Connecting inside out: Development of the social brain in infants and toddlers with a focus on myelination as a marker of brain maturation     

Nora Schneider  Elizabeth Greenstreet  Sean C. L. Deoni 《Child development》2022,93(2):359-371

Early childhood is a sensitive period for learning and social skill development. The maturation of cerebral regions underlying social processing lays the foundation for later social-emotional competence. This study explored myelin changes in social brain regions and their association with changes in parent-rated social-emotional development in a cohort of 129 children (64 females, 0–36 months, 77 White). Results reveal a steep increase in myelination throughout the social brain in the first 3 years of life that is significantly associated with social-emotional development scores. These findings add knowledge to the emerging picture of social brain development by describing neural underpinnings of human social behavior. They can contribute to identifying age-/stage-appropriate early life factors in this developmental domain.  相似文献

Research Training Needs of Scientist‐Practitioners: Implications for Counselor Education          下载免费PDF全文

Christina Hamme Peterson  Sean B. Hall  Juleen K. Buser 《Counselor Education & Supervision》2016,55(2):80-94

Counselors (N = 911) reported the research skills needed for practice and subsequent research training needs. Findings indicate that counselors have a high need for research skills at work, but training needs differ significantly by counselor type. Recommendations include increasing emphasis on single‐case design, survey design, and widely available data analysis tools.  相似文献

Effect of the look-up line on the gaze and head orientation of elite ice hockey players

Abstract

A “look-up line” (LUL) has been proposed for ice hockey, which is an orange 1?m (40′) warning line (WL) painted on the ice at the base of the boards. The LUL purports to provide an early warning to players to keep their head up prior to and as they are being checked. We determined if players looked up more on a rink with the LUL compared to a traditional Control rink. Elite offensive (O) and defensive (D) players competed 1 vs. 1, while wearing an eye tracker that recorded their quiet eye (QE) and fixation and tracking (F-T) and an electrogoniometer that measured head angle. External cameras recorded skate duration during four skate phases: P1 preparation, P2 decision-making, P3 cut to boards, P4 contact. The QE was the final fixation prior to contact between O and D as they skated towards and across the WL during P3 and P4. Skate phase durations (%) did not differ by rink or rink by position. More QE and F-T occurred on the WL on the LUL rink than on the Control. The expected increase in head angle on the LUL rink did not occur during P3 or P4. Post-hoc results also showed O and D skated further from the boards on the LUL rink, suggesting the players preferred to control the puck on white ice, rather than the orange colour of the LUL rink. More research is needed to determine if these results apply to the competitive setting.  相似文献

A comparison of methods to determine bilateral asymmetries in vertical leg stiffness     

Sean J. Maloney  Iain M. Fletcher  Joanna Richards 《Journal of sports sciences》2016,34(9):829-835

Whilst the measurement and quantification of vertical leg stiffness (K_vert) asymmetry is of important practical relevance to athletic performance, literature investigating bilateral asymmetry in K_vert is limited. Moreover, how the type of task used to assess K_vert may affect the expression of asymmetry has not been properly determined. Twelve healthy males performed three types of performance tasks on a dual force plate system to determine K_vert asymmetries; the tasks were (a) bilateral hopping, (b) bilateral drop jumping and (c) unilateral drop jumping. Across all the three methods, K_vert was significantly different between compliant and stiff limbs (P < 0.001) with a significant interaction effect between limb and method (P = 0.005). Differences in K_vert between compliant and stiff limbs were ?5.3% (P < 0.001), ?21.8% (P = 0.007) and ?15.1% (P < 0.001) for the bilateral hopping, bilateral drop jumping and unilateral drop jumping methods, respectively. All the three methods were able to detect significant differences between compliant and stiff limbs, and could be used as a diagnostic tool to assess K_vert asymmetry. Drop jumping tasks detected larger K_vert asymmetries than hopping, suggesting that asymmetries may be expressed to a greater extent in acyclic, maximal performance tasks.  相似文献   

A moral basis for prohibiting performance enhancing drug use in competitive sport     

Sean McKeever 《体育哲学杂志》2017,44(2):243-257

A strong moral reason for prohibiting doping in sport is to be found in the bad choices that would be faced by clean athletes in a sporting world that tolerated doping. The case against doping is not, however, to be grounded in the concept of coercion. Instead, it is grounded in a general duty of sport to afford fair opportunity to the goods that are distinctively within sport's sphere of control. The moral reason to prohibit doping need not be balanced against any autonomy claim of athletes who would prefer to dope because, upon closer examination, such claims have no force. The moral reason to prohibit doping does, however, need to be balanced against the enforcement costs imposed on all athletes by effective prohibition.  相似文献   

Heredity, reproduction, and perfectibility in revolutionary and Napoleonic France, 1789-1815     

Quinlan S 《Endeavour》2010,34(4):142-150

During the French Revolution, there appeared a striking and far-ranging medical literature on heredity, reproduction and biological 'perfectibility'. In some ways anticipating ideas associated with modern eugenics, these writings emerged from radical revolutionary projects for 'physical and moral regeneration' and incarnated deep-seated desires to transform French society and make a 'new man' in mind and body. But by breaking down boundaries between public and private life, doctors did more than just try to regulate intimate sexual behaviour. Instead, they proffered a more intimate vision of civic volunteerism, in which sexual hygiene and domestic practices allowed their patients to imagine new forms of society and gave them ways to attain these socio-political dreams. Moreover, they were responding to powerful new worries about heredity and sought to counsel their patients in the ways of family panning. By the end of revolutionary period, then, medical and lay thinkers had transformed the marriage bed and household into a specially controlled environment - a kind of affective laboratory - in which conscientious parents could make healthy children and raise them in the context of specific political and social values.  相似文献
