Friday this week (January 29), at 16:00, in room 3074, Arts Building
(TCD), Dr. Brian Murphy (Queen's University Belfast) speaks on
Title: Probing neurocognition with stories
Cognitive neuroscience and psychology are getting more interested in
looking at "naturalistic" behaviour in experiments. Instead of
constructing a carefully controlled experimental task (e.g.
comprehension of grammatically-manipulated sentences), the field is
starting to use games, films, and now stories.
In this talk I'll talk about one joint study in detail, where we use a
chapter from a piece of popular fiction (a Harry Potter novel) to probe
the different subprocesses of story understanding with fMRI
neuroimaging. Modelling different aspects of language understanding in
parallel provides some interesting machine-learning challenges, and the
result is decomposition of brain activity into different locations that
participate in different levels of language processing/representation. I
will also talk about some continuing work to look at how stories engage
a reader/listener's emotions and memory capacity, and whether those
could be used to probe cognitive dysfunction.
