Background: Responses to external emotional-stimuli or their transitions might help to elucidate the scientific background and assist the clinical management of psychiatric problems, but pure emotional-materials and their utilization at different levels of neurophysiological processing are few. Objective: We aimed to describe the responses at central and peripheral levels in healthy volunteers and psychiatric patients when facing external emotions and their transitions. Methods: Using pictures and sounds with pure emotions of Disgust, Erotica, Fear, Happiness, Neutral, and Sadness or their transitions as stimuli, we have developed a series of non-invasive techniques, i.e., the event-related potentials, functional magnetic resonance imaging, excitatory and inhibitory brainstem reflexes, and polygraph, to assess different levels of neurophysiological responses in different populations. Results: Sample outcomes on various conditions were specific and distinguishable at cortical to peripheral levels in bipolar I and II disorder patients compared to healthy volunteers. Conclusions: Methodologically, designs with these pure emotions and their transitions are applicable, and results per se are specifically interpretable in patients with emotion-related problems.

The present study investigated the interaction of emotional prosody and word valence during emotional comprehension in men and women. In a prosody-word interference task, participants listened to positive, neutral, and negative words that were spoken with a happy, neutral, and angry prosody. Participants were asked to rate word valence while ignoring emotional prosody, or vice versa. Congruent stimuli were responded faster and more accurately as compared to incongruent emotional stimuli. This behavioral effect was more salient for the word valence task than for the prosodic task and was comparable between men and women. The event-related potentials (ERPs) revealed a smaller N400 amplitude for congruent as compared to emotionally incongruent stimuli. This ERP effect, however, was significant only for the word valence judgment and only for female listeners. The present data suggest that the word valence judgment was more difficult and more easily influenced by task-irrelevant emotional information than the prosodic task in both men and women. Furthermore, although emotional prosody and word valence may have a similar influence on an emotional judgment in both sexes, ERPs indicate sex differences in the underlying processing. Women, but not men, show an interaction between prosody and word valence during a semantic processing stage.

Abstract Background: Cognitive impairments have been reported in patients with pituitary adenoma; however, there is a lack of knowledge of investigating the emotional stimuli processing in pituitary patients. Thus, we aimed to investigate whether there is emotional processing dysfunction in pituitary patients by recording and analyzing the late positive potential (LPP) elicited by affective stimuli.Methods: Evaluation of emotional stimuli processing by LPP Event related potentials (ERPs) was carried out through central- parietal electrode sites (C3, Cz, C4, P3, Pz, P4) on the head of the patients and healthy controls (HCs).Results: In the negative stimuli, the amplitude of LPP was 2.435 ± 0.419μV for HCs and 0.656 ± 0.427μV for patient group respectively ( p = 0.005). In the positive stimuli, the elicited electric potential 1.450 ± 0.316μV for HCs and 0.495 ± 0.322μV for patient group respectively ( p = 0.040). Moreover, the most obvious difference of LPP amplitude between the two groups existed in the right parietal region. On the right hemisphere (at the P4 site), the elicited electric potential was 1.993 ± 0.299μV for HCs and 0.269 ± 0.305μV for patient group respectively( p = 0.001).Conclusion: There are functional dysfunction of emotional stimuli processing in pituitary adenoma patients. Our research provides the electrophysiological evidence for the presence of cognitive dysfunction which need to be intervened in the pituitary adenoma patients.

Duration Estimation

Abstract Emotional stimuli like emotional faces have been frequently shown to be temporally overestimated compared to neutral ones. This effect has been commonly explained by induced arousal caused by emotional processing leading to the acceleration of an inner-clock-like pacemaker. However, there are some studies reporting contradictory effects and others point to relevant moderating variables. Given this controversy, we aimed at investigating the processes underlying the temporal overestimation of emotional faces by combining behavioral and electrophysiological correlates in a temporal bisection task. We assessed duration estimation of angry and neutral faces using anchor durations of 400 ms and 1600 ms while recording event-related potentials. Subjective ratings and the early posterior negativity confirmed encoding and processing of stimuli’s emotionality. However, temporal ratings did not differ between angry and neutral faces. In line with this behavioral result, the Contingent Negative Variation (CNV), an electrophysiological index of temporal accumulation, was not modulated by the faces’ emotionality. Duration estimates, i.e., short or long responses toward stimuli of ambiguous durations of 1000 ms, were nevertheless associated with a differential CNV amplitude. Interestingly, CNV modulation was already observed at 600–700 ms after stimulus onset, i.e., long before stimulus offset. The results are discussed in light of the information-processing model of time perception as well as regarding possible factors of the experimental setup moderating temporal overestimation of emotional stimuli. In sum, combining behavioral and electrophysiological measures seems promising to more clearly understand the complex processes leading to the illusion of temporal lengthening of emotional faces.

