The results were now very interesting. During the month ending June 15th the child showed no decided preference for either hand in reaching straight before her within the easy reaching distance of ten inches, but a slight balance in favour of the left hand; yet she was right-handed to a marked degree during the same period as regards movements which required effort or strain, such as grasping for objects twelve to fifteen inches distant. For the greater distances, the left hand was used in only five cases as against seventy-four cases of the use of the right hand; and further, all these five cases were twelve-inch distances, the left hand being used absolutely not at all in the forty-five cases at longer distances. In order to test this further, I varied the point of exposure of the stimulus to the right or left, aiming thus to attract the hand on one side or the other, and so to determine whether the growth of such a preference was limited to experiences of convenience in reaching to adjacent local objects, etc. The deviation to the left in front of the body only called out the right hand to greater exertion, while the left hand fell into still greater disuse. This seems to show that "dextrality" is not derived from the experience of the individual in using either hand predominantly for reaching, grasping, holding, etc., within the easiest range of that hand. The right hand intruded regularly upon the domain of the left. Proceeding upon the clew thus obtained, a clew which seems to suggest that the hand preference is influenced by the stimulus to the eye, I introduced hand observations into a series of experiments already mentioned above on the same child's perception of the different colours; thinking that the colour stimulus which represented the strongest inducement to the child to reach might have the same effect in determining the use of the right hand as the increased distance in the experiments already described. This inference is proved to be correct by the results. It should be added that in all cases in which both hands were used together, each hand was called out with evident independence of the other, both about the same time, and both carried energetically to the goal. In many other cases in which either right or left hand is given in the results, the other hand also moved, but in a subordinate and aimless way. There was a very marked difference between the use of both hands in some cases, and of one hand followed by, or accompanied by, the other in other cases. It was very rare that the second hand did not thus follow or accompany the first; and this was extremely marked in the violent reaching for which the right hand was mainly used. This movement was almost invariably accompanied by an objectless and fruitless symmetrical movement of the other hand. The results of the entire series of experiments on the use of the hands may be stated as follows, mainly in the words in which they were summarily reported some time ago:
