- Directed and motivated attention during processing of natural scenesVera Ferrari
University of Florida, Gainesville, FL 32610 USA
J Cogn Neurosci 20:1753-61. 2008....
- Detecting novelty and significanceVera Ferrari
University of Florida, USA
J Cogn Neurosci 22:404-11. 2010..The data support an interpretation that the N2 reflects perceptual fluency and is attenuated when a current stimulus matches an active memory representation and that the amplitude of the P3 reflects stimulus meaning and significance...
- Repetitive exposure: brain and reflex measures of emotion and attentionVera Ferrari
Center for the Study of Emotion and Attention, University of Florida, Gainesville, FL 32611, USA
Psychophysiology 48:515-22. 2011..Taken together, the data suggest that the amplitude of the late positive potential during picture viewing reflects both motivational significance and attention allocation...
- A spatiotemporal filtering methodology for single-trial ERP component estimationRuijiang Li
Computational NeuroEngineering Laboratory, Electrical and Computer Engineering Department, University of Florida, Gainesville, FL 32611, USA
IEEE Trans Biomed Eng 56:83-92. 2009..The spatial filter may be interpreted as a noise canceller in the spatial domain. Study with both simulated data and real cognitive ERP data shows the effectiveness of the proposed method...
- Repetitive picture processing: autonomic and cortical correlatesMaurizio Codispoti
Department of Psychology, University of Bologna, Bologna, Italy
Brain Res 1068:213-20. 2006..These findings suggest that while stimulus detection and categorization, reflected in the LPP, is mandatory, autonomic modulation reflects initial orienting responses that habituate rapidly...
- The categorization of natural scenes: brain attention networks revealed by dense sensor ERPsMaurizio Codispoti
Department of Psychology, University of Bologna, Italy
Neuroimage 32:583-91. 2006..These findings suggest that selective attention to category-relevant features reflects the interactions between prefrontal and inferior temporal cortex during visual processing of natural scenes...
- Implicit and explicit categorization of natural scenesMaurizio Codispoti
Department of Psychology, University of Bologna, Viale Berti Pichat, 5 40127 Bologna, Italy
Prog Brain Res 156:53-65. 2006..Although early and late ERP components vary with stimulus relevance, given that they are differentially affected by stimulus and task manipulations, they appear to index different facets of picture processing...
