Processing demands during the performance of rhythmic motor sequences

Previous studies on executive task management have shown that selection,
implementation, and updating of mental-sets requires cognitive control.
Processing demands for cognitive control increase when different sets compete
for implementation in to a certain action. Krampe, Mayr & Kliegel (2005)
proposed a cognitive control perspective on rhythmic timing inspired by the
rhythm program hypothesis of Vorberg & Wing (1996). According to this model,
rhythm programs are mental-sets representing the serial order and the relative
duration of motor events (e.g. taps) in a sequence. In this ongoing study we
investigate processing demands during the performance of rhythmic motor
sequences. Participants learn different rhythms and are asked to produce them
in a pure (one rhythm repeatedly) or a mixed (alternating between different
rhythms) condition. In the latter condition we use an AABB paradigm to contrast
effects of implementing a certain rhythm and switching between different
rhythms. We also vary the degree of changes between rhythms and the point
occurrence of the change in the sequence. We expect that competition between
rhythm programs of consecutive sequences will lead to an increase in processing
demands. In future studies we will investigate how cognitive control in rhythmic
timing is affected by concurrent tasks and how rhythmic sequencing and finger
sequencing interact. In addition, it is of great interest how chunking of motor
sequences is affected by rhythm.
