Transcript
Please wait while the transcript is being prepared...
0:00
My name is Sarah-Jayne Blakemore,
I'm the head of the Developmental
Cognitive Neuroscience Group at UCL and
I will be talking about the social
brain and its development.
0:11
In my talk I'm firstly going to describe
what I mean by the social brain,
I'll then talk about how the social brain
develops structurally particularly during
the period of adolescence, I'll then
talk about functional development
of the social brain in adolescence,
and finally I'll
talk about behavioural development of
'theory of mind' usage during adolescence.
First of all, what is the social brain?
0:37
The aspect of the social brain that my
research is most focused on is the way we
are very readily able to read other
people's social/emotional responses.
Without having to ask people, you have a
very good idea of what's going on in their
heads, what they're thinking and
feeling at this precise moment in time.
Unintended pause, please skip to 1:41,
