How do action words acquire associations with corresponding motor programs? In motor learning, the postmovement increase in β-oscillations is implicated in the strengthening of the just learned motor program (Moisello et al., 2015). Could the post-movement β-increase similarly promote an association between a movement and a novel word that denotes this movement? 1. During Self-Paced movements, a classic pattern of the perimovement β-decrease and post-movement β-synchronization 2. During ESL, the β-power decrease was the strongest and most widespread 3. During ASL, the β-power increase emerged right after the movement onset and comprised sensorimotor, memory-related medial temporal, medial and lateral prefrontal cortices 4. During ASL, this β-increase predicted trial-by-trial RTs, 
 with faster (more confident) responses followed by the weaker postmovement β-synchronization (600-1200 ms) and at two stages of a trial-and-error search 
 for associations between four acoustically presented pseudowords and movements by hands and feet: Conclusions: Maximal β-oscillations are pertinent to a distinct stage of learning and may serve to strengthen the newly learned association in a distributed memory network.
