The Error-Related Negativity: Evidence for a Neural Mechanism for Error-Related Processing
The analysis of response-locked event-related potential (ERP) waveforms from several experiments points to the existence of a neural system involved in processing information associated with errors in choice reaction time tasks. The experiments included a sentence verification task, a Sternberg …

Psychophysiological responses to affective stimuli in high, moderate, and low socialized students
… responses (e.g. startle blink magnitude and ERPs) have demonstrated sensitivity to individual differences in humans (e.g. Patrick, Bradley, & Lang, 1993), as well as discriminating between the valence and arousal qualities of affective stimuli such as photographs depicting varying emotional …

Auditory and Visual Correlates of the Processing of Gapping Structures in Adults
The purpose of this study was to compare event-related potential (ERP) effects of speech processing and effects in sentence reading elicited by sentences containing gapping structures, or a "missing" verb. N400 and P600 waveforms were collected in 20 adults between 18 and 30 years of age. Two …

Depressive Feedback Utilization: The Feedback-Related Negativity as an Index of the`Catastrophic Response to Perceived Failure'
… examined the impact of negative feedback on event-related potentials associated with error detection and correction in individuals with varying levels of depression. Depression is known to be associated with a number of cognitive effects, including deficits in executive functioning. Beats, …

How Do Anxiety, Stress, Impulsiveness, And Sleep Quality Affect Memory
… (EEG) and the Difference due to memory (DM) event-related potential (ERP) effect, to understand how stress, sleep, anxiety, and impulsiveness influence cognitive processing and recall. 51 college students recruited through Eastern Kentucky University’s SONA system completed surveys assessing …

Filters, Neighbors, and Triangles: A Behaviorally and Electrophysiologically Informed Perspective on Visual Word Recognition
Two Event-Related Potential (ERP) studies and one behavioral study are presented in service of a single goal: to evaluate current prevalent computational models of visual word recognition. Specifically, the functionally homogenous cooperative division of labor model (Triangle) and the full family …

An EEG Study on Loneliness and Recognition Memory
… specifically recollection, with smaller ERP parietal old-new effects than less lonely individuals. Forty participants, grouped into less (<em>n</em> = 13) and more (<em>n</em> = 9) lonely groups based on their R-UCLA responses, completed an associative memory task. EEG was used to assess …

Generation of mismatch negativity in a sample of treatment-resistant schizophrenia patients
… by subtracting the standard from the deviant event-related potential (ERP) brain wave. Subjects responded to infrequent visual stimulation while ignoring binaurally presented auditory input. The patient population showed a larger frequency-MMN amplitude than the normal controls. Separate …

Auditory frequency and location processing in an attention-switching paradigm: Evidence of distinct early selection mechanisms
… as well as the relationship of components of the Event-Related Potential (ERP) to these filtering processes. Specifically, Nataanen's ""attentional trace theory"" postulates that a common sensory memory based mechanism indexed by the Negative difference (Nd) wave is responsible for the …

Neural systems supporting enhanced peripheral visual attention in deaf adults
… cortex of deaf individuals. Chapter 3 describes event-related potential (ERP) data on changes in an auditory ERP and attention-related components. Finally, Chapter 4 reviews the findings described above and proposes future directions for this research.

Can I Eat This? Event-Related Potentials are Modulated by Feedback Regarding Edibility
Feedback-related negativity (FRN) is an event-related potential (ERP) component that has been shown to be sensitive to feedback during risk-taking, such that the FRN is larger for negative outcomes. Another ERP wave, the P300, is known to play a role in attentional resource allocation and is …

Three types of sensory gating: exploring interrelationships, individual differences, and implications
… as how different types of sensory gating are related to basic brain processes and to each other, is poorly understood. Using an event-related potential (ERP) paradigm, I measured P50, N100, and P200 filtering, habituation, and orienting and administered a sequence of neuropsychological …

Adaptation and Control State Detection Techniques for Brain-Computer Interfaces
… combining P300 and steady-state visually evoked potentials (SSVEP) paradigms is also proposed. Information transfer is accomplished using P300 event related potential (ERP) paradigm and control state detection is achieved using SSVEP. The system is shown to achieve fast and accurate control state …

ApoE4 Genotype as a Moderator of Brain Responses to Target Stimuli Prior and Subsequent to Smoking Abstinence
… Being able to understand this modulation is potentially quite important given that recent research implies that, relative to non-ε4 carriers, young adult carriers of the ε4 allele exhibit greater cognitive benefits from the use of nicotine. In the present study, electroencephalography (EEG) …

Evaluating Changes in Error-Monitoring Electrocortcial Responses as an Outcome of Attention Bias Modification Training
… the outcome of ABM training using error-related negativity (ERN) an event-related potential (ERP) that is associated with an error-monitoring response after an individual commits an error. To elicit an erroneous response a modified flanker task paradigm was used. The ERN has the potential …

Age-related shifts in hemispheric dominance for syntactic processing
Genetic factors related to handedness, such as history of familial sinistrality, have been linked to neuroanatomical and neurophysiological differences in a variety of brain areas, including those associated with language. However, the functional implications of these differences remain unclear. …

Electrophysiological studies of identifying and modulating the preparatory strategic processes involved in episodic memory retrieval
… research in this domain has largely focused on event-related potential (ERP) effects of sustained amplitude that occur after the onset of retrieval cues, thereby failing to indicate whether such effects might be engaged in a preparatory manner before cue onset. Here, we describe two experiments …

Event-related potential correlates of item and source memory strength
Event-related potential (ERP) studies of recognition memory have shown dissociations between item recognition and source memory, wherein item recognition is associated with the mid-frontal FN400 component, which varies continuously with item memory strength, while source memory is associated with …

The Influence of Neural Reward Processing on Memory in Depression
… which impairs the encoding of reward-related memories, but few studies have directly probed this connection. Such research may benefit from examining the reward positivity (RewP), an event-related potential (ERP) previously linked to reduced reward sensitivity in depression. …
