Utilization behavior: Patients whose automatic, pragmatic actions are not inhibited, such as grabbing objects and using them. First studied in Lhermitte F. (1983). 'Utilization behavior' and its relation to lesions of the frontal lobes. https://doi.org/10.1093/brain/106.2.237

Comparator Model: This predictive model was first designed for motor control. (Wolpert D.M. and Mial R. C. (1996) Forward Models for Physiological Motor Control) and then applied to the sense of agency: Haggard P. (2005). Conscious intention and motor cognition. https://doi.org/10.1016/j.tics.2005.04.012

Comparator mechanism failure in Schizophrenia: The model serves as an interpretation of schizophrenic symptoms such as delusions of influence, e.g., in Synofzik et al. (2010) Missatributions of agency in schizophrenia are based on imprecise predictions about the sensory consequences of one’s actions. https://doi.org/10.1093/brain/awp291
