The antagonistic relationship between aversive and appetitive emotional states in rats as studied by pharmacologically-induced ultrasonic vocalization from the nucleus accumbens and lateral septum

Rats can emit 22-kHz or 50-kHz ultrasonic vocalizations (USVs) in negative, as well as positive contexts which index their emotional state. 22-kHz USVs are emitted during aversive contexts and can be initiated by activation of the ascending cholinergic pathways originating from the laterodorsal tegmental nucleus or initiated pharmacologically by injection of cholinergic agonists into target areas of these pathways (medial cholinoceptive vocalization strip). Conversely, 50-kHz USVs are emitted during positive pro-social contexts and can be initiated by stimulation of ascending dopaminergic pathways originating from the ventral tegmental area or by injection of dopamine agonists into target areas of these pathways (nucleus accumbens shell). Recently, we have shown an inhibitory effect a positive emotional state has on the emission of carbachol-induced 22-kHz USVs from the anterior hypothalamic/medial preoptic area. However, this structure is a fragment of that cholinoceptive vocalization strip. We wanted to examine if we could observe similar effect when the aversive state is induced from the lateral septum, the most rostral division of the cholinoceptive vocalization strip. The results supported previous findings. First, microinjection of the dopamine agonist R-(-)-apomorphine into the nucleus accumbens shell resulted in increased emission of frequency modulated (FM) 50-kHz USVs that are regarded as signals expressing a positive emotional state in rats. Second, FM 50-kHz USVs and not flat (F) 50-kHz USVs were able to decrease 22-kHz USVs induced by microinjections of carbachol into the lateral septum. This research provides further support to the hypothesis that the initiation of a positive emotional state functionally antagonizes initiation of a negative emotional state in rats.

Four- and 5-Year-Olds Infer Differences in Relative Ability and Appropriately Allocate Roles to Achieve Cooperative, Competitive, and Prosocial Goals

Preschoolers are sensitive to differences in individuals’ access to external resources (e.g., tools) in division of labor tasks. However, little is known about whether children consider differences in individuals’ internal resources (e.g., abilities) and whether children can flexibly allocate roles across different goal contexts. Critically, factors that are relevant to role allocation in collaborative contexts may be irrelevant in competitive and prosocial ones. In three preregistered experiments, we found that 4- and 5-year-olds (mean: 54 months; range: 42–66 months; N = 132) used age differences to infer relative ability and appropriately allocate the harder and easier of two tasks in a dyadic cooperative interaction (Experiment 1), and appropriately ignored relative ability in competitive (Experiment 2) and prosocial (Experiment 3) contexts, instead assigning others the harder and easier roles, respectively. Thus, 3-and-a-half- to 5-year-olds evaluate their own abilities relative to others and effectively allocate roles to achieve diverse goals.

Automatic imitation of pro- and antisocial gestures: Is implicit social behavior censored?

According to social reward theories, automatic imitation can be understood as a means to obtain positive social consequences. In line with this view, it has been shown that automatic imitation is modulated by contextual variables that constrain the positive outcomes of imitation. However, this work has largely neglected that many gestures have an inherent pro- or antisocial meaning. As a result of their meaning, antisocial gestures are considered taboo and should not be used in public. In three experiments, we show that automatic imitation of symbolic gestures is modulated by the social intent of these gestures. Experiment 1 (N=37) revealed reduced automatic imitation of antisocial compared with prosocial gestures. Experiment 2 (N=118) and Experiment 3 (N=118) used a social priming procedure to show that this effect was stronger in a prosocial context than in an antisocial context. These findings were supported in a within-study meta-analysis using both frequentist and Bayesian statistics. Together, our results indicate that automatic imitation is regulated by internalized social norms that act as a stop signal when inappropriate actions are triggered.

Waiting To Give: Stated and Revealed Preferences

We estimate and compare the effect of increased time costs on consumer satisfaction and behavior. We are able to move beyond the existing literature, which focuses on satisfaction and intention, and estimate the effect of waiting time on return behavior. Further, we do so in a prosocial context and our measure of cost is the length of time a blood donor spends waiting. We find that relying on satisfaction data masks important time cost sensitivities; namely, it is not how the donor feels about the wait time that matters for return behavior, but rather the actual duration of the wait. Consistent with theory we develop, our results indicate that waiting has a significant longer-term social cost: we estimate that a 38% increase (equivalent to one standard deviation) in the average wait would result in a 10% decrease in donations per year.

