Large environmental changes reduce valence-dependent belief updating.

When updating beliefs, humans tend to integrate more desirable information than undesirable information. In stable environments (low uncertainty and high predictability), this asymmetry favors motivation towards action and perceived self-efficacy. However, in changing environments (high uncertainty and low predictability), this process can lead to risk underestimation and increase unwanted costs. Here, we examine how people (n = 388) integrate threatening information during an abrupt environmental change (mandatory quarantine during the COVID-19 pandemic). Given that anxiety levels are associated with the magnitude of the updating belief asymmetry; we explore its relationship during this particular context. We report a significant reduction in asymmetrical belief updating during a large environmental change as individuals integrated desirable and undesirable information to the same extent. Moreover, this result was supported by computational modeling of the belief update task. However, we found that the reduction in asymmetrical belief updating was not homogeneous among people with different levels of Trait-anxiety. Individuals with higher levels of Trait-anxiety maintained a valence-dependent updating, as it occurs in stable environments. On the other hand, updating behavior was not associated with acute anxiety (State-Anxiety), health concerns (Health-Anxiety), or having positive expectations (Trait-Optimism). These results suggest that highly uncertain environments can generate adaptive changes in information integration. At the same time, it reveals the vulnerabilities of individuals with higher levels of anxiety to adapt the way they learn.

Trajectories of positive attributes from childhood to young adulthood and its associations with threat and deprivation.

OBJECTIVE: The aims of this study are to investigate the trajectory of positive attributes from childhood to early adulthood and to explore how those trajectories can be modified by two domains of childhood adversity - threat and deprivation. METHODS: A large prospective school-based community cohort of youths (n=2,511, 6-14 years of age, 45% female) was assessed and followed up for 3 years (80% retention) and 6 years (71% retention). Positive attributes were assessed by the Youth Strength Inventory (YSI). Childhood exposure to threat and deprivation were assessed by a composite measure using multiple indicators. RESULTS: Trajectories of YSI scores were non-linear and distinct for boys and girls. While boys presented a more stable trajectory; girls showed higher levels of positive attributes early in life that decrease over time around adolescence. Both exposure to threat and deprivation presented negative linear association with YSI over time. Furthermore, we found interactions between developmental stage and both adversity domains meaning that the effects of exposure to adversity were stronger at earlier developmental stages and almost non-significant closer to early adulthood. CONCLUSION: Our findings provide new evidence on trajectories of positive attributes in youth and reveal and how experiences of adversity in early life impact not only mental disorder but also positive aspects of mental health.

Conspiring under threats! An investigation of associations between COVID-19 health and economic threats and conspiracy beliefs in Italy and Argentina.

Theory and research suggest that threats aroused by a given crisis lead to conspiracy beliefs. Although crises involve the arise of multiple threats (e.g., economic, safety, etc.) diversely affecting various needs and outcomes (i.e., cognition, emotion and behaviour), no research has yet focused on specific relations that different threats may have with the endorsement of conspiracy beliefs. In this study, we distinguished between health and economic threats aroused by the COVID-19 pandemic, and we tested their associations with conspiracy beliefs. Findings from two correlational studies conducted in Italy and Argentina showed that while COVID-19's economic threat was positively and consistently related to conspiracy beliefs, the relationship between COVID-19's health threat and conspiracy beliefs was negative and significant in the Italian sample and non-significant in the Argentinian sample. Results are discussed within the context of the effects of multiple threats elicited by crises on conspiracy beliefs.

Trajectories of positive attributes from childhood to early adulthood and their association with environmental factors

Objective: To investigate the trajectory of positive attributes from childhood to early adulthood and how these trajectories might be modified by environmental factors. Methods: We enrolled 2,511 participants aged 6 to 14 years from a large prospective school-based community cohort of Brazilian children and adolescents, 45% of whom were girls. They were assessed and followed for up to 3 years (with 80% retention) or 6 years (with 71% retention). Positive attributes were assessed by using the Youth Strength Inventory (YSI). A composite measure using several indicators was used to assess childhood exposure to threats and deprivations. Results: The trajectories of YSI scores were nonlinear for male and female participants, being high in childhood, decreasing in adolescence, and being high again in early adulthood. Exposure to threat and deprivation presented a negative linear association with YSI over time. Furthermore, exposure to threat and deprivation early in life, but not later, presented an additional effect on decreasing positive attributes during the life course. Conclusion: Our findings provide new evidence on the trajectories of positive attributes in children and adolescents and show how early life adversity affects not only mental disorders but also positive aspects of mental health.

