RESUMO

Moral framing and reframing strategies persuade people holding moralized attitudes (i.e., attitudes having a moral basis). However, these strategies may have unintended side effects: They have the potential to moralize people's attitudes further and as a consequence lower their willingness to compromise on issues. Across three experimental studies with adult U.S. participants (Study 1: N = 2,151, Study 2: N = 1,590, Study 3: N = 1,015), we used persuasion messages (moral, nonmoral, and control) that opposed new big-data technologies (crime-surveillance technologies and hiring algorithms). We consistently found that moral frames were persuasive and moralized people's attitudes, whereas nonmoral frames were persuasive and de-moralized people's attitudes. Moral frames also lowered people's willingness to compromise and reduced behavioral indicators of compromise. Exploratory analyses suggest that feelings of anger and disgust may drive moralization, whereas perceiving the technologies to be financially costly may drive de-moralization. The findings imply that use of moral frames can increase and entrench moral divides rather than bridge them.

RESUMO

Facial color is thought to contribute to the perception of emotional expression. Previous studies on facial recognition have shown that reddish and bluish faces enhance the perceptions of anger and sadness, respectively. However, the effect of facial color on the recognition of facial expressions in the range of natural skin colors remains unexplored. In this study, we examined the effect of natural skin color changes on the perception of facial expressions of anger, sadness, and happiness. We used five skin color conditions for each facial expression: standard, and hemoglobin or melanin decrease/increase (H-, H+, M-, and M + ). In the experiment, we used images of different facial expressions ranging from neutral to maximum intensity. Observers judged whether a face stimulus was perceived as "angry" ("happy" or "sad") or "not angry" ("not happy" or "not sad"). The results showed that H+, M+, H-, and M- enhanced the perception of anger and happiness, respectively. However, the change in the perception of sadness due to these modulations was small. These results suggest that the range of natural facial colors by hemoglobin and melanin modulation affects facial expression recognition. We further consider the possibility that these results could be partially explained by the lightness of the stimulus.

RESUMO

Emotion recognition is defined as identifying human emotion and is directly related to different fields such as human-computer interfaces, human emotional processing, irrational analysis, medical diagnostics, data-driven animation, human-robot communication, and many more. This paper proposes a new facial emotional recognition model using a convolutional neural network. Our proposed model, "ConvNet", detects seven specific emotions from image data including anger, disgust, fear, happiness, neutrality, sadness, and surprise. The features extracted by the Local Binary Pattern (LBP), region based Oriented FAST and rotated BRIEF (ORB) and Convolutional Neural network (CNN) from facial expressions images were fused to develop the classification model through training by our proposed CNN model (ConvNet). Our method can converge quickly and achieves good performance which the authors can develop a real-time schema that can easily fit the model and sense emotions. Furthermore, this study focuses on the mental or emotional stuff of a man or woman using the behavioral aspects. To complete the training of the CNN network model, we use the FER2013 databases at first, and then apply the generalization techniques to the JAFFE and CK+ datasets respectively in the testing stage to evaluate the performance of the model. In the generalization approach on the JAFFE dataset, we get a 92.05% accuracy, while on the CK+ dataset, we acquire a 98.13% accuracy which achieve the best performance among existing methods. We also test the system's success by identifying facial expressions in real-time. ConvNet consists of four layers of convolution together with two fully connected layers. The experimental results show that the ConvNet is able to achieve 96% training accuracy which is much better than current existing models. However, when compared to other validation methods, the suggested technique was more accurate. ConvNet also achieved validation accuracy of 91.01% for the FER2013 dataset. We also made all the materials publicly accessible for the research community at: https://github.com/Tanoy004/Emotion-recognition-through-CNN .

