RESUMO

Globalizing economies and long-distance trade rely on individuals from different cultural groups to negotiate agreement on what to give and take. In such settings, individuals often lack insight into what interaction partners deem fair and appropriate, potentially seeding misunderstandings, frustration, and conflict. Here, we examine how individuals decipher distinct rules of engagement and adapt their behavior to reach agreements with partners from other cultural groups. Modeling individuals as Bayesian learners with inequality aversion reveals that individuals, in repeated ultimatum bargaining with responders sampled from different groups, can be more generous than needed. While this allows them to reach agreements, it also gives rise to biased beliefs about what is required to reach agreement with members from distinct groups. Preregistered behavioral (N = 420) and neuroimaging experiments (N = 49) support model predictions: Seeking equitable agreements can lead to overly generous behavior toward partners from different groups alongside incorrect beliefs about prevailing norms of what is appropriate in groups and cultures other than one's own.

RESUMO

Although experiments show that exposure to factual information can increase factual accuracy, the public remains stubbornly misinformed about many issues. Why do misperceptions persist even when factual interventions generally succeed at increasing the accuracy of people's beliefs? We seek to answer this question by testing the role of information exposure and decay effects in a four-wave panel experiment (n = 2,898 at wave 4) in which we randomize the media content that people in the United States see about climate change. Our results indicate that science coverage of climate change increases belief accuracy and support for government action immediately after exposure, including among Republicans and people who reject anthropogenic climate change. However, both effects decay over time and can be attenuated by exposure to skeptical opinion content (but not issue coverage featuring partisan conflict). These findings demonstrate that the increases in belief accuracy generated by science coverage are short lived and can be neutralized by skeptical opinion content.

RESUMO

Beliefs can be highly resilient in the sense that they are not easily abandoned in the face of counterevidence. This has the advantage of guiding consistent behavior and judgments but may also have destructive consequences for individuals, nature, and society. For instance, pathological beliefs can sustain psychiatric disorders, the belief that rhinoceros horn is an aphrodisiac may drive a species extinct, beliefs about gender or race may fuel discrimination, and belief in conspiracy theories can undermine democracy. Here, we present a unifying framework of how self-amplifying feedbacks shape the inertia of beliefs on levels ranging from neuronal networks to social systems. Sustained exposure to counterevidence can destabilize rigid beliefs but requires organized rational override as in cognitive behavioral therapy for pathological beliefs or institutional control of discrimination to reduce racial biases. Black-and-white thinking is a major risk factor for the formation of resilient beliefs associated with psychiatric disorders as well as prejudices and conspiracy thinking. Such dichotomous thinking is characteristic of a lack of cognitive resources, which may be exacerbated by stress. This could help explain why conspiracy thinking and psychiatric disorders tend to peak during crises. A corollary is that addressing social factors such as poverty, social cleavage, and lack of education may be the most effective way to prevent the emergence of rigid beliefs, and thus of problems ranging from psychiatric disorders to prejudices, conspiracy theories, and posttruth politics.

RESUMO

Bayesian models of perception posit that percepts result from the optimal integration of new sensory information and prior expectations. In turn, prominent models of perceptual disturbances in psychosis frame hallucination-like phenomena as percepts excessively biased toward perceptual prior expectations. Despite mounting support for this notion, whether this hallucination-related prior bias results secondarily from imprecise sensory representations at early processing stages or directly from alterations in perceptual priors-both suggested candidates potentially consistent with Bayesian models-remains to be tested. Using modified interval timing paradigms designed to arbitrate between these alternative hypotheses, we show in human participants (16 females and 24 males) from a nonclinical population that hallucination proneness correlates with a circumscribed form of prior bias that reflects selective differences in weighting of contextual prior variance, a prior bias that is unrelated to the effect of sensory noise and to a separate index of sensory resolution. Our results thus suggest distinct mechanisms underlying prior biases in perceptual inference and favor the notion that hallucination proneness could reflect direct alterations in the representation or use of perceptual priors independent of sensory noise.SIGNIFICANCE STATEMENT Current theories of psychosis posit that hallucination proneness results from excessive influence of prior expectations on perception. It is not clear whether this prior bias represents a primary top-down process related to the representation or use of prior beliefs or instead a secondary bottom-up process stemming from imprecise sensory representations at early processing stages. To address this question, we examined interval timing behaviors captured by Bayesian perceptual-inference models. Our data support the notion that excessive influence of prior expectations associated with hallucination propensity is not directly secondary to sensory imprecision and is instead more consistent with a primary top-down process. These results help refine computational theories of psychosis and may contribute to the development of improved intervention targets.

