| Abstract: | Extensive research into motor sequence learning (MSL) has gathered insights into how learning can be conceptualised and presented in memory. Frameworks like the Cognitive Framework for Sequential Motor Behaviour 2.0 (Verwey et al., 2015; Verwey, 2023) have conceptualised the different phenomena that occur during MSL, namely the initiation, concatenation, and execution of movements. This research prompted the investigation into various brain oscillations to explore their role in facilitating or inhibiting MSL. Theta oscillations (4-8 Hz) have been identified as a key factor in working memory and the integration of movements into memory. This thesis explored the role of theta activity in a mobile EEG discrete dance sequence task. 13 participants learned a six-step sequence using a go/no-go discrete dance sequence task over six blocks. During movement execution, their performance was tracked alongside brain activity measured by a 22-channel EEG cap. Results showcased a significant decrease in response times over time that peaked around block five. Theta activity increased for the first three blocks and decreased significantly for blocks four and five. During the last block participants encountered an unfamiliar sequence. This caused an increase in both response times (i.e. slower reactions) and relative theta activity. These findings support the idea that learning new motor sequences initially increases the mental load required to process the new stimuli as indicated by increased theta activity. As movements become increasingly integrated into memory this demand seems to decline. |
