In an effort to relate skin resistance to recall scores, two experiments, the second a replication of the first, presented male Ss with 30 pairs of meaningful words. There were 18 Ss in Exp. I and 32 in Exp. II. Each pair of words was presented once for 10 sec., with an interval of 10 sec. between pairs. Following this, there was a 6-min. delay before the reordered left-hand items were presented, 10 sec. at a time. The S was initially instructed to give as many of the right-hand items as he could remember, guessing if he wished. Skin resistance was continuously recorded throughout the experimental session and later converted to log conductance. The data from Exp. I suggested that moderate levels of skin conductance in the first minute of the learning session were related to better recall. This relation was substantiated at a highly significant level (P < .01) in Exp. II. It was also found that moderate levels of conductance in the first minute of the recall period were optimal.
