冬奥会奖牌得主有哪些“后路”

第二十一届冬季奥林匹克运动会在今年年初就落下了帷幕,但是这届盛会还是给全世界人民留下了深刻的印象,尤其是冰雪赛场上运动员们的精彩表现更是让观众惊叹不已。透过这些或舒展优美、或惊险刺激的表演,让我们走进历届冬奥会奖牌获得者的生活,了解他们在日常生活中不为人知的一面。虽然有些奖牌获得者已经选择退出他们为之奋斗的体育事业,但退役后的他们依然在各个领域继续发光发热,呈现不一样的精彩。     

Groupitizing reflects conceptual developments in math cognition and inequities in math achievement from childhood through adolescence

Understanding the cognitive processes central to mathematical development is crucial to addressing systemic inequities in math achievement. We investigate the “Groupitizing” ability in 1209 third to eighth graders (mean age at first timepoint = 10.48, 586 girls, 39.16% Asian, 28.88% Hispanic/Latino, 18.51% White), a process that captures the ability to use grouping cues to access the exact value of a set. Groupitizing improves each year from late childhood to early adolescence (d = 3.29), is a central predictor of math achievement (beta weight = .30), is linked to conceptual processes in mathematics (minimum d = 0.69), and helps explain the dynamic between the ongoing development of non-symbolic number concepts, systemic educational inequities in school associated with SES, and mathematics achievement (minimum beta weight = .11) in ways that explicit symbolic measures may miss.     

The effects of frequency of encouragement on performance during maximal exercise testing

The aim of this study was to determine the effects of frequency of verbal encouragement during maximal exercise testing. Twenty-eight participants (12 males, 16 females) aged 20.9 - 1.5 years (mean - s ) performed a maximal exercise test ( V O 2max ) on a treadmill without any verbal encouragement. The participants were matched according to their pre-test V O 2max and placed into either a control group or one of three experimental groups. They performed a second exercise test (post-test) 1 week later. During the second test, the control group received no verbal encouragement; the 20 s (20E), 60 s (60E) and 180 s (180E) encouragement groups received verbal encouragement every 20, 60 and 180 s, respectively, beginning with stage 3 of the exercise test. Relative V O 2max , exercise time, blood lactate concentration, respiratory exchange ratio (RER) and ratings of perceived exertion (RPE) were not significantly different from the first test to the second test for the control group without verbal encouragement and the 180E group that received infrequent encouragement. Post-test values were significantly higher than pre-test values for the 20E and 60E groups. The post-test values of the 20E group were significantly higher than their pre-test values for relative V O 2max ( P ? 0.001), exercise time ( P ? 0.0001), blood lactate concentr . ation ( P ? 0.05), RER ( P ? 0.01) and RPE ( P ? 0.0001); this was also the case for the 60E group for relative V O 2max ( P ? 0.01), blood lactate concentration ( P ? 0.05), RER ( P ? 0.05) and RPE ( P ? 0.05). The results suggest that frequent verbal encouragement (every 20 s and 60 s in the present study) leads to significantly greater maximum effort in a treadmill test than when no encouragement is given or when the encouragement is infrequent (i.e. every 180 s).     

Theory of mind and language in children with cochlear implants

Thirty children with cochlear implants (CI children), age range 3-12 years, and 30 children with normal hearing (NH children), age range 4-6 years, were tested on theory of mind and language measures. The CI children showed little to no delay on either theory of mind, relative to the NH children, or spoken language, relative to hearing norms. The CI children showed a slightly atypical sequence of acquisition of theory of mind concepts. The CI children's theory of mind performance was associated with general syntactic proficiency more than measures of complement syntax, and with time since implantation more than age at implantation. Results suggest that cochlear implantation can benefit spoken language ability, which may then benefit theory of mind, perhaps by increasing access to mental state language.     

Mindfulness Interventions for College Students with ADHD: A Multiple Single Case Research Design

A multiple single case research design (SCRD) was used to examine two mindfulness interventions (MBSR and Vipassana meditation). Impacted symptoms of Attention Deficit Hyperactivity Disorder (ADHD), psychological distress, mindfulness, and treatment satisfaction in college students were examined via single subject and group analyses. Results indicated that 57% of the seven-person sample evidenced decreases in ADHD symptoms, 72% decreased in distress, 72% increased on the trait measure of mindfulness, and treatment satisfaction was high. Clinical implications and future directions are discussed.     

Clinical Anatomy and Unexpected Careers: Is There Curriculum for That?

Reduction in faculty positions in higher education and increased graduate matriculation rates represent a higher education conundrum. Planned happenstance theory (PHT) is a career development model focusing on positive outcomes resulting from unpredictable precareer events. This mixed methods study explores how PHT applies to the career paths of a clinical anatomy (CA) postgraduate cohort. It provides insight into educational practices designed to equip students for labor markets inside and outside academia. Alumni of CA (n = 12; 2014-2018) were interviewed about career-related events transpiring from graduate studies to present, allowing exploration on how PHT contextualizes their shared experiences. Planned happenstance career inventory (PHCI) enumerated planned happenstance skill (PHS) scores. Total PHS was referenced 527 times across 12 interviews. Of the PHS references, curiosity established highest incidence (154 references, 29%), optimism (132 references, 25%), flexibility (101 references, 19%), risk-taking (85 references, 16%), and persistence (55 references, 10%) and 43 distinct happenstance events were documented. In addition, social networking (52 references) arose as an emergent code and was divided into internal networking (28 references, 54%) and external networking (24 references, 46%). Application of the five-point PHCI scale revealed: curiosity (4.4 ± 0.3; mean ± SD), flexibility (3.6 ± 0.7), persistence (4.4 ± 0.3), optimism (4.3 ± 0.4), and risk-taking (4.1 ± 0.5). Curiosity had the strongest association with happenstance event incidence. Social networking was a key substituent of PHT not yet described in the literature. Educational practices incorporating PHT concepts, with emphasis on curiosity, may provide graduates novel metacognitive skills needed to develop novel career paths.     

Spontaneous Self‐Distancing and Adaptive Self‐Reflection Across Adolescence

Experiments performed primarily with adults show that self‐distancing facilitates adaptive self‐reflection. However, no research has investigated whether adolescents spontaneously engage in this process or whether doing so is linked to adaptive outcomes. In this study, 226 African American adolescents, aged 11–20, reflected on an anger‐related interpersonal experience. As expected, spontaneous self‐distancing during reflection predicted lower levels of emotional reactivity by leading adolescents to reconstrue (rather than recount) their experience and blame their partner less. Moreover, the inverse relation between self‐distancing and emotional reactivity strengthened with age. These findings highlight the role that self‐distancing plays in fostering adaptive self‐reflection in adolescence, and begin to elucidate the role that development plays in enhancing the benefits of engaging in this process.
