Did you hear your action? An ecological approach to the senses of ownership and agency.

The Sense of Ownership (SoO) and the Sense of Agency (SoA) are two key components of bodily self-consciousness. In this experiment, we investigated how they are affected by variations in the ecological validity of the moving Rubber Hand Illusion (mRHI) paradigm, which typically include three movement conditions: active congruent, passive congruent, and active incongruent. These conditions were either in a session in which no auditory feedback associated with finger-tapping was eliminated, or in a session in which such a feedback occurred. Since the presence of the auditory feedback more closely corresponds to what individuals experience in daily life when they tap their finger on a surface, sessions with feedback are more ecologically valid, and should thus result in a more marked SoO. Results indicated that in the active movement condition in which the illusion is typically found (congruent), the effect was enhanced when the feedback was present. This advantage emerged on both on objective and subjective measures of SoO. The SoA, on the other hand, is not affected by the auditory feedback.

Justifying atrocities: the effect of moral-disengagement strategies on socially shared retrieval-induced forgetting.

A burgeoning literature has established that exposure to atrocities committed by in-group members triggers moral-disengagement strategies. There is little research, however, on how such moral disengagement affects the degree to which conversations shape people's memories of the atrocities and subsequent justifications for those atrocities. We built on the finding that a speaker's selective recounting of past events can result in retrieval-induced forgetting of related, unretrieved memories for both the speaker and the listener. In the present study, we investigated whether American participants listening to the selective remembering of atrocities committed by American soldiers (in-group condition) or Afghan soldiers (out-group condition) resulted in the retrieval-induced forgetting of unmentioned justifications. Consistent with a motivated-recall account, results showed that the way people's memories are shaped by selective discussions of atrocities depends on group-membership status.

Exposure to Literary Fiction Is Associated With Lower Psychological Essentialism.

We investigated the impact of exposure to literary and popular fiction on psychological essentialism. Exposure to fiction was measured by using the Author Recognition Test, which allows us to separate exposure to authors of literary and popular fiction. Psychological essentialism was assessed by the discreteness subscale of the psychological essentialism scale in Study 1, and by the three subscales of the same scale (such as discreteness, informativeness, and biological basis) in Study 2 that was pre-registered. Results showed that exposure to literary fiction negatively predicts the three subscales. The results emerged controlling for political ideology, a variable that is commonly associated with psychological essentialism, and level of education.

The effect of exposure to fiction on attributional complexity, egocentric bias and accuracy in social perception.

We investigated the effects of long-term exposure to literary and popular fiction on attributional complexity, egocentric bias and accuracy. Results of a pre-registered study showed that exposure to literary fiction is positively associated with scores on the attributional complexity scale. Literary fiction is also associated with accuracy in mentalizing, measured via the Reading the Mind in the Eyes test, and with accuracy in predicting average social attitudes. The predicted negative association between literary fiction and egocentric bias emerged only when education and gender were controlled for-a covariance analysis that was not pre-registered. Exposure to popular fiction is associated solely with attributional complexity, but negatively. We discuss the significance of these findings in the context of the emerging literature regarding the relationship between fiction and social cognition.

Perceiving one's nation: entitativity, agency and security in the international arena.

The perception of groups as real entities rather than mere aggregates of individuals has important consequences on intergroup relations. Social psychological research, in fact, shows that it affects stereotyping, identification process, and intergroup bias. Previous research has also shown that group entitativity is not a positive or negative group attribute per se; rather, it depends on the context and the relationship between the perceiver and the group. While enhancing entitativity leads to worse expectations about the out-group actions, high entitativity is a valued characteristic when associated with an ally or with the in-group. Indeed, enhancing in-group entitativity leads to stronger in-group identification. The specific reasons for why this is the case, however, remain to be ascertained. What is good about in-group entitativity? In the present contribution we propose that in-group entitativity may lead to perceive the group as a real entity provided with intentions and capacity for planned actions, notably ensuring the safety of its members by protecting them against external threats. We report two correlational studies conducted with American citizens (Study 1) and Italian citizens (Study 2), showing that in-group entitativity is associated with a higher level of identification, attribution of intentionality, and perceived security provided by the in-group. These findings were replicated in a third study-conducted with a role-play method on a fictitious scenario-in which entitativity was manipulated rather than measured. Study 3 also shows that artificially increasing the perception of in-group entitativity enhances perceived safety in an international context and reduces the perception of threat from an out-group. Findings are discussed in terms of possible implications for intergroup and international relations.