Change is an emotional state of mind: Behavioral responses to online petitions

Scholars are increasingly concerned about the rising level of negativity in social media sites. This negativity has found its way into sites that are supposedly intended for prosocial civic engagement. To examine how hostility impacts behavior in a user-generated, prosocial context, an experimental study was conducted using an online petition modeled after those posted to the website Change.org . This study examines whether negativity causes a contagion effect leading to more negativity and the different types of negativity that may occur. Results suggest that when users read negative-toned petitions, a contagion effect increases both anger and anxiety. However, our findings are not consistent with previous literature that argues anger leads to increased proactive behavior. Instead, we find that while anxiety leads to an increase in petition-related action, anger does not. These findings have important theoretical and practical implications for scholars and those looking to participate in social justice via online platforms.

Neurocomputational mechanisms of prosocial learning and links to empathy

Reinforcement learning theory powerfully characterizes how we learn to benefit ourselves. In this theory, prediction errors-the difference between a predicted and actual outcome of a choice-drive learning. However, we do not operate in a social vacuum. To behave prosocially we must learn the consequences of our actions for other people. Empathy, the ability to vicariously experience and understand the affect of others, is hypothesized to be a critical facilitator of prosocial behaviors, but the link between empathy and prosocial behavior is still unclear. During functional magnetic resonance imaging (fMRI) participants chose between different stimuli that were probabilistically associated with rewards for themselves (self), another person (prosocial), or no one (control). Using computational modeling, we show that people can learn to obtain rewards for others but do so more slowly than when learning to obtain rewards for themselves. fMRI revealed that activity in a posterior portion of the subgenual anterior cingulate cortex/basal forebrain (sgACC) drives learning only when we are acting in a prosocial context and signals a prosocial prediction error conforming to classical principles of reinforcement learning theory. However, there is also substantial variability in the neural and behavioral efficiency of prosocial learning, which is predicted by trait empathy. More empathic people learn more quickly when benefitting others, and their sgACC response is the most selective for prosocial learning. We thus reveal a computational mechanism driving prosocial learning in humans. This framework could provide insights into atypical prosocial behavior in those with disorders of social cognition.

Dimensionality in adolescent prosocial tendencies: Individual differences in serving others versus serving the self

The purpose of the present research was to determine whether adolescents prosocial tendencies can be distinguished by serving others versus serving the self, and, further, to support that distinction through their associations with empathic (empathic concern, perspective taking, personal distress) versus egoistic traits (need for approval, narcissism, psychopathy). Empathy was hypothesized to be linked to interpersonal and high-cost prosocial contexts, whereas egoistic traits were hypothesized to be linked to contexts offering self-aggrandizement. High school students (n=272; 15–18years) completed questionnaires online. Results revealed that empathy and concerns about others’ approval associated positively with emotional responsivity, dire, compliancy, and anonymous prosocial tendencies. Concerns about approval also predicted public and opportunistic tendencies. Egoistic traits related to adolescents’ public and opportunistic prosocial behavior. Findings demonstrate an individual difference by context variation, supporting the multidimensionality of prosocial behavior and its underlying motives.

Do children understand that people selectively conceal or express emotion?

This study examined whether children understand that people selectively conceal or express emotion depending upon the context. We prepared two contexts for a verbal display task for 70 first-graders, 80 third-graders, 64 fifth-graders, and 71 adults. In both contexts, protagonists had negative feelings because of the behavior of the other character. In the prosocial context, children were instructed that the protagonist wished to spare the other character’s feelings. In contrast, in the real-emotion context, children were told that the protagonist was fed up with the other character’s behavior. Participants were asked to imagine what the protagonists would say. Adults selected utterances with positive or neutral emotion in the prosocial context but chose utterances with negative emotion in the real-emotion context, whereas first-graders selected utterances with negative emotion in both contexts. In the prosocial context, the proportion of utterances with negative emotion decreased from first-graders to adults, whereas in the real-emotion context the proportion was U-shaped, decreasing from first- to third-graders and increasing from fifth-graders to adults. Further, performance on both contexts was associated with second-order false beliefs as well as second-order intention understanding. These results indicate that children begin to understand that people selectively conceal or express emotion depending upon context after 8 to 9 years. This ability is also related to second-order theory of mind.

