RESUMO
Previous research suggests that emotion recognition is influenced by social categories derived by invariant facial features such as gender and inferences of trustworthiness from facial appearance. The current study sought to replicate and extend these findings by examining the intersection of these social categories on recognition of emotional facial expressions. We used a dynamic emotion recognition task to assess accuracy and response times in the happiness and anger categorization displayed by female and male faces that differed in the degree of facial trustworthiness (i.e., trustworthy- vs. untrustworthy-looking faces). We found that facial trustworthiness was able to modulate the own-gender bias on emotion recognition, as responses to untrustworthy-looking faces revealed a bias towards ingroup members. Conversely, when faces look trustworthy, no differences on emotion recognition between female and male faces were found. In addition, positive inferences of trustworthiness lead to faster recognition of happiness in females and anger in males, showing that facial appearance was able to influence also the intersection between social categories and specific emotional expressions. Together, these results suggest that facial appearance, probably due to the activation of approach or avoidance motivational systems, is able to modulate the own-gender bias on emotion recognition.

INTRODUCTION: Several studies have called for attention to medical students' well-being. Building on the neuroevolutionary affective neuroscience perspective that views primary emotional systems as central to well-being and the foundation of personality, this study investigated the facets of medical students' psychological well-being that are challenged and the relationships between emotional traits, psychological well-being, and depression. METHODS: In a single-center cross-sectional study, medical students' primary emotional traits (SEEKING, FEAR, ANGER, SADNESS, CARE, PLAY and Spirituality), psychological well-being dimensions (autonomy, environmental mastery, positive relations, self-acceptance, purpose in life, and personal growth), and depressive symptoms were assessed using the Affective Neuroscience Personality Scale; the Psychological Well-being Scale, which provides normative data; and the Beck Depression Inventory. RESULTS: Compared with the normative data, the medical students perceived lower psychological autonomy, positive relations, and self-acceptance but higher purpose in life. The medical students' emotional traits were related to specific psychological well-being facets and depression. SEEKING and, inversely, FEAR were related to well-being across dimensions and depressive symptoms. CONCLUSION: Our findings are the first to show a link between emotional traits and specific facets of psychological health in medical students. Thus, this study encourages medical teachers to set learning environments that target multiple facets of well-being that harness primary emotional traits.

Personality neuroscience is focusing on the correlation between individual differences and the efficiency of large-scale networks from the perspective of the brain as an interconnected network. A suitable technique to explore this relationship is the magnetoencephalography (MEG), but not many MEG studies are aimed at investigating topological properties correlated to personality traits. By using MEG, the present study aims to evaluate how individual differences described in Cloninger's psychobiological model are correlated with specific cerebral structures. Fifty healthy individuals (20 males, 30 females, mean age: 27.4 ± 4.8 years) underwent Temperament and Character Inventory examination and MEG recording during a resting state condition. High harm avoidance scores were associated with a reduced centrality of the left caudate nucleus and this negative correlation was maintained in females when we analyzed gender differences. Our data suggest that the caudate nucleus plays a key role in adaptive behavior and could be a critical node in insular salience network. The clear difference between males and females allows us to suggest that topological organization correlated to personality is highly dependent on gender. Our findings provide new insights to evaluate the mutual influences of topological and functional connectivity in neural communication efficiency and disruption as biomarkers of psychopathological traits.

Trait inferences based solely on facial appearance affect many social decisions. Here we tested whether the effects of such inferences extend to the perception of physical sensations. In an actual clinical setting, we show that healthcare providers' facial appearance is a strong predictor of pain experienced by patients during a medical procedure. The effect was specific to familiarity: facial features of healthcare providers that convey feelings of familiarity were associated with a decrease in patients' perception of pain. In addition, caring appearance of the healthcare providers was significantly related to patients' satisfaction with the care they received. Besides indicating that rapid, unreflective trait inferences from facial appearance may affect important healthcare outcomes, these findings contribute to the understanding of the mechanisms underlying social modulation of pain perception.

Medical students' motivations for choosing a medical career are likely based on and remain tethered to the affectively-laden caring component of doctor-patient interactions. However, this component is rarely presented in educational surgical videos. It is unknown whether affectively engaging students by including patient-related emotionally salient information potentiates or draws focus away from learning a surgical procedure and whether such information affects motivation and attitudes toward the video. Therefore, we investigate whether presenting a patient's emotional state before video surgery enhances or weakens the educational value of that video. In a within-subjects crossover design, second-year medical students (n = 130) viewed video clips of surgeries. These videos, from online medical education platforms, were preceded by the patient's information from the original video or by information about the patient's preoperative emotional preparation. After each video, participants completed a multiple-choice test about the video's content to measure learning, answered a question about their motivation to re-watch the video, and completed an attitude scale regarding the video. Incorporating patient's information into surgical videos significantly enhanced students' acquisition of the technical aspects of surgery procedures (p < 0.0001), motivation to re-watch the video (p < 0.001), and favorable attitudes toward the video (p = 0.02). These findings show that incorporating information about patients' emotional states may enhance students' positive attitudes and motivations toward educational videos and may improve their learning of surgical techniques. They also suggest that the role of this factor should be considered when developing guidelines for medical educational video release.

