RESUMO

In this study, it was investigated whether an emotional response would occur in pupil contagion by using skin conductance response (SCR) in 5- and 6-month-old infants. In the experiment, emotional responses to pupil diameter change (dilating/constricting) between the face and eyes regions were compared by using pupil diameter response and SCR. The results showed that pupil diameter responses to pupil diameter changes did not differ between face and eyes regions. The emotional response indicated by the SCR significantly increased when participants looked at dilating pupils of face stimuli compared with when participants looked at constricted pupils of face stimuli. In addition, we found a significant correlation between SCR and pupil dilation in the face. This means that pupil diameter expansion significantly increases emotional response in pupil dilation of the face region.

RESUMO

BACKGROUND: It is known that many surgeons encounter intraoperative adverse events which can result in Second Victim Syndrome (SVS), with significant detriment to their emotional and physical health. There is, however, a paucity of Asian studies in this space. The present study thus aimed to explore the degree to which the experience of an adverse event is common among surgeons in Singapore, as well as its impact, and factors affecting their responses and perceived support systems. METHODS: A self-administered survey was sent to surgeons at four large tertiary hospitals. The 42-item questionnaire used a systematic closed and open approach, to assess: Personal experience with intraoperative adverse events, emotional, psychological and physical impact of these events and perceived support systems. RESULTS: The response rate was 57.5% (n = 196). Most respondents were male (54.8%), between 35 and 44 years old, and holding the senior consultant position. In the past 12 months alone, 68.9% recalled an adverse event. The emotional impact was significant, including sadness (63.1%), guilt (53.1%) and anxiety (45.4%). Speaking to colleagues was the most helpful support source (66.7%) and almost all surgeons did not receive counselling (93.3%), with the majority deeming it unnecessary (72.2%). Notably, 68.1% of the surgeons had positive takeaways, gaining new insight and improving vigilance towards errors. Both gender and surgeon experience did not affect the likelihood of errors and emotional impact, but more experienced surgeons were less likely to have positive takeaways (p = 0.035). Individuals may become advocates for patient safety, while simultaneously championing the cause of psychological support for others. CONCLUSIONS: Intraoperative adverse events are prevalent and its emotional impact is significant, regardless of the surgeon's experience or gender. While colleagues and peer discussions are a pillar of support, healthcare institutions should do more to address the impact and ensuing consequences.

RESUMO

The current study investigated the effectiveness of social robots in facilitating stress management interventions for university students by evaluating their physiological responses. We collected electroencephalogram (EEG) brain activity and Galvanic Skin Responses (GSRs) together with self-reported questionnaires from two groups of students who practiced a deep breathing exercise either with a social robot or a laptop. From GSR signals, we obtained the change in participants' arousal level throughout the intervention, and from the EEG signals, we extracted the change in their emotional valence using the neurometric of Frontal Alpha Asymmetry (FAA). While subjective perceptions of stress and user experience did not differ significantly between the two groups, the physiological signals revealed differences in their emotional responses as evaluated by the arousal-valence model. The Laptop group tended to show a decrease in arousal level which, in some cases, was accompanied by negative valence indicative of boredom or lack of interest. On the other hand, the Robot group displayed two patterns; some demonstrated a decrease in arousal with positive valence indicative of calmness and relaxation, and others showed an increase in arousal together with positive valence interpreted as excitement. These findings provide interesting insights into the impact of social robots as mental well-being coaches on students' emotions particularly in the presence of the novelty effect. Additionally, they provide evidence for the efficacy of physiological signals as an objective and reliable measure of user experience in HRI settings.

