It is a "small world": Relations between performance on five spatial tasks and five mathematical tasks in undergraduate students.

One of the most robust relations in cognition is that between spatial and mathematical reasoning. One important question is whether this relation is domain general or if specific relations exist between performance on different types of spatial tasks and performance on different types of mathematical tasks. In this study, we explore unique relations between performance on five spatial tasks and five mathematical tasks. An exploratory factor analysis conducted on Data Set 1 (N = 391) yielded a two-factor model, one spatial factor and one mathematical factor with significant cross-domain factor loadings. The general two-factor model structure was replicated in a confirmatory factor analysis conducted in a separate data set (N = 364) but the strength of the factor loadings differed by task. Multidimensional scaling and network-based analyses conducted on the combined data sets reveal one spatial cluster, with a central node and one more tightly interconnected mathematical cluster. Both clusters were interconnected via the math task assessing geometry and spatial sense. The unique links identified with the network-based analysis are representative of a "small-world network." These results have theoretical implications for our understanding of the spatial-mathematical relation and practical implications for our understanding of the limitations of transfer between spatial training paradigms and mathematical tasks.

Examining the Interplay between the Cognitive and Emotional Aspects of Gender Differences in Spatial Processing.

Women reliably perform worse than men on measures of spatial ability, particularly those involving mental rotation. At the same time, females also report higher levels of spatial anxiety than males. What remains unclear, however, is whether and in what ways gender differences in these cognitive and affective aspects of spatial processing may be interrelated. Here, we tested for robust gender differences across six different datasets in spatial ability and spatial anxiety (N = 1257, 830 females). Further, we tested for bidirectional mediation effects. We identified indirect relations between gender and spatial skills through spatial anxiety, as well as between gender and spatial anxiety through spatial skills. In the gender → spatial anxiety → spatial ability direction, spatial anxiety explained an average of 22.4% of gender differences in spatial ability. In the gender → spatial ability → spatial anxiety direction, spatial ability explained an average of 25.9% of gender differences in spatial anxiety. Broadly, these results support a strong relation between cognitive and affective factors when explaining gender differences in the spatial domain. However, the nature of this relation may be more complex than has been assumed in previous literature. On a practical level, the results of this study caution the development of interventions to address gender differences in spatial processing which focus primarily on either spatial anxiety or spatial ability until such further research can be conducted. Our results also speak to the need for future longitudinal work to determine the precise mechanisms linking cognitive and affective factors in spatial processing.

COVID-19 coverage from six network and cable news sources in the United States: Representation of misinformation, correction, and portrayals of severity.

The COVID-19 pandemic in the United States is marked by divisions in perceptions of disease severity as well as misperceptions about the virus and vaccine that vary along ideological and political party lines. Perceptual differences may be due to differences in the information about the virus that individuals are exposed to within their own identity-affirming ideological news bubbles. This content analysis of six different national network transcripts highlights differences in coverage of severity, and the prevalence of misinformation and its correction that are consistent with previously established preferred news channels of conservatives/Republicans and liberals/Democrats and their perceptions and misperceptions about the pandemic. Results contribute to the growing body of country-specific COVID-19 media studies that allow for comparisons across nations with different cultures and media systems, as these factors play a pivotal role in national responses and experiences.

Transcoding of French numbers for first- and second-language learners in third grade.

Transcoding is the process of translating between spoken and written numbers, and it is correlated with other mathematical skills. In the present study, we investigated the link between French number writing of 49 students in the third grade (aged 7-9 years) and their language skills. Transcoding in French is of particular interest because the spoken number language system does not completely correspond to that of the written digits (e.g., quatre-vingt-dix [four-twenty-ten] and 90). We hypothesised that the complex linguistic structure of spoken numbers in French would be challenging for students who are learning to transcode. First and second French-language learners' accuracy and errors were recorded during a writing task of 3- to 7-digit numbers. Children also completed linguistic tests (e.g., receptive vocabulary, receptive syntax). Results showed that first- and second-language learners did not differ in their transcoding accuracy. Number size, decade complexity of stimulus number words in French (i.e., numbers containing a complex decade, operationalized as a number between soixante-dix, 70, and quatre-vingt-dix-neuf, 99), and receptive vocabulary predicted children's French transcoding skills. Students were more likely to produce errors (e.g., 68 or 6018 for 78) when they transcoded complex decade numbers compared with simple decade numbers. When an error was made on the complex decade portion of a number, it was likely a lexical error. In conclusion, third graders, both first- and second-language learners, found complex decade numbers challenging and their performance was related to their general vocabulary skills.

