In recent years the widespread use of intelligence tests in the school age population has been strongly criticized. The most prevalent criticism of these tests is that the result­ing IQ scores are verbally based. Those who criticize these tests say that the verbal portion may not be fair to members of subcultural groups because of differences in language expe­riences in their backgrounds. While most of the complaints about the inequalities of intelligence testing revolve around this idea, the fact that our society is a highly verbal one is recognized and accepted. Many investigators say that people with different cultural backgrounds may have some peculiar condition of perceptual or learning set that causes their understanding of verbal behavior to be different from that of the norming groups, and not related to intellectual deficits.
