So what I got (but I don't really know what I am talking about)

When thinking about a story (or a sequence of events) we can parse it in different ways.

We may think about the changes in time/location:

-------

1 he went to the store

2. then went to gas station

3. then went home

4. the next day he woke up.

---------

Or you could think of the emotional changes:

---------

1. he was concerned about being unemployed.

2. then at the gas station he got a call saying he got the job and he starts tomorrow.

3. He is nervous about his first day of work.

------

With fmri we can detect these context shifts.

The thing the paper adds is that by prompting the user to pay attention to 'emotions' or 'location' it affects where these segmentation changes occur in the fmri results.