Assessment of the contribution of surfactants to mixture toxicity in French surface waters.

Surfactants are widely used 'down-the-drain' chemicals with the potential to occur at high concentrations in local water bodies and to be part of unintentional environmental mixtures. Recently, increased regulatory focus has been placed on the impacts of complex mixtures in aquatic environments and the substances that are likely to drive mixture risk. This study assessed the contribution of surfactants to the total mixture pressure in freshwater ecosystems. Environmental concentrations, collated from existing French monitoring data, were combined with estimated ecotoxicological thresholds to calculate hazard quotients (HQ) for each substance, and hazard indices (HI) for each mixture. Two scenarios were investigated to correct for concentrations below the limit of quantification (LOQ) in the dataset. The first (best-case) scenario assumed all values

Comparison of in silico, in vitro, and in vivo toxicity benchmarks suggests a role for ToxCast data in ecological hazard assessment.

Large repositories of in vitro bioactivity data such as US EPA's Toxicity Forecaster (ToxCast) provide a wealth of publicly accessible toxicity information for thousands of chemicals. These data can be used to calculate point-of-departure (POD) estimates via concentration-response modeling that may serve as lower bound, protective estimates of in vivo effects. However, the data are predominantly based on mammalian models and discussions to date about their utility have largely focused on potential integration into human hazard assessment, rather than application to ecological risk assessment. The goal of the present study was to compare PODs based on (1) quantitative structure-activity relationships (QSARs), (2) the 5th centile of the activity concentration at cutoff (ACC), and (3) lower-bound cytotoxic burst (LCB) from ToxCast, with the distribution of in vivo PODs compiled in the Ecotoxicology Knowledgebase (ECOTOX). While overall correlation between ToxCast ACC5 and ECOTOX PODs for 649 chemicals was weak, there were significant associations among PODs based on LCB and ECOTOX, LCB and QSARs, and ECOTOX and QSARs. Certain classes of compounds showed moderate correlation across datasets (eg, antimicrobials/disinfectants), while others, such as organophosphate insecticides, did not. Unsurprisingly, more precise classifications of the data based on ECOTOX effect and endpoint type (eg, apical vs biochemical; acute vs chronic) had a significant effect on overall relationships. Results of this research help to define appropriate roles for data from new approach methodologies in chemical prioritization and screening of ecological hazards.

Parental intrusive homework support and math achievement: Does the child's mindset matter?

Prior research shows that when parents monitor, check, and assist in completing homework without an invitation, their children's motivation and academic achievement often decline. We propose that intrusive support from parents might also send the message that children are incompetent, especially if they believe their intelligence is fixed. We tested whether children's mindsets moderate the negative link between parents' intrusive homework support and achievement among first- and second-grade students followed for one academic year (Study 1, N = 563) and middle and high school students for two academic years (Study 2, N = 1,613). The samples were obtained from large urban areas in the United States. In both studies, intrusive homework support more strongly predicted a decrease in achievement over time for children with a fixed mindset. These findings suggest that the belief that intellectual ability cannot be changed may exacerbate the detrimental effects of uninvited help on academic work.

Urban Youth Perceptions of Sports and Energy Drinks: Insights for Health Promotion Messaging.

