Generically partisan: Polarization in political communication.

American political parties continue to grow more polarized, but the extent of ideological polarization among the public is much less than the extent of perceived polarization (what the ideological gap is believed to be). Perceived polarization is concerning because of its link to interparty hostility, but it remains unclear what drives this phenomenon. We propose that a tendency for individuals to form broad generalizations about groups on the basis of inconsistent evidence may be partly responsible. We study this tendency by measuring the interpretation, endorsement, and recall of category-referring statements, also known as generics (e.g., "Democrats favor affirmative action"). In study 1 (n = 417), perceived polarization was substantially greater than actual polarization. Further, participants endorsed generics as long as they were true more often of the target party (e.g., Democrats favor affirmative action) than of the opposing party (e.g., Republicans favor affirmative action), even when they believed such statements to be true for well below 50% of the relevant party. Study 2 (n = 928) found that upon receiving information from political elites, people tended to recall these statements as generic, regardless of whether the original statement was generic or not. Study 3 (n = 422) found that generic statements regarding new political information led to polarized judgments and did so more than nongeneric statements. Altogether, the data indicate a tendency toward holding mental representations of political claims that exaggerate party differences. These findings suggest that the use of generic language, common in everyday speech, enables inferential errors that exacerbate perceived polarization.

Hostile Attribution Bias Shapes Neural Synchrony in the Left Ventromedial Prefrontal Cortex during Ambiguous Social Narratives.

Hostile attribution bias refers to the tendency to interpret social situations as intentionally hostile. While previous research has focused on its developmental origins and behavioral consequences, the underlying neural mechanisms remain underexplored. Here, we employed functional near-infrared spectroscopy (fNIRS) to investigate the neural correlates of hostile attribution bias. While undergoing fNIRS, male and female participants listened to and provided attribution ratings for 21 hypothetical scenarios where a character's actions resulted in a negative outcome for the listener. Ratings of hostile intentions were averaged to measure hostile attribution bias. Using intersubject representational similarity analysis, we found that participants with similar levels of hostile attribution bias exhibited higher levels of neural synchrony during narrative listening, suggesting shared interpretations of the scenarios. This effect was localized to the left ventromedial prefrontal cortex (VMPFC) and was particularly prominent in scenarios where the character's intentions were highly ambiguous. We then grouped participants into high and low bias groups based on a median split of their hostile attribution bias scores. A similarity-based classifier trained on the neural data classified participants as having high or low bias with 75% accuracy, indicating that the neural time courses during narrative listening was systematically different between the two groups. Furthermore, hostile attribution bias correlated negatively with attributional complexity, a measure of one's tendency to consider multifaceted causes when explaining behavior. Our study sheds light on the neural mechanisms underlying hostile attribution bias and highlights the potential of using fNIRS to develop nonintrusive and cost-effective neural markers of this sociocognitive bias.

Fighting force and experience combine to determine contest success in a warlike mammal.

Conflicts between social groups or "intergroup contests" are proposed to play a major role in the evolution of cooperation and social organization in humans and some nonhuman animal societies. In humans, success in warfare and other collective conflicts depends on both fighting group size and the presence and actions of key individuals, such as leaders or talismanic warriors. Understanding the determinants of intergroup contest success in other warlike animals may help to reveal the role of these contests in social evolution. Using 19 y of data on intergroup encounters in a particularly violent social mammal, the banded mongoose (Mungos mungo), we show that two factors, the number of adult males and the age of the oldest male (the "senior" male), have the strongest impacts on the probability of group victory. The advantage conferred by senior males appears to stem from their fighting experience. However, the galvanizing effect of senior males declines as they grow old until, at very advanced ages, senior males become a liability rather than an asset and can be evicted. As in human conflict, strength in numbers and the experience of key individuals combine to determine intergroup contest success in this animal society. We discuss how selection arising from intergroup contests may explain a suite of features of individual life history and social organization, including male eviction, sex-assortative alloparental care, and adult sex ratio.

Characterization of Pan social systems reveals in-group/out-group distinction and out-group tolerance in bonobos.

