The development and standardization of the Chicago Non-verbal Examination

Abstract

An intelligence test was devised for use with deaf children, children who have language and reading difficulties, and adults with similar handicaps. Only material was selected for the test which could be administered by pantomime directions intelligible to first- or second-grade children, and which had a wide enough range of difficulty so that some was easy enough for 6-year-olds and some sufficiently difficult for superior adults. The test-retest reliability was found to be .92. Correlations obtained between test score and age ranged from .57 to .81, and with other intelligence tests from .51 to .82. Groups of mentally retarded children were found to have about the same rating on this test as on the Stanford-Binet. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
