We use eye-tracking technology
-
to measure infants'
-
visual attention
-
to two different types of toys,
-
one that's preferred by girls,
-
and one that's typically preferred by boys.
-
And what we showed was that
-
in these very young infants
-
there were sex differences
-
in their toy preferences. And we just
-
think of them as so trivial. "Toys - so what?"
-
But actually this is sort of interesting
-
in the context of toys and why are they important
-
because the types of toys that
-
boys and girls prefer
-
are thought to influence the
-
development of later sex differences.
