There is ample evidence showing that decision times are shorter when detecting two targets for which the same response is required, compared to when only one of the targets is present—resulting in a redundancy gain. Though effects of perceptual manipulations on redundancy gains are established, effects of social associations are still unclear. Here, we examined for the first time whether associating arbitrary stimuli with in-group as opposed to out-group targets modulates redundancy gains. Participants made associations between a shape, a colour and either in- or out-group labels. They then had to
discriminate whether in- or out-group stimuli appeared (single or redundant features). Responses to in-group but not to out-group stimuli violated predictions of models in which the associated features are processed
independently, and were consistent with in-group stimuli being processed with super-capacity. Our results, replicated across two experiments, providing
the first evidence that there is enhanced perceptual integration for information associated with an in-group.
