Publisher's Synopsis
Excerpt from Some Phases of the Psychology of Puzzle Learning
As to Dr. Ruger's plan of keeping a record of false moves it is ex tremely improbable that it amounted to anything definite. With some Very simple puzzle forms a correct record of this nature might be kept, but it seems practically impossible to record all false moves when the puzzles are complex and 'when many of them are in three dimensions. This matter is dealt with in the report of original investigations found later in this book. It may be sufficient here to say that to know by watching what are truly false moves, to know when to count a partial move false, to know when to make allowance for moves inhibited al most as soon as begun, to know how to divide up a series of connected motions into a definite number of moves, to know just when to count a move false which, if having other antecedents would not be false, tobe able to act promptly and unerringly along all these and similar lines, and then to be able to keep an accurate record and for all sub jects a full and complete record of such observations, giving the same value tothe same form of move among all subjects alike, this is surely expecting the impossible. If, on the other hand, the record of moves is not kept as carefully and fully as here suggested it becomes merely a jotting of selected'and' partial observations and has no substantial scientific value. Here again Dr. Ruger seems implicitly to deny the value Of his own method, for in discussing the experiments he almost never makes any reference to this record of false moves.
