Purpose: The aim of this study was to investigate the extent to which researchers in the field of developmental language disorder are utilizing validated methods to diagnose their research participants. Method: We examined 90 research articles published from 2015 to 2019 that included English-speaking participants from the United States who were…

Background: As new standardized tests become commercially available, it is critical that clinicians have access to the information about a test's psychometric properties, including aspects of reliability. Aims: The purpose of the three studies reported in this article was to investigate the reliability of a new test, the Test of Integrated…

Purpose: Adults with language-based disabilities are known to have deficits in oral language; however, less is known about their written language skills. Two studies were designed to characterize the writing of adults with language-based disabilities. Method: In Study 1, 60 adults, 30 with language impairment and 30 with typical language,…

The present study investigated a possible connection between speech processing and cochlear function. Twenty-two subjects with age range from 18 to 39, balanced for gender with normal hearing and without any known neurological condition, were tested with the dichotic listening (DL) test, in which listeners were asked to identify CV-syllables in a…

Purpose: In order to support evidence-based practice, this study served to evaluate the diagnostic accuracy, convergent validity, and divergent validity of the Structured Photographic Expressive Language Test-Preschool: Second Edition (SPELT-P2; J. Dawson, J. A. Eyer, J. Fonkalsrud, 2005) in order to determine whether it can be used as a valid…

Purpose: Two studies are presented providing evidence indicating the diagnostic and predictive validity of the American version of "The Renfrew Bus Story" (J. Cowley & C. Glasgow, 1994). Method: Thirty-two children with specific language impairment (SLI) and 32 children with typical language development participated in the first…

Prosodic information in the speech signal carries information about linguistic structure as well as emotional content. Although children are known to use prosodic information from infancy onward to assist linguistic decoding, the brain correlates of this skill in childhood have not yet been the subject of study. Brain activation associated with…

Purpose: This study examined the empirical evidence for using the Structured Photographic Expressive Language Test: Third Edition (SPELT-3; Dawson, Stout, & Eyer, 2003) to diagnose language impairment in preschool children. The SPELT-3 is a revision of the SPELT-II (Werner & Kresheck, 1983), which has been proven in the past to have high levels of…

Purpose: The assumption that children with language impairment will receive low scores on standardized tests, and therefore that low scores will accurately identify these children, is examined through a review of data in the manuals of tests that are intended for use in identifying such children. Method: Data from 43 commercially available tests…

How verbal information is processed and recalled appears to be influenced by the structure of the information presented (e.g., unrelated sentences vs. narratives) and the processes the listener uses to encode the information (e.g., verbatim encoding vs. gist extraction). Twenty adults, half with a history of learning disabilities (HLD) and half…

A study of 20 preschool children with specific language impairments and 20 typical preschool children examined the extent to which norm-referenced tests can identify a language impairment and determine specific areas of deficit. Results indicate the norm-referenced tests gave high discriminate capacity but inconsistent item-level performance.…
