Jackknifed Classification* Matrix Copy Incidental Accuracy, Immediate Recall Incidental Accuracy, Copy Structural Accuracy)	Correct Classification	Control (n = 12)	Experimental (n = 11)

Wilks’ Lambda = 0.7234; df = 3,19; F = 2.42; p = 0.10. Jackknifed classification* efficiency is calculated by sequentially eliminating one case at a time, computing the discriminant function based on remaining subjects, and using the resultant discriminant to classify the eliminated case. Percent correct classification is based on the overall success of the total sample’s cumulative classification in this manner.
