The role of external factors in affect-sharing and their neural bases.

Affect-sharing, the ability to vicariously feel another person's emotions, is the primary component of empathy that is typically thought to rely on the observer's capacity to feel the emotions of others. However, external signals, such as the target's physical characteristics, have been demonstrated to influence affect-sharing in the neuroscientific literature that speaks to the underappreciated role of external factors in eliciting affect-sharing. We consider factors that influence affect-sharing, including physical cues, emotional cues, situational factors, and observer-target relationships, as well as the neural circuits involved in these processes. Our review reveals that, while neural network activation is primarily responsible for processing affect-sharing, external factors also co-activate a top-down cognitive processing network to modulate the conscious process of affect-sharing. From this knowledge, an integrative framework of external factor interactions with affect-sharing are explained in detail. Finally, we identify critical areas for future research in social and affective neuroscience, including research gaps and incorporation of ecologically valid paradigms.

Why Do People Sometimes Wear an Anonymous Mask? Motivations for Seeking Anonymity Online.

Anonymous environments are more accessible than ever. As such, it is important to understand not only how anonymity can change human behavior but also why people are motivated to seek anonymity in online spaces. In four studies, we investigated differences in motivations for seeking anonymity online and their associations with related dispositional factors and online behavior. We found that some people were motivated to seek anonymity to self-express or behave toxically. Both motivations to seek anonymity were associated with low self-concept clarity and high Machiavellianism but differed in their relation to traits such as self-consciousness and psychopathy. Further analyses suggested that people selectively engage in behaviors in anonymous online environments, in line with the specific gratifications they seek through anonymity. We conclude that people seek anonymity to pursue self- or other-related goals that are otherwise more difficult or costly to pursue when identifiable.

A functionalist approach to online trolling.

Online trolling is often linked to sadism and psychopathy. Yet, little research has assessed why people high in these traits seek online environments to achieve their nefarious goals. We employ a functionalist approach to examine whether people high in sadism and psychopathy are motivated to seek the affordances of online environments (e.g., anonymity) to reveal their malevolent self-aspects by engaging in trolling behavior. A sample of 515 university undergraduates (Mage = 20.47) read vignettes depicting trolling incidents and rated the acceptability of the perpetrators' actions and whether they had ever written similar comments. Participants then completed measures of psychopathy, sadism, and toxic anonymous motivations. We find that toxic anonymous motivations partially mediate the relationship between psychopathy and sadism, and online trolling. Whereas trolling is often understood through its underlying personality traits, toxic motivations to seek anonymity may be a more proximal predictor of who is likely to troll online.

Empathic Conservatives and Moralizing Liberals: Political Intergroup Empathy Varies by Political Ideology and Is Explained by Moral Judgment.

Empathy has the potential to bridge political divides. Here, we examine barriers to cross-party empathy and explore when and why these differ for liberals and conservatives. In four studies, U.S. and U.K. participants (total N = 4,737) read hypothetical scenarios and extended less empathy to suffering political opponents than allies or neutral targets. These effects were strongly shown by liberals but were weaker among conservatives, such that conservatives consistently showed more empathy to liberals than liberals showed to conservatives. This asymmetry was partly explained by liberals' harsher moral judgments of outgroup members (Studies 1-4) and the fact that liberals saw conservatives as more harmful than conservatives saw liberals (Studies 3 and 4). The asymmetry persisted across changes in the U.S. government and was not explained by perceptions of political power (Studies 3 and 4). Implications and future directions are discussed.

Empathy moderates the relationship between cognitive load and prosocial behaviour.

Cognitive load reduces both empathy and prosocial behaviour. However, studies demonstrating these effects have induced cognitive load in a temporally limited, artificial manner that fails to capture real-world cognitive load. Drawing from cognitive load theory, we investigated whether naturally occurring cognitive load from the ongoing COVID-19 pandemic moderated the relationship between empathy and prosocial behaviour (operationalised as support for public health measures). This large study in an Australian sample (N = 600) identified negative relationships between pandemic fatigue, empathy for people vulnerable to COVID-19, and prosocial behaviour, and a positive relationship between empathy and prosocial behaviour. Additionally, we found that the negative effect of the pandemic on prosocial behaviour depended on empathy for vulnerable others, with pandemic fatigue's effects lowest for those with the highest empathy. These findings highlight the interrelationships of cognitive load and empathy, and the potential value of eliciting empathy to ease the impact of real-world cognitive load on prosocial behaviour.

