MY RESEARCH: An Overview I want to know how people think. I am particularly
interested in “high-level cognition,” such as how people understand whole
stories, and solve complex problems. I particularly want to know how the
brain thinks. All research on the brain and on thinking or perceiving,
without regard to the brain, is interesting and useful. But I find it
particularly satisfying to try to link the brain’s wetware to the mind’s
software. Not just for the sake of connecting the mental realm to the
physical, but because evidence from each domain helps constrain theories in
the other, hopefully providing novel insights into both. Which brings me to
my research…
Solving problems with
insight
What leads to moments of insight? One area of interest for
me is creative cognition, and in particular, those breakthrough moments
in problem solving that are often accompanied by an Aha! experience. A
series of behavioral and neuroimaging experiments has begun to
de-mystify how the brain – and mind – achieves insight in
problem-solving. More…. |
Drawing inferences from
stories
How do people “fill in the gaps” when understanding
stories and complex discourse? People seem to draw inferences
effortlessly. But clearly, some cognitive – and neural – effort is
required. I have studied this process with behavioral, neurological, and
most recently, neuroimaging methods.

Putting it all together
How do people understand complex language? I am interested in how the
brain combines the meanings of words so that we can understand the "big
picture" of stories and conversations. Some research uses two or three
word inputs, or sentences, or whole stories to try to get the big
picture here. Again, multiple methods are employed.

Two brains are better
than one
One approach I've taken in most of my research is to
examine differences in the way the right and left hemispheres of the
brain process information. In particular, I’m interested in how the
RIGHT hemisphere (that’s right, the “minor” hemisphere when it comes to
language) processes language. Why? Because it’s more subtle, less is
known about it, and because it may help reveal why the left hemisphere
is good at what it does. More… |
| Other interests,
projects:
* The structure of conceptual representations (varying among types of
words and concepts).
* How mood affects cognitive flexibility, particularly the neural
bases of mood (e.g., positive mood, anxiety) effects on insight problem
solving, discourse comprehension, and creative cognition
* Right hemisphere involvement in recovery from aphasia
* Discourse and semantic processing in Autism |
