twitter hampers emotional development?

I haven't yet been able to look at the study by Mary Helen Immordino-Yang due to be published by the National Academy of Sciences, but CNN is reporting that a new cognitive study shows that streams of rapid fire information decrease the ability for humans to form morally appropriate emotional responses.

"For some kinds of thought, especially moral decision-making about other people's social and psychological situations, we need to allow for adequate time and refection," said Immordio-Yang.
She said the study raises questions about the emotional cost, particularly for young people, of heavy reliance on a torrent of news snippets delivered via TV and online feeds such as Twitter.

The study apparantly used volunteers responding to real-life situations that were designed to evoke compassion, admiration, etc.  Apparantly some emotions are slower-forming than others, psychologically speaking.

I'm curious how the situations were constructed, and I'll look forward to being able to read the actual study (I had trouble locating it online, so I'm assuming it's not out yet?).  For instance, it seems as if 140 character bursts could be discontiguous (and therefore not allowing for emotions) such as:

Chris:  Am angry at my boss.  I think I'm going to go in there and punch him in the jaw.

Chris:  Wonder where my pen is?  Good thing lunch is coming soon

Chris:  Decided to give my lunch money to the homeless woman that often comes by outside the office

or could construct a single narrative (which reminds me of the way you Tweet an event), like

Chris:  we're waiting for Obama to take the stage.  The anticipation is really high; a woman next to me keeps yelling and then grinning to her friend

Chris:  Music has started!

Chris:  Here he comes!  He and the whole family!

With rising action, it seems like there's a lot more potential for emotional formation.

Further questions:  what is the burst rate?  I only tweet about once a day...  maybe less.  And if tweet streams are received with multiple people, isn't the discontinutiy more due to the number of people talking rather than the rapid fire rate?
