Preschoolers' aggression and parent-child conflict: a multiinformant and multimethod study

This multiinformant and multimethod study (N=47) investigated the link between the parent-child relationship system and the display of physical and relational aggression with peers at school during early childhood. Children (mean age=43.54 months, SD=8.02) were observed (80min/child) during free play, and parents and teachers were asked to complete several standard measures. Intercorrelations between aggression subtypes revealed moderate to high levels of correlation for parents and teachers and no significant association for observations of physical and relational aggression. Interinformant agreement was examined, and teachers and parents were found to significantly agree for both physical and relational aggression, and teachers and observers also significantly agreed for both subtypes of aggression. Results of regression analyses suggest that parent-child conflict was uniquely associated with relational aggression among peers when controlling for physical aggression and gender. Ways in which these findings build on the extant literature are discussed.     

Evaluations of relational aggression as a function of relationship type and conflict setting

The present study examined influences on girls' evaluations of relational aggression situations. Second‐, third‐, fifth‐, and sixth‐grade girls evaluated four relational aggression conflict scenarios in terms of attributions of aggressor's intentions, evaluator's behavioral response, evaluator's affective state, and how likely the situation was to actually occur. Girls evaluated intentions of a best friend more positively, reported being more mad at an enemy, and perceived conflict to be more likely to occur with an enemy than a best friend. Aggressor intentions in direct conflict scenarios (aggressor said something mean to evaluator) were perceived as more negative than aggressor intentions in indirect conflict scenarios (aggressor said something mean about evaluator to another peer). Younger girls reported intentions of their enemy as being more positive than did older girls. Further, older girls reported intentions of their best friend as being more positive than intentions of their enemy. Older girls also were more accurate in conceptualizing variations in the conflict setting (direct, indirect) and responding in a context‐consistent manner. Findings are discussed in terms of the social‐relational and social‐situational processes that influence children's evaluations of relational aggression and how the current study extends previous research on relational aggression.

Empathy as a cognitive inhibitor of interpersonal aggression

The studies presented in this paper examined empathy, especially perspective taking, as a potential inhibitor of interpersonal aggression. The theoretical rationale for these investigations derived from Zillmann's [(1988): Aggressive Behavior 14: 51–64] cognitive excitation model. Study 1 revealed that dispositional empathy correlates negatively with self-reported aggression and with conflict responses that reflect little concern for the needs of the other party. Empathy also was positively related to constructive responses to interpersonal conflict (i. e., those that do involve concern for the needs of the other party). In Study 2, perspective taking was manipulated with instructions to subjects prior to participation in a reaction-time task designed to measure aggression. When threat was relatively low, subjects who were instructed to take the perspective of the target responded less aggressively than did those who had been instructed to focus on the task. Study 3 examined the effect of dispositional perspective taking on verbal aggression. Threat was manipulated in terms of the combination of provocation and gender of the interactants. As predicted, perspective taking related to aggression inhibition under conditions of moderate threat–for males under low provocation and females under high provocation. These effects were predicted and explained in the context of the cognitive-excitation model. © 1994 Wiley-Liss, Inc.     

Outline of a denotative definition of aggression

Aggression is defined as generic assertiveness which includes both constructive and destructive behaviors. An attempt is then made to classify the distinctive operational settings (phenotypic situations) which trigger aggression. The classes of such settings are: 1) privation - the frustration of vital needs and the frustration due to inner conflict of needs; 2) conflict (social) - situation-specific competition and intragroup rivalry for dominance; and 3) victimization — predator-prey relations and vandalism per se. Critical questions which emerge from the definition and classification are posed.     

The aggression test as a possible taxonomic tool in the Formica rufa group

The intra- and interspecific aggressive behavior of Formica polyctena, a species of the Formica rufa group, was analyzed and quantified both in the laboratory and in the field. This behavior was used as a potential taxonomic tool for gaining a better understanding of the phyletic relationships among the species within the group. No overt aggression was recorded toward members of the same species. To examine interspecific relationships, F. polyctena was first confronted with F. cunicularia, to ascertain its aggressiveness toward a distantly related species. All such encounters led immediately to overt and prolonged attacks with virtually no initial mutual inspection. This suggests that recognition of strangeness of the unrelated species is almost immediate in F. polyctena, as previously observed in F. lugubris and F. rufa toward the same antagonist. Subsequently, F. polyctena was contrasted with F. lugubris and F. rufa (also belonging to the F. rufa group) in order to compare these related species. Fierce attacks accompanied by all the elements of conflict behavior were observed in all encounters. Moreover, the degree of aggression in the field was higher than in laboratory-paired ants, possibly because of a territorial effect. These data and our previous and similar research indicate that the relationships between F. lugubris and F. rufa are closer than between these two species and F. polyctena. In considering different viewpoints on this problem, the validity of the aggression test is discussed and the opportunity to compare levels of aggressiveness among strictly sympatric samples of red wood ant species gathered from the same ecological environment are considered.     

