Our laboratory is
developing a much more detailed understanding of
the underlying neural basis of many complex disorders of
childhood,
including autism, childhood depression, disorders of impulsivity
such
as ADHD, and antisocial personality disorder. This new
information
about the specific brain mechanisms that underlie these
disorders, in
the context of the rapid progress in understanding what these
brain
circuits are doing and how they are doing it, provides a
platform for us
to develop new behavioral interventions that target certain
aspects of
these disorders. The new behavioral interventions will be based
upon
a detailed understanding of the underlying neural basis of each
disorder.
The
development of neurally-inspired behavioral interventions is
based upon new knowledge of plasticity in the brain and the
premise that the brain is capable of considerably more
plasticity than has traditionally been assumed. If we can
develop targeted behavioral interventions that are designed to
strengthen particular aspects of brain function in specific
disorders, we can then use neuroimaging to verify that such
interventions have indeed affected the relevant underlying brain
systems.
This approach can also be
adopted in educational settings and represents a new strategy in
the development of evidence-based education. Specific components
of the curriculum can be implemented and tested using outcome
measures that include the traditional ones as well as direct
measures of brain function. The ability to show that educational
practices have direct effects upon the brain function of
children will provide powerful new evidence for the development
of innovative educational interventions. We believe that a
particularly novel and promising domain in which this idea
requires exploration is the domain of social and emotional
learning, long neglected in the school system but clearly key to
successful life outcomes.
We
believe that this area of our lab’s work has revolutionary
potential. The ability to target specific brain systems through
behavioral interventions is possible in principle, and it
requires study. At this time,
behavioral interventions are capable of producing more specific
biological effects than any medication. Much work is required to
determine the structure and pace of such training and how
particular training procedures should be customized for
different age children. What is remarkable about this effort is
that today direct measures of brain function can be used in the
development stage to provide immediate feedback on the
effectiveness of the interventions in targeting specific brain
systems. This process would enable rapid
adjustments to be made in the nature of training to maximize its
efficiency in producing the desired outcome. We anticipate
beginning this effort with autism, since we have very good
evidence now for how processing information about faces differs
in individuals with autism compared with typically developing
controls. We have begun to design an intervention that is geared
toward improving face processing while keeping social anxiety to
a minimum. This strategy requires systematic testing and is
poised to be launched with appropriate support. Another domain
we wish to move forward with in the near future is the
implementation of educational interventions in the classroom to
promote emotional intelligence. We have specific ideas for
training
procedures designed to improve cooperation and social
reciprocity, and we know something about the brain systems that
underlie these abilities. We have had contact with various
high-level school system
administrators and with local politicians. We believe this
effort is realistic on a pilot basis.
The Opportunity:
Using the methods of modern brain imaging, we are on the
threshold of developing specific behavioral and educational
interventions that are neurally-inspired, i.e., based upon a
sophisticated understanding of the brain mechanisms that underly
specific subcomponents of behavior. We can then use brain
imaging methods as one outcome variable to demonstrate that the
behavioral intervention does indeed produce specific changes in
the brain systems that are hypothesized. The opportunity to
conduct such studies in the school system is particularly
exciting and has revolutionary potential for providing a
scientific rationale for the introduction of methods to train
specific social and emotional skills in children.
