In additional-singleton studies, visual search times are slower when an additional singleton is present as compared to when it is not. This finding tends to reflect that perceptually salient, but task-irrelevant stimuli capture attention. Recently, the additional-singleton paradigm has also been used with emotional faces (Glickman & Lamy, 2018): When participants search for a target face among a set of distractor faces based on a specific feature, and some trials contain an emotion distractor, search times tend to slow down due to the presence of the emotional singleton, indicating that emotional expressions capture spatial attention despite being task-irrelevant. We conceptually replicated this effect. In our experiment participants performed a face search for a uniquely tilted target and then categorized its gender (i.e., they had to perform a “social processing” task), with angry faces as singletons on half the trials. We found significant differences between singleton present and singleton absent conditions. This conceptual replication was done in anticipation of a further experiment testing for the social processing mode hypothesis, where attentional bias towards an emotional stimulus is dependent on the activation of a social mode. Evidence for the social processing mode has been shown with the dot-probe paradigm, where the targets/instructions are manipulated to reflect a social or an asocial mode (Wirth & Wentura, 2018a; 2019; 2020). We discuss these findings in terms of replicability, as well as whether singleton effects appear when social features are task-relevant.
