An aggression machine I. The intensity of aggressive defence aroused by aggressive offence
1973
PitkAnen, L. An aggression machine. I. The intensity of aggressive defence aroused by aggressive offence. Scand. J. Psychol., 1973, 14, 56–64.-Sixty 9-year-old boys were tested with an aggression machine (PAM) designed by the writer. PAM allows the variation of both S (light) and R (pressing a button) intensities. The stimuli and responses were given the designations of offensive and defensive aggression, respectively. The following main hypotheses were supported: (1) The intensity of impulsive aggressive defence to an aggressive offence was adapted to the intensity of attack. (2) The intensity of aggressive defence was determined by the authority of the attacker, the defence being stronges…
Successful intermale aggression and conditioned place preference in mice
1995
A. SALVADOR AND V. M. SIMON. Successful intermale aggression and conditioned place preference in mice. PHYSIOL BEHAV 58(2) 323-328, 1995.--This study assessed the reinforcing properties of successful intermale agonistic encounters between OFI male mice using the conditioned place preference paradigm. A three compartment apparatus was used and the procedure consisted of three phases: preconditioning (3 days), conditioning (8 days) and postconditioning (3 tests). Individually housed male mice were allocated to two groups. The aggression group confronted docile opponents in the preconditioning "less-preferred" compartment and were left alone in the "preferred" one. The control group was left a…
Social experience and pheromonal perception can change male-male interactions in Drosophila melanogaster
2005
0022-0949 (Print) Comparative Study Journal Article Research Support, Non-U.S. Gov't; Social interaction with conspecifics can influence the developing brain and behaviour of the exposed animal. This experience can involve the exchange and retention of visual, chemical, acoustic and tactile signals. When several Drosophila melanogaster male flies are associated with mated females in the presence of food, they show frequent aggressive interactions. To measure the role of social experience on male-male interaction, two tester males - naive or exposed to sibling(s) during a variable period of their adult development - were confronted in the absence of female and food. The two males displayed h…
Raiders from the sky: slavemaker founding queens select for aggressive host colonies.
2012
Reciprocal selection pressures in host–parasite systems drive coevolutionary arms races that lead to advanced adaptations in both opponents. In the interactions between social parasites and their hosts, aggression is one of the major behavioural traits under selection. In a field manipulation, we aimed to disentangle the impact of slavemaking ants and nest density on aggression of Temnothorax longispinosus ants. An early slavemaker mating flight provided us with the unique opportunity to study the influence of host aggression and demography on founding decisions and success. We discovered that parasite queens avoided colony foundation in parasitized areas and were able to capture more broo…
Acceptability of Family Violence: Underlying Ties Between Intimate Partner Violence and Child Abuse
2018
Intimate partner violence (IPV) and child abuse (CA) are two forms of family violence with shared qualities and risk factors, and are forms of violence that tend to overlap. Acceptability of violence in partner relationships is a known risk factor in IPV just as acceptability of parent–child aggression is a risk factor in CA. We hypothesized that these acceptability attitudes may be linked and represent the expression of a general, underlying nonspecific acceptance of violence in close family relationships. The sample involved 164 male IPV offenders participating in a batterer intervention program. Implicit measures, which assess constructs covertly to minimize response distortions, were a…
Interaction of morphine and haloperidol on agonistic and motor behaviors of male mice.
1997
To further clarify the interaction between opioid and dopaminergic systems, the effects of simultaneous administration of morphine hydrochloride (1.25 or 2.5 mg/kg) and haloperidol (0.1 mg/kg) on aggressive behavior of male mice were explored. Isolated male mice (experimental animals) were confronted in a neutral area with anosmic, group-housed consepecifics (standard opponents) 30 min after injection of both compounds, and aggression was evaluated by estimation of times allocated to 11 different behavioral categories. In the first experiment (which functioned as a pilot study), the two doses of morphine were explored. In the second one, incorporating a more complete experimental design, on…
Authoritarianism and the transgenerational transmission of corporal punishment.
2019
Abstract Background Authoritarianism, firstly described by Horkheimer in 1936, is characterized by submission to authorities, aggression against subordinates and conventionalism. Authoritarianism is discussed as major contributor for right-wing attitudes. Horkheimer hypothesized that authoritarianism has its origin in the experience of harsh parenting and exposure to corporal punishment (CP) by authoritarian parents. The other way around, literature points towards an association between conventionalism and support of CP as disciplinary method, suggesting a role of authoritarianism in the vicious cycle of transgenerational transmission of CP. Objective We aimed to assess the association of a…
Blaming the Victim: The Effects of Extraversion and Information Disclosure on Guilt Attributions in Cyberbullying
2013
Cyberbullying victims' success in coping with bullying largely depends on schoolmates and other bystanders' social support. However, factors influencing the degree of social support have as yet not been investigated. In this article, the concept of victim blaming is applied to cyberbullying incidents. It is assumed that a cyberbullying victim receives less social support when the victim's behavior is perceived as very overt. It is further assumed that this effect's underlying process is the partial attribution of responsibility for the incident to the victim and not to the bully. The hypotheses are tested with a 2×2 online experiment. In this experiment, varying online self-presentations of…
One-sided and mutually aggressive couples: Differences in attachment, conflict prevalence, and coping
2015
Contains fulltext : 150212.pdf (Publisher’s version ) (Closed access) This study investigated concurrent links between adolescent romantic couples’ reports of aggression (relational and physical) and relationship functioning (e.g., attachment security, conflict prevalence, coping strategies, jealousy, and affiliative and romantic relationship quality) using a pattern-oriented approach. The sample included 194 romantic partner dyads (Mage = 16.99 years for females and Mage = 18.41 years for males). A hierarchical cluster analysis identified five distinct subgroups of dyads based on male and female reports of relational and physical aggression, ranging from nonaggressive couples (42%), to tho…
An aggression machine. II. Interindividual differences in the aggressive defence responses aroused by varying stimulus conditions.
1973
PitkAnen, L. An aggression machine. II. Interindividual differences in the aggressive defence responses aroused by varying stimulus conditions. Scand. J. Psychol., 1973, 14, 65–74.-The subjects, six aggressive and nonaggressive groups of ten 9-year old boys, selected by rating method, were tested with an “aggression machine” (PAM) constructed by the writer. The varying stimulus conditions included two situations of impulsive aggression and six variations of specified attackers. The results showed that (1) the larger part of the variance of the intensity of aggression in the PAM was accounted for by the situational variations than by interindividual differences in coping with thwarting situa…
