Magnetic resonance is a powerful technology that has had a major impact across the physical, life, and medical sciences, from chemistry to medical imaging, with ever-expanding applications in new areas as diverse as mining and food science. It is, however, also a difficult subject to teach, as the theory is complex and requires some familiarity…

In the past decade, American and Canadian pediatric societies have recommended that pediatric care clinicians follow a schedule of routine surveillance and screening for young children to detect conditions such as developmental delay, speech and language delays and disorders, and autism spectrum disorder. The goal of these recommendations is to…

Purpose: Children with specific language impairment (SLI) demonstrate significant language impairments despite normal-range hearing and nonverbal IQ. Many of these children also show marked deficits in working memory (WM) abilities. However, the theoretical and clinical characterization of the association between WM and language limitations in SLI…

Over the past two decades, several two-tier multiple-choice diagnostic tests in science at a variety grade levels have been reported in the extant literature from several countries. This review summarises these studies, provides an overview of the methodology for their construction, presents two examples of typical items, and lists studies…

Patterns of sensory abnormalities in children and adults with autism were examined using the Diagnostic Interview for Social and Communication Disorders (DISCO). This interview elicits detailed information about responsiveness to a wide range of sensory stimuli. Study 1 showed that over 90% of children with autism had sensory abnormalities and had…

The repeated psychological assessment of 41 high-risk infants during the first 2 years of life using the Mental Scale of the Bayley Scales of Infant Development was investigated. Analyses indicated that the infants' cognitive functioning remained fairly stable over the 2 years, particularly from age 6 months on. (Author/JDD)

This paper examines how clumsiness has been defined and assessed in the literature on Asperger syndrome. Of 42 identified papers, 23 mentioned clumsiness as a feature of the syndrome and 4 stated that they had used tests specifically to assess clumsiness, but none of the publications defined clumsiness. (JDD)

This study established a normal middle ear resonance estimated from sweep frequency tympanometry, established normal equivalent ear canal volume, static acoustic admittance, and tympanometric peak pressure at 226 hertz in 90 children with normal hearing and 68 children with deafness, ages 6-15. No significant intergroup or age differences were…

The Khan-Lewis Phonological Analysis (KLPA) documents and analyzes phonological process usage in children. This review examines the KLPA's 15 phonological processes and its normative data. The review concludes that the KLPA remains a user-friendly and time-efficient method of phonological analysis, though somewhat limited in analyzing speech…

The performance of 17 prelingually severely and profoundly hearing-impaired subjects on the Speech Pattern Contrast Test (Version II) was evaluated. Although performance on most of the contrast subtests was significantly correlated with phoneme and word recognition, intercorrelations among most subtests were also significant. (Author/DB)

Actual and theoretical cases are presented in which the Battelle Developmental Inventory was used in infant assessment. Age-related discontinuities reveal that, for children whose chronological age abuts one of the cut-off points between age categories, radically different summary scores can be obtained from one day to the next despite identical…

The Autism Diagnostic Observation Schedule, a standardized protocol for observation of social and communicative behavior associated with autism, is described. Data on interrater reliability as well as test-retest reliability and discriminant validity are provided. (Author/DB)

This paper reviewed the psychometric properties of the DSM-III-R (Diagnostic and Statistical Manual III, Revised) criteria for autism. Results indicated that the criteria had, on average, very good sensitivity but much lower specificity. It is concluded that the DSM-III-R criteria act more like screening criteria than diagnostic criteria.…

This article describes a nonstandardized method used to assess the degree to which school-aged children with communication disorders are competent with the pragmatic skill of referential communication. Results with six children (ages 8-12) with communication disorders revealed that subjects possessed at least some referential communication…

Evaluation of 252 children with specific language impairments found varying degrees of congruence between clinically identified children and those identified using discrepancy, deficit, and standardized operational criteria. Results suggest that the global concept of a "specific language impairment" may not be a useful concept for either…