RESUMO

Low consumer acceptance of edible insects and insect-based products is one of the main barriers to the successful implementation of entomophagy in Western countries. This rejection is mainly caused by consumers' negative emotional responses, psychological/personality traits, and attitudes toward food choices. However, as the role of intrinsic product characteristics on such food choices has not been adequately studied, a systematic review was conducted following the PRISMA method, to analyze studies that have assessed hedonic evaluations, sensory profiling, or emotional responses to edible insects or insect-based products. The majority of studies performed with whole insects and insect flour highlight that insect-based products are more negatively evaluated than control products. Although the sensory properties of insects are affected by species and processing conditions, they are generally negative across sensory dimensions. In particular, insects and insect-based products are generally associated with odor and flavor/taste attributes that are related to old/spoiled food. These negative attributes can be linked to the fat fraction of edible insects, with insect oils being very negatively evaluated by consumers. On the other hand, defatted fractions and deodorized oils are not associated with these negative attributes, further supporting the hypothesis that the fat fraction is responsible for the negative odor and flavor/taste attributes. However, there is still a lack of studies assessing the sensory profile of edible insects and insect-based products, as well as consumers' emotional responses to their consumption. Future studies should focus on the effects of different processing conditions, products incorporating insect fractions (namely protein concentrates/isolates and defatted fractions), and evaluation by target consumer groups.

RESUMO

Emotional perception and expression are very important for building intelligent conversational systems that are human-like and attractive. Although deep neural approaches have made great progress in the field of conversation generation, there is still a lot of room for research on how to guide systems in generating responses with appropriate emotions. Meanwhile, the problem of systems' tendency to generate high-frequency universal responses remains largely unsolved. To solve this problem, we propose a method to generate diverse emotional responses through selective perturbation. Our model includes a selective word perturbation module and a global emotion control module. The former is used to introduce disturbance factors into the generated responses and enhance their expression diversity. The latter maintains the coherence of the response by limiting the emotional distribution of the response and preventing excessive deviation of emotion and meaning. Experiments are designed on two datasets, and corresponding results show that our model outperforms existing baselines in terms of emotional expression and response diversity.

RESUMO

OBJECTIVE: The aim: The main purpose of this article was to investigate the subjective understanding, interest, and emotional perception of non-verbal stimuli by schizophrenic patients. PATIENTS AND METHODS: Materials and methods: For this study, the clinical interview method was used, in which all questions were presented in Ukrainian. The questionnaire form was divided into three main blocks: socio-demographic, mental anamnesis, and non-verbal stimulus assessment. 50 respondents took part in the study. The experimental group, i.e., respondents with schizophrenia spectrum disorders, made up 58% (n = 29) of the total number of respondents, and the control group, respondents with other diagnoses, made up 42% (n = 21). RESULTS: Results: The results showed that in both groups the level of abstractness or objectivity of the drawings affected the understanding of what was depicted. Patients with schizophrenia had a better understanding of images that didn't have a single semantic and compositional whole. The abstractness of the drawings and their detailing affected the appearance of interest in the image in people who have disorders on the schizophrenia spectrum. In addition, the more realistic the objects in the picture were, the less interesting it was for people with schizophrenia spectrum disorders. CONCLUSION: Conclusions: In conclusion, schizophrenic patients found stereotypical signs of emotions much more easily than respondents with other diagnoses, and facial expressions were the most important factor in determining the emotional component of drawings.

RESUMO

For this study, the authors measured attitudes toward shopping for food and cooking, before and during the first lockdown due to the COVID-19 pandemic, among a sample of 526 Danish consumers, using an online survey. To analyse changes due to the lockdown, they applied a latent class Markov model, which revealed four states: middle of the road, love cooking (and like shopping), like shopping and cooking, and do not like shopping or cooking. In estimating transition probabilities, the findings reveal that most respondents remained in the same state before and during the lockdown, but those that changed were more likely to exhibit relatively higher liking of shopping and cooking. These states also reflect variations in people's food literacy and self-reported food consumption. Finally, respondents with stronger negative emotional reactions to the lockdown were more likely to change their states.

