Abstract
This work consists of two studies performing three different experiments. They make use of the temporal binding effect (TB), the judgment error in a time estimation task when performing voluntary actions. TB manifests as an underestimation of durations between two events and particularly occurs when judging the time between actions and their effects. As TB reliably occurs during self performed action, it can be used as a measurable correlate to the Sense of Agency (SoA). As SoA is often altered during states of mental disorder, TB tasks pose an implicit way to assess disturbances and alterations in its experience. Additionally, TB relies heavily on predictive processes allowing for deductions about potentially underlying cognitive mechanisms. The paradigm employed in the two studies merges existing theory on the influence of social cognitive processes on TB and adapts it to investigate their influence on Autism Spectrum Disorder (ASD) as a showcase for further mental health research. The aim of the paradigm was to disentangle the difference between bottom-up perception and top-down belief on TB. It does so by using a face stimulus and a confederate study design. The results identify a social hyperbinding. TB emerges for changes in faces, as well as for interactions with a human partner. The effect is larger when compared to interactions with non-face stimuli and actions performed without a partner. Social hyperbinding appeared whenever social information was present in the action-event sequence, irrespective of perception and belief. For participants with ASD social hyperbinding was smaller as compared to participants without ASD. These results indicate a differential processing of social information during action-event monitoring and might reflect stronger SoA during social interaction for individuals without ASD. The paradigm is discussed in terms of its limitations and its amendability to the investigation of other mental disorders, particular to Schizophrenia and Major Depressive Disorder (MDD).
