RESUMO

Individuals with social anxiety often exhibit atypical processing of facial expressions. Previous research in social anxiety has primarily emphasized cognitive bias associated with face processing and the corresponding abnormalities in cortico-limbic circuitry, yet whether social anxiety influences early perceptual processing of emotional faces remains largely unknown. We used a psychophysical method to investigate the monocular advantage for face perception (i.e., face stimuli are better recognized when presented to the same eye compared to different eyes), an effect that is indicative of early, subcortical processing of face stimuli. We compared the monocular advantage for different emotional expressions (neutral, angry and sad) in three groups (N = 24 per group): individuals clinically diagnosed with social anxiety disorder (SAD), individuals with high social anxiety in subclinical populations (SSA), and a healthy control (HC) group of individuals matched for age and gender. Compared to SSA and HC groups, we found that individuals with SAD exhibited a greater monocular advantage when processing neutral and sad faces. While the magnitudes of monocular advantages were similar across three groups when processing angry faces, individuals with SAD performed better in this condition when the faces were presented to different eye. The former findings suggest that social anxiety leads to an enhanced role of subcortical structures in processing nonthreatening expressions. The latter findings, on the other hand, likely reflect an enhanced cortical processing of threatening expressions in SAD group. These distinct patterns of monocular advantage indicate that social anxiety altered representation of emotional faces at various stages of information processing, starting at an early stage of the visual system.

RESUMO

Guilt is a negative emotion elicited by realizing one has caused actual or perceived harm to another person. One of guilt's primary functions is to signal that one is aware of the harm that was caused and regrets it, an indication that the harm will not be repeated. Verbal expressions of guilt are often deemed insufficient by observers when not accompanied by nonverbal signals such as facial expression, gesture, posture, or gaze. Some research has investigated isolated nonverbal expressions in guilt, however none to date has explored multiple nonverbal channels simultaneously. This study explored facial expression, gesture, posture, and gaze during the real-time experience of guilt when response demands are minimal. Healthy adults completed a novel task involving watching videos designed to elicit guilt, as well as comparison emotions. During the video task, participants were continuously recorded to capture nonverbal behaviour, which was then analyzed via automated facial expression software. We found that while feeling guilt, individuals engaged less in several nonverbal behaviours than they did while experiencing the comparison emotions. This may reflect the highly social aspect of guilt, suggesting that an audience is required to prompt a guilt display, or may suggest that guilt does not have clear nonverbal correlates.

RESUMO

BACKGROUND: Healthcare staff deliver patient care in emotionally charged settings and experience a wide range of emotions as part of their work. These emotions and emotional contexts can impact the quality and safety of care. Despite the growing acknowledgement of the important role of emotion, we know very little about what triggers emotion within healthcare environments or the impact this has on patient safety. OBJECTIVE: To systematically review studies to explore the workplace triggers of emotions within the healthcare environment, the emotions experienced in response to these triggers, and the impact of triggers and emotions on patient safety. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, four electronic databases were searched (MEDLINE, PsychInfo, Scopus, and CINAHL) to identify relevant literature. Studies were then selected and data synthesized in two stages. A quality assessment of the included studies at stage 2 was undertaken. RESULTS: In stage 1, 90 studies were included from which seven categories of triggers of emotions in the healthcare work environment were identified, namely: patient and family factors, patient safety events and their repercussions, workplace toxicity, traumatic events, work overload, team working and lack of supervisory support. Specific emotions experienced in response to these triggers (e.g., frustration, guilt, anxiety) were then categorised into four types: immediate, feeling states, reflective, and longer-term emotional sequelae. In stage 2, 13 studies that explored the impact of triggers or emotions on patient safety processes/outcomes were included. CONCLUSION: The various triggers of emotion and the types of emotion experienced that have been identified in this review can be used as a framework for further work examining the role of emotion in patient safety. The findings from this review suggest that certain types of emotions (including fear, anger, and guilt) were more frequently experienced in response to particular categories of triggers and that healthcare staff's experiences of negative emotions can have negative effects on patient care, and ultimately, patient safety. This provides a basis for developing and tailoring strategies, interventions, and support mechanisms for dealing with and regulating emotions in the healthcare work environment.

