Current and future Directions


Working Memory

One of our long-term interests is working memory, the system that maintains information in an active state, and that guides conscious thought. For over fifteen years, we have been using neuroimaging methods (Positron Emission Tomography, PET, and functional Magnetic Resonance Imaging, fMRI) to study the neural bases of the components of working memory. Our earlier work identified different subsystems for verbal, spatial, and visual-object information. In current studies, we are exploring a number of issues. One concerns how the brain, in particular the prefrontal cortex, maintains information in the face of distraction. Another issue is how working memory is compromised in major psychiatric disorders like Schizophrenia, and how such impairments are related to known disturbances in the neurotransmitter dopamine.

Cognitive Control

Another major interest is cognitive- control processes, which are higher-level processes, like attention and inhibition, that people need to deal with novel or non-routineized situations. Some questions of particular interest include: are the processes that we use to selectively attend to things in the outside world the same as those we use to attend to in our inside world? Are there different cognitive-control processes for filtering out irrelevant stimuli. inhibiting information in memory, selecting among alternative responses, and inhibiting an already prepared response? Which of the preceding processes are impaired in Schizophrenia, and how do these impairments relate to the symptoms of Schizophrenia?

Semantic Memory

What is it that we "know" when we know something about a word or object? Since at least the writings of John Locke, one answer to this question has been that our knowledge is very tied to our perceptual and motor experience. Recent neuroimaging studies of our knowledge of everyday objects and events provides some striking support for this perceptual hypothesis, as the neural areas activated when we answer questions about objects appear to be the same areas that are active when we perceive the object. But there must be abstract knowledge as well. We are using neuroimaging to study how this perceptual knowledge connects to the more abstract knowledge we have about objects and events.

Research Support

Over the years, our research has been primarily supported by the National Institute of Mental Health (NIMH). We have also received support from other governmental agencies and from private foundations. Currently our work is supported by two grants from NIMH.