RESUMO

OBJECTIVES: Many older adults experience memory changes that can have a meaningful impact on their everyday lives, such as restrictions to lifestyle activities and negative emotions. Older adults also report a variety of positive coping responses that help them manage these changes. The purpose of this study was to determine how objective cognitive performance and self-reported memory are related to the everyday impact of memory change. METHODS: We examined these associations in a sample of 94 older adults (age 60-89, 52% female) along a cognitive ability continuum from normal cognition to mild cognitive impairment. RESULTS: Correlational analyses revealed that greater restrictions to lifestyle activities (|rs| = .36-.66), more negative emotion associated with memory change (|rs| = .27-.76), and an overall greater burden of memory change on everyday living (|rs| = .28-.61) were associated with poorer objective memory performance and lower self-reported memory ability and satisfaction. Performance on objective measures of executive attention was unrelated to the impact of memory change. Self-reported strategy use was positively related to positive coping with memory change (|r| = .26), but self-reported strategy use was associated with more negative emotions regarding memory change (|r| = .23). CONCLUSIONS: Given the prevalence of memory complaints among older adults, it is important to understand the experience of memory change and its impact on everyday functioning in order to develop services that target the specific needs of this population.

RESUMO

Invasive or uncomfortable procedures especially during healthcare trigger emotions. Technological development of the equipment and systems for monitoring and recording psychophysiological functions enables continuous observation of changes to a situation responding to a situation. The presented study aimed to focus on the analysis of the individual's affective state. The results reflect the excitation expressed by the subjects' statements collected with psychological questionnaires. The research group consisted of 49 participants (22 women and 25 men). The measurement protocol included acquiring the electrodermal activity signal, cardiac signals, and accelerometric signals in three axes. Subjective measurements were acquired for affective state using the JAWS questionnaires, for cognitive skills the DST, and for verbal fluency the VFT. The physiological and psychological data were subjected to statistical analysis and then to a machine learning process using different features selection methods (JMI or PCA). The highest accuracy of the kNN classifier was achieved in combination with the JMI method (81.63%) concerning the division complying with the JAWS test results. The classification sensitivity and specificity were 85.71% and 71.43%.

RESUMO

Adolescents use some types of homophobic language (e.g., "that's so gay") as a form of banter, while other types are directly targeted as an intentional insult (e.g., calling someone a "fag, dyke, homo"). Little research has investigated adolescents' use and judgments about these types of homophobic language and whether judgments differ if they are used among friends or directed toward non-friend peers. This study investigated how relationship context and victim's (N = 477, Mage = 14.7, SD = 1.63) emotional responses related to judgments about anti-gay banter and homophobic name-calling. Adolescents evaluated homophobic name-calling as more wrong than anti-gay banter. While adolescents' evaluations of homophobic name-calling did not differ based on relationship context, adolescents did differentiate between anti-gay banter perpetrated by a friend vs. a peer. Further, emotional responses mediated these relationships in the anti-gay banter situation. These results suggest that adolescents' judgments about homophobic language are related to the relationship context and the type of homophobic language used.

RESUMO

Objectives: In the three experimental conditions we examined the role of the exposure to recorded infant's cry (at high and at lower frequency) or laughter and the level of participants' general self-efficacy on emotional reactions to the infant's cry.Background: Infant's cry can trigger empathic, sensitive responses or elicit frustration and anxiety of the caregiver. General caregiver's self-efficacy serves as a predictor of more sensitive reactions to distress cues of a child.Method: An experimental study with three conditions - exposure to infant cry at high frequency, infant cry at lower frequency or infant laughter, was conducted on the sample of 192 childless undergraduates. Exposure to the selected stimulus was preceded by the General Self-Efficacy Scale and followed by the My Emotions Scale for the assessment of participants' emotional reactions to the presented infant crying or laughter.Results: Participants with high self-efficacy exposed to the child's cry at high frequency presented the highest level of child-oriented emotional reactions and lower level of self-oriented reactions as compared to participants with low self-efficacy.Conclusion: Results suggest that general self-efficacy can serve as a supportive factor in sensitive responding to the high-frequency cry. Improving caregivers' self-efficacy can reduce the risk of insensitive, disturbed parenthood.