RESUMO

Despite increased risk of severe acute respiratory syndrome coronavirus 2 infections and higher rates of COVID-19-related complications, racialized and Indigenous communities in Canada have lower immunization uptake compared to White individuals. However, there is woeful lack of data on predictors of COVID-19 vaccine mistrust (VM) that accounts for diverse social and cultural contexts within specific racialized and Indigenous communities. Therefore, we sought to characterize COVID-19 VM among Arab, Asian, Black, and Indigenous communities in Canada. An online survey was administered to a nationally representative, ethnically diverse panel of participants in October 2023. Arabic, Asian, Indigenous, and Black respondents were enriched in the sampling panel. Data were collected on demographics, COVID-19 VM, experience of racial discrimination, health literacy, and conspiracy beliefs. We used descriptive and regression analyses to determine the extent and predictors of COVID-19 VM among racialized and Indigenous individuals. All racialized respondents had higher VM score compared to White participants. Among 4220 respondents, we observed highest VM among Black individuals (12.18; ±4.24), followed by Arabic (12.12; ±4.60), Indigenous (11.84; ±5.18), Asian (10.61; ±4.28), and White (9.58; ±5.00) participants. In the hierarchical linear regression analyses, Black participants, women, everyday racial discrimination, and major experience of discrimination were positively associated with COVID-19 VM. Effects of racial discrimination were mediated by addition of conspiracy beliefs to the model. Racialized and Indigenous communities experience varying levels of COVID-19 VM and carry specific predictors and mediators to development of VM. This underscores the intricate interaction between race, gender, discrimination, and VM that need to be considered in future vaccination campaigns.

RESUMO

OBJECTIVE: Regular screening can lead to early diagnosis of breast cancer. Australia is one of the countries with a high rate of participation in breast cancer screening, while in Iran, most patients are diagnosed in advanced stages. This qualitative study used a thematic analysis method to examine the attitudes and beliefs of Iranian and Australian women toward breast cancer and breast cancer screening. METHOD: In-depth interviews were conducted with eight Iranian and seven Australian women. Data were collected through semi-structured interviews and analyzed using thematic analysis with an inferential approach. RESULTS: According to the results, four main themes were extracted for the perceptions of breast cancer, including "the meaning of breast cancer", "causes of breast cancer", "prevention of breast cancer" and "effects of significant people in life". Considering the perceptions of breast cancer screening, three themes were identified, including "beliefs about breast cancer screening," "sources of information about breast cancer screening," and "barriers to breast cancer screening." CONCLUSION: Cultural and social factors influence women's perceptions of breast cancer and screening. Therefore, investigating the cultural meaning of breast cancer and breast cancer screening for women can be useful for screening and prevention purposes.

RESUMO

BACKGROUND: Personal characteristics may be associated with believing misinformation and not believing in best practices to protect oneself from COVID-19. OBJECTIVE: To examine the associations of a person's age, race/ethnicity, education, residence, health literacy, medical mistrust level, and sources of health-related information with their COVID-19 health and conspiracy myth beliefs. DESIGN: We surveyed adults with hypertension in Maryland and Pennsylvania between August 2020 and March 2021. Incorrect responses were summed for eight health (mean = 0.68; range 0-5) and two conspiracy (mean = 0.92; range 0-2) COVID-19 questions. Higher scores indicated more incorrect responses. Statistical analyses included two-sample t-tests, Spearman's correlation, and log binomial regression. PARTICIPANTS: In total, 561 primary care patients (mean age = 62.3 years, 60.2% female, 46.0% Black, 10.2% Hispanic, 28.2% with a Bachelor's degree or higher, 42.8% with annual household income less than $60,000) with a diagnosis of hypertension and at least one of five commonly associated conditions. MAIN MEASURES: Sociodemographic characteristics, health literacy, medical mistrust level, source of health-related information, and COVID-19 conspiracy and health myth beliefs. KEY RESULTS: In multivariable analyses, participants who did not get information from medical professional sources (prevalence ratio (PR) = 1.28; 95% CI = 1.06-1.55), had less than a bachelor's degree (PR = 1.49; 95% CI = 1.12-1.99), were less confident filling out medical forms (PR = 1.24; 95% CI = 1.02-1.50), and had higher medical mistrust (PR = 1.34; 95% CI = 1.05-1.69) were more likely to believe any health myths. Participants who had less than a bachelor's degree (PR = 1.22; 95% CI = 1.02-1.45), were less confident filling out medical forms (PR = 1.21; 95% CI = 1.09-1.34), and had higher medical mistrust (PR = 1.72; 95% CI = 1.43-2.06) were more likely to believe any conspiracy myths. CONCLUSIONS: Lower educational attainment and health literacy, greater medical mistrust, and certain sources of health information are associated with misinformed COVID-19 beliefs. Programs addressing misinformation should focus on groups affected by these social determinants of health by encouraging reliance on scientific sources.

