Abstract
Segmenting information from the world around us enables us to remember
certain events. Previous literature has shown that the way someone
segments information gives insight into their ability to remember certain
events. Not everybody’s ability to remember events is equally good. This
can be a real struggle because memory is a very important aspect of our
daily lives. It is therefore beneficial to know more about how it works in humans
and discover why some people are better at remembering than others.
This study researched the correlation between someone’s ability to remember
events and the neural states boundaries during event boundaries when
looking at a short movie. With neural states we mean relatively stable brain
patterns. A data-driven method is used to compute the neural state boundaries
from fMRI data that was collected while subjects watched the movie.
The hypothesis was that people with a higher memory score have more and
stronger neural state boundaries around event boundaries. Two analyses
were done, one on group level and one on subject level. In both analyses no
significant difference was found in the neural states around event boundaries
between participants with a high memory score and those with a low score.
So, we did not find a relation between someone’s memory score and the
strength and number of neural states around event boundaries. However, it
is still interesting to research this topic further in future research.