RESUMO

BACKGROUND: Individuals' emotional responses to stressors in everyday life are associated with long-term physical and mental health. Among many possible risk factors, the stressor-related emotional responses may play an important role in future development of depressive symptoms. PURPOSE: The current study examined how individuals' positive and negative emotional responses to everyday stressors predicted their subsequent changes in depressive symptoms over 18 months. METHODS: Using an ecological momentary assessment approach, participants (n = 176) reported stressor exposure, positive affect (PA), and negative affect (NA) five times a day for 1 week (n = 5,483 observations) and provided longitudinal reports of depressive symptoms over the subsequent 18 months. A multivariate multilevel latent growth curve model was used to directly link the fluctuations in emotions in response to momentary stressors in everyday life with the long-term trajectory of depressive symptoms. RESULTS: Adults who demonstrated a greater difference in stressor-related PA (i.e., relatively lower PA on stressor vs. nonstressor moments) reported larger increases in depressive symptoms over 18 months. Those with greater NA responses to everyday stressors (i.e., relatively higher NA on stressor vs. nonstressor moments), however, did not exhibit differential long-term changes in depressive symptoms. CONCLUSIONS: Adults showed a pattern consistent with both PA and NA responses to stressors in everyday life, but only the stressor-related changes in PA (but not in NA) predicted the growth of depressive symptoms over time. These findings highlight the important-but often overlooked-role of positive emotional responses to everyday stressors in long-term mental health.

RESUMO

A highly prevalent and relevant situation in which adolescents have to interpret the intentions of others is when they interact with peers. We therefore successfully introduced a new paradigm to measure hostile attribution bias (HAB) and emotional responses to such social interactions and examined how it related to youth's aggressiveness. We presented 881 adolescents (Mage = 14.35 years; SD = 1.23; 48.1% male) with audio fragments of age-mates expressing social comments that varied in content (e.g., what the person says) and tone of voice (e.g., how the person says it). Participants' peers also reported on their aggressiveness. In general, added negativity of content and tone was driving the youth's intent attribution and emotional responses to the comments. In line with the Social Information Processing model, we found more hostile attribution of intent and more negative emotional responses of aggressive youth to ambiguous stimuli. Aggression was also related to more hostile intent attributions when both content and tone were negative. Unlike most studies on HAB, the aggression effects in the current study emerged for girls, but not boys. Implications of these results and future use of the experimental paradigm are discussed.

RESUMO

OBJECTIVES: To investigate emotional responses to food images in women with eating disorders (EDs) and healthy controls (HCs); and in underweight individuals post weight-restoration. METHODS: Women (>14 years) with (n = 139) and without (n = 41) an ED rated food images evoking fear, disgust and happiness on a three-visual-analogue scale. Underweight participants viewed the images at two time-points; pre- and post-weight-restoration. RESULTS: HCs were significantly happier, less fearful/anxious prior to viewing the images compared with EDs. Negative emotional responses when viewing images were significantly greater (p < .001) in EDs compared with HCs; however, groups did not differ in happiness. Emotional responses were not significantly different within the ED groups. At post weight-restoration, individuals were significantly less anxious/disgusted when viewing the images. CONCLUSIONS: The importance of considering emotional responses when discussing food consumption in EDs trans-diagnostically is highlighted. Weight recovery reduces negative food responses, although responses remained high in comparison to HCs.

RESUMO

Background/aim: The emergence of the coronavirus disease 2019 (COVID-19) outbreak has had an enormous emotional impact on some vulnerable groups, such as people living with human immunodeficiency virus (HIV) (PLHIV). This study was planned with the aim of assessing the anxiety levels of PLHIV and the sources of their anxiety. Materials and methods: A web-based questionnaire was sent to PLHIV using the virtual snowball sampling method. The questionnaire included questions about sociodemographic status, information about HIV infection, and the Beck Anxiety Inventory (BAI). Additionally, some opinions of the participants about COVID-19 were asked. Results: A total of 307 respondents, with a median age of 33 years, from 32 different cities, participated in the study. More than half of the respondents reported the belief that COVID-19 was not sufficiently well-known by the medical community and nearly 45% believed that they would have more complications if they contracted COVID-19. One-fourth of the participants had anxiety. Having a preexisting psychiatric disorder, perceiving that they were practicing insufficient preventive measures, not being sure about the presence of any individuals with COVID-19 in their environment, and living with a household member with a chronic disease were found to be the risk factors of PLHIV for having anxiety during this pandemic. The BAI scores were correlated with the patient-reported anxiety levels about the spread of COVID-19 in Turkey, acquiring COVID-19, transmitting COVID-19 to another person, and transmitting HIV to another person. Among the stated conditions, the most common concern was the spread of COVID-19 all over the country, while the least common was transmitting HIV to someone else. Conclusion: The results revealed that a significant proportion of the sample had anxiety, and the findings were essential for developing evidence-based strategies for decreasing the anxiety of PLHIV, especially for those who had risk factors and to provide them with better health care during this pandemic or other pandemic-like crises.