The Disinhibiting Effects of Anonymity Increase Online Trolling.

Research assessing online trolling-a behavior designed to trigger or antagonize other users for entertainment-has largely focused on identifying individual differences that underlie the behavior. Less attention has been given to how situational factors influence trolling, such as the disinhibiting effects of anonymity. In this study, we evaluated the roles of both individual differences and levels of anonymity in online trolling. We assessed these through experimentation, a relatively novel approach in trolling research. Australian undergraduate students (n = 242, 167 women, 75 men, Mage = 21.18) were allocated to one of three conditions: an anonymous condition where they were not visible to one another, an identifiable condition where they were visible to one another, or an external condition where they completed the study outside of a controlled laboratory environment. Participants first read a short news article before interacting in an online group discussion where participants could chat freely. The first comment participants wrote was later coded for trolling. Participants also completed assessments of psychopathy, sadism, and a global assessment of trolling. As predicted, participants in the anonymous condition trolled more than those in the identifiable condition. No differences were seen between these two conditions and the external condition. Analyses also revealed that sadism and global trolling were positively associated with trolling in the chat room, but psychopathy showed no association. These results demonstrate the importance of both individual differences and the disinhibiting effects of anonymity when investigating the complex nature of trolling.

Tears of sadness reduce others' gazing toward the eyes.

Emotional tears enhance perceptions of sadness and promote helping behaviors, but it is yet to be established whether they also influence the way we gaze at emotional faces. This is an important question to address given that how people visually attend to faces plays a critical role during social interaction and may also be used to regulate emotional arousal. We used eye-tracking to quantify the time spent gazing to the eyes and mouths of emotional faces. Participants' (N = 131) gaze patterns were monitored while they viewed stimuli that were manipulated to have tears present or absent. The key finding to emerge was that participants gazed less at the eyes of faces when tears were present compared with absent, suggesting that perceiving tears may be emotionally aversive. These findings are discussed in relation to prior work that suggests eye-gaze is used to regulate emotional arousal. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The relationship between testosterone and social cognition in younger and older adults.

Testosterone (T) has been linked to poorer social cognition in younger adults. Because social cognition and T both decline with normal aging, a different type of relationship may exist between T and social cognition in late adulthood. To test this possibility, younger and older adults provided a salivary T sample and completed two social cognition tasks. The results showed that age-group was a significant moderator in the relationship between T and theory of mind (ToM) performance for males, such that T was a negative predictor of ToM in younger males and a positive predictor of ToM in older age. No relationships were identified for females. These findings show for the first time that T is differentially related to ToM in the early and later stages of the male adult lifespan, and are discussed in relation to prior work that suggests T may have neuroprotective effects in older age.

Social neuroscience is more than the study of the human brain: The legacy of John Cacioppo.

John Cacioppo passed away in 2018, leaving a legacy of profound methodological, theoretical, and inferential contributions to social neuroscience. This paper serves as an introduction to the nine articles that comprise this special issue in honor of John Cacioppo's work in social neuroscience. Although he made many contributions to psychology, here we briefly review four milestones in Cacioppo's career that had important implications specifically for the development of social neuroscience today: (1) an early research focus on cardiovascular and facial EMG measurement, (2) the training of others, (3) the importance of sound inference, and (4) the definition of social neuroscience. In sum, we argue that John Cacioppo envisioned social neuroscience as having multiple levels of explanation and requiring multiple kinds of physiological evidence. It is not all just the brain!

Social exclusion enhances affiliative signaling.

