Typically these deficits in social cognition are believed to account for a wide variety of delusions and hallucinations. Problems in low-level social processes such as self-other integration may underlie these higher-level deficits. Research focusing on actual interacting individuals is scarce and to our knowledge, only one study investigated self-other integration in schizophrenia during a joint setting in schizophrenic patients. Using a spatial variant of the social Simon task, where the to-be categorized stimuli were triangles pointing towards the left or right, it has been demonstrated that schizophrenic patients do not show a social Simon effect, suggesting that self-other integration is absent (Liepelt et al., 2012). Importantly however, schizophrenia is also characterized by deficits in spatial cognition, making it likely that the nature of the stimuli hindered a proper measurement of the social Simon effect. In two experiments, we further investigated self-other integration in schizophrenia using a non-spatial variant of the social Simon task with colors. During the first experiment, 16 healthy controls and 15 schizophrenia patients performed a social Simon in both a joint and an individual (go/nogo) setting. Patients showed an enlarged Simon effect in the joint setting that could not be attributed to general slowing. In Experiment 2, the social nature of this enlarged effect was further investigated. For this purpose, 29 healthy controls and 35 schizophrenia patients performed a social and a regular Simon task. Here again, a selective enlargement of the Simon effect in the social condition was observed. These outcomes indicate that schizophrenia patients have deficits in low-level processes required for successful joint action, but in contrast to previous research, these observations suggest that self-other integration deficits in these patients are merely the result of hypersensitivity towards the social environment in a way that it affects their own action planning during joint task performance.
