Investigating sexual harassment in online video games: How personality and context factors are related to toxic sexual behaviors against fellow players

Online video games are social spaces for players from around the world. They use this space to form communities, relationships, and identities. However, gaming communities are not always welcoming, and some are even perceived as being “toxic.” A prevalent issue is online sexual harassment, which is keeping many women from participating in the gaming community. Research on the factors contributing to the problem is limited, though. The present study replicates and expands previous research, using a sample of 856 online gamers. The study supports earlier findings that found hostile sexism and social dominance orientation as predictors of sexual harassment perpetration in online video games. In addition, we expanded the previous research with additional predictors: machiavellianism, psychopathy, and gamer identification predicted higher sexual harassment perpetration. Our results have implications for the gaming community's role in curtailing sexual harassment and making itself a more inclusive community.     

Attack priming and satiation in female golden hamsters: Tests of some alternatives to the aggression arousal interpretation

“Priming” a female hamster by allowing it a single attack on an intruder placed into its home cage transiently decreases the latency and increases the probability of attack on a second trial. Although we have previously argued that this priming effect reflects an increase in aggressive arousal, an alternative interpretation is that the fear elicited by placing a foreign object into the subject's home cage is reduced when it happens again on the second trial. Another interpretation is that priming is an effect of intruder novelty, i.e., the subject perceives a difference between the first and second intruders which causes it to attack the second more quickly. Experiment 1 compared the standard two trial paradigm with different intruders to trials in which (1) the first intruder was withdrawn and used again in the second trial, and (2) the intruder remained in the cage following the first attack. All intruders were pretreated with the analgesic-sedative methotrimeprazine to reduce the variability of their behavior. Neither hypothesis tested in Experiment 1 was supported, strengthening the interpretation of attack priming as a manipulation that affects primarily internal motivational mechanisms specific to aggression. Allowing a hamster to carry out a protracted series of attacks produces a “satiation” effect that is the reverse of priming, i.e., the latency of a subsequent attack is increased and its probability reduced. It is possible that the attack satiation observed in our earlier studies was not the result of processes internal to the subject, but could have been due to habituation to a particular intruder or to certain stimuli emitted by it during the protracted interaction. In Experiment 2 subjects were given three sessions of 10 successive trials using either 1 intruder presented repeatedly, 2 intruders presented alternately, or 10 different intruders presented once each. No difference among conditions was found in this study either suggesting that subject's aggressive behavior is insensitive to whatever changes may occur in intruders' behavior or other stimulus characteristics when they have been treated with methotrimeprazine. The lack of differences among test conditions in both experiments is most likely due to the efficacy of the drug in “standardizing” intruder behavior. Experiment 2 also revealed an interesting difference in two measures of attack latency. The time elapsing between intruder presentation and attack, i.e., the standard measure of latency, decreased from the first to the fourth trail; it then increased steadily over the remaining trials. The cumulative time that the subject remained in contact with the intruder prior to attack, a measure more indicative of attention to the intruder, dropped to an asymptotic value by the second trial. This difference suggests that the satiation effect may be accounted for by subjects' increasing avoidance of the intruders over trails, perhaps as a way of regualting their level of aggressive arousal.     

Role of serotonin in human aggressive behaviour

This study aimed to evaluate a peripheral serotonergic marker, ³H-imipramine (³H-IMI) binding to platelet membranes, in a group of severely aggressive subjects (A), institutionalized since childhood for mental retardation, as compared with suicide attempters (S) and healthy controls (H). The maximum binding capacity of ³H-IMI to platelet membranes was statistically lower in (A) and (S) than in (H). In addition, a statistically significant difference was observed between the Bmax values of aggressive subjects and those of suicide attempters. No changes in the dissociation constant (Kd) of IMI binding were observed. These data provide further supporting evidence for the hypothesis of an abnormality of the 5HT system in aggressive behaviour and suggest that such an abnormality, as reflected by platelet markers, is more severe in suicide attempters. © 1993 Wiley-Liss, Inc.     

Influence of contextual information on observers' perceptions of actors' intentions to harm others

Previous examinations of perceptions of aggressive behaviors have used static stimulus presentations (e.g., photographs or slides). This investigation examined the impact of varying amounts of geographical and temporal contextual information on observers' perceptions of actors' intentions to physically and psychologically (intimidate) harm others. Participants (51 elite ice hockey players) were randomly assigned to view one of three video-taped presentations showing eight ice hockey behaviors in either a) a dynamic mode with contextual information, b) a dynamic mode with no context, or c) a static, “freeze-frame” mode. MANOVA results showed that non-aggressive stimuli were perceived as less aggressive, and aggressive stimuli were perceived as more aggressive in dynamic presentations with context than in static presentations. Based on these findings, it is suggested that future research focussing on perceptions of aggressive behavior utilize a dynamic stimulus presentation containing context material. © 1996 Wiley-Liss, Inc.     

