Metagenomic perspectives on antibiotic resistance genes in tap water: The environmental characteristic, potential mobility and health threat.

As an emerging environmental contaminant, antibiotic resistance genes (ARGs) in tap water have attracted great attention. Although studies have provided ARG profiles in tap water, research on their abundance levels, composition characteristics, and potential threat is still insufficient. Here, 9 household tap water samples were collected from the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) in China. Additionally, 75 sets of environmental sample data (9 types) were downloaded from the public database. Metagenomics was then performed to explore the differences in the abundance and composition of ARGs. 221 ARG subtypes consisting of 17 types were detected in tap water. Although the ARG abundance in tap water was not significantly different from that found in drinking water plants and reservoirs, their composition varied. In tap water samples, the three most abundant classes of resistance genes were multidrug, fosfomycin and MLS (macrolide-lincosamide-streptogramin) ARGs, and their corresponding subtypes ompR, fosX and macB were also the most abundant ARG subtypes. Regarding the potential mobility, vanS had the highest abundance on plasmids and viruses, but the absence of key genes rendered resistance to vancomycin ineffective. Generally, the majority of ARGs present in tap water were those that have not been assessed and are currently not listed as high-threat level ARG families based on the World Health Organization Guideline. Although the current potential threat to human health posed by ARGs in tap water is limited, with persistent transfer and accumulation, especially in pathogens, the potential danger to human health posed by ARGs should not be ignored.

Ambiguity potentiates effects of loneliness on feelings of rejection.

For social species, having strong and high-quality social relationships is an important safety cue. Loneliness occurs when an individual perceives they have insufficient relationships resulting in feelings of lack of safety. States of perceived unsafety are linked to an increased tendency to construe ambiguous information - information lacking a unique clear interpretation - as threatening. Here, we explore whether the ambiguity of social cues of interpersonal rejection moderates effects of loneliness on feelings of rejection while undergoing social exclusion. Data were collected in 2021; 144 adults completed a progressive social exclusion paradigm where they were randomly assigned to be equally included, excluded, or over-included. Social exclusion/inclusion cues became more pronounced over the course of multiple rounds of a ball-tossing game (Cyberball) resulting in a scenario where ambiguity was highest in earlier rounds and decreased over time. Participants reported feelings of loneliness prior to the task and feelings of rejection throughout the task. Results demonstrated that higher loneliness predicted increased feelings of rejection regardless of exclusion condition. Notably, this positive relationship was strongest during earlier rounds when social cues were most ambiguous. These findings contribute to our understanding of how loneliness modulates social perception to enable organisms to adequately adapt to changing circumstances.

Explaining post-traumatic stress symptoms and sleep disturbance in Ukrainian civilians: perceived threat versus objective war exposure.

Objective: This study investigated the impact of war exposure on post-traumatic stress symptoms (PTSS) and sleep disturbance across Ukraine. Subjective and objective indicators of war exposure were modelled as predictors of these symptoms.Methods: We created two predictors: first, we used governmental and crowd-sourced data to create an objective war exposure index for each of the 21 non-occupied regions of Ukraine, based on the number of air raid alarms, explosions, and proximity to frontline; and second, we obtained self-report cross-sectional data, using convenience sampling, from a nation-wide survey (N = 991) on subjective experience of threat triggered by the war. The survey also measured the outcome variables of PTSS and sleep disturbance. Hierarchical multilevel regressions modelled the relationship of this objective war exposure index with the two outcome variables, after accounting for demographics. A final regression step modelled subjective threat as predictor of these symptoms.Results: We observed strongly elevated levels of PTSS and sleep disturbance and strong regional differences in objective and subjective war indicators. Objective war exposure predicted PTSS but not sleep disturbance, whereas subjective threat predicted both symptom domains.Conclusion: The study demonstrates the utility of objective war exposure data for predicting the prevalence of PTSS in the different regions. The results further underscore the prominent role of subjective appraisal processes in the symptomatology of PTSS and sleep disturbance, thus informing theories on trauma-related disorders. Our results can guide the allocation of mental health services by identifying highly affected regions.

Objective data on air raid alarms and explosions have been prospectively collected in Ukraine.We related those objective data to symptom reports of 991 responders in most Ukraine regions.Objective data explained symptoms of post-traumatic stress but not sleep disturbance.

Holocaust centrality, anxiety, and other risk factors associated with terror threat salience among descendants of Holocaust survivors.

