Performance on the Peabody Picture Vocabulary Test and Stanford-Binet by Institutionalized Mentally Retarded Children

Comparison of two receptive language tests (PPVT and TACL) used with the developmentally delayed

“…Fitzgerald, Pasewark, and Gloeckler (1970) further reported the PPVT overestimated the full scale IQ of the Wechsler Intelligence Scale for Children (WISC) in all but two of the twenty-two studies he reviewed comparing the WISC and PPVT with an educationally handicapped population. Supporting this view, Brown and Rice (1967), Burnett (1965), , Gensemer, Walker, and Cadman (1976), Pasewark, Fitzgerald, and Gloeckler (1971), Sattler and Anderson (1973), Silberberg and Feldt (1966), Throne, Kaspar, and Schulman (1965), Yells and Pedrini (1967), and Zunich and Tolley (1968) reported the PPVT IQ or mental 9 age to be significantly higher than the similar WISC or Stanford-Binet scores. Additionally, Allen, Haupt, and Jones (1964-) Conversely, numerous studies reviewed showed no significant difference between PPVT IQ's and mental ages and those resulting from the WISC or Stanford-Binet.…”
