Results of Experiment 1.

<p>(A) The average proportion of “right first” responses, separately for each condition as a function of SOA. Positive SOAs indicate that the first stimulus appeared on the right hemifield, whereas negative SOAs refer to first stimuli appearing on the left. The different conditions are: fearful-neutral (FearNeut, solid lines), fearful-fearful (FearFear, dashed lines), neutral-neutral (NeutNeut, dotted lines). The horizontal line corresponds to the 50% response mark (chance level), that is when participants responded “left” or “right” equally often. Significant visual prior entry effects (indicating attentional capture for one of the two stimuli in the pair) would be visualized as horizontal shifts of the point of maximum uncertainty across the 50% response mark. (B) PSS values (in ms), separately for FearNeut (dark grey bar), FearFear (light grey bar), and NeutNeut (white bar) conditions. Positive values indicate prior entry for the left stimulus in the pair, while negative values correspond to prior entry for the right stimulus. None of these values was significantly different from zero, indicating no prior entry for any of the experimental conditions. (C) Mean fear ratings collected at the end of the main experiment, separately for fearful (dark grey bar) and neutral (light grey bar) faces. Fearful faces were consistently rated as more fearful than neutral faces. *** <i>p</i><.001. Vertical bars correspond to standard errors of the mean.
