“…Secondly, it is possible that the negative pictures used in the present study were somehow too significant (i.e., highly significant contents and arousal ratings), so that possible personality differences cannot appear because of a ceiling effect. Hence it might be more appropriate to use less significant material (e.g., less arousing negative pictures or emotional words), since some studies have demonstrated that such stimuli are also able to elicit SCR (Silvert, Delplanque, Bouwalerh, Verpoort, & Sequeira, 2004). Thirdly, the choice to use only the TCI-R as a measure of personality may constitute a limitation, as other personality models have previously been linked to differential emotional reactivity differences.…”

Several studies found strong relationships between main personality dimensions and emotions, and more particularly between neuroticism and negative emotions, as well as between extraversion and positive ones. In these studies, personality was mainly assessed with respect to the big five model, and emotions were evaluated with subjective rating scales. To extend the exploration of the associations between personality and emotion, the aim of the present study was to investigate the relationships between Cloninger's dimensions of personality and emotional reactivity assessed by skin conductance response (SCR). In 55 normal subjects, SCR was recorded while they were presented pictures selected as positive, negative and neutral from the International Affective Picture System. The results showed no influence of personality on response magnitude, but subjects with higher harm avoidance scores showed longer half-recovery times for negative relative to neutral pictures. This result is consistent with the dispositional bias of harm avoidance to respond intensely to signals of aversive stimuli.

“…The privileged attentional capture of emotional stimuli can persist under spatio-temporal constraints very similar to those of peripheral vision, as showed by techniques of visual masking [21], very fast presentations [22,23] and binocular rivalry [24]. Indeed, Calvo and Lang [25] explored parafoveal vision at 10°of eccentricity and evidenced a preferential gaze attraction for emotional pictures when compared with neutral ones.…”

Recent findings from event-related potentials (ERPs) studies provided strong evidence that centrally presented emotional pictures could be used to assess affective processing. Moreover, several studies showed that emotionally charged stimuli may automatically attract attention even if these are not consciously identified. Indeed, such perceptive conditions can be compared to those typical of the peripheral vision, particularly known to have low spatial resolution capacities. The aim of the present study was to characterize at behavioral and neural levels the impact of emotional visual scenes presented in peripheral vision. Eighteen participants were asked to categorize neutral and unpleasant pictures presented at central (0°) and peripheral eccentricities (-30 and +30°) while ERPs were recorded from 63 electrodes. ERPs were analysed by means of spatio-temporal principal component analyses (PCA) in order to evaluate influences of the emotional content on ERP components for each spatial position (central vs. peripheral). Main results highlight that affective modulation of early ERP components exists for both centrally and peripherally presented pictures. These findings suggest that, for far peripheral eccentricities as for central vision, the brain engages specific resources to process emotional information.

“…Somatic emotional responses will be assessed by recording SCR, which is a classical and sensitive index of affective arousal [5,17], which directly reflects sympathetic nervous system activity (i.e. autonomic emotional response) and has been largely used in emotion research [32,33,42].…”

SummaryStudy aim. -Affective symptoms are major descriptors of depression; therefore, a lot of studies investigated emotional-responsiveness modulation in depression, and reported either a potentiation of negative affects, a reduction of positive affects, or a reduction of both positive and negative affects. On the other hand, personality was classically found to be modulated in depression, with behavioral inhibition system (BIS)-related dimensions (namely harm avoidance (HA), neuroticism) showing higher scores in depressed subjects. The aim of this study was to investigate the relationships between emotional responsiveness (as measured by skin conductance response [SCR]) and personality in depression. Methods. -SCR was recorded following the presentation of neutral, pleasant, and unpleasant pictures in 20 depressed subjects and 20 controls. Results. -Pleasant pictures elicited more and larger responses than unpleasant ones in control but not in depressed subjects. This effect was not modulated by personality. Moreover, depressed subjects were found to show generally faster half-recovery times and to rate emotional pictures as less arousing than control subjects and these effects disappeared when BIS-related dimensions were controlled. MOTS CLÉSDépression ; Personnalité ; Émotions ; Réponse électrodermale Résumé Objectifs. -Les symptômes affectifs sont des descripteurs majeurs de l'épisode dépressif ; pour cette raison, un grand nombre de travaux ont étudié les modulations de la réactivité émotion-nelle dans la dépression. Ils rapportent une potentialisation des affects négatifs, une diminution des affects positifs ou une réduction à la fois des affects positifs et négatifs. Par ailleurs, la personnalité est classiquement modulée dans la dépression, de sorte que les scores aux dimensions associées au système d'inhibition comportementale (SIC) (i.e. évitement du danger, neuroticisme) sont plus élevés chez les sujets déprimés. Le but de notre étude était d'investiguer les relations entre la réactivité émotionnelle (mesurée par la réponse électrodermale [RED]) et la personnalité dans la dépression. Méthodes. -La RED a été enregistrée suite à la présentation d'images neutres, plaisantes et déplaisantes chez 20 sujets déprimés et 20 sujets contrôles. Résultats. -Les images plaisantes provoquent plus de réponses et des réponses plus amples que les images déplaisantes chez les sujets contrôles mais pas chez les déprimés. Cet effet n'est pas modulé par la personnalité. Par ailleurs, les sujets déprimés montrent des temps de récupération plus courts et jugent les images émotionnelles comme associées à un éveil émotionnel moindre que les sujets contrôles et ces effets disparaissent lorsque les dimensions associées au SIC sont contrôlées. Conclusions. -Ces résultats suggèrent que les dimensions associées au SIC sont indépendantes de la diminution sélective des réponses aux images plaisantes mais sont impliquées dans la réduction globale observée des affects.
