| Abstract: | This teaching machine has been designed and used to train reading and other visual discrimination skills with normal and retarded children. On each frame the subject responds by touching one of three response panels on which are projected the multiple-choice alternatives. The response panels are coated with a transparent conducting film which allows electronic detection of this simple and direct response. Correct responses are reinforced by the machine naming the stimulus, while auditory reinforcement is absent for an incorrect response. The subject's performance level is continuously computed as an exponentially weighted moving average. The measure is weighted so that it rapidly follows recent changes in performance. |
