Response-Related Potentials during Semantic Priming: The Effect of a Speeded Button Response Task on ERPs KU Leuven Universiteit Gent
This study examines the influence of a button response task on the event-related potential (ERP) in a semantic priming experiment. Of particular interest is the N400 component. In many semantic priming studies, subjects are asked to respond to a stimulus as fast and accurately as possible by pressing a button. Response time (RT) is recorded in parallel with an electroencephalogram (EEG) for ERP analysis. In this case, the response occurs in the ...
Integration of reward with cost anticipation during performance monitoring revealed by ERPs and EEG spectral perturbations Vrije Universiteit Brussel Universiteit Gent
Effort expenditure has an aversive connotation and it can lower hedonic feelings. In this study, we explored the electrophysiological correlates of the complex interplay of reward processing with cost anticipation. To this aim, healthy adult participants performed a gambling task where the outcome (monetary reward vs. no-reward) and its expectancy were manipulated on a trial by trial basis while 64-channel EEG was recorded. Crucially, on some ...
Empirical evidence on the (perceived) value of information for performance measurement purpose in an erps environment Universiteit Antwerpen
This chapter investigates if and how the introduction of an Enterprise Resource Planning System (ERPS) influences the information characteristics quality, timeliness and complexity. Subsequently we analyze whether the influence of an ERPS adoption on these information characteristics has an impact on the perceived value of information available for performance measurement (PM) purposes. On the basis of the extant literature a structural model is ...
Goal impact influences the evaluative component of performance monitoring: Evidence from ERPs KU Leuven Universiteit Gent
Successful performance monitoring (PM) requires continuous assessment of context and action outcomes. Electrophysiological studies have reliably identified event-related potential (ERP) markers for evaluative feedback processing during PM: the Feedback-Related Negativity (FRN) and P3 components. The functional significance of FRN remains debated in the literature, with recent research suggesting that feedback's goal relevance can account for FRN ...
Effects of Emotional State on Processing Conceptual Mismatches: ERPs in a Picture-Sentence Matching Task KU Leuven
Event-related potential (ERP) studies demonstrated that emotional state immediately affects the processing of different linguistic mismatches (e.g., semantic and syntactic mismatches) in sentences. Furthermore, mood has been shown to impact discourse processing. In these studies, a strong expectancy was evoked by a linguistic context. In the present study, a strong expectancy was induced by a visual (non-linguistic) context paired with a ...
Effect of Affective Personality Information on Face Processing: Evidence from ERPs KU Leuven
This study explored the extent to which there are the neural correlates of the affective personality influence on face processing using event-related potentials (ERPs). In the learning phase, participants viewed a target individual's face (expression neutral or faint smile) paired with either negative, neutral or positive sentences describing previous typical behavior of the target. In the following EEG testing phase, participants completed ...
Language control in bimodal bilinguals: Evidence from ERPs Vrije Universiteit Brussel
It is currently unclear to what degree language control, which minimizes non-target language interference and increases the probability of selecting target-language words, is similar for sign-speech (bimodal) bilinguals and spoken language (unimodal) bilinguals. To further investigate the nature of language control processes in bimodal bilinguals, we conducted the first event-related potential (ERP) language switching study with hearing American ...
Mental workload of young and older adults gauged with ERPs and spectral power during N-Back task performance KU Leuven
Mental workload has been shown to correlate with alpha and theta band power but only few EEG studies focused on the relation between these bands and Event Related Potentials (ERPs), more specifically the P300 component. We report on an EEG study on mental workload where not only young but also older adults performed an N-Back task. Participants watched a sequence of visual pictures and indicated whether the current picture was the same as the ...
Effects of multimodal load on spatial monitoring as revealed by ERPs Universiteit Gent
While the role of selective attention in filtering out irrelevant information has been extensively studied, its characteristics and neural underpinnings when multiple environmental stimuli have to be processed in parallel are much less known. Building upon a dual-task paradigm that induced spatial awareness deficits for contralesional hemispace in right hemisphere-damaged patients, we investigated the electrophysiological correlates of ...