The great pretenders? Individuals' responses to threats to their remote worker identities.

Introduction: This study aims to understand (a) how remote workers respond to threats to their identity and (b) the conditions in which each coping response tends to occur more frequently. Methods: To this end, we pursued a grounded theory approach, conducting interviews with 71 individuals who chose to work remotely. Results: Our model and theoretical propositions create insights into how remote workers respond to negative stigma from a range of origins. While some responses lead to restructuring the remote workers' identity (identity restructuring responses), others involve keeping the enactment of such identity (identity-preserving responses) or maintaining a paradoxical relationship between restructuring and preserving the identity (paradoxical identity work responses). We also theorise on the conditions under which each response is more likely to occur. Discussion: We expand the predominant focus on the meso and macro aspects of this type of work to the micro-interactions in which these individuals engage, thus highlighting how identity is made, performed, created, and enacted, within specific boundary conditions. In addition, by reflecting upon remote workers' identity threats in light of the wider macro context. We also explore the conditions under which specific kinds of responses tend to emerge.

High vulnerability of coastal wetlands in Chile at multiple scales derived from climate change, urbanization, and exotic forest plantations.

Coastal wetlands are considered one of the most vulnerable ecosystems worldwide; the ecosystem services they provide and the conservation of their biodiversity are threatened. Despite the high ecological and socioenvironmental value of coastal wetlands, regional and national vulnerability assessments are scarce. In this study we aimed to assess the vulnerability of coastal wetlands in Chile from 18°S to 42°S (n = 757) under a multiscale approach that included drivers associated with climate change and land cover change. We assessed multiple drivers of vulnerability at three spatial scales (10 m, 100 m, and 500 m) by analyzing multiple remote sensing data (16 variables) on land cover change, wildfires, climatic variables, vegetation functional properties, water surface and importance for biodiversity. We constructed a multifactorial vulnerability index based on the variables analyzed, which provided a map of coastal wetland vulnerability. Then we explored the main drivers associated with the vulnerability of each coastal wetland by performing a Principal Components Analysis with Agglomerative Hierarchical Clustering, which allowed us to group coastal wetlands according to the drivers analyzed. We found that 42.6 ± 9.2 % of the coastal wetlands evaluated have high or very high vulnerability, with higher vulnerability at the 500 m scale (51.4 %). We identified four groups of coastal wetlands: two located in central Chile, mainly affected by climate change-associated drivers (41.9 ± 2.1 %), and one in central Chile which is affected by land cover change (52.8 ± 6.2 %); the latter has a lower vulnerability level. The most vulnerable coastal wetlands were located in central Chile. Our results present novel findings about the current vulnerability of coastal wetlands, which could be validated by governmental institutions in field campaigns. Finally, we believe that our methodological approach could be useful to generate similar assessments in other world zones.

The occurrence of emerging compounds in real urban wastewater before and after the COVID-19 pandemic in Cali, Colombia.

The COVID-19 pandemic is considered one of the most significant global disasters in the last years. The rapid increase in infections, deaths, treatment, and the vaccination process has resulted in the excessive use of pharmaceuticals that have entered the environment as micropollutants. Considering the prior information about the presence of pharmaceuticals found in the wastewater of Cali, Colombia, which was collected from 2015 to 2022. The data monitored after the COVID-19 pandemic showed an increase in the concentration of analgesics and anti-inflammatory drugs of up to 91%. This increase was associated with the consumption of pharmaceuticals for mild symptoms, such as fever and pain. Moreover, the increase in concentration of pharmaceuticals poses a highly ecological threat, which was up to 14 times higher than that reported before of COVID-19 pandemic. These results showed that the COVID-19 had not only impacted human health but also had an effect on environmental health.

Oxidative damage in the Vesper mouse (Calomys laucha) exposed to a simulated oil spill-a multi-organ study.

Small wild mammals have been used to measure the damage caused by exposure to oil-contaminated soil, including deer mice. However, the study of toxic effects of crude oil using oxidative damage biomarkers in the wild rodent Calomys laucha (Vesper mouse) is absent. This investigation aimed to evaluate the effects of acute exposure to contaminated soil with different concentrations of crude oil (0, 1, 2, 4 and 8% w/w), simulating an accidental spill, using oxidative stress biomarkers in the liver, kidneys, lungs, testes, paw muscle, and lymphocytes of C. laucha. Animals exposed to the contaminated soil showed increases in lipid peroxidation and protein carbonylation at the highest exposure concentrations in most organ homogenates analyzed and also in blood cells, but responses to total antioxidant capacity were tissue-dependent. These results showed that acute exposure to oil-contaminated soil caused oxidative damage in C. laucha and indicate these small mammals may be susceptible to suffer the impacts of such contamination in its occurrence region, threatening the species' survival.

