This book deals with one aspect of the modern, proof, and the deductions to which they give rise, and scientific study of intelligence, namely its measurement. the social aspect, which is concerned with the "good" or The term, measurement, has difficulties attached to it "evil" consequences which follow from the scientific which rival those attached to the term, intelligence; discovery or invention. Thus IQ testing would appear to many psychologists have little idea of what the word many people to give rise to desirable and "good" conse means, and what are the requirements which must be quences when it enables us to pick out bright "dis fulfilled in order to enable "measurement" to take advantaged" children for higher educational and place. Krantz, Luce, Suppes and Tversky (1971) have university training who would otherwise not have been tried to provide us with an introduction to the "Founda educated up to the level of their ability. On the other tions of Measurement"; these two volumes outline the hand, IQ testing would appear to many people to give background against which attempts to measure intelli rise to undesirable and "bad" consequences when it gence must be evaluated. * No short excerpt or set of enables trade unions to exclude coloured workers by the readings could suffice to bring home to the "innum imposition of unrealistic and irrelevant intellectual erate" reader the implications of scientific measurement, requirements for membership.

As the pastPresident ofthe Israel Society forAutism, it gives me great pleasure to c- gratulate Professor Schopler and his colleagues on the publication of their new book concerning the relationship between scientific research and treatment. When we in Israel began our specifically structured education program for young children with autism, our work was based on slim to scarceknow-how andinformation, and with no experience whatsoever. Whatever information we could gather was mostly from psychological educational centers in the U.S. One of the most important and significant connections was established between the TEACCH program of North Carolina, led and conducted by the two important scholars, Professor Eric Schopler and Professor Lee Marcus, and our Israel Society for Autism. During our many encounters, seminars, and conferences, we profited enormously from all their accumulated expertise and scientific research, while perhaps it was also an important experience for them to see how a young society with very limited means was eventually shaping its educational program and arriving at some excellent results. We, ofcourse, have the highest esteem for Governor Hunt who has been following this program with so much attention and support, and we still remember his visit to Israel with distinguished representatives of the TEACCH Program. I wish the new book every success. I know it will be an enormous contribution to all those who must cope with a difficult and painful issue—autism—for whom there is no end to the need for research and continuously improving methods of care and education.