Children's utilization of emotion expectancies in moral decision-making

This study investigated the relevance of emotion expectancies for children's moral decision-making. The sample included 131 participants from three different grade levels (M = 8.39 years, SD = 2.45, range 4.58-12.42). Participants were presented a set of scenarios that described various emotional outcomes of (im)moral actions and asked to decide what they would do if they were in the protagonists' shoes. Overall, it was found that the anticipation of moral emotions predicted an increased likelihood of moral choices in antisocial and prosocial contexts. In younger children, anticipated moral emotions predicted moral choice for prosocial actions, but not for antisocial actions. Older children showed evidence for the utilization of anticipated emotions in both prosocial and antisocial behaviours. Moreover, for older children, the decision to act prosocially was less likely in the presence of non-moral emotions. Findings suggest that the impact of emotion expectancies on children's moral decision-making increases with age. Contrary to happy victimizer research, the study does not support the notion that young children use moral emotion expectancies for moral decision-making in the context of antisocial actions.

Helping Fellow Beings

People are often reluctant to comply with social causes because doing so may involve personal sacrifices of time, money, and effort for benefits that are shared by other members of society. In an effort to increase compliance, government agencies and public institutions sometimes employ financial tools to promote social causes. However, employing financial tools to induce prosocial behavior is expensive and often ineffective. We propose that anthropomorphizing a social cause is a practical and inexpensive tool for increasing compliance with it. Across three prosocial contexts, we found that individuals exposed to a message from an anthropomorphized social cause, compared with individuals exposed to a message relating to a nonanthropomorphized social cause, were more willing to comply with the message. This effect was mediated by feelings of anticipatory guilt experienced when they considered the likely consequences of not complying with the cause. The theoretical and practical implications of these findings are discussed.

Virtually justifiable homicide: The effects of prosocial contexts on the link between violent video games, aggression, and prosocial and hostile cognition

Previous work has shown that playing violent video games can stimulate aggression toward others. The current research has identified a potential exception. Participants who played a violent game in which the violence had an explicitly prosocial motive (i.e., protecting a friend and furthering his nonviolent goals) were found to show lower short-term aggression (Study 1) and show higher levels of prosocial cognition (Study 2) than individuals who played a violent game in which the violence was motivated by more morally ambiguous motives. Thus, violent video games that are framed in an explicitly prosocial context may evoke more prosocial sentiments and thereby mitigate some of the short-term effects on aggression observed in previous research. While these findings are promising regarding the potential aggression-reducing effects of prosocial context, caution is still warranted as a small effect size difference (d = .2-.3), although nonsignificant, was still observed between those who played the explicitly prosocial violent game and those who played a nonviolent game; indicating that aggressive behavior was not completely eliminated by the inclusion of a prosocial context for the violence.

The role of emotion expectancies in adolescents’ moral decision making

This study investigated the impact of emotion expectancies on adolescents’ moral decision making in hypothetical situations. The sample consisted of 160 participants from three different grade levels (mean age = 15.79 years, SD = 2.96). Participants were confronted with a set of scenarios that described various emotional outcomes of (im)moral actions and needed to decide what they would do if they were in the protagonist’s shoes. Findings demonstrate that emotion expectancies differentially influenced adolescents’ hypothetical decision making in antisocial versus prosocial behavioral contexts. Whereas negatively charged self-evaluative emotions over failing to act morally (e.g., guilt) were the strongest predictor for moral choice in antisocial behavioral contexts, positively charged self-evaluative emotions over acting morally (e.g., pride) most strongly predicted moral choice in prosocial contexts. Older adolescents paid greater attention to outcome-oriented emotions that make the decision to act morally less attractive (e.g., regret). Overall, the study suggests that emotion expectancies influence moral decision making in unique and meaningful ways.

Aggressive and Prosocial Peer Group Functioning: Effects on Children's Social, School, and Psychological Adjustment

AbstractThis study examined the effects of aggressive and prosocial contexts of peer groups on children's socioemotional and school adjustment. Data on informal peer groups, social functioning, and different aspects of adjustment were collected from multiple sources in a sample of elementary school children (149 boys, 181 girls; M age = 10 years). Multilevel analyses indicated that group aggressive and prosocial orientations made direct contributions to children's social, school, and psychological functioning. Group contexts also moderated the individual‐level relations between social behavior and self‐perceptions; prosocial behavior was associated with social or scholastic self‐perceptions more evidently in low prosocial and high aggressive groups. The results suggest that the peer group is an important context for children's performance and adjustment in various domains.

