Fairness perception and equality during social interactions frequently elicit affective arousal and affect decision making. By integrating the dictator game and a probabilistic gambling task, this study aimed to investigate the effects of a negative experience induced by perceived unfairness on decision making using behavioral, model fitting, and electrophysiological approaches. Participants were randomly assigned to the neutral, harsh, or kind groups, which consisted of various asset allocation scenarios to induce different levels of perceived unfairness...

Yumi Saito, Kazuo Okanoya
Emotional communication involves transmitting information on affective states. Rat 50- and 22-kHz ultrasonic vocalizations (USVs) are emotional communication signals that reflect positive or negative states, respectively. In general, emotional communication signals that elicit changes in event-related potentials (ERPs), suggesting a specific mechanism for processing these signals. As this is observed in several communication systems including humans, we hypothesized that rat USVs can also trigger such changes...

Facial expressions of emotion have an undeniable processing advantage over neutral faces, discernible both at behavioral level and in emotion-related modulations of several event-related potentials (ERPs). Recently it was proposed that also inherently neutral stimuli might gain salience through associative learning mechanisms. The present study investigated whether acquired motivational salience leads to processing advantages similar to biologically determined origins of inherent emotional salience by applying an associative learning paradigm to human face processing...

Objectives: Impairments in interpersonal relationships in depression present as irritability, pessimism, and withdrawal, and play an important role in the onset and maintenance of the disorder. However, we know little about the neurological causes of this impaired interpersonal function. This study used the event-related brain potential (ERP) version of the Cyberball paradigm to investigate the emotions and neural activities in depressive patients during social inclusion and exclusion simultaneously to explore neuropsychological mechanisms...

The purpose of the study was to compare event-related potentials (ERPs) to different transitions between emotional and neutral facial expressions. The stimuli contained a single transition between two different images of the same face, giving a strong impression of changing expression though apparent motion whilst eliminating change in irrelevant stimulus variables such as image contrast or identity. Stimuli were calibrated for intensity, valence and perceived emotion category and only trials where the target emotion was correctly identified were included...

Behavioral and electrophysiologic evidence suggests that major depression (MDD) involves right parietotemporal dysfunction, a region activated by arousing affective stimuli. Building on prior event-related potential (ERP) findings (Kayser et al. 2016 NeuroImage 142:337-350), this study examined whether these abnormalities also characterize individuals at clinical high risk for MDD. We systematically explored the impact of family risk status and personal history of depression and anxiety on three distinct stages of emotional processing comprising the late positive potential (LPP)...

Ja Y Lee, Kristen A Lindquist, Chang S Nam
There is debate about whether emotional granularity, the tendency to label emotions in a nuanced and specific manner, is merely a product of labeling abilities, or a systematic difference in the experience of emotion during emotionally evocative events. According to the Conceptual Act Theory of Emotion (CAT) (Barrett, 2006), emotional granularity is due to the latter and is a product of on-going temporal differences in how individuals categorize and thus make meaning of their affective states. To address this question, the present study investigated the effects of individual differences in emotional granularity on electroencephalography-based brain activity during the experience of emotion in response to affective images...

Reliable measures are required to draw meaningful conclusions regarding developmental changes in longitudinal studies. Little is known, however, about the test-retest reliability of face-sensitive event related potentials (ERPs), a frequently used neural measure in infants. The aim of the current study is to investigate the test-retest reliability of ERPs typically evoked by faces in 9-10 month-old infants. The infants (N=31) were presented with neutral, fearful and happy faces that contained only the lower or higher spatial frequency information...

The results of contemporary studies confirm the formation of two neural networks in the brain during the period of adolescence. The first is defined as emotional, located in the limbic system, develops earlier, quicker, and more intensively than the second one in the prefrontal cortex, called the judgement network, which fulfils the role of control and inhibition of emotional reactions. The domination of the emotional network in adolescence is manifested by hyperactivity of the limbic system, accompanied by intensified undertaking of courageous, reckless, risky, or even sometimes dangerous actions, so very characteristic in the maturation...

Congenital amusia is characterized by lifelong impairments in music perception and processing. It is unclear whether pitch detection deficits impact amusic individuals' perception of musical emotion. In the current work, 19 amusics and 21 healthy controls were subjected to electroencephalography (EEG) while being exposed to music excerpts and emotional faces. We assessed each individual's ability to discriminate positive- and negative-valenced emotional faces and analyzed electrophysiological indices, in the form of event-related potentials (ERPs) recorded at 32 sites, following exposure to emotionally positive or negative music excerpts...

