Compared 3- and 5-year olds' recall of a pediatric examination in verbal versus enactment interviews. Found that children in the enactment condition provided more spontaneous, elaborate reports than did children in verbal interview. Enactment produced increased errors by 3-year olds one week after examination, by both age groups after six weeks.…

Analyzes simulated performance ratings on a six-point scale by two independent raters to account for nonsystematic error in performance ratings. Results suggest that rater agreement or covariance is not always a dependable estimate of score reliability and that the practice of seeking additional raters for adjudication of discrepant ratings is not…

Identifies and discusses ten factors that contribute to the difficulties that language learners may have in dealing with false cognates. Provides suggestions for minimizing confusion. (Author/VWL)

Meta-analysis of the A-not-B error was conducted, using logistic regression, on studies conducted before September 1997. Results replicated earlier findings, with exception that the number of trials at the A location was a significant predictor, and the number of locations was a significant predictor of the proportion of infants who searched…

Background: Studies from the amnesia literature suggest that errorless learning can produce superior results to errorful learning. However, it was found in a previous investigation by the present authors that errorless and errorful therapy produced equivalent results for patients with aphasic word-finding difficulties. A study in the academic…

The standard Pearson correlation coefficient is a biased estimator of the true population correlation, ?, when the predictor and the criterion are range restricted. To correct the bias, the correlation corrected for range restriction, r-sub(c), has been recommended, and a standard formula based on asymptotic results for estimating its standard…

It is well-known that for normally distributed errors parametric tests are optimal statistically, but perhaps less well-known is that when normality does not hold, nonparametric tests frequently possess greater statistical power than parametric tests, while controlling Type I error rate. However, the use of nonparametric procedures has been…

Background: Although a number of studies have been conducted on normal acquisition in French, systematic methods for analysis of French and normative group data have been lacking. Aims: To develop a systematic method for the analysis of language samples in Quebec French, and to provide preliminary normative data on early lexical and syntactic…

We used the following multiple-choice question after a series of lectures in cardiovascular physiology in the first year of an undergraduate medical curriculum (n = 66) to assess whether students had understood the neural regulation of cardiovascular function. In health, neural cardiovascular mechanisms are geared toward maintaining A) cardiac…

Parallel versions of a new multiple-choice word-recognition test were administered to 1019 and 590 Year-1 pupils respectively. The test format was based on a published test of Word Recognition and Phonic Skills and was intended to provide reliable diagnostic information. It was found that internally consistent measures of three types of word…

Groups of first-grade (mean age = 82 months), third-grade (mean age = 107 months), and fifth-grade (mean age = 131 months) children with a learning disability in mathematics (MD, n=58) and their normally achieving peers (n = 91) were administered tasks that assessed their knowledge of counting principles, working memory, and the strategies used to…

Fifteen neurosurgical subjects, who were undergoing thalamic chronic electrode implants as a treatment for dyskinesia and chronic pain, were evaluated on a series of neurolinguistic functions to determine if the stimulation of the centromedianum nucleus of the thalamus affected language and cognitive processing. Analysis of the data revealed that…

Children aged 11-12 years with a diagnosis of dyslexia (DR) were compared to chronological and reading-age matched poor readers (PR), and two normal reader groups, age-matched (CA) and spelling and reading-age matched (SA-RA), on their processing of inflectional morphology. In comparison to SA-RAs and PRs, the DRs made more spelling errors on…

To deal with nonnormal and heterogeneous data for the one-way fixed effect analysis of variance model, the authors adopted a trimmed means method in conjunction with Hall's invertible transformation into a heteroscedastic test statistic (Alexander-Govern test or Welch test). The results of simulation experiments showed that the proposed technique…

Introduction: Stress in Spanish is associated with an orthographic mark that indicates stress, but there are also other clues that point to it. Most words have the same stress (on the penultimate syllable), and closed syllables (syllables ending in a consonant) attract the stress. In this paper we study these clues, and consequently the function…
