Reanalysis of Wakefield and Carlson's data confirmed canonical correlations of .84 and .69, but analysis of redundancies revealed that only 34 percent of the total WISC subtest variance is redundant with the ITPA and 39 percent of the ITPA subtest variance is redundant with the WISC. (Author)

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 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.

One hundred fifty-seven trainable children (aged 7 to 14 years) in 24 classes were given language stimulation based on the Illinois Test of Psycholinguitic Abilities (ITPA) four or eight times a week for a 1 year period. Also examined were the effects of high and low IQ. Measures used were the ITPA, the Peabody Picture Vocabulary Test, and the…

Examines language scores of untreated disadvantaged four-year-olds on the Illinois Test of Psycholinguistic Abilities as a function of the Family Development Research Program testing style. Children in the program were more likely than other intervention project preschoolers to achieve near normal scores. (Author/BB)

This report discusses the practical problems encountered in a longitudinal study now in its fourth year, where the focus has been the early identification of later learning disorders. The general goal was the identification of tests with the characteristics of high reliability, low cost, short time to administer, low demand on scoring…

To examine the relationship of the Flowers-Costello Tests of Central Auditory Abilities and the Illinois Test of Psycholinguistic Abilities, 20 ethnic minority kindergarten children were administered both tests. (Author)

A comparative study between the Sioux children in this study and the white middle-class children used in standardizing the Illinois Test of Psycho-linguistic Abilities (ITPA) may reveal areas of distinctive differences between the 2 populations in specific language use. The 59 selected Indian children were from the Fort Thompson school, were…

The article describes the circumstances leading to the development of the Illinois Test of Psycholinguistic Abilities and discusses the malpractices in administration, scoring, and interpretation of the test. (Author)

Summarized are 68 research studies from 1970 to 1975 on the Revised Illinois Test of Psycholinguistic Abilities (ITPA), particularly as it relates to learning disabilities. The reviews have been organized by the following areas (the number of studies in each section and sample study topics are in parentheses): studies comparing the experimental…

The Illinois Test of Psycholinguistic Abilities (ITPA) is treated in terms of the ability measured, hints for administration and scoring, and questions often asked for each of the nine subtests. Typical profiles are described and analyzed for mentally retarded, kindergarteners, slow learners, culturally disadvantaged, Negroes, good and poor…
