Excerpt from The American Journal of Psychology, 1892, Vol. 5 The preliminary experiments suggested other questions, which stood in such close relation to the ones at issue that their investigation seemed desirable. It has been thought best to first introduce some of these experiments, which really came later in the series, as in many cases they have a bearing on the others. For some time I have been convinced that it is a wrong method to take reactions of one or possibly two kinds, on certain days, and finish those of one sort before beginning the others. Reactions whose results are to be placed in imme diate comparison with one another should be taken on the same days, and the order of succession of the different kinds should be changed from day to day, so that the disturbing influences of weariness, practice, and other less easily con trolled conditions, may, so far as possible, be eliminated or equalized.
