Abstract
Event Segmentation is a process of breaking the continuous events down
to smaller, more understandable parts. The human brain does this passively
and automatically. Events are separated by event boundaries. Previous
research found that there is event boundary related activity within the brain.
Later studies showed that within neural activity we can observe boundaries
between stable neural states. These states align with behaviorally collected
event boundaries. These studies also showed that there is a hierarchical
structure of brain regions that are involved with Event Segmentation.
Furthermore, research suggests that we keep schemas about past events
that we may use to improve our understanding of current events.
All this combined with the predictive nature of the brain led to the
research of this paper. Univariate analyses were conducted to find regions
of the brain that would predict event boundaries during event segmentation.
The results show that multiple brain regions are active. Notable regions
are the Superior and Middle Temporal Gyrus, Precuneus, Posterior
and posterior Middle Cingulum and the Parahippocampal Gyrus. Recent
studies indicate that the aformentioned areas are involved with retrieving
and inferring from past experiences. This suggests that the univariate analyses
conducted may have found regions involved with the prediction of event
boundaries.
