Mirroring and Mentalizing in Autism - Detection of Different Types of Movements and Emotions in Autism Spectrum Disorder
Two different neural systems and their associated functions have been identified by social neuroscience as important factors of social interaction: the mirror neuron system (MNS) and the mentalizing system (MENT), mirroring and mentalizing, respectively. Since anomalies in social behavior are core to autism spectrum disorder, observation of impairments in this disease is particularly interesting for research on those functions. Yet, the majority of studies concentrated respectively on one of the two networks or associated abilities or did not take into account clinical populations to learn more about the synergy of both during social encounters. This study is the first to examine those complex skills between two diagnostic groups using an appropriate behavioral approach. A new set of stimuli allowed to compare mirroring and mentalizing by addressing both recognition abilities with the same visual input, controlling for potentially confounding variables.Results indicate anomalies in the detection of mood, but not in the detection of actions in autism, suggesting impairments in mentalizing but normal functioning of mirroring abilities. Since no differences between mirroring and mentalizing in the group of healthy control participants were detected, findings can be interpreted as an indication for a primal separation of both functions or neural networks, respectively. However, a synergy seems to be probable, but needs to be clarified by further research. Additionally, a significantly higher number of unanswered trials was observed in persons with autism, indicating a tendency of avoidance of uncertainty in autism.
