture was assessed by means of eye movement orienting, i.e., probability of first fixating a scene and the time until first fixation. Static and dynamic visual saliency values of the scenes were computationally modelled. Results revealed selective orienting to both pleasant and unpleasant relative to neutral scenes. Importantly, such effects remained in the absence of visual saliency differences, even though saliency influenced eye movements. This suggests that selective attention to emotional scenes is genuinely driven by the processing of affective significance in extrafoveal vision.

Adaptive attunement of selective covert attention to evolutionary-relevant emotional visual scenes Fernández-Martín, Andrés (UNIR); Gutiérrez-García, Aida; Capafons, Juan; Calvo, Manuel G (Consciousness and Cognition, 05/2017)We investigated selective attention to emotional scenes in peripheral vision, as a function of adaptive relevance of scene affective content for male and female observers. Pairs of emotional neutral images appeared ...
Calvo, Manuel G; Avero, Pedro; Fernández-Martín, Andrés (UNIR); Recio, Guillermo (Emotion, 12/2016)We investigated the minimum expressive intensity that is required to recognize (above chance) static and dynamic facial expressions of happiness, sadness, anger, disgust, fear, and surprise. To this end, we varied the ...
