Relevant URL: Neuroimaging studies with adults have identified cortical regions
reliably recruited when people think about other people's thoughts
('theory of mind'): bilateral temporo-parietal junction (TPJ),
posterior cingulate, and medial prefrontal cortex. These same regions
were recruited in children aged six to eleven years, when they
listened to sections of a story describing a character's thoughts,
compared to sections of the same story that described the physical
context. In adults, the right TPJ is recruited selectively when
subjects read about a character's thoughts, but not other facts about
a person. Developmental change in response selectivity was observed
in just this one region: the right TPJ was recruited equally for any
information about people in younger children, but only for
descriptions of mental states in older children.