Human between-group interactions are highly variable, ranging from violent to tolerant and affiliative. Tolerance between groups is linked to our unique capacity for large-scale cooperation and cumulative culture, but its evolutionary origins are understudied. In chimpanzees, one of our closest living relatives, predominantly hostile between-group interactions impede cooperation and information flow across groups. In contrast, in our other closest living relative, the bonobo, tolerant between-group associations are observed. However, as these associations can be frequent and prolonged and involve social interactions that mirror those within groups, it is unclear whether these bonobos really do belong to separate groups. Alternatively, the bonobo grouping patterns may be homologous to observations from the large Ngogo chimpanzee community, where individuals form within-group neighborhoods despite sharing the same membership in the larger group. To characterize bonobo grouping patterns, we compare the social structure of the Kokolopori bonobos with the chimpanzee group of Ngogo. Using cluster analysis, we find temporally stable clusters only in bonobos. Despite the large spatial overlap and frequent interactions between the bonobo clusters, we identified significant association preference within but not between clusters and a unique space use of each cluster. Although bonobo associations are flexible (i.e., fission-fusion dynamics), cluster membership predicted the bonobo fission compositions and the spatial cohesion of individuals during encounters. These findings suggest the presence of a social system that combines clear in-group/out-group distinction and out-group tolerance in bonobos, offering a unique referential model for the evolution of tolerant between-group interactions in humans.

Interparental conflict dimensions and children's psychological problems: Emotion recognition as a mediator.

This study tested children's emotion recognition as a mediator of associations between their exposure to hostile and cooperative interparental conflict and their internalizing and externalizing symptoms. From 2018 to 2022, 238 mothers, their partners, and preschool children (Mage = 4.38, 52% female; 68% White; 18% Black; 14% Multiracial or another race; and 16% Latinx) participated in three annual measurement occasions. Path analyses indicated that Wave 1 observations of hostile interparental conflict predicted residualized increases in children's emotion recognition accuracy (i.e., angry, sad, and happy) at Wave 2 (ß = .27). Wave 2 emotion recognition, in turn, predicted residualized decreases in children's internalizing symptoms at Wave 3 (ß = -.22). Mediational findings were partly attributable to children's accuracy in identifying angry and high-intensity expressions.

Hostile attributional biases in severe alcohol use disorder: replication, gender specificity, and mechanistic insights.

AIMS: Despite their importance in the emergence and persistence of severe alcohol use disorder (SAUD), social cognition impairments remain understudied in this population. Hostile attributional biases (HAB), a key component of social cognition, may be involved in interpersonal problems and SAUD maintenance. However, current evidence for HAB in SAUD is highly preliminary, as it relies on a single study based on a small sample and on a task that cannot dissociate increased hostile from reduced benign attributions. We therefore used an improved methodology to further characterize this bias and disentangle underlying mechanisms. In addition, we explored potential gender differences. METHOD: A total of 56 patients (28 women) diagnosed with SAUD and 66 (27 women) demographically matched controls completed the Word-Sentence Association Paradigm-Hostility, which provides a valid, spontaneous, and relatively implicit assessment of both hostile and benign social attributions related to ambiguous situations. They also completed self-report measures of psychopathology and interpersonal problems. RESULTS: At the group-level, patients with SAUD presented higher HAB than controls, without group differences for benign attributions. Gender analyses revealed that this effect selectively emerged in men with SAUD. Further, patients' benign attributions did not differ from their hostile attributions. Finally, HAB (not benign attributions) were associated with interpersonal problems and state anxiety in patients. CONCLUSIONS: The association between SAUD and HAB at the group level is genuine and replicable across samples and tasks. This association may further selectively emerge in men. Our results also confirm the functional significance of HAB in SAUD, and point to potential mechanisms and clinical recommendations.

Aggression by omission: Redefining and measuring an understudied construct.

Researchers of aggression have classically focused on what has been previously called active aggression-the deliberate infliction of harm through the direct application of deleterious consequences. However, the counterpart to this, what was originally called passive aggression, has gone understudied, and its definition has mutated beyond its original conceptualization. The present two studies (N's 196 and 220, respectively) attempted to examine passive aggression as originally defined-the deliberate withholding of behavior to ensure that a target is harmed-and renaming it aggression by omission (ABO), in contrast to aggression by commission (ABC). These studies found that both fit within a similar nomological network of antagonism, Sadism, and trait aggression. Study 2 additionally found that both were equally affected by provocation and were considered equally harmful. These findings encourage further research into ABO to capture this construct concretely, especially in the context of common paradigms (e.g., the Taylor Aggression Paradigm, Hot Sauce, Point-Subtraction Aggression Paradigm), and trait aggression scales, which typically measure ABC.

