“…Intriguingly, in this latter study, the occipital negativity associated with the detection of task-relevant stimulus features was accompanied by a frontal positivity, which is highly consistent with the pattern in the present study. The frontal and parietal modulations in the N200 and P300 time range, respectively, are furthermore in line with studies in which participants encountered affective stimulus material [e.g., [31], [33], [34], [35]] and in reward paradigms investigating ERP responses to reward-predicting cues, as well as to rewarded target stimuli [16], [18]–[20]. Moreover, similar modulations in the N200/P300 range are commonly observed in studies focusing on reward feedback [e.g., [17], [36]].…”

Reward Associations Reduce Behavioral Interference by Changing the Temporal Dynamics of Conflict Processing

Associating stimuli with the prospect of reward typically facilitates responses to those stimuli due to an enhancement of attentional and cognitive-control processes. Such reward-induced facilitation might be especially helpful when cognitive-control mechanisms are challenged, as when one must overcome interference from irrelevant inputs. Here, we investigated the neural dynamics of reward effects in a color-naming Stroop task by employing event-related potentials (ERPs). We found that behavioral facilitation in potential-reward trials, as compared to no-reward trials, was paralleled by early ERP modulations likely indexing increased attention to the reward-predictive stimulus. Moreover, reward changed the temporal dynamics of conflict-related ERP components, which may be a consequence of an early access to the various stimulus features and their relationships. Finally, although word meanings referring to potential-reward colors were always task-irrelevant, they caused greater interference compared to words referring to no-reward colors, an effect that was accompanied by a relatively early fronto-central ERP modulation. This latter observation suggests that task-irrelevant reward information can undermine goal-directed behavior at an early processing stage, presumably reflecting priming of a goal-incompatible response. Yet, these detrimental effects of incongruent reward-related words were absent in potential-reward trials, apparently due to the prioritized processing of task-relevant reward information. Taken together, the present data demonstrate that reward associations can influence conflict processing by changing the temporal dynamics of stimulus processing and subsequent cognitive-control mechanisms.

“…Focused on emotional arousal, some studies have demonstrated that highly emotionally arousing stimuli elicit more pronounced P300 waves than low emotionally arousing stimuli, even when these stimuli are presented without awareness (Feng, Wang, Liu, Zhu, Dai, Mai, & Luo, 2012;Rozenkrants, Olofsson, & Polich, 2008). These previous findings are in accord with the current study, confirming that emotional arousal increases P300 responses to probes in the CIT, regardless of conscious awareness.…”

“…Thus, it remains unclear whether crime-related stimuli are also automatically recognized in the CIT, like selfname stimuli. Previous studies have demonstrated that highly emotionally arousing stimuli elicit more pronounced P300 waves than less emotionally arousing stimuli, even when these stimuli are presented without conscious recognition (Feng, Wang, Liu, Zhu, Dai, Mai, & Luo, 2012;Rozenkrants, Olofsson, & Polich, 2008). In line with these studies, a crime-related probe might also be processed via the bottom-up route if it is perceived unconsciously.…”

The Concealed Information Test (CIT) is an information-detecting technique for criminal investigations. Although it has been shown that emotional arousal plays a specific role in the CIT, the mechanisms by which emotional arousal affects the CIT are unclear. The main purpose of this study was to elucidate the processing pathway for stimuli encoded with emotional arousal in a mock crime before the CIT. In this study, participants viewed emotionally arousing pictures before the mock crime. Participants were assigned randomly to either a high or low emotional arousal group, viewing pictures expected to arouse emotion at a high or low level, respectively. Subsequently, all participants enacted the same mock crime, in which they were instructed to stab a pillow with a sharp-edged tool (e.g., kitchen knife or ice pick) as if to harass a woman lying on a bed. After the antecedent emotional experience, a P300-based CIT was conducted using subliminal and supraliminal presentation methods. The results revealed a significantly greater CIT effect on the P300 event-related potential (ERP) component in the High Arousal group compared with the Low Arousal group, under both subliminal and supraliminal conditions. The detection of concealed information was successful only in the High Arousal group under subliminal conditions, whereas detection was successful regardless of the emotional arousal group under supraliminal conditions. These results provide strong evidence that emotional arousal can increase P300 amplitude during responses to concealed information in the CIT. This suggests that concealed information may be automatically processed via the bottom-up route in the CIT, but only when it is encoded with high emotional arousal.

“…Our result is consistent with their finding of P2, which was elicited differently by beautiful and less beautiful pendants. Many previous ERP studies have provided evidence that emotional content in pictures (if it existed) was still evaluated even in an implicit nonemotional task and different emotions were reflected in the difference in P2 amplitude [16,17,23]. These findings supported the point that early emotional evaluation is an automatic process [24].…”

The present study explored the implicit aesthetic processing of different architectures using an event-related potential method. Event-related potential data were acquired in a categorization task in which participants were asked to distinguish between two different categories of pictures of everyday life objects and the architectures as soon as possible. The architectural pictures included two categories: noted-architect-designed and ordinary architectures. A smaller P2 amplitude and a larger N2 amplitude were elicited by the master architects' works than those of ordinary architectures, which indicated that perceived positive emotion and novelty perception occurred in the aesthetic processing of architectures. Our results present two sensitive neural indicators, P2 and N2, to judge the delight and novelty qualities shown by the architecture, respectively.
