Event-related potentials during auditory discrimination: attentional and intentional effects
… electrode sites and averaged for evoked potentials. Amplitudes and latencies were measured for four event-related potentials (N1, P2, N2, and P3) at three midline electrode sites (Fz, Cz, pz) and eight bilateral sites (Fp1, Fp2, F3, F4, C3, C4, P3, P4). Measures from the midline and …

An exploration of pre-attentive visual discrimination using event-related potentials
… as a ‘pre-attentive’ component of an Event-Related Potential (ERP) that is related to discriminatory processes. Although well established in the auditory domain, characteristics of the MMN are less well characterised in the visual domain. The five main studies presented in this thesis …

Auditory event-related potentials and cognitive outcome after very preterm birth
… tools are needed, but still lacking. Auditory event-related potentials (AERPs) are neurophysiological measures of cortical sound detection, encoding, discrimination, and attentional processes. Abnormal AERPs have been associated with cognitive and behavioral problems. To date, there has been …

Event-Related Potentials Correlated with State/Trait Anxiety Using Auditory Stimuli
… discover a biomarker for anxiety with the use of event-related potentials (ERPs) and auditory stimuli. Prior research has focused on anxiety, visual stimuli, experimental tasks, and how ERP components relate to them. Few of the studies used auditory stimuli. This study proposes that the P2, P3, …

Joint time-frequency analysis and filtering of single trial event-related potentials.
… is known as the electroencephalograph (EEG). Event related potentials (ERPs) are voltage deviations in the EEG elicited in association with stimuli. Their elicitation require cognitive processes such as response to a recognised stimulus. ERPs therefore provide clinical information by allowing …

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 …

Tactile tribology- investigation of tactile graphics and perception characterization using event-related potentials
… stimulus was carried out by recording the event-related potentials (ERP) using an electroencephalography (EEG) device. The use of squared difference comparison proved to be an effective method to identify the presence of amplitude-based events in reaction to the textured stimulus. Increased …

Event Related Potentials: A Study of the Processing of Gapping Structures in Adolescents
… tools have been developed, including the use of event-related potentials (ERPs) in order to assess how language is processed and developed, and to help better identify the nature of these processes. The purpose of this study was to compare event-related potential effects of speech processing of …

Hemispheric differences in orthographic and semantic processing as revealed by event-related potentials
… LH) apprehend visual words were examined using event-related potentials (ERPs) in a repetition paradigm with visual half-field (VF) presentation. In both hemispheres (RH/LVF, LH/RVF), initial presentation of items elicited similar and typical effects of orthographic neighborhood size, with …

Investigating social cognition and personal space through tactile event-related potentials in virtual reality
… experiment revealed early differences in the P45 event-related potential (ERP) component, with an increased amplitude in the presentation of stimuli in the near space compared to the far space. Later components, specifically the N140 and longer-latency effects, observed in the Nd1 component, …

Thought and action: Event-related potentials and behaviour in a primed and speeded lexical decision task.
… between cognitive and response processes, event-related potentials (ERPs) were recorded from 10 subjects during semantically primed lexical decisions in an Accuracy condition (response deadline 700 msec) and a Speed condition (deadline 450 msec). Targets were the prime's antonym, an …

Event Related Potentials of Syntactic Language Processing in Two Children with Specific Language Impairment: A Case Study
This study examined the electrophysiological activity of two children with Specific Language Impairment (SLI) and two aged-matched peers while listening to syntactically correct sentences versus syntactically incorrect sentences. The study specifically analyzed the N400 and P600 components. The …