Objective: This study aimed to examine urban adolescents' beliefs about sports and energy drinks to identify factors for health messaging to discourage youth consumption. Design: Focus group study involving thirty-four adolescents in urban areas (12 female, 12 male, and 10 unreported sex; 19 Hispanic, 11 Non-Hispanic Black, 2 Asian, and 1 unknown race or ethnicity). Setting: Four focus groups were conducted with adolescents in urban areas. Method: Each on-time moderated group discussion was structured to generate an inventory of attitudinal, normative and efficacy beliefs associated with sports and energy drink consumption and reduction. Thematic analysis was used to analyse the data. Results: Attitudinal and normative beliefs were more positive towards sports drink consumption and energy drink reduction. Misperceptions about the need for sports drinks to avoid dehydration during physical activity were evident. Product accessibility and advertising pervasiveness were facilitators influencing consumption and barriers to reduction for both products. Conclusion: Results highlight important differences in perceptions about sports and energy drinks that indicate the need for different approaches and messages for interventions designed to curb consumption of these products. Recommendations for message design are provided.

How intention to join an Alzheimer's participant recruitment registry differs by race, ethnicity, sex, and family history: Results from a national survey of US adults.

INTRODUCTION: Alzheimer's-focused participant recruitment registries are tools for accelerating enrollment into studies, however, registry members are primarily White women. METHODS: We conducted a national online survey of 1501 adults ages 50-80, oversampling for Black and Hispanic/Latino respondents, assessing intention to join a generic "brain health" registry and to join a registry that required specific tasks. RESULTS: Intention to join a registry was low (M 3.48, SD 1.77), and lower than intention to join a registry requiring specific tasks. Intention was greatest for registries requiring completing surveys (M 4.70, SD 1.77). Differences in intention were primarily between White women and Black women; differences between other groups were limited to specific tasks required. DISCUSSION: The results indicate uncertainty about what a registry is, its purpose, and/or the concept of "brain health." Using the Reasoned Action Approach (RAA) to develop evidence-based outreach messages describing a registry and required tasks may increase diversity.

Evaluation of Complex Mixture Toxicity in the Milwaukee Estuary (WI, USA) Using Whole-Mixture and Component-Based Evaluation Methods.

Anthropogenic activities introduce complex mixtures into aquatic environments, necessitating mixture toxicity evaluation during risk assessment. There are many alternative approaches that can be used to complement traditional techniques for mixture assessment. Our study aimed to demonstrate how these approaches could be employed for mixture evaluation in a target watershed. Evaluations were carried out over 2 years (2017-2018) across 8-11 study sites in the Milwaukee Estuary (WI, USA). Whole mixtures were evaluated on a site-specific basis by deploying caged fathead minnows (Pimephales promelas) alongside composite samplers for 96 h and characterizing chemical composition, in vitro bioactivity of collected water samples, and in vivo effects in whole organisms. Chemicals were grouped based on structure/mode of action, bioactivity, and pharmacological activity. Priority chemicals and mixtures were identified based on their relative contributions to estimated mixture pressure (based on cumulative toxic units) and via predictive assessments (random forest regression). Whole mixture assessments identified target sites for further evaluation including two sites targeted for industrial/urban chemical mixture effects assessment; three target sites for pharmaceutical mixture effects assessment; three target sites for further mixture characterization; and three low-priority sites. Analyses identified 14 mixtures and 16 chemicals that significantly contributed to cumulative effects, representing high or medium priority targets for further ecotoxicological evaluation, monitoring, or regulatory assessment. Overall, our study represents an important complement to single-chemical prioritizations, providing a comprehensive evaluation of the cumulative effects of mixtures detected in a target watershed. Furthermore, it demonstrates how different tools and techniques can be used to identify diverse facets of mixture risk and highlights strategies that can be considered in future complex mixture assessments.

A framework for prioritizing contaminants in retrospective ecological assessments: Application in the Milwaukee Estuary (Milwaukee, WI).

