P300-Based BCI Performance Prediction through Examination of Paradigm Manipulations and Principal Components Analysis.
… A brain-computer interface (BCI) using the P300 event-related potential provides communication that does not depend on neuromuscular activity and can be useful for those with LIS. Currently, there is no way of determining the effectiveness of P300-based BCIs without testing a person's …

Adaptation and Control State Detection Techniques for Brain-Computer Interfaces
… for constructing adaptive classifiers for P300 BCIs, which were trained from very little data. The proposed approach is able to build high-performance classifiers from just a few minutes of labeled data by making efficient use of unlabeled data. An asynchronous BCI system combining P300 and …

Child Maltreatment, Behavior Problems, And Neurocognition: Main And Mediation Effects
… mediating effect of neurocognition, measured by P300 event-related potential in the relationship between physical abuse and externalizing behaviors. As a different line of inquiry, Chapter 4 tested the risk effects of neurocognition measured by IQ and behavior problems on the likelihood of …

Investigating cortical arousal and cognition in schizophrenia and methamphetamine-induced psychotic disorder: an electroencephalography and cytokine study
… detection task (CTD); (3) differences in the P300 event-related potential waveform (ERP), a measure of attention, during the CPT and CTD; (4) cognitive performance and relative frequency and ERP (N170, P300) during the STROOP task, a measure of working memory and executive function; (5) the …

Electrophysiological Correlates of Cognitive Processing in Adolescents Reporting Psychotic-Like Experiences
… shown to share many of the same schizophrenia-related risk factors as patients with schizophrenia (the clinical psychosis phenotype; Kelleher & Cannon, 2011). The following thesis employs both behavioural and electrophysiological methods in an attempt to uncover possible correlates of PLEs in a …

Improving Brain-Computer Interface Performance: Giving the P300 Speller Some Color.
<p>Individuals who suffer from severe motor disabilities face the possibility of the loss of speech. A Brain-Computer Interface (BCI) can provide a means for communication through non-muscular control. Current BCI systems use characters that flash from gray to white (GW), making adjacent character …
