Puritanism needs purity, and moral psychology needs pluralism.

This account of puritanical morality is useful and innovative, but makes two errors. First, it mischaracterizes the purity foundation as being unrelated to cooperation. Second, it makes the leap from cooperation (broadly construed) to a monist account of moral cognition (as harm or fairness). We show how this leap is both conceptually incoherent and inconsistent with empirical evidence about self-control moralization.

Morality beyond the WEIRD: How the nomological network of morality varies across cultures.

Moral foundations theory has been a generative framework in moral psychology in the last 2 decades. Here, we revisit the theory and develop a new measurement tool, the Moral Foundations Questionnaire-2 (MFQ-2), based on data from 25 populations. We demonstrate empirically that equality and proportionality are distinct moral foundations while retaining the other four existing foundations of care, loyalty, authority, and purity. Three studies were conducted to develop the MFQ-2 and to examine how the nomological network of moral foundations varies across 25 populations. Study 1 (N = 3,360, five populations) specified a refined top-down approach for measurement of moral foundations. Study 2 (N = 3,902, 19 populations) used a variety of methods (e.g., factor analysis, exploratory structural equations model, network psychometrics, alignment measurement equivalence) to provide evidence that the MFQ-2 fares well in terms of reliability and validity across cultural contexts. We also examined population-level, religious, ideological, and gender differences using the new measure. Study 3 (N = 1,410, three populations) provided evidence for convergent validity of the MFQ-2 scores, expanded the nomological network of the six moral foundations, and demonstrated the improved predictive power of the measure compared with the original MFQ. Importantly, our results showed how the nomological network of moral foundations varied across cultural contexts: consistent with a pluralistic view of morality, different foundations were influential in the network of moral foundations depending on cultural context. These studies sharpen the theoretical and methodological resolution of moral foundations theory and provide the field of moral psychology a more accurate instrument for investigating the many ways that moral conflicts and divisions are shaping the modern world.

Difference of cardiac rehabilitation in the morning or evening on indexes of left ventricular and N-terminal pro-brain natriuretic peptide: a randomized controlled trial.

The present study aimed to evaluate the effects a cardiac rehabilitation program (CRP) performed in the morning or evening on left ventricular (LV) filling indices and the level of N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) in patients undergoing percutaneous coronary angioplasty during the COVID-19 pandemic. Methods: This was a randomized controlled single-blinded clinical trial. Ninety-six patients (mean age: 50.2 ± 8.1 years, 36 women and 44 men) with percutaneous coronary angioplasty were divided into two groups of intervention and control. In each group, the CRP was performed in either morning or evening. The CRP included walking and performing push-ups and sit-ups for 8 weeks. The participants of the control groups received routine care. The functional indices of LV, including LV ejection fraction, systolic function, and diastolic function (i.e. the transmitral flow), the E/e' to left atrium peak strain ratio (as an estimation for LA stiffness), and NT-proBNP level were measured in all participants before starting and at the end of the CRP. Results: In the intervention group, the individuals performing the CRP in the evening had significantly higher E-wave (0.76±0.02 vs. 0.75±0.03; P=0.008), ejection fraction (52.5±5.64 vs. 55.5±3.59; P=0.011), and diastolic function velocity (E/A ratio, 1.03±0.06 vs. 1.05±0.03; P=0.014) and significantly lower A-wave (0.72±0.02 vs. 0.71±0.01; P=0.041), E/e' ratio (6.74±0.29 vs. 6.51±0.38; P=0.038), and NT-proBNP level (2007.9±214.24 vs. 1933.9±253.13; P=0.045) compared with those performing the program in the morning. Conclusions: A supervised CRP performed in the evening compared with morning was more effective in improving LV functional indices. Therefore, such home-based interventions are recommended to be performed in the evening during the COVID-19 pandemic.

The Sins of the Parents Are to Be Laid Upon the Children: Biased Humans, Biased Data, Biased Models.

Technological innovations have become a key driver of societal advancements. Nowhere is this more evident than in the field of machine learning (ML), which has developed algorithmic models that shape our decisions, behaviors, and outcomes. These tools have widespread use, in part, because they can synthesize massive amounts of data to make seemingly objective recommendations. Yet, in the past few years, the ML community has been drawing attention to the need for caution when interpreting and using these models. This is because these models are created by humans, from data generated by humans, whose psychology allows for various biases that impact how the models are developed, trained, tested, and interpreted. As psychologists, we thus face a fork in the road: Down the first path, we can continue to use these models without examining and addressing these critical flaws and rely on computer scientists to try to mitigate them. Down the second path, we can turn our expertise in bias toward this growing field, collaborating with computer scientists to reduce the models' deleterious outcomes. This article serves to light the way down the second path by identifying how extant psychological research can help examine and curtail bias in ML models.