Several studies have highlighted the role of heart rate variability (HRV) in social engagement and social cognition. However, whether HRV is involved in the ability to remember faces associated with affectively salient behavioural information remains unexplored. The present study aims to close this gap by investigating long-term face-memory accuracy in individuals differing in resting vagally-mediated HRV. Individuals with high or low resting HRV viewed faces associated with episodic information differing in affective valence (positive, neutral, negative) or without any behavioural description. After one week, a face recognition test was administered. High HRV individuals were better at recognizing faces paired with positive and negative behavioural descriptions compared to neutral faces or faces without descriptions. Conversely, low HRV participants did not show any face memory advantage from personal information. The present results suggest that HRV may provide a novel biological marker of long-term face recognition.

CONTEXT: Identifying the factors that may interfere with or sharpen the ability to recognise emotions when observing patients is a critical goal in medical education. This study addressed these issues by investigating the effects of facial appearance bias on medical students' emotion recognition (Experiment 1) and whether such bias is modulated by the activation of relational caregiving schema (Experiment 2). METHODS: In Experiment 1, medical students were asked to recognise the emotions expressed by individuals differing in facial appearance (trustworthy, neutral and untrustworthy). In Experiment 2, they completed the same type of emotion recognition task after activating and anchoring themselves to the representation of the relational/human competences typical of a competent professional caregiver or after a control non-representation condition. RESULTS: In both experiments, emotion recognition was affected by facial appearance bias: medical students were less accurate and slower in their recognition of emotions displayed by untrustworthy-looking individuals than in their recognition of emotions exhibited by individuals evoking more positive inferences. In Experiment 2, the activation of care schema enhanced medical students' emotion recognition ability regardless of facial appearance-based inferences. CONCLUSIONS: Medical students' emotion recognition is affected by appearance-based bias, but such bias may be weakened by techniques that harness medical students' personal affective/relational and representational resources. Thus, the results provide a basis for designing curricula aimed at challenging implicit negative bias and promoting medical students' emotion recognition ability starting in the early stages of their education.

We tested whether episodic information about people facilitates memory for their faces (Experiment 1) and whether this effect is specific for face identity (Experiment 2). Participants were presented with faces paired with behavioral descriptions (positive, neutral, or negative) and faces displayed alone. In both experiments, participants were more likely to recognize faces paired with behavioral descriptions, and after 1-week delay, their memory was better for faces paired with descriptions of salient behavior (i.e., with positive and negative valence) than faces paired with neutral behaviors or faces presented without information. To examine whether these effects are about memory for face identity rather than face image memory, in Experiment 2, we presented different facial images (varying in facial angle) of the same people at the encoding and at the recognition test. Although this manipulation decreased the overall recognition, the findings of Experiment 1 were fully replicated. The findings suggest that minimal affective information is sufficient to facilitate memory for face identity.

We investigated whether the bodily-mediated production of verbs emerges earlier than verb recognition and oral production during early language acquisition. Children (aged 18-22, 23-27, 28-32, and 33-37 months) viewed animated pictures representing actions related to transitive and intransitive verbs and were asked to (i) orally indicate the verb presented, (ii) recognize the target verb among other verbs, and (iii) perform the actions corresponding to the target verb enunciated by the experimenter. Children 18-22 months showed a capacity to enact the verbs, while their recognition and oral production abilities were not comparably developed. Until 27 months of age, children produced more transitive than intransitive verbs across tasks. The gap between verb recognition and verb oral production was found in all ages tested. This is the first study to directly demonstrate that the ability to produce verbs, especially transitive verbs, via overt body actions emerges ontogenetically earlier than recognition and oral production.

