Resumo: |
This research aimed at investigating a procedure to install a chain of verbal responses that initiated verbal interactions about objects toys (non-verbal discriminative stimuli) , and that had varying topographies. Such chain had three links, and for each link three topographies were trained: (a) the first link was composed of the following topographies: What is this? , Which is the toy? , and What are we going to play with? ; (b) the second link consisted in the training of the following topographies: May I see? , Show the toy , and I want to see! ; and (c) in the third link the following topographies: I want to touch! , Give it to me. , and Can I play? . The emission of each link produced a specific natural consequence. The first was followed by the name of the toy hidden in the box; the second received as consequence the visualization of the toy, and the third produced access to the toy and the possibility of playing with it for 20 seconds. A procedure of training of fading out of the verbal model for the responses that should be installed was used. In such procedure the researcher provided, at first, the complete verbal model for the sentence (step 1) and the participant emitted anechoic response; gradually, parts of the model were withheld (in several steps), and the participant s responses were transferred to an intraverbal control. Applying a multiple baseline design between topographies, the training, carried out in individual sessions of approximately 40 minutes, was started with the last link in the chain. At first, two topographies in this link were trained, and at the end of the training, a procedure to establish variability of the responses was carried out. In such procedure, named variability training I, the reinforcer was delivered only when the response topographies varied in relation to the response emitted in the previous attempt. Then both trainings fading followed by variability I were carried out for the topographies in links 2 and 1. During training, all the links in the chain took place in each attempt, either on baseline condition or on training condition (that was maintained for the links already trained). Finally, another procedure to establish variability, variability training II, was carried out in order to generate responses differing from the ones that had been trained. In this procedure, the training for a third topography for each link was carried out. Once the training was over, two generalization test sessions were carried out for two of the participants. The first of such sessions was held by another researcher, and the second was carried out by the same researcher present at training in a setting that was different from the one in which the training sessions were held. Results indicated that the procedure of fading out of the verbal model was effective in installing the nine different topographies of spontaneous verbal responses. However, the number of independent responses in the three topographies of each link varied; usually there was a preponderance of one of the trained topographies. Among the links, topographies referring to the third link in the chain, that produced access to the toy, were the most emitted. The variability I procedure generally produced variation in the trained topographies, manly in the second and third links of the chain. It is possible to say that the responses of topographies that were not trained were emitted more frequently after variability II training, in spite of this happening before this training, especially in the case of one of the participants. There was evidence of the effects of variability trainings I and II, carried out in one link of the chain, over the varied responses of the other links. During the generalization tests, the participants did not emit three of the trained topographies (two in the first link and one in the second), and the most emitted were the ones in the third and second links in the chain |
