The current investigation explored the diagnostic utility of reading fluency measures in the identification of children with
reading disabilities. Participants were 50 children referred to a university-based clinic because of suspected reading problems
and/or a prior diagnosis of dyslexia, where children completed a battery of standardized intellectual, reading achievement,
and processing measures. Within this clinical sample, a group of children were identified that exhibited specific deficits
in their reading fluency skills with concurrent deficits in rapid naming speed and reading comprehension. This group of children
would not have been identified as having a reading disability according to assessment of single word reading skills alone,
suggesting that it is essential to assess reading fluency in addition to word reading because failure to do so may result
in the under-identification of children with reading disabilities. 相似文献

Eco‐webbing is a teaching strategy that can be used to help counselor educators integrate a social justice focus into their courses. Preliminary data indicated increased critical consciousness and social justice agency as a result of using eco‐webbing with counseling students (N = 17). The authors provide implications for counselor educators and future research. 相似文献

Rats were trained on reinforcement schedules which generated high or low response rates. After extinguishing responding by eliminating food-reinforcement delivery, response-independent food presentations reinstated responding. Higher response rates occurred if the schedule preceding extinction controlled high response rates, suggesting that discriminative stimulus properties of the reinforcer were a function of antecedent training schedules. 相似文献

In a category-learning experiment, we assessed whether participants were able to selectively attend to different components of a compound stimulus in two distinct contexts. The participants were presented with stimulus compounds for which they had to learn categorical labels. Each compound comprised one feature from each of two dimensions, and on different trials the compound was presented in two contexts, X and Y. In Context X, Dimension A was relevant to the solution of the categorization task and Dimension B was irrelevant, whereas in Context Y, Dimension A was irrelevant and Dimension B was relevant. The results of transfer tests to novel stimuli suggested that people learned to attend selectively to Dimension A in Context X and Dimension B in Context Y. These findings contribute to the growing body of evidence that people can learn to selectively attend to particular dimensions of stimuli dependent on the context in which the stimuli are presented. Furthermore, the findings demonstrate that context-dependent changes in attention transfer to other categorization tasks involving novel stimuli. 相似文献

Recent discussions of practices in higher education have tended toward muck-raking and self-styled exposure of cynical self-indulgence by faculty and administrators at the expense of students and their families, as usually occurs during periods of economic duress, rather than toward analytical studies designed to foster understanding This article looks briefly at some examples of this tendency and then offers an analytical approach to understanding faculty workloads and the ways of assessing and evaluating faculty work. 相似文献

The states of radiation of a single frequency and polarization propagating in free space are very conveniently represented
by those of a quantum mechanical simple harmonic oscillator. This fact is exploited, together with the Ehrenfest theorem,
to map the time evolution of the radiation to the dynamics of the oscillator. This enables a graphical comparison of the behaviour
of classical and nonclassical states of radiation. 相似文献

Abstract The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO2max) based on nonexercise (N-EX) data. All participants (N= 100), ages 18–65 years, successfully completed a maximal graded exercise test (GXT) to assess VO2max (M= 39.96 mL·kg -1· min -1 , SD = 9.54). The N-EX data collected just before the maximal GXT included the participant's age; gender; body mass index (BMI); perceived functional ability (PFA) to walk, jog, or run given distances; and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 mL·kg -1· min -1 , %SEE= 8.62): VO2max (mL·kg -1· min -1 ) = 48.0730 + (6.1779 x gender; women = 0, men = 1) – (0.2463 x age) – (0.6186 x BMI) + (0.7115 x PFA) + (0.6709 x PA-R). Cross validation using PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage (R p = .91 and SEE p = 3.63 mL·kg -1· min -1 ); thus, this model should yield acceptable accuracy when applied to an independent sample of adults (ages 18–-65 years) with a similar cardiorespiratory fitness level. Based on standardized β-weights, the PFA variable (0.41) was the most effective at predicting VO2max followed by age (-0.34), gender (0.33), BMI (-0.27), and PA-R (0.16). This study provides a N-EX regression model that yields relatively accurate results and is a convenient way to predict VO2max in adult men and women. 相似文献

Abstract Hearts from 126 male Sprague-Dawley rats (two age groups) were studied to determine effects of age, chronic hypoxia, and exercise on ventricular weight. Exercised rats had significantly heavier absolute total ventricular weights (right plus left) compared with chronically hypoxic or control rats. Whether expressed as absolute or percent total ventricular weight, chronically hypoxic rats had significantly larger right ventricles but significantly smaller left ventricles than exercised or control rats. Expressed as absolute weight, older rats (11 months) had significantly larger right or left ventricles than young rats (3 months). Expressed as percent total ventricular weight, young rats had left ventricles 4% smaller, but right ventricles 4% larger than older rats (p <.05). Type of work overload (volume or pressure) and functional location of workload (pulmonary or systemic) were suggested physiological mechanisms for stress- and age-related changes in myocardial mass. 相似文献
