Culture Wars and COVID-19 Conduct: Christian Nationalism,Religiosity, and Americans’ Behavior During the Coronavirus Pandemic

During the COVID-19 pandemic, Americans’ behavioral responses were quickly politicized. Those on the left stressed precautionary behaviors, while those on the (religious) right were more likely to disregard recommended precautions. We propose the far right response was driven less by partisanship or religiosity per se, but rather by an ideology that connects disregard for scientific expertise; a conception of Americans as God's chosen and protected people; distrust for news media; and allegiance to Trump―Christian nationalism. Analyzing panel data collected in the thick of the COVID-19 crisis, we find Christian nationalism was the leading predictor that Americans engaged in incautious behavior like eating in restaurants, visiting family/friends, or gathering with 10+ persons (though not attending church), and was the second strongest predictor that Americans took fewer precautions like wearing a mask or sanitizing/washing one's hands. Religiosity, in contrast, was the leading predictor that Americans engaged in more frequent precautionary behaviors. Findings document that Christian nationalism, not religious commitment per se, undergirded the far-right response to COVID-19 that disregarded precautionary recommendations, thus potentially worsening the pandemic.     

A Restricted Four-Parameter IRT Model: The Dyad Four-Parameter Normal Ogive (Dyad-4PNO) Model

Psychometrika - Recently, there has been a renewed interest in the four-parameter item response theory model as a way to capture guessing and slipping behaviors in responses. Research has shown,...     

The influence of competition and performance goals on decoding complex emotions

Motivation and Emotion - The present research examines the processes through which competitive contexts influence performance in an understudied domain: social perception. In two experiments (one...     

Putting phonetic context effects into context: a commentary on Fowler (2006)

On the basis of a review of the literature and three new experiments, Fowler (2006) concludes that a contrast account for phonetic context effects is not tenable and is inferior to a gestural account. We believe that this conclusion is premature and that it is based on a restricted set of assumptions about a general perceptual account. Here, we briefly address the criticisms of Fowler (2006), with the intent of clarifying what a general auditory and learning approach to speech perception entails.     

Effects of search mode and intertrial priming on singleton search

There is no consensus as to what information guides search for a singleton target. Does the most salient display element capture attention, regardless of the observer's attentional set? Do observers adopt a default salience-based search mode? Does knowledge of the target's defining featural property (when available) affect search? Finally, can intertrial contingencies account for the disparate results in the literature? We investigated search for a shape singleton when (1) the target and nontarget shapes switched unpredictably from trial to trial, (2) the target feature remained fixed, and (3) the target was a singleton on only one third of the trials. We examined overall reaction times, search slopes, errors, and the magnitude of the slowing caused by a cross-dimensional singleton distractor. Our results argue against the idea that search is guided solely by stimulus-driven factors or that subjects adopt a singleton detection mode that is blind to feature information. They show also that intertrial contingencies, although potent, cannot account for the variety of results in the literature.     

English soccer teams' aggressive behavior when playing away from home

Speculation about key factors affecting home advantage still exists. The present study investigated aggressive behavior amongst English Football Premiership (soccer) players and its relation to home advantage. The frequency of aggressive behaviour, identified by the award of a penalty or disciplinary card (yellow for caution or red for dismissal) was analysed over 2000-2003. Chi-square analyses assessed whether a greater frequency of aggressive behavior was performed by teams away from home. In decided matches, teams playing away received significantly more cautions (yellow cards) than home teams. A further analysis of tied matches indicated that away teams received significantly more cautions (yellow cards) than home teams. No significant differences between home and away teams were found for dismissals and penalties awarded. Reasons for these findings are considered.     

Category and letter fluency in semantic dementia, primary progressive aphasia, and Alzheimer's disease

This study examined the impact of various degenerative dementias on access to semantic knowledge and the status of semantic representations. Patients with semantic dementia, primary progressive aphasia, and Alzheimer's disease were compared with elderly controls on tasks of category and letter fluency, with number of words generated, mean lexical frequency and errors recorded. The findings are consistent with the view that category and letter fluency rely on both common and unique cognitive processes. Fluency tasks, with the richness of data obtained, are valuable in distinguishing different dementia syndromes from one another.     

Towards a unified science of cultural evolution

We suggest that human culture exhibits key Darwinian evolutionary properties, and argue that the structure of a science of cultural evolution should share fundamental features with the structure of the science of biological evolution. This latter claim is tested by outlining the methods and approaches employed by the principal subdisciplines of evolutionary biology and assessing whether there is an existing or potential corresponding approach to the study of cultural evolution. Existing approaches within anthropology and archaeology demonstrate a good match with the macroevolutionary methods of systematics, paleobiology, and biogeography, whereas mathematical models derived from population genetics have been successfully developed to study cultural microevolution. Much potential exists for experimental simulations and field studies of cultural microevolution, where there are opportunities to borrow further methods and hypotheses from biology. Potential also exists for the cultural equivalent of molecular genetics in "social cognitive neuroscience," although many fundamental issues have yet to be resolved. It is argued that studying culture within a unifying evolutionary framework has the potential to integrate a number of separate disciplines within the social sciences.