RESUMO

BACKGROUND: Cervical cancer remains a significant but preventable threat to women's health throughout much of the developing world, including Uganda. Cervical cancer screening and timely treatment of pre-cancerous lesions is a cost-effective means of mitigating cervical cancer morbidity and mortality. However, only 5% of women in Uganda have ever been screened. Barriers to screening, such as social stigma and access to safe conditions, have been previously identified, but insights into the role of male spouses in encouraging or discouraging screening have been limited. To our knowledge, no studies have compared barriers and facilitators among women who had or had not yet been screened and male partners of screened and unscreened women. METHODS: To resolve this gap, we conducted 7 focus groups- 3 among women who had been screened, 3 among those who had not been screened, and 1 among men whose female partners had or had not been screened. We performed qualitative thematic analysis on the focus group data. RESULTS: We identified several important factors impacting screening and the decision to screen among women, ranging from stigma, availability of screening, false beliefs around the procedure and side effects, and the role of spousal support in screening promotion. Male spousal perspectives for screening ranged from full support to hesitancy around male-performed exams and possible prolonged periods without intercourse. CONCLUSION: This exploratory work demonstrates the importance of dialogue both among women and their male partners in enhancing screening uptake. Efforts to address screening uptake are necessary given that it is an important means of mitigating the burden of cervical cancer. Interventions along these lines need to take these barriers and facilitators into account in order to drive up demand for screening.

RESUMO

BACKGROUND: We compared dissociative seizure specific cognitive behavior therapy (DS-CBT) plus standardized medical care (SMC) to SMC alone in a randomized controlled trial. DS-CBT resulted in better outcomes on several secondary trial outcome measures at the 12-month follow-up point. The purpose of this paper is to evaluate putative treatment mechanisms. METHODS: We carried out a secondary mediation analysis of the CODES trial. 368 participants were recruited from the National Health Service in secondary / tertiary care in England, Scotland, and Wales. Sixteen mediation hypotheses corresponding to combinations of important trial outcomes and putative mediators were assessed. Twelve-month trial outcomes considered were final-month seizure frequency, Work and Social Adjustment Scale (WSAS), and the SF-12v2, a quality-of-life measure providing physical (PCS) and mental component summary (MCS) scores. Mediators chosen for analysis at six months (broadly corresponding to completion of DS-CBT) included: (a) beliefs about emotions, (b) a measure of avoidance behavior, (c) anxiety and (d) depression. RESULTS: All putative mediator variables except beliefs about emotions were found to be improved by DS-CBT. We found evidence for DS-CBT effect mediation for the outcome variables dissociative seizures (DS), WSAS and SF-12v2 MCS scores by improvements in target variables avoidance behavior, anxiety, and depression. The only variable to mediate the DS-CBT effect on the SF-12v2 PCS score was avoidance behavior. CONCLUSIONS: Our findings largely confirmed the logic model underlying the development of CBT for patients with DS. Interventions could be additionally developed to specifically address beliefs about emotions to assess whether it improves outcomes.