RESUMO

BACKGROUND: In recent years, the use of artificial intelligence (AI) in education has increased worldwide. The launch of the ChatGPT-3 posed great challenges for higher education, given its popularity among university students. The present study aimed to analyze the attitudes of university students toward the use of ChatGPTs in their academic activities. METHOD: This study was oriented toward a quantitative approach and had a nonexperimental design. An online survey was administered to the 499 participants. RESULTS: The findings of this study revealed a significant association between various factors and attitudes toward the use of the ChatGPT. The higher beta coefficients for responsible use (ß=0.806***), the intention to use frequently (ß=0.509***), and acceptance (ß=0.441***) suggested that these are the strongest predictors of a positive attitude toward ChatGPT. The presence of positive emotions (ß=0.418***) also plays a significant role. Conversely, risk (ß=-0.104**) and boredom (ß=-0.145**) demonstrate a negative yet less decisive influence. These results provide an enhanced understanding of how students perceive and utilize ChatGPTs, supporting a unified theory of user behavior in educational technology contexts. CONCLUSION: Ease of use, intention to use frequently, acceptance, and intention to verify information influenced the behavioral intention to use ChatGPT responsibly. On the one hand, this study provides suggestions for HEIs to improve their educational curricula to take advantage of the potential benefits of AI and contribute to AI literacy.

RESUMO

Eating decisions may be influenced by an impact bias, or the tendency to overestimate the intensity and duration of emotions for future events or outcomes. In this study, we tested the impact bias, among college students, for eating a novel health food - kale chips. We also examined how an emotion adaptation recall exercise influenced emotions and eating behavior. After reading about the health benefits of kale, college students (N = 80) reported their anticipated emotions (e.g., how intensely they would experience each emotion) for eating kale chips. Following a control (n = 40) or emotion adaptation (n = 40) writing exercise, they were asked to eat these chips. They then reported their experienced emotions (e.g., how intensely they experienced each emotion) as well as their intentions to eat kale in the future. Findings indicated that participants showed a negative impact bias in which they anticipated more intense negative emotions than they experienced. However, they showed an opposite effect for positive emotions, anticipating lower positive emotion than they experienced. Relative to the control group, those who did an emotion adaptation exercise experienced lower levels of disgust after eating kale chips and reported higher intentions to eat them in the future. Subsequent analyses of consumption revealed that those in the emotion adaptation condition also ate more of the kale chips. Findings suggest that affective forecasting theory may be a useful framework through which to develop and test ideas about emotions and eating in the context of novel health foods.

RESUMO

Dogs (Canis lupus familiaris) are the domestically bred descendant of wolves (Canis lupus). However, selective breeding has profoundly altered facial morphologies of dogs compared to their wolf ancestors. We demonstrate that these morphological differences limit the abilities of dogs to successfully produce the same affective facial expressions as wolves. We decoded facial movements of captive wolves during social interactions involving nine separate affective states. We used linear discriminant analyses to predict affective states based on combinations of facial movements. The resulting confusion matrix demonstrates that specific combinations of facial movements predict nine distinct affective states in wolves; the first assessment of this many affective facial expressions in wolves. However, comparative analyses with kennelled rescue dogs revealed reduced ability to predict affective states. Critically, there was a very low predictive power for specific affective states, with confusion occurring between negative and positive states, such as Friendly and Fear. We show that the varying facial morphologies of dogs (specifically non-wolf-like morphologies) limit their ability to produce the same range of affective facial expressions as wolves. Confusion among positive and negative states could be detrimental to human-dog interactions, although our analyses also suggest dogs likely use vocalisations to compensate for limitations in facial communication.

