On the clinical and cognitive meaning of impaired sensorimotor gating in schizophreniaM E Dawson
Department of Psychology, SGM 501, University of Southern California, Los Angeles, CA 90089 1061, USA
Psychiatry Res 96:187-97. 2000..All in all, the results support the hypothesis that impaired attentional modulation of startle prepulse inhibition reflects basic neurocognitive processes related to thought disorder in schizophrenia...
What does electrodermal activity tell us about prognosis in the schizophrenia spectrum?Michael E Dawson
Department of Psychology, University of Southern California, Los Angeles, CA 90089 1061, USA
Schizophr Res 54:87-93. 2002..Thus, abnormally high electrodermal arousal and reactivity is predictive of poor outcome in at least some patients. The theoretical implications of these findings and directions for further research are briefly discussed...
A longitudinal analysis of eye tracking dysfunction and attention in recent-onset schizophreniaC M Yee
Department of Psychology, University of California, Los Angeles 90095 1563, USA
Psychophysiology 35:443-51. 1998..The possible role of attentional allocation in ETD highlights the need for further examination of the interface between attentional and eye tracking measures of vulnerability to schizophrenia...
Startle reactivity and PTSD symptoms in a community sample of womenA M Medina
Department of Psychology, University of Southern California, Los Angeles 90089 1061, USA
Psychiatry Res 101:157-69. 2001..Results are discussed in light of Type I and Type II stressors, and recent suggestions in the PTSD literature that a subgroup of individuals may experience physiological suppression rather than heightened physiological reactivity...
Under what conditions can human affective conditioning occur without contingency awareness? Test of the evaluative conditioning paradigmMichael E Dawson
Department of Psychology, University of Southern California, Los Angeles, CA 90089, USA
Emotion 7:755-66. 2007..Aware participants showed conditioning with all of the measures; unaware participants failed to show conditioning with all measures. The behavioral, neurophysiological, and therapeutic implications of these findings are discussed...
Development of skin conductance orienting, habituation, and reorienting from ages 3 to 8 years: a longitudinal latent growth curve analysisYu Gao
Department of Psychology, University of Southern California, Los Angeles, CA 90089 1061, USA
Psychophysiology 44:855-63. 2007....
Effects of cigarette smoking on prepulse inhibition, its attentional modulation, and vigilance performanceAnthony J Rissling
Department of Psychology, University of Southern California, Los Angeles, California 90089 1061, USA
Psychophysiology 44:627-34. 2007..Abstinence among smokers produced reliably lower vigilance performance compared to ad lib smoking. The results indicate that smoking abstinence affects the early stages of stimulus processing...
Effects of perceptual load on startle reflex modification at a long lead intervalGary L Thorne
Department of Psychology, University of Southern California, Los Angeles, California 90089-1061, USA
Psychophysiology 43:498-503. 2006..The results are not consistent with the hypothesis that startle inhibition occurs when the lead and startle stimuli are in different modalities under conditions of high perceptual load...
Effects of perceptual processing demands on startle eyeblink modificationAnthony J Rissling
Department of Psychology, University of Southern California, Los Angeles, California 90089 1061, USA
Psychophysiology 42:440-6. 2005..At 1200 ms, targets and nontargets produced nondifferential inhibition during both CPTs, suggesting that modality-specific attention occurred equally for the two tasks...
Attention and prepulse inhibition: the effects of task-relevant, irrelevant, and no-task conditionsGary L Thorne
Department of Psychology, University of Southern California, Seeley G. Mudd Building, Room 501, Los Angeles, CA 90089-1061, USA
Int J Psychophysiol 56:121-8. 2005..Possible reasons for robust attentional modulation at the 60 ms lead interval as well as the usual 120 ms lead interval are discussed...
Sensorimotor gating, orienting and social perception in schizophreniaJonathan K Wynn
Department of Psychiatry and Biobehavioral Science, Geffen School of Medicine at UCLA, United States
Schizophr Res 73:319-25. 2005..By showing a link between sensorimotor gating and social perception, this study supports social cognition's potential role as a mediator of the relationship between neurocognition and social functioning in schizophrenia...
The functional relationship between visual backward masking and prepulse inhibitionJonathan K Wynn
Department of Psychology, University of Southern California, Los Angeles, California 90089, USA
Psychophysiology 41:306-12. 2004..The data are consistent with the hypothesis that recovery from backward masking effects is affected by sensory gating acting in part to gate out the interruptive effects of the mask...
Modification of sudden onset auditory ERP by involuntary attention to visual stimuliSerkan Oray
Department of Psychology, University of Southern California, Los Angeles, CA 90089-1061, USA
Int J Psychophysiol 43:213-24. 2002..The activation of the exogenous attention system by sudden auditory onset can be modified by involuntary visual attention in a cross-model, passive prepulse inhibition paradigm...
Probing attentional dysfunctions in schizophrenia: Startle modification during a continuous performance testErin A Hazlett
Department of Psychiatry, Box 1505, The Mount Sinai School of Medicine, 1 Gustave L Levy Place, New York, NY 10029, USA
Psychophysiology 45:632-42. 2008..Both groups also showed equal inhibition at 120 ms during passively attended prepulses, suggesting that automatic attentional processes were not impaired in these patients...
Electrodermal predictors of functional outcome and negative symptoms in schizophreniaAnne M Schell
Department of Psychology, Occidental College, Los Angeles, California 90041, USA
Psychophysiology 42:483-92. 2005....

Psychophysiology 39:124-32. 2002..Among measures of responding to nontask stimuli, a simple count of the number of orienting responses occurring was more stable than was a traditional trials-to-habituation measure...
