Neuromodulation can reduce aggressive behavior elicited by violent video games

Research has shown that exposure to violent media increases aggression. However, the neural underpinnings of violent-media-related aggression are poorly understood. Additionally, few experiments have tested hypotheses concerning how to reduce violent-media-related aggression. In this experiment, we focused on a brain area involved in the regulation of aggressive impulses—the right ventrolateral prefrontal cortex (rVLPFC). We tested the hypothesis that brain polarization through anodal transcranial direct current stimulation (tDCS) over rVLPFC reduces aggression related to violent video games. Participants (N = 79) were randomly assigned to play a violent or a nonviolent video game while receiving anodal or sham stimulation. Afterward, participants aggressed against an ostensible partner using the Taylor aggression paradigm (Taylor Journal of Personality, 35, 297–310, 1967), which measures both unprovoked and provoked aggression. Among those who received sham stimulation, unprovoked aggression was significantly higher for violent-game players than for nonviolent-game players. Among those who received anodal stimulation, unprovoked aggression did not differ for violent- and nonviolent-game players. Thus, anodal stimulation reduced unprovoked aggression in violent-game players. No significant effects were found for provoked aggression, suggesting tit-for-tat responding. This experiment sheds light on one possible neural underpinning of violent-media-related aggression—the rVLPFC, a brain area involved in regulating negative feelings and aggressive impulses.     

Eye tracking reveals the cost of switching between self and other perspectives in a visual perspective-taking task

Previous studies have shown that while people can rapidly and accurately compute their own and other people’s visual perspectives, they experience difficulty ignoring the irrelevant perspective when the two perspectives differ. We used the “avatar” perspective-taking task to examine the mechanisms that underlie these egocentric (i.e., interference from their own perspective) and altercentric (i.e., interference from the other person’s perspective) tendencies. Participants were eye-tracked as they verified the number of discs in a visual scene according to either their own or an on-screen avatar’s perspective. Crucially in some trials the two perspectives were inconsistent (i.e., each saw a different number of discs), while in others they were consistent. To examine the effect of perspective switching, performance was compared for trials that were preceded with the same versus a different perspective cue. We found that altercentric interference can be reduced or eliminated when participants stick with their own perspective across consecutive trials. Our eye-tracking analyses revealed distinct fixation patterns for self and other perspective taking, suggesting that consistency effects in this paradigm are driven by implicit mentalizing of what others can see, and not automatic directional cues from the avatar.     

The pleasure is momentary…the expense damnable?: The influence of pornography on rape and sexual assault

The effects of pornography, whether violent or non-violent, on sexual aggression have been debated for decades. The current review examines evidence about the influence of pornography on sexual aggression in correlational and experimental studies and in real world violent crime data. Evidence for a causal relationship between exposure to pornography and sexual aggression is slim and may, at certain times, have been exaggerated by politicians, pressure groups and some social scientists. Some of the debate has focused on violent pornography, but evidence of any negative effects is inconsistent, and violent pornography is comparatively rare in the real world. Victimization rates for rape in the United States demonstrate an inverse relationship between pornography consumption and rape rates. Data from other nations have suggested similar relationships. Although these data cannot be used to determine that pornography has a cathartic effect on rape behavior, combined with the weak evidence in support of negative causal hypotheses from the scientific literature, it is concluded that it is time to discard the hypothesis that pornography contributes to increased sexual assault behavior.     

Super-recognizers: People with extraordinary face recognition ability

We tested 4 people who claimed to have significantly better than ordinary face recognition ability. Exceptional ability was confirmed in each case. On two very different tests of face recognition, all 4 experimental subjects performed beyond the range of control subject performance. They also scored significantly better than average on a perceptual discrimination test with faces. This effect was larger with upright than with inverted faces, and the 4 subjects showed a larger “inversion effect” than did control subjects, who in turn showed a larger inversion effect than did developmental prosopagnosics. This result indicates an association between face recognition ability and the magnitude of the inversion effect. Overall, these “super-recognizers” are about as good at face recognition and perception as developmental prosopagnosics are bad. Our findings demonstrate the existence of people with exceptionally good face recognition ability and show that the range of face recognition and face perception ability is wider than has been previously acknowledged.     

