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… 

Environmental dependency phenomena in schizophrenia: a pilot study

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.

Feeling frontal dysfunction

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.

Frontal versus dysexecutive syndromes: relevance of an interactionist approach in a case series of patients with prefrontal lobe damage

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.

Discrepancy between social and nonsocial decision-making under uncertainty following prefrontal lobe damage: the impact of an interactionist approach

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.

Moral conduct and social behavior.

On a Peculiar Environmental Dependency Syndrome in a Case with Frontal-Temporal Damage: Zelig-like Syndrome

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.

The role of the orbitofrontal cortex in regulation of interpersonal space: evidence from frontal lesion and frontotemporal dementia patients.

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.

The clinical and anatomical heterogeneity of environmental dependency phenomena

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).

Orbitofrontal Cortex and Social Behavior: Integrating Self-monitoring and Emotion-Cognition Interactions

It is suggested that damage to the orbitofrontal cortex impairs self-insight that may preclude the generation of helpful emotional information and avenues for neurorehabilitation of patients with social deficits subsequent to orbitof prefrontal damage are suggested.



'Utilization behaviour' and its relation to lesions of the frontal lobes.

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.
