What are the steps and decisions rules involved in imitation training?
Assess or teach the necessary prerequisite skills for imitation (attending, decreasing problem behaviors that will interfere). Select models: pick about 25 gross or fine motor movements. Pretests the responses to the models� have the learner seated attending, take the same position, put the same objects in front of you and the learner, say his/her name, and �do this,� do the model behavior, praise and reinforce responses with formal similarity to the modeled behavior ASAP, record what th response was keep pretesting until each movement has been done about three times. Dequencing the selected models: first in line are the models that the learner got right on some trials, Second in line should be the models that the learner approximated during the pretest. Finally the last tiems in the sequence should be those that the learner did not know at all. Do a pre-assessment at each training session and record responses. The learner must get a model right three times in order to remove it from it from that training session. During the training: repeat presentations of models, use physical guidance, and fade out the guidance cues gradually. Include a model in the postassessment when the learner gets it right without prompting for five consecutive trials. Postassement: present 5 previously learned models and 5 models currently included in training three times each. A behavior will be removed from training when the learner responds correctly without help to model 14 out of the 15 opportunities. Probes for imitative behavior: use about 5 non-trained, novel models thrown into the training sessions without the use of the verbal response prompt or any other guidance. This will help you tell if the learner is learning to do what the model does in general�not just the repeated items.