The study examined risk factors for sensitivity to terror threats among descendants of Holocaust survivors (Holocaust G1) during a significant rise in terrorist attacks in Israel. We examined the association of the number of familial Holocaust G1, trauma exposure, probable posttraumatic stress disorder (PTSD), anxiety symptoms, and Holocaust centrality with terror threat salience (TTS) in children and grandchildren of Holocaust G1 (Holocaust G2; G3). A web-based national sample included 297 Holocaust G2 (Mage=62.95, SD=10.25), 224 comparison G2 (Mage=61.79, SD=10.13), 379 Holocaust G3 (Mage=34.02, SD=8.65) and 171 comparison G3 (Mage=33.55, SD=8.26). Participants completed questionnaires on background characteristics, Holocaust background, trauma exposure, probable PTSD, anxiety symptoms, Holocaust centrality, and TTS. Findings showed that Holocaust G2 and G3 reported higher Holocaust centrality and TTS relative to comparisons, and Holocaust G3 reported higher levels of anxiety than comparison G3. The number of Holocaust G1, background characteristics, Holocaust centrality, and anxiety symptoms were associated with TTS in G2 and G3. Probable PTSD and trauma exposure were also associated with TTS in G2 and G3, respectively. Results highlight Holocaust centrality and anxiety among the factors associated with an increased preoccupation with terror threats in Holocaust descendants. Practitioners should implement interventions focusing on these factors, particularly at times of increased terrorism.

Elicitation of security threats and vulnerabilities in Insurance chatbots using STRIDE.

Although chatbots are used a lot for customer relationship management (CRM), there needs to be more data security and privacy control strategies in chatbots, which has become a security concern for financial services institutions. Chatbots gain access to large amounts of vital company information and clients' personal information, which makes them a target of security attacks. The loss of data stored in chatbots can cause major harm to companies and customers. In this study, STRIDE (viz. Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, Elevation of privilege) modelling was applied to identify the data security vulnerabilities and threats that pertain to chatbots used in the insurance industry. To do this, we conducted a case study of a South African insurance organisation. The adopted methodology involved data collection from stakeholders in the insurance organisation to identify chatbot use cases and understand chatbot operations. After that, we conducted a STRIDE-based analysis of the chatbot use cases to elicit security threats and vulnerabilities in the insurance chatbots in the organisation. The results reveal that security vulnerabilities associated with Spoofing, Denial of Service, and Elevation of privilege are more relevant to insurance chatbots. The most security threats stem from Tampering, Elevation of privilege, and Spoofing. The study extends the discussion on chatbot security. It fosters an understanding of security threats and vulnerabilities that pertain to insurance chatbots, which is beneficial for security researchers and practitioners working on the security of chatbots and the insurance industry.

Openness to experience, a personality trait that reduces susceptibility to memory age-based stereotype threat.

Introduction: Age-based stereotype threat (ABST), the concern of being judged according to a negative age stereotype may lead to underperformance in the stereotype domain. The present study aims to replicate the negative effect of ABST on episodic memory. Importantly, we further examine openness to experience as a potential buffer of the ABST effect as well as the role that different memory strategies may play in episodic memory performance. Method: Seventy-five older adults were randomly assigned to the ABST condition or the control condition before taking a word-stem cued recall memory task. They learned word-lists with either a repetition strategy, low resource demanding but less efficient, or a mental imagery strategy, high resource demanding but more efficient. Openness was measured with the Big-5 personality questionnaire. Results: ABST reduced memory performance and disrupted more the recall of words learned with the imagery strategy. The results also showed that openness predicted recall performance associated with the imagery strategy only in the threatened group. Conclusion: These results indicated that a high level in openness may disrupt the negative effect of ABST by improving the capacity of threatened people to execute efficient, resource demanding memory strategies. This finding supports the idea that contextual factors as well as individual characteristics such as personality, need to be considered when assessing episodic memory in aging.

The Effect of Comparative Direction and Comparative Gap on Self-Deception.