Reciprocating smiles is important for maintaining social bonds as it both signals affiliative intent and elicits affiliative responses. Feelings of social exclusion may increase mimicry as a means to regulate affiliative bonds with others. In this study, we examined whether feelings of exclusion lead people to selectively reciprocate the facial expressions of more affiliative-looking people. Participants first wrote about either a time they were excluded or a neutral event. They then classified 20 smiles-half spontaneous smiles and half posed. Facial electromyography recorded smile muscle activity. Excluded participants distinguished the two smile types better than controls. Excluded participants also showed greater zygomaticus major (mouth smiling) activity toward enjoyment smiles compared to posed smiles; control participants did not. Orbicularis oculi (eye crinkle) activity matched that of the smile type viewed, but did not vary by exclusion condition. Affiliative social regulation is discussed as a possible explanation for these effects.

Negative valence specific deficits in judgements of musical affective quality in alexithymia.

Alexithymia is characterised by a lack of words for emotional experiences and it has been implicated in deficits in emotion processing. Research in this area has typically focused on judgements of discrete emotions rather than of affect, which is a precursor to emotion construction. In the current study, higher alexithymia was predicted to be related to more neutral judgements of valence and arousal of music representing a range of emotions. Participants (N = 162) listened to ten 15-second musical pieces that represented five target emotions (happy, sad, tender, angry, and fearful) and rated the valence and arousal of each. Participants also listed emotion words they knew to be expressed in music. Analyses revealed that alexithymia was not related to the number of emotion words generated but was related to valence-specific affect judgements of music. Participants higher in alexithymia rated sad, angry, and fearful pieces as more neutral in valence and arousal. Alexithymia was not related to ratings of valence or arousal for happy and tender pieces. These findings suggest that perceptual deficits in alexithymia may be specific to negative emotions. Our results are consistent with the idea that alexithymia is related to the direction of attention away from negative stimuli.

Using crying to cope: Physiological responses to stress following tears of sadness.

This research tested the hypothesis that emotional crying facilitates coping and recovery, specifically through physiological changes that occur during crying. Female undergraduate students (N = 197) were randomly assigned to either a sad or neutral condition using short videos. Sad videos were selected for their extreme emotion elicitation. We predicted that compared to those who did not cry to the stimuli and those who were exposed to neutral videos, people who cried would (a) be able to withstand a stressful task for longer; (b) show lower levels of cortisol following crying and exposure to the stressor; and (c) have faster recovery (i.e., return to baseline levels of affect). The final groups consisted of the neutral group (n = 65), sad criers (n = 71), and sad noncriers (n = 61). After a 5-min baseline period, participants watched either the sad or neutral videos for 17 min and then completed a physical stressor (cold pressor test). Heart rate and respiration were continuously recorded, whereas salivary samples for cortisol were taken at 4 separate time points during testing. Analyses revealed no differences between the 3 groups in time withstanding the stressor or cortisol changes. Respiration rate, however, increased in the neutral group and noncriers while watching the videos, with criers' respiration remaining stable. Furthermore, heart rate was found to decelerate just before crying, with a return to baseline during the first crying period. These results suggest that crying may assist in generally maintaining biological homeostasis, perhaps consciously through self-soothing via purposeful breathing and unconsciously through regulation of heart rate.

The Relationship of Gender Roles and Beliefs to Crying in an International Sample.

This study aimed to (1) investigate the variation in self ascription to gender roles and attitudes toward gender roles across countries and its associations with crying behaviors, emotion change, and beliefs about crying and (2) understand how the presence of others affects our evaluations of emotion following crying. This was a large international survey design study (N = 893) conducted in Australia, Croatia, the Netherlands, Thailand, and the United Kingdom. Analyses revealed that, across countries, gender, self-ascribed gender roles, and gender role attitudes (GRA) were related to behavioral crying responses, but not related to emotion change following crying. How a person evaluates crying, instead, appeared to be highly related to one's beliefs about the helpfulness of crying, irrespective of gender. Results regarding crying when others were present showed that people are more likely both to cry and to feel that they received help around a person that they know, compared to a stranger. Furthermore, closeness to persons present during crying did not affect whether help was provided. When a crier reported that they were helped, they also tended to report feeling better following crying than those who cried around others but did not receive help. Few cross-country differences emerged, suggesting that a person's responses to crying are quite consistent among the countries investigated here, with regard to its relationship with a person's gender role, crying beliefs, and reactions to the presence of others.