Several studies indicate a link between personal distress and vulnerability to depression. The literature also suggests that personal distress is associated with emotion dysregulation and that emotion dysregulation plays a role in depression. However, which of the various emotion regulation difficulties mediates the relationship between personal distress and depression remains unexplored. This study therefore aims to investigate the mediating role of specific emotion regulation difficulties in the relationship between personal distress and depression. Of the 702 initially recruited participants, 635 completed a survey comprising the Interpersonal Reactivity Index, the Difficulties in Emotion Regulation Scale, and the Beck Depression Inventory. A mediation analysis was used to explore which emotion regulation difficulties mediate the relationship between personal distress and depression. Over a quarter (27%) of participants reported moderate-severe depression symptoms. Difficulties in accessing adaptive emotion regulation strategies and in having a clear understanding about one's own emotions partly mediated the relationship between personal distress and depression symptoms. Our results are the first to indicate that personal distress is linked to depression risk through specific emotion regulation difficulties in medical students. They also highlight possible modifiable skills that could be targeted by prevention intervention.
RESUMO
INTRODUCTION: Evaluation of post-nephrectomy social health in living kidney donors is essential. This systematic review examines their emotional need for social relatedness post-donation. METHODS: Following the PRISMA guidelines, we systematically searched Scopus, CINAHL, and PsycINFO. RESULTS: Among the screened records, 32 quantitative and 16 qualitative papers met the inclusion criteria. Quantitative research predominantly utilized questionnaires featuring generic items on social functioning. However, a minority delved into emotional and social dimensions, aligning with qualitative studies emphasizing the importance of social connection and perceived social support post-donation. Specifically, post-donation changes in connecting with others encompass a sense of belongingness, heightened autonomy, shifts in concern for the recipient's health, and continued care by shielding the recipient from personal health issues. Social acknowledgment and social support from both close and extended networks are reported as relevant for recovery after nephrectomy. DISCUSSION: These findings underscore the necessity for targeted measures of emotional needs and social functioning to effectively assess post-donation adjustment. They also inform the identification of key health themes for kidney donor Patient-Reported Outcome Measures (PROMs) and Patient-Reported Experience Measures (PREMs) questions.
RESUMO
OBJECTIVE: Preclinical models of human mood disorders commonly focus on the study of negative affectivity, without comparably stressing the role of positive affects and their ability to promote resilient coping styles. We evaluated the role of background constitutional affect of rats by studying the separation and reunion responses of infants from low and high positive affect genetic lines (i.e., differentially selected for High and Low 50 kHz ultrasonic vocalisations (USVs). METHODS: Infants from Low and High 50 kHz USV breeding lines were isolated from mothers and exposed to either social (familiar or unfamiliar bedding) or neutral (clean bedding) odour cues between two short isolation periods, and tested in homeothermic and hypothermic ambient temperatures. Negative affect was estimated by monitoring separation distress calls (35-45 kHz USVs). RESULTS: Low Line pups called at higher rates than High Line, and their rates were stable regardless of odour cue. In contrast, High Line pups increased vocalisations during the second compared with the first isolation periods and during exposure to both familiar and unfamiliar odour cues, but not to neutral odour. Furthermore, the greatest increase in USV emission was seen in the second isolation period following exposure to the unfamiliar odour. However, both lines showed comparable elevated distress USVs to the thermal stressor. CONCLUSION: High Line animals, selected for a positive affective phenotype (50 kHz USVs), exhibited reduced separation anxiety responses in infancy, making this a promising animal model for the role of constitutional affective states in emotional responsivity and potential resilience against emotional disorders.
RESUMO
Social context has been shown to influence pain perception. This study aimed to broaden this literature by investigating whether relevant social stimuli, such as faces with different levels of intrinsic (based on physical resemblance to known individuals) and episodic (acquired through a previous experience) familiarity, may lead to hypoalgesia. We hypothesized that familiarity, whether intrinsic or acquired through experience, would increase pain threshold and decrease pain intensity. Sixty-seven participants underwent pain induction (the cold pressor test) viewing previously seen faces (Episodic Group) or new faces (Non-episodic Group) that differed in the level of intrinsic familiarity (high vs low). Pain threshold was measured in seconds, while pain intensity was measured on a rating scale of 0 to 10. The results did not show an effect of episodic familiarity. However, compared to low, high intrinsic familiar faces had an attenuating effect on pain intensity, even after controlling for pain expectation. These results suggest that physical features conveying a higher feeling of familiarity induce a top-down hypoalgesic modulation, in line with the idea that familiarity may signal safety and that the presence of familiar others reduce perceived threat-related distress. This study provides further evidence on the social modulation of pain and contributes to the literature on first impressions' influence on social behavior. PERSPECTIVE: Consistent with the idea that familiar others signal safety and reduce the sense of threat, facial features conveying familiarity induce a top-down hypoalgesic modulation. This knowledge may contribute to understanding differences in pain perception in experimental and clinical contexts.

