PART III GENERAL PRINCIPLES AND IMPLICATIONS
CHAPTER EIGHTEEN ADULT STATUS AND PERSONALITY RATINGS
Observation of such cases as those described in the foregoing chapters suggests that children of exceptionally high intelligence do not regress toward mediocrity as they mature but maintain their initial distinguished status. Studies by other workers (Kuhlmann, Baldwin and Stechner, Terman) confirm such a conclusion. A further study of this point was reported by Hollingworth and Lorge in 1936, in which the following questions were investigated:
1. To what extent is status in IER Intelligence Scale CAVD at maturity predictable from childhood scores in Stanford-Binet?
2. How do those who tested above 180 IQ in childhood differ at maturity from those at lower levels in measures of general culture and of scientific information?
3. Is there discernable any consistent specialization in mental abilities from childhood to maturity?
4. At what degree of intelligence in terms of IQ (Stanford-Binet) is the word "genius" justifiable, if at all?
5. At what point on the scale of IQ (Stanford-Binet) obtained in childhood will individuals later prove "unmeasurable" by available tests of adult intelligence?
In 1934-1935 a group of eighteen persons whose high IQ's had been measured tweleve or thirteen years earlier (at ages 7 to 9 years) were measured in these respects and to these were added three others whose childhood IQ's were known to have been over 170. The tests used, to be reported here, were: CAVD Intelligence Scale, Levels N-Q; the Coöperative General Culture Test (Form 1933 or 1934); and the Coöperative General Science Test (Form 1933). There were also available data on most of the individuals from Army Alpha tests taken at ages 16 to 19. Of the 21 cases thus studied, nine had a childhood IQ over 170; eight over 150 [to 170]; the remaining four ranged down to 133.
ADULT STATUS OF HIGHLY INTELLIGENT CHILDREN [1]
The detailed data have been reported elsewhere and only the general results need to be recited here.
"For these gifted individuals (albeit there are so few studied) superior status on the Stanford-Binet at or near ages 7 to 9 years of age is highly predictive of status on Army Alpha at or near 16 to 19 years of age, and of status on CAVD at or near maturity. . . .