The aggression test as a taxonomic tool: Evaluation in sympatric and allopatric populations of wood-ant species

Ant-workers of Formica lugubris and F. rufa from colonies living sympatrically (from the same area) and allopatrically (from different areas) were tested in pairs using a laboratory aggression test. The aim was to verify whether sharing the same area of origin influences the relationships among heteroeolonials between and within these species which belong to the F. rufa group. The results suggest that a similar degree of agonistic behaviour (ritualised aggression) was shown in sympatric and allopatric conspecific dyads of both species studied. The interactions between F. lugubris and F. rufa were characterised by a low level of overt aggression both in sympatric and allopatric pairs, confirming the interspecific tolerance observed in our previous studies on these wood-ant species. This reduced aggressiveness between workers of F. lugubris and F. rufa coming from the same or a different area can be interpreted on the basis of their sharing common signals, such as odours and patterns of behaviour. Therefore, their mutual tolerance and acceptance can be indicative of a phylogenetic closeness between such species. We propose that an aggression test can be a valid tool for elucidating systematic problems in this taxonomically difficult group of ants. © 1993 Wiley-Liss, Inc.     

Disappointment expression evokes collective guilt and collective action in intergroup conflict: the moderating role of legitimacy perceptions

Research on intergroup emotions has largely focused on the experience of emotions and surprisingly little attention has been given to the expression of emotions. Drawing on the social-functional approach to emotions, we argue that in the context of intergroup conflicts, outgroup members’ expression of disappointment with one’s ingroup induces the complementary emotion of collective guilt and correspondingly a collective action protesting ingroup actions against the outgroup. In Study 1 conducted immediately after the 2014 Gaza war, Jewish-Israeli participants received information about outgroup’s (Palestinians) expression of emotions (disappointment, fear, or none). As predicted, outgroup’s expression of disappointment increased collective guilt and willingness to participate in collective action, but only among those who saw the intergroup situation as illegitimate. Moreover, collective guilt mediated the relationship between disappointment expression and collective action, moderated, again, by legitimacy perception. In Study 2, we replicated these results in the context of racial tension between Black and White Americans in the US. We discuss the theoretical and applied implications of the findings.     

Ethics of aggression research: Papers from a symposium of International Society for Research on Aggression

Three papers are presented from the first symposium on ethical issues in aggression research of the International Society for Research on Aggression held at the biennial meetings 1980 in Haren, The Netherlands. The symposium reflected a growing awareness of the Society that their research is a matter for public concern and scrutiny, both for its potentially good uses, and for its potential misuse and misinterpretation. A paper by Santiago Genovés, a Mexican anthropologist, outlined some of the issues concerning the dissemination of information and misinformation of aggression to the public, along with an extensive bibliography on the subject. A paper by Paul Brain, a British zoologist, addressed the issues surrounding the use of animals in aggression research and the arguments being used in public attacks upon it. Daniel Wikler, a practitioner of normative ethics from the United States, discussed ethics as theory and as practice and suggested some of the types of actions that the Society could consider undertaking.     

The effects of viewing physical and relational aggression in the media: Evidence for a cross-over effect

Research has shown that viewing violence in the media can have a profound impact on aggressive thoughts and behaviors. However, the impact of viewing relational aggression in the media has rarely been examined. This paper presents the results of an experimental study that examines the impact of viewing relational and physical aggression in the media on subsequent aggression. In this study, adult females were shown video clips containing no-aggression, relational aggression, or physical aggression. Their aggressive behavior was measured through the use of a competitive reaction time task (physical aggression) and evaluations of a confederate of the experiment (relational aggression). As a whole, participants viewing either relational or physical aggression behaved similarly. Specifically, participants who viewed either type of aggression were subsequently more physically and relationally aggressive than those who viewed the non-aggressive clip. The results show evidence for a generalization effect of viewing media aggression, in that viewing one form of aggression can influence the manifestation of other forms. This is the first study to show that viewing relational aggression in the media can increase subsequent physical aggression. Implications for parents, media producers, and policy makers are discussed.     