The (moral) language of hate.

Humans use language toward hateful ends, inciting violence and genocide, intimidating and denigrating others based on their identity. Despite efforts to better address the language of hate in the public sphere, the psychological processes involved in hateful language remain unclear. In this work, we hypothesize that morality and hate are concomitant in language. In a series of studies, we find evidence in support of this hypothesis using language from a diverse array of contexts, including the use of hateful language in propaganda to inspire genocide (Study 1), hateful slurs as they occur in large text corpora across a multitude of languages (Study 2), and hate speech on social-media platforms (Study 3). In post hoc analyses focusing on particular moral concerns, we found that the type of moral content invoked through hate speech varied by context, with Purity language prominent in hateful propaganda and online hate speech and Loyalty language invoked in hateful slurs across languages. Our findings provide a new psychological lens for understanding hateful language and points to further research into the intersection of morality and hate, with practical implications for mitigating hateful rhetoric online.

The paucity of morality in everyday talk.

Given its centrality in scholarly and popular discourse, morality should be expected to figure prominently in everyday talk. We test this expectation by examining the frequency of moral content in three contexts, using three methods: (a) Participants' subjective frequency estimates (N = 581); (b) Human content analysis of unobtrusively recorded in-person interactions (N = 542 participants; n = 50,961 observations); and (c) Computational content analysis of Facebook posts (N = 3822 participants; n = 111,886 observations). In their self-reports, participants estimated that 21.5% of their interactions touched on morality (Study 1), but objectively, only 4.7% of recorded conversational samples (Study 2) and 2.2% of Facebook posts (Study 3) contained moral content. Collectively, these findings suggest that morality may be far less prominent in everyday life than scholarly and popular discourse, and laypeople, presume.

Moral values predict county-level COVID-19 vaccination rates in the United States.

Despite the widespread availability of COVID-19 vaccines, the United States has a depressed rate of vaccination relative to similar countries. Understanding the psychology of vaccine refusal, particularly the possible sources of variation in vaccine resistance across U.S. subpopulations, can aid in designing effective intervention strategies to increase vaccination across different regions. Here, we demonstrate that county-level moral values (i.e., Care, Fairness, Loyalty, Authority, and Purity) are associated with COVID-19 vaccination rates across 3,106 counties in the contiguous United States. Specifically, in line with our hypothesis, we find that fewer people are vaccinated in counties whose residents prioritize moral concerns about bodily and spiritual purity. Further, we find that stronger endorsements of concerns about Fairness and Loyalty to the group predict higher vaccination rates. These associations are robust after adjusting for structural barriers to vaccination, the demographic makeup of the counties, and their residents' political voting behavior. Our findings have implications for health communication, intervention strategies based on targeted messaging, and our fundamental understanding of the moral psychology of vaccination hesitancy and behavior.

Comparison of the effects of the time of home-based cardiac rehabilitation program on the changes in cardiometabolic risk factors in patients with phase-IV myocardial infarction: A randomized controlled trial.

BACKGROUND: It seems that the time of performing cardiac rehabilitation is important in determining the risk of cardiac complications in patients with myocardial infarction (MI). The present study aimed to investigate the effects of a home-based cardiac rehabilitation program (HCRP) conducted in either the morning or evening on cardiometabolic risk factors in phase IV (maintenance) MI patients. METHODS: In this randomized controlled clinical trial, 80 patients with MI were divided into 2 groups of intervention and control (40 individuals per group). Patients in each group were categorized into morning and evening subgroups (20 individuals per subgroup). The therapeutic regimen in the intervention group included HCRP, routine medications, and exercise and walking programs for 8 weeks. Patients in the control group received routine treatments for 8 weeks. Cardiovascular risk factors comprising of cardiac troponin I (cTnI), mean platelet volume (MPV), C-reactive protein (CRP), and cardiometabolic indicators including cholesterol (Cho), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglyceride (TG), and the maximum rate of oxygen consumption (VO2 max) were measured for all patients before and after the intervention. RESULTS: Our results showed significant reductions in Cho, TG, HDL, LDL, VO2 max, CRP, and MPV (P < 0.05) in the group performing HCRP in the evening compared with the morning group. CONCLUSION: Performing HCRP in the evening, compared with morning, can be significantly more effective in improving the levels of cardiometabolic risk factors in patients with MI. Therefore, it is recommended that rehabilitation programs be implemented in these patients in evening shifts.

Investigating the role of group-based morality in extreme behavioral expressions of prejudice.