Using P300-based brain–computer interfaces (BCIs) in daily life should take into account the user’s emotional state because various emotional conditions are likely to influence event-related potentials (ERPs) and consequently the performance of P300-based BCIs. This study aimed at investigating whether external emotional stimuli affect the performance of a P300-based BCI, particularly built for controlling home appliances. We presented a set of emotional auditory stimuli to subjects, which had been selected for each subject based on individual valence scores evaluated a priori, while they were controlling an electric light device using a P300-based BCI. There were four conditions regarding the auditory stimuli, including high valence, low valence, noise, and no sound. As a result, subjects controlled the electric light device using the BCI in real time with a mean accuracy of 88.14%. The overall accuracy and P300 features over most EEG channels did not show a significant difference between the four auditory conditions (p > 0.05). When we measured emotional states using frontal alpha asymmetry (FAA) and compared FAA across the auditory conditions, we also found no significant difference (p > 0.05). Our results suggest that there is no clear evidence to support a hypothesis that external emotional stimuli influence the P300-based BCI performance or the P300 features while people are controlling devices using the BCI in real time. This study may provide useful information for those who are concerned with the implementation of a P300-based BCI in practice.

Inhibitory control, the ability to stop or prevent an action, is of relevance to disorders marked by increased disinhibition and impulsivity, including some facets of psychopathy. Because aspects of cognitive control (including inhibitory control) and emotion are theorized to compete for processing resources, emotional conditions may exacerbate aggressive, impulsive, and potentially harmful behaviors. The present study examined relationships between specific facets of psychopathy and inhibitory control in the context of positive, negative, and neutral emotional stimuli in a community sample using event-related potentials during an emotional-linguistic Go/No-Go task. Results indicated distinct cognition-emotion interactions for each facet of psychopathy. High scorers on the interpersonal facet exhibited decreased inhibitory processing in the presence of emotional stimuli, and decreased emotional processing in the presence of inhibitory demands, suggesting reciprocal interference between cognition and emotion. Higher scores on the callous affect facet were associated with lower emotion and inhibition processing, except when stimuli were most engaging (emotional No-Go trials). Higher lifestyle facet scores related to reciprocal facilitation between inhibition and emotion processing. Finally, higher scores on the antisocial facet were associated with poorer behavioral inhibition overall. Results provide novel evidence for interactions between affective processing and cognitive control among individuals high on distinct psychopathic traits.

The Relationship

Using the emotion-priming paradigm, we examined the neural mechanisms underlying the relationship between subjective well-being (SWB) and the processing of emotional stimuli by recording event-related potentials relevant to emotion probe words. The positive words were classified faster and more accurately by both low- and high-level SWB (very happy and not very happy) groups. Late positive potential (LPP) amplitudes elicited by emotional words were compared with words elicited in the neutral priming condition, and we found LPPs significantly reduced under the fear-inducing priming condition. This priming effect was more prominent in the group of participants who were not very happy, showing that, compared to the very happy group, these participants were more sensitive and subject to the influence of external stimuli (particularly negative emotional stimuli). The findings provide electrophysiological evidence for the relationship between SWB and emotion processing.

Subliminal Stimulation

Several cortical and subcortical brain areas have been reported to be sensitive to the emotional content of subliminal stimuli. However, the timing of these activations remains unclear. Our scope was to detect the earliest cortical traces of visual unconscious processing by recording event-related potentials (ERPs) from 43 participants. Subliminal spiders (emotional) and wheels (neutral), sharing similar low-level visual parameters, were presented at two different locations (fixation and periphery). The differential (peak to peak) amplitude from CP1 (77 milliseconds from stimulus onset) to C2 (100 milliseconds), two early visual ERP components originated in V1/V2 according to source localization analyses, was analyzed via Bayesian and traditional analyses. Spiders elicited greater CP1-C2 amplitudes than wheels when presented at fixation. This fast effect of subliminal stimulation -not reported previously to the best of our knowledge- has implications in several debates: i) the amygdala cannot be mediating these effects, ii) latency of other evaluative structures recently proposed, such as the visual thalamus, is compatible with these results, iii) the absence of peripheral stimuli effects points to a relevant role of the parvocellular visual system in unconscious processing.

Abstract BackgroundSocial impairment is a defining phenotypic feature of autism. The present study investigated whether individuals with autistic traits exhibit altered perceptions of social emotions. MethodsTwo groups of participants (High-AQ and Low-AQ) were recruited based on their scores on the autism-spectrum quotient (AQ). Their behavioral responses and event-related potentials (ERP) elicited by social and nonsocial stimuli with positive, negative, and neutral emotional valence were compared in two experiments. In Experiment 1, participants were instructed to view social-emotional and nonsocial-emotional pictures. In Experiment 2, participants were instructed to listen to social-emotional and nonsocial-emotional audio recordings. ResultsMore negative emotional reactions and smaller amplitudes of late ERP components (the late positive potential in Experiment 1 and the late negative component in Experiment 2) were found in the High-AQ group than in the Low-AQ group in response to the social-negative stimuli. In addition, amplitudes of these late ERP components in both experiments elicited in response to social-negative stimuli were correlated with the AQ scores of the High-AQ group. LimitationsAlthough the influence of autistic traits on reactions to social or nonsocial emotional stimuli was assessed in an experimental setting, whether and how these reactions are related to real-world behavior requires further investigation. In addition, filler trials should be used to evaluate whether participants focused sufficiently on the emotional stimuli. ConclusionThese results suggest that individuals with autistic traits have altered emotional processing of social-negative emotions.
