The performance of five aphasic patients was rated on three tests of language ability: The Minnesota Test for  Differential  Diagnosis; Luria's Tests of aphasia; and a Test of expressive language based on graded stimuli from the Peabody Picture Vocabulary Test. In order to assess communicative-ability of the subjects, each expressive language sample was administered to four judges and a score of communicative success was computed. The study aimed at comparing each subject's performance on these tests of aphasia and its relationship to the degree of communicative success, in an attempt to ascertain which test is the most accurate predictor of  "amount" of aphasic impairment. It also aimed at extracting those variables most useful and appropriate in the diagnosis of the impairment found in aphasic patients. Inter-test correlations revealed that tests of aphasia appear to be accurate predictors of "amount" of communicative success. Inter-item comparison revealed fourteen sub-tests which indicated greatest difference in the performance of all the subjects.

Symbol Use

13 children with a diagnosis of autism and 20 children with a diagnosis of childhood schizophrenia or a variant thereof were compared for skill in symbol use across modalities of expressive language, drawing, gesture, and play. The children were also given the Peabody Picture Vocabulary Test—Revised as a measure of receptive comprehension. Analysis showed that the autistic children had poorer receptive language than the schizophrenic children. The autisic children were poorer in symbol use, as predicted, across all expressive modalities except play, when receptive language was treated as a covariate. Implications of these results for differential identification of children with severe developmental disturbance are discussed.

Intellectual Abilities

There has been some question as to what the Peabody Picture Vocabulary Test measures. Although research indicates it has inadequate validity as a test of intelligence, other studies indicate it is an adequate measure of language ability. The present study correlated and factor analyzed the results from the Peabody test with results from a measure of linguistic and intellectual functioning. The analysis indicates that the test is not an adequate measure of either linguistic or intellectual abilities.

Language Sample

The Type-Token Ratio (TTR), a measure of lexical diversity, was correlated with four measures of vocabulary performance: the Peabody Picture Vocabulary Test-Revised, the Oral and Picture subtests of the Test of Language Development, and the Test of Written Language. The vocabulary tests were administered to 21 6-, 7-, and 8-yr.-old children from whom language samples were obtained for the application of three Type Token Ratio measures: the TTR-Total for the whole language sample, the TTR-100 for language samples of 100 words, and the CTTR, a procedure intended to be independent of language sample size. One correlation of .45 (between the CTTR and the Oral-TOLD) was significant. More research on validity is necessary to clarify the measurement domain of the TTR, if it is to be useful clinically.

It has been our experience in using the Peabody Picture Vocabulary Test that an inordinate number of verbs are missed by mentally retarded individuals. This study attempts to determine whether verb errors were due to a lack of word comprehension or a failure to understand what was being requested by the morphological-syntactic form of the stimulus. Twenty-eight subjects residing in a state facility for the mentally retarded were given a standard version and a modified version of the PPVT. On the modified version of the test, the stimulus "verbing" was altered to incorporate a syntactic helper, forming the stimulus "somebody verbing." As a result, there was a mean reduction of verb error by almost 50%.

Peabody Picture Vocabulary Test

The contribution of individual differences in physiological arousal to intellective assessment in learning disabled children was studied. Arousal was measured by salivary response and intellective function (receptive vocabulary) by the Peabody Picture Vocabulary Test. It was predicted that best performance would be found at intermediate levels of arousal. Peabody scores of learning disabled subjects of high, middle, and low arousal showed a non-significant trend in the predicted direction. Reasons for the lack of significance of this hypothesized trend were proposed and needed research outlined.

Relationship Of

Comparisons of the Peabody Picture Vocabulary Test—Revised and the Wechsler Intelligence Scale for Children—Revised were made with 104 children diagnosed as learning disabled and mentally retarded. Significant but modest correlations were found between all but one of the WISC—R scaled scores (i.e., Coding) and PPVT—R standard scores, and between WISC—R IQs and PPVT—R standard scores. Significant differences were found among mean Verbal, Performance, and Full Scale IQs and mean PPVT—R standard scores. The PPVT—R standard scores underestimated WISC—R Verbal IQs by 7 points, WISC—R Performance IQs by 17 points, and WISC—R Full Scale IQs by 11 points.
