• This research project investigated how motor activity, such as cycling, influences the acquisition of foreign language vocabulary under two distinct conditions of auditory-motor-synchronisation. In a mixed subject design, 48 participants had to learn 40 Polish-German vocabulary pairs by auditory presentation over headphones in two different conditions, in which they performed motor activity cycling on a bicycle ergometer: in experiment 1, vocabulary was presented in a fixed rhythm while in experiment 2, participants self-initiated the presentation of vocabulary through pedalling. After having listened to the word pairs, they had to perform online vocabulary tests, one directly after the learning session and a second one 24 hours later from home. Additionally, the individual pitch perception preference (i.e. fundamental vs. spectral pitch perception) of the participants was determined. The results showed that fundamental listeners forgot significantly more vocabulary than spectral listeners during the fixed than during the self-initiated condition. There was no difference within the groups for the self-initiated condition. The analysis of the motor data revealed a significantly more accurate synchronisation for fundamental listeners during the fixed condition. Therefore, this study provides first evidence for the benefit of self-initiated auditory-motor synchronisation in the process of learning a foreign language in adults. It also reveals that pitch preference has an effect on auditory-motor synchronisation.