Purpose: Self-deception refers to an individual holding inflated beliefs about their abilities, plays a crucial role in human behavior and decision-making. Individuals may inflate their abilities when subject to comparisons with others. This study examined the impact of social comparison on self-deception through the implementation of two behavioral experiments. Methods: In Experiment 1, we recruited a sample of 152 undergraduate students. Participants were falsely informed that they performed better (downward comparison) and worse (upward comparison) than average on a game. Subsequently, their level of self-deception was assessed by asking them to predict their performance in a future game, with more inflated predictions indicating greater self-deception. In Experiment 2, we gathered 126 undergraduate students to broaden the current study. This experiment examined the combined effects of comparison direction and comparison gap on self-deceptive behavior. Results: The findings showed that self-deception was more common in circumstances of upward comparison than in downward comparison or no comparison (Experiment 1). Furthermore, Individuals were more inclined to participate in self-deception when encountering a notable performance gap relative to others, particularly in scenarios involving upward social comparison (Experiment 2). Conclusion: The findings suggested that when confronted with threatening social comparative information, people tended to use self-deception to protect themselves. Members of the large gap group experienced strong feelings of unfairness and negative emotions, which led to self-protective behaviors and a greater likelihood of self-deception.

Lessons of the Boom: A Playbook for Crisis Centers to Prevent, Survive, and Respond to Active Assailants, Targeted Violence, and Mass Violence.

Modern crisis centers need to be prepared for mass shootings, active assailant incidents, and related forms of targeted violence. While crisis engagement has traditionally been seen as a "right of boom" or post-incident responder, crisis leaders need to prepare their teams to identify people at risk for violence, use tools like Behavioral Threat Assessment and Management to reduce risk in those persons, and prepare their teams for potential incidents in their community. Evidence suggests that acute stressors are a common proximal risk factor for severe violence implying a potential synergy for using crisis services as a tool for prevention of violence.

Multiple faces of anxiety: a frontal lobe perspective.

Marked dysregulation of the human prefrontal cortex (PFC) and anterior cingulate cortex (ACC) characterises a variety of anxiety disorders, and its amelioration is a key feature of treatment success. Overall treatment response, however, is highly variable, and about a third of patients are resistant to treatment. In this review we hypothesise that a major contributor to this variation in treatment response are the multiple faces of anxiety induced by distinct forms of frontal cortex dysregulation. Comparison of findings from humans and non-human primates reveals marked similarity in the functional organisation of threat regulation across the frontal lobes. This organisation is discussed in relation to the 'predatory imminence continuum' model of threat and the differential engagement of executive functions at the core of both emotion generation and regulation strategies.

Dreaming of being chased reflects waking-life experiences related to negative relationships with others metaphorically.

Introduction: It has long been argued that there are dream metaphors which express waking-life experiences indirectly. Most of empirical evidence concerning this topic was in a qualitative way, while few studies explored the topic in a quantitative way. Under this background, we investigated whether dreaming of the typical theme 'being chased or pursued' was a metaphorical expression for waking-life experiences related to 'negative relationships with others'. Methods: One hundred and sixty participants reported their waking-life experiences and dreams for a single day. Following this, two external judges rated whether there were any elements related to 'negative relationships with others' in both waking-life experiences and dreams. In addition, the judges assessed if there was any content related to 'being chased or pursued' in both waking-life experiences and dreams. Results: The frequency of dreaming of 'negative relationships with others' was higher than the frequency of the same topic in waking-life experiences, which in turn was higher than the frequency of typical theme dreaming of 'being chased or pursued'. In addition, 'negative relationships with others' in waking-life experiences were correlated with both dreaming of 'being chased or pursued', and 'negative relationships with others' in dreams. Conclusion: These results suggested that the typical theme 'being chased or pursued' in dreams may represent some waking-life experiences metaphorically. In addition, the results support the threat simulation theory of dreaming, which suggests that threatening events in waking life increase the possibility of threatening events in dreams.

Bed nucleus of the stria terminalis network responses to unpredictable threat in early alcohol abstinence.

