What if a Social Robot Excluded You?: Using a Conversational Game to Study Social Exclusion in Teen-robot Mixed Groups
... In 120 Cyberball studies, need-threat has been widely demonstrated [7]. Some studies also proved need-threat when ignored by computers [10,37] or robots [6,15,28]. However, other forms of social exclusion like averted eye gazes, micro-agressions, or hurtful laughter have not been explored in HAI yet. ...
In a world where humans and technical agents (e.g., robots, AI) work collaboratively, processes of social inclusion and exclusion in human-agent interaction (HAI) gain importance. However, the current focus of social exclusion in HAI is too narrowminded and neglects many forms of social exclusion (e.g., averted eye gazes, microaggressions, hurtful laughter). To change this, the effects of different types of social exclusion will be explored in a series of experiments against the background of William's need-threat model [34]. By doing so, we will test the transferability of the model, build a HAI-specific taxonomy, and derive prevention strategies. We look forward to interdisciplinary discussions about this topic and hope to receive valuable feedback and inspiration for the presented PhD project which has just started a few months ago.
Humans are constantly influenced by others’ behavior and opinions. Importantly, social influence among humans is shaped by reciprocity: we follow more the advice of someone who has been taking into consideration our opinions. In the current work, we investigate whether reciprocal social influence can emerge while interacting with a social humanoid robot. In a joint task, a human participant and a humanoid robot made perceptual estimates and then could overtly modify them after observing the partner’s judgment. Results show that endowing the robot with the ability to express and modulate its own level of susceptibility to the human’s judgments represented a double-edged sword. On the one hand, participants lost confidence in the robot’s competence when the robot was following their advice; on the other hand, participants were unwilling to disclose their lack of confidence to the susceptible robot, suggesting the emergence of reciprocal mechanisms of social influence supporting human-robot collaboration.
People usually prefer to appear with an inclusive and positive attitude to others’ eyes. For this reason, the self-report scales assessing social exclusion intentions are often biased by social desirability. In this work, we present an innovative graphical tool, named Social Exclusion Bench Tool (SEBT), for assessing social exclusion not influenced by social desirability. The tool is based on the consistency between social distance and physical distance evaluation. The results showed that in two samples of adults from Italy (N = 252) and the UK (N = 254), the SEBT positively correlated with self-report measures of social exclusion, but not with the social desirability measure. The tool has been preliminarily evaluated in the context of social exclusion toward migrant people, but it appears a promising instrument for assessing social exclusion intentions toward different social groups.

Social exclusion refers to the experience of being disregarded or rejected by others and has wide-ranging negative consequences for well-being and cognition. Cyberball, a game where a ball is virtually tossed between players, then leads to the exclusion of the research participant, is a common method used to examine the experience of social exclusion. The neural correlates of social exclusion remain a topic of debate, particularly with regards to the role of the dorsal anterior cingulate cortex (dACC) and the concept of social pain. Here we conducted a quantitative meta-analysis using activation likelihood estimation (ALE) to identify brain activity reliably engaged by social exclusion during Cyberball task performance (Studies = 53; total N = 1,817 participants). Results revealed consistent recruitment in ventral anterior cingulate and posterior cingulate cortex, inferior and superior frontal gyri, posterior insula, and occipital pole. No reliable activity was observed in dACC. Using a probabilistic atlas to define dACC, fewer than 15% of studies reported peak coordinates in dACC. Meta-analytic connectivity mapping suggests patterns of co-activation are consistent with the topography of the default network. Reverse inference for cognition associated with reliable Cyberball activity computed in Neurosynth revealed social exclusion to be associated with cognitive terms Social, Autobiographical, Mental States, and Theory of Mind. Taken together, these findings highlight the role of the default network in social exclusion and warns against interpretations of the dACC as a key region involved in the experience of social exclusion in humans.
Research on human-robot collaboration or human-robot teaming, has focused predominantly on understanding and enabling collaboration between a single robot and a single human. Extending human-robot collaboration research beyond the dyad, raises novel questions about how a robot should allocate resources among group members and about what the consequences of such allocation are for a group’s social dynamics and outcomes. Methodological advances are needed to answer these questions allow researchers to collect data about a robot’s impact not only on interactions with the robot but also on interactions of people with each other. This paper presents Robot Assisted Tower Construction, a novel task that allows researchers to examine the impact of a robot’s allocation behavior on the dynamics of a group or team collaborating on a task. By focusing on the question of whether and how a robot’s allocation of resources (wooden blocks required for a building task) affects collaboration dynamics and outcomes, a case is provided of how this task can be applied in a laboratory study with 124 participants to collect data about human robot collaboration that involves a group of people. We highlight the kinds of insights the task can yield and how it can be adapted to various human robot collaboration contexts.
