Aggression-consistent, -inconsistent,and -irrelevant priming effects on selective exposure to media violence

Priming with aggressive concepts increases males' attraction to media violence. It was hypothesized that priming with schema-irrelevant concepts would decrease interest relative to the effects of schema-relevant concepts, whether or not the schema-relevant concepts were also schema-consistent. Thirty male undergraduates used lists including aggressive (schema-consistent and schema-relevant), positive or prosocial (schema-inconsistent yet relevant), or entirely neutral (schema-irrelevant) words to write short stories (priming task), then received an opportunity to select videotaped film clips for viewing. Subjects primed by aggressive word lists included more aggression, anger, fear, and violence in their stories than did those in the aggression-inconsistent and aggression-irrelevant conditions, whereas aggression-inconsistent priming yielded more fun, helping, and joy than did other conditions. Aggressively primed subjects expressed more interest in films containing violence and hostility than did neutrally primed subjects, whereas aggression-inconsistent priming did not differ significantly from either aggressive (schema-consistent) or neutral (schema-irrelevant) priming. Findings indicate that the aggressive priming activates aggressive concepts that make violence and hostility more salient to individuals. Because male undergraduates typically express interest in violence, enhanced salience leads to increased interest. © 1992 Wiley-Liss, Inc.

Intersexual aggression and male sexual activity in captive rhesus macaques

Rape has been posited to be an outgrowth of male reproductive strategies. Forced copulations may have evolved as a consequence of the low parental investment made by males in producing and raising offspring. We designed a laboratory experiment which paired rhesus macaque males with females in order to assess the influence of intersexual aggression on male sexual activity. Younger and older adult males had comparable levels of sexual behavior, but younger males were more aggressive towards females than were older males. In addition, females threatened younger males more than older males. Male attacks on females did not result in sexual intercourse. On the contrary, a negative correlation existed between male aggression towards females and male success at achieving intromissions. Female aggression towards males appeared to be an effective tactic which reduced the chances of sexual intercourse. We conclude that intersexual aggression acts either as a mechanism of dominance assertion or as a means to increase spatial distance between individuals. These data do not support the idea that rape in humans has an evolutionary foundation derived from male reproductive strategies.     

Predatory aggression in the mink (Mustela vison): Roles of serotonin and food satiation

5-Hydroxytrypotophan at a dose of 50 mg/kg intraperitoneally (i.p.) sharply increased neural serotonin (5-HT) levels in mink and considerably inhibited that animal's predatory attack on rats. Intraperitoneal injection of 5-HT (10 and 20 mg/kg) did not influence such rat-killing. Neural levels of 5-HT or 5-hydroxyindoleacetic acid (5-HIAA) and subsequent aggression by the predator did not change to any great degree after ingestion of a single meal. Abundance of natural mink food for 3 days was associated with an increased level of 5-HIAA in the lateral hypothalamus and the amygdala as well as with an increased latency to attack and to kill rats. 5-HT seems to represent an endogenous factor that inhibits predatory attack by the mink; this effect appears to function through increased metabolism of 5-HT in some brain regions, which is evident after abundant intake of tryptophan with the natural diet.     

Robots as Malevolent Moral Agents: Harmful Behavior Results in Dehumanization,Not Anthropomorphism

A robot's decision to harm a person is sometimes considered to be the ultimate proof of it gaining a human-like mind. Here, we contrasted predictions about attribution of mental capacities from moral typecasting theory, with the denial of agency from dehumanization literature. Experiments 1 and 2 investigated mind perception for intentionally and accidentally harmful robotic agents based on text and image vignettes. Experiment 3 disambiguated agent intention (malevolent and benevolent), and additionally varied the type of agent (robotic and human) using short computer-generated animations. Harmful robotic agents were consistently imbued with mental states to a lower degree than benevolent agents, supporting the dehumanization account. Further results revealed that a human moral patient appeared to suffer less when depicted with a robotic agent than with another human. The findings suggest that future robots may become subject to human-like dehumanization mechanisms, which challenges the established beliefs about anthropomorphism in the domain of moral interactions.

Indicators of Affect Dynamics: Structure,Reliability, and Personality Correlates

Researchers are increasingly interested in the affect dynamics of individuals for describing and explaining personality and psychopathology. Recently, the incremental validity of more complex indicators of affect dynamics (IADs; e.g. autoregression) has been called into question (Dejonckheere et al., 2019), with evidence accumulating that these might convey little unique information beyond mean level and general variability of emotions. Our study extends the evidence for the construct validity of IADs by investigating their redundancy and uniqueness, split-half reliability based on indices from odd-numbered and even-numbered days, and association with big five personality traits. We used three diverse samples that assessed daily and momentary emotions, including community participants, individuals with personality pathology, and their significant others (total N = 1192, total number of occasions = 51 278). Mean and variability of affects had high reliability and distinct nomological patterns to big five personality traits. In contrast, more complex IADs exhibited substantial redundancies with mean level and general variability of emotions. When partialing out these redundancies by using residual variables, some of the more complex IADs had acceptable reliability, but only a few of these showed incremental associations with big five personality traits, indicating that IADs have limited validity using the current assessment practices. © 2020 The Authors.

Imagined contact and mental illness stigma in an Asian context: Bolstering the effect and examining the impact of factual information

Imagined contact can be effective at reducing social stigma. However, the effect may depend on the strength of the stigma held. We tested the robustness of imagined contact in an Asian setting where stigmatization of mental illness is stronger than in Western countries. In Experiment 1 (n = 167) with five conditions, only an enhanced version of positive imagined contact was able to decrease stigma towards people with schizophrenia through decreasing intergroup anxiety. Given the potential discrepancy between imaginations and reality about experiences with stigmatized groups, in Experiment 2 (n = 121), we tested the hypothesis that after presenting participants with factual information about a mental illness group, imagined contact might backfire, resulting in more negative perceptions. However, enhanced imagined contact alongside factual message about schizophrenia did not increase stigma. The backfiring hypothesis was therefore not supported. Nevertheless, providing realistic information did negate the positive effects of enhanced imagined contact on stigma reduction. In both experiments, we also showed that intergroup anxiety mediated the effect of enhanced imagined contact on various measures of stigma.