Aggressive behaviour in free-ranging guanacos and vicuñas in Argentina

The aggressive behaviour of free-ranging guanacos and vicuñas, living in sympatry in Catamarca Andes, Argentina, was analysed in relation to their social organisations. These organisations include territorial family units, solo males (territorial or not), and bachelor groups. In both guanacos and vicuñas, family groups tended to have higher rates of agonistic interactions than bachelors and to be frequently involved in aggressive encounters, whereas bachelor groups showed the opposite tendencies. Encounters between family groups and solo males were more frequent than expected. Bachelors acted almost exclusively as recipients of aggressive interactions, whereas solitary and family males frequently initiated encounters. Family groups adopted different behaviours towards bachelors in the two camelids. In guanacos, the latter were simply ignored, whereas in vicuñas (where they tend to compete for food with families) bachelors were consistently attacked by families. The behaviour of solitary males showed the main difference between the two species. Guanaco solo males had a much more aggressive attitude than vicuña counterparts. Their proportion in guanaco population was also unexpectedly high. These results suggest that, in the less rigid organisation of guanaco society, the behaviour of solitary males is adopted by a number of adult males in an attempt to breed. © 1996 Wiley-Liss, Inc.     

Maternal territoriality as an offspring defense strategy in red swamp crayfish (Procambarus clarkii,Girard)

The offspring‐defense hypothesis of maternal territoriality in solitary and semisocial mammals [Wolff JO and Peterson JA. 1998. Ethol Ecol Evol 10:227–239] was evaluated in another taxon using maternal and nonmaternal female red swamp crayfish (Procambarus clarkii), a freshwater decapod crustacean that shows pronounced shelter‐related maternal aggression. The maternal females were of three different categories: (1) ovigerous, (2) carrying primarily stage 1 offspring, or (3) tending offspring that were primarily stage 2. Each female was in residence in an individual aquarium containing only a gravel substrate for 24 hr prior to serial intrusions by male conspecifics. Virtually all of the residents, maternal and nonmaternal, excavated a depression (shelter) in the substrate prior to the first intrusion. The results showed that residents in each of the maternal categories won a significantly higher proportion of their encounters than did the nonmaternal residents, which showed only negligible defense and lost every encounter. However, there were no significant differences in encounter outcomes between the maternal resident categories. There was clear defense of the shelter by maternal females, with virtually all fighting being in or around it, thus demonstrating stable, heightened territorial defense throughout these maternal phases of reproduction. This support of the offspring‐defense hypothesis of maternal territoriality is the first such evidence for a freshwater crustacean and is very similar to that recently reported in a related marine decapod, the American lobster (H. americanus).

Schooling Bodies Through Physical Education: Insights from Social Epistemology and Curriculum History

Using mainly historical material fromAustralia, the paper seeks to understand earlyforms of school physical training, sport andmedical inspection as specialised means ofschooling bodies. The study adopts a socialepistemological perspective in seeking tounderstand the meaning-in-use of notions suchas physical training. It explores the socialconsequences of the practices carried out inthe name of physical training, particularly inrelation to shifts in the social regulation ofbodies over time from a mass, externalised, andcentralised form to a relatively moreindividualised, internalised and diffuse form.This focus on the body is of key importance fora social epistemological study of physicaleducation because it forces us to look closelyat the practices constituting physicaleducation.     

Computer-assisted observer training

Computerized interactive videotapes were used to train college students to use a 10-second partial-interval observational recording system. Students viewed videotapes and scored response occurrences on a computer keyboard. Incorrect scoring resulted in immediate computerized feedback and rescoring.     

THE USE OF PEER MONITORS TO REDUCE NEGATIVE INTERACTION DURING RECESS

The negative interactions of a mildly retarded child, Dennis, were reduced in three daily recess periods, withthe use of a point system. Adult monitors initiatedthe intervention inthe morning recess; reductions achieved during adult monitoring were maintained in that recess during two subsequent conditions: peer monitoring and self-monitoring. Dennis' negative interactions were reduced next inthe afternoon recess by peer monitors. Again, reductions were maintained during a subsequent self-monitoring condition. Finally, duringthe noon recess, Dennis was trained to serve as a peer monitor for Ed, a moderately retarded classmate. Dennis' rate of negative interactions quickly decreased following his appointment as a peer monitor. The results show that a point system, originally designed for adult monitoring, can be adapted without loss of program effectiveness for peer monitoring or self-monitoring. The results also suggest that classmates who serve as peer monitors may benefit significantly from their role. The conditions under which these therapeutic effects occur andthe role that treatment order effects may play in this process require further investigation.
