Effects of physically active maths lessons on children's maths performance and maths-related affective factors: Multi-arm cluster randomized controlled trial.

BACKGROUND: Physical activity (PA) may benefit academic performance, but it is unclear what kind of classroom-based PA is optimal for learning. AIM: We studied the effects of physically active maths lessons on children's maths performance and maths-related effects, and whether gender and previous mathematical or motor skills modify these effects. SAMPLE: A total of 22 volunteered teachers and their pupils with signed consent (N = 397, mean age: 9.3 years, 51% females) participated in a 5-month, teacher-led, multi-arm, cluster-randomized controlled trial. METHODS: The intervention included a PAL group (20 min of physically active learning in each 45-min lesson), a breaks group (two 5-min PA breaks in each 45-min lesson) and a control group (traditional teaching). Maths performance was assessed with a tailored curriculum-based test. Maths-related enjoyment, self-perceptions and anxiety were measured with a self-reported questionnaire. The individual-level intervention effects were tested via covariate-adjusted linear mixed-effect models with school classes serving as random effects. RESULTS: Changes in maths performance or self-perceptions did not differ between the intervention groups. Maths anxiety in learning situations increased in the PAL group (effect .28, 95% CI = .01-.56); there was no change in the other groups. Subgroup analyses suggested that maths anxiety increased in the PAL group among children in the two lowest tertiles of motor skills. It decreased in the highest tertile. Enjoyment decreased in the breaks group among pupils in the lowest motor skill tertile. CONCLUSIONS: Physically active maths lessons did not affect maths performance or self-perceptions but had divergent effects on maths anxiety and enjoyment, depending on motor skills.

Defending Others Online: The Influence of Observing Formal and Informal Social Control on One's Willingness to Defend Cyberhate Victims.

This paper examines factors correlated with online self-help-an informal form of social control vis-à-vis intervention-upon witnessing a cyberhate attack. Using online surveys from 18- to 26-year-old respondents in the United States, we explore the roles of various types of online and offline formal and informal social control mechanisms on the enactment of self-help through the use of descriptive statistics and ordinal logistic regression. The results of the multivariate analyses indicate that online collective efficacy is positively related to self-help, as is having close ties to individuals and groups offline and online. Formal online social control, however, is not significantly related to engaging in self-help. Other findings demonstrate that personal encounters with cyberhate affect the likelihood that an individual will intervene when witnessing an attack, and that individuals with high levels of empathy are more likely to intervene to assist others. This work indicates that pro-social online behavior is contagious and can potentially foster online spaces in which harmful behaviors, such as propagating cyberhate, are not condoned.

Subtypes of mathematical learning disability and their antecedents: A cognitive diagnostic approach.

Using cognitive diagnostic modeling (CDM), this study identified subtypes of mathematics learning disability (MLD) based on children's numerical skills and examined the language and spatial precursors of these subtypes. Participants were 99 MLD children and 420 low achievers identified from 1839 Finnish children (966 boys) who were followed from preschool (age 6) to fourth grade (2007-2011). Five subtypes were identified: the arithmetic fluency deficit only subtype, the counting deficit subtype, the pervasive deficit subtype, the symbolic deficit subtype, and the counting and concept deficit subtype. Different subtypes depended on different constellations of language and spatial deficits. Findings highlight the effectiveness of CDM in identifying MLD subtypes and underscore the importance of understanding the specific deficits and antecedents of the subtypes.

Factors Associated with Online Hate Acceptance: A Cross-National Six-Country Study among Young Adults.

The Internet, specifically social media, is among the most common settings where young people encounter hate speech. Understanding their attitudes toward the phenomenon is crucial for combatting it because acceptance of such content could contribute to furthering the spread of hate speech as well as ideology contamination. The present study, theoretically grounded in the General Aggression Model (GAM), investigates factors associated with online hate acceptance among young adults. We collected survey data from participants aged 18-26 from six countries: Finland (n = 483), France (n = 907), Poland (n = 738), Spain (n = 739), the United Kingdom (n = 959), and the United States (n = 1052). Results based on linear regression modeling showed that acceptance of online hate was strongly associated with acceptance of violence in all samples. In addition, participants who admitted to producing online hate reported higher levels of acceptance of it. Moreover, association with social dominance orientation was found in most of the samples. Other sample-specific significant factors included participants' experiences with the Internet and online hate, as well as empathy and institutional trust levels. Significant differences in online hate acceptance levels and the strength of its connections to individual factors were found between the countries. These results provide important insights into the phenomenon, demonstrating that online hate acceptance is part of a larger belief system and is influenced by cultural background, and, therefore, it cannot be analyzed or combatted in isolation from these factors.

