IQ Tasks Measure What the Individual Has Learned

This concept comes directly from Wesman's (1968) introduction of the intelligent testing approach. The content of all tasks, whether verbal or nonverbal, is learned within a culture. The learning may take place formally in the school, casually in the home, or incidentally through everyday life. As a measure of past learning, the IQ test is best thought of as a kind of achievement test, not as a simple measure of aptitude. Like the SAT, IQ tests assess "developed abilities, broadly applicable intellectual skills and knowledge that develop slowly over time through the individual's experiences both in and out of school...[that are] not tied to the content of any specific course or field of study" (Anastasi, 1988, p. 330).

The interaction between learning potential and availability of learning experiences is too complex to ponder for any given person, making the whole genetics-environment issue of theoretical value, but impractical and irrelevant for the interpretation of that person's test profile. Even the sophisticated scientific challenges to the IQ construct issued by Lezak (1988a) and Siegel (1999) or the emotional, less informed in dictments of IQ tests handed out by members of the public, become almost a side issue when the tests are viewed and interpreted simply as measures of accomplishment. The term achievement implies a societal responsibility to upgrade the level of those who have not attained it; the term aptitude implies something inborn and personal and can justify a withdrawal of educational resources (Flaugher, 1978).

Issues of heredity versus environment and the validity of the IQ construct are meaningful for understanding the multifaceted intelligence construct; the accumulating research helps test developers, practitioners, and theoreticians appreciate the foundation of the tests used to measure intelligence; and the IQ tests, as vehicles for the research, are essential sources of group data for use in scientific study of these topics. But all of the controversy loses meaning for each specific person referred for evaluation when the clinician administers an IQ test to study and interpret just what the person has or has not learned and to help answer the practical referral questions.