Human kin recognition is self- rather than family-referential

Inclusive fitness theory predicts that organisms will tend to help close kin more than less related individuals. In a variety of birds and mammals, relatives are recognized by comparing their phenotype to an internal representation or template, which might be learned through either repeated exposure to family members or self-inspection. Mirrors are ubiquitous now, but were absent during our evolutionary history; hence it is hard to predict, and empirically unknown, whether human kin recognition is family- or self-referential. Here we put this issue to the strongest possible test by comparing nepotistic behaviour towards self- versus co-twin-resemblant individuals. Seventy monozygotic and dizygotic twins were shown same-sex faces, covertly manipulated to resemble either themselves or their co-twin, and indicated which individual they would prefer in two prosocial contexts. Self-resemblant faces were significantly preferred to twin-resemblant faces, showing that visual information about the self supersedes that about close family members in the kin-recognition template. Because, under conditions of paternal uncertainty, a reliable family-referent template could be based only on one's mother and maternal relatives, a unique advantage of self-referent phenotype matching is the possibility of (consciously or unconsciously) identifying one's father and paternal relatives as kin.

Pro-social motive promotes early understanding of false belief

AbstractEver since Premack & Woodruff's classic article^1^, which introduced the term "theory of mind", researchers have claimed that strategic deception is the most natural behavioural consequence of understanding false belief. Here we challenge that claim, and provide evidence for the first time that the earliest manifestation of false belief understanding in human development is found in young children's emerging pro-social behaviours. In a modified false belief task, children were asked either to choose one protagonist they should help to find the object (the pro-social context), or to choose one they need to deceive so that none of the protagonists can find the object (the competitive context). The results show that the pro-social motive, but not the competitive motive, boosts early false belief understanding. This is most clearly contrasted with findings that apes, our closest living relatives, are capable of intentionally manipulating others by concealing information only under competitive motives, not under cooperative alternatives. Thus, the current findings are the strongest to date that sophisticated understanding of others' belief in humans has its unique origin, separate from the primate origin at some point in recent evolution, when cooperative and communicative motives played an essential role for their survival.

Adolescent Perceptions of Appropriate Parental Reactions in Moral and Conventional Social Domains

AbstractResearch suggests that adolescents' ratings of the appropriateness of parental reactions are influenced by several constructs, including adolescents' perceptions of the type of parental reaction, the emotions felt by the adolescent and parental intentions. However, little is known regarding how these constructs are differentially predictive of appropriateness in different socialization contexts. One hundred and twenty‐two adolescents (mean age = 16.87 years) answered questions regarding past situations in antisocial and prosocial contexts, and in moral and conventional domains. Different parental reactions were reported across moral and conventional domains. In addition, the appropriateness of parental responses varied across domain. Namely, in antisocial contexts, parental responses of yelling and punishing were seen as more appropriate in moral than conventional domains. In prosocial contexts, no action from the parent was seen as less appropriate in conventional than moral domains. In addition, adolescents' perceptions were more strongly associated with adolescents' ratings of appropriateness in conventional than moral social domains. These findings highlight the importance of considering both moral context and social domain when examining adolescents' perceptions of appropriate parental reactions and internalization of values.

Facial resemblance increases the attractiveness of same–sex faces more than other–sex faces

Our reactions to facial self-resemblance could reflect either specialized responses to cues of kinship or by-products of the general perceptual mechanisms of face encoding and mere exposure. The adaptive hypothesis predicts differences in reactions to self-resemblance in mating and prosocial contexts, while the by-product hypothesis does not. Using face images that were digitally transformed to resemble participants, I showed that the effects of resemblance on attractiveness judgements depended on both the sex of the judge and the sex of the face being judged: facial resemblance increased attractiveness judgements of same-sex faces more than other-sex faces, despite the use of identical procedures to manipulate resemblance. A control experiment indicated these effects were caused neither by lower resemblance of other-sex faces than same-sex faces, nor by an increased perception of averageness or familiarity of same-sex faces due to prototyping or mere exposure affecting only same-sex faces. The differential impact of self-resemblance on our perception of same-sex and other-sex faces supports the hypothesis that humans use facial resemblance as a cue of kinship.
