Two important events took place since the bulk of the material for our previous review (Guertin, Frank, & Rabin, 1956) was gathered and organized. The first is the publication of the manual for the revised WB, 2 known as the WAIS ; the second was the appearance of a new, rewritten, and reorganized edition of Wechsler's Adult Intelligence (1958).Although the manual was mentioned in our previous review, the new test it introduced-the WAIS-had not yet become the popular instrument it is today. It seems to be re-1 Through July 1960. 2 The abbreviation, WB, will be used throughout to indicate the Wechsler-Bellevue Intelligence Scale, Form I. Form II will be designated WB II, while WAIS signifies the Wechsler Adult Intelligence Scale. The names of the subtests also appear in abbreviated form throughout the paper.
