Cyber-dehumanization: Violent video game play diminishes our humanity

Across two studies we show that engaging in violent video game play diminishes perceptions of our own human qualities. In addition, when other players are the targets of this violence it reduces our perceptions of their humanity also. In Study 1, we demonstrate that playing Mortal Kombat against another player reduces the perceived humanity of the self as well as the humanity of one's opponent (compared to playing a non-violent game). In Study 2 we replicate this effect on perceived humanity of the self when playing a violent game with a co-player. However, we find no dehumanization of co-players who are not the targets of violence. We demonstrate these effects cannot be reduced to mood, self-esteem, gender, or other characteristics of the game such as excitement and enjoyment. The findings provide a broader perspective from which to view previous work on the adverse effects of violent video games.     

Processing prefixes and suffixes in handwriting production

Previous research showed that handwriting production is mediated by linguistically oriented processing units such as syllables and graphemes. The goal of this study was to investigate whether French adults also activate another kind of unit that is more related to semantics than phonology, namely morphemes. Experiment 1 revealed that letter duration and inter-letter intervals were longer for suffixed words than for pseudo-suffixed words. These results suggest that the handwriting production system chunks the letter components of the root and suffix into morpheme-sized units. Experiment 2 compared the production of prefixed and pseudo-prefixed words. The results did not yield significant differences. This asymmetry between suffix and prefix processing has also been observed in other linguistic tasks. In suffixed words, the suffix would be processed on-line during the production of the root, in an analytic fashion. Prefixed words, in contrast, seem to be processed without decomposition, as pseudo-affixed words.     

Gender Bias Produces Gender Gaps in STEM Engagement

We explored whether the existence of gender bias causes gender gaps in STEM engagement. In Experiment 1 (n?=?322), U.S. women projected less sense of belonging, positivity toward, and aspirations to participate in STEM than did men when exposed to the reality of STEM gender bias. These gender differences disappeared when participants were told that STEM exhibits gender equality, suggesting that gender bias produces STEM gender gaps. Experiment 2 (n?=?429) explored whether results generalized to a specific STEM department, and whether organizational efforts to mitigate gender bias might shrink gender gaps. U.S. women exposed to a biased chemistry department anticipated more discrimination and projected less sense of belonging, positive attitudes and trust and comfort than did men. These gender differences vanished when participants read about an unbiased department, again suggesting that gender bias promotes STEM gender gaps. Further, moderated mediation analyses suggested that in the presence of gender bias (but not gender equality), women projected less positive attitudes and trust and comfort than did men because they experienced less sense of belonging and anticipated more discrimination. Results were largely unaffected by whether departments completed a diversity training, suggesting that knowledge of diversity initiatives alone cannot close STEM gender gaps.     

Reducing gender identity bias through imagined intergroup contact

Transgender individuals face high levels of stereotyping, prejudice, discrimination, and violence. However, there is a paucity of research (particularly experimental work) investigating the magnitude of gender identity bias (GIB) targeting transgender individuals, as well as interventions designed to ameliorate it. To address this gap, we conducted experimental investigations of reactions to identical, highly qualified men or women job applicants described as either transgender or cisgender (Experiments 1a, 1b), and tested the efficacy of an imagined intergroup contact (IIC) intervention (relative to a control condition) in ameliorating GIB against transgender women (Experiment 2). As expected, all applicants were perceived as equally highly competent, adding to the literature suggesting that clearly demonstrating excellent qualifications can prevent biased judgments of candidate competence. However, revealing GIB, transgender men and women were rated as less likeable and hirable than the identical cisgender applicants, despite the fact that they were viewed as equally competent (Experiments 1a, 1b). Providing additional evidence of GIB, in the absence of IIC, participants rated a transgender female applicant as less likeable and hirable than the identical cisgender applicant, and also reported less self‐other overlap and perspective taking for the transgender applicant (Experiment 2). However, these target gender identity differences were reduced (for likeability) or fully eliminated (for the remaining outcomes) in the IIC condition. Put another way, while reactions to the cisgender applicant were unaffected by intervention condition, IIC elevated perceptions of the transgender applicant, suggesting that it may function as an effective GIB intervention.     

Who’s afraid of the big bad wolf? The interweaving of values and science

The role of values in the scientific process is widely debated. But evidence and values cannot be neatly separated. Instead, values infuse the entire scientific process, starting with the choice of research questions. Research avenues are selected based on prior beliefs about the workings of the world. In fact, informally assigned prior probabilities and normalizing constants play an essential role in distinguishing causes from correlations and ignoring irrelevant associations that would otherwise be suggested by raw data. But since these initial probabilities often have a heterogeneous pedigree – often not all that went into their formation is known or knowable – it becomes difficult to cleanly separate evidence from values. At the same time, this reality does not undermine science’s unique status in generating knowledge. This is because it is not the evidence per se generated by science, but rather the method by which science generates it, that justifies science’s privileged role.     

When Practice Does Not Make Perfect: Effects of Strategic Cognitive Processes on Errors During Skill Development

This study looked at the contribution of strategic cognitive processes such as frequency gambling and speed and accuracy trade‐off in the production of errors during skill development. We developed a novel psychomotor task and trained participants on the task. We predicted that practice would change the nature of errors and be driven by strategic processes, rather than just change the overall number of errors. The first experiment investigated the effects of frequency gambling on errors during skill development by manipulating stimulus probability. The second experiment tested the separate effects of speed versus accuracy instructions to clarify the strategic contribution of response‐criterion setting. The results of these two studies refute the widespread assumption that skill development invariably reduces errors. Rather, errors can be a strategic feature of skill acquisition (e.g. gambling on low probability events), which, although results in speedy performance, would be a dangerous practice in many real‐life contexts.

A systematic analysis of distressing near-death experience accounts

ABSTRACT

Near-death experiences (NDEs) are usually associated with positive affect, however, a small proportion are considered distressing. We aimed to look into the proportion of distressing NDEs in a sample of NDE narratives, categorise distressing narratives according to Greyson and Bush’s classification (inverse, void or hellish), and compare distressing and “classical” NDEs. Participants wrote down their experience, completed the Memory Characteristics Questionnaire (assessing the phenomenology of memories) and the Greyson scale (characterising content of NDEs). The proportion of suicidal attempts, content and intensity of distressing and classical NDEs were compared using frequentist and Bayesian statistics. Distressing NDEs represent 14% of our sample (n?=?123). We identified 8 inverse, 8 hellish and 1 void accounts. The proportion of suicide survivors is higher in distressing NDEs as compared to classical ones. Finally, memories of distressing NDEs appear as phenomenologically detailed as classical ones. Distressing NDEs deserve careful consideration to ensure their integration into experiencers’ identity.     

The synergetic principles of nonlinear thinking

In order to develop further the methods of scenario building and to facilitate the paths towards a desirable and sustainable future, we cannot do without a nonlinear evolutionary thinking. The theory of self‐organization of complex systems, called also synergetics, is a scientific basis for such a thinking, the main principles of which are under consideration in the paper. Synergetics provides us with the knowledge of constructive principles of coevolution of complex social systems, coevolution of countries and geopolitical regions being at different stages of development, integration of the East and the West, the North and the South.