Daily aggression domains differentially relate to daily affect and self-esteem.

How do daily fluctuations in aggression relate to daily variability in affect and self-esteem? Although research has examined how trait aggression relates to affect and self-esteem, state aggression has received little attention. To this end, we had 120 US undergraduates participate in a 14-day daily diary study where they responded to state-level measures of aggression, affect, and self-esteem. Crucially, we used multifaceted state measures of both aggression (anger, hostility, verbal aggression, physical aggression) and affect (positive vs. negative, activated vs. deactivated). Multilevel models revealed that daily anger and hostility related positively to daily negative affect and negatively to daily positive affect. Similarly, daily anger and hostility related negatively to daily self-esteem. In contrast, daily verbal and physical aggression were largely unrelated to daily affect and self-esteem; however, unexpectedly, daily physical aggression related positively to daily positive activated affect, but only when controlling for the other daily aggression domains. Overall, daily attitudinal aggression measures-anger and hostility-related to daily affect and self-esteem in theoretically consistent ways, whereas daily behavioral aggression measures-verbal and physical aggression-did not. Our findings support expanding the General Aggression Model to incorporate state-level processes.

Understanding the moral cognition of aggression: Longitudinal serial effects of personal relative deprivation and hostility on within-person changes in civic moral disengagement.

Moral disengagement is an important aggressive and moral cognition. The mechanisms of changes in moral disengagement remain unclear, especially at the within-person level. We attempted to clarify this by exploring the serial effects of personal relative deprivation and hostility on civic moral disengagement. We conducted a three-wave longitudinal survey with 1058 undergraduates (63.61% women; mean age = 20.97). The results of the random intercept cross-lagged panel model showed that personal relative deprivation at Wave 1 and hostility at Wave 2 formed a serial effect on the within-person changes in civic moral disengagement at Wave 3, and the longitudinal indirect effect test showed that the within-person dynamics in hostility at Wave 2 acted as a mediator. The results of multiple group analysis across genders further showed that the longitudinal indirect role of hostility at Wave 2 was only observed for men, but not for women, which indicates the moderating effect of gender. These findings facilitate an understanding of the mechanisms of aggressive cognitions at the within-person level and offer implications for the prevention and intervention of aggression from the perspective of moral cognition.

Aggressiveness, inhibitory control, and emotional states: A provocation paradigm.

The current study examines the effects of trait aggressiveness, inhibitory control and emotional states on aggressive behavior in a laboratory paradigm. One hundred and fifty-one adult participants took part (73 men, 71 women, and 7 nondisclosed). Event Related Potentials (ERPs) during a Go/No-Go task were utilized to capture the extent of inhibitory processing, with a laboratory provocation paradigm used to assess aggression. Contrary to the expectations, negative affective responses to provocation were negatively associated only with short-lived aggression and only among those with high past aggressiveness. Furthermore, past aggressiveness was related to a continuous increase in laboratory aggressive behavior regardless of the level of inhibitory control (P3 difference amplitude). However, feeling hostile was associated with short-lived aggressive behavior, only in those with lower levels of inhibitory control. These findings demonstrate the effect of distinct mechanisms on different patterns of aggressive behavior.

Violent and prosocial music: Evidence for the impact of lyrics and musical tone on aggressive thoughts, feelings, and behaviors.

