This article explores the notion that scientific research programs and empirical findings are fundamentally devalued when they threaten a perceiver's social identity. Findings from three studies show the following: (1) identification with the group of “gamers” (i.e., people who play video games on a regular basis) influences the extent to which perceivers devalue research suggesting that playing violent video games has negative consequences; (2) this effect is mediated by the feeling that the group of gamers is being stigmatized by such research (Studies 1 and 2) as well as by anger about this research (Study 2); (3) the effect of in‐group identification on negative research evaluations cannot be explained by attitude or behavioral preference inconsistency (Studies 1 and 3); and (4) strongly identified gamers not only devalue a specific scientific study but also generalize their negative evaluations to the entire field of violent video games research (Study 3). The findings suggest that the influence of social identity processes on the evaluation of research is larger than it has previously been recognized. Implications of these findings for science communication are discussed. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

Our study sought to characterize mood disordered suicide ideators and attempters 50 years and older admitted to a psychiatric ward either for a recent suicide attempt or for ongoing suicidal ideation. We enrolled 50 patients with suicide ideation consecutively admitted to an inpatient department and 50 patients admitted for a suicide attempt made in the last 48 hours. Suicide attempters more frequently had low social support and an age of onset of mood disorder of 46 years and older, and less frequently had a history of suicidal behaviors in the family members and pharmacological treatment, despite the fact that the groups did not differ with regard to antidepressants prescribed. The groups were not distinguishable based on several variables assumed to be risk factors for suicide behavior, such as proximal life events and stressors or alcohol use disorders. In both samples, comorbidity with organic diseases, the presence of stressful life events in the past 12 months, and a diagnosis of major depression were frequently reported. In conclusion, the presence of low social support and the absence of a pharmacotherapy may increase suicidal behaviors in patients at risk. 相似文献

Suicide attempters who met criteria for borderline personality disorder (BPD) comorbid with major depressive disorder (MDD) were compared to both suicide attempters suffering from MDD alone and to attempters with comorbid MDD and other personality disorders (PD). Participants were 239 (158 patients with comorbid PD and 81 patients with MDD without comorbidity) inpatients consecutively admitted after a suicide attempt made in the last 24 hours. Suicide attempters with comorbid MDD and BPD had more frequent previous suicide attempts and were more likely to have a history of aggressive behaviors and alcohol and drug use disorders compared with patients suffering from MDD without Axis II comorbidity. 相似文献

Differences between groups in socio‐economic status (SES) are becoming more salient nowadays. In this context, we examined the animalistic and mechanistic dehumanization that both low and high‐SES groups may experience respectively by conducting three studies. In study 1, we manipulated the SES of two fictitious groups (low vs. high‐SES) and measured the humanity ascribed to them. Results showed that the low‐SES group was animalized in comparison with the high‐SES group, which was mechanized. In study 2, we manipulated the humanity of two fictitious groups by describing them as animals or machines and measured the perceived SES of the groups. Participants tended to attribute lower SES to the group described as animals and higher SES to the group described as machines. Finally, in study 3, we used an Implicit Association Test to replicate the results of studies 1 and 2. Taken together, these studies show that low‐SES groups are considered as animal‐like whereas high‐SES groups are seen as robot‐like. We discuss the implications of these findings in relation to the justification of income inequality within our society. 相似文献

Recent scholarship indicates that explicitly listing eligibility requirements on Amazon’s Mechanical Turk can lead to eligibility falsification. Offering a conceptual replication of prior studies, we assessed the prevalence of eligibility falsification and its impact on data integrity. A screener survey collected the summer before the 2016 presidential election assessed political affiliation. Participants were then randomly assigned to be exposed to a second survey link for which they were eligible or ineligible. There was a significant interaction such that the differences between self‐reported Republicans and Democrats on outcome measures (e.g., attitudes toward Hillary Clinton), were smaller among participants that were falsifying eligibility (i.e., imposters) than those that were not (i.e., genuine participants). Moreover, for most outcomes, imposters put forth responses that were significantly different from the responses put forth by those in the political party with which imposters were pretending to be affiliated. Imposters’ responses were also significantly different from participants in the political party with which imposters initially claimed to genuinely belong. For example, those who self‐reported themselves as Democrats on the screener survey but responded to a survey for “only Republicans” (i.e., imposter Republicans), reported more favorable attitudes toward Donald Trump than genuine Democrats, but indicated less favorable attitudes toward Donald Trump than genuine Republicans. These results highlight the potential harms of explicitly listing eligibility requirements and emphasize the importance of minimizing imposter participation. 相似文献

Nat Hansen builds a new argument for subjectivism about the semantics of color language, based on a potential kind of intersubjective disagreements about comparative color statements. In reply, I note that the disagreements of this kind are merely hypothetical, probably few if actual, and not evidently relevant as test cases for a semantic theory. Furthermore, even if they turned out to be actual and semantically relevant, they would be intuitively unusable by the subjectivist. 相似文献

We constantly integrate the information that is available to our various senses. The extent to which the mechanisms of multisensory integration are subject to the influences of attention, emotion, and/or motivation is currently unknown. The ??ventriloquist effect?? is widely assumed to be an automatic crossmodal phenomenon, shifting the perceived location of an auditory stimulus toward a concurrently presented visual stimulus. In the present study, we examined whether audiovisual binding, as indicated by the magnitude of the ventriloquist effect, is influenced by threatening auditory stimuli presented prior to the ventriloquist experiment. Syllables spoken in a fearful voice were presented from one of eight loudspeakers, while syllables spoken in a neutral voice were presented from the other seven locations. Subsequently, participants had to localize pure tones while trying to ignore concurrent visual stimuli (both the auditory and the visual stimuli here were emotionally neutral). A reliable ventriloquist effect was observed. The emotional stimulus manipulation resulted in a reduction of the magnitude of the subsequently measured ventriloquist effect in both hemifields, as compared to a control group exposed to a similar attention-capturing, but nonemotional, manipulation. These results suggest that the emotional system is capable of influencing multisensory binding processes that have heretofore been considered automatic. 相似文献

Under natural conditions, human beings routinely have to choose among multiple alternatives which are associated with specific outcomes of varying desirability. Typically, decisions are based upon the processing of perceptual input, which introduces additional noise to the system. Bayesian decision theory (BDT) allows us to formalize decision under risk and to predict statistically optimal choice behavior. In the present study, human observers performed a classification task characterized by an extensive amount of perceptual uncertainty (auditory localization). In addition, a spatial reward function was imposed on the task. We set up a BDT model with no free parameters to serve as a benchmark for statistically optimal choices, and tested it against a purely perceptual model and a hybrid, heuristic model. In addition, we tested these three models with free rather than fixed parameters for the perceptual uncertainty and the peak of the reward function. The log likelihoods of the models given the empirical data were determined by means of Monte Carlo simulations. Bayesian model comparison (BMC) revealed that the BDT model with two free parameters was the most plausible among the tested models. The fitted parameter values for the peak of the reward function were consistently smaller than the actual peak reward communicated to the participants. The results are discussed in the context of an internal underweighting of the reward function. 相似文献