Gut Reactions: Moral Conviction, Religiosity, and Trust in Authority

ABSTRACT— Theory and research point to different ways moral conviction and religiosity connect to trust in political authorities to decide controversial issues of the day. Specifically, we predicted that stronger moral convictions would be associated with greater distrust in authorities such as the U.S. Supreme Court making the "right" decisions regarding controversial issues. Conversely, we predicted that stronger religiosity would be associated with greater trust in authorities. We tested these hypotheses using a survey of a nationally representative sample of Americans (N = 727) that assessed the degree to which people trusted the U.S. Supreme Court to rule on the legal status of physician-assisted suicide. Results indicated that greater religiosity was associated with greater trust in the U.S. Supreme Court to decide this issue, and that stronger moral convictions about physician-assisted suicide were associated with greater distrust in the U.S. Supreme Court to decide this issue. Also, the processes underlying religious trust and distrust based on moral convictions were more quick and visceral than slow and carefully considered.     

Seeing My World in a Million Little Pieces: Narcissism, Self-Construal, and Cognitive–Perceptual Style

ABSTRACT In 4 studies we examine the association between narcissism, self-construal, and cognitive–perceptual style, hypothesizing that high self-focus in combination with low other-focus (i.e., social atomization) is related to an analytic cognitive–perceptual style. Participants completed the Narcissistic Personality Inventory, the Self-Construal Scale, and measures of cognitive–perceptual style such as the Analysis-Holism Scale, the Embedded Figures Test, a visual illusion test, and a measure of the representativeness heuristic. We found evidence for a decontextualized cognitive–perceptual style in socially atomized participants, which included those high in narcissism and also those who had a combination of high independent and low interdependent self-construal. A meta-analytic integration of our findings found that narcissism was positively related to independent and negatively related to interdependent self-construal, and mediation analyses found some evidence that the relationship between self-construal and cognitive–perceptual style is partially mediated by narcissism.     

What if the elephant speaks? Kant's Critique of Judgment and an Übergang problem in John Hick's philosophy of religious pluralism

In the Critique of Judgment, Kantattempts to unravel the problem of Übergang that threatens his CopernicanRevolution. Having opened up a ``chasm' betweensensible and supersensible, betweenepistemological and ontological, Kant facesboth the specter of empirical chaos in whichthe noumenal refuses to conform to theunderstanding's attempts to legislate over themanifold of intuition, and the problem offinding a place for freedom to have effectswithin the seamless phenomenal realm ofefficient causality. Central to Kant's attemptto overcome these problems is his notion of theheautonomy of reflective judging, in whichjudgment subjectively legislates its ownactivity. The net effect of this strategy isto preserve the integrity of the architectonicby permitting judgment use of ontologicalprinciples in regulating its own activity, butalways placing these ontological principlesunder an epistemological ``as if' that cannot becarried over into the noumenal realm (e.g.,judgment can subjectively operate under theprinciple that the world appears ``as if' it haspurpose, but this cannot be thought to apply tothe noumenal). Kant shields his architectonicby allowing it to encounter onlyepistemologically neutered noumena. This paperargues that Hick faces an analogousÜbergang problem, explores his``heautonomous' attempt to blunt the problem,and concludes that the attempt fails, leavingHick with an unresolved problem of``onto-ethical discontinuity.'     

Why Are Women Paid Less than Men, but Given Higher Raises?

We replicated and extended a largely ignored pattern of findings in the literature, namely, that women receive lower base pay but higher pay increases than men within the same organization. Despite the fact that we were able to explain about 95% of the variance in base pay, gender differences remained. We found that unequal starting pay was a significant factor in subsequent base pay. In addition, we compared two explanations for the finding that women receive higher pay raises than men. The results suggested that structural features of the pay increase system, rather than the reduction of stereotypes, seemed to account for women receiving higher pay increases.     

Correlation of Self-Perception and Image of Christ Using the Five-Factor Model of Personality

In this study, the relationship between one’s self-perception of personality and his or her image of Jesus Christ was studied within a sample of 153 undergraduate students, of whom 130 were Christian and 23 were non-Christian; 23 Protestant pastors; and 55 Protestant laypersons. Using two forms of the NEO Personality Inventory (Self and Observer), ratings of the Big Five personality factors were obtained for both self and Jesus Christ. Results indicated significant positive correlations between ratings of self and Christ in each of the subgroups of Christian individuals. No correlations were found between ratings of self and Christ for the non-Christians. A repeated-measures ANOVA revealed significant differing correlations between groups. Christian persons may project perceptions onto Christ or attempt to mold themselves in a way more consistent with their own images of Christ. Further implications of the results as well as direction of the relationship between self-perception and image of Christ are discussed.
