Research Interests:

The work of the lab is directed towards increasing understanding of the nature of cognitive and affective abnormalities in schizophrenia using a variety of methods including behavioral, ERPs, eye tracking, and fMRI. Our current work is focused in several areas.

Attention and Working Memory:  This work is done in collaboration with Steve Luck at UC Davis and Andrew Hollingworth at U. Iowa.  Current experiments are directed at understanding the role of executive control processes in the operation of attentional selection and the interaction of working memory and attention.  In past experiments we have found that patients are surprisingly able to use a variety of cues to guide selection for working memory storage.  We are now trying to determine whether top-down attentional control fails when faced by competition from strong bottom-up signals.  In related work, Britta Hahn is exploring the impact of nicotine on aspects of attention.  
We are also interested in the origins of working memory impairment. In recent work we have found that patients have limitations in WM storage capacity without any evidence of accelerated decay or imprecision of working memory representations.

Reinforcement Learning and Motivation:  This work is done in collaboration with Michael Frank at Brown University and John Sweeney and Ellen Herbener at University of Illinois at Chicago.  The goal of this work is to understand the role of reinforcement learning deficits, likely implicating abnormalities of dopamine signaling, in the motivational and decision-making impairments that are characteristic of many patients with the illness. Through the use of computational modeling we hope to develop a highly specific, mechanistic understanding of these impairments.
In recent work we have found that patients appear to have difficulty representing the value of different stimuli and actions, resulting in slowed initial learning, difficulty matching action selection to experienced value, and alterations in decision-making.  Current experiments are designed to determine the degree to which patients learn from positive as opposed to negative feedback, the extent to which these deficits specifically map onto negative symptoms, and whether these processes are altered by the introduction of antipsychotic treatment. Through the use of fMRI, Jim Waltz is examining the neural systems that are implicated in reinforcement learning deficits.  In related work, Greg Strauss is exploring the role of emotional processing deficits in the origins of negative symptoms.

Development of cognitive measurement approaches:  This is a long-standing focus of the lab that has included the development of the letter-number sequencing test that has been incorporated into the Wechsler Scales, the validation of the RBANS as a brief screening test for general level of impairment in schizophrenia, collaboration on the development of the MATRICS battery, and current collaboration with Deanna Barch, Cam Carter, Steve Silverstein, Angus MacDonald, Dan Ragland, Charon Ranganeth, and Steve Dakin on the NIMH supported CNTRACS initiative that is designed to validate measures based in the cognitive neuroscience literature for use in clinical trials.  Work with Dwight Dickinson has included meta-analysis of the clinical neuropsychology literature and the use of structural equation modeling to examine the role of general and specific cognitive deficits in the illness.

Clinical Trials:  In collaboration with Bob Buchanan and others, we have explored the utility of glutamatergic and cholinergic manipulations as add-on treatments targeting cognitive endpoints. There are multiple on-going trials exploring novel mechanisms.  

Genetics:  Our lab is involved with the NIMH supported B-SNIP consortium that includes Guni Thaker, Carol Tamminga, John Sweeney, Godfrey Pearlson, and Matcheri Keshavan.  The goal of the project is to examine intermediate phenotypes in schizophrenia and bi-polar disorder.