Although there is a large research base on the psychological impacts of violent and prosocial visual media, there is little research addressing the impacts of violent and prosocial music, and which facets of the music have the greatest impact. Four experiments tested the impact of lyrics and/or musical tone on aggressive and prosocial behavior, and on underlying psychological processes, using purpose-built songs to avoid the effect of music-related confounds. In study one, where mildly aggressive, overtly aggressive and violent lyrics were compared to neutral lyrics, any level of lyrical aggression caused an increase in behavioral aggression, which plateaued for all three aggression conditions. Violent lyrics were better recalled than other lyrics one week later. In studies two-three no significant effects of lyrics, or of aggressive versus nonaggressive musical tone, were found on aggressive or prosocial behavior. In terms of internal states, violent lyrics increased hostility/hostile cognitions in all studies, and negatively impacted affective state in three studies. Prosocial lyrics decreased hostility/hostile cognitions in three studies, but always in tandem with another factor. Aggressive musical tone increased physiological arousal in two studies and increased negative affect in one. In study four those who listened to violent lyrics drove more aggressively on a simulated drive that included triggers for aggression. Overall, violent lyrics consistently elicited hostility/hostile cognitions and negative affect, but these did not always translate to aggressive behavior. Violent music seems more likely to elicit behavioral aggression when there are aggression triggers and a clear way to aggress. Implications are discussed.

Exposure to aggression in three contexts of emergency response: A longitudinal examination of the relationship with psychological characteristics of the emergency responder.

Some emergency responders are more often exposed to workplace aggression than others. Victimological theories and previous studies suggest that characteristics of the target may predict exposure to workplace aggression. This paper examines the relationship between negative affect, hostile attribution, dominance, empathy, self-evaluations, and exposure to workplace aggression among emergency responders. Emergency medical workers, firefighters and police officers in the Netherlands filled in a survey during three measurement occasions (6 months apart). Results from the three occupational groups were presented separately. Results suggest that some psychological characteristics are related to exposure to workplace aggression, but that the contribution of these characteristics in the explanation of exposure to workplace aggression is limited. In addition, although differences between occupational groups could not be statistically tested due to differences in the factor structure of exposure to workplace aggression between the three groups of emergency response, differences seem to occur in models between emergency response contexts. Implications and suggestions for future research are discussed.

Visual psychosocial profiling of Chinese temporomandibular disorder pain patients and correlations with somatosensory function.

BACKGROUND: Psychosocial function of Chinese temporomandibular disorders (TMD) pain patients and the correlation with somatosensory function has not been sufficiently studied. OBJECTIVE: The study aims at assessing the psychosocial function of Chinese TMD pain patients by visualisation method and evaluating the correlations with somatosensory function quantitatively. METHODS: The Symptom Checklist 90 (SCL-90) questionnaire and standardised quantitative sensory testing (QST) were administered to 70 Chinese TMD pain patients and age- and gender-matched healthy controls (HCs). Of these, 40 TMD arthralgia patients received QST before and after medication. Psychosocial and somatosensory parameters were transformed into standardised scores. Differences within groups were assessed through t tests. Correlations between psychosocial and somatosensory profiles were explored through correlation analyses with Bonferroni correction for multiple comparisons. RESULTS: 100% of the Chinese TMD pain patients exhibited psychosocial distress in contrast to HCs. Anger and hostility showed negative correlation with the thermal nonnociceptive parameter (thermal sensory limen, p =.002) and nociceptive parameters (cold pain threshold and pain pressure threshold, p<.001). Correlation analysis indicated that cold detection threshold was negatively correlated with somatization and mechanical pain sensitivity had a negative correlation with anger and hostility through medical treatment (p <.001). CONCLUSIONS: Visual psychosocial profiles provided an easy overview of psychosocial function in Chinese TMD pain patients. Anger and hostility was associated with increased thermal nonnociceptive and nociceptive sensitivity to stimuli. Psychosocial distress might be negatively associated with TMD treatment response which indicated a possible need for psychological intervention during treatment.

The inner workings of anger: A network analysis of anger and emotion regulation.

