One of the main purposes of the present study was to use a parental punitiveness scale, that was developed on the assumption that parental punitiveness is a function of the situation in which aggression takes place. This in turn was used to determine what relationship a child's perception of parental discipline toward aggression has to varying degrees of church attendance of the child.

Men commit the majority of violent crime, yet the majority of men do not commit violent crime. Why is this? Research connecting men and violence cannot fully explain this phenomenon, namely, the variation among men regarding violence. This research study seeks to empirically measure masculinity and to study its relationship to perceptions of violence. My primary hypothesis is that men who measure as more `masculine' will be more accepting of violence. My secondary hypothesis is that situational contexts are also important for the acceptance of violence. These hypotheses are examined using the Conformity to Masculine Norms Inventory and randomized factorial vignettes. Results indicate that those who more strongly conform to masculine norms are more likely to be accepting of the violence represented in these vignettes.

This research is on the challenges that the state parties faced in including the crime of aggression under the international affairsfuture challenges that might arise in prosecuting the crime of aggression. The crime of aggression, formerly known as crimes against peace, is the use of unlawful force by a state against another state. Its prohibition started before World War One but successful prosecutions for this crime took place after World War Two when Nazi and Japanese leaders were prosecuted by the Allied Powers. The research will analyse some important international criminal law principles that will affect the laws prohibiting aggression since it is an international crime that has to be bound by principles already adopted and received by the international community. The biggest obstacle that the state parties had to overcome was an accepted definition of the crime for purposes of the Rome Statute. A definition was adopted in 2010 at the Kampala Review Conference but at least 30 states parties need to ratify these adoptions that will be reviewed again in 2017. The ICC will only have jurisdiction over this crime if enough ratifications are obtained from the state parties. Other challenges include: personal jurisdiction (who the ICC may prosecute for this crime); the leadership nature of this crime; the exclusion of non-state actors from the definition of this crime; immunity of state leaders that will further complicate their prosecution if responsible for committing aggression; the inclusion of humanitarian intervention as aggression; and the application of the principle of complementarity with regard to the crime of aggression. States, particularly the United States of America, have objected to the inclusion of this crime in the Rome Statute for fear that its nationals (military and political leaders) will be held criminally liable for making political decisions to use military force against another state. Current international affairs will be used to demonstrate why this crime has been difficult to prosecute compared to the other international crimes. After raising the challenges that the ICC might face I am going to offer possible solutions and recommendations that the ICC should first implement to be able to have more successful prosecutions of the crime of aggression. / Dissertation (LLM)--University of Pretoria, 2012. / Centre for Human Rights / unrestricted

The primary objective of the current study involved examining the influence of callous-unemotional (CU) traits on the aggressive behavior and criminal offending of female juveniles committed to a secure juvenile justice facility. A history of physical abuse was examined as a potential moderator of these relationships. The deviant behaviors of peers were examined with respect to the outcomes for the entire sample. A total of 63 female youth incarcerated at a Midwestern state correctional facility participated. Overall levels of callous-unemotional traits were not related to involvement in delinquent activities. However, specific aspects of CU traits were related to engagement in certain types of criminal behavior. Peer delinquency was related to self-reported engagement in criminal activities generally, as well as offenses against persons specifically. CU traits demonstrated significant relationships with measures of aggression, but no significant differences were found with respect to the relationship of CU traits with different types of aggression. Having a history of physical abuse was unrelated to levels of aggression and involvement in delinquency. These findings have implications for prevention and intervention programs in correctional settings and the community. However, potential problems with data collection and measurement of key variables are discussed. Additional research needs to be conducted to determine the mechanisms of the relationships found in this study.