Watersheds are subjected to diverse anthropogenic inputs, exposing aquatic biota to a wide range of chemicals. Detection of multiple, different chemicals can challenge natural resource managers who often have to determine where to allocate potentially limited resources. Here, we describe a weight-of-evidence framework for retrospectively prioritizing aquatic contaminants. To demonstrate framework utility, we used data from 96-h caged fish studies to prioritize chemicals detected in the Milwaukee Estuary (WI, USA; 2017-2018). Across study years, 77/178 targeted chemicals were detected. Chemicals were assigned prioritization scores based on spatial and temporal detection frequency, environmental distribution, environmental fate, ecotoxicological potential, and effect prediction. Chemicals were sorted into priority bins based on the intersection of prioritization score and data availability. Data-limited chemicals represented those that did not have sufficient data to adequately evaluate ecotoxicological potential or environmental fate. Seven compounds (fluoranthene, benzo[a]pyrene, pyrene, atrazine, metolachlor, phenanthrene, and DEET) were identified as high or medium priority and data sufficient and flagged as candidates for further effects-based monitoring studies. Twenty-one compounds were identified as high or medium priority and data limited and flagged as candidates for further ecotoxicological research. Fifteen chemicals were flagged as the lowest priority in the watershed. One of these chemicals (2-methylnaphthalene) displayed no data limitations and was flagged as a definitively low-priority chemical. The remaining chemicals displayed some data limitations and were considered lower-priority compounds (contingent on further ecotoxicological and environmental fate assessments). The remaining 34 compounds were flagged as low or medium priority. Altogether, this prioritization provided a screening-level (non-definitive) assessment that could be used to focus further resource management and risk assessment activities in the Milwaukee Estuary. Furthermore, by providing detailed methodology and a practical example with real experimental data, we demonstrated that the proposed framework represents a transparent and adaptable approach for prioritizing contaminants in freshwater environments.

Perceptions of Sports and Energy Drinks: Factors Associated with Adolescent Beliefs.

PURPOSE: To understand what factors are associated with adolescents' perceived healthfulness of sports drinks (SD) and of energy drinks (ED), with a focus on health risk, athletics, and media-related variables. DESIGN: Cross-sectional survey. SETTING: Online. SUBJECTS: U.S. adolescents ages 14-18 years (n = 501) recruited from a combination of non-probability and probability-based panels. MEASURES: Outcome variables were perceived healthfulness of SDs and of EDs. Independent variables included adolescents' health background (oral health, diabetes risk, self-reported weight); behaviors (SD and ED consumption, athletic identity, sports participation, physical activity), and media items (media literacy, exposure to advertisements on TV, YouTube, social media). RESULTS: Regression results indicated that adolescents' increased perception that SDs are healthy was significantly associated (P<.05 level) with casual sports participation (b=.56, se=.27), athletic identification (b=.28, se= .11), exposure to SD advertisements on social media (b=.55, s =.25), and higher consumption (b=.28, se= .13). For adolescents' perceptions of EDs, significantly related correlates included athletic identification (b=.26, se=10), having an increased risk of diabetes (b= -.79, s =.26), poorer oral health (b=.33, se=.16), and consumption (b=.76, s =.16); increased media literacy was associated with more accurate perceptions (b=-.35, se=.14). CONCLUSIONS: Adolescents' hold different perceptions about the healthfulness of sports and energy drink, and their beliefs about each drink are related to different types of factors that may have implications for public health interventions. Cross-sectional survey design and adolescent self-reports are limitations.

Athletes Drink Gatorade: DMA Advertising Expenditures, Ad Recall, and Athletic Identity Influence Energy and Sports Drink Consumption.

Understanding why sports and energy drinks remain increasingly popular among adolescents despite declines in other sugar sweetened beverages is critical. This study points to memory for advertising exposure and adolescent athletic identity as two aspects that together help to explain consumption. An online survey of U.S. adolescents aged 14-18 (n = 503) was combined with Nielsen data for television and social media advertising expenditures by sports and energy drink brands in participants' designated market areas (DMAs). Advertisement recall mediates the relationship between social media DMA expenditures and sports and energy drink consumption. Recall for television advertisements is related to consumption but is unrelated to television DMA expenditures. Athletic identity moderated the relationship between recall and consumption such that consumption increased as both recall and athletic identity increased, suggesting a role for motivated memory and motivated processing of ad messages based on athletic identity consistent with the limited capacity model of motivated media message processing. Based on these results, we conclude that effectiveness of expenditures in influencing behavior is dependent upon both ad recall and ad relevance, and that athletic identity is an important factor in ad effectiveness in the context of sports and energy drinks advertising.