Children's perceptions of the moral worth of live agents, robots, and inanimate objects.

This study examined children's moral concern for robots relative to living and nonliving entities. Children (4-10 years of age, N = 126) watched videos of six different entities having a box placed over them that was subsequently struck by a human hand. Children were subsequently asked to rate the moral worth of each agent relating to physical harm. Children afforded robotic entities less moral concern than living entities but afforded them more moral concern than nonliving entities, and these effects became more pronounced with age. Children's tendency to ascribe mental life to robotic and nonliving entities (but not living entities) predicted moral concern for these entities. However, when asked to make moral judgments relating to giving the agent away, children did not distinguish between nonliving and robotic agents and no age-related changes were identified. Moreover, the tendency to ascribe mental life was predictive of moral concern only for some agents but not others. Overall, the findings suggest that children consider robotic entities to occupy a middle moral ground between living and nonliving entities and that this effect is partly explained by the tendency to ascribe mental life to such agents. They also demonstrate that moral worth is a complex multifaceted concept that does not demonstrate a clear pattern across different ontological categories.

A meta-analysis of the emotional victim effect for female adult rape complainants: Does complainant distress influence credibility?

Rape cases have a disproportionately high attrition rate and low conviction rate compared with other criminal offenses. Evaluations of a rape complainant's credibility often determine whether a case progresses through the criminal justice system. Even though emotional demeanor is not related to witness honesty or accuracy, distressed rape complainants are perceived to be more credible than complainants who present with controlled affect. To understand the extent and robustness of the influence of emotional demeanor on credibility judgments of female adult rape complainants, we conducted a systematic review, meta-analysis, and p-curve analysis of the experimental simulated decision-making literature on the influence of complainant emotional demeanor on complainant credibility. The meta-analysis included 20 studies with participants who were criminal justice professionals (e.g., police officers and judges), community members, and mock jurors (N = 3128). Results suggest that distressed demeanor significantly increased perceptions of complainant credibility, with a small to moderate effect size estimate. Importantly, the results of p-curve analysis suggest that reporting bias is not a likely explanation for the effect of emotional demeanor on rape complainant credibility. Sample type (whether perceivers were criminal justice professionals or prospective jurors) and stimulus modality (whether perceivers read about or watched the complainant recount the alleged rape) were not found to moderate the effect size estimate. These results suggest that effective methods of reducing reliance on emotional demeanor to make credibility judgments about rape complainants should be investigated to make credibility assessments fairer and more accurate.

The influence of tears on older and younger adults' perceptions of sadness.

Prior studies have shown that older adults perceive sadness differently relative to younger adults. However, the stimuli used to test older adults' perceptions of sadness have been limited by the fact that they have not included emotional tears-a salient emotional cue that has previously been shown to enhance perceptions of sadness in younger adults. This study reports three experiments that test whether the presence of tears differentially affects older and younger adults' perceptions of sadness. Experiment 1 was a laboratory-based experiment and also assessed facial mimicry responses using electromyography (EMG). Experiments 2 and 3 were conducted online. Across all three experiments, participants rated faces as showing greater sadness when tears were present compared to absent, and most critically, participant age did not moderate this effect-young and older adults responded equivalently to the presence of tears. Another finding to emerge across all experiments was that older faces were consistently rated as showing more sadness than younger faces, suggesting that there may be a bias toward attributing more sadness to people in older age. The facial EMG data showed that both age groups exhibited greater frowning (relative to smiling) responses when viewing the sad faces, but this effect was not moderated by the presence of tears. Taken together, the data from these three experiments show stability in terms of how younger and older adults respond to the presence of tears; in both age groups, behavioral responses to sadness are equivalently enhanced.

Does crying help? Development of the beliefs about crying scale (BACS).

