Margund K Rohr, Cornelia Wieck, Ute Kunzmann
Although various studies point to the importance of positive emotions for health and well-being across the entire life span, current research on age differences in emotional reactivity mainly focuses on negative emotions. Empirical evidence on positive emotions is scarce and mixed. Part of the inconsistencies may be related to study differences in the stimuli used and the emotional response systems considered. Thus, the present study examined different response systems (i.e., subjective feelings, facial and verbal expressions) and used internal stimuli of high personal relevance to all participants...

Toshinori Kaneshige, Etsuko Haryu
This study investigated infants' ability to use facial expressions to predict the expressers' subsequent cooperative behavior. To explore this problem, Experiment 1 tested 10- and 14-month-olds (N = 16, respectively) by using a violation-of-expectation procedure. In the experiment, all infants were first familiarized with two models, one with a happy facial expression and the other with an angry expression. They were also familiarized with an event in which a duck puppet tried to open a box but failed. During the test phase, infants in the helping condition saw two test scenes; one in which the happy model helped the duck open the box, and the other in which the angry model helped the duck...

Siyang Luo, Yiyi Zhu, Ying Xu, Qianting Kong
The oxytocinergic system is crucial for sociality and well-being and is associated with empathy. It is suggested that the oxytocinergic system exerts context- and person-dependent effects. We examined how sexual sadistic contexts influenced the effects of the oxytocinergic system on empathic-related behaviors and brain activity in healthy adults. Combining genetic neuroimaging, pharmacological techniques and a psychological paradigm of empathy, we recorded EEG neural responses in female OXTR rs53756 G/G and A/A carriers and measured subjective empathic ratings after intranasal administration of oxytocin/placebo in healthy male adults during the perception of painful facial expressions in sadistic/general social contexts...

A body of research has investigated the cognitive and affective features of imagining the future. Our study aimed at extending this research by evaluating expressions that are triggered by future thinking. Participants were asked to remember and to imagine personal events. Both past and future thinking were video-recorded and the recording was later analyzed by a software for facial analysis that detects and classifies basic emotional expressions (i.e., happy, sad, angry, surprised, scared, disgusted and neutral)...

According to embodiment theories, language and emotion affect each other. In line with this, several previous studies investigated changes in bodily responses including facial expressions, heart rate or skin conductance during affective evaluation of emotional words and sentences. This study investigates the embodiment of emotional word processing from a social perspective by experimentally manipulating the emotional valence of a word and its personal reference. Stimuli consisted of pronoun-noun pairs, i.e...

The ability to perceive a person's dominance plays an important role in survival and pro-social behavior. Perceived dominance has been investigated via assessments of facial expressions in 1-on-1 interaction situations, with expressions of anger and disgust judged to be more dominant. Given that human social interactions are complex, and multiple individuals interact at the same time, we investigated perceptions of trait dominance (an individual's competence and tendency to engage in dominant behavior) and relative dominance (an individual's social dominance within a social group)...

Deficient facial emotion recognition has been suggested to underlie aggression in individuals with antisocial personality disorder (ASPD). As the neuropeptide oxytocin (OT) has been shown to improve facial emotion recognition, it might also exert beneficial effects in individuals providing so much harm to the society. In a double-blind, randomized, placebo-controlled crossover trial, 22 individuals with ASPD and 29 healthy control (HC) subjects (matched for age, sex, intelligence, and education) were intranasally administered either OT (24 IU) or a placebo 45min before participating in an emotion classification paradigm with fearful, angry, and happy faces...

PURPOSE: Functional inoperability in advanced oral cancer is difficult to assess preoperatively. To assess functions of lips and tongue, biomechanical models are required. Apart from adjusting generic models to individual anatomy, muscle activation patterns (MAPs) driving patient-specific functional movements are necessary to predict remaining functional outcome. We aim to evaluate how volunteer-specific MAPs derived from surface electromyographic (sEMG) signals control a biomechanical face model...

