Abstract : Three attempts were made with rotary pursuit apparatus to induce decrements in performance subsequent to interpolated practice. An ordinary Koerth-type rotor was first employed with mirror-vision practice preceding direct-vision practice. Mirror-vision performance during relearning was not adversely affected by the interpolated practive. With the Double-Disk Pursuit Apparatus, subjects learned to trace a kind of figure-eight pattern. Original practice with the disks rotating in one way was followed by practice with the directions of rotation reversed. The decrements that appeared at the outset of relearning were small and could not confidently be attributed to interference effects. A second model of the Double-Disk Pursuit Apparatus provided for a variable pursuit pattern. The change in the tasks, as between original and interpolated learning, depended upon a reversal of the directions of rotation of the disks. Here again, a decrement appeared at the outset of relearning, but it was too small to be clearly identifiable as a product of interference. (Author)