Illuminating the nomological network of digital aggression: Results from two studies

We examined the nomological network surrounding digital aggression (DA), in regards to other forms of aggression/antisocial behavior and individual difference variables commonly associated with other forms of aggression/antisocial behavior. Two large samples of university students (N = 713 and 633, respectively) completed a series of questionnaires and in some cases, an additional experience sampling study. Results revealed that, in emerging adulthood, DA appears to have a unique demographic profile relative to the other forms of aggression and antisocial behavior. Results further suggested that, when examined simultaneously, only social aggression and non‐aggressive rule‐breaking evidenced independent associations with DA. These associations persisted even in the absence of social media use. Unique associations with most individual difference variables dissipated once we controlled for social aggression and rule‐breaking, although DA was independently associated with extraversion and alcohol use problems. Such findings begin to embed DA in its broader nomological network and suggest clear functional links with both social aggression and non‐aggressive rule‐breaking.

     

When the needs for affiliation and intimacy are frustrated: Envy and indirect aggression among German and Cameroonian adults

This article tests the hypothesis that a lack of experiences of relatedness is linked to negative outcomes such as envy and indirect aggression in particular if individuals are characterized by a high implicit affiliation-intimacy motive. Assumptions were examined in a sample of 273 adults from Germany and Cameroon. Components of the affiliation-intimacy motive, i.e., needs for affiliation and intimacy, were assessed with a picture story exercise. Additionally, participants reported on experiences of relatedness, indirect aggression, and envy. Low experiences of relatedness are associated with enhanced levels of envy and indirect aggression among individuals with a pronounced implicit affiliation-intimacy motive. Those effects hold true across cultural groups. Findings point to the prominent role of the implicit affiliation-intimacy motive for interpersonal emotions and behavior.     

Conspecific aggression influences food carrying: Studies on a wild population of Rattus norvegicus

Laboratory rats, like many other animal species, transport food. Their behavior is influenced by factors such as food size, the time required to eat, travel distance, travel difficulty, and the availability of cover, etc. Recent versions of optimal foraging theory suggest that species that display such behavioral patterns do so in order to minimize risk to predation while at the same time maximizing food gain. Nevertheless, it is not clear that this explanation applies to rats, nor is it easy to investigate this problem in a laboratory. The results of the present study on urban feral rats show that their food handling behavior is similar to that of domestic rats. The results also suggest that food carrying can serve defensive as well as communicative functions. Aggression around food sources was high. Smaller rats always carried food and some large rats infrequently carried food, suggesting that the food carrying by smaller, subordinate rats may help them avoid conspecific aggression. The rats also vigorously attempted to steal food that was carried home by conspecifics. This result suggests that food carrying can redistribute food resources and inform conspecifics about food availability. The results demonstrate the utility of multilevel behavioral analysis and also demonstrate that for rats, food transport has functions other than predator avoidance, including avoidance of conspecific aggression and communication about food availability. © 1996 Wiley-Liss, Inc.     

Instigation to aggress and escalation of aggression examined from a personological perspective: The role of irritability and of emotional susceptibility

Two studies were conducted using Buss hostility machine paradigm to investigate the role of individual differences in irritability and emotional susceptibility on the instigation to aggress by a self-esteem lowering manipulation and on the hypothesized escalation of aggression over trials. The role of sex was also examined. In the first study, 60 highly irritable and 60 low irritable subjects were given the opportunity to deliver electric shocks to an experimental confederate, half after being provoked by a negative judgement on their performance in a learning task, half without such an experience. Each group of subjects was divided equally between males and females. It was found that highly irritable subjects, both males and females, delivered higher shocks after provocation than low irritable subjects under similar circumstances. An upward drift of shock level over trials was found only in provoked males and only in highly irritable females. In the second study, 60 highly emotionally susceptible and 60 low emotionally susceptible males and females were given the opportunity to deliver electric shocks to an experimental confederate, half after experiencing provocation, half without such an experience. It was found that provoked subjects delivered higher shocks than unprovoked subjects and that highly emotionally susceptible subjects delivered higher shocks than low emotionally susceptible subjects. Whereas an upward drift of shock levels over trials was found only in provoked males, the same effect was found in females, whether provoked or not. These findings are discussed in terms of the importance of stable personality characteristics that may mediate aggressive response.     