Cybercrime Victimization and Problematic Social Media Use: Findings from a Nationally Representative Panel Study.

According to criminological research, online environments create new possibilities for criminal activity and deviant behavior. Problematic social media use (PSMU) is a habitual pattern of excessive use of social media platforms. Past research has suggested that PSMU predicts risky online behavior and negative life outcomes, but the relationship between PSMU and cybercrime victimization is not properly understood. In this study, we use the framework of routine activity theory (RAT) and lifestyle-exposure theory (LET) to examine the relationship between PSMU and cybercrime victimization. We analyze how PSMU is linked to cybercrime victimization experiences. We explore how PSMU predicts cybercrime victimization, especially under those risky circumstances that generally increase the probability of victimization. Our data come from nationally representative surveys, collected in Finland in 2017 and 2019. The results of the between-subjects tests show that problematic PSMU correlates relatively strongly with cybercrime victimization. Within-subjects analysis shows that increased PSMU increases the risk of victimization. Overall, the findings indicate that, along with various confounding factors, PSMU has a notable cumulative effect on victimization. The article concludes with a short summary and discussion of the possible avenues for future research on PSMU and cybercrime victimization.

How physical activity, fitness, and motor skills contribute to math performance: Working memory as a mediating factor.

PURPOSE: The purpose of this study was to examine whether physical activity, fitness, and motor skills have an indirect association with math performance via cognitive outcomes and if so, through which aspects of cognition? METHODS: This study comprised 311 6th-9th grade adolescents (12-17 years [M age = 14.0 years], 59% girls) from seven schools throughout Finland in 2015. Math performance was measured via a teacher-rated math achievement and the Basic Arithmetic test. Cognitive functions were measured by broad cognitive test battery. Physical activity was assessed with a self-reported questionnaire and a hip-worn accelerometer. Aerobic fitness was estimated using a maximal 20-m shuttle run test, muscular fitness with curl-up and push-up tests, and motor skills with a 5-leaps test and a throwing-catching combination test. Structural equation modeling was applied to examine the associations. RESULTS: In both boys and girls, motor skills had a positive indirect association with math outcomes through visuospatial working memory. Among girls, muscular fitness had a positive indirect association with math outcomes through visuospatial working memory. Aerobic fitness was positively associated with math achievement, but the indirect path via cognition was not observed. Self-reported physical activity had a borderline indirect positive association with math outcomes through visuospatial working memory. Accelerometer-based physical activity did not correlate with math performance. CONCLUSION: Motor skills and muscular fitness had indirect positive associations with math performance, mediated by visuospatial working memory. The results give support to the viewpoints that the connections between motor skills, fitness, and physical activity to academic skills are mediated via specific cognitive skills.

Early Cognitive Precursors of Children's Mathematics Learning Disability and Persistent Low Achievement: A 5-Year Longitudinal Study.

Mathematical difficulties have been distinguished as mathematics learning disability (MLD) and persistent low achievement (LA). Based on 1,880 Finnish children who were followed from kindergarten (age 6) to fourth grade, this study examined the early risk factors for MLD and LA. Distinct groups of MLD (6.0% of the sample) and LA (25.7%) children were identified on the basis of their mathematics performance between first and fourth grades with latent class growth modeling. Impairment in the same set of cognitive skills, including language, spatial, and counting skills, was found to underlie MLD and LA. The finding highlights the importance of monitoring mathematical development across the early grades and identifying early cognitive precursors of MLD and LA for screening and intervention efforts.

Cognitive-Linguistic and Constructivist Mnemonic Triggers in Teaching Based on Jerome Bruner's Thinking.

Effective teachers use mnemonic tools or mnemonic triggers to improve the students' retention of the study material. This article discusses mnemonic triggers from a theoretical viewpoint based on Jerome S. Bruner's writings. Fifty small linguistic-cognitive, constructive-, rhetorical-, and phonological-mnemonic triggers are detected. These triggers may become supporting elements for our memory system when we are "constructing the realities" in a Brunerian sense when we are ordering, differentiating, comparing, and handling information, stories and experiences in our mind. Many of these are small, hidden linguistic elements in speech. This article discusses their usage in the educational talk and textbooks.

