tests were chosen because some age and educational norms 1 were available 

 for them and none of the six persons have taken any form of these two tests. 

 Tests affected less by information and education would have been preferred, 

 but did not otherwise comply with the requirements. 



The result confirmed the previous findings. All four sibs tested with very 

 high scores though the scores were in general less high. The father also had. 

 a high score and the mother, though less high yet showed a superior score. 

 The scores were in general less high in the elements of the "social intelli- 

 gence" test as of course the environmental factor is so much more potent 

 relatively in these tests than in the Detroit test which is a more typical 

 mental test. 



The work of the Civic Club Committee turns up additional siblings and 

 cousins of previous awardees at each test and it is planned to test additional 

 families of three or more sibling awardees with their parents as they are 

 discovered. 



The results of every mental test are in part determined by innate capacity 

 and in part by environmental factors. The relative proportion of the two 

 sets of factors is known to differ to a great degree in the various tests. In 

 this instance the environmental factors operate against the mother more 

 than the others as she did not attend college and has lived the life of the 

 house-wife rearing four children without a servant. The work of the hus- 

 band is that of Lecturer on Health Teaching in a University and a practic- 

 ing physician. The sibs, at the time of these tests were: (1) a son, gradu- 

 ated from college one year before (2) a son who had finished three years in 

 college (3) a daughter, who had just finished her senior year in high school. 



The results of the test are given in table 1 which differ as to the Detroit 

 test from the mimeographed abstract of this paper because of the receipt of 

 later norms based on larger series from Dr. Baker the author of the test. 



It is clearly seen that the sibs are almost uniformly very high, being 

 slightly higher than the father, more noticeably in tests where the more 

 recent schooling would be a factor, and higher than the mother who was 

 somewhat handicapped. 



Since age allowances and norms are necessary for comparison of the sibs 

 and these involve a considerable probable error (even though extrapolated 

 or other less applicable ones were not used) no stress is laid on the thirteen 

 items separately. The high scores on "logical relations" in contrast to the 

 "visual imagery" test make it desirable to test further as to these items. 



The real names of this family are available to anyone who might wish to