RESUMO

A recent event-related potential (ERP) study found that an open-label placebo (OLP) reduced emotional distress during the viewing of unpleasant scenes and the amplitude of the late positive potential (LPP). The present ERP experiment aimed at a conceptual replication of this finding and investigated OLP effects during affective face processing. The participants (109 females) were presented with images depicting angry and neutral facial expressions after the administration of a saline nasal spray. The spray was either introduced as a placebo that could help reduce the emotional reactions to viewing angry faces (OLP group) or to improve the electrophysiological recordings (Control group). The OLP was associated with reduced LPP amplitudes (1000-6000 ms) to anger expressions across a frontal cluster. Additionally, the OLP reduced LPP amplitudes (400-1000 ms) to both anger and neutral faces across a centroparietal cluster. Compared to the Control group, the OLP group reported less arousal when confronted with angry faces, and rated the anger expressions as less intense. This study demonstrates that an OLP can alter both subjective and neural responses to anger cues. Future research should directly compare OLP treatment with other strategies for emotion regulation (e.g., cognitive reappraisal) to demonstrate the specificity of this approach.

RESUMO

Previous studies suggested that childhood maltreatment was associated with cyberbullying. However, it's not clear the internal cognitive processes of how maltreatment causes cyberbullying. Therefore, the current study aims to explore the effect of childhood maltreatment on cyberbullying and the mediating effects of hostile attribution bias and anger rumination. A sample of 528 college students completed the measures of childhood maltreatment, cyberbullying, hostile attribution bias, and anger rumination. Multiple mediation analysis and bootstrapping showed that hostile attribution bias and anger rumination mediated the link between child maltreatment and cyberbullying. The results of this study suggested that childhood maltreatment increased the risk of cyberbullying, which was caused by a co-effect of hostile attribution bias and anger rumination, and it provides an intervention direction for effectively preventing the cyberbullying in abused individuals.

RESUMO

BACKGROUND: The idea that attachment styles can affect the level of anger in an individual educes a reason why people develop anger issues and behavioral problems in adolescence that escalate into adulthood. Lebanon suffers from a shortage of data pertaining to insecure attachment styles and the affective and cognitive aspects of anger and behavioral anger expression among the Lebanese youth population. This study aimed to investigate the association between attachment dimensions and anger expression (trait anger, hostility, physical aggression, and verbal aggression) among a sample of Lebanese adolescent participants. METHODS: This cross-sectional study was performed between January and May 2019 among 1810 Lebanese high-school students aged 12-18 and used two validated measures, the Adolescent-Relationship Questionnaire (A-RQ) and The Buss-Perry Aggression Questionnaire (BPAQ). The A-RQ assessed attachment behaviors, while the BPAQ evaluated aggression. RESULTS: Higher fearful and dismissing attachment styles, and higher physical activity index were significantly associated with higher physical and verbal aggression. A higher fearful attachment style was significantly associated with more anger. A higher secure attachment style was significantly associated with less anger. Higher preoccupied and dismissing attachment styles were significantly associated with higher hostility. CONCLUSION: Our findings revealed a significant relationship between both insecure attachment dimensions and the tripartite model of anger expression. This study adds to the anger literature by providing a more informed understanding of how variations in anger expression are linked to the processing of interpersonal interactions, which are the hidden facets of attachment systems.

RESUMO

BACKGROUND: The epidemic of Zika virus (ZIKV) was associated with a sudden and unprecedented increase in infants born with microcephaly. Colombia was the second most affected country by the epidemic in the Americas. Primary caregivers of children with ZIKV-associated microcephaly, their mothers mainly, were at higher risk of suffering anxiety and depression. Often, these women were stigmatized and abandoned by their partners, relatives, and communities. METHODOLOGY/PRINCIPAL FINDINGS: This study aimed to understand the perceptions about ZIKV infection among mothers of children born with microcephaly during the ZIKV epidemic in Caribbean Colombia, and the barriers and facilitators affecting child health follow-up. An exploratory qualitative study, based on Phenomenology and Grounded Theory, was conducted in Caribbean Colombia. Data were collected through In-Depth Interviews (IDI) from women who delivered a baby with microcephaly during the ZIKV epidemic at Clínica Salud Social, Sincelejo, Sucre District (N = 11). The themes that emerged during the interviews included experiences from their lives before pregnancy; knowledge about ZIKV; experiences and perceptions when diagnosed; considering a possible termination of pregnancy, and children's clinical follow-up. In some cases, women reported having been told they were having a baby with microcephaly but decided not to terminate the pregnancy; while in other cases, women found out about their newborn's microcephaly condition only at birth. The main barriers encountered by participants during children's follow-up included the lack of psychosocial and economic support, the stigmatization and abandonment by some partners and relatives, and the frustration of seeing the impaired development of their children. CONCLUSIONS: This study contributed to identifying the social, medical, psychological, and economic needs of families with children affected by the ZIKV epidemic. Commitment and action by local and national governments, and international bodies, is required to ensure sustained and quality health services by affected children and their families.

