Decoding belief: neural mechanisms of conspiracy message evaluation
… study used electroencephalography (EEG) and event-related potentials (ERPs) to examine neural responses during a conspiracy message evaluation task under varying social credibility conditions (high, ambiguous, individual). Participants evaluated conspiracy and true messages while EEG was …

Is Allocation of Attention Impaired in Fallers Compared to Non-Fallers? An Event-Related Potential Study
… We examined allocation of attention using event-related potentials (ERPs) as participants responded to visual targets while ignoring task-irrelevant auditory distractors. A posterior to anterior shift in electrical brain activity was exaggerated in the faller group compared to the …

Semantic and Phonological Influences on Memory, False Memory, and Reminding
… previously studied items. This experiment uses event-related potentials (ERPs) to examine the brain activity in response to reminding cues for items that were later remembered compared to those that were later forgotten.

Dispositional Mindfulness as a Moderator of Electrocortical and Behavioral Responses to Affective Social Stimuli
… neutral, and fearful facial expressions). Event-related potentials (ERPs) and behavioral responses were examined to discern whether dispositional mindfulness predicted differential neural and behavioral responses indexing attention to, awareness of, and inhibitory control over automatic …

Mild Traumatic Brain Injuries and Their Implications on Changes in Event Related Potentials: A look into Visual Gating (P50)
… (EEG) measures to study the changes in event related potentials (ERPs) associated with sensory gating and how this cognitive property is affected in those who have a self-reported concussion. Here we show that a visual attention and gating mechanism exists in both populations (control …

The time course of attentional bias in anxiety
… in anxiety, the present project collected event-related potentials (ERPs) during the emotion- and color-word Stroop tasks in both anxious and depressed participants. Present data show that emotional information is not always preferentially processed in anxiety and depression and that …

Characterizing the Brain Dynamics and Eye Movement Behavior of Memory-Guided Saccades: a Preliminary Investigation of Distractor Influence on Memory-Guided Saccades
… in saccadic eye movement (SEM) behavior and event-related potentials (ERPs) associated with performance on a memory-guided saccade task with distractor conditions. Thirteen healthy control participants (n = 13; 6 female) were tasked to complete 864 memory-guided saccade trials with both …

Stacked generalization for early diagnosis of Alzheimer's disease
… wavelet analysis was performed on event related potentials (ERPs) of electroencephalogram (EEG) signals. Extracted feature sets were then used to train the ensemble system, based on stacked generalization algorithm, and individual decisions were calculated and compared. The ensemble …

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 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, …

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 …

The Electrophysiology of Written Informal Language
… that underlie informal language. We recorded event-related potentials while participants engaged in a lexical decision task. For this experiment, participants made judgments about Twitter targets primed with semantically related or unrelated words. Classic psycholinguistic studies have shown …

The Sleep, Inhibition, and Performance (SIP) study: An ERP investigation of sleep, stress, and response inhibition in early childhood
… of inhibitory control in children aged 5-8 using event-related potentials (ERPs). Methods: Twenty children were enrolled in this study, which assessed sleep assessment via actigraphy, sleep diaries, and questionnaires. SES and stress were measured through caregiver reports. IC was assessed with a …

Cognitive Control as a Function of Anger Expression Style: A Combined ERP and fMRI Investigation
… with aggression (anger-out), anger is also related to withdrawal motivation (anger-in). Both anger styles are associated with psychopathology but could involve different mechanisms of cognition and emotion processing that could serve to maintain symptoms of depression and anxiety. The …

The influence of semantics on the visual processing of natural scenes
… the processing of visual stimuli? Using Event Related Potentials (ERPs) and good and bad exemplars of natural scenes, we show that top-down expectation, initiated via a category cue (e.g. the word ‘Beach’), dynamically influences the processing of natural scenes. Good and bad exemplars …

Multiresolution wavelet analysis of event-related EEG potentials using ensemble of classifier data fusion techniques for early diagnosis of Alzheimer's disease
… local health clinics for maximum effectiveness. Event related potentials (ERPs) of the electroencephalogram have the potential to become such a diagnostic biomarker for AD.</p> <p>This work investigates the use of ERP signals for the early detection of AD. The analysis of the ERP signals is …

Facial Processing and Social Motivation In Psychopathy: An Event-Related Potential Study
… examined self-report measures, a lab task, and event-related potentials (ERPs) that are related to social, interpersonal functioning and motivation to help elucidate what aspects of psychopathy and ASD are overlapping or unique to support the perspective of psychopathy as an interpersonal …