RESUMO

This study aimed at determining, based on independent predictors of taste intensity and emotional response, whether individual personality traits could affect prediction models of overall liking and preference rank toward basic taste solutions. Sixty-seven participants rated taste intensities (TI) of four basic-taste solutions at both low and high concentrations, and of plain water. Emotional responses toward each sample were measured using a self-reported emotion questionnaire (SE), facial expressions (FE), and/or autonomic nervous system responses (ANS). Participants rated overall liking of the samples and ranked their preferences. Based on the results of a hierarchical cluster analysis of five personality traits measured using the Big Five Inventory, participants were classified into two clusters: cluster N (high neuroticism) and cluster E (high extraversion). Results showed that the SE measure for both clusters N and E was better than the TI, FE, and ANS measures in explaining variances of overall liking or preference rank. A measurement of effect size found that using FE and/or taste intensity measures, along with self-reported emotion measure, could enhance model predictability of overall liking or preference rank toward taste samples for cluster N, while the contribution to the prediction model for cluster E was minimal. ANS measures showed little contribution to the prediction model of overall liking for either cluster. In conclusion, this study shows that personality traits, in particular traits of extraversion and neuroticism, affect not only optimum measures of emotional responses, but also modulate predicting overall liking and preference rank toward basic taste solutions.

RESUMO

Patients with pathological health anxiety (PHA) tend to automatically interpret bodily sensations as sign of a severe illness. To elucidate the neural correlates of this cognitive bias, we applied an functional magnetic resonance imaging adaption of a body-symptom implicit association test with symptom words in patients with PHA (n = 32) in comparison to patients with depression (n = 29) and healthy participants (n = 35). On the behavioral level, patients with PHA did not significantly differ from the control groups. However, on the neural-level patients with PHA in comparison to the control groups showed hyperactivation independent of condition in bilateral amygdala, right parietal lobe, and left nucleus accumbens. Moreover, patients with PHA, again in comparison to the control groups, showed hyperactivation in bilateral posterior parietal cortex and left dorsolateral prefrontal cortex during incongruent (i.e., harmless) versus congruent (i.e., dangerous) categorizations of body symptoms. Thus, body-symptom cues seem to trigger hyperactivity in salience and emotion processing brain regions in PHA. In addition, hyperactivity in brain regions involved in cognitive control and conflict resolution during incongruent categorization emphasizes enhanced neural effort to cope with negative implicit associations to body-symptom-related information in PHA. These results suggest increased neural responding in key structures for the processing of both emotional and cognitive aspects of body-symptom information in PHA, reflecting potential neural correlates of a negative somatic symptom interpretation bias.

