Clinicians can use the prevalence of low scores to help interpret test performance. However, this information is limited for most test batteries. In 2007, Crawford, Garthwaite, and Gault presented Monte Carlo simulation software for estimating the base rates of low scores for any battery of tests. The purpose of this study is to examine the accuracy of a Monte Carlo simulation program for estim...

This research examined two samples of students classified as learning disabled (LD) for evidence of the phenomenon known as the Flynn effect (FE; Flynn, 1999). Triennial test data were collected for two samples. Sample 1 included students tested twice with the Wechsler Intelligence Scale for Children—Third Edition (WISC-III; n 59). Sample 2, the primary data set, included students tested first ...

The Wechsler Intelligence Scale for Children--Third Edition (D. Wechsler, 1991; WISC-III) is often used to identify subtest-based cognitive strengths and weaknesses that are subsequently used to generate interventions. Given that intelligence is presumed to be an enduring trait, cognitive strengths and weaknesses identified via subtest analysis should also be stable over time. This was evaluate...

Top-down restoration mechanisms can enhance perception of degraded speech. Even in normal hearing, however, a large variability has been observed in how effectively individuals can benefit from these mechanisms. To investigate if this variability is partially caused by individuals' linguistic and cognitive skills, normal-hearing participants of varying ages were assessed for receptive vocabular...

PURPOSE Delayed treatment of congenital hypothyroidism (CH) is a common cause of mental retardation. The aim of the present study was to evaluate intellectual outcomes in preschool children with treated CH. METHODS We retrospectively reviewed the clinical records of 43 children (age range: 13 to 60 days of life; 22 girls and 21 boys) diagnosed with CH. Children aged 5 to 7 years were examined...
