The data they discuss in this paper are taken from an earlier one (2). This was the instance mentioned previously, in which S scores, here elaborately analyzed, were initially no better for the experimental groups than for a control group which had not read the passage. Both groups scored slightly less than chance alone should have made possible. * Of the S items 8 fall in the first quartile (greatest difficulty), 8 in the second, 3 in the third, and I in the fourth; of the V items, 2 are in the first quartile, 2 in the second, 7 in the third, and 9 in the fourth.