The attribution of primary and secondary emotions to the in-group and to the out-group: the case of equal status countries.

We examined the attribution of primary and secondary emotions in the context of equal status groups with a non-conflictual relationship, that is, Germans and French. In Study 1 (N = 169), we found that in such an intergroup context, there was no differential attribution of secondary emotions but an over-attribution of primary emotions to the out-group. Only high identifiers tended to attribute more secondary emotions to the in-group than to the out-group. In Study 2 (N = 423), the role of the identification with the in-group and a superordinate group (Europe) in the process of infrahumanization was examined. Participants' national versus European identification was primed. The results did not differ between these two conditions. As in Study 1, an over-attribution of primary emotions to the out-group was observed. Concerning the secondary emotions, the classical infrahumanization effect occurred, that is, an over-attribution of secondary emotions to the in-group.

Panero et al. (2016): Failure to replicate methods caused the failure to replicate results.

Contrary to Kidd and Castano (2013), Panero et al. (2016) fail to find that reading literary fiction improves performance on an advanced test of theory of mind (ToM), the Reading the Mind in the Eyes Test. However, this commentary shows that the findings presented in Panero et al. (2016) are not reliable due to two striking threats to the internal validity of their studies that were not clearly disclosed or discussed in the manuscript or supplementary materials. First, no effective strategy was implemented to ensure that participants read their assigned texts, and examination of the data revealed many participants whose reading times indicate that they were not exposed to the manipulation. Second, further examination shows that two of the largest studies contributing to Panero et al. (2016) are not valid experiments due to a clear failure of random assignment to conditions. These threats to experimental internal validity make the conclusions presented in Panero et al. (2016) untenable. After removing cases in which participants were not exposed to the manipulation and the data from the two studies without random assignment, an analysis reveals that reading literary fiction improves ToM compared to reading popular genre fiction. This result is consistent with prior studies and indicates that a failure to carefully replicate the methods of Kidd and Castano (2013) led to the failure to replicate Kidd and Castano's (2013) results.

What's in a singer's voice: The effect of attachment, emotions and trauma.

Research shows that negative experiences in childhood have a long-lasting impact on one's psychological outcomes and one's physiology. The voice is a crucial means of expression, and its complex physiology is believed to be reflective of emotional and mental states. Parenting practices (particularly those contributing to insecure attachment) and traumatic experiences in childhood may thus also influence vocal characteristics. Except for literature on psychogenic voice disorders, the relationship between such experiences and the 'normal' voice is generally unexplored; we propose that a potential relationship is most likely to emerge in singers, for whom the voice is a more central part of their sense of self. In this paper, we test the hypothesis that vocal characteristics relate to attachment and trauma history. Study 1: 25 singers (age 18-35) completed an attachment history questionnaire (ECR-R) and the Singing Voice Handicap Index. Voice range profile and perturbation measures were recorded and analyzed for voice quality assessment. Study 2: 26 singers (age 19-33) completed the attachment history questionnaire, the Childhood Trauma Questionnaire, and the State and Trait Anxiety Inventory. They were also administered the Test of Self-Conscious Affect to assess shame and guilt proneness. Voice range profile, perturbation, and spectrogram measures were recorded and analyzed. The results indicated that anxious attachment, shame, and emotional neglect can predict vocal acoustic measures of intensity and, to some extent, perturbation. This suggests the need to address attachment, shame, and trauma history patterns in the aspiring performer.

Not quite human: infrahumanization in response to collective responsibility for intergroup killing.

The present research examines how awareness of violence perpetrated against an out-group by one's in-group can intensify the infrahumanization of the out-group, as measured by a reduced tendency to accord uniquely human emotions to out-groups. Across 3 experiments that used different in-groups (humans, British, White Americans) and out-groups (aliens, Australian Aborigines, and Native Americans), when participants were made aware of the in-group's mass killing of the out-group, they infrahumanized the victims more. The perception of collective responsibility, not just the knowledge that the out-group members had died in great numbers, was shown to be necessary for this effect. Infrahumanization also occurred concurrently with increased collective guilt but was unrelated to it. It is proposed that infrahumanization may be a strategy for people to reestablish psychological equanimity when confronted with a self-threatening situation and that such a strategy may occur concomitantly with other strategies, such as providing reparations to the out-group.