Pain is a sensory experience associated with physical discomfort that is influenced by cognition and emotion and has been linked to an increased risk for aggression. The purpose of the current study was to examine the association between pain and aggression under controlled laboratory conditions using both experimental and non-experimental approaches. The aims of the study were two-fold. First, to manipulate perceived pain tolerance via faux feedback and then observe whether aggression differs as a function of this pain perception manipulation using a laboratory analogue of aggression. Second, to examine whether self-ratings of pain sensitivity and behavioral measures of pain are associated with self-reported or behavioral assessment of aggression. Eighty-three men and women were randomly assigned to one of three conditions: A high pain tolerance feedback group, a low pain tolerance feedback group, and a no pain tolerance feedback (control) group. Participants completed self-report ratings of pain and aggression, including the Life History of Aggression: Aggression subscale, the Buss Perry Aggression Questionnaire: Physical Aggression subscale, and the Pain Sensitivity Questionnaire. Participants then completed an algometer pressure pain task and immediately received high or low pain tolerance feedback (or no feedback) before engaging in an electric shock pain tolerance procedure and subsequently participating in a laboratory task of aggression against an increasingly provocative fictitious "opponent" during a competitive reaction-time task (i.e., the Taylor Aggression Paradigm; TAP). Aggression was operationalized both as the average shock and the number of "extreme" shocks administered to the opponent. The latter were ostensibly twice the opponent's pain threshold. Results indicated that, contrary to the main prediction, individuals who received high pain tolerance feedback tended to select lower mean shocks as provocation increased. Pain sensitivity was also positively related to TAP aggression. These results are consistent with the literature suggesting that low perceived pain tolerance is associated with aggression. However, pressure pain tolerance was positively associated with self-reported aggression, suggesting that the association between pain and aggression is complex, may involve multiple pathways, and is dependent on the method used to assess pain and aggression.