A growing body of research documents the adverse effects of sexualized appearance on people’s attitudes toward women victims of blatant forms of gender violence. However, the impact of sexualization of women victims of subtle forms of gender violence and the moderating role of people’s conservativism on victim blaming remain under-investigated. In the current study, we examined the effects of sexualization on blame attribution to victims of a stranger harassment incident, considering the moderating role of participants’ Right-Wing Authoritarianism (RWA). Two hundred and thirty-six participants (31.8% male; Mage = 30.52, SD = 12.70) completed an RWA scale and then read a fictitious Facebook’s post where the victim herself described the stranger harassment episode that happened down the street (vs. at a house party). The post was presented with a sexualized (vs. non-sexualized) portrayal of the victim. Finally, participants rated the severity of the episode and expressed to what extent they blamed the victim. As predicted, harassment at the house party (vs. down the street) was perceived as less severe, and sexualized (vs. non-sexualized) victims were blamed to a greater extent. Our major results revealed that people’s RWA synergizes with the victim’s sexualization in shaping blame attribution. People with an average and a high level of RWA tend to blame to a greater extent the sexualized victim of stranger harassment, while blame attributions did not change according to victim’s sexualization for people with a low level of RWA.
Three studies examined the effects of randomly assigned messages of social exclusion. In all 3 studies, significant and large decrements in intelligent thought (including IQ and Graduate Record Examination test performance) were found among people told they were likely to end up alone in life. The decline in cognitive performance was found in complex cognitive tasks such as effortful logic and reasoning: simple information processing remained intact despite the social exclusion. The effects were specific to social exclusion, as participants who received predictions of future nonsocial misfortunes (accidents and injuries) performed well on the cognitive tests. The cognitive impairments appeared to involve reductions in both speed (effort) and accuracy. The effect was not mediated by mood.
Human beings naturally assign roles to one another while interacting. Role assignment is a way to organize interpersonal encounters and can result in uncertainty decrease when facing a novel interaction with someone we just met, or even to rediscover new roles within previous relationships. When people interact with synthetic characters – such as robots – it seems they also assign roles to these agents, just as they do with humans. Within the field of human-robot interaction (HRI), robots are being developed to fulfill specific roles. This enables researchers to design concrete behaviors that match the desired role that a robot will play in a given task. It would then be expected that if a robot is developed with such a specific role, users too would assign the same role to that robot. In this paper, we study how children assign roles to an educational robot whose role is established from the beginning of the interaction. Our results show that although the role that the robot played was explicitly presented to children, they end up perceiving and assigning different roles for that robot. Moreover, we conclude that role assignment in educational HRI is a dynamic process in which the perceptions of children regarding the robot change over time as a consequence of continuous interactions.
The present research aims at gaining a better insight on the psychological barriers to the introduction of social robots in society at large. Based on social psychological research on intergroup distinctiveness, we suggested that concerns toward this technology are related to how we define and defend our human identity. A threat to distinctiveness hypothesis was advanced. We predicted that too much perceived similarity between social robots and humans triggers concerns about the negative impact of this technology on humans, as a group, and their identity more generally because similarity blurs category boundaries, undermining human uniqueness. Focusing on the appearance of robots, in two studies we tested the validity of this hypothesis. In both studies, participants were presented with pictures of three types of robots that differed in their anthropomorphic appearance varying from no resemblance to humans (mechanical robots), to some body shape resemblance (biped humanoids) to a perfect copy of human body (androids). Androids raised the highest concerns for the potential damage to humans, followed by humanoids and then mechanical robots. In Study 1, we further demonstrated that robot anthropomorphic appearance (and not the attribution of mind and human nature) was responsible for the perceived damage that the robot could cause. In Study 2, we gained a clearer insight in the processes underlying this effect by showing that androids were also judged as most threatening to the human–robot distinction and that this perception was responsible for the higher perceived damage to humans. Implications of these findings for social robotics are discussed.
Ostracism is such a widely used and powerful tactic that the authors tested whether people would be affected by it even under remote and artificial circumstances. In Study 1, 1,486 participants from 62 countries accessed the authors' on-line experiment on the Internet. They were asked to use mental visualization while playing a virtual tossing game with two others (who were actually computer generated and controlled). Despite the minimal nature of their experience, the more participants were ostracized, the more they reported feeling bad, having less control, and losing a sense of belonging. In Study 2, ostracized participants were more likely to conform on a subsequent task. The results are discussed in terms of supporting K. D. Williams's (1997) need threat theory of ostracism.

The authors forward the hypothesis that social exclusion is experienced as painful because reactions to rejection are mediated by aspects of the physical pain system. The authors begin by presenting the theory that overlap between social and physical pain was an evolutionary development to aid social animals in responding to threats to inclusion. The authors then review evidence showing that humans demonstrate convergence between the 2 types of pain in thought, emotion, and behavior, and demonstrate, primarily through nonhuman animal research, that social and physical pain share common physiological mechanisms. Finally, the authors explore the implications of social pain theory for rejection-elicited aggression and physical pain disorders.