RESUMO

Public transport systems have a vital role in achieving sustainable mobility goals, diminishing reliance on private individual transport and improving overall public health. Despite that, transport operators are often in situations that require them to cope with complex working conditions that lead to negative emotions such as anger. The current study represents a segment of the permanent global research agenda that seeks to devise and test a psychometric scale for measuring driving anger in professional drivers. The present research is one of the first attempts to examine the factorial validity and the cross-cultural measurement equivalence of the broadly utilized Driving Anger Scale (DAS) in three culturally different countries within the Western Balkans region. The respondents (N = 1054) were taxi, bus and truck drivers between 19 and 75 years of age. The results pertaining to confirmatory factor analysis showed that there were adequate fit statistics for the specified six-dimensional measurement model of the DAS. The measurement invariance testing showed that the meaning and psychometric performance of driving anger and its facets are equivalent across countries and types of professional drivers. Furthermore, the results showed that driving anger facets had positive correlations with dysfunctional ways of expressing anger and negative correlations with the form of the prosocial anger expression. In addition, the results revealed that taxi drivers displayed considerably higher levels of anger while driving and aggressive driving than truck and bus drivers. Overall, this study replicates and extends the accumulated knowledge of previous investigations, suggesting that the original DAS remains a reliable and stable instrument for measuring driving anger in day-to-day driving conditions.

RESUMO

Studies of the influence of emotions on driving behaviour have produced contradictory conclusions. This confusion is related to two factors: emotional arousal and driving tasks. The purpose of this study is to explore the effects of anger and happiness on the driving behaviour of drivers who encounter a pedestrian-crossing event on an unmarked road, which requires strategic and behavioural choices. Thirty-nine drivers completed a simulated driving task to avoid pedestrians under the influence of state emotion. The results showed that anger increased the average driving speed, the minimum speed when encountering a pedestrian, the probability of passing in front of a pedestrian, and the lateral distance to the pedestrian from the right. However, there was no difference between the impacts of happy and neutral moods on driving behaviour. These results suggest that general risky driving behaviour (e.g., speeding) is mainly affected by anger state. Meanwhile avoidance behaviour patterns in pedestrian-crossing tasks, as a driving behaviour related to prosocial attitudes, are also affected by emotional valence. Recommendations and implications for further research on driving anger are discussed.

RESUMO

BACKGROUND: The present study aimed to evaluate the self-regulatory properties of anger on the performance of individuals under various motivational dispositions using an experimental design. METHODS: The participants were 99 university students who participated in response to extra credit. The performance of the participants was evaluated using the Tower of Hanoi task. Their anger was measured using a facial expression recognition system and arousal was assessed using a heart-rate monitoring device. Two motivational dispositions were assessed: performance goals with normative evaluative standards and performance goals with a focus on outcomes. RESULTS: The results indicated that a nonlinear function explained the relationship between anger, arousal, and achievement under different goal conditions. Specifically, the Cusp Catastrophe Model showed that anger levels beyond a critical point were associated with the unpredictability of performance during the normative goal condition, suggesting that anger disturbed the relationship between arousal and achievement. Interestingly, a linear model was relevant for explaining the same relationships during the outcome goal condition. CONCLUSION: Thus, this study concluded that anger plays a more salient role when coupled with the pressures arising from employing interpersonal evaluative standards.