OBJECTIVE: This study aimed to investigate the interrelations between emotion regulation strategies and different types of anger using network analysis. METHOD: Data were drawn from a cross-sectional sample of 538 adults (55% females; mean age = 39.8 years, SD = 12.3) seeking treatment for anger. Data were collected between March and November 2019 in Sweden. Participants completed measures of anger problems (anger expression, anger suppression, angry reactions, anger rumination, trait anger, hostility, physical aggression, and verbal aggression) and emotion regulation (cognitive reappraisal, expressive suppression, anger relaxation, and five mindfulness strategies). To determine whether distinct clusters of anger nodes would emerge, exploratory graph analysis was employed. Based on clustering of nodes, we estimated separate networks including all measures of emotion regulation. RESULTS: Two clusters emerged: one consisting primarily of cognitive components of anger, and another of behavioral. Across networks, anger nodes were strongly interconnected, and anger rumination and anger suppression were especially influential. Several direct links were found between specific emotion regulation strategies and cognitive components of anger, whereas most strategies were only indirectly related to angry behavior. Cognitive reappraisal showed no direct link with any of the anger nodes. CONCLUSIONS: Our findings reveal potential pathways by which different emotion regulation strategies may influence different types of anger, which could serve as therapeutic targets.

Rearrest is associated with heightened callous-unemotional traits: No moderating effect of maternal relationship quality.

OBJECTIVE: The presence of callous-unemotional (CU) traits in adolescence predisposes youth to negative behavioral and social outcomes and may be particularly damaging to youth involved in the justice system. Whereas research has shown that CU traits predict later arrest, it remains unknown whether rearrest predicts changes in CU traits and whether these associations may be modified by maternal relationship quality. The present study assessed whether being rearrested predicted changes in CU traits and whether these associations varied by maternal warmth and maternal hostility. HYPOTHESES: We hypothesized that self-reported CU traits would increase at data collection time points following rearrest. Further, we hypothesized that maternal warmth would buffer the negative effects of rearrest, whereas maternal hostility would not have a significant moderating effect on the associations. METHOD: Hypotheses were tested using a large, multisite longitudinal data set of 1,216 justice-involved male youth (Mage = 15.82 years at baseline; 47% Latino, 38% Black/African American, 15% White). Data from a series of nine interviews (across a 7-year period) were used to determine associations between rearrest at one-time point and CU traits at the subsequent time point. RESULTS: Rearrest is associated with a significant increase in CU traits. However, these associations are not moderated by either maternal warmth or maternal hostility. CONCLUSIONS: Rearrest predicts increases in a known risk factor for healthy socioemotional development among justice-involved youths (CU traits). Moreover, the way rearrest is associated with CU traits does not change depending on maternal warmth; rearrest is associated with increases in CU traits irrespective of the quality of a youth's relationship with their mother.

Longitudinal Associations Between Interpersonal Distrust and Social Aggression During College: Disentangling the Within-Person Process from Stable Between-Person Differences.

There is a dearth of information on the relationship between interpersonal distrust and social aggression in the youth, although both may lead to negative interpersonal relationships. Furthermore, scholars have not explored whether interpersonal distrust influences later social aggression over time at the within-person level. This study used five wave longitudinal data to investigate the longitudinal association between interpersonal distrust and social aggression and the role of hostile attribution bias in this relationship; notably, it used a relatively rigorous approach-the random intercept cross-lagged panel model-to disentangle within-person processes from stable between-person differences. The final number of participants included 1053 undergraduate students (677 female students and 376 male students), and 64.3% were female students, with a mean age of 18.45 years (SD = 0.95) at first measurement. Participants completed assessments for interpersonal distrust, hostile attribution bias, and social aggression at five time points across 6-month intervals. At the within-person level, the results revealed that interpersonal distrust was a predictor of later social aggression and that hostile attribution bias acted as a longitudinal mediator in this relationship. This result indicates that to enhance interpersonal harmony and reduce individual hostility and aggression toward others, intervention programs should aim to reduce interpersonal distrust.

Direct and Indirect Longitudinal Associations of Mother and Father Engagement in Middle Childhood on Adolescent Externalizing and Internalizing Behaviors.

