Note 217 — THE MENTAL LIFE OF THE DOMESTIC PIGEON
Reading edition
From the tables (op. cit., pp. 330-339) it seems that the right choices for position, color, and form, were respectively, 40%, 58% and 20%. The comparatively small number of correct position choices was probably due to his using ten boxes instead of six, as in the other two series. My results given in Table XI were secured under almost exactly comparable conditions. Compare results of Kinnaman in case of the Rhesus monkey, op. cit., pp. 130, 131, 134, 141, and 177.