RESUMO

BACKGROUND: Given the unprecedented aging of the population and the increased focus on overall well-being in older age, investigating the determining factors of sexual well-being in older adults becomes essential as it offers insights into promoting healthy aging and overall quality of life. AIM: By applying the biopsychosocial model of sexuality in older age, we aimed to identify the role of biomedical and psychosocial factors in predicting sexual well-being in partnered older adults (≥55 years old). METHODS: A total of 111 participants (mean [SD], 63.2 [5.96]) completed a self-report questionnaire assessing biopsychosocial dimensions. Bivariate correlational analyses and hierarchical multiple regression were conducted to investigate factors associated with sexual well-being. Health-related factors were entered into the first regression model. The second model included factors pertaining to relationship dimensions. Sexual beliefs were introduced in the third regression model. OUTCOMES: Self-rated health, psychological distress, subjective cognitive decline, sexual beliefs, duration of the relationship, relationship satisfaction, and sexual well-being were assessed. RESULTS: Findings from the hierarchical regression revealed that duration of relationship [t(104) = -3.07, P < .01], relationship satisfaction [t(104) = 8.49, P < .001], and age-related sexual beliefs [t(104) = -2.75, P < .01] were significant predictors of sexual well-being of partnered older adults [F(6, 104) = 22.77, P < .001, R2 = .57], after controlling for health-related factors. These findings suggest that relationship factors and sexual beliefs play a significant role in predicting sexual well-being of older adults, above and beyond health-related dimensions. CLINICAL IMPLICATIONS: Interventional approaches aimed at promoting sexual well-being in older age might benefit from incorporating exercises that demystify age-related sexual beliefs, by normalizing changes that occur with aging and fostering positive attitudes toward sexual expression in older age; particularly for older adults in long-term relationships, relationship satisfaction must also be considered as an important intervention target. STRENGTHS AND LIMITATIONS: Further investigation using longitudinal designs is required to examine the causal links between these factors and sexual well-being in older age. CONCLUSION: Findings from this study underscore the role of relationship dimensions and age-related sexual beliefs for the sexual well-being of partnered older adults.

RESUMO

Key mechanisms of change in cognitive behavioural therapy for insomnia in the general population encompass changing sleep-related beliefs and behaviours. In a population with acquired brain injury, cognitive behavioural therapy for insomnia is effective as well, but little is known about the mechanisms of change. The aim of this study was to evaluate how changing sleep-related beliefs and behaviours were associated with improvement in insomnia following blended cognitive behavioural therapy for insomnia in a population with acquired brain injury. A secondary analysis was performed on data of a randomized-controlled trial, including 24 participants that received blended cognitive behavioural therapy for insomnia, and 24 participants that received treatment as usual. Results showed that following blended cognitive behavioural therapy for insomnia, significantly more participants improved on dysfunctional beliefs and sleep-related behaviours and this was associated to improvement in insomnia severity. For sleep-related behaviours, the association between improvement on behaviour and improvement on insomnia was significantly moderated by blended cognitive behavioural therapy for insomnia. However, the relation between dysfunctional beliefs and insomnia was not moderated by type of treatment. Similar results were found for acquired brain injury-adapted versions of the questionnaires in which up to half of the items were excluded as they could be regarded as not dysfunctional for people with acquired brain injury. These results show that improvement on insomnia severity is related to improvement in dysfunctional beliefs and behaviours, and cognitive behavioural therapy for insomnia efficacy may be moderated by the improvement in behaviours in particular. A focus on these behaviours can enhance treatment efficacy, but caution is needed regarding the behaviours that may reflect adequate coping with the consequences of the acquired brain injury.

RESUMO

BACKGROUND: To date, research investigating psychosocial correlates of COVID-19 vaccination has been cross-sectional, parochial, and/or reliant upon non-stratified international samples, resulting in difficulty in clarifying the contributions of various vaccination-related influences. PURPOSE: The present study tested a novel integration of prospective and concurrent associations of demographic and dispositional tendencies, intervening illness and preventive beliefs, vaccine intention, illness experiences, and concurrent contextual vaccine-related influences with subsequent COVID-19 vaccination. METHODS: The preregistered study used a stratified online U.S. sample (N = 500), with assessments aligned to (a) "15 days to slow the spread" in March 2020, (b) vaccine authorization and major case/mortality surge during December 2020 and January 2021, and (c) the period following full vaccine approval in August 2021 during the third major/case mortality surge during September and October 2021. RESULTS: Path modeling showed the absence of children in the household and greater education were prospective predictors of vaccination. Trait openness and less conservative political beliefs showed indirect prospective associations with vaccination via stronger intermediating vaccine intention. Contextual vaccine-related influences of vaccine-related information sources, employer mandates, and flu vaccine history also showed direct associations with vaccination. In contrast to expectations, lower conscientiousness showed a direct prospective association with vaccination. CONCLUSIONS: Controlling for interrelations among study variables, the results of the integrative psychosocial model clarified the unique contributions and pathways from antecedent characteristics to vaccination while accounting for vaccine-related contextual influences, providing further direction for refining the timing and content of public health messaging for vaccination.


