The Blind Learning Aptitude Test.
Newland, T. Ernest
A Blind Learning Aptitude Test (BLAT) was developed on the basis of sense of touch rather than on conventional experience, fine sensory discrimination, or verbal competency. From a pool of about 350 items, most of them used in testing intelligence in the sighted, a pool of 94 was selected and embossed after the manner of braille. A residual pool of 49 test and 12 training items was selected through the responses of some 500 blind children. Normative data were gathered on the responses of 961 subjects. Analyses of the data indicated the following correlations for the BLAT: internal consistency, .934; test-retest reliability over 7 months, .865; and Hayes Binet mental ages, and Wechsler Intelligence Scale for Children verbal ages, .89 for the 420 children for whom preceeding scores were available. Although the BLAT was found to lose discriminative power at or near the 12-year level, it was suggested as being more valuable than the Hayes Binet or the Wechsler for younger children since it tests process rather than product behavior.
