Imitation and utilization behavior have previously been described in terms of a simple interaction between an examiner and a patient, and were interpreted as an excessive dependence on environmental cues. In this study, patient dependence was observed in complex situations of everyday life. Two patients with focal unilateral frontal lobe lesions were observed while in a doctor's office, a lecture room, a car, and a garden, while visiting an apartment where various activities were possible, and… Expand
A contribution to the study of environmental dependency phenomena: The social hypothesis
TLDR
Clinically, the findings help to rehabilitate the definitions of Lhermitte (1983, 1984) and challenge the classical interpretation in terms of an executive control deficit, and a new interpretation of environmental dependency phenomena is provided which could be helpful to orient the neuropsychology of frontal syndrome.

Environmental dependency phenomena in schizophrenia: a pilot study
TLDR
This pilot study demonstrates the presence of environmental dependency in schizophrenia and suggests specific prefrontal dysfunction for each subgroup of patients and demonstrates a dissociation between socio-cognitive and neurocognitive performance in schizophrenia. Expand
Feeling frontal dysfunction
TLDR
The authors found that ratings on the modified Kral procedure correlated well with subjective assessments of facilitory paratonia, with other frontal motor signs, somewhat with frontal cognitive signs, and with overall dementia severity. Expand
Frontal versus dysexecutive syndromes: relevance of an interactionist approach in a case series of patients with prefrontal lobe damage
TLDR
This pilot study reports the case of eight patients with frontal lobe damage who were assigned to one of two groups based on whether or not they showed a dysexecutive syndrome, and contributes to defining more precisely the distinction between “frontal” and “dysexECutive” syndromes. Expand
When the self represents the other: A new cognitive neuroscience view on psychological identification
TLDR
It is suggested that within this shared neural network the inferior parietal cortex and the prefrontal cortex in the right hemisphere play a special role in the essential ability to distinguish the self from others, and in the way the self represents the other. Expand
Discrepancy between social and nonsocial decision-making under uncertainty following prefrontal lobe damage: the impact of an interactionist approach
TLDR
The possibility of identifying components of social and nonsocial decision-making, which could be helpful in understanding the behavioral disorders of FL patients, is raised. Expand
Moral conduct and social behavior.
TLDR
Clinicoanatomic observational studies and experimental evidence from patients with acquired sociopathy/psychopathy indicate that abnormalities of MCSB are the final common pathway of single or mixed impairments of subordinate psychologic and neural domains that support M CSB. Expand
On a Peculiar Environmental Dependency Syndrome in a Case with Frontal-Temporal Damage: Zelig-like Syndrome
TLDR
A patient with frontal-temporal damage from cerebral hypoxia, affected by amnesic disturbances and behaviour disorder, who presented a peculiar phenomenon of environmental dependency, was interpreted as a loss of frontal inhibition whose function was the control of his own identity and consequent “attraction” towards a social role proposed by the environment. Expand
The role of the orbitofrontal cortex in regulation of interpersonal space: evidence from frontal lesion and frontotemporal dementia patients.
TLDR
Light is shed on the role of the orbitofrontal cortex in regulating social behavior and may serve as a simple diagnostic tool for dementia or lesion patients. Expand
The clinical and anatomical heterogeneity of environmental dependency phenomena
TLDR
This study confirms the high frequency of two environmental dependency phenomena- grasping and imitation- in patients with frontal lobe syndrome and the rarity of utilization behavior and correlated scores obtained by assessing grasping, imitation and utilization behaviors with both neuropsychological executive test performance and grey matter density on MRI using Voxel-Based Morphometry (VBM).

'Utilization behaviour' and its relation to lesions of the frontal lobes.
TLDR
The neuropathological observations lead to the suggestion that lesions of the orbital surface of the frontal lobe, and perhaps of the head of the caudate nucleus, are responsible for a new type of behaviour, termed 'utilization behaviour', observed among patients affected with left or right unilateral, or bilateral, frontal lesions.