RESUMO

Human visual systems have evolved to extract ecologically relevant information from complex scenery. In some cases, the face in the crowd visual search task demonstrates an anger superiority effect, where anger is allocated preferential attention. Across three studies (N = 419), we tested whether facial hair guides attention in visual search and influences the speed of detecting angry and happy facial expressions in large arrays of faces. In Study 1, participants were faster to search through clean-shaven crowds and detect bearded targets than to search through bearded crowds and detect clean-shaven targets. In Study 2, targets were angry and happy faces presented in neutral backgrounds. Facial hair of the target faces was also manipulated. An anger superiority effect emerged that was augmented by the presence of facial hair, which was due to the slower detection of happiness on bearded faces. In Study 3, targets were happy and angry faces presented in either bearded or clean-shaven backgrounds. Facial hair of the background faces was also systematically manipulated. A significant anger superiority effect was revealed, although this was not moderated by the target's facial hair. Rather, the anger superiority effect was larger in clean-shaven than bearded face backgrounds. Together, results suggest that facial hair does influence detection of emotional expressions in visual search, however, rather than facilitating an anger superiority effect as a potential threat detection system, facial hair may reduce detection of happy faces within the face in the crowd paradigm.

RESUMO

The Emognition dataset is dedicated to testing methods for emotion recognition (ER) from physiological responses and facial expressions. We collected data from 43 participants who watched short film clips eliciting nine discrete emotions: amusement, awe, enthusiasm, liking, surprise, anger, disgust, fear, and sadness. Three wearables were used to record physiological data: EEG, BVP (2x), HR, EDA, SKT, ACC (3x), and GYRO (2x); in parallel with the upper-body videos. After each film clip, participants completed two types of self-reports: (1) related to nine discrete emotions and (2) three affective dimensions: valence, arousal, and motivation. The obtained data facilitates various ER approaches, e.g., multimodal ER, EEG- vs. cardiovascular-based ER, discrete to dimensional representation transitions. The technical validation indicated that watching film clips elicited the targeted emotions. It also supported signals' high quality.

RESUMO

BACKGROUND AND OBJECTIVES: Facial expression recognition has been studied extensively, including in relation to social anxiety. Nonetheless, a limited number of studies examined recognition of disgust expressions. Results suggest that disgust is perceived as more threatening than anger, and thus may invite more extreme responses. However, few studies have examined responses to facial expressions. These studies have focused on approach-avoidance responses. Our primary aim was to examine to what extent anger and disgust expressions might invite interpersonal responses in terms of quarrelsomeness-agreeableness and dominance-submissiveness. As social anxiety has been previously associated with a heightened sensitivity to anger and disgust expressions, as well as with alterations in quarrelsomeness-agreeableness and dominance-submissiveness, our secondary aim was to examine whether social anxiety would moderate these responses. METHODS: Participants were 55 women and 43 men who completed social anxiety measures, including the Brief Fear of Negative Evaluation scale, and two tasks that involved "targets" expressing anger, disgust, or happiness at 0%, 50%, or 100%. Participants first indicated how quarrelsome or agreeable and how dominant or submissive they would be towards each target, and then how much they would avoid or approach each target. RESULTS: While 100% disgust and anger expressions invited similar levels of quarrelsomeness and avoidance, 50% disgust invited more quarrelsomeness and stronger avoidance than 50% anger. While these patterns were not meaningfully moderated by social anxiety, individuals with higher BFNE scores showed a relatively strong approach of happy faces. LIMITATIONS: Actual interpersonal behaviour in response to facial expressions was not assessed. CONCLUSIONS: Findings support the relevance of disgust as an interpersonal signal and suggest that, especially at mild intensity, disgust may have a stronger impact than anger on people's quarrelsomeness and avoidance responses. Findings provided no support for the view that people with social anxiety would be particularly responsive to disgust (or anger) expressions.