On social death: ostracism and the accessibility of death thoughts.

Being rejected, excluded, or simply ignored is a painful experience. Ostracism researchers have shown its powerful negative consequences (Williams, 2007), and sociologists have referred to such experiences as social death (Bauman, 1992). Is this is just a metaphor or does being ostracized make death more salient in people's minds? An experiment was conducted in which participants experienced ostracism or inclusion using the Cyberball manipulation, and the accessibility of death-related thoughts was measured via a word-stem completion puzzle. Results showed enhanced death-thought accessibility in the ostracism condition, as well as a negative effect of dispositional self-esteem on the accessibility of death-related thoughts.

Protecting the ingroup stereotype: ingroup identification and the management of deviant ingroup members.

In two experiments, we investigated the impact of the presentation of a deviant ingroup member on the perception of the ingroup among participants who differed in their degree of identification with the ingroup. In Study 1, we measured psychology students' level of identification with the group of psychologists (i.e. the ingroup) and presented them with an anti-norm versus a pro-norm psychologist. Results showed that in the anti-norm condition (but not in the pre-norm condition), identification predicted the ratings of psychologists as a group and the perception of typicality of the deviant psychologist. Also, in this condition, the impact of the level of identification on the ratings of psychologists proved to be mediated by the perceived typicality of the deviant. In Study 2, group measures were taken both before and after presentation of a deviant among members of an environmentalist group who differed in their level of identification with the ingroup. The level of identification had an impact on the modification of the ratings of environmentalists as a group, and this effect was mediated by the perceived typicality of the deviant environmentalist. The results are discussed in terms of their implications for the black sheep effect and the stereotype change literature.

Reading literary fiction improves theory of mind.

Understanding others' mental states is a crucial skill that enables the complex social relationships that characterize human societies. Yet little research has investigated what fosters this skill, which is known as Theory of Mind (ToM), in adults. We present five experiments showing that reading literary fiction led to better performance on tests of affective ToM (experiments 1 to 5) and cognitive ToM (experiments 4 and 5) compared with reading nonfiction (experiments 1), popular fiction (experiments 2 to 5), or nothing at all (experiments 2 and 5). Specifically, these results show that reading literary fiction temporarily enhances ToM. More broadly, they suggest that ToM may be influenced by engagement with works of art.

Dehumanization, retributive and restorative justice, and aggressive versus diplomatic intergroup conflict resolution strategies.

The desire for justice can escalate or facilitate resolution of intergroup conflicts. Two studies investigated retributive and restorative notions of justice as the mediating factor of the effect of perceived outgroup sentience-an aspect of (mechanistic) dehumanization referring to the emotional depth attributed to others-on intergroup conflict resolution. Study 1 showed that for Palestinians, who see themselves as victims, perceived sentience of Israelis decreased retributive but increased restorative notions of justice, which, ultimately, increased support for conflict resolution by negotiation rather than political violence. Study 2 partially replicated Study 1's findings with Jewish Israelis. The role of perceived sentience and its relationship to retributive and restorative notions of justice in protracted and nonprotracted conflicts and their resolution is discussed.

Ingroup glorification, moral disengagement, and justice in the context of collective violence.

What aspects of ingroup identification can lead people to resist justice for the victims of their ingroup's mistreatment? In three studies carried out in the United States and United Kingdom, in which participants read reports of mistreatment of prisoners and civilians by coalition troops in the Iraq war, ingroup glorification, but not ingroup attachment or other individual-difference variables, was a key predictor of lesser demands for justice, but only when the perpetrators belonged to the ingroup. This effect of glorification was mediated by two moral disengagement mechanisms focusing on the outgroup: minimization of the emotional suffering of the victims' families and explicit dehumanization of the victim group. These findings further reinforce the difference between glorification and other forms of ingroup identification, demonstrating that glorification is problematic in maintaining and fostering intergroup relations because of its connection to moral disengagement.