BACKGROUND: Anxiety during early alcohol abstinence, likely resulting from neural changes caused by chronic alcohol use, contributes to high relapse rates. Studies in rodents show heightened activation during early abstinence in the bed nucleus of the stria terminalis (BNST)-a neural hub for anxiety-and its extended anxiety-related corticolimbic network. Despite the clinical importance of early abstinence, few studies investigate the underlying neural mechanisms. METHODS: To address this gap, we investigated brain function in early alcohol abstinence (EA = 20, 9 women) relative to controls (HC = 20, 11 women) using an unpredictable threat task shown to engage the BNST and corticolimbic brain regions involved in anxiety and alcohol use disorder (AUD). Group, anxiety, and sex were predictors used to determine whole-brain activation and BNST functional connectivity. RESULTS: We found widespread interactions of group × anxiety and group × anxiety × sex for both activation and BNST connectivity during unpredictable threat. In the EA group, higher anxiety was correlated with activation in the BNST, rostral anterior cingulate cortex (ACC), insula (men only), and dorsal ACC (men only). In the HC group, higher anxiety was negatively correlated with activation in the BNST, nucleus accumbens, thalamus, and insula (men only). For connectivity, anxiety was positively correlated in EA and negatively correlated in HC, between the BNST and the amygdala, ventromedial prefrontal cortex (PFC), and dorsomedial PFC; EA men showed stronger BNST-vmPFC connectivity than HC men. CONCLUSIONS: These novel findings provide preliminary evidence for alterations in the BNST and anxiety-related corticolimbic brain regions in early alcohol abstinence, adding to growing literature in humans supporting the BNST's role in anxiety and sex-dependent effects of chronic alcohol use.

Employee risk recognition and reporting of malicious elicitations: longitudinal improvement with new skills-based training.

Numerous security domains would benefit from improved employee risk recognition and reporting through effective security training. This study assesses the effectiveness of a new skills-based training approach to improve risk recognition and reporting of malicious elicitations. Malicious elicitations are techniques that strategically use conversation (i.e., online, in writing, in person, or over the phone) with the sole purpose of collecting sensitive, non-publicly available information about business operations, people, or technological assets without raising suspicion. To an untrained observer, a skilled elicitor can make conversations seem analogous to many professional networking situations such as those experienced over email and at conferences. A 12-month longitudinal experimental study was conducted to test training effectiveness on employees of a large corporation that focuses on serving national security needs and the public interest. Half of participants were randomly assigned to receive traditional awareness-based training (i.e., reviewing informational slides) while the other half of participants received a new skills-based training that allowed them-over the course of five weeks-to iteratively practice skills learned in the training and receive feedback on their performance in their day-to-day work environment. Following training for both experimental groups, malicious elicitations and benign professional networking test messages were sent (via email & text message) to unaware employee participants for 12 months. Findings revealed that skills-based training improved reporting of malicious elicitations and lasted for up to 12 months compared to traditional awareness-based training.

How the perfectionistic climate of a sports team predicts the athletic performance of elite athletes: a case study of the CUBAL women's basketball team.

Objective: In competitive sports, understanding how the perfectionistic climate within teams influences the performance of elite female athletes can provide valuable insights for enhancing coaching practice and athletic achievement. Based on the cognitive appraisal theory of stress, this study constructs a dual-path model using stressors and coping strategies as mediators, referred to as the Perfectionistic Climate on Athletic Performance model (PCPM). The study explores the predictive role of the perfectionistic climate within sports teams on the athletic performance of elite female basketball players. Methods: The empirical study the relationships among the variables in the model using a sample of 125 core players from the top-level women's basketball teams in the 24th CUBAL24 tournament in 2022. A Structural Equation Modeling (SEM) analysis was conducted using AMOS 20.0, primarily employing the bias-corrected Bootstrap method to test the dual-path model. Results: The findings reveal double-edged paths towards a perfectionistic climate on athletic performance. In the positive pathway, a perfectionistic climate can positively predict athletic performance through challenge-related sources of stress and positive coping strategies. In the negative pathway, a perfectionistic climate can negatively predict athletic performance through threat-related sources of stress and negative coping strategies. Conclusion: Coaches need to pay attention to athletes' cognitive evaluations of the perfectionistic climate as a source of pressure. By setting challenging goals, coaches can guide athletes to view the perfectionistic climate of the sports team as a source of challenging pressure, thus unleashing their potential. Coaches should actively guide athletes in coping with the pressure brought about by the perfectionistic climate, enhancing their ability to handle stress. This will enable athletes to better adapt to the team's perfectionistic climate and further improve individual and team athletic performance.

Assessing inoculation's effectiveness in motivating resistance to conspiracy propaganda in Finnish and United States samples.