INTRODUCTION: A significant reorganization of working activities including those of teaching hospitals occurred after COVID-19 outbreak, leading to the need to re-assess the current status of training after the pandemic. This study aimed to investigate the state of general surgery (GS) residency in Italy. The impact of COVID-19 on GS residents was also assessed. METHODS: Between October and November 2020, an anonymous online survey was distributed to GS residents across Italy. Email addresses were provided by the Regional Committees of the Italian Polyspecialistic Society of Young Surgeons. The residents completed a set of questions regarding their training schedule and three standardized questionnaires to measure burnout and psychological distress. RESULTS: Overall, 1709 residents were contacted and 648 completed the survey. Almost two-thirds of the residents (68.4%, n = 443) reported to not reach the minimum annual operative case volume. According to ordinal logistic regression analysis, two of the most perceived effects of COVID-19 by trainees on training were reduction of surgical activities (OR = 2.21, p < 0.001) and increased concerns about future employment (OR = 1.14, p = 0.025). Loss of training opportunities was also associated with a significant increase of distress (OR = 1.26, p = 0.003) but not with burnout. CONCLUSIONS: This study provided a snapshot of the situation of GS residents in Italy after COVID-19 outbreak. Reduction of activities due to pandemic highlighted the need to improve the level of surgical education in our country by implementing all the new available tools for training and ensuring at the same time the well-being of the residents.

INTRODUCTION: Several studies report that medical students are at high risk of depression. Despite the variability in students' vulnerability to depression, the role of individual differences in depression risk among medical students has hardly been investigated. Studies outside of medical student populations have shown that individual differences in attachment style and emotion regulation participate in vulnerability to depression. OBJECTIVES: This study investigates to what extent medical students' depressive symptoms are related to differences in students' insecure attachment styles and their perception of reduced access to emotion regulation strategies. METHODS: In a cross-sectional quantitative study, undergraduate medical students at the beginning of their second academic year completed online questionnaires measuring their attachment style, difficulties in emotion regulation, and depressive symptoms. RESULTS: Out of the 390 medical students invited, 267 participated in the survey. Higher secure attachment was associated with fewer depressive symptoms. Medical students' insecure attachment style and emotion dysregulation were significantly related to depressive symptoms. Difficulties in employing strategies to disengage from one's own negative affect partly mediated the effects of two dimensions of insecure anxious attachment-need for approval and preoccupation with relationships-on depressive symptoms. DISCUSSION: Anxious attachment style and limited access to emotion regulation strategies participate in medical students' depressive symptoms. These findings highlight the need for acknowledging medical students' attachment style and students' perceived access to emotion regulation strategies for the early identification of and intervention programs for the risk of depression.

Octodon degus is a social caviomorph species that exhibits strong social bonds and robust distress responses to maternal separation. To understand the impact of early social isolation on social motivation, we investigated how social isolation during infancy, associated with repeated restricted interactions with mother and siblings, altered social motivation in young degus. In Experiment 1, three treatments were compared: complete isolation (ISOLATED group), nearly complete isolation, with daily half hour partition-restricted reunions with the mother and siblings (RESTRICTED group), and social-housing with the mother and siblings (FAMILY group). After 10 days of treatment, all subjects underwent a 5-day choice test between mothers and unfamiliar females. During the treatment period, the RESTRICTED animals emitted more isolation calls and spent more time close to the partition that separated them from mothers than ISOLATED animals. During the first social-choice day, FAMILY reared animals showed a preference for the mother for a few minutes, while the RESTRICTED animals preferred the mother for the whole session. Totally ISOLATED pups exhibited no social preferences. Since during successive testing periods the isolation calls decreased over the days, in Experiment 2 we investigated whether this decline was related to age or habituation to testing procedures. Animals were observed during a single exposure to isolation (ISOLATED) or restricted-reunion (RESTRICTED) at PND 21 and 31. The decrease of vocalizations was due to an age-effect. The findings clarify the nature of social bonds in degus.

We investigated whether positive daily peer-interactions counteract the effects of isolation in Octodon degus. Twenty-five-day-old degus were either isolated (ISO), socially housed (SOCIAL), or isolated and allowed 1-hr daily peer interaction (PARTIAL-ISO). The animals were observed over 4 weeks. Just prior to isolation and after 2 weeks of individual housing, the subjects were assessed for response to pleasant stimuli via a sucrose preference test and to fearful situations in open field and startle tests. Two weeks after the previous tests, the subjects were retested as above and observed in novelty and sociability tests. Only the ISO group showed significant alterations in sensitivity to reward and increased risk-taking behavior in fearful situations. The ISO group consumed more sucrose, spent less time freezing in the startle test and exhibited increased exploration in open field and novelty tests compared to PARTIAL-ISO and SOCIAL groups. In the sociability test, the SOCIAL group vocalized more than the other two groups during encounters with an unfamiliar degus. Our findings suggest that (i) chronic isolation induces alteration of hedonic, emotional and social profiles, with a maturational delay in fear-related responses; (ii) friendly interaction attenuates most behavioral changes induced by total social isolation. However, the positive effects of daily social interactions did not fully counteract deficits in social vocalizations. Our study represents one of the few available studies focused not only on the consequences of negative life events in this species, but also the protective role of relatively short periods of positive social activity on subsequent emotional development. © 2010 Wiley Periodicals, Inc.
