TUESDAY, Sept. 14 (HealthDay News) -- Children may actually see
the world differently than adults, researchers have found.
Unlike adults, children younger than 12 don't combine different
sensory information in order to understand their surroundings, the
study authors say.
In two new studies, U.K. researchers found that not only do
children separate different senses such as vision and sound, their
brain also separates input it receives when looking at a scene with
one eye compared to with both eyes.
One study compared how children and adults combine perspective
and binocular depth information and found that the ability to blend
these two types of depth information is not present until about age
12.
The second study found that children younger than 6 years old
were able to keep perspective and binocular visual information
separate, while adults did not have this ability.
The findings are published in the Sept. 13 edition of the
Proceedings of the National Academy of Sciences.
In a news release from the journal's publisher, study co-author
Denis Mareschal, from the Center for Brain and Cognitive
Development at Birkbeck, University of London, explained: "Babies
have to learn how different senses relate to each other and to the
outside world. While children are still developing, the brain must
determine the relationships between different kinds of sensory
information to know which kinds go together and how. It may be
adaptive for children not to integrate information while they are
still learning such relationships -- those between vision and
sound, or between perspective and binocular visual cues."