RESUMO

Despite being of undisputed importance, there is no consensus on what emotions are, with the majority of research that constructs ideas about them being colored by a particular worldview. This conceptual article examines the case for conducting an Islamic analysis of emotion. It might seem a peculiar area to examine; what would be the need to analyze such a universal psychological concept through the lens of a particular religion? Three points are used to argue for this endeavor. To begin with, this article highlights the relative instability of the term; there is yet no universally agreed upon definition of what emotions are, and which human processes they contribute to. As the concept is still being defined, there is merit in engaging with the discussion, particularly given the relative absence of metaphysics from the debate. Secondly, specificities relating to emotions and how they have conceptualized are considered. This section delves into the way in which variable factors, such as culture, language, and worldview, influence how emotions manifest. The overarching point argued for here is that how emotions are experienced, and even which emotions are experienced, are shaped by factors that are not consistent across time and space. Accordingly, different worldviews will formulate different "emotional palates" and "emotional ideologies"; different groups of people will understand and engage with emotions differently. Thirdly, a broader discussion ensues pertaining to the nature of science, psychology, and their relationship with secularity. This discussion includes critique of the idea that forces such as secularism and scientific materialism have been "discovered" and are therefore value-neutral. Accordingly, understandings of emotions to have emerged from the Academy, and contemporary psychology, are value-laden. This section also looks at the origins of science in order to determine whether it is inherently atheistic or areligious, and therefore antagonistic to a religious worldview. The section also challenges the apparent secularity of psychology and key psychologists. A range of other facets pertaining to how the emotions have been conceptualized, such as their relational core, their interaction with moral faculties, and their enmeshment with what is important to individuals and groups, are also considered.

RESUMO

This research work focuses on evaluating the development of our three-step digitization approach, designed to transform traditional lectures into engaging digital learning experiences. Aimed at offering an easy-to-use solution for educators, this approach addresses the pressing challenges of modern educational environments by enhancing accessibility, engagement, and effectiveness of learning through digital means.Quantitative analysis demonstrated a notable increase in knowledge gain for students engaged with the digital format (t(230) = -2.795, p = 0.006) over traditional methods. Additionally, it was observed that the online setting significantly improved concentration levels (t(230) = -5.801, p < .001) and reduced distractions (t(230) = 2.848, p = 0.005). Emotional assessments, based on the Achievement Emotions Questionnaire (AEQ), indicated an elevation in enjoyment (t(230) = -4.717, p < .001) and a reduction in anxiety (t(230) = 9.446, p < .001) within the digital learning environment. A substantial preference for the digital course format was expressed by 61.0% of participants, with 71.4% acknowledging its superior efficiency compared to 14.3% for traditional lectures.Qualitative feedback underscored the digital format's flexibility, comprehensive learning experience, and immediate feedback as key benefits. Nevertheless, nuances such as a preferred understanding in face-to-face interactions and the absence of a social component in digital settings were noted.To conclude, the findings from this study illuminate the significant advantages of the three-step digitization approach in meeting contemporary educational challenges. By facilitating an enhanced knowledge acquisition and fostering a supportive emotional climate, this approach signifies a promising direction for the future of medical education and beyond, fusing the convenience of digital solutions with the depth and engagement of traditional learning methodologies.

RESUMO

Technological breakthroughs such as artificial intelligence and sensors make human-robot collaboration a reality. Robots with highly reliable, specialised skills gain informal status in collaborative teams, but factors such as unstructured work environments and task requirements make robot error inevitable. So how do status differences of errant robots affect the desire for contact, and do team characteristics also have an impact? This paper describes an intergroup experiment using the Experimental Vignette Method (EVM), based on the Expectation Violation Theory, 214 subjects were invited to test the following hypotheses: (1) Errant robot status has an influence on employees' desire for contact and support for robotics research through negative emotions; (2) Team interdependence is a boundary condition for the effect of errant robot status on negative emotions. This paper contributes to the literature on employee reactions to robot errors in human-robot collaboration and provides suggestions for robot status design.


Complex human-robot collaboration inevitably leads to the phenomenon of robot errors. Based on this, we used an Experimental Vignette Method and found that differences in robot status design and human-robot team design features significantly affect employees' cognitive psychology after robot errors and reduce the negative consequences.