RESUMO

Alzheimer's disease (AD) studies in cognitively normal (CN) older adults age≥65 suggest depression is associated with molecular biomarkers (imaging and cerebrospinal fluid [CSF]). This study used linear mixed models (covariance pattern model) to assess whether baseline CSF biomarkers (Aß42/Aß40, t-Tau/Aß42, p-Tau/Aß42) predicted changes in non-depressed mood states in CN older adults (N = 248), with an average of three follow-up years. Participants with higher levels of CSF biomarkers developed more anger, anxiety, and fatigue over time compared to those with more normal levels. Non-depressed mood states in preclinical AD may be a prodrome for neuropsychiatric symptoms in symptomatic AD.

RESUMO

There is tentative evidence that infants can learn preferences through evaluative conditioning to socioemotional stimuli. However, the early development of evaluative conditioning and the factors that may explain infants' capacity to learn through evaluative conditioning are not well understood. Infants (N = 319; 50.2% boys) participated in a longitudinal study where an evaluative conditioning paradigm using socioemotional stimuli was conducted on two occasions (when infants were 7 and 14 months old, on average). We tested whether repeatedly pairing neutral stimuli (triangular and square shapes) with affective stimuli (angry and happy faces) affects infants' preferences for these shapes. At both timepoints, the majority of infants did not choose the shape that was paired with happy faces, indicating that, in general, learning through evaluative conditioning was not present. However, as expected, individual differences were evident such that infants who spent more time fixating on faces compared to shapes (face-preferrers) during the conditioning trials were significantly more likely than non-face-preferrers to choose the shape paired with happy faces, and this effect strengthened with increasing age.

RESUMO

This study investigated whether androstadienone (AND) influences women's emotional perception of potential mates and rivals in a manner that promotes women's reproductive success. Sixty participants (29 in the fertile phase and 31 in the luteal phase) rated their perception of happiness, sadness, anger and sexual arousal from male and female neutral faces during exposure to AND or control solution on two consecutive days. The results showed that AND led women to perceive neutral female faces as unhappier, regardless of their menstrual cycle phase. In addition, AND led women in the fertile phase (i.e., periovulatory phase) to perceive more anger from neutral female faces. Further, no AND-effects were found on the emotional perception of male faces, nor were there perceptions of the sadness or sexual arousal in female faces. These findings may suggest that AND influences women's cognitive processing that can benefit women from staying away from potential threats or preparing to reduce the costs of intrasexual competition.

RESUMO

Although the brain is known to process threatening emotional stimuli and looming motion rapidly, little is known about how the emotion and motion interact. To address this question, two experiments were carried out which presented angry and neutral emotional faces on a depth-cued background that induced the perception of distance, or a non-cued background. Furthermore, faces either expanded or contracted in size such that they appeared to approach or recede from the viewer. EEG/ERP measures were used to identify the time course of brain activity for these looming and receding, angry and neutral emotional faces. The results of both experiments revealed that the P1 was enhanced by looming angry faces on the depth-cued background, compared to neutral approaching faces, as well as all receding faces, indicating an early interaction of emotion and motion within 100 ms of presentation. Angry expressions were also found to enhance the N170 regardless of movement. These findings suggest that processing of threat and looming motion interact at the very early stages of visual processing. Furthermore, as the modulating effect of looming motion on angry expressions only arose on the depth-cued background, the findings highlight the importance of approaching movements rather than sole increases in the retinal size of the stimuli.

RESUMO

Sex has a significant impact on the perception of emotional expressions. However, it remains unclear whether sex influences the perception of emotions in artificial faces, which are becoming popular in emotion research. We used an emotion recognition task with FaceGen faces portraying six basic emotions aiming to investigate the effect of sex and emotion on behavioural and electrophysiological parameters. 71 participants performed the task while EEG was recorded. The recognition of sadness was the poorest, however, females recognized sadness better than males. ERP results indicated that fear, disgust, and anger evoked higher amplitudes of late positive potential over the left parietal region compared to neutral expression. Females demonstrated higher values of global field power as compared to males. The interaction between sex and emotion on ERPs was not significant. The results of our study may be valuable for future therapies and research, as it emphasizes possibly distinct processing of emotions and potential sex differences in the recognition of emotional expressions in FaceGen faces.
