Pratt, J G (1953). Position
effects in the Stewart ESP data. Journal of Parapsychology, 17, (pp.
115-136) Abstract The ESP records of one of S. G.
Soal\'s high scoring subjects, Mrs. Stewart, were analyzed for consistent
variations in scoring in relation to the smaller structural units of the
highly routinized tests. The record sheets consisted of two columns, A and
B, of 25 trials each. A highly significant decline in scoring was found as
the subject proceeded through column A, and a significant general variation
in success was obtained in column B. In column B, there was a significant
difference between the successes on the odd-nmubered and the even-numbered
trials, the latter as a group giving much the higher rate of scoring.
