The Stanford–Binet Intelligence Test for Turkish Primary School Blind Children: Variables Related to IQ

Abstract

In a normative study, the Stanford-Binet Test of Intelligence was administered to 142 blind, primary school children ages 7 to 11. The IQs obtained from this study was the dependent variable in a multiple regression analysis using several sets of predictor variables. Urban/rural background, and age at onset of blindness tended to be related to IQ in the expected direction but not significantly so. School, class placement, age, teachers’ ratings of auditory memory skills and self-help dressing skills accented for 62 percent of the IQ variance giving a multiple correlation of .78. Other variables did not add significantly to the equation. The findings of this study are remarkably similar to those generally found in research on intelligence tests in America and, more specifically, in research on the blind.
