| Abstract: | Extensive research has examined Motor Sequence Learning from both a behavioural and neurocognitive perspective using keypress paradigms such as the Discrete Sequence Production task. Recent development of a whole-body Dance Step Discrete Sequence Production (DS-DSP) task enabled the exploration of underlying cognitive processes in more naturalistic movement. As the theta frequency (4 - 8 Hz) is associated with memory encoding and working memory load, the current study examined theta event-related desynchronisation and synchronisation while executing a 6-step sequence according to the DS-DSP paradigm. The study was conducted with 12 participants, who were fitted with a 22-channel mobile EEG system. Results indicate a decrease in RT and relative theta power in the late stages compared to the early stages of learning. Moreover, an increase in theta power relative to the 3rd and 4th step was found in the early learning stages of learning. Usually, a spike in theta power is associated with a temporary spike in step-level RT, however this was not the case in the current study. Furthermore, the pattern of theta power observed in this study is divergent from the theta power observed in previous finger or visual sequence learning studies. This suggests that cognitive processes underlying whole-body sequential learning are different to previously investigated finger-specific or visual sequential learning. |
