Intelligence Measurement: A Psychological and Statistical Study Based Upon the Block-design Tests'What is the nature of mind?' This question, propounded when man first became conscious of himself, still remains but inadequately answered. Nevertheless, some evident progress has been made. The light of scientific progress is gradually penetrating the various nooks and recesses of our mental life, and the machinery of thought, although dimly revealed, is becoming more apparent in its operation. This monograph is but a mere fragment, explaining little if anything regarding the dynamics of mental process, yet it hopes to place a variety of perplexing problems in a new perspective. We shall have occasion, for example, to examine some current definitions of intelligence, and we shall indicate wherein our research into the value and significance of completion and combination tests forces us to a reconsideration of the criteria of intelligence and to a restatement and a redefining of some fundamental principles. |

Page 21 - We all cease analyzing the world at some point, and notice no more differences. The last units with which we stop are our objective elements of being. Those of a dog are different from those of a Humboldt ; those of a practical man from those of a metaphysician. But the dog's and the practical man's thoughts feel continuous, though to the Humboldt or the metaphysician they would appear full of gaps and defects.
Page 18 - I have had to invoke, in order to explain the improvement of certain discriminations by practice, the "association" of the objects to be distinguished, with other more widely differing ones. It is obvious that the advance of our knowledge must consist of both operations; for objects at first appearing as wholes are analyzed into parts, and objects appearing separately are brought together and appear as new compound wholes to the mind. Analysis and synthesis are thus the incessantly alternating mental...
Page 20 - ... some people are far more sensitive to resemblances, and far more ready to point out wherein they consist, than others are. They are the wits, the poets, the inventors, the scientific men, the practical geniuses. A native talent for perceiving analogies is reckoned by Prof. Bain, and by others before and after him, as the leading fact in genius of every order.
Page 68 - Kohs' test material consists of two parts: (1) sixteen color cubes; these "cubes of one inch dimension are all painted as follows: one side red, one side blue, one side white, one side yellow, one side blue and yellow (divided diagonally), one side red and white (divided diagonally)" (64); (2) seventeen designs "graded in difficulty which increases by mod1fying the designs at various stages
Page 21 - ... feel continuous, though to the Humboldt or the metaphysician they would appear full of gaps and defects. And they are continuous, as thoughts. It is only as mirrors of things that the superior minds find them full of omissions. And when the omitted things are discovered and the unnoticed differences laid bare, it is not that the old thoughts split up, but that new thoughts supersede them, which make new judgments about the same objective world.
Page 261 - The range of the delinquent group was found to be practically coextensive with that of the army group, our most representative sampling of the general population. Further, the difference between the means of the delinquent and the non-delinquent groups, while affording adequate indication of...
Page 19 - ... distinction of the general or universal from the particular. To compare is always to compare in some special respect. Some theoretical or practical end is to be subserved by the comparison. The difference or agreement to be discovered is not any difference or agreement, but one which has significance for the guidance of conduct or for the solution of a theoretical difficulty. Thus comparison takes place only in regard to the characteristics which happen to be interesting at the moment, other...
Page 176 - That this new test measures intelligence "there seems to be no reasonable doubt, substantiation having been obtained through introspections, that these tests require first, the breaking up of each design presented into logical units, and second, a reasoned manipulation of the blocks to reconstruct the original design from these separate parts. The results of this activity, it is presumed, yield a fair index of this analytic-synthetic power which we have termed 'intelligence'
Page 261 - Summarizing, then, the results of such comparisons as we have been able to make of the mental capacity of delinquent women with that of non-delinquents, it appears: (1) That the average mental capacity of the delinquent women whom we have examined is lower than that of any groups of nondelinquent adults with regard to whom we have data.
Page 14 - The organism which is gTfied with intelligence shows it by arranging its actions on a certain plan. It adapts means to ends, which is one sort of correlation, and in so doing it perhaps brings a past experience to bear, interpreting a perception, for example, by memory ; and this is another sort of correlation.
