Early reading and spelling development share foundational skills, yet spelling assessment is underutilized in evaluating early reading. This study extended research comparing the degree to which methods for scoring spelling skills at the end of kindergarten were associated with reading skills measured at the same time as well as at the end of first grade. Five strategies for scoring spelling responses were compared: totaling the number of words spelled correctly, totaling the number of correct letter sounds, totaling the number of correct letter sequences, using a rubric for scoring invented spellings, and calculating the Spelling Sensitivity Score (Masterson & Apel, 2010b). Students (N = 287) who were identified at kindergarten entry as at risk for reading difficulty and who had received supplemental reading intervention were administered a standardized spelling assessment in the spring of kindergarten, and measures of phonological awareness, decoding, word recognition, and reading fluency were administered concurrently and at the end of first grade. The five spelling scoring metrics were similar in their strong relations with factors summarizing reading subskills (phonological awareness, decoding, and word reading) on a concurrent basis. Furthermore, when predicting first-grade reading skills based on spring-of-kindergarten performance, spelling scores from all five metrics explained unique variance over the autoregressive effects of kindergarten word identification. The practical advantages of using a brief spelling assessment for early reading evaluation and the relative tradeoffs of each scoring metric are discussed. 相似文献

Little is known about the relationship between diurnal cortisol secretion patterns and cognitive function early in life. This population-based study examined whether diurnal cortisol rhythms and cognitive functioning in toddlers are related. Within the Generation R Study, parents of 364 infants (median age: 14.2 months) collected saliva samples at five moments during one day. We assessed the diurnal cortisol rhythm by calculating the area under the curve (AUC), the cortisol awakening response (CAR), and the diurnal slope. Verbal cognitive functioning and fine motor development was determined at age 18 months. Nonverbal cognitive functioning was assessed at age 30 months. A more positive CAR was associated with a lower risk of delay in language comprehension (OR per 1-SD CAR: 0.62, 95%CI: 0.40–0.98, p = .04), a lower risk of nonoptimal fine motor development (OR per 1-SD slope: 0.74, 95%CI: 0.57–0.96, p = .03), and a lower risk of delay in nonverbal cognitive development (OR per 1-SD CAR: 0.58, 95%CI: 0.38–0.90, p = .02). Also, children with flatter slopes had a lower risk of delay in nonverbal cognitive development (OR per 1-SD slope: 0.51, 95%CI: 0.34–0.76, p = .001). Higher AUC levels were associated with a higher risk of delay in language production. These results show that variations in diurnal cortisol rhythms are already associated with variations in cognitive functioning at a young age. Infants with a diurnal cortisol pattern indicative of less stress and more cortisol reactivity, that is, lower AUC levels and a more positive CAR, show a lower risk of delay in cognitive functioning as toddlers. 相似文献

Intermetallic γ-TiAl sheet material of composition Ti–46?at.%Al–9?at.%Nb and two different microstructures (fine-grained near-gamma and coarse-grained fully lamellar) was studied by mechanical-loss (internal-friction) measurements using two frequency ranges: (I) 0.01–10?Hz and (II) around 2?kHz. The mechanical spectra in range I show (i) a loss peak of Debye type at T?≈?1000?K, which occurs only in fully lamellar samples; and (ii) a high-temperature damping background above?≈?1100?K. The values of the activation enthalpy H of the high-temperature background, 4.3?eV (near-gamma) and 4.2?eV (fully lamellar), which were determined from the frequency shift, are distinctly higher than those obtained for TiAl sheet material with low Nb content. The high-temperature damping background is assigned to diffusion-assisted climb of dislocations, and the 1000?K peak (H?=?2.9?eV) to local (reversible) glide of dislocation segments anchored between lamella interfaces. From measurements of the eigenfrequency in range II, the variation of Young's modulus in the temperature range 300–1000?K was determined. 相似文献

The authors examined the validity of an Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) for assessing individual differences in achievement tendencies. Eighty-eight students completed an IAT and explicit self-ratings of achievement orientation, and were then administered a mental concentration test that they performed either in the presence or in the absence of achievement-related feedback. Implicit and explicit measures of achievement orientation were uncorrelated. Under feedback, the IAT uniquely predicted students’ test performance but failed to predict their self-reported task enjoyment. Conversely, explicit self-ratings were unrelated to test performance but uniquely related to subjective accounts of task enjoyment. Without feedback, individual differences in both performance and enjoyment were independent of differences in either of the two achievement orientation measures. 相似文献

Cultural norms of behaviour influence desirable and problematic behaviours of individuals. In particular, cultural norms should influence individuals' dishonesty. In a recent Nature study, prevalence of rule violations was introduced as a new country‐level measure of behavioural norms. However, information on individuals' actual honesty was not available due to characteristics of the experimental design. Overcoming this limitation, we show that country‐level behavioural norms are related to individual‐level knowledge overclaiming behaviour (i.e., claiming to know concepts that do not exist, a measure of individuals' actual behavioural dishonesty) among 290,954 students from 57 countries (from the 2012 PISA study). Our study represents a crucial test of the argument that cultural norms influence individual's behaviour and of the validity of the measurement of countries' prevalences of rule violations. These results imply that shaping the behaviour of today's students may result in new behavioural norms that emphasise honesty and rule adherence more strongly. 相似文献

The social self-preservation theory states that humans have a fundamental motivation to preserve the social self and that threats to the social self perturb biological markers such as cortisol. Five studies were designed to examine the cortisol response to competitive ballroom dancing as a paradigm for real-life social-evaluative threat. Competitive dancing produced substantial increases in cortisol compared to a control day. These increases were not due to the physical strain of dancing and were greater than those found during social-evaluative laboratory stressors. Responses did not habituate across competitions and were mostly elevated under highly focused conditions of threat (couple vs. group competition). These findings support the notion of a social self-preservation system that is physiologically responsive to threats to the social self. 相似文献