Television News Media Consumption and Misperceptions about COVID-19 among US Populations at High Risk for Severe Health Outcomes Early in the Pandemic.

Research indicates that misperceptions that become part of people's initial mental models about an issue tend to persist and influence their attitudes even after the misperception has been corrected. Recent work on evolving mental models suggests that communication efforts about the ongoing COVID-19 pandemic and its aftermath may be improved by crafting messages that acknowledge biases and misunderstandings about the virus and other infectious diseases that may remain among members of the target audience. This study was designed to provide insight into such biases by: (1) establishing salient categories of COVID-related misperceptions in the earliest months of the pandemic in the United States among (a) the general population, and (b) demographic sub-populations at high risk of severe health outcomes; (2) identifying demographic predictors of misperceptions; and (3) examining the relationship between consumption of different television news outlets and agreement with misperceptions about COVID-19. A national sample of 1,000 adults in the United States (48.1% male; M age = 47.32, SD = 18.01; 72.9% White/Caucasian, 14.3% Black/African American, 15.9% Hispanic/Latinx) completed a survey between March 19 and March 25, 2020. Results identify prevalent classes of salient early COVID-19 misperceptions. Adjusting for numerous covariates, data indicated individuals over the age of 60 held the fewest COVID-related misperceptions among various demographic sub-populations, misperceptions were most prevalent among Black respondents, and increased consumption of television network news was associated with lower levels of misperception. Consumption of some 24-hour news networks (FOX and MSNBC) were significant positive correlates of misperceptions.

Reducing Unhealthy Normative Behavior: The Case of Sports and Energy Drinks.

American adolescents consume more sugar-sweetened beverages (SSBs) than any other age group. Sports and energy drinks consumption among adolescents is higher than other SSBs. For sports drinks, there is uncertainty about their "healthiness" and also beliefs that these drinks may provide health benefits such as hydration, enhanced athletic performance, heightened mental alertness, and rapid recovery after exercise. Confusion about relative healthiness and expectations of health benefits suggest that factors that may encourage youth to avoid drinking sports and energy drinks, such as athletic status, psychological reactance, and SSB media literacy, may necessitate different approaches to promoting avoidance of sports drinks compared with avoidance of energy drinks. Using a nationally representative U.S. probability-based web panel augmented by a volunteer nonprobability-based web panel of 500 adolescent participants aged 14 to 18 years, we used the reasoned action approach to model intention to avoid sports and to avoid energy drinks. The result show there are similarities and differences in the determinants associated with adolescents' avoidance of sports and energy drinks: attitudes and descriptive normative pressure are both related to increased avoidance for both types of drinks and perceived control over the avoidance behavior is positively associated for with intention to avoid for energy drinks. Sport identification, psychological reactance, and SSB media literacy also play a different role in the sports and energy drink models. Based on our results, the content of prevention messages in interventions to limit sports drinks will need to be quite different from those targeted at reducing energy drink consumption.

Factors associated with COVID-19 masking behavior: an application of the Health Belief Model.

Wearing a face mask is effective in minimizing the spread of coronavirus disease 2019 (COVID-19) among unvaccinated individuals and preventing severe illness among the vaccinated. Country, state and local guidelines promote, and at times mandate, mask-wearing despite it being publicly perceived as an individual's choice. Guided by the Health Belief Model (HBM), structural equation modeling was used to analyze longitudinal data in a sample of US adults aged 18-49 years to identify constructs that contribute to face mask-wearing. Results indicated that perceived COVID-19 severity, perceived masking benefits and self-efficacy were positively associated with masking behavior, and masking barriers were negatively associated with masking behavior. Perceived susceptibility to COVID-19 and cues to action were nonsignificant correlates of masking behavior. These results' theoretical and practical implications contribute to the literature on the HBM and the COVID-19 pandemic. Future directions and limitations are discussed.

An Elicitation Study to Understand Black, Hispanic, and Male Older Adults' Willingness to Participate in Alzheimer's Disease-Focused Research Registries.