Validity and reliability of the Chinese version of Threats of Artificial Intelligence Scale (TAI) in Chinese adults.

With the outbreak of the COVID-19 pandemic, artificial intelligence (AI) has been widely used in fields such as medical treatment, while the threat of artificial intelligence has also received extensive attention. However, this topic has been only limitedly explored in China. To provide a measurement tool for AI threat research in China, this study aimed to examine the validity and reliability of the Threats of Artificial Intelligence Scale (TAI) in two Chinese samples of adults (N1 = 654, N2 = 1483). Results of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) suggested that the one-factor model of TAI as the best fitting model. Furthermore, the Chinese TAI was significantly related to Positive and Negative Affect Scale and Self-Rating Anxiety Scale, proving good criterion-related validity of the Chinese TAI. In sum, this study suggested the Chinese version of the TAI as a reliable and effective tool in assessing AI threat in the Chinese context. Limitations and future directions are discussed.

Gender Stereotype Threat Undermines Dance Performance and Learning in Boys.

The objective of the present study was to examine the effects of gender stereotype on the performance and learning of a classical ballet pirouette in 11-year-old boys. Participants in the stereotype threat (ST) group were informed that, in general, boys tend to show worse results when completing the pirouette task in comparison to girls. Participants in the stereotype lift (SL) group were told that girls tend to show worse results in comparison to boys. The control group did not receive stereotype instructions. The results demonstrated worse performance during practice and retention (next day) for the ST group relative to the SL and control groups; the SL and control groups did not differ. The findings indicate that gender stereotype threat can undermine motor performance and learning in boys.

Threat and deprivation are associated with distinct aspects of cognition, emotional processing, and psychopathology in children and adolescents.

Exposure to childhood adversity has been consistently associated with poor developmental outcomes, but it is unclear whether these associations vary across different forms of adversity. We examined cross-sectional and longitudinal associations between threat and deprivation with cognition, emotional processing, and psychopathology in a middle-income country. The sample consisted of 2511 children and adolescents (6-17 years old) from the Brazilian High-Risk Cohort for Mental Conditions. Parent reports on childhood adversity were used to construct adversity latent constructs. Psychopathology was measured by the Child Behavior Checklist (CBCL) to generate a measure of general psychopathology (the "p" factor). Executive function (EF) and attention orienting toward angry faces were assessed using cognitive tasks. All measures were acquired at two time-points 3 years apart and associations were tested using general linear models. Higher levels of psychopathology were predicted by higher levels of threat cross-sectionally and longitudinally, and by deprivation longitudinally. For EF, worse performance was associated only with deprivation at baseline and follow-up. Finally, threat was associated with attention orienting towards angry faces cross-sectionally, but neither form of adversity was associated with changes over time in attention bias. Our results suggest that threat and deprivation have differential associations with cognitive development and psychopathology. Exposure to adversity during childhood is a complex phenomenon with meaningful influences on child development. Because adversity can take many forms, dimensional models might help to disentangle the specific developmental correlates of different types of early experience.

Expressões de homofobia e conflito intergrupal entre fãs de league of legends / Expressions of homophobia and intergroup conflict between league of legends fans / Expresiones de homofobia y conflicto intergrupal entre aficionados de league of legends

Os jogos digitais são considerados um ambiente de privilégio masculino que exalta o padrão heteronormativo de masculinidade. A partir da Teoria das Representações Sociais, buscamos identificar as diferentes formas de expressão e ancoragens da homofobia a partir de princípios organizadores, nos discursos dos fãs do jogo League of Legends (LoL) na rede social Facebook. Foram selecionados 470 comentários publicados em 2017, os quais foram analisados com apoio do Iramuteq (software de análise lexicométrica) por meio de uma classificação hierárquica descendente, resultando em quatro classes: "Debate sobre a sexualidade dos campeões" (14,9%), "Representatividade no LoL" (29,8%), "Confronto entre as histórias de Varus" (39%), e "Estratégia empresarial" (16,2%). Os resultados evidenciam a existência de um conflito intergrupal, mediado pelo processo de ameaça simbólica: enquanto alguns comentários, realizados majoritariamente por homens heterossexuais, se utilizam do preconceito sutil para perpetuar a manutenção da heteronormatividade, outros comentários reforçam a importância da representação da diversidade nos jogos digitais.(AU)

