Excerpt from book: There was no magic in the verbal statement, however, as was shown by failure in a case where the rule was memorized without the performance of the analyses of which it was the expression. The generalized formula was most readily developed by those who had been trained in the logic of scientific method. The relative independence of analysis and imagery is shown by the double fact that, on the one hand, the mere presence of images directly related to the solution of the problem in hand was found to be of no avail unless the act of analysis were performed, and, on the other hand, that previous experience seemed to be effective in determining a perceptual analysis in which no trace of imagery could be found. The general point which it has been the aim of this section to maintain is that in place of merely contrasting extreme types of learning, such as the human and the animal, or of making a hierarchy of percepts, images and concepts, what is needed is a working out of the sorts of analysis which may occur within the perceptual field, and within the image field, whether factual or verbal, and, in connection with this, to determine more precisely the significance of the mental stuff, or fields, themselves. On this double basis it might be possible to exhibit the rich complexity of human forma of learning, and by means of this to catalogue the narrower but still surprisingly extensive range of animal methods. The gross characterizations would still have their value, but the finer distinctions would undoubtedly prove significant in precise evaluations. 2. Conditions Of Efficiency a. The Fact of Variations.?It seems to be pretty generally agreed that abrupt drops in time, in a given practise series, or sharp increases in score when the times are kept constant, are due to v...