RESUMO

PURPOSE: The concept of Entrustable Professional Activities (EPA) is increasingly used to operationalize learning in the clinical workplace, yet little is known about the emotions of learners feeling the responsibility when carrying out professional tasks. METHODS: We explored the emotional experiences of medical students in their final clerkship year when performing clinical tasks. We used an online reflective diary. Text entries were analysed using inductive-deductive content analysis with reference to the EPA framework and the control-value theory of achievement emotions. RESULTS: Students described a wide range of emotions related to carrying out various clinical tasks. They reported positive-activating emotions, ranging from enjoyment to relaxation, and negative-deactivating emotions, ranging from anxiety to boredom. Emotions varied across individual students and were related to the characteristics of a task, an increasing level of autonomy, the students' perceived ability to perform a task and the level of supervision provided. DISCUSSION: Emotions are widely present and impact on the workplace learning of medical students which is related to key elements of the EPA framework. Supervisors play a key role in eliciting positive-activating emotions and the motivation to learn by providing a level of supervision and guidance appropriate to the students' perceived ability to perform the task.

RESUMO

Although chocolates are often chosen for sensory pleasure, they are also selected to enhance mood and relieve emotional stress, or potentially chosen for its perceived health benefits if stress adversely affects physical well-being. This study aimed to investigate whether emotional stress influenced the motivations behind chocolate selection, subsequent liking, and emotional response. Participants were divided into a control group (n = 76) and a group with induced acute stress (n = 74). Stimuli were presented as dark chocolate packaging, each evoking sensory appeal, health, and emotional stress relief. Participants chose one stimulus from three options that they were most inclined to consume and evaluated the overall liking and emotional attributes of the stimuli. They also rated the overall liking and emotional attributes of three types of chocolates, each identical but paired with distinct stimuli. Their food attitudes were also assessed. Stress did not change the choice of stimuli, indicating that stress did not influence the motivation for chocolate selection. Instead, the choice of stimuli aligned with participants' food attitudes; those favoring sensory appeal and emotional stress relief prioritized pleasure in their usual food choices. Stress tended to increase liking and chocolate-associated positive emotions with sensory appeal, as opposed to others, to immediately alleviate negative emotions. The most robust motivation to consume chocolates was sensory pleasure, irrespective of stress, because of a preestablished association between sensory pleasure and mood enhancement.

RESUMO

Older adults process emotional speech differently than young adults, relying less on prosody (tone) relative to semantics (words). This study aimed to elucidate the mechanisms underlying these age-related differences via an emotional speech-in-noise test. A sample of 51 young and 47 older adults rated spoken sentences with emotional content on both prosody and semantics, presented on the background of wideband speech-spectrum noise (sensory interference) or on the background of multi-talker babble (sensory/cognitive interference). The presence of wideband noise eliminated age-related differences in semantics but not in prosody when processing emotional speech. Conversely, the presence of babble resulted in the elimination of age-related differences across all measures. The results suggest that both sensory and cognitive-linguistic factors contribute to age-related changes in emotional speech processing. Because real world conditions typically involve noisy background, our results highlight the importance of testing under such conditions.

RESUMO

Promoting healthy snacking is important in addressing malnutrition, overweight and obesity among an ageing population. However, little is known about the factors underlying snacking behaviour in older adults. The present study aimed to explore within- and between-person associations between determinants (i.e. intention, visibility of snacks, social modelling and emotions) and snacking behaviours (i.e. decision to snack, health factor of the snack and portion size) in older adults (60+). Conducting a two-part intensive longitudinal design, data was analysed from 48 healthy older adults consisting of (1) an event-based self-report ecological momentary assessment (EMA) diary every time they had a snack and (2) a time-based EMA questionnaire on their phone 5 times per day. Analysis through generalised linear mixed models indicated that higher intention to snack healthily leads to healthier snacking while higher levels of social modelling and cheerfulness promote unhealthier choices within individuals. At the between-person level, similar results were found for intention and social modelling. Visibility of a snack increased portion size at both a within- and between-person level, while the intention to eat a healthy snack only increased portion size at the between-person level. No associations were found between the decision to snack and all determinants. This is the first study to investigate both within- and between-person associations between time-varying determinants and snacking in older adults. Such information holds the potential for incorporation into just-in-time adaptive interventions, allowing for personalised tailoring, more effective promotion of healthier snacking behaviours and thus, pursuing the challenge of healthy ageing.