Digital games are considered an environment of male privilege that promotes heteronormative standard of masculinity. Based on the Theory of Social Representations, we seek to identify, based on organizing principles, the forms of expression and anchorages processes related to homophobia within the speeches of the fans of the game League of Legends (LoL), on Facebook. A total of 470 comments published in 2017 were selected to be then analyzed with support from IRAMUTEQ software (lexicometric analysis software), which resulted in four classes: "Debate on the sexuality of champions" (14.9%), "Representativeness in LoL" (29.8%), "Confrontation between the stories of Varus" (39%), and "Business strategy" (16.2%). The results show intergroup conflict that is mediated by the process of symbolic threat: some comments, which are mostly from heterosexual men, carry aspects of covert prejudice to perpetuate the maintenance of heteronormative standards, whereas other comments reinforce the importance of representing diversity in digital games.(AU)

Análisis bifactorial y validez de constructo de la Escala de Percepción de Amenaza exogrupal frente a los inmigrantes VIH positivos en una muestra de adultos peruanos / Bifactorial analysis and construct validity of the Out-group Threat Perception Scale against HIV-positive immigrants in a sample of Peruvian adults

En la actualidad se evidenciado aumento de los desplazamientos provocados por conflictos, persecuciones, falta de oportunidades, seguridad, entre otras razones, inscrementando la población de migrante en países de América Latina. Se destaca los desplazados venezolanos, siendo Perú el segundo país de Latinoamérica con más de esta población de migrantes. Estudios han alertado sobre la desvalorización de los migrantes y especialmente aquellos que vivan con enfermedades infectocontagiosas como es el VIH. Los ciudadanos autóctonos del país receptor, percirbe la presencia del exogrupo como amenazas a sus derechos sociales relacionándose con actitudes negativas, que se ha ido poteciando por los medios de comunicación. Por tanto, es importante realizar estudios que estimen el discernimiento de amenazas exogrupal estrechamente hacia los migrantes. El objetivo evaluar las evidencias psicométricas del instrumento de medición EPAE en una muestra de adultos peruanos frente a los inmigrantes VIH. El análisis de los ítems y de confiabilidad demostró un adecuado funcionamiento a excepción de los ítems 4, 5, 11 y 12. Se propone utilizar el modelo 2, el cual consta de 9 agregados, confirmado por los diferentes índices estadísticos (X2/gl=3.49; WMRM=1.124; NFI=0.993; CFI=0.995; GFI=0.997; RMSEA=0.045; SRMR=0.035). Según los valores del análisis bifactor no existe suficiente evidencia para asumir un factor general, se recomienda trabajar con dimensiones independientes. Es importante la identificación de percepción de amenazas reales, debido a que investigaciones han evidenciado que el estigma asociado con el VIH constituye uno de los mayores obstáculos para la prevención de nuevas infecciones(AU)

Currently, there is evidence of an increase in displacement caused by conflicts, persecution, lack of opportunities, security, among other reasons, increasing the migrant population in Latin American countries. The displaced Venezuelans stand out, with Peru being the second country in Latin America with more than this population of migrants. Studies have warned about the devaluation of migrants and especially those who live with infectious diseases such as HIV. The autochthonous citizens of the receiving country perceive the presence of the outgroup as threats to their social rights, related to negative attitudes, which has been promoted by the media. Therefore, it is important to carry out studies that estimate the discernment of out-group threats closely towards migrants. The objective is to evaluate the psychometric evidence of the EPAE measurement instrument in a sample of Peruvian adults compared to HIV immigrants. The analysis of the items and reliability showed an adequate functioning with the exception of items 4, 5, 11 and 12. It is proposed to use model 2, which consists of 9 aggregates, confirmed by the different statistical indices (X2/df= 3.49; WMRM=1.124; NFI=0.993; CFI=0.995; GFI=0.997; RMSEA=0.045; SRMR=0.035). Given the values of the bifactor analysis, there is not enough evidence to assume a general factor, it is recommended to work with independent dimensions. It is important to identify the perception of real threats, since research has shown that the stigma associated with HIV constitutes one of the greatest obstacles to the prevention of new infections(AU)

Cannabidiol impairs fear memory reconsolidation in female rats through dorsal hippocampus CB1 but not CB2 receptor interaction.