This chapter addresses the question "what kinds of things have minds?" together with some philosophers' speculations regarding mind perceptions, such as whether or not computers have one, or the statement that every mind is in the eye of the beholder. The general conclusion is that mind perception happens on one dimension, and it has not yet been examined whether minds are recognized along several others. A study on the framework of mind perception, accomplished through 2339 surveys on the Mind Survey website, showed that the respondents' personal judgments, in relation to one's experience and agency, are relevant to the dimensions of mind perception.
This research described the utilization of the Unified Theory of Acceptance and Use of Technology (UTAUT) to evaluate a high-level interactive scenario of using Nao Robot in the role of co-presenting in an educative context. Describing the registered result of construct such as Intention of Use, Perceived Enjoyment (PE), Perceived Sociability (PS), and Trust.
The concept of social exclusion has recently gained more attention in the context of online social interactions. However, there is only little data regarding the impact of virtual social exclusion on subsequent real-life social behaviors. Thus, this study set out to examine a virtual version of the common social exclusion scenario, the Cyberball-Paradigm (Williams & Jarvis, 2006), and test for behavioral consequences in a sample of 45 students. Both the virtual characters' agency and the experience of social presence were controlled for. Findings indicate that ostracized individuals show less prosocial behavior in a helping task and keep more seating distance to a confederate than included participants. Also, virtual social exclusion constitutes a significant threat to fundamental human needs like social control, self-esteem and belonging and causes an increase in uncertainty, sadness and anger as well as a decrease in happiness. Avatars and agents seemed to equally endanger human needs and lead to the same seating distance. However, avatar excluded persons also had higher levels of sadness and were less helpful than avatar included persons, who in turn were more confident. Thus, while the Media Equation Concept (Nass & Moon, 2000) holds true for the immediate reaction to social exclusion (i.e., avatars and agents equally threaten fundamental needs), the delayed emotional and behavioral reactions differ for avatars and agents, possibly because they are preceded by cognitive evaluation (c.f.,Temporal Need-Threat Model; Williams, 2009). Implications of these findings for everyday online social interactions (i.e., in MMORPGs) are discussed.

In this study we examined prosocial compensating behavior towards socially excluded ingroup and outgroup members by using a ‘Prosocial Cyberball Game’ in 9–17 year old Dutch adolescents (N = 133). Results showed that adolescents compensated for the social exclusion of an unknown peer in a virtual ball tossing game, by tossing the ball more often to that player in compensation conditions compared to the fair play condition. The proportion of tosses towards the excluded player did not significantly differ as a function of the group status of that player. Although compensating behavior towards ingroup versus outgroup members did not differ, the underlying motivation for this behavior may vary. More empathic concern was associated with more prosocial tosses towards an ingroup member, while more self-reported bullying behavior was associated with less compensating behavior in the outgroup condition. These findings may have practical implications for programs intending to change bystander behavior in bullying situations.

A critical structural form organizing the social arrangement of children's lives is the clique. This primary group colors the character of children's preadolescent years and shapes their socialization to adult life. In this paper we draw on longitudinal participant observation and on depth interviews with advanced elementary-school children to explore the central feature of clique dynamics: the techniques of inclusion and exclusion. Cliques are circles of power wherein leaders attain and wield influence over their followers by cyclically building them up and cutting them down, first drawing them into the elite inner circle and allowing them to bask in the glow of popularity and acceptance, and then reducing them to positions of dependence and subjugation by turning the group against them. We conclude by discussing the generic features of these inclusionary and exclusionary dynamics, the characteristics of this cyclical pattern, the implications of this socializing experience for the broader societal dynamics of power and manipulation, and the kind of in-group/out-group differentiation that can lead to prejudice and discrimination.
Previous research has demonstrated self-reports of lower levels of four fundamental needs as a result of short periods of face-to-face ostracism, as well as short periods of Internet ostracism (Cyberball), even when the ostracizing others are unseen, unknown, and not-to-be met. In an attempt to reduce the ostracism experience to a level that would no longer be aversive, we (in Study 1) convinced participants that they were playing Cyberball against a computer, yet still found comparable negative impact compared to when the participants thought they were being ostracized by real others. In Study 2, we took this a step further, and additionally manipulated whether the participants were told the computer or humans were scripted (or told) what to do in the game. Once again, even after removing all remnants of sinister attributions, ostracism was similarly aversive. We interpret these results as strong evidence for a very primitive and automatic adaptive sensitivity to even the slightest hint of social exclusion.
Like all perception, social perception reflects evolutionary pressures. In encounters with conspecifics, social animals must determine, immediately, whether the "other" is friend or foe (i.e. intends good or ill) and, then, whether the "other" has the ability to enact those intentions. New data confirm these two universal dimensions of social cognition: warmth and competence. Promoting survival, these dimensions provide fundamental social structural answers about competition and status. People perceived as warm and competent elicit uniformly positive emotions and behavior, whereas those perceived as lacking warmth and competence elicit uniform negativity. People classified as high on one dimension and low on the other elicit predictable, ambivalent affective and behavioral reactions. These universal dimensions explain both interpersonal and intergroup social cognition.