The present study used 3 assessments across 18 months to investigate psychosocial and behavioral predictors of COVID-19 vaccination in a stratified U.S. sample. Consistent with preregistered hypotheses, the absence of children in the household and greater education assessed in March 2020, predicted vaccination by the fall of 2021. Greater vaccination intention during the Delta surge from December 2020 to January 2021 (prior to widespread vaccine availability), predicted vaccination by the fall of 2021. In addition, greater trait openness (curious, reflective) and less conservative political beliefs assessed during March 2020, predicted vaccination through stronger vaccination intention. Employer vaccine mandates, a stronger history of flu vaccination, and the use of more reliable health information sources for COVID-19 vaccines also predicted greater vaccination. Contrary to expectations, greater conscientiousness (careful, thorough) assessed during March 2020, predicted less vaccination by the fall of 2021. Notably, the results suggest that for some parents, general vaccine concerns, however, misinformed, may have extended to the consideration of COVID-19 vaccines for themselves. Moreover, for more careful and thorough individuals, novel vaccine hesitancy may be an expression of perceived harm avoidance that is specific to the vaccine, rather than to perceived risks of infection or illness.

RESUMO

BACKGROUND: Cigarette pack inserts with messages on cessation benefits and advice are a promising labeling policy that may help promote smoking cessation. PURPOSE: To assess insert effects, with and without accompanying pictorial health warning labels(HWLs), on hypothesized psychosocial and behavioral outcomes. METHODS: We conducted a 2 × 2 between-subject randomized trial (inserts with efficacy messages vs. no inserts; large pictorial HWLs vs. small text HWLs), with 367 adults who smoked at least 10 cigarettes a day. Participants received a 14-day supply of their preferred cigarettes with packs modified to reflect their experimental condition. Over 2 weeks, we surveyed participants approximately 4-5 times a day during their smoking sessions, querying feelings about smoking, level of worry about harms from smoking, self-efficacy to cut down on cigarettes, self-efficacy to quit, hopefulness about quitting, and motivation to quit. Each evening, participants reported their perceived susceptibility to smoking harms and, for the last 24 hr, their frequency of thinking about smoking harms and cessation benefits, conversations about smoking cessation or harms, and foregoing or stubbing out cigarettes before they finished smoking. Mixed-effects ordinal and logistic models were estimated to evaluate differences between groups. RESULTS: Participants whose packs included inserts were more likely than those whose packs did not include inserts to report foregoing or stubbing out of cigarettes (OR = 2.39, 95% CI = 1.36, 4.20). Otherwise, no statistically significant associations were found between labeling conditions and outcomes. CONCLUSIONS: This study provides some evidence, albeit limited, that pack inserts with efficacy messages can promote behaviors that predict smoking cessation attempts.


Cigarette pack inserts (small leaflets inside packs) with messages about quitting benefits and tips to quit may promote smoking cessation. We randomly assigned 367 adult smokers to one of four groups: control group with small health warning labels (HWLs) on the side of packs; inserts with cessation messages and small HWLs; large picture HWLs showing health effects from smoking; inserts and large picture HWLs. Participants received a 14-day supply of their preferred cigarettes in packs that reflected their assigned group. Over 2 weeks, we surveyed participants 4­5 times a day during times when they smoked, asking their feelings about smoking and smoking-related harms, confidence to reduce cigarettes and quit, hopefulness about quitting, and motivation to quit. Each evening, participants reported on the prior 24 hr: how often they thought about smoking harms and cessation benefits; conversations about smoking cessation or harms; and foregoing or stubbing out cigarettes before they finished smoking. People whose packs had inserts (with or without picture HWLs) were more likely than those whose packs did not include inserts (control group or picture HWLs only) to report foregoing or stubbing out of cigarettes. This study provides some evidence that inserts with cessation messages may promote smoking cessation.

