Thinking - An Introduction To Its Experimental Psychology

THINKING THINKING An Introduction to its Experimental Psychology GEORGE HUMPHREY Director of the Institute of Experimental Psychology and Professor of Psychology in the University of Oxford LONDON METHUEN CO. LTD. NEW YORK JOHN WILEY SONS INC, PREFACE THIS BOOK WAS begun in 1934 at the suggestion of Professor F. C. Bartlett. 1 The first draft was practically finished when war broke out, and for various reasons the book had to be laid aside for nearly ten years. The whole manuscript has now been revised and a good deal of it rewritten. Those who have read the manuscript in duplicated form at various stages have made many suggestions about its content. Some, for instance, have urged that the section on the Wiirzburgers, which now occupies three chapters, should be deleted or at least shortened. Others have been equally urgent that these chapters should be left intact. With the exception of some pruning where the argument seemed to have become diffuse, the Wiirzburg chapters have been left substantially as they were originally written, and for the following reasons. The contribution of this group still stands in its own right as the most massive, sustained, and acute experimental attack on the problem of thought. It is true that the vocabulary, and behind it the general theory, employed by these men is now out of date, and that for this reason their work often seems arid and devoid of significance for modern psychology. But actually they were concerned with a set of general problems that are still very much alive to-day. Of these, the most important can thus be stated Can organic response be reduced without remainder to response strictly correlated with individual receptors The problem has a long history and is still being debated. At the present time, for example, Hull and his pupils are maintaining a theory of behaviour built on the foundations laid by Pavlov, and which maintains that behaviour can be explained in terms of funda mentally unchanged motor response to specific receptoral stimula tion. 2 The controversy concerning imageless thought debated the same problem, couched, however, in terms of experience. The Wiirzburgers were concerned with the question whether Experience can be built up out of experiences referable to particular sense modalities. The problem is the same, though the co-ordinates have been changed. In the same way, the Wiirzburg workers found it 1 Now Sir Frederic Bartlett. 2 The controversy over the continuity theory of learning sprang of course from the original theory.