Given finite attentional resources, how emotional aspects of stimuli are processed automatically is controversial. Present study examined the time-course for automatic processing of facial expression by assessing N170, and late positive potentials (LPPs) of event-related potentials (ERPs) using a modified rapid serial visual presentation (RSVP) paradigm. Observers were required to confirm a certain house image and to detect whether a face image was presented at the end of a series of pictures. There were no significant main effects on emotional type for P1 amplitudes, whereas happy and fearful expressions elicited larger N170 amplitudes than neutral expressions...

This study explored the temporal course of vocal and emotional sound processing. Participants detected rare repetitions in a stimulus stream comprising neutral and surprised nonverbal exclamations and spectrally rotated control sounds. Spectral rotation preserved some acoustic and emotional properties of the vocal originals. Event-related potentials (ERPs) elicited to unrepeated sounds revealed effects of voiceness and emotion. Relative to nonvocal sounds, vocal sounds elicited a larger centro-parietally distributed N1...

Huiyan Lin, Jing Xiang, Saili Li, Jiafeng Liang, Dongmei Zhao, Desheng Yin, Hua Jin
Previous studies have shown that uncertainty about the emotional content of an upcoming event modulates event-related potentials (ERPs) during the encoding of the event, and this modulation is affected by whether there are cues (i.e., cued uncertainty) or not (i.e., uncued uncertainty) prior to the encoding of the uncertain event. Recently, we showed that uncued uncertainty affected ERPs in later recognition of the emotional event. However, it is as yet unknown how the ERP effects of recognition are modulated by cued uncertainty...

Cognitive control enables successful goal-directed behavior by resolving a conflict between opposing action tendencies, while emotional control arises as a consequence of emotional conflict processing such as in irony. While negative emotion facilitates both cognitive and emotional conflict processing, it is unclear how emotional conflict processing is affected by positive emotion (e.g., humor). In 2 EEG experiments, we investigated the role of positive audiovisual target stimuli in cognitive and emotional conflict processing...

Task demands shape how we process environmental stimuli but their impact on the early neural processing of facial expressions remains unclear. In a within-subject design, ERPs were recorded to the same fearful, happy and neutral facial expressions presented during a gender discrimination, an explicit emotion discrimination and an oddball detection tasks, the most studied tasks in the field. Using an eye tracker, fixation on the face nose was enforced using a gaze-contingent presentation. Task demands modulated amplitudes from 200-350ms at occipito-temporal sites spanning the EPN component...

OBJECTIVE: To investigate the characteristics of working memory ability on emotional faces and related event-related potential (ERP) in children with autism spectrum disorder (ASD). METHODS: The Chinese Facial Affective Picture System was used as test material, and the event-related potential system was used to record the electroencephalographic data when 16 ASD children aged 6-12 years (ASD group) and 14 normal children matched for age (control group) were completing the facial emotion delayed match-to-sample task...

OBJECTIVE: Emotional and cognitive disturbances are common complications in Parkinson's disease (PD). N400 is an event related potential (ERP) strongly linked to lexical-semantic processing and has demonstrated alterations in amplitude and latency when PD patients performed semantic priming tasks. The present study investigated the role of N400 in an automatic affective priming paradigm in PD. Other ERP components relevant to emotion processing were also examined. METHOD: Twenty-two PD patients and 17 healthy adults performed an automatic affective priming task while ERPs were recorded using 128 channels...

The present event-related potential (ERP) study investigated for the first time whether children with early-onset social anxiety disorder (SAD) process affective facial expressions of varying intensities differently than non-anxious controls. Participants were 15 SAD patients and 15 non-anxious controls (mean age of 9 years). They were presented with schematic faces displaying anger and happiness at four intensity levels (25%, 50%, 75%, 100%), as well as with neutral faces. ERPs in early and later time windows (P100, N170, late positivity), as well as affective ratings (valence and arousal) for the faces, were recorded...

The ability of emotion regulation and emotional responses in children is a main component of emotional competence through the development process. We had employed electroencephalography (EEG) a well-known noninvasive method for recording of brain emotion signals in order to analyze the emotion regulations in children. The international affective picture system (IAPS) pictures dataset was used for selection of stimuli presentation. The stimulus presentation was commonly practiced to induce the emotional responses from human brain...

When two targets are presented within approximately 500 ms of each other in the context of rapid serial visual presentation (RSVP), participants' ability to report the second target is reduced compared to when the targets are presented further apart in time. This phenomenon is known as the attentional blink (AB). The AB is increased in magnitude when the first target is emotionally arousing. Emotionally arousing stimuli can also capture attention and create an AB-like effect even when these stimuli are presented as to-be-ignored distractor items in a single-target RSVP task...
