Abstract

Recent evidence supports competitive queuing models of action sequencing in which early responses in a sequence are more active than later responses. Despite the abundant support for competitive queuing models, evidence explaining the early mechanisms of action planning are poorly understood. Changes in frontal-midline theta-ERS in the EEG appear to be an index of the amount of co-activation of conflict in the environment and may also serve as a measure for buffering processes during the co-activation of multiple responses in an action sequence. Here, we propose to measure EEG activity while participants type 3-letter and 7-letter English words and 3-letter and 7-letter random strings. We predict that the amplitude of frontal-midline theta-ERS should vary based on both string/word length and type. The results of this experiment will allow us to differentiate between two action planning models.

Changes in cognitive control after high-demand trials during continuous motor performance: Slower RTs and increases in midline theta

Recent evidence supports competitive queuing models of action sequencing in which early responses in a sequence are more active than later responses.
