Personality modulation of P300 wave recorded within an emotional oddball protocol

Abstract

SummaryObjectives. -Several studies reported that personality modulates responses to emotional stimuli, including cognitive and attentional aspects of the emotional response. The aim of this study was to refine these results while using visual event-related potentials (ERPs) and referring to Cloninger's personality model. Methods. -ERPs were recorded in 46 normal subjects within a visual oddball protocol with checkerboards as the standard stimuli and pictures selected as neutral, pleasant or unpleasant from the International Affective Picture System as the target stimuli. Results. -N200 amplitude was smaller and P300 amplitude was larger following the presentation of pleasant pictures in low-harm avoidance but not high-harm avoidance subjects. Conclusions. -These results support the idea that both automatic and selective cognitive processing of emotional pictures is modulated by personality. © 2009 Elsevier Masson SAS. All rights reserved.

Le but de la présente étude est d'affiner ces résultats en utilisant des potentiels visuels liés à l'événement et en faisant référence au modèle de personnalité décrit par Cloninger. Méthode. -Les potentiels évoqués ont été enregistrés chez 46 sujets sains lors d'un protocole oddball visuel utilisant des damiers comme stimuli standard et des images neutres, plaisantes et déplaisantes tirées de l'International Affective Picture System comme images-cibles. Résultats. -L'amplitude de la N200 était plus faible et l'amplitude de l'onde P300 plus importante après la présentation d'images plaisantes chez les sujets présentant un score bas à l'évitement du danger mais pas chez les sujets caractérisés par un score élevé à cette dimension. * Corresponding author.

Conclusions. -Ces résultats supportent l'idée que les traitements automatiques et sélectifs des stimulations émotionnelles sont modulés par la personnalité.

The Effect of the Physical Presence of Co-Players on Perceived Ostracism and Event-Related Brain Potentials in the Cyberball Paradigm

“…A corresponding process might be elicited in our group Presence : Here, the reception of the ball in the exclusion condition signaled a re-involvement in the game and thereby reduces social threat. According to previous results, however, we have to take into account that a N2 reduction in the group Presence is expected to be associated with a corresponding modulation of the P3 amplitudes [37]. As stated in the result section, this was not the case in our study.…”

“…Within an emotional oddball design, a reduction of N2 amplitude was triggered by pleasant stimuli, and assumed to reflect a reduction in the defense system sensitivity [37]. A corresponding process might be elicited in our group Presence : Here, the reception of the ball in the exclusion condition signaled a re-involvement in the game and thereby reduces social threat.…”

“…It is important to note, however, that this process is not directly reflected by the N2, but rather by an independent ERP positivity (P2) superimposed. The more direct account – N2 amplitude as an indicator for social threat – appears to be less convincing since the P3 amplitude is not modulated as well [37], [41].…”

Frontal-parietal responses to “oddball” stimuli depicting “fattened” faces are increased in successful dieters: An electroencephalographic study

“…In a typical "oddball" paradigm, subjects are instructed to respond when the rare stimuli appear interspersed among frequent stimuli (Briggs and Martin, 2009;Cano et al, 2009;Cutmore et al, 2009;Mardaga and Hansenne, 2009;Lee et al, 2010;Bocquillon et al, 2011). The rare stimuli usually induce a marked enhancement of posterior P300 amplitude, reflecting late inhibitory processes associated to selective conscious attention and working memory for the update of the stimulus context (Nandrino et al, 1996;Polich, 1993Polich, , 2007.…”

Harm avoidance in adolescents modulates late positive potentials during affective picture processing

“…Other research suggests that low‐HA individuals exhibit attentional bias toward positive stimuli (Taylor et al, 2011). For example, low‐HA adults elicit smaller N2 and larger P3 amplitudes after the presentation of positive pictures compared with neutral pictures (Mardaga and Hansenne, 2009b). Low‐HA adults seem to have automatic attention bias in positive picture processing and allocate more attentional resources to positive stimuli.…”