Cybercrime Victimization and Subjective Well-Being: An Examination of the Buffering Effect Hypothesis Among Adolescents and Young Adults.

The wealth of beneficial tools for online interaction, consumption, and access to others also bring new risks for harmful experiences online. This study examines the association between cybercrime victimization and subjective well-being (SWB) and, based on the buffering effect hypothesis, tests the assumption of the protective function of social belonging in cybercrime victimization. Cross-national data from the United States, United Kingdom, Germany, and Finland (N = 3,557; Internet users aged 15-30 years; 49.85 percent female) were analyzed using descriptive statistics and main and moderation effect models. Results show that cybercrime victimization has a negative association with SWB after adjusting for a number of confounding factors. This association concerns both general cybercrime victimization and subcategories such as victimization to offensive cybercrime and cyberfraud. In line with the buffering effect hypothesis, social belonging to offline groups was shown to moderate the negative association between SWB and cybercrime victimization. The same effect was not found in the social belonging to online groups. Overall, the study indicates that, analogously to crime victimization in the offline context, cybercrime is a harmful experience whose negative effects mainly concern those users who have weak social ties offline to aid in coping with such stressors.

Knowing, applying, and reasoning about arithmetic: Roles of domain-general and numerical skills in multiple domains of arithmetic learning.

The longitudinal relations of domain-general and numerical skills at ages 6-7 years to 3 cognitive domains of arithmetic learning, namely knowing (written computation), applying (arithmetic word problems), and reasoning (arithmetic reasoning) at age 11, were examined for a representative sample of 378 Finnish children. The results showed that domain-general skills, including spatial visualization, language, rapid automatized naming, and working memory, contributed independently to arithmetic learning. These relations were mostly mediated via basic number competence (i.e., counting sequence and number system knowledge), although spatial visualization remained predictive of arithmetic outcomes. The findings underscore a similar developmental course of arithmetic learning across different cognitive domains where domain-general skills build a launchpad for advanced arithmetic via enhancing basic number competence.

Proeating disorder websites and subjective well-being: A four-country study on young people.

OBJECTIVE: Proeating disorder (pro-ED) communities online encourage harmful weight-loss and weight-control practices. This study examined the association between exposure to pro-ED content online and subjective well-being (SWB) among adolescents and young adults in four countries. METHOD: Cross-national data were collected in the US, Germany, the UK and Finland from Internet users aged 15-30 years (N = 3,557; 50.15% male). The questionnaire assessed SWB, exposure to harm-advocating websites, online activity, prior victimization, and social belonging. Ordinary least squares (OLS) regression models assessed the relationship between SWB and pro-ED exposure and adjusted for a number of confounding factors. RESULTS: Of the participants, 17% had been exposed to pro-ED content (US 20%, Germany 7%, UK 21%, Finland 22%). Exposure to pro-ED content online was negatively associated with SWB in the US, Germany, and Finland, also after adjusting for the confounding factors. Offline social belonging moderated the association between pro-ED and SWB. DISCUSSION: Participants who visited pro-ED websites reported lower SWB than others did. The potentially harmful impact of visiting these sites was buffered by the strong offline social belonging. Given the observed similarities across the countries, it is important for families, health professionals, and educators to stay abreast of online communities that have possible contra recovery influences and to be able to discuss such Internet contents in a way that increases treatment motivation. © 2016 Wiley Periodicals, Inc.

Victimization and Exposure to Pro-Self-Harm and Pro-Suicide Websites: A Cross-National Study.

The study of websites displaying methods of both physical self-harm and suicide has become an important aspect of deliberate self-injury and suicide research. However, little is known about contextual factors related to entering such sites. Using data from 3,567 respondents aged 15-30 in the US, UK, Germany, and Finland, we found that experiences of victimization are associated with entering pro-self-harm sites and pro-suicide sites. Also, the victimization context had relevance, as online victimization was particularly related to pro-self-harm behavior. The findings suggest a need to organize more specific online support for the victims of violence and online aggression.

