Depression is related to the defect of emotion processing, and people's emotional processing is crossmodal. This article aims to investigate whether there is a difference in audiovisual emotional integration between the depression group and the normal group using a high-resolution event-related potential (ERP) technique. We designed a visual and/or auditory detection task. The behavioral results showed that the responses to bimodal audiovisual stimuli were faster than those to unimodal auditory or visual stimuli, indicating that crossmodal integration of emotional information occurred in both the depression and normal groups. The ERP results showed that the N2 amplitude induced by sadness was significantly higher than that induced by happiness. The participants in the depression group showed larger amplitudes of N1 and P2, and the average amplitude of LPP evoked in the frontocentral lobe in the depression group was significantly lower than that in the normal group. The results indicated that there are different audiovisual emotional processing mechanisms between depressed and non-depressed college students.

Objective. To assess the ability of Alzheimer's disease (AD) patients to perceive emotional information and to assign subjective emotional rating scores to audiovisual presentations.Materials and Methods. 24 subjects (14 with AD, matched to controls for age and educational levels) were studied. After neuropsychological assessment, they watched a Neutral story and then a story with Emotional content.Results. Recall scores for both stories were significantly lower in AD (Neutral and Emotional:P=.001). CG assigned different emotional scores for each version of the test,P=.001, while ratings of AD did not differ,P=.32. Linear regression analyses determined the best predictors of emotional rating and recognition memory for each group among neuropsychological tests battery.Conclusions. AD patients show changes in emotional processing on declarative memory and a preserved ability to express emotions in face of arousal content. The present findings suggest that these impairments are due to general cognitive decline.

Electrophysiological Mechanism

In the natural environment, facial and bodily expressions influence each other. Previous research has shown that bodily expressions significantly influence the perception of facial expressions. However, little is known about the cognitive processing of facial and bodily emotional expressions and its temporal characteristics. Therefore, this study presented facial and bodily expressions, both separately and together, to examine the electrophysiological mechanism of emotional recognition using event-related potential (ERP). Participants assessed the emotions of facial and bodily expressions that varied by valence (positive/negative) and consistency (matching/non-matching emotions). The results showed that bodily expressions induced a more positive P1 component and a shortened latency, whereas facial expressions triggered a more negative N170 and prolonged latency. Among N2 and P3, N2 was more sensitive to inconsistent emotional information and P3 was more sensitive to consistent emotional information. The cognitive processing of facial and bodily expressions had distinctive integrating features, with the interaction occurring in the early stage (N170). The results of the study highlight the importance of facial and bodily expressions in the cognitive processing of emotion recognition.

Emotional Information Processing

Implicit motives play an important role in the regulation of many basic cognitive processes, particularly in the stage of attention. We conducted a study with a sample of 58 college students to examine selective attention to emotional stimuli as a function of individual differences in the implicit need for affiliation (nAff). In an affective oddball paradigm, event-related potentials were recorded while participants viewed positive, neutral, and negative images of people. Results showed that individuals high in nAff elicited larger late positive potential amplitudes to negative images than those low in nAff did. These findings replicate and extend the results of a previous study focused on these relationships and provide additional information on the neural correlates of affiliation-related emotional information processing.

IntroductionUnaffected healthy 1st degree relatives of patients with major depressive disorder (MDD) are 3.6 times more liable to develop the disease themselves than the standard population without the history of the disorder. Neural correlates of this liability are of particular interest since the phenomenon does not always have behavioral manifestations and early detected can enhance quicker and better MDD prevention.ObjectiveThe objective of our study was to establish neuronal correlates of susceptibility MDD in unaffected healthy 1st degree relatives of patients with MDD. Inhibition of emotional information was examined in the present study.AimsThe aim of the study was to better understand the development of MDD and the role of altered inhibition of emotional processing in it. That, in consequence, may contribute to establishing new methods of prevention and quicker detection of MDD liability.MethodsTwenty-one unaffected healthy 1st degree relatives of patients with MDD and twenty-five matched healthy controls underwent a functional magnetic resonance imaging procedure with a task involving inhibition of emotional processing of positive, negative and neutral emotional information. 2 × 3 ANOVA was performed to establish if the two groups differed significantly in the inhibition of one of the three types of emotions.ResultsThe unaffected healthy 1st degree relatives displayed an increased neural activation during the inhibition of negative emotional information in the bilateral middle cingulate cortex (MCC) and the left caudate nucleus (p< 0.05, family wise error).ConclusionsThe overactivation of the MCC and caudate nucleus can be a marker of MDD liability

More often than not, emotion perception is a process guided by several sensory channels, accompanied by multimodal integration of emotional information. This process appears vital for effective social communication. This chapter provides an overview of recent studies describing the crossmodal integration of non-verbal emotional cues communicated via voices, faces, and bodies. The first parts of the chapter deal with the behavioural and neural correlates of multimodal integration in the healthy population using psychophysiological, electrophysiological, and neuroimaging measures, highlighting a network of brain areas involved in this process and discussing different methodological approaches. The final parts of the chapter, in contrast, are dedicated to the alterations of the multisensory integration of non-verbal emotional signals in states of psychiatric disease, with the main focus on schizophrenia and autism spectrum disorders.

In the field of time psychology, the functional significance of the contingent negative variation (CNV) component in time perception and whether the processing mechanisms of sub- and supra-second are similar or different still remain unclear. In the present study, event-related potential (ERP) technology and classical temporal discrimination tasks were used to explore the neurodynamic patterns of sub- and supra-second time perception. In Experiment 1, the standard interval (SI) was fixed at 500 ms, and the comparison interval (CI) ranged from 200 ms to 800 ms. In Experiment 2, the SI was fixed at 2000 ms, and the CI ranged from 1400 ms to 2600 ms. Participants were required to judge whether the CI was longer or shorter than the SI. The ERP results showed similar CNV activity patterns in the two experiments. Specifically, CNV amplitude would be more negative when the CI was longer or closer to the memorized SI. CNV peak latency increased significantly until the CI reached the memorized SI. We propose that CNV amplitude might reflect the process of temporal comparison, and CNV peak latency might represent the process of temporal decision-making. To our knowledge, it is the first ERP task explicitly testing the two temporal scales, sub- and supra-second timing, in one study. Taken together, the present study reveals a similar functional significance of CNV between sub- and supra-second time perception.

The present study examines the unconscious influence of emotional information on decision making in a simulated hiring situation. We used a subliminal masked priming paradigm with varying faces as primes, which were presented for a duration of 50 ms and had two levels of emotion: positive emotion (happiness) and negative emotion (anger). These primes were followed by emotionally neutral target faces. Primes were congruent (same faces) or incongruent (different faces). Prime Emotion (positive vs. negative) was crossed with Prime Repetition (repeat vs. unrelated) in a 2 × 2 factorial design. Each participant was tested in all four of the experimental conditions, each of which had 5 different trials. The participants were asked to indicate as rapidly as possible whether they were “favorable” or “unfavorable” toward the selection of the candidate (target face). Two dependent measures were analyzed: number of target faces chosen (i.e., number of “favorable” responses to target faces) and reaction time (RT). Results revealed a strong effect of emotional priming. Participants tended to choose more target faces preceded by positive prime faces than by negative prime faces. Moreover, they reacted faster when presented with target faces preceded by negative primes. Despite its exploratory nature, this study provides further evidence for the role of emotional processing in modulating decision processes and extends the experimental manipulation of subliminal emotion to the case of the masked repetition priming technique.