Women present increased susceptibility to anxiety- and stress-related disorders compared to men. A potentially promising pharmacological-based strategy to regulate abnormal aversive memories disrupts their reconsolidation stage after reactivation and destabilization. Male rodent findings indicate that cannabidiol (CBD), a relatively safe and effective treatment for several mental health conditions, can impair the reconsolidation of aversive memories. However, whether and how CBD influences it in females is still unknown. The present study addressed this question in contextually fear-conditioned female rats. We report that systemically administered CBD impaired their reconsolidation, reducing freezing expression for over a week. This action was restricted to a time when the reconsolidation presumably lasted (< six hours post-retrieval) and depended on memory reactivation/destabilization. Moreover, the impairing effects of CBD on memory reconsolidation relied on the activation of cannabinoid type-1 but not type-2 receptors located in the CA1 subregion of the dorsal hippocampus. CBD applied directly to this brain area was sufficient to reproduce the effects of systemic CBD treatment. Contextual fear memories attenuated by CBD did not show reinstatement, an extinction-related feature. By demonstrating that destabilized fear memories are sensitive to CBD and how it hinders mechanisms in the DH CA1 that may restabilize them in female rats, the present findings concur that reconsolidation blockers are viable and could be effective in disrupting abnormally persistent and distressing aversive memories such as those related to posttraumatic stress disorder.

Highly Demand Working Memory Intervention Weakens a Reactivated Threat Memory and the Associated Cognitive Biases.

Anxiety disorders are the most frequent type of mental disorder. Threat-conditioning memory plays a central role in anxiety disorders, impacting complex cognitive systems by modifying behavioral responses to fearful stimuli and inducing an overestimation of potential threats. Here, we analyzed the reminder-dependent amnesia on physiological responses, unconditioned stimulus (US) expectancy ratings, and measures of cognitive bias towards the threat of a threat-conditioning memory. Subjects received differential threat-conditioning. Twenty-four hours later, after reactivation of the memory of threat-conditioning, one group performed a high demand working memory task (HWM) and a second group a low demand working memory task (LWM). A third group only performed the HWM task. Retention of conditioned threat memory was tested on Day 3 in an extinction session followed by a reinstatement test. Tasks targeting stimulus representation, valuation, and attentional bias towards threat were performed. We show that the reminder-dependent intervention with an HWM weakened memory retention as expressed in skin conductance response (SCR) and faded the representation and valuation towards the threat, but it did not affect US expectancy or attentional bias. Our findings provide evidence for the experimental psychopathology approach opening the possibility to weaken both Threat conditioning memory and the systems associated with the maintenance of anxiety features.

Alpha-band EEG suppression as a neural marker of sustained attentional engagement to conditioned threat stimuli.

Attention helps us to be aware of the external world, and this may be especially important when a threat stimulus predicts an aversive outcome. Electroencephalogram (EEG) alpha-band suppression has long been considered as a neural signature of attentional engagement. The present study was designed to test whether attentional engagement, as indexed by alpha-band suppression, is increased in a sustained manner following a conditioned stimulus (CS) that is paired with an aversive (CS+) vs neutral (CS-) outcome. We tested 70 healthy young adults in aversive conditioning and extinction paradigms. One of three colored circles served as the CS+, which was paired in 50% of the trials with a noise burst (unconditioned stimulus, US). The other colored circles (CS-) were never paired with the US. For conditioning, we found greater alpha-band suppression for the CS+ compared to the CS-; this suppression was sustained through the time of the predicted US. This effect was significantly reduced for extinction. These results indicate that conditioned threat stimuli trigger an increase in attentional engagement as subjects monitor the environment for the predicted aversive stimulus. Moreover, this alpha-band suppression effect may be valuable for future studies examining normal or pathological increases in attentional monitoring following threat stimuli.

Effects of Gender Stereotypes on Balance Performance and Learning in Men.

The purpose of this study was to examine the effects of gender stereotypes on the performance and learning of a balance task in men. Before practice, forty-eight participants received instructions involving the comparison of balance between males and females: males normally perform worse than females (stereotype threat condition - ST), females usually perform worse than males (stereotype lift condition - SL), or no instructions regarding gender stereotypes (control condition). One day later, they performed a retention test. The results show that the SL group outperformed the other groups during practice, but not retention. ST participants reported lower perceived competence. The findings show that gender stereotypes can affect perceptions of competence and balance performance, but not balance learning, in men.
