Recent research has acknowledged the importance of morphological awareness, beyond phonological awareness, to literacy achievement in both reading and writing for children, adolescents, and adults. Morphological awareness is the ability to recognize, reflect on, and manipulate the sublexical structure of words--the roots, prefixes, and suffixes.…

Recent work has demonstrated the importance of derivational morphology to later language development and has led to a consensus that derivation is a lexical process. In this review, derivational morphology is discussed in terms of lexical representation models from both linguistic and psycholinguistic perspectives. Input characteristics, including…

In this article, we review three responses to the study and evaluation of grammar in children who speak nonmainstream dialects of English. Then we introduce a fourth, system-based response that views nonmainstream dialects of English, such as African American English (AAE) and Southern White English (SWE) as made up of "dialect-specific"…

Research findings concerning verb-level influences on past-tense morphology carry implications for the careful selection of treatment targets. Using 6 of the broad criteria for "good verbs to choose" proposed by D. Crystal (1985) more than 25 years ago as a framework, this article summarizes some of the more recent research with a nod…

Recently, it has been proposed that schools teach disciplinary literacy in science, mathematics, history, and literature classes as students move into middle school and high school. A disciplinary literacy approach emphasizes the specialized knowledge and abilities possessed by those who create, communicate, and use knowledge within each of the…

Disciplinary literacy is an increasingly popular focal area in adolescent literacy. In disciplinary literacy, the discourse features of specific knowledge domains (e.g., literature, history, science, and math) assume major importance in understanding and constructing meaning in each discipline. Because language plays a significant role in…

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that results in loss of most motor functions by the time of death. Most persons with ALS experience a dysarthria that eventually renders oral/vocal communication unintelligible. This article reviews the communication needs of persons with ALS and the range of communication…

Attention-deficit/hyperactivity disorder (ADHD) is a common developmental disorder often associated with other developmental disorders including speech, language, and reading disorders. Here, we review the principal features of ADHD and current diagnostic standards for the disorder. We outline the ADHD subtypes, which are based upon the dimensions…

Language impairment (LI) and attention-deficit/hyperactivity disorder (ADHD) are 2 relatively common developmental disorders that have been shown to have high rates of co-occurrence in a number of studies, and this phenomenon is also commonplace in the experience of many clinicians. Understanding this comorbidity, therefore, is central to building…

Dyslexia and attention-deficit/hyperactivity disorder (ADHD) are 2 of the most prevalent complex neurodevelopmental disorders of childhood, each affecting approximately 5% of the population in the United States. These disorders are also each comorbid with speech sound disorder and language impairment. Understanding the nature of the comorbidity…

Although emotions are often seen as key to maintaining rapport between speech-language pathologists and their clients, they are often neglected in the research and clinical literature. This neglect, it is argued here, comes in part from the inadequacies of prevailing conceptual frameworks used to govern practices. I aim to show how six such…

This article describes ways in which pragmatic language abilities may play a role in the writing performance of children and adolescents with language learning disabilities. First, a brief overview is presented of how pragmatic language difficulties might negatively influence writing performance. Next, research on the writing performance of…

Academic success depends heavily on students' ability to acquire information, but expository texts are difficult to process and comprehend, particularly for students with language difficulties. Support can be provided through instructional discourse, the interactive adult-student conversations that scaffold comprehension and content learning. This…

One of the primary purposes of expository text in education is to teach new content. Because elementary grade children are accustomed to applying their literacy skills to reading and writing narratives, they must be taught new skills if they are to access expository content effectively. These skills and practices can be challenging because…

In the past 12 years, middle and high school students across the United States have read with declining levels of proficiency compared to both international and national standards. It is thought that American students' overall low reading performance is related to the amount of expository material they must read with advancing grade levels. This…
