“…Several previous studies reported that P300 amplitude depends (among other parameters) on personal relevance of the information, including its emotional aspect [1,19,35]. Thus, using a three-stimulus visual oddball protocol with emotional pictures as the novel stimulus, Delplanque et al [19] reported an increase in P300 amplitude for pleasant and unpleasant novel stimuli relative to neutral novel ones, which indicates that attentional processes indexed by P300 are influenced by emotional valence and arousal characteristics of information.…”

“…Emotional pictures consisted of 75 coloured pictures selected as neutral, pleasant and unpleasant (25 in each category) from the International Affective Picture System (IAPS [33]) 1 . The slides were displayed on a 17-inch computer screen (1400*1050 pixels, rate of refreshment 60 Hz) at a one meter distance from the subject.…”

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.

“…Based on the observation in previous work that users respond in measurable ways to visual stimuli [6], we have recently recorded the responses of small groups of viewers watching a wide range of movies using the BodyMedia device and heart rate monitors. As an example of the initial output of this work, Figures 1 and 2 show the GSR response of two viewers of the first 10 minutes of the film Finding Nemo.…”

“…Using these measurements studies have demonstrated a number of results of potential relevance in IR. For example, using machine learning, models can be built that enable a predefined group of emotional states to be recognized with good reliability [4], a user's frustration response to interacting with a poorly performing computer application can be recognised [5], and variations in physiological responses to different images presentation to a user can be captured [6].…”

Abstract. Current information retrieval systems make no measurement of the user's response to the searching process or the information itself. Existing psychological studies show that subjects exhibit measurable physiological responses when carrying out certain tasks, e.g. when viewing images, which generally result in heightened emotional states. We find that users exhibit measurable biometric behaviour in the form of galvanic skin response when watching movies, and engaging in interactive tasks. We examine how this data might be exploited in the indexing of data for search and within the search process itself.
