• Dealing with strong motor automatisms often requires interference control. • Prepotent response inhibition is suggested to be associated with successful control of interference from procedural skills. • Interference was intentionally created within a typing paradigm and was able to disrupt participants in their automatized typing behavior. • Stimulus-locked ERPs suggest an involvement of response inhibition in trials of successful interference control (reflected by larger P3 components). • Results corroborate a crucial role of response inhibition for successful interference control and the idea of inhibition representing a multidimensional construct. Changing pre-existing, automatized motor skills often requires interference control. Prepotent response inhibition – one subdimension of inhibition – has been theorized to be particularly associated with successful interference control in motor skills. Recent evidence suggests that different inhibition subdimensions elicit distinct ERP patterns (with larger P3 components for response inhibition). Therefore, we examined whether a similar ERP pattern would arise in a task demanding participants to overcome interference emerging from strong motor automatisms. This was realized within a typing paradigm involving a letter switch manipulation which is able to produce strong, immediate interference effects. Most importantly, stimulus-locked ERP analyses revealed an enhanced P3 component at frontal, central and most pronouncedly parietal sites for interference trials, in line with previous reported patterns for response inhibition. Together, different analyses provide first insights into the electrophysiological correlates of motor skill change, corroborating the pivotal role of response inhibition for successful interference control.