Understanding motivations underlying acts of hatred are essential for developing strategies to prevent such extreme behavioral expressions of prejudice (EBEPs) against marginalized groups. In this work, we investigate the motivations underlying EBEPs as a function of moral values. Specifically, we propose EBEPs may often be best understood as morally motivated behaviors grounded in people's moral values and perceptions of moral violations. As evidence, we report five studies that integrate spatial modeling and experimental methods to investigate the relationship between moral values and EBEPs. Our results, from these U.S. based studies, suggest that moral values oriented around group preservation are predictive of the county-level prevalence of hate groups and associated with the belief that extreme behavioral expressions of prejudice against marginalized groups are justified. Additional analyses suggest that the association between group-based moral values and EBEPs against outgroups can be partly explained by the belief that these groups have done something morally wrong.

Moral concerns are differentially observable in language.

Language is a psychologically rich medium for human expression and communication. While language usage has been shown to be a window into various aspects of people's social worlds, including their personality traits and everyday environment, its correspondence to people's moral concerns has yet to be considered. Here, we examine the relationship between language usage and the moral concerns of Care, Fairness, Loyalty, Authority, and Purity as conceptualized by Moral Foundations Theory. We collected Facebook status updates (N = 107,798) from English-speaking participants (n = 2691) along with their responses on the Moral Foundations Questionnaire. Overall, results suggested that self-reported moral concerns may be traced in language usage, though the magnitude of this effect varied considerably among moral concerns. Across a diverse selection of Natural Language Processing methods, Fairness concerns were consistently least correlated with language usage whereas Purity concerns were found to be the most traceable. In exploratory follow-up analyses, each moral concern was found to be differentially related to distinct patterns of relational, emotional, and social language. Our results are the first to relate individual differences in moral concerns to language usage, and to uncover the signatures of moral concerns in language.

The effectiveness of home-based cardiac rehabilitation program on cardiovascular stress indices in men and women with myocardial infarction: a randomised controlled clinical trial / La efectividad del programa de rehabilitación cardíaca domiciliaria sobre los índices de estrés cardiovascular en hombres y mujeres con infarto de miocardio: un ensayo clínico controlado aleatorizado

Abstract Background: cardiac rehabilitation is a structured program to prevent secondary cardiovascular diseases. Objective: to investigate and compare the effectiveness of home-based cardiac rehabilitation program (HBCRP) on improving cardiovascular stress indices in men and women who had experienced myocardial infarction (MI). Methods: in this randomized controlled clinical trial, 80 patients with MI were divided into two groups of intervention and control (n = 40 per group). Analyses were erformed separately in females and males in the both groups. The HBCRP included receiving routine medications along with walking for 8 weeks. The control group only received the routine care along with counseling about having adequate physical activity. Cardiovascular stress indicators including heart rate at rest (HRrest), maximum heart rate (HRmax), recovery heart rate (RHR)at 1 and 2 minutes after the exercise test (i.e. RHR1 and RHR2), systolic and diastolic blood pressures at rest (SBPR and DBPR), and rate pressure product (RPP) were measured by a researcher blinded to the intervention before and after the test. Results: the results showed significant reductions in RHR1 (p<0.001), RHR2 (p<0.01), SBPR (p<0.01), DBPR (p<0.01), and RPP (p<0.001) in both males and females in the intervention group. A significant increase was also observed in HRmax (p<0.001) in the intervention group. However, there were no significant differences in HRmax and other variables comparing per- and post-experiment values in the control group. Conclusion: our results showed that 8 weeks of HBCRP sex-independently reduced cardiovascular stress indices in both men and women with MI.

Resumen Antecedentes: la rehabilitación cardíaca es un programa estructurado para prevenir las enfermedades cardiovasculares secundarias. Objetivo: estudiar y comparar la efectividad de un programa de rehabilitación cardíaca en casa (HBCRP, por sus siglas en inglés) en la mejoría de los índices de estrés cardiovascular en hombres y mujeres que habían sufrido un infarto de miocardio (IM). Métodos: en este ensayo clínico controlado aleatorizado, 80 pacientes con IM se dividieron en dos grupos de intervención y control (n = 40 en cada grupo). Se realizaron análisis por separado en mujeres y hombres en ambos grupos. El HBCRP incluía la administración de medicamentos de rutina junto con caminatas por 8 semanas. El grupo de control solo recibió tratamiento de rutina junto con orientación acerca de la realización de actividad física adecuada. Un investigador cegado a la intervención midió los indicadores de estrés cardiovascular incluyendo frecuencia cardíaca en reposo (FCrep), frecuencia cardíaca máxima (FCmax), recuperación de la frecuencia cardíaca (RFC) 1 y 2 minutos después de la prueba de ejercicio (i.e. RFC1 y RFC2), tensión arterial sistólica y diastólica en reposo (TASR y TADR) y producto frecuencia-presión (PFP), antes y después de la prueba. Resultados: los resultados mostraron una reducción significativa en RFC1 (p<0.001), RFC2 (p<0.01), TASR (p<0.01), TADR (p<0.01), y PFP (p<0.001), tanto en hombres como en mujeres del grupo de intervención. También se observó un aumento significativo en FCmax (p<0.001) en el grupo de intervención. Sin embargo, no hubo diferencias significativas en FCmax y otros variables al comparar los valores pre- y post-experimentales en el grupo control. Conclusión: nuestros resultados mostraron que 8 semanas de HBCRP redujeron los índices de estrés cardiovascular independientemente del sexo, tanto en hombres como en mujeres con IM.

