'''Utilization behavior''' (UB) is a type of neurobehavioral disorder that involves patients grabbing objects in view and starting the 'appropriate' behavior associated with it at an 'inappropriate' time.<ref name=" Ishihara">Ishihara, K., Nishino, H., Maki, T., Kawamura, M., & Murayama, S. (20022012). Utilization behavior as a white matter disconnection syndrome. Cortex, 38(3), 379-387.</ref> Utilization behavior patients have difficulty resisting the [[impulse (psychology)|impulse]] to operate or manipulate objects which are in their [[visual field]] and within reach.<ref>Lhermitte, F. (1986) Human autonomy and the frontal lobes. Part II: Patient behavior in complex and social situations: the 'environmental dependency syndrome'. Ann. Neurol. 19, 335–343 </ref> Characteristics of UB include unintentional, unconscious actions triggered by the immediate environment. The unpreventable excessive behavior has been linked to [[lesion]]s in the [[frontal lobe]]. UB has also been referred to as "bilateral magnetic apraxia" and "hypermetamorphosis".<ref name=" Eslinger">Eslinger, P. (2002).
