An experiment "to test the efficacy of the two factors—head position and position of the object in the visual field—in making a localizing arm reaction to a fixated object." When the head was turned to the right of the line of sight the object was localized (by pointing) to the right of the true position, and when turned to the left the localizations were to the left. Least errors were made when the objects were in the central retinal position. The size of the errors increased in the periphery, the direction of the error corresponding to the position of the object in the visual field. No quantitative relations are given.