RESUMO

Students' academic achievement relies on a variety of pedagogical, affective, and individual factors. The investigation of academic emotions and epistemic cognition has been a focal point in existing research. Previous studies have predominantly delved into the essence of students' epistemic cognition and academic emotions. Nonetheless, the correlation between the epistemic cognition, academic emotions, and academic success of Chinese undergraduate students remains inadequately explored. This research delves into the interconnectedness of these variables and examines which facets of epistemic cognition and academic emotions can forecast students' academic performance. A total of three hundred and eighty (380) Chinese undergraduate students were chosen via random sampling for this study. Their self-reported academic achievements were taken into account. Additionally, they completed questionnaires tailored to evaluate their epistemic cognition and academic emotions. The participants' scores underwent Pearson correlation and multiple regression analyses. The findings indicate that positive emotions correlate positively, while negative emotions correlate negatively with students' academic success. Furthermore, positive emotions and three categories of epistemic cognition were found to be predictors of students' academic accomplishments. In conclusion, it is deduced that both epistemic cognition and positive emotions play a role in enhancing students' academic success. The implications of these findings extend to educational psychologists, educators, and students, both theoretically and practically.

RESUMO

In this study, we examined the effects of female coaches' nonverbal pride and shame expressions on female field hockey players' emotions and performance and considered the role of two potential moderating factors. Across two experiments, a between (emotional expression manipulation) within (pre- and post-manipulation) subjects design was employed. A female hockey coach was scripted to deliver performance feedback randomly displaying pride or shame to skilled players (Experiment 1, n = 38; Experiment 2, n = 44) after they had performed a passing test. Players then performed the passing test for a second time. In both experiments, players reported their emotions, perceptions of the coach, and connection with the coach. In Experiment 2, players also rated their emotion regulation ability. The results showed that displayed pride elicited pride in players while displayed shame elicited shame in players. Further, coaches' pride and shame expressions had differential effects on players' performance. Displayed pride consistently improved players' performance. Displayed shame mainly worsened performance, but players' ability to regulate their own emotions seemed to buffer these negative effects. There was further evidence that players' emotions could underpin the performance effects, particularly when players knew the coach. These findings advance the literature by providing further experimental evidence for when and how coaches' pride and shame expressions influence players' emotions and performance and have important practical implications for coaches aiming to optimize performance.

RESUMO

OBJECTIVE: The objective of this study is to conduct a systematic review regarding the relationship between positive psychological factors, such as psychological well-being and pleasant emotions, and sports performance. METHOD: This study, carried out through a systematic review using PRISMA guidelines considering the Web of Science, PsycINFO, PubMed and SPORT Discus databases, seeks to highlight the relationship between other more 'positive' factors, such as well-being, positive emotions and sports performance. SETTINGS: The keywords will be decided by a Delphi Method in two rounds with sport psychology experts. PARTICIPANTS: There are no participants in the present research. ASSESSMENT: The main exclusion criteria were: Non-sport thema, sample younger or older than 20-65 years old, qualitative or other methodology studies, COVID-related, journals not exclusively about Psychology. MAIN OUTCOMES MEASURES: We obtained a first sample of 238 papers, and finally, this sample was reduced to the final sample of 11 papers. RESULTS: The results obtained are intended to be a representation of the 'bright side' of sports practice, and as a complement or mediator of the negative variables that have an impact on athletes' and coaches' performance. CONCLUSIONS: Clear recognition that acting on intrinsic motivation continues to be the best and most effective way to motivate oneself to obtain the highest levels of performance, a good perception of competence and a source of personal satisfaction.