Research on revenge often treats vengeful acts as singular one-way experiences, an approach which fails to account for the social nature and functions of revenge. This dissertation aims to integrate emotional punishment reactions into dynamic revenge sequences to investigate the affective and cognitive consequences of revenge within a social interaction. Exacting revenge can evoke intense affective consequences, from feelings of guilt to the genuine enjoyment of the suffering of others. In Chapter 2, affective responses towards suffering opponents and the regulation of aggression based on the appraisal of distinct suffering indicators were investigated. Results indicate that the observation of opponent pain evokes positive affect (measured via facial muscle contractions during the observation), which is followed by a downregulation of subsequent punishment. Both, positive affective reactions and the downregulation of punishment, were only observed following pain and not sadness expressions. Empathic distress, indexed by negative affective reactions, was only present following the observation of pain in non-provoking opponents. Showcasing the modulation of empathy related processes due to provocation and competition. In Chapter 3, a significant escalation of punishment, when being confronted with Schadenfreude, was observed. Results are interpreted as supporting the assumption that opponent monitoring processes inform subsequent action selection. The observation of opponent smiles led to imitation behavior (facial mimicry), which was partially attenuated due to previous provocation. The different functions of smile mimicry in the context of the aggressive competitive setting are discussed as containing simulation aspects (to aid in opponent understanding) and as a potential mirroring of dominance gestures, to avoid submission. In an additional series of studies, which are presented in Chapter 4, changes in memory of opponent faces following vengeful encounters were measured. Based on provocation, and punishment outcomes (pain & anger), face memory was distorted, resulting in more positive representations of opponents that expressed pain. These results are discussed as evidence of the impact of outcome appraisals in the formation of opponent representations and are theorized to aid empathy avoidance in future interactions. The comparison of desired and observed opponent states, is theorized to result in appraisals of the punishment outcomes, which evoke affective states, inform the action selection of subsequent punishments, and are integrated into the representation of the opponent in memory. Overall, the results indicate that suffering cues that are congruent with the chosen punishment action are appraised as positive, evoking an increase in positive affect. The emergence of positive affect during the observation of successful aggressive actions supports recent theories about the chronification of aggressive behavior based on reinforcement learning. To allow positive affect to emerge, affective empathic responses, such as distress, are theorized to be suppressed to facilitate the goal attainment process. The suffering of the opponent constitutes the proximate goal during revenge taking, which highlights the importance of a theoretical differentiation of proximate and ultimate goals in revenge to allow for a deeper understanding of the underlying motives of complex revenge behavior. / Die bisherige Forschung zu den Mechanismen von Racheverhalten behandelt die Ausübung von Rache häufig als eine singuläre und unilaterale Erfahrung. Diese Herangehensweise berücksichtigt den sozialen Kontext und die Funktion von Rache nur unzureichend. Die vorliegende Dissertation zielt darauf ab, mittels empirischer Befunde emotionale Reaktionen in dynamische Rachesequenzen zu integrieren. Die Ausübung von Rache kann intensive affektive Zustände wie Schuldgefühle bis hin zu dem Empfinden von Freude über das Leid Anderer (Schadenfreude) auslösen. In Kapitel 2 werden Ergebnisse geschildert, welche die unterschiedlichen affektiven Reaktionen des Aggressors in Abhängigkeit zu Indikatoren des Leides des Gegners untersuchen. Im Rahmen der durchgeführten Studien wurde eine positive Reaktion (gemessen anhand von fazialen Muskelaktivierungen) während der Beobachtung von Schmerzausdrücken des Gegners beobachtet. Die positive affektive Reaktion geht mit einer Reduktion der darauffolgenden Strafe einher. Sowohl der positive Affekt als auch die Reduktion von Strafe wurden nur in Folge von Schmerzindikatoren und nicht nach Ausdrücken von Trauer beobachtet. Empathischer Stress nach ausgeführten Rachehandlungen, indiziert durch negative affektive Reaktionen, wurde nur gezeigt, nachdem nicht-provokative Gegner Schmerzreaktionen zeigten. Dies zeigt die Modulation von empathischen Prozessen in Abhängigkeit von Provokation und Konkurrenz. Kapitel 3 beschreibt die signifikante Eskalation von aggressiven Interaktionen durch eine Konfrontation mit Schadenfreude des Gegners während der Bestrafung. Dies lässt darauf schließen, dass die Beobachtung des Gegnerzustandes während der gesamten Interaktion die Wahl von Handlungen beeinflusst. Die Beobachtung des Lächelns beim Gegenüber führt zu Nachahmungsverhalten (faziale Mimikry), welches durch vorherige Provokation graduell abgeschwächt wird. Die verschiedenen Funktionen der Mimikry des Lächelns im Kontext einer aggressiv kompetitiven Situation enthalten Elemente von Simulation, zum besseren Verständnis der Gegnerreaktion, und dienen dazu als potenzielle Reaktion auf Dominanzverhalten Submission zu vermeiden. In einer weiteren Experimentalreihe, beschrieben in Kapitel 4, wird die Integration von erlebter Provokation und daraus resultierenden empfundenen Ärger in die Erinnerung an den Gegner demonstriert. Ergebnisse dieser Studienreine legen nahe, dass die Repräsentation des Gesichtes des Gegners in der Erinnerung basierend auf vorheriger Provokation und distinkten emotionalen gegnerischen Reaktionen auf Strafe (Schmerz & Ärger) systematisch variiert. Gegner, welche Schmerzreaktionen zeigten, wurden mit positiveren Gesichtskonfigurationen repräsentiert, im Gegensatz zu Gegnern, welche Ärger zeigten. Diese Ergebnisse werden als Belege für den Einfluss von Ergebnisbewertungen auf die Formation von Gegnerrepräsentationen und ihren potenziellen Nutzen für die Vermeidung von Empathie in zukünftigen Auseinandersetzungen diskutiert. Aus dem Abgleich zwischen dem gewünschten und beobachteten gegnerischen Reaktionen resultiert eine Bewertung des Erfolgs der Strafe. Dieser Bewertungsvorgang kann positive Affekte auslösen, die als Information in die Wahl der nächsten Handlung einfließen und die Repräsentation des Gegners in der Erinnerung verändern. Die Ergebnisse der hier dargestellten Studien deuten darauf hin, dass Signale des Leidens, die unmittelbar kongruent zu den zuvor gewählten Strafhandlungen sind, als positiv bewertet werden und somit zu einem unmittelbar erlebten positiven Affekt führen. Das Vorhandensein von positivem Affekt während der Beobachtung des leidenden Gegners nach erfolgreicher Bestrafung stimmt mit neueren Forschungsansätzen überein, die Verstärkungslernen als zentralen Prozess bei der Chronifizierung von aggressivem Verhalten postulieren. Das Auftreten von positivem Affekt wird durch die Herabsetzung von affektiv empathischen Prozessen gegenüber dem Gegner ermöglicht. Die Unterdrückung von affektiver Empathie erleichtert hierbei den Prozess der Zielerreichung. Das Leid des Gegners wird als proximales Ziel der Rachehandlung diskutiert. Eine Unterscheidung zwischen proximalen und distalen Zielen bei der Ausübung von Rache ermöglicht ein tieferes Verständnis für die zugrundeliegende Motive komplexen Racheverhaltens.

