Categorisation salience and ingroup bias: The buffering role of a multicultural ideology

The current work sought to test the moderating role of a multicultural ideology on the relationship between categorisation salience and ingroup bias. Accordingly, in one experimental study, we manipulated categorisation salience and the accessibility of a multicultural ideology, and measured intergroup attitudes. Results show that categorisation salience only leads to ingroup bias when a multiculturalism (MC) ideology is not made salient. Thus, MC ideology attenuates the negative effects of categorisation salience on ingroup bias. These results pertain to social psychology in general showing that the cognitive processes should be construed within the framework of ideological contexts.     

Individual Differences in Susceptibility to Misinformation Effects and Hindsight Bias

The present study examined individual differences in susceptibility to two similar forms of memory distortion: the misinformation effect and hindsight bias. The misinformation effect occurs when individuals witness an event, are provided with misinformation, and recall the original event as containing elements of the misinformation. Hindsight bias occurs when individuals make judgments, are provided with feedback, and recall their original judgments as being more similar to the feedback than they actually were. Seventy-five participants completed a misinformation task, a hindsight bias task, and several individual difference measures related to memory distortions. Working memory capacity was negatively correlated with the misinformation effect and hindsight bias, and the misinformation effect and hindsight bias were negatively correlated with one another. Although the misinformation effect and hindsight bias are measured with similar designs, and both are predicted by working memory capacity, the negative correlation between them suggests these phenomena result from somewhat different processes.     

Religious Bias Among Religiously Conscious Black Christians in the United States

Research with White participants has demonstrated religious intergroup bias; however, religious identity may be different for Black Americans. Only religiously conscious Black Christians demonstrated a preference for Christian targets over Muslim and Atheist targets. Future research should consider what factors result in a person becoming conscious of other's religion.     

Normative Ethics after Pragmatic Naturalism

Philip Kitcher presents an ambitious account of pragmatic naturalism that incorporates an explanatory story of the emergence and development of ethics, a metaethical perspective on progress, and a normative stance for moral theorizing. This article contends that Kitcher's normative stance is incompatible with the explanatory and metaethical components of his project. Instead, pragmatic naturalists should endorse a normative ethics that is experimental, grounded in practice, and acutely aware of cognitive and informational limitations. In particular, the ethical project would benefit from endorsing empirical work on participatory democracy for the identification of mechanisms to guide us on deep moral conflicts.     

Anxiety and speaking in people who stutter: An investigation using the emotional Stroop task

People with anxiety disorders show an attentional bias towards threat or negative emotion words. This exploratory study examined whether people who stutter (PWS), who can be anxious when speaking, show similar bias and whether reactions to threat words also influence speech motor planning and execution. Comparisons were made between 31 PWS and 31 fluent controls in a modified emotional Stroop task where, depending on a visual cue, participants named the colour of threat and neutral words at either a normal or fast articulation rate. In a manual version of the same task participants pressed the corresponding colour button with either a long or short duration. PWS but not controls were slower to respond to threat words than neutral words, however, this emotionality effect was only evident for verbal responding. Emotionality did not interact with speech rate, but the size of the emotionality effect among PWS did correlate with frequency of stuttering. Results suggest PWS show an attentional bias to threat words similar to that found in people with anxiety disorder. In addition, this bias appears to be contingent on engaging the speech production system as a response modality. No evidence was found to indicate that emotional reactivity during the Stroop task constrains or destabilises, perhaps via arousal mechanisms, speech motor adjustment or execution for PWS.Educational objectives: The reader will be able to: (1) explain the importance of cognitive aspects of anxiety, such as attentional biases, in the possible cause and/or maintenance of anxiety in people who stutter, (2) explain how the emotional Stroop task can be used as a measure of attentional bias to threat information, and (3) evaluate the findings with respect to the relationship between attentional bias to threat information and speech production in people who stutter.

Malleability of weight-biased attitudes and beliefs: A meta-analysis of weight bias reduction interventions

Weight bias exists across many important life domains, necessitating interventions designed to reduce weight-biased attitudes and beliefs. Though the effectiveness of weight bias interventions has been questioned, to our knowledge no meta-analysis of these interventions has been conducted. This meta-analysis evaluated the impact of weight bias interventions on weight-biased attitudes and beliefs and explored potential moderators. Interventions were eligible if they used an adult sample and a validated measure of weight-biased attitudes, which resulted in the inclusion of 30 studies represented in 29 articles. A random effects approach using inverse weights resulted in a mean effect size estimate of g = −0.33 (lower scores indicate less weight bias) for both attitudes and beliefs. Intervention type, publication type, and population type were not significant moderators but demonstrated noteworthy trends. Results reveal a small, positive effect of weight bias interventions on weight-biased attitudes and beliefs and provide useful information for future interventions.     

Object representations are biased toward each other through statistical learning

The visual system is remarkably efficient at extracting regularities from the environment through statistical learning. While such extraction has extensive consequences on cognition, it is unclear how statistical learning shapes the representations of the individual objects that comprise the regularities. Here we examine how statistical learning alters object representations. In three experiments, participants were exposed to either random arrays containing objects in a random order, or structured arrays containing object pairs where two objects appeared next to each other in fixed spatial or temporal configurations. After exposure, one object in each pair was briefly presented and participants judged the location or the orientation of the object without seeing the other object in the pair. We found that when an object reliably appeared next to another object in space, it was judged as being closer to the other object in space even though the other object was never presented (Experiments 1 and 2). Likewise, when an object reliably preceded another object in time, its orientation was biased toward the orientation of the other object even though the other object was never presented (Experiment 3). These results demonstrated that statistical learning fundamentally shapes how individual objects are represented in visual memory, by biasing the representation of one object toward its co-occurring partner. Importantly, participants in all experiments were not explicitly aware of the regularities. Thus, the bias in object representations was implicit. The current study reveals a novel impact of statistical learning on object representation: spatially co-occurring objects are represented as being closer in space, and temporally co-occurring objects are represented as having more similar features.     

Raising the Virtuous Bar: The Underlying Issues of Genetic Moral Enhancement

From the perspective of virtue ethics, is it possible and permissible to enhance moral behavior through gene modification? In preparation to answer this question, we must ask five questions: (1) What may we assume regarding genetic inheritance and human nature? (2) Can specific genes predispose behavior related to the moral virtues? (3) What kind of genetic enhancement would be useful for moral enhancement? (4) Should there be a distinction between somatic and germline gene modification? (5) Is genetic modification best approach to moral enhancement? This article concedes that genetic engineering has the capacity to enhance the human disposition to moral behavior, but gene editing cannot create virtue because virtues are stable, habituated dispositions, acquired over time. That being said, gene editing for purposes of enhancing moral behavior is permissible.