Behavior and neuroimaging at baseline predict individual response to combined mathematical and working memory training in children.

Mathematical performance is highly correlated with several general cognitive abilities, including working memory (WM) capacity. Here we investigated the effect of numerical training using a number-line (NLT), WM training (WMT), or the combination of the two on a composite score of mathematical ability. The aim was to investigate if the combination contributed to the outcome, and determine if baseline performance or neuroimaging predict the magnitude of improvement. We randomly assigned 308, 6-year-old children to WMT, NLT, WMT+NLT or a control intervention. Overall, there was a significant effect of NLT but not WMT. The WMT+NLT was the only group that improved significantly more than the controls, although the interaction NLTxWM was non-significant. Higher WM and maths performance predicted larger benefits for WMT and NLT, respectively. Neuroimaging at baseline also contributed significant information about training gain. Different individuals showed as much as a three-fold difference in their responses to the same intervention. These results show that the impact of an intervention is highly dependent on individual characteristics of the child. If differences in responses could be used to optimize the intervention for each child, future interventions could be substantially more effective.

Targets of Online Hate: Examining Determinants of Victimization Among Young Finnish Facebook Users.

Drawing from routine activity theory (RAT), this article seeks to determine the crucial factors contributing to youth victimization through online hate. Although numerous studies have supported RAT in an online context, research focusing on users of particular forms of social media is lacking. Using a sample of 15- to 18-year-old Finnish Facebook users (n = 723), we examine whether the risk of online hate victimization is more likely when youth themselves produced online hate material, visited online sites containing potentially harmful content, and deliberately sought out online hate material. In addition, we examine whether the risk of victimization is higher if respondents are worried about online victimization and had been personally victimized offline. The discussion highlights the accumulation of online and offline victimization, the ambiguity of the roles of victims and perpetrators, and the artificiality of the division between the online and offline environments among young people.

Two dimensions of trust in physicians in OECD-countries.

PURPOSE: The purpose of this paper is to analyse citizens' trust in physicians in 22 OECD countries. DESIGN/METHODOLOGY/APPROACH: The authors measure trust in physicians using items on generalised and particularised trust. Individual-level data are received from the ISSP Research Group (2011). The authors also utilise macro variables drawn from different data banks. Data were analysed using descriptive statistics and xtlogit regression models. The main micro-level hypothesis is that low self-reported health is strongly associated with lower trust in physicians. The second micro-level hypothesis is that frequent meetings with physicians result in higher trust. The third micro-level hypothesis assumes that males, and older and better educated respondents, express higher trust compared to others. The first macro-level hypothesis is that lower income inequality leads to higher trust in physicians. The second macro-level hypothesis is that greater physician density leads to higher trust in physicians. FINDINGS: The authors found that the influence of individual and macro-level characteristics varies between trust types. Results indicate that both trust types are clearly associated with individual-level determinants. However, only general trust in physicians has weak associations with macro-level indicators (mainly physician density) and therefore on institutional cross-country differences. It seems that particularised trust in a physician's skills is more restricted to the individuals' health and their own experiences meeting doctors, whereas general trust likely reflects attitudes towards the prevalent profession in the country. ORIGINALITY/VALUE: The findings hold significance for healthcare systems research and for research concerning social trust generally.

Consumer consciousness on meat and the environment - Exploring differences.

Global environmental challenges require changes in both the production and the consumption of goods. In this paper we analyse how consumers perceive the high environmental burden of meat. We analysed consumer environmental consciousness, including problem awareness and a support to action dimensions, latter including perceived self-efficacy as well as solutions to problems. The solutions were positioned on a continuum from increasing the efficiency of production to discussing sufficiency levels in consumption practices (techno-optimism, local meat, organic meat and meat reduction, respectively). We used a statistically representative survey sample (n = 1890) from the population of Finland and cluster analysis to explore differences among consumers. The analysis revealed that most Finns seem to be rather unsure of the study topic. At the same time they tend to have a comparably high level of self-efficacy (55 per cent of respondents) and endorsement of particularly local meat solution type (55%), followed by organic meat (35%), meat reduction (25%) and techno-optimism (15%), though the neutral stand was the most common one across the data. We also identified six consumer groups that reveal not only a high number of Highly unsure consumers (40%), but also some Rather conscious (20%) and a relatively small number of Highly conscious (8%). In addition, there were also easily observable groups of Careless conscious (14%), Rather unsure (9%) and Resistant (8%). The results highlight the need for a multitude of political actions to guide meat consumption, as there are groups that may benefit from practical tools for making dietary changes as well as groups in need for more comprehensive selection of measures, including environmental information.