Parent engagement is an important aspect of parenting during childhood. However, little is known about the unique longitudinal associations of mother and father engagement with adolescents' externalizing and internalizing problem behaviors. This study uses Future of Families and Child Wellbeing Study data to examine the potential direct and indirect associations of parent engagement at age 9 on adolescent externalizing and internalizing behaviors at age 15. The analytic sample size is 1349, and at age 9, the mean age of children was 9.40 years (SD = 0.37). Forty-eight percent of children were female and 68% of them were from the married families. The results show that while controlling for mother engagement, higher father engagement at age 9 was directly associated with fewer adolescent internalizing behaviors, only among adolescent boys and in married families. In addition, among adolescent boys, father engagement had an indirect association with externalizing behaviors through father-child closeness. Mother engagement, however, is only found to have an indirect association with adolescents' externalizing and internalizing behaviors through maternal hostility (while controlling for father engagement). The results for mother engagement held for boys and in married families only. The findings indicate that both mother and father engagement during childhood is important and helpful to prevent adolescent problem behaviors directly or indirectly via parent-child relationship.

Two Islamophobias? Racism and religion as distinct but mutually supportive dimensions of anti-Muslim prejudice.

Debates about Islamophobia have been blighted by the question of whether the prejudice can be defined as a form of racism or as hostility to religion (or a combination of the two). This paper sheds light on this debate by presenting the findings of a new nationally representative survey, focused on the UK, that contrasts perceptions of Muslims not only with perceptions of other ethnic and religious minorities but also with perceptions of Islam as a religious tradition. We find that prejudice against Muslims is higher than for any other group examined other than Travellers. We also find contrasting demographic drivers of prejudice towards Muslims and towards Islam. Across most prejudice measures we analyse, intolerant views are generally significantly associated with being male, voting Conservative and being older, although not with Anglican identity. We find, however, that class effects vary depending on the question's focus. Anti-immigration sentiment - including support for a 'Muslim ban' - is significantly correlated with being working-class. However, prejudice towards Islam as a body of teachings (tested using a question measuring perceptions of religious literalism) is significantly correlated with being middle-class, as is negative sentiment towards Travellers. Using these findings, the paper makes an argument for supplementing recent scholarship on the associations between racism and Islamophobia with analyses focusing on misperceptions of belief.

Trait Hostility Moderates the Relationships Between Work Environments and Ambulatory Blood Pressure and Momentary Affect.

OBJECTIVE: Hostility is a risk factor for cardiovascular disease and mortality, but less is known about when hostility poses greatest risk. Work environments can be characterized by features that are reactive for high-hostile individuals. Using a person by environment approach, this article tested whether hostility interacted with work location to predict the cardiovascular disease risk factors of ambulatory blood pressure (ABP) and momentary affect. METHOD: Community participants ( n = 108; age, 20-68 years; mean [standard deviation] = 36.52 [11.96] years; 66.06% men; primarily 35.62% non-Hispanic Black, 31.51% non-Hispanic White, and 15.07% Latino/Hispanic) completed a measure of trait hostility followed by two 24-hour ABP monitoring sessions. After each ABP reading, ecological momentary assessment was used to capture participants' current location and ratings of anger, sadness, happiness, and anxiety. RESULTS: A total of 4321 observations were recorded. Multilevel models tested the relationship between work location, trait hostility, and their interaction on ABP and momentary affect. Participants higher on hostility had higher systolic ABP, diastolic ABP, anger, and sadness (but not happiness or anxiety) when at work compared with when not at work; no differences were observed for those lower on hostility. A more consistent pattern of results was found for the William hostility subscale than a traditional measure. CONCLUSIONS: Results suggest that mechanisms for how trait hostility can lead to cardiovascular disease and mortality and highlight the importance of studying traits like hostility within context. Future research should consider the role of social determinates of health like socioeconomic status and features of the work environment to better understand this relationship.

Emotion regulation mediates the effects of sleep on stress and aggression.

It is well established that poor sleep directly increases stress and aggression, but potential mediators of this relationship remain poorly understood. The present study provided the first direct test of whether capacity for emotion regulation mediated the relationship between sleep with stress. It also aimed to extend current understanding of whether emotion regulation might mediate the association between sleep and aggression, by assessing four distinct subcomponents of aggression (anger, hostility, verbal aggression, and physical aggression). In service of these goals, 740 participants completed validated measures of sleep, stress, aggression, and emotion regulation. Results showed that emotion regulation partially mediated the relationship between sleep quality with stress, anger, hostility, and verbal aggression, and fully mediated the relationship between sleep with physical aggression. These data provide novel evidence that emotion regulation abilities may serve as a protective factor against the negative consequences of sleep disturbances.