Introduction: This study tested the motivational power of inoculation to foster resistance to conspiracy propaganda (9/11 Truth Movement), comparing inoculation effects across United States and Finnish study participants. Method: We used a 2 inoculation (treatment vs. control) × 2 national culture (American vs. Finnish) independent groups design (N = 319), while examining the effects of motivational threat and thinking modes-analytic vs. intuitive-on the inoculation process. To test the effectiveness of the inoculation strategy, we used an excerpt from a conspiracy film Loose Change as a counterattitudinal attack message. Results: Our results indicated that inoculation was effective at motivating resistance regardless of national culture. Inoculation effects emerged mostly as a direct effect on resistance and two indirect effects wherein motivational threat mediated the relationship between inoculation and resistance as well as inoculation and analytic mode of message processing. Although we found that an increase in analytic mode of processing facilitated resistance and intuitive processing increased conspiracy-theory endorsement, the indirect effects between inoculation and resistance via message processing modes were not significant. Finally, the data revealed national culture differences in analytic mode and cultural-context differences mostly pertaining to the relationships between thinking styles, media literacy, and modes of thinking. Discussion: These results offer important theoretical implications for inoculation scholarship and suggest viable practical solutions for efforts to mitigate misinformation and conspiratorial beliefs.

Applying a synergistic mindsets intervention to an esports context.

Affective responses during stressful, high-stakes situations can play an important role in shaping performance. For example, feeling shaky and nervous at a job interview can undermine performance, whereas feeling excited during that same interview can optimize performance. Thus, affect regulation-the way people influence their affective responses-might play a key role in determining high-stakes outcomes. To test this idea, we adapted a synergistic mindsets intervention (SMI) (Yeager et al. 2022 Nature 607, 512-520 (doi:10.1038/s41586-022-04907-7)) to a high-stakes esports context. Our approach was motivated by the idea that (i) mindsets both about situations and one's stress responses to situations can be shaped to help optimize stress responses, and (ii) challenge versus threat stress responses will be associated with improved outcomes. After a baseline performance task, we randomly assigned gamers (n = 300) either to SMI or a control condition in which they learned brain facts. After two weeks of daily gaming, gamers competed in a cash-prize tournament. We measured affective experiences before the matches and cardiovascular responses before and throughout the matches. Contrary to predictions, gamers did not experience negative affect (including feeling stressed), thus limiting the capacity for the intervention to regulate physiological responses and optimize performance. Compared with the control participants, synergistic mindsets participants did not show greater challenge responses or improved performance outcomes. Though our adaptation of Yeager et al.'s SMI did not optimize esports performance, our findings point to important considerations regarding the suitability of an intervention such as this to different performance contexts of varying degrees of stressfulness.

Curriculum reform and stereotype threat in medical education: Implications for student well-being.

PURPOSE: Altering the curriculum of a program can have negative repercussions for the student experience, including peer mentorships and interclass relationships. This study investigated the effect of curriculum reform on students' emotional and social well-being in a predoctoral dental program. We explored if any of these consequences could be related to stereotype threat. METHODS: We utilized a quasi-experimental design with two different treatments, New Curriculum Treatment (New-CT, n = 44) and Past Curriculum Treatment (Past-CT, n = 43). Quantitative data were collected through surveys to assess students' perceptions of curriculum changes and their impacts on anxiety, confidence, and clinical performance. Qualitative data were gathered via semi-structured interviews to explore personal experiences of stereotype threat and its implications on peer relationships and mentorship dynamics. RESULTS: The findings suggest significant effects of curriculum changes on interpersonal relationships. Past-CT viewed New-CT as overconfident, while New-CT felt heightened performance pressure. Thematic and interview analyses revealed deep-rooted tensions, with New-CT feeling mistrusted and Past-CT resenting New-CT's perceived accelerated competence. Stereotype threat was identified as a key factor worsening these inter-group tensions and affecting clinical performance and relationships. CONCLUSIONS: Curriculum changes in dental education can significantly affect students' well-being, with stereotype threat playing a critical role in these dynamics. When making changes to the structure, sequencing, or content of a program, administrators need to be aware of the potential ramifications these changes could have on students' relationships with their peers.

Do wars abroad affect attitudes at home?

Can foreign conflicts affect attitudes in nonbelligerent countries? A large literature studies the effects of conflicts and wars on countries that are directly involved, without considering the potential consequences for other nonbelligerent countries that might nevertheless be threatened. To address this question, we examine how the Russian invasion of Ukraine affected 12 economic and political attitudes using survey data covering eight European countries. We use a natural experiment whereby the timing of the invasion overlapped with the fieldwork of a cross-national individual-level survey in these eight countries. We find that the war increased support for democracy, redistribution, support for Europe, and immigration, while it reduced authoritarian attitudes. Our findings highlight the impact of foreign conflicts on a wide range of attitudes in countries that are externally threatened, but neither directly involved militarily, nor necessarily very close to the conflict.