Does Social Belonging to Primary Groups Protect Young People From the Effects of Pro-Suicide Sites?

BACKGROUND: The Internet has facilitated the existence of extreme and pathological communities that share information about ways to complete suicide or to deliberately harm or hurt oneself. This material is user-generated and easily accessible. AIMS: The present study analyzed the buffering effect of social belonging to a primary group in the situation of pro-suicide site exposure. METHOD: Cross-national data were collected from the US, UK, Germany, and Finland in spring 2013 and 2014 from respondents aged 15-30 years (N = 3,567). Data were analyzed by using linear regression separately for women and men for each country. RESULTS: A higher level of belonging to a primary group buffered the negative association of pro-suicide site exposure with mental health, measured as happiness, although the results were not consistent in the subgroups. US male subjects showed a significant buffering effect of the sense of belonging to family while the belonging to friends had a buffering effect among four other subgroups: British female and male subjects and Finnish female and male subjects. CONCLUSION: The results underline the positive potential of primary groups to shield young people's mental health in the situation of pro-suicide site exposure.

Pro-Anorexia and Anti-Pro-Anorexia Videos on YouTube: Sentiment Analysis of User Responses.

BACKGROUND: Pro-anorexia communities exist online and encourage harmful weight loss and weight control practices, often through emotional content that enforces social ties within these communities. User-generated responses to videos that directly oppose pro-anorexia communities have not yet been researched in depth. OBJECTIVE: The aim was to study emotional reactions to pro-anorexia and anti-pro-anorexia online content on YouTube using sentiment analysis. METHODS: Using the 50 most popular YouTube pro-anorexia and anti-pro-anorexia user channels as a starting point, we gathered data on users, their videos, and their commentators. A total of 395 anorexia videos and 12,161 comments were analyzed using positive and negative sentiments and ratings submitted by the viewers of the videos. The emotional information was automatically extracted with an automatic sentiment detection tool whose reliability was tested with human coders. Ordinary least squares regression models were used to estimate the strength of sentiments. The models controlled for the number of video views and comments, number of months the video had been on YouTube, duration of the video, uploader's activity as a video commentator, and uploader's physical location by country. RESULTS: The 395 videos had more than 6 million views and comments by almost 8000 users. Anti-pro-anorexia video comments expressed more positive sentiments on a scale of 1 to 5 (adjusted prediction [AP] 2.15, 95% CI 2.11-2.19) than did those of pro-anorexia videos (AP 2.02, 95% CI 1.98-2.06). Anti-pro-anorexia videos also received more likes (AP 181.02, 95% CI 155.19-206.85) than pro-anorexia videos (AP 31.22, 95% CI 31.22-37.81). Negative sentiments and video dislikes were equally distributed in responses to both pro-anorexia and anti-pro-anorexia videos. CONCLUSIONS: Despite pro-anorexia content being widespread on YouTube, videos promoting help for anorexia and opposing the pro-anorexia community were more popular, gaining more positive feedback and comments than pro-anorexia videos. Thus, the anti-pro-anorexia content provided a user-generated counterforce against pro-anorexia content on YouTube. Professionals working with young people should be aware of the social media dynamics and versatility of user-generated eating disorder content online.

Bilingualism and performance on two widely used developmental neuropsychological test batteries.

The present study investigated the effect of bilingualism on the two widely used developmental neuropsychological test batteries Wechsler Intelligence Scale for Children - Fourth Edition (WISC-IV) and A Developmental Neuropsychological Assessment, Second Edition (NEPSY-II) in children. The sample consisted of 100 Finland-Swedish children in two age groups. About half (n = 52) of the participants were early simultaneous bilinguals, and the other half (n = 48) were monolinguals. As no Finland-Swedish versions of the tests are available at the moment, both tests were translated and adapted to suit this population. The results revealed no difference in the performance between bilingual and monolingual children. This speaks against a cognitive advantage in bilingual children and indicates that development of separate norms for monolingual and bilingual children is not needed for clinical use.