RESUMO

INTRODUCTION: Emotion regulation (ER) develops during adolescence and contributes to psychosocial adjustment. Individual differences in the development of ER strategies may be related to cognitive processes responsible for managing goal-directed behaviors, namely executive functions (EFs). This study examined (1) examined how difficulties in specific EFs (i.e., inhibition, flexibility and working memory) predict the use of ER strategies (i.e., reappraisal, distraction, expressive suppression, rumination, support-seeking) in an emotion-specific approach and (2) investigated these links across three different age groups (corresponding to early, middle and late adolescence), considering the nonlinear evolution of the relationships between EF and ER strategies during adolescence. METHODS: The sample was composed of 1076 adolescents aged from 12 to 19 years old who completed questionnaires on EF difficulties (i.e., inhibition, flexibility, and working memory) and ER strategies (i.e., distraction, reappraisal, expressive suppression, social support-seeking, and rumination). RESULTS: Results showed various complex relationships between EFs and ER. Flexibility issues were related to rumination at all ages, while inhibition and flexibility difficulties were negatively linked to reappraisal in mid- to late adolescence. Many relationships were emotion- and age-dependent. CONCLUSIONS: These findings support the link between cognitive and emotional regulatory processes. Its complex evolution during adolescence opens a new avenue for future research.

RESUMO

Dairy calves are typically fed restricted amounts of milk. Although feed restrictions are predicted to result in negative affective states, the relative aversiveness of 'hunger' remains largely unexplored in this species. Here, we investigated whether the conditioned place preference paradigm can be used to explore how calves feel when experiencing different levels of satiation. This paradigm provides insight into what animals remember from past experiences, the assumption being that individuals will prefer places associated with more pleasant or less unpleasant experiences. Sixteen Holstein calves were either fed a restricted (3 L per meal totalling 6 L per day) or 'enhanced' milk allowance (ad libitum up to 6 L per meal totalling up to 12 L per day) in their home-pen. Calves were then placed in a conditioning pen for 4 h immediately after being fed their morning meal to allow them to develop an association between the pen and their state of post-prandial satiation. Calves were conditioned across four days with their satiation state alternating between days to allow them to develop an association between pen and satiation levels. On the 5th day, calves were individually allowed to roam freely between the two pens for 30 min. We expected that calves would prefer the pen where they previously experienced higher levels of satiation, but our results show no to limited effects of treatment. However, some methodological issues (colour and side bias) prevent us from drawing strong conclusions. We discuss reasons for these issues and potential solutions to avoid these in future studies.

RESUMO

Existing methods for classifying image emotions often overlook the subjective impact emotions evoke in observers, focusing primarily on emotion categories. However, this approach falls short in meeting practical needs as it neglects the nuanced emotional responses captured within an image. This study proposes a novel approach employing the weighted closest neighbor algorithm to predict the discrete distribution of emotion in abstract paintings. Initially, emotional features are extracted from the images and assigned varying K-values. Subsequently, an encoder-decoder architecture is utilized to derive sentiment features from abstract paintings, augmented by a pre-trained model to enhance classification model generalization and convergence speed. By incorporating a blank attention mechanism into the decoder and integrating it with the encoder's output sequence, the semantics of abstract painting images are learned, facilitating precise and sensible emotional understanding. Experimental results demonstrate that the classification algorithm, utilizing the attention mechanism, achieves a higher accuracy of 80.7% compared to current methods. This innovative approach successfully addresses the intricate challenge of discerning emotions in abstract paintings, underscoring the significance of considering subjective emotional responses in image classification. The integration of advanced techniques such as weighted closest neighbor algorithm and attention mechanisms holds promise for enhancing the comprehension and classification of emotional content in visual art.

RESUMO

BACKGROUND: The aim of this research was to analyze whether the personality factors included in the Big Five model differentially predict the self-regulation and affective states of university students and health. METHODS: A total of 637 students completed validated self-report questionnaires. Using an ex post facto design, we conducted linear regression and structural prediction analyses. RESULTS: The findings showed that model factors were differential predictors of both self-regulation and affective states. Self-regulation and affective states, in turn, jointly predict emotional performance while learning and even student health. These results allow us to understand, through a holistic predictive model, the differential predictive relationships of all the factors: conscientiousness and extraversion were predictors regulating positive emotionality and health; the openness to experience factor was non-regulating; nonregulating; and agreeableness and neuroticism were dysregulating, hence precursors of negative emotionality and poorer student health. CONCLUSIONS: These results are important because they allow us to infer implications for guidance and psychological health at university.