BACKGROUND: There is a lack of racial, ethnic, and sex diversity in recruitment research registries and Alzheimer's disease (AD) research studies and trials. Theory-based recruitment messages may provide an opportunity to increase study participant diversity in AD research studies and trials. OBJECTIVE: To identify behavioral, normative, and control beliefs that are associated with joining an AD-focused recruitment registry among historically underrepresented groups. METHOD: Using a Reasoned Action Approach, we conducted 60 semi-structured phone interviews in 2020 among White, Black, and Hispanic adults ages 49-79 years in Philadelphia, PA. Underlying beliefs were elicited for the target behavior of "signing up to be on a registry for brain health research studies in the next month." Percentages based on counts are reported for the overall sample and by race and ethnicity and sex. RESULTS: Participants were most concerned that if they were to sign up for a registry, they would be asked to participate in experimental studies. Advancing science to help others was a commonly reported positive belief about signing up. Participants' children and friends/neighbors were important from a normative perspective. Barriers to enrollment focused on logistical concerns and inconvenient sign-up processes, including using a computer. Results show generally few racial and ethnic or sex group differences. CONCLUSION: The elicited beliefs from underrepresented groups offer a basis for understanding the behavior of signing up for research registries. However, there were few differences between the groups. Implications for outreach and recruitment are discussed.

Appraisals of previous math experiences play an important role in math anxiety.

Math anxiety affects many people, from young children through to older adults. While there has been debate concerning the developmental trajectory of math anxiety and negative math attitudes, little attention has been given to the role of appraisals of previous math experiences. We surveyed 308 adults (mean age = 27.56 years, SD = 11.25) and assessed self-reported measures of math anxiety, mathematical resilience, math attitudes, and appraisal of previous math experiences. As hypothesized, all variables were found to be interrelated. Math anxiety was significantly negatively related to appraisal of previous math experiences, mathematical resilience, and math attitudes. Moreover, appraisal of previous math experiences was shown to mediate the relations between (1) math anxiety and math attitudes, and (2) mathematical resilience and math attitudes. The findings demonstrate the importance of considering current appraisals of previous math experiences and are consistent with an interpretation account of math anxiety. This may help inform cognitive-based interventions that focus on one's interpretation of past events to support current and future math learning and engagement.

Linking Mechanistic Effects of Pharmaceuticals and Personal Care Products to Ecologically Relevant Outcomes: A Decade of Progress.

There are insufficient toxicity data to assess the ecological risks of many pharmaceuticals and personal care products (PPCPs). While data limitations are not uncommon for contaminants of environmental concern, PPCPs are somewhat unique in that an a priori understanding of their biological activities in conjunction with measurements of molecular, biochemical, or histological responses could provide a foundation for understanding mode(s) of action and predicting potential adverse apical effects. Over the past decade significant progress has been made in the development of new approach methodologies (NAMs) to efficiently quantify these types of endpoints using computational models and pathway-based in vitro and in vivo assays. The availability of open-access knowledgebases to curate biological response (including NAM) data and sophisticated bioinformatics tools to help interpret the information also has significantly increased. Finally, advances in the development and implementation of the adverse outcome pathway framework provide the critical conceptual underpinnings needed to translate NAM data into predictions of the ecologically relevant outcomes required by risk assessors and managers. The evolution and convergence of these various data streams, tools, and concepts provides the basis for a fundamental change in how ecological risks of PPCPs can be pragmatically assessed.

Co-occurring OCD and Panic Disorder: A Review of Their Etiology and Treatment.

Estimated rates of co-occurrence between obsessive and compulsive disorder (OCD) and panic disorder (PD) are notable, but vary considerably, with rates from epidemiological and clinical studies ranging from 1.8% to 22% (Rector et al., 2017). We reviewed the current empirical literature on the etiology, treatment, diagnostic assessment, and differential diagnosis of co-occurring OCD/PD. Best practices for cognitive-behavioral treatment, including identifying and addressing treatment barriers are also addressed. Although it is acknowledged in current literature that co-occurring OCD and PD levels may be clinically significant, there remains a need to thoroughly examine the possible consequences and future research directions of this overlap. Future research must continue to elucidate the biological and environmental causes of OCD/PD co-occurrence.