Phosphodiesterase 10A Inhibition Leads to Brain Region-Specific Recovery Based on Stroke Type.

Stroke is the leading cause of adult disability. Recovery of function after stroke involves signaling events that are mediated by cAMP and cGMP pathways, such as axonal sprouting, neurogenesis, and synaptic plasticity. cAMP and cGMP are degraded by phosphodiesterases (PDEs), which are differentially expressed in brain regions. PDE10A is highly expressed in the basal ganglia/striatum. We tested a novel PDE10A inhibitor (TAK-063) for its effects on functional recovery. Stroke was produced in mice in the cortex or the striatum. Behavioral recovery was measured to 9 weeks. Tissue outcome measures included analysis of growth factor levels, angiogenesis, neurogenesis, gliogenesis, and inflammation. TAK-063 improved motor recovery after striatal stroke in a dose-related manner, but not in cortical stroke. Recovery of motor function correlated with increases in striatal brain-derived neurotrophic factor. TAK-063 treatment also increased motor system axonal connections. Stroke affects distinct brain regions, with each comprising different cellular and molecular elements. Inhibition of PDE10A improved recovery of function after striatal but not cortical stroke, consistent with its brain localization. This experiment is the first demonstration of brain region-specific enhanced functional recovery after stroke, and indicates that differential molecular signaling between brain regions can be exploited to improve recovery based on stroke subtype.

Sex differences in moral judgements across 67 countries.

Most of the empirical research on sex differences and cultural variations in morality has relied on within-culture analyses or small-scale cross-cultural data. To further broaden the scientific understanding of sex differences in morality, the current research relies on two international samples to provide the first large-scale examination of sex differences in moral judgements nested within cultures. Using a sample from 67 countries (Study 1; n = 336 691), we found culturally variable sex differences in moral judgements, as conceptualized by Moral Foundations Theory. Women consistently scored higher than men on Care, Fairness, and Purity. By contrast, sex differences in Loyalty and Authority were negligible and highly variable across cultures. Country-level sex differences in moral judgements were also examined in relation to cultural, socioeconomic, and gender-equality indicators revealing that sex differences in moral judgements are larger in individualist, Western, and gender-equal societies. In Study 2 (19 countries; n = 11 969), these results were largely replicated using Bayesian multi-level modelling in a distinct sample. The findings were robust when incorporating cultural non-independence of countries into the models. Specifically, women consistently showed higher concerns for Care, Fairness, and Purity in their moral judgements than did men. Sex differences in moral judgements were larger in individualist and gender-equal societies with more flexible social norms. We discuss the implications of these findings for the ongoing debate about the origin of sex differences and cultural variations in moral judgements as well as theoretical and pragmatic implications for moral and evolutionary psychology.

Do you need a roadmap or can someone give you directions: When school-focused possible identities change so do academic trajectories.

INTRODUCTION: Despite the assumed importance of school-focused possible identities for academic motivation and outcomes, interventions rarely assess the effect of intervention on possible identities. This may be due to difficulty coding open-ended text at scale but leaves open a number of questions: 1) how do school-focused possible identities change over the course of the school year, 2) whether these changes are associated with changes in school outcomes, and 3) whether a machine coding approach is viable. METHODS: In Study 1 (n = 247 Chicago 8th-graders) we assess fall-to-spring change in school-focused possible identities. We test whether change in school-focused possible identities predicts 8th-grade academic outcomes. We include robustness checks. Then we examine school context effects. In Study 2 (n = 1006 Chicago 8th-graders) we address the problem of coding at scale, using a separate data set to train a machine-learning algorithm. RESULTS: On average, school-focused possible identities decline over the school year. But nearly a third of students have increasing school-focused possible identity scores. Increase is associated with improved grades. School context influences whether linked strategies matter. Our machine-learning algorithm accurately classifies school-focused possible identities in our original sample and this school-focused classification reliably predicts academic trajectories. CONCLUSIONS: Change in school-focused possible identities is normative over the course of the school year, interventions should take this into account. On average, students have fewer school-focused possible identities by spring. This decline is associated with declining academic trajectories. However, when school-focused possible identities increase, so do grades. Whether strategies matter is context dependent.

