- Abstract
Background: EEG coherence (a measure of cortico-cortical communication) between the motor planning and verbal processing regions in the brain has been proposed as a measure of conscious motor processing (Zhu et al, 2011). We used the Conscious Motor Processing (CMP) factor of the Movement Specific Reinvestment Scale (Masters et al, 2005) as a state measure to examine differences in coherence as novices practiced golf putting in different learning conditions. Methods: Novices (n=13) performed golf putts in three consecutive conditions. In a baseline condition, exploratory learning was induced by providing an insufficient movement instruction. In an implicit condition, a validated golf putting analogy was provided, and in an explicit condition, 6 putting instructions were provided. EEG (at locations Fz, Pz, T3, and T4) was recorded continuously during each condition. Participants completed a state measure of conscious motor processing (CMP) after each condition. Results: No effects were evident in the baseline condition, but a significant positive correlation was visible between CMP state score and T3-Fz coherence in both the analogy condition (r = .702, p = .007) and the explicit condition (r = 0.637, p = .019). Conclusions: Increased conscious motor processing was expected in the explicit condition but not the analogy condition. Masters and Liao (2003) argued that analogies reduce the cognitive effort required to learn a new movement, so we expected less conscious motor processing to be reflected by lower coherence. It is possible that initially processing analogy instructions is cognitively demanding, as suggested by Lam, Maxwell, and Masters (2009). Regardless, the associations between coherence and CMP scores underline that coherence may be a valid neurophysiological indicator of conscious motor processing.