Love and romantic relationships have the capacity to influence one's welfare in the most profound ways. Intimate partner psychological aggression (IPPA), defined as verbal and nonverbal behaviours that aim to belittle, coerce, isolate, or control (Baldry, 2003; Shorey et al., 2012), is the most prevalent form of partner aggression (Center for Disease Control and Prevention, 2019), and can have significant negative outcomes on its victims. The detrimental outcomes of IPPA warrant additional research on factors that may be associated with its sustained prevalence in men and women. While various studies have revealed that justifying a harmful behaviour can maintain and, in some cases, aggravate the behaviour (e.g., Martens & Kosloff, 2012; Mulder & van Dijk, 2020), few have explored its associations to IPPA. This doctoral dissertation focuses on IPPA and how it is justified. Specifically, the two complementary studies investigated how justifications for using IPPA relate to other features of psychological functioning (e.g., adult romantic attachment, relationship satisfaction, anger management, psychopathy, childhood trauma, drug and alcohol use) to better understand the IPPA phenomenon. The present dissertation is in article format and contains four sections: a general introduction, two articles, and a general discussion. The general introduction presents the topic of the dissertation, defines the primary constructs, states the problem statement, provides a robust theoretical basis, and specifies its main objectives. The two articles contain the following sections: introduction, objectives and hypotheses, method, analyses, results and discussion. Both articles are presented according to the format requested by their respective peer-reviewed journal. Lastly, the general discussion summarizes the findings of both articles, presents their implications and outlines limitations and future directions for prospective studies. All study materials (i.e., ethics approval notice, consent form, self-report measures) are included as appendices. The first study explored the association between how individuals justify their use of IPPA and their adult romantic attachment (i.e., defined through levels of attachment anxiety and attachment avoidance) in Canadian community couples experiencing bi-directional aggression. The sample consisted of 162 adult participants (81 mixed-sex couples). The data were analyzed using structural equation modelling (i.e., actor-partner interdependence model) to test the study's hypotheses, as it is one of few statistical models to account for variances between and within partners. Path analysis based on the APIM model revealed statistically meaningful associations between attachment anxiety and all types of justifications, as well as no statistically significant associations between attachment avoidance and the justifications. In addition, a small but significant association was found between men's attachment avoidance and women's use of external justifications for their use of IPPA. The results are discussed using the theoretical lenses of attachment theory and cognitive dissonance, and highlight the significance of justifications in adults with higher levels of attachment anxiety. The second study investigated a new typology of men's use of IPPA. A sample of 456 men seeking therapeutic services for their couple relationship problems was recruited to complete a battery of questionnaires. Latent profile analyses revealed a final five-profile solution model. The five profiles were then compared on a series of IPPA-related variables to offer more descriptive information on each profile. Overall, the results emphasize the importance of inquiring about the justifications accompanying men's use of IPPA to support the conceptualization and orient treatment for this population. Taken together, these independent studies provide a complementary overview of the associations between justification for IPPA use and other features of psychological functioning. While the first study focuses on the associations between justifications and romantic attachment, the second uses justifications as an indicator variable to classify participants and then compares the profiles on a multitude of variables, including adult romantic attachment. Moreover, the studies' complementary analytical and methodological approaches offer results that, combined, refer to men and women, individuals and couples, and investigates justification across a community and a middle-ground sample (i.e., sharing characteristics of both a community and a clinical sample). Moreover, the combination of the studies’ variable-centered analyses (i.e., study 1; focus the analysis on the relationship among variables) and person-centered analyses (i.e., study 2; focus the analysis on the classification of individuals) reflects an important strength of this dissertation. The results highlight the importance of considering the justifications for using IPPA and stress its relevance with other dimensions of psychological functioning. The results contribute to the literature and overall understanding justifications for intimate partner aggression and add support to some of the theories that inform conceptualizations and treatment of individuals who are dealing with IPPA.

Participants (N = 73) in the present research were assigned to play a violent videogame (Super Smash Brothers) with either a supportive or an ambivalent friend. Orthogonal to this manipulation, participants were assigned to play the game either competitively or cooperatively. Subsequent aggression toward their friend was assessed by measuring participants' competitive or cooperative behavior in a Prisoner's Dilemma game. Results revealed no differences in aggression as a function of friendship type or game strategy, although means were in predicted directions. The influence of context on exposure to violent media is discussed, as are issues of power and sample type as possible reasons for the nonsignificant findings.

This 2 x 3 factorial study focuses on roles of different rejection types (instigating force) and lack of self-regulation (weak inhibiting force) on the commission of obsessive relational intrusion (ORI). Rejection was manipulated through vignettes depicting no rejection or one of two types of romantic rejection: an explicit rejection (rejection that makes an internal attribution to the rejected as cause of relationship ending) or a passive rejection that “lets the pursuer down easy” (external attributions for relationship demise). Self-regulation was manipulated through a thought suppression exercise (2 conditions: free writing/no suppression vs. restricted writing/thought suppression). After scenario and writing exercise, participants (N = 221) rated their likelihood of thinking or engaging in ORI. A main effect of rejection and an interaction between rejection and self-regulation were observed. Participants explicitly rejected reported higher scores for aggressive acts compared to participants passively rejected. The difference was exacerbated with depleted self-regulation.
