Subclaims¶

q2 i? 78 percent of six-year-old children pass the six-year individual tests while only 60 percent of them pass the six-year group tests, a difference the author attributes partly to children's need to comprehend orally presented directions without individual help. → Lowell 1917

Comparison of Table III percentages passing at age: Kuhlmann's individual test data (C.A. 6-9: 78, 73, 68, 64) against the author's group test data (60, 69, 72, 68), for children in the survey county schools.

"Thus, 78 per cent, of the six-year old children pass the six year individual tests, and only 60 per cent, of them pass the six year group tests."

• Several of the group tests (Discriminating Colors, Mutilated Pictures, Tying Bowknot) showed little discriminative capacity as group tests and are slated for substitution — related
