Emotional Modulation of the Attentional Blink by Pleasant and Unpleasant Pictures

Abstract

ABSTRACT When shown a rapid series of images, attention to a second target that follows in short proximity to a first is diminished—a phenomenon sometimes called an “attentional blink.” Three experiments compared detection of motivationally relevant pleasant, unpleasant, and neutral pictures when they appeared as the second target following a neutral (Experiment 1), unpleasant (Experiment 2) and pleasant (Experiment 3) picture target. The second target followed at lags of 2, 3 or 8 pictures. In all three experiments, detection of neutral pictures was reduced at lags 2 and 3, indicative of an attentional blink. In contrast, unpleasant pictures were detected more than neutral pictures at lags 2 and 3. Unexpectedly, pleasant pictures not only resisted the attentional blink, but they were detected substantially more than other pictures at all lags in all three experiments. Overall, the experiments support the idea that motivationally relevant stimuli preferentially capture attention more than motivationally neutral stimuli.