RESUMO

INTRODUCTION: Widespread misperceptions about nicotine may have unintended effects on public health. We examined associations between existing messages about nicotine or tobacco and beliefs about nicotine and reduced nicotine cigarettes (RNC). METHODS: 2962 U.S. 18-45-year-olds were randomized in a May 2022 web-based survey to view one of 26 text-based messages about tobacco or nicotine from three sources: ongoing research (n = 8), messages authorized by FDA for VLN cigarettes (n = 6), and FDA's "From Plant to Product to Puff" campaign (n = 12); six messages from FDA's campaign did not reference nicotine and were treated as the reference source. Analyses examined associations between messages, grouped by source and individually, with beliefs about nicotine and RNC addictiveness and harms. RESULTS: Relative to FDA messages that did not reference nicotine, all message sources were associated with greater odds of a correct belief about nicotine (Odds Ratios [ORs] = 1.40-1.87, p's < 0.01); VLN messages were associated with greater correct beliefs about RNC addictiveness (b = 0.23, p < .05). No campaign produced greater correct beliefs about RNC harms. At the individual level, only five messages were associated with a correct belief about nicotine (ORs = 2.12-2.56, p-values < .01), and one with correct beliefs about RNC harms (b = 1.09, p < .05), vs. the reference message. CONCLUSIONS: Few existing messages improved understanding of the risks of nicotine separately from the risks of combustible products. Communication research is needed to promote greater public understanding of nicotine while minimizing unintended effects on nicotine and tobacco use.

RESUMO

This cross-sectional analysis aimed to describe beliefs about antiretroviral therapy (ART) in young people living with perinatal HIV (PHIV) in England, and the association between these beliefs and adherence to ART. The Beliefs About Medicine Questionnaire (Highly Active Antiretroviral Therapy version), was used to measure participants' beliefs in the necessity of ("Necessity score") and concerns regarding ("Concerns score") ART. Participants were classified as having high/low total scores using midpoints of the score scales. Associations between beliefs and being Last Month Adherent (LMA; self-reported not missing more than 2 consecutive ART doses in the month prior to the interview) were analysed using logistic regression, adjusting for sociodemographic, clinical, and psychosocial variables. Of 247 PHIV (median age = 18.6 years), 158 (64%) were LMA. 224 (91%) had a high Necessity score and 54 (22%) a high Concerns score. There was no association between high Necessity score and LMA in multivariable analysis (adjusted odds ratio (aOR) = 1.34, 95% confidence interval (CI) = 0.34-5.28, p = 0.679); however, high Concerns score was independently associated with a reduced odds of being LMA (aOR = 0.19, CI = 0.07-0.47, p < 0.001). Interventions to address the concerns young people living with PHIV have about ART should be explored as a strategy to improve their adherence.

RESUMO

Zoos and aquariums are well placed to connect visitors with the issues facing biodiversity globally and many deliver interventions that seek to influence visitors' beliefs and behaviors with respect to conservation. However, despite primary studies evaluating the effect of such interventions, the overall effect of engaging with zoos and the factors that influence this effect remain unclear. We conducted a systematic review to investigate the effect of zoo-led interventions on knowledge, beliefs (attitudes, intentions, self-efficacy, and social norms), and behavior among zoo visitors. These outcomes were identified using the Theory of Planned Behavior as a theoretical lens. We identified and described the nature of zoo-led interventions in 56 studies and used the behavior change technique (BCT) taxonomy to identify 6 specific BCTs used in interventions to date. Multilevel meta-analyses revealed a small to medium positive effect of engaging with zoo-led interventions on outcomes (d+  = 0.40, 95% confidence interval = 0.28-0.51). Specifically, visitors were more knowledgeable about conservation issues, held more favorable attitudes toward conservation, and reported being more likely to act for the benefit of biodiversity. No evidence of publication bias was present. Effect sizes were, however, heterogeneous and subgroup analyses revealed that the nature of the intervention or type of outcome did not explain this variance. Larger effects were, however, found in studies conducted at a single institution relative to research at multiple institutions and studies that used within-participant designs relative to between-participant designs. Taken together, these findings demonstrate how behavior change frameworks can be used to describe zoo-led interventions and supports the assertion that zoos and aquariums can promote changes in beliefs and behaviors that may help protect biodiversity.