Collective order and group structure of shoaling fish subject to differing risk-level treatments with a sympatric predator.

It is imperative for individuals to exhibit flexible behaviour according to ecological context, such as available resources or predation threat. Manipulative studies on responses to threat often focus on behaviour in the presence of a single indicator for the potential of predation, whereas in the wild perception of threat will probably be more nuanced. Here, we examine the collective behaviour of eastern mosquitofish (Gambusia holbrooki) subject to five differing threat scenarios relating to the presence and hunger state of a jade perch (Scortum barcoo). Across threat scenarios, groups exhibit unique behavioural profiles that differ in the durations that particular collective states are maintained, the probability of transitions between states, the size and duration of persistence of spatially defined subgroups, and the patterns of collective order of these subgroups. Under the greatest level of threat, subgroups of consistent membership persist for longer durations. Group-level behaviours, and their differences, are interconnected with differences in estimates of the underlying rules of interaction thought to govern collective motion. The responses of the group are shown to be specific to the details of a potential threat, rather than a binary response to the presence or absence of some form of threat.

Auditory guidance of eye movements toward threat-related images in the absence of visual awareness.

The human brain is sensitive to threat-related information even when we are not aware of this information. For example, fearful faces attract gaze in the absence of visual awareness. Moreover, information in different sensory modalities interacts in the absence of awareness, for example, the detection of suppressed visual stimuli is facilitated by simultaneously presented congruent sounds or tactile stimuli. Here, we combined these two lines of research and investigated whether threat-related sounds could facilitate visual processing of threat-related images suppressed from awareness such that they attract eye gaze. We suppressed threat-related images of cars and neutral images of human hands from visual awareness using continuous flash suppression and tracked observers' eye movements while presenting congruent or incongruent sounds (finger snapping and car engine sounds). Indeed, threat-related car sounds guided the eyes toward suppressed car images, participants looked longer at the hidden car images than at any other part of the display. In contrast, neither congruent nor incongruent sounds had a significant effect on eye responses to suppressed finger images. Overall, our results suggest that only in a danger-related context semantically congruent sounds modulate eye movements to images suppressed from awareness, highlighting the prioritisation of eye responses to threat-related stimuli in the absence of visual awareness.

Age-based stereotype threat effects on dynamic balance in healthy older adults.

Introduction: Stereotype threat can lead older adults to perceive their experiences in a biased manner, giving rise to interfering thoughts and negative emotions that generate stress and anxiety. Negative beliefs about aging may serve as an additional factor that increases the need for attentional demand, potentially resulting in a performance level below their actual capabilities. In the present study, we asked whether negative aging stereotypes influence a dynamic balance task and explored the means to counteract them in healthy elderly participants. Methods: The performance of balance was compared in two groups of participants aged 65 to 75 years (n = 22) under stereotype threat or reduced-threat situation. Balance abilities were tested under dynamic conditions, requiring participants to maintain balance on a moving platform and using a gradient of difficulty (with eyes open or closed, without or with foam). Postural performance was evaluated by means of posturographic evaluation of the center of pressure displacement and motion analysis. Additionally, we investigated the effects of stereotype threat on a preferred walking speed task and on the Timed Up and Go (TUG) test. Results: Participants under stereotype threat showed poorer balance, particularly in challenging conditions (eyes closed, on foam), with less effective body segments stabilization. Their postural stabilization on foam was worse compared to a solid surface. Conversely, those in the reduced threat condition maintained better body segment stabilization across all conditions, indicating consistent postural control regardless of the presence of foam. Stereotype threat did not affect preferred walking speed or the time to complete the "Time Up and Go" test. Discussion-conclusion: This study provides the first description of age-based stereotype threat effects on a dynamic balance task and how to counteract them in healthy older adults. We suggest that the decrease in postural performance observed in participants exposed to stereotype threat can be attributed to a split in attentional focus between negative intrusive thoughts and the attention needed for maintaining balance. These findings open new perspectives on how to overcome negative expectations when evaluating and training physical abilities, thereby contributing to fall prevention among older adults.
