[Production of rhythms in XXXX : the central role of attention].

BACKGROUND: @entity161 is a @entity146 that is characterised by a deficit in the fluent sequencing of thought and action. This problem of discoordination might be due to unreliable timing processes associated with a difficulty in allocating sufficient attention. In the present study, we placed ourselves within the hypothesis that @entity161 @entity1 may have difficulties in producing rhythmic tapping actions and that this deficit may be correlated with the degree of @entity854 . METHOD: Subjects were required to tap in rhythm with alternating force levels and/or alternating time intervals (<1s) during trials lasting 24s. In addition, all @entity1 performed an attention task (D2 test). A qualitative analysis of the tap trials was conducted in order to characterise the nature of the deficits that @entity1 revealed. RESULTS: Results showed that all @entity1 revealed significant difficulties in performing the tapping trials. The number of trials removed was correlated with the level of attention dysfunction. Finally, our qualitative analysis revealed that 60% of @entity1 presented attentional lapses - which were never observed in the healthy controls. CONCLUSION: This study revealed @entity51 that resemble, at least on a behaviour level, the clinical lapses observed in @entity161 . These lapses seem to be correlated to the degree of @entity71 . Future studies are now required in order to gain better understanding of the nature of the @entity71 in @entity161 . More specifically, a better definition of the possible functional relationship between clinical lapses, cognitive lapses and action freezing is needed to develop innovating tools for rehabilitation.