The expression of emotion in faces serves numerous meaningful functions, such as conveying messages of danger or approach, facilitating communication, and promoting the formation of social bonds and relationships. The study of facial expressions of emotion has become integral to research in social psychology and social neuroscience, particularly with respect to the neuropeptide oxytocin. This chapter examines how oxytocin influences the processing of emotion in faces by reviewing intranasal administration studies of automatic processing, selective attention, and emotion recognition...

The analysis of high-dimensional, possibly temporally misaligned, time-varying visual data is a fundamental task in disciplines such as image, vision, and behaviour computing. In this paper, we focus on dynamic facial behaviour analysis and in particular on the analysis of facial expressions. Distinct from the previous approaches, where sets of facial landmarks are used for face representation, raw pixel intensities are exploited for 1) unsupervised analysis of the temporal phases of facial expressions and facial action unitis (AUs) and 2) temporal alignment of a certain facial behaviour displayed by two different persons...

BACKGROUND: Pain can be detected through nonverbal cues, including facial expressions, vocalisations, and body posture. While there are sex differences in how emotional expressions are recognized, these differences have not always been found for pain. One reason for this inconsistency may be methodological, as pain studies tend not to be designed to investigate individual differences in expression recognition. Also, few studies consider sex differences outside facial expression. METHODS: This study applied an image degradation method used to examine individual differences in emotion recognition, to investigate sex differences in the decoding of pain body postures...

We report 15 individuals with de novo pathogenic variants in WDR26. Eleven of the individuals carry loss-of-function mutations, and four harbor missense substitutions. These 15 individuals comprise ten females and five males, and all have intellectual disability with delayed speech, a history of febrile and/or non-febrile seizures, and a wide-based, spastic, and/or stiff-legged gait. These subjects share a set of common facial features that include a prominent maxilla and upper lip that readily reveal the upper gingiva, widely spaced teeth, and a broad nasal tip...

According to the recalibrational theory of anger, anger is a computationally complex cognitive system that evolved to bargain for better treatment. Anger coordinates facial expressions, vocal changes, verbal arguments, the withholding of benefits, the deployment of aggression, and a suite of other cognitive and physiological variables in the service of leveraging bargaining position into better outcomes. The prototypical trigger of anger is an indication that the offender places too little weight on the angry individual's welfare when making decisions, i...

The impact of borderline personality pathology on facial emotion recognition has been in dispute; with impaired, comparable, and enhanced accuracy found in high borderline personality groups. Discrepancies are likely driven by variations in facial emotion recognition tasks across studies (stimuli type/intensity) and heterogeneity in borderline personality pathology. This study evaluates facial emotion recognition for neutral and negative emotions (fear/sadness/disgust/anger) presented at varying intensities...

Brandy L Vanderbyl, Céline Gélinas
Behavioral scales allow for the pain assessment of vulnerable critically ill patients who are unable to self-report. However, validity of the use of such scales is limited in traumatic brain injury patients with an altered level of consciousness as a result of the different way that these patients express pain. Family participation is considered as an important component of pain assessment for those unable to self-report, but research in this area is minimal so far. This study aimed to describe what behaviors family caregivers deemed relevant to pain for patients with a traumatic brain injury with an altered level of consciousness in the intensive care unit...

Separate neural systems have been implicated in the recognition of facial identity and emotional expression. A growing number of studies now provide evidence against this modular view by demonstrating that integration of identity and emotion information enhances face processing. Yet, the neural mechanisms that shape this integration remain largely unknown. We hypothesize that the presence of both personal and emotional expression target information triggers changes in functional connectivity between frontal and extrastriate areas in the brain...

Kazunori Terada, Chikara Takeuchi
In the present study, we investigated whether expressing emotional states using a simple line drawing to represent a robot's face can serve to elicit altruistic behavior from humans. An experimental investigation was conducted in which human participants interacted with a humanoid robot whose facial expression was shown on an LCD monitor that was mounted as its head (Study 1). Participants were asked to play the ultimatum game, which is usually used to measure human altruistic behavior. All participants were assigned to be the proposer and were instructed to decide their offer within 1 min by controlling a slider bar...
