- 요약Creative problem-solving is a hallmark of high-level cognitive achievement in humans. To derive novel solutions and solve new problems, people engage a variety of cognitive resources in a temporally organized way. Previous literature has demonstrated the importance of temporal dynamics of brain activities in studying neural substrates of complex cognitive functions. The current thesis project examined temporal dynamics of neural oscillations by extracted hidden brain states from EEG data using a hidden Markov model. In the first two studies, the brain state modeling approach was developed and validated on two datasets recorded when participants solved different verbal puzzles. The trial-by-trial decoding afforded by the model depicted the unfolding and interaction of oscillation processes (brain states) during problem-solving, thereby associating their temporal dynamics with behavioral outcomes. Notably, alpha-band synchronization was robustly associated with insight problem-solving across different tasks. The third study extended the brain state modeling approach to resting-state EEG data. Results suggested that brain states during rest could be reliably identified, cognitively meaningful, and mostly stable within individuals. Brain states extracted from resting sessions overlapped with those extracted from problem-solving sessions. Furthermore, the study provided preliminary evidence that brain states during rest were predictive of individual differences in cognitive performance and problem-solving tendencies. Overall, the findings from these studies offer significant insights into the dynamic oscillatory processes involved in creative problem-solving and task-free rest. They demonstrated the utility of the brain state modeling approach in revealing the temporal dynamics of neural activities. This approach holds the potential for reconciling findings from previous EEG studies and generating new hypotheses to further our understanding of complex cognitive functions.
