The second coming of the Ku Klux Klan popularized the Klan and its ideas in the early 1920s, terrorizing Black American, their allies, and others deemed un-American. This article investigates the extent to which the cultural legacy of racial hatred of the Klan has persisted over the years. We use data from large online databases, multiverse analyses, and spatial models to evaluate whether regions with more historical Klan activity show higher levels of modern-day racial bias, and more modern-day White Supremacist activity.

Article Synopsis
  • Discrimination in evaluations contributes significantly to social inequality, yet there is limited knowledge about psychological interventions to combat biased assessments.
  • A research contest tested 30 interventions aimed at reducing discrimination based on physical attractiveness, revealing two effective strategies that reduced both decision noise and bias.
  • The findings highlight the need for concrete strategies that focus on relevant criteria in decision-making and emphasize the challenge of developing scalable interventions to effectively change discriminatory behaviors across various contexts.

The 2020 Black Lives Matter (BLM) protests in response to the murder of George Floyd highlighted the lingering structural inequalities faced by Black people in the United States. In the present research, we investigated whether these protests led to reduced implicit and explicit racial bias among White U.S.

The harm-made mind phenomenon implies that witnessing intentional harm towards agents with ambiguous minds, such as robots, leads to augmented mind perception in these agents. We conducted two replications of previous work on this effect and extended it by testing if robots that detect and simulate emotions elicit a stronger harm-made mind effect than robots that do not. Additionally, we explored if someone is perceived as less prosocial when harming a robot compared to treating it kindly.

Collaborations may sometimes increase the likelihood of engaging in dishonest behaviour. As yet, it remains unknown what factors contribute to this phenomenon. Here, we investigate whether it matters with whom people are collaborating for the extent to which they are dishonest.

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments.

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g.

Face masks are now worn frequently to reduce the spreading of the SARS-CoV-2 virus. Their health benefits are undisputable, but covering the lower half of one's face also makes it harder for others to recognize facial expressions of emotions. Three experiments were conducted to determine how strongly the recognition of different facial expressions is impaired by masks, and which emotions are confused with each other.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation.

Recent evidence shows that body context may alter the categorization of facial expressions. However, less is known about how facial expressions influence the categorization of emotional bodies. We hypothesized that context effects would be displayed bidirectionally, from bodies to faces and from faces to bodies.

Facial expressions play a central role in diverse areas of psychology. However, facial stimuli are often only validated by adults, and there are no face databases validated by school-aged children. Validation by children is important because children still develop emotion recognition skills and may have different perceptions than adults.

Across two studies majority group children's (8-13 years) perception of positive and negative emotions in ethnic in-group and disadvantaged ethnic out-group peers was examined. Study 1 ( = 302) showed that children expected in-group peers to feel better in a positive situation compared to out-group peers. Whereas, in a negative situation, children expected in-group peers to feel less bad compared to out-group peers, particularly when they evaluated the in-group as very positive.

Recently, Cognition and Emotion published an article demonstrating that age cues affect the speed and accuracy of emotion recognition. The authors claimed that the observed effect of target age on emotion recognition is better explained by evaluative than stereotype associations. Although we agree with their conclusion, we believe that with the research method the authors employed, it was impossible to detect a stereotype effect to begin with.

Most research on emotion recognition focuses on facial expressions. However, people communicate emotional information through bodily cues as well. Prior research on facial expressions has demonstrated that emotion recognition is modulated by top-down processes.

Two studies examined when and why children (10-13 years) help ethnic in-group and out-group peers. In Study 1 (n = 163) children could help an out-group or in-group peer with a word-guessing game by entering codes into a computer. While children evaluated the out-group more negatively than the in-group, they helped out-group peers more than in-group peers.

We investigated whether stereotype associations between specific emotional expressions and social categories underlie stereotypic emotion recognition biases. Across two studies, we replicated previously documented stereotype biases in emotion recognition using both dynamic (Study 1) and static (Study 2) expression displays. Stereotype consistent expressions were more quickly decoded than stereotype inconsistent expression on Moroccan and White male faces.