Crying is often considered to be a positive experience that benefits the crier, yet there is little empirical evidence to support this. Indeed, it seems that people hold a range of appraisals about their crying, and these are likely to influence the effects of crying on their emotional state. This paper reports on the development and psychometric validation of the Beliefs about Crying Scale (BACS), a new measure assessing beliefs about whether crying leads to positive or negative emotional outcomes in individual and interpersonal contexts. Using 40 preliminary items drawn from a qualitative study, an exploratory factor analysis with 202 participants (50% female; aged 18-84 years) yielded three subscales: Helpful Beliefs, Unhelpful-Individual Beliefs, and Unhelpful-Social Beliefs, explaining 60% of the variance in the data. Confirmatory factor analysis on the 14-item scale with 210 participants (71% female; aged 17-48 years) showed a good fit to the three factors. The subscales showed differential relationships with measures of personality traits, crying proneness, emotion regulation and expressivity, and emotional identification (alexithymia). The BACS provides a nuanced understanding of beliefs about crying in different contexts and helps to explain why crying behaviour may not always represent positive emotion regulation for the crier.

Intranasal oxytocin does not alter initial perceptions of facial trustworthiness in younger or older adults.

BACKGROUND: Oxytocin is a neuropeptide involved in a range of social processes, and prior research has shown that intranasal oxytocin (iOT) may enhance trusting behaviors. However, it is unclear whether iOT influences perceptions of whether a face is trustworthy. In addition, no studies in this literature have investigated whether the participant's age may play a moderating role in the effects of iOT on trust. AIMS: We aimed to examine for the first time whether iOT influences perceptions of facial trustworthiness and eye-gaze patterns and, if so, whether age moderates these iOT effects. METHODS: One hundred and eighteen participants took part in a randomized, double-blind, placebo-controlled, within-groups study. Participants made judgments about the perceived trustworthiness of a series of faces while their eye movements were monitored. RESULTS: Younger and older adults differed in their judgments of facial trustworthiness. However, most critically, iOT had no effect on these judgments for either age group. For the eye-tracking data, prior age effects in attending to the stimuli were replicated, with older adults gazing less at the eye region and more at the mouth region relative to younger adults. However, iOT had no effect on eye gaze. CONCLUSIONS: These findings are discussed in relation to the growing body of literature that suggests that the effect of iOT on social processing is complex and may not be as robust as first thought.

The burden of online friends: the effects of giving up Facebook on stress and well-being.

People occasionally choose to cut themselves off from their online social network by taking extended breaks from Facebook. This study investigated whether abstaining from Facebook reduces stress but also reduces subjective well-being because of the resulting social disconnection. Participants (138 active Facebook users) were assigned to either a condition in which they were instructed to give up Facebook for 5 days or continue to use Facebook as normal. Perceived stress and well-being, as well as salivary cortisol, were measured before and after the test period. Relative to those in the Facebook Normal condition, those in the No Facebook condition experienced lower levels of cortisol and life satisfaction. Our results suggest that the typical Facebook user may occasionally find the large amount of social information available to be taxing, and Facebook vacations could ameliorate this stress-at least in the short term.

Intranasal oxytocin does not reduce age-related difficulties in social cognition.

Oxytocin is a neuropeptide that plays a key role in social processing and there are several studies suggesting that intranasally administered oxytocin may enhance social cognitive abilities and visual attention in healthy and clinical groups. However, there are very few studies to date that have investigated the potential benefits of intranasal oxytocin (iOT) on older adults' social cognitive abilities. This is a surprising omission, because relative to their younger counterparts, older adults also exhibit a range of social cognitive difficulties and also show differences in the way they visually attend to social information. Therefore, we tested the effect of iOT (24 IU) versus a placebo spray on 59 older and 61 younger adults' social cognitive abilities and visual attention using a double-blind placebo-controlled within-groups design. While iOT provided no overall age-related benefit on social cognitive abilities, the key finding to emerge was that iOT improved ToM ability in both age-groups when the task had minimal contextual information, but not when the task had enriched contextual information. Interestingly, iOT had gender specific effects during a ToM task with minimal context. For males in both age-groups, iOT reduced gazing to the social aspects of the scenes (i.e., faces & bodies), and for females, iOT eliminated age differences in gaze patterns that were observed in the placebo condition. These effects on eye-gaze were not observed in a very similar ToM task that included more enriched contextual information. Overall, these findings highlight the interactive nature of iOT with task related factors (e.g., context), and are discussed in relation to the social salience hypothesis of oxytocin.
