The current study aimed to provide a comprehensive analysis of linguopalatal contact patterns in participants with acquired apraxia of speech (AOS). Tongue-to-palate contacts were recorded for three participants with AOS during consonant singletons and consonant clusters using the Reading Electropalatograph (EPG3) system. Amount and pattern of…

Children with unintelligible speech differ in severity, underlying deficit, type of surface error patterns and response to treatment. Detailed treatment case studies, evaluating specific intervention protocols for particular diagnostic groups, can identify best practice for children with speech disorder. Three treatment case studies evaluated the…

Thai has its own distinctive alphabetic script with syllabic characteristics as it has implicit vowels for some consonants. Consonants are written in a linear order, but vowels can be written non-linearly above, below or to either side of the consonant. Of particular interest to the current study are that vowels can precede the consonant in…

Sales figures and recollections of psychologists indicate textbooks play a central role in psychology students' education, yet instructors typically must select texts under time pressure and with incomplete information. Although selection aids are available, none adequately address the accuracy of texts. We describe a technique for sampling…

Existing research indicates that instructed learners' L2 proficiency and their metalinguistic knowledge are moderately correlated. However, the operationalization of the construct of metalinguistic knowledge has varied somewhat across studies. Metalinguistic knowledge has typically been operationalized as learners' ability to correct, describe,…

Semantic errors are commonly found in semantic dementia (SD) and some forms of stroke aphasia and provide insights into semantic processing and speech production. Low error rates are found in standard picture naming tasks in normal controls. In order to increase error rates and thus provide an experimental model of aphasic performance, this study…

J. S. Adelman and G. D. A. Brown (2008) provided an extensive analysis of the form of word frequency and contextual diversity effects on lexical decision time. In this reply, the current authors suggest that their analysis provides a valuable tool for the evaluation of models of lexical access and that the results they report are broadly…

This article describes the use of African American English (AAE) in the written and oral language of African American adolescents who struggle with writing. Written and oral language samples of 22 African American 10th-grade students were transcribed, analyzed, and coded for AAE, grammatical errors, spelling errors, and punctuation errors. Four…

Learning about letters is an important foundation for literacy development. Should children be taught to label letters by conventional names, such as /bi/ for "b", or by sounds, such as /b[inverted e]/? We queried parents and teachers, finding that those in the United States stress letter names with young children, whereas those in…

This investigation examined the effects of Classwide Peer Tutoring (CWPT), a variation of peer tutoring on the volleyball skills of four 6th grade middle school students purposefully selected from an intact class of 21 students. Participants were average to low skilled males and females. A single subject A-B-A-B withdrawal design was used to…

The interpretation of cognitive test scores often leads to decisions concerning the diagnosis, educational placement, and types of interventions used for children. Therefore, it is important that practitioners administer and score cognitive tests without error. This study assesses the frequency and types of examiner errors that occur during the…

In this study, we focus on particle errors and discuss an annotation scheme for Korean learner corpora that can be used to extract heuristic patterns of particle errors efficiently. We investigate different properties of particle errors so that they can be later used to identify learner errors automatically, and we provide resourceful annotation…

Background: Previous studies, both in hospitals and in institutions for clients with an intellectual disability (ID), have shown that medication errors at the administration stage are frequent, especially when medication has to be administered through an enteral feeding tube. In hospitals a specially designed intervention programme has proven to…

This study compared the effects of static photographs and video prompts on the independent performance of cooking related tasks by six young adults with moderate intellectual disabilities. An adapted alternating treatment design with baseline and final treatment phase was used to measure the percentage of tasks correctly completed by each student…

Second language (L2) learners notoriously have trouble using articles in their target languages (e.g., "a", "an", "the" in English). However, researchers disagree about the patterns and causes of these errors. Past studies have found that L2 English learners: (1) Predominantly omit articles (White 2003, Robertson 2000), (2) Overuse "the" (Huebner…