Metaanálisis del efecto de la visita a acuarios y zoológicos sobre el conocimiento, creencias y comportamientos de conservación de los visitantes © 2024 by John Wiley & Sons, Inc. Resumen Los zoológicos y los acuarios están bien posicionados para conectar a los visitantes con temas mundiales de biodiversidad y varios cuentan con intervenciones que buscan influir las creencias y el comportamiento de los visitantes con respecto a la conservación. Sin embargo, con todo y los estudios primarios que evalúan el efecto de dichas intervenciones, aún no está claro el efecto general de participar en los zoológicos y los factores que influyen sobre este efecto. Realizamos una revisión sistemática para investigar el efecto de las intervenciones en los zoológicos sobre el conocimiento, creencias (actitud, intención, autosuficiencia y normas sociales) y comportamiento de sus visitantes. Usamos la teoría del comportamiento planeado como lente teórico para identificar los resultados. Identificamos y describimos la naturaleza de las intervenciones en los zoológicos en 56 estudios y usamos la taxonomía de las técnicas de modificación de conducta (TMC) para identificar seis TMC específicas que se usan hoy en día en dichas intervenciones. Los metaanálisis multinivel revelaron un efecto positivo de pequeño a mediano sobre los resultados causado por la participación en las intervenciones de los zoológicos (d+ = 0.40, 95% CI = 0.28 - 0.51). En específico, los visitantes fueron más conocedores sobre los temas de conservación, tuvieron actitudes más favorables hacia la conservación y reportaron tener mayor probabilidad de actuar en beneficio de la biodiversidad. No hubo evidencias de sesgos en las publicaciones. Sin embargo, el tamaño de los efectos fue heterogéneo y el análisis de los subgrupos reveló que la naturaleza de la intervención o el tipo de resultados no explicaban esta varianza. A pesar de esto, encontramos efectos más grandes en los estudios realizados en una sola institución en relación con la investigación realizada en varias instituciones y los estudios que usaron diseños intraparticipantes en relación a los que usaron diseños interparticipantes. Nuestra revisión demuestra cómo los marcos de modificación conductual pueden usarse para describir las intervenciones en los zoológicos y acuarios y respalda la aseveración de que estas instituciones pueden promover cambios en las creencias y el comportamiento que pueden ayudar a proteger la biodiversidad.

RESUMO

The influence of the epistemological beliefs of parents on the development of comprehensive scientific reasoning abilities was investigated in a five-wave longitudinal study from kindergarten to elementary school. The 161 German 5-10-year-olds (89 girls, 72 boys) were assessed yearly on their scientific reasoning abilities using comprehensive measures for experimentation and data-interpretation skills, as well as understanding of the nature of science. The children were also tested on their language abilities and intelligence. Their parents completed a sociodemographics questionnaire and answered ten questions about their epistemological beliefs regarding (1) the interpretive nature of science, (2) the tentative nature of knowledge, and (3) the role of scientific framework theories. The personal epistemology of the parents significantly predicted the scientific reasoning development of their children regardless of the parents' education level and the children's general cognitive abilities. However, the effect of the epistemology of parents on their children's scientific reasoning was limited to the intercepts, suggesting that the epistemic understanding of parents affects how scientific reasoning develops in their children, but not the development speed. Although parental epistemology exerts substantial effects on scientific reasoning of their children, it did not affect their reading ability, suggesting an involvement of science-specific mechanisms rather than generalized family-based influences. These findings highlight the importance of family as a variable in the development of scientific reasoning, which is an area lacking in research, and it suggests that early interventions targeted at the epistemic understanding of caregivers can provide useful ways for promoting the reasoning of children. RESEARCH HIGHLIGHTS: A five-year longitudinal study shows significant development of scientific reasoning from kindergarten to elementary school. Caregivers' personal epistemology predicted scientific reasoning development-independent of children's general cognitive abilities and caregivers' level of education. The effect was most-pronounced for caregivers' understanding that social framework theories determine which aspects of science are accepted and how they are conducted. Caregivers' personal epistemology did not predict children's reading abilities, suggesting that the effect of the caregivers' epistemology on children's scientific reasoning is domain-specific.

RESUMO

Success in science, technology, engineering, and mathematics (STEM) fields is often believed to require intellectual talent ("brilliance"). Given that many cultures associate men more than women with brilliance, this belief poses an obstacle to women's STEM pursuits. Here, we investigated the developmental roots of this phenomenon, focusing specifically on young children's beliefs about math (N = 174 U.S. students in Grades 1-4; 93 girls, 81 boys; 52% White, 17% Asian, 13% Hispanic/Latinx). We found that field-specific ability beliefs (FABs) that associate success in math (vs. reading/writing) with brilliance are already present in early elementary school. We also found that brilliance-oriented FABs about math are negatively associated with elementary school students' (and particularly girls') math motivation-specifically, their math self-efficacy and interest. The early emergence of brilliance-oriented FABs about math and the negative relation between FABs and math motivation underscore the need to understand the sources and long-term effects of these beliefs. RESEARCH HIGHLIGHTS: Field-specific ability beliefs (FABs) are beliefs about the extent to which intellectual talent (or "brilliance") is required for success in a particular field or context. Among adults, brilliance-oriented FABs are an obstacle to diversity in science and technology, but the childhood antecedents of these beliefs are not well understood. The present study (N = 174) found that FABs that associate success in math (vs. reading/writing) with brilliance were already present in Grades 1-4. Brilliance-oriented FABs about math were negatively associated with elementary school students' (and particularly girls') math motivation-specifically, their math self-efficacy and interest.

