- The effects of electrode impedance on data quality and statistical significance in ERP recordingsEmily S Kappenman
Center for Mind and Brain and Department of Psychology, University of California, Davis, Davis, California 95618, USA
Psychophysiology 47:888-904. 2010..Thus, high electrode impedance may increase noise and decrease statistical power under some conditions, but these effects can be reduced by using a cool and dry recording environment and appropriate signal processing methods...
- Manipulation of orthogonal neural systems together in electrophysiological recordings: the MONSTER approach to simultaneous assessment of multiple neurocognitive dimensionsEmily S Kappenman
Center for Mind and Brain and Department of Psychology, University of California, Davis, CA 95618, USA
Schizophr Bull 38:92-102. 2012..Although the MONSTER approach is primarily described in the context of ERP experiments, it could also be adapted easily for use with functional magnetic resonance imaging...
- Response activation impairments in schizophrenia: evidence from the lateralized readiness potentialEmily S Kappenman
Center for Mind and Brain and Department of Psychology, University of California, Davis, California, USA
Psychophysiology 49:73-84. 2012..These results are incompatible with a failure of patients to suppress competition and are instead consistent with a deficit in activating the correct response...
- Toward the neural mechanisms of reduced working memory capacity in schizophreniaCarly J Leonard
Department of Psychology, Center for Mind and Brain, University of California, Davis, CA 95618, USA
Cereb Cortex 23:1582-92. 2013..We propose that WM impairment in PSZ instead reflects a specific impairment in the ability to distribute attention broadly...
- Impaired response selection in schizophrenia: evidence from the P3 wave and the lateralized readiness potentialSteven J Luck
University of California, Davis, California, USA
Psychophysiology 46:776-86. 2009..These results indicate that, at least in simple tasks, the delayed RTs observed in schizophrenia are primarily a consequence of impairments in the response selection and preparation processes that follow perception and categorization...