Body Maps of Moral Concerns.

It has been proposed that somatosensory reaction to varied social circumstances results in feelings (i.e., conscious emotional experiences). Here, we present two preregistered studies in which we examined the topographical maps of somatosensory reactions associated with violations of different moral concerns. Specifically, participants in Study 1 (N = 596) were randomly assigned to respond to scenarios involving various moral violations and were asked to draw key aspects of their subjective somatosensory experience on two 48,954-pixel silhouettes. Our results show that body patterns corresponding to different moral violations are felt in different regions of the body depending on whether individuals are classified as liberals or conservatives. We also investigated how individual differences in moral concerns relate to body maps of moral violations. Finally, we used natural-language processing to predict activation in body parts on the basis of the semantic representation of textual stimuli. We replicated these findings in a nationally representative sample in Study 2 (N = 300). Overall, our findings shed light on the complex relationships between moral processes and somatosensory experiences.

The big, the bad, and the ugly: Geographic estimation with flawed psychological data.

The geographic distribution of psychological constructs has long been an area of focus for psychological researchers. Recently, however, there has been increased interest in investigations of the so-called subnational distribution of psychological variables, which focus on localized groupings of individuals within spatial units, such as counties or states. By estimating the subnational distribution of a given outcome (e.g., estimating its state- or county-level means), researchers have been able to address questions about the spatial variation of a variety of psychological constructs and investigate the regional association between psychological phenomena and real-world outcomes, such as health outcomes, prosocial behavior, and racial inequity. Unfortunately, however, there are many challenges to estimating a construct's subnational distribution, such as those raised by response biases and subnational sparsity. To help psychological researchers address these issues, we provide a comprehensive discussion of subnational estimation and introduce multilevel regression and poststratification (MrP), a method that is widely considered to be the gold standard for subnational estimation with random samples. As psychologists often do not have access to large, national random samples, we also report 3 studies evaluating MrP's performance under simulated and real-world conditions of sample biases. Ultimately, we find that MrP is likely to outperform the subnational estimation methods that psychological researchers currently use. Based on this, we suggest that psychologists interested in understanding how psychological phenomena vary below the nation level use MrP to conduct these investigations. To help facilitate this, we have made all code and data used for the reported studies publicly available. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Counterfactual curiosity in preschool children.

We investigated whether young children are curious about what could have been ("counterfactual curiosity"). In two experiments, children aged 4 and 5 years (N = 32 in Experiment 1, N = 24 in Experiment 2) played a matching game in which they turned over cards in the hope that they matched a picture. After choosing a card, children could use "x-ray glasses" to uncover unchosen cards. In Experiment 1, most children spontaneously used the glasses to peek at past alternatives, even when the outcome could no longer be altered. In Experiment 2, children concentrated their information search on alternatives that were within their control. In both experiments, children showed greater interest in counterfactual outcomes when the card they chose turned out not to match the picture. The findings suggest that young children are curious not only about what is but also about what could have been. Curiosity about alternative outcomes seems to precede counterfactual reasoning.

Measuring the importance of context when modeling language comprehension.

It is widely accepted that language requires context in order to function as communication between speakers and listeners. As listeners, we make use of background knowledge - about the speaker, about entities and concepts, about previous utterances - in order to infer the speaker's intended meaning. But even if there is consensus that these sources of information are a necessary component of linguistic communication, it is another matter entirely to provide a thorough, quantitative accounting for context's interaction with language. When does context matter? What kinds of context matter in which kinds of domains? The empirical investigation of these questions is inhibited by a number of factors: the challenge of quantifying language, the boundless combinations of domains and types of context to be measured, and the challenge of selecting and applying a given construct to natural language data. In response to these factors, we introduce and demonstrate a methodological framework for testing the importance of contextual information in inferring speaker intentions from text. We apply Long Short-term Memory (LSTM) networks, a standard for representing language in its natural, sequential state, and conduct a set of experiments for predicting the persuasive intentions of speakers in political debates using different combinations of text and background information about the speaker. We show, in our modeling and discussion, that the proposed framework is suitable for empirically evaluating the manner and magnitude of context's relevance for any number of domains and constructs.