When flexibility helps: Another look at the availability of flexible work arrangements and work-family conflict

Despite the positive press given to flexible work arrangements (FWA), empirical research investigating the link between the availability of these policies and work-family conflict is largely equivocal. The purpose of the present study was to begin to reconcile these mixed results through more precise measurement and the examination of moderators. Using a sample of employed women, we found that FWA relate more highly to work interference with family (WIF) than to family interference with work (FIW) and that temporal flexibility (flextime) has a stronger relationship with WIF than does spatial flexibility (flexplace). Additionally, we found family responsibility significantly moderated these relationships, such that the relationship was stronger for those with greater family responsibility. Practical and theoretical implications are discussed.     

Tackling conflict: a beyond opposites approach

The issue of conflict is pervasive to most human undertakings at both individual/intra level and group level. Conflicts are the source of internal and external suffering. It has been argued by many authors that although humans have advanced in the technological sphere tremendously and managed to find solutions to countless scientific and material challenges, their ability to effectively resolve internal and external aspects of conflicts remains elusive. Given the level of pain and suffering that can derive from both psychological and social conflicts, it can be argued that any advances in helping improve the resolution of conflicts can have immense benefits in alleviating human suffering making this issue a very worthwhile area of study. Accordingly this paper aims to describe a developing counselling methodology for addressing conflict. The methodology, which was originally inspired by Fuzzy Logic, adopts a cognitive behavioural therapy (CBT) perspective despite awareness of its limitations. The paper traces the origins of the methodology and the areas within counselling it could be applied to. The paper concludes with recommendations regarding the relevance of this approach to an increasingly multicultural environment.     

Aversive potency of urine from dominant and subordinate male laboratory mice (Mus musculus): Resolution of a conflict

The present study assessed the aversive potency of urine collected from male albino mice that had been clearly identified as dominants/winners or subordinates/losers of paired aggression tests and then housed either individually or in a quasi-paired situation in which only a wire-mesh divider separated the two mice. This divider permitted constant visual, olfactory, auditory, and some tactile contact. The responses of individually tested, group-housed males were recorded when half of the substrate in a test box was treated with either water or one of the four urine types; the other half remained untreated. Significant preferences for the untreated half were found when the urine of winners or losers housed in individual metabolism cages or that of pair-housed dominants was used as the test stimulus. On the other hand, neither water nor the urine of cohabiting subordinate males was avoided. The present findings confirmed our earlier reports that the urine of dominant male mice was aversive, whereas that of their cohabiting subordinate partners was not. They also identified Sawyer's [1978] procedure of housing winners and losers in individual cages, with the consequent interruption of social contact as the likely reason for his failure to replicate our reports that subordinate male urine lacked aversive properties. The territorial implications of the aversive factor and other urinary signals are discussed.     

Exposure to violent video games and aggression in German adolescents: a longitudinal analysis

The relationship between exposure to violent electronic games and aggressive cognitions and behavior was examined in a longitudinal study. A total of 295 German adolescents completed the measures of violent video game usage, endorsement of aggressive norms, hostile attribution bias, and physical as well as indirect/relational aggression cross‐sectionally, and a subsample of N=143 was measured again 30 months later. Cross‐sectional results at T1 showed a direct relationship between violent game usage and aggressive norms, and an indirect link to hostile attribution bias through aggressive norms. In combination, exposure to game violence, normative beliefs, and hostile attribution bias predicted physical and indirect/relational aggression. Longitudinal analyses using path analysis showed that violence exposure at T1 predicted physical (but not indirect/relational) aggression 30 months later, whereas aggression at T1 was unrelated to later video game use. Exposure to violent games at T1 influenced physical (but not indirect/relational) aggression at T2 via an increase of aggressive norms and hostile attribution bias. The findings are discussed in relation to social‐cognitive explanations of long‐term effects of media violence on aggression. Aggr. Behav. 35:75–89, 2009. © 2008 Wiley‐Liss, Inc.     

Maternal aggression in mice: Protection of young is a by-product of attacks at the home site

Lactating female mice attacked male intruders in their home cages but showed little attack behavior either in novel cages or in cages with which they had been familiarized. Presence or absence of young did not determine the occurrence of maternal aggression, whereas attacks on the young by the intruder decreased maternal aggression and increased cannibalism of pups by the dams. Apparently, if the function of maternal aggression in mice is protection of the young, such protection occurs because the pups are in a place where attacks are likely to occur and not because the dam “defends” the young.
