The study involving 40 learning disabled children (6-8 years old) investigated the relationships between the various indexes of the McCarthy Scales of Children's Abilities (MSCA) and the scales of the Wechsler Intelligence Scale for Children-Revised (WISC-R), and the comparability between the MSCA General Cognitive Index and the WISC-R Full Scale…

In answer to R. Allington's criticism of the Jordan Left-Right Reversal Test (JLRRT), the author contends that Allington's research used an outdated version of the JLRRT, that Allington's research into the relationship of visual reversals to reading skills does not reflect on the validity of the test to measure reversals.

The concurrent validity of the Peabody Individual Achievement Test (PIAT) with 45 learning disabled children (7- to 12-years-old) was investigated using the California Achievement Test (CAT), the Wide Range Achievement Test (WRAT), and teacher ratings as criterion measures. (Author/DB)

To analyze differential diagnostic efficiency of the Revised Illinois Test of Psycholinguistic Abilities (a measure designed to assess strengths and weaknesses of learning disabled children), the Kelley procedure for estimating the proportion of differences in excess of chance was applied to the standardization data. (SBH)

Evaluated was whether factor analysis of the 12 Illinois Test of Psycholinguistic Abilities subtest scores earned by 90 underachieving children (between 5 and 10 years of age) would support the dimensions of psycholinguistic processes, organizational levels, and communication channels as described in the clinical model of the instrument.

The Visual Aural Digit Span Test (VADS Test), developed and standardized as a diagnostic test for learning disabilities in kindergarten to sixth grade, was adopted for use with seventh graders. An investigation of the relationship between the VADS Test scores and reading achievement showed the validity of the test for middle school pupils. (Author)

The study investigated the concurrent validity of the Peabody Individual Achievement Test (PIAT) with 60 learning disabled adolescents. Findings generally supported the concurrent validity of the PIAT as a measure of academic achievement with secondary learning disabled students. (SBH)

The Illinois Test of Pscyholinguistic Abilities was administered to 167 normal intelligence children (mean age 112 months) and then factor analyzed to determine construct validity and the extent to which each subtest measures a discrete combination of the psycholinguistic dimensions of level, process, and channel.

Investigated with 129 kindergarten children were test-retest reliability and validity of the Developmental Test of Visual Perception (DTVP), and changes in factorial relationships among the five DTVP subtest after a 10-week use of the program of M. Frostig. (MC)
