Executive control training does not generalize, even when associated with plastic changes in domain-general prefrontal areas

Simonet, Marie ; Crettaz von Roten, Fabienne ; Spierer, Lucas ; Barral, Jérôme

How executive function training paradigms can be effectively designed to promote a transfer of the effects of interventions to untrained tasks remains unclear. Here, we tested the hypothesis that training with a complex task involving motor, perceptual and task-set control components would result in more transfer than training with a simple motor control task, because the Complex training...

Early attentional processes distinguish selective from global motor inhibitory control: An electrical neuroimaging study

Sallard, Etienne ; Barral, Jérôme ; Chavan, Camille F. ; Spierer, Lucas

In: NeuroImage, 2014, vol. 87, p. 183–189

The rapid stopping of specific parts of movements is frequently required in daily life. Yet, whether selective inhibitory control of movements is mediated by a specific neural pathway or by the combination between a global stopping of all ongoing motor activity followed by the re-initiation of task-relevant movements remains unclear. To address this question, we applied time-wise statistical...

Age-related changes in the bimanual advantage and in brain oscillatory activity during tapping movements suggest a decline in processing sensory reafference

Sallard, Etienne ; Spierer, Lucas ; Ludwig, Catherine ; Deiber, Marie Pierre ; Barral, Jérôme

In: Experimental Brain Research, 2014, vol. 232, no. 2, p. 469–479

Deficits in the processing of sensory reafferences have been suggested as accounting for age-related decline in motor coordination. Whether sensory reafferences are accurately processed can be assessed based on the bimanual advantage in tapping: because of tapping with an additional hand increases kinesthetic reafferences, bimanual tapping is characterized by a reduced inter-tap interval...
