Genetic influences in different aspects of language development: the etiology of language skills in 4.5-year-old twins

The genetic and environmental etiologies of diverse aspects of language ability and disability, including articulation, phonology, grammar, vocabulary, and verbal memory, were investigated in a U.K. sample of 787 pairs of 4.5-year-old same-sex and opposite-sex twins. Moderate genetic influence was found for all aspects of language in the normal range. A similar pattern was found at the low end of the distribution with the exception of two receptive measures. Environmental influence was mainly due to nonshared factors, unique to the individual, with little influence from shared environment for most measures. Genetic and environmental influences on language ability and disability are quantitatively and qualitatively similar for males and females.     

How New Caledonian crows solve novel foraging problems and what it means for cumulative culture

New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question’s importance in understanding whether tool behavior is transmitted via social, genetic, or environmental means. For social transmission to account for tool-type variation, copying must utilize a mechanism that is action specific (e.g., pushing left vs. right) as well as context specific (e.g., pushing a particular object vs. any object). To determine whether crows can copy a demonstrator’s actions as well as the contexts in which they occur, we conducted a diffusion experiment using a novel foraging task. We used a nontool task to eliminate any confounds introduced by individual differences in their prior tool experience. Two groups had demonstrators (trained in isolation on different options of a four-option task, including a two-action option) and one group did not. We found that crows socially learn about context: After observers see a demonstrator interact with the task, they are more likely to interact with the same parts of the task. In contrast, observers did not copy the demonstrator’s specific actions. Our results suggest it is unlikely that observing tool-making behavior transmits tool types. We suggest it is possible that tool types are transmitted when crows copy the physical form of the tools they encounter.     

Personality of elite male and female chess players and its relation to chess skill

Whereas a lot of studies examine cognitive processes in chess players, personality profiles of elite chess players are still not described well. The aim of this study was to examine personality of strong chess experts and its influence on chess skill. We tested elite male and female chess players with Freiburg Personality Inventory Revised (FPI-R), which also provides population norms for males and females. Elite male players' personality profile did not significantly differ from the population norms. Female players were more satisfied with life, had less physical complaints and higher achievement motivation in comparison with female population norms. Personality was also related with chess skill but showed different patterns in males and females. Stronger male players were more introverted, while we found the opposite pattern in female players. These results indicate that personality plays an important role in the highest level of complex intellectual activities.     

Subject English as citizenship education

This article is equal parts educational history and political philosophy. We aim to remind readers that subject English (SE) and indeed state education emerge from the contradictory impulses of classical liberalism, and that, more than simply resembling citizenship education, SE emerges in the first instance as a form of highly normativising citizenship education. We further argue that, following England's recent educational reforms initiated by former Education Secretary Michael Gove, SE continues to be framed in moral terms consistent with citizenship education—again, of a highly normativising sort. England's current educational policy generally, and specifically the framing of SE, employs the language of liberal possibility, while ultimately espousing an invidious exclusionary and assimilationist politics. The framing of SE, moreover, is one that misrepresents the supposedly ‘rich and varied literary heritage’ it is supposed to exemplify and promote. The current political landscape in which the study of literature takes place is one where a crisis of liberalism is manifest (in terms of populism, radicalisation or apathy). However, we do not believe the answer is to retreat into a sealed, hermetic canon that excludes the reality that England and English literature are fundamentally multicultural and polyethnic. SE will be the poorer for not fully acknowledging and embodying this, for not enabling students to imaginatively and critically engage with characters and experiences that reflect both the present and long-standing diversity of English society, as well as its present and long-standing inequalities.     

Students’ Perspectives on LGBTQ-Inclusive Curriculum

Implementing curriculum that is inclusive of lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) people has the potential to create an equitable learning environment. In order to learn more about students’ experiences of LGBTQ-inclusive curriculum, 26 high school students with diverse racial/ethnic, sexual, and gender identities were recruited from the Gay Straight Alliance (GSA) Network in California. Students participated in focus groups conducted by telephone by GSA staff, sharing their experiences of LGBTQ-inclusive curriculum in school. Qualitative coding methods, including grounded theory, were used to identify themes and interpret students’ responses. Data revealed that LGBTQ-inclusive curriculum was most often taught in social sciences and humanities courses as stand-alone lessons. LGBTQ-inclusive curriculum rarely met standards of social justice education, though opportunities for critical conversations about systemic oppression regularly emerged. For instance, teachers often failed to intervene in LGBTQ bullying and missed teachable moments conducive to inclusive curriculum. Some students learned positive LGBTQ lessons and highlighted the ways such curriculum reflected their identities and created a supportive school climate. Implications for equitable education are discussed.     

Research on Social Integration: What Are The Problems?

THIS LIMITED REVIEW of research on the social integration of children with disabilities in mainstreaming programs showed that there are several factors which may explain the apparent inconsistencies within the research literature. The diverse groups of individuals involved necessitate that attention be paid to pertinent variables and that care must be taken when findings are generalized to other groups of children with disabilities. An issue of particular concern was the simplistic measuring techniques employed in some research, particularly where studies relied on a single technique such as sociometry. There is limited evidence to support the increased use of multivariate statistical procedures as a means of producing more consistent findings. While most studies reviewed did not incorporate special treatments, that is other than integrated settings, invariably such treatments produced positive outcomes. Studies involving research designs which used the social acceptance of normal children as the basis for assessing social integration frequently resulted in negative findings.     

Response Time Adjustment in the Stop Signal Task: Development in Children and Adolescents

Adjusting speed to maintain fast and accurate performance is critical to goal-directed behavior. This study examined development of response time adjustments in the stop signal task in 13,709 individuals aged 6–17 years (49.0% Caucasian) across four trial types: correct and incorrect go, successful (stop-inhibit), and failed (stop-respond) trials. People sped more after correct than incorrect go responses and slowed more after failed than successful stop trials. Greater slowing after stop-respond but less slowing after stop-inhibit trials was associated with better response inhibition. Response time adjustments were evident in children as young as age 6, developed throughout childhood, and plateaued by age 10. Results were consistent with the predictions of the error detection and shifting goal priority hypotheses for adjustments.     

White Paper: functionality and efficacy of wrist protectors in snowboarding—towards a harmonized international standard

The wrist is the most frequently injured body region among snowboarders. Studies have shown that the risk of sustaining a wrist injury can be reduced by wearing wrist protection. Currently, there are a wide variety of wrist protection products for snowboarding on the market that offer a range of protective features. However, there are no minimum performance standards for snowboarding wrist protectors worldwide. The International Society for Skiing Safety convened a task force to develop a White Paper to evaluate the importance and necessity of a minimum performance for all wrist protectors used in snowboarding. The White Paper outlines the need for a general framework for a harmonized international standard and reviews the existing evidence. Therefore, this White Paper may serve as a common base for future discussions. The broader goal of developing and implementing such a standard is to reduce the incidence and the severity of wrist injuries in snowboarding without increasing the risk of adverse events, such as upper arm or shoulder injury. The European standard for inline skating wrist protectors (EN 14120) can serve as a starting point for efforts related to a standard for snowboard wrist protectors, but certain modifications to the standard would be required. It is hypothesized that implementation of a snowboarding wrist protector standard would result in fewer and less severe wrist injuries in the sport and could translate into more riding days for healthy snowboarders and significant health-care costs savings.
