Patients with this syndrome reach out and use common objects introduce by the examiner, who stimulate their palm and fingers without any instruction. UB was associated with frontal lobe lesions, and considered like the first sign of an “environmental dependency syndrome” (Ann Neurol 1986 ; 19 : 335-43). However, Lhermitte’s procedure was criticized by Shallice et al. (Brain 1989 ; 112 : 1587-98), who argued that the ambiguity of the demand of the situation might have “induced” the utilization of objects. So, these authors suggested another procedure and a fractionation of UB, which has been termed “induced” or “incidental”, based on the context of elicitation of object use (Lhermitte or Shallice’s procedures). During the incidental procedure, the patient was engaged in neuropsychological tests in the presence of objects (Brain 1989 ; 112 : 1587-98). While the two definitions of UB are now commonly used, there is no direct comparison of the procedures in the same group of patients with frontal lobe lesions. We investigated UB in a group of 20 patients with frontal lesions, using the induced and incidental procedures. To address the cognitive explanation of UB in terms of a loss of frontal executive control, we also investigated the potential links between this behavior and neuropsychological assessment. Our results showed that there was an independence between induce and incidental UB. There was no correlation between UB and performance on cognitive tasks, showing a possible dissociation between UB and executive control.