RESUMO

BACKGROUND: Persons with albinism face challenges to their wellbeing, safety, and security, ranging from vision impairment and skin cancer to stigma and discrimination. In some regions, they also face human rights atrocities including mutilation and murder. Research on human rights and albinism is a relatively new field that has gained momentum since the United Nations appointment of an Independent Expert on the enjoyment of human rights by persons with albinism. In this paper, we present the results of a mixed methods study undertaken to identify priorities for research, advocacy, and policy on albinism and human rights. METHODS: The first component was a synthesis of peer-reviewed and grey literatures at the nexus of albinism, spiritual/cultural beliefs and practices, and human rights. We then conducted a priority-setting survey, informed by Delphi methods, on extant knowledge-practice gaps and research, advocacy, and policy priorities. Inclusion criteria included demonstrated expertise in the field (e.g., peer-reviewed publications, funded research), membership on national or international associations, or advocacy (civil society organizations) of more than 2 years in albinism and human rights. Thereafter, we gathered leading researchers, policy-makers, and civil society stakeholders for a Roundtable to gain consensus on these priorities. RESULTS: Access to skin and vision care, and education were not deemed high priority for research, likely because the evidence supporting the need for these is well established. However, they were priorities for advocacy and policy: what is needed is mobilization of this evidence through advocacy and implementation of such services (policy). Other social determinants of health (rurality, poverty, and gender equality) are present as subtext in the findings, more so than priorities for research, advocacy, or policy, despite their preponderance in the lives of persons with albinism. Research was prioritized on stigma and discrimination; advocacy; and witchcraft, but with some differentiation between Global North and Global South priorities. Priorities for research, advocacy, and policy vary in keeping with the explanatory frameworks at play, including how harmful practices and witchcraft are viewed. CONCLUSIONS: The lived experience of albinism is profoundly shaped by the social determinants of health (SDOH). Threats to the security and well-being of persons with albinism should be viewed through a human rights lens that encompasses the explanatory frameworks at play.

RESUMO

OBJECTIVE: In this cross-sectional study, the authors aimed to examine relationships between illness perception, measured as symptom attribution, and neurobehavioral and neurocognitive outcomes among veterans with a history of traumatic brain injury (TBI). METHODS: This study included 55 treatment-seeking veterans (N=43 with adequate performance validity testing) with a remote history of TBI (80% with mild TBI). Veterans completed a clinical interview, self-report questionnaires, and a neuropsychological assessment. A modified version of the Neurobehavioral Symptom Inventory (NSI) was administered to assess neurobehavioral symptom endorsement and symptom attribution. Composite scores were calculated from standardized cognitive tests to assess specific aspects of objective cognitive functioning, including memory, executive functioning, attention and working memory, and processing speed. RESULTS: The symptoms most frequently attributed to TBI included forgetfulness, poor concentration, slowed thinking, and headaches. There was a significant positive association between symptom attribution and overall symptom endorsement (NSI total score) (r=0.675) and endorsement of specific symptom domains (NSI symptom domain scores) (r=0.506-0.674), indicating that greater attribution of symptoms to TBI was associated with greater symptom endorsement. Furthermore, linear regressions showed that symptom attribution was significantly associated with objective cognitive functioning, whereas symptom endorsement generally did not show this relationship. Specifically, greater attribution of symptoms to TBI was associated with worse executive functioning (ß=-0.34), attention and working memory (ß=-0.43), and processing speed (ß=-0.35). CONCLUSIONS: These findings suggest that veterans who routinely attribute neurobehavioral symptoms to their TBI are at greater risk of experiencing poor long-term outcomes, including elevated symptom endorsement and worse objective cognition. Although more research is needed to understand how illness perception influences outcomes in this population, these preliminary results highlight the importance of early psychoeducation regarding the anticipated course of recovery following TBI.