RESUMO

Media coverage of disasters potentially damages mental health. Moreover, its effects may differ as recipients may have different emotional responses toward media. The present study examined whether social capital, known to be protective against mental problems, influences a recipient's emotional response toward news media broadcasting of natural disasters via newspapers, television and internet in Japan. Three social capital components, social participation, social support and cognitive social capital, were considered in the present study as each component reportedly had different effect on mental health. This nationwide cross-sectional survey was undertaken in 2015 among 1,200 Japanese citizens aged 15 to 79 years who were selected using the multi-stage sampling procedure. Data were collected via the drop-off pick-up method using a printed structured questionnaire. Negative and positive emotions were classified based on recipients' responses against news media. Among 1,190 participants who reported emotions toward news media, 30.9% (368) had experienced any natural disasters, 37.4% (445) belonged to at least one formal or informal organization (social participation), 40.2% (478) had high social support, and 68.8% (819) had high cognitive social capital. High social support was associated with both reduced negative emotional response (OR 0.66, 95% Confidence Interval (CI) 0.47-0.93) and increased positive emotional response (OR 1.48, 95% CI 1.04-2.12) in multivariate analyses, while high cognitive social capital was only associated with increased positive emotional response (OR 1.62, 95% CI 1.11-2.37). These results suggest protective effects of social support and cognitive social capital against news media coverage of natural disasters.

RESUMO

The muscarinic acetylcholine receptor is an important modulator of medial prefrontal cortex (mPFC) functions, such as the working memory required to bridge a trace interval in associative leaning. Aversive and appetitive trace conditioning procedures were used to examine the effects of scopolamine (0.1 and 0.5 mg/kg, i.p.) in male rats. Follow-up experiments tested the effects of microinfusion of 0.15 µg of scopolamine (0.075 µg of in 0.5 µl/side) in infralimbic (IL) versus prelimbic regions of rat mPFC, in appetitive trace and locomotor activity (LMA) procedures. Systemic scopolamine was without effect in an aversive trace conditioning procedure, but impaired appetitive conditioning at a 2 s trace interval. This effect was demonstrated as reduced responding during presentations of the conditioned stimulus (CS) and during the interstimulus interval (ISI). There was no such effect on responding during food (unconditioned stimulus, US) responding or in the intertrial interval (ITI). In contrast, systemic scopolamine dose-relatedly increased LMA. Trace conditioning was similarly impaired at the 2 s trace (shown as reduced responding to the CS and during the ISI, but not during US presentations or in the ITI) after infusion in mPFC, whereas LMA was increased (after infusion in IL only). Therefore, our results point to the importance of cholinergic modulation in mPFC for trace conditioning and show that the observed effects cannot be attributed to reduced activity.SIGNIFICANCE STATEMENT Events are very often separated in time, in which case working memory is necessary to condition their association in "trace conditioning." The present study used conditioning variants motivated aversively with foot shock and appetitively with food. The drug scopolamine was used to block muscarinic acetylcholine receptors involved in working memory. The results show that reduced cholinergic transmission in medial prefrontal cortex (mPFC) impaired appetitive trace conditioning at a 2 s trace interval. However, scopolamine was without effect in the aversive procedure, revealing the importance of procedural differences to the demonstration of the drug effect. The finding that blockade of muscarinic receptors in mPFC impaired trace conditioning shows that these receptors are critical modulators of short-term working memory.

RESUMO

OBJECTIVE: Our long-term goal is to develop a normative feedback intervention to support head and neck cancer patients in forming realistic expectations about how other people in non-social group settings will respond to their appearance. This study aimed to evaluate the relationship between observer ratings of facial disfigurement and observer ratings of emotional response when viewing photographs of faces of head and neck cancer patients. METHODS: Seventy-five (75) observers rated their emotional response to each of 144 facial photographs of head and neck cancer patients using the Self-Assessment-Manikin and rated severity of facial disfigurement on a 9-point scale. Body image investment of the observers was measured using the Appearance Schemas Inventory-Revised. A standardized multiple regression model was used to assess the relationship between observer ratings of facial disfigurement and observer ratings of emotional response, taking into consideration the age and sex of the patient depicted in the stimulus photograph, as well as the age, sex, and body image investment of the observer. RESULTS: Observers who had a strong emotional response to a patient's facial photograph tended to rate the patient's facial disfigurement as more severe (standardized regression coefficient ß = 0.328, P < 0.001). Sex and age of the observer had more influence on the rating of facial disfigurement than did the patient's demographic characteristics. Observers more invested in their own body image tended to rate the facial disfigurement as more severe. CONCLUSIONS: This study lays the groundwork for a normative database of emotional response to facial disfigurement.
