Olson makes a fair restatement and analysis of the Haslerud and Meyers study except where he fails to see the necessity of dealing with different initial bases and the correlation in the data from the same Ss and the same 20 principles on Tests 1 and 2. That the "given" principles were less maintained and available than the "derived" on the transfer test was corroborated by a subsequent item analysis of the original data.
