Abstract
Recent and convergent studies in neuropsychology have suggested the importance of frontal regions to the integrity of a number of functions such as metamemory capacities, executive functions, and social skills (Theory of Mind : ToM). In this original work, following Stuss et Anderson (2004), we assume a link between disturbances of these functions. We proposed to 16 frontal patients and 20 matched healthy subjects a protocol designed to test metamemory, ToM and executive functions in order to analyze the relations between disturbances of self-awareness (metamemory) and awareness of others (ToM), and cognitive control (executive functions). Our results confirm the importance of frontal lobes on these capacities. No correlation was found between measures of metamemory, measures of ToM and executive scores. The observation of individual profiles emphasizes the existence of dissociations between self awareness and consciousness of the others, and between these two forms of metacognitive control and the executive functioning. These results confirm the importance to engage more studies combining aspects of ToM, metacognition and executive control, to better understand the organization and architecture of the functions supported by frontal lobe.</p>
