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…

Neighborhood size and neighborhood frequency were orthogonally varied in two experiments on Italian nonwords. In Experiment 1, an inhibitory effect of neighborhood frequency on visual lexical decision was found: The presence of one high-frequency neighbor increased response latencies and error rates to nonwords. By contrast, no effect of…

This study addresses an issue of global concern in skills training, namely, the rapid and permanent eradication of persistent habit errors, and bad or unsafe working practices. This article offers an alternative human factors explanation for the profound difficulties and low transfer of training experienced during error pattern retraining, and the…

We tested the effects of writer immersion and the responses emitted by a peer reader across four male middle school participants diagnosed with behavioral disorders. The participants were chosen for this study due to their high structural errors and inability to write functionally in order to affect the behavior of a reader. Writer immersion and…

This study investigated the effects of the Direct Instruction writing program, "Expressive Writing" (Engelmann & Silbert, 1983), for high school students with learning disabilities (LD). The study used a multiple probe design across participants and results indicate the effectiveness of "Expressive Writing" in improving the writing skills of high…

An analysis of the 1990 National Assessment of Educational Progress (NAEP) found that only 46 percent of all high school seniors demonstrated success with a grasp of decimals, percentages, fractions and simple algebra. This article investigates error patterns that emerge as students attempt to answer questions involving the ability to apply…

Conjunction errors occur when participants incorrectly identify as "old" novel test stimuli created by recombining parts of two study stimuli (parent items). Prior studies have reported that the conjunction error rate is higher when parent items are studied together than when they are studied apart (a parent proximity effect). In several…

There has been little or no research on Vietnamese phonological development, let alone on phonological disorders of Vietnamese-speaking children. The goal of this study is to evaluate the sound systems of monolingual Vietnamese-speaking children with phonological impairment. Independent and relational analyses of four children (ages 4;4 to 5;5)…

This study investigated the role of concurrent musical parts in pitching ability in sight-singing, concentrating on the effects of melodic and harmonic coherence. Twenty-two experienced singers sang their part twice in each of four novel chorales. The chorales contained either original or altered melody and original (tonal) or altered (atonal)…

A review of the help files in several major databases revealed that database vendors have begun including information on citing sources, which has the potential to be very useful to students. Surprisingly, 94% of the citation examples in the databases reviewed had errors. The average number of errors per example was 4.3. The citation help appears…
