Interdependência entre Aquisição e Produção de Mandos, Tatos e Intraverbais.

Abstract

This study aimed to investigate: (1) Which verbal operant would be first acquired (tact, mand or intraverbal) and, (2) if a response established under mand conditions would occur under tact and intraverbal conditions without direct training, if a response established under tact conditions would occur under mand and intraverbal conditions without direct training and, if a response established under intraverbal conditions would occur under tact and mand conditions without direct training. The subjects were six normal children from three years and half to four years and half. The experiment began with one baseline session where echoic responses were tested. Then, three baseline sessions were applied to test mands, tacts and intraverbals. Following each one of the three operants were trained for each subject using specific stimuli. Prompts, fading, tangible reinforcers and other special training procedures were used when required. As the subjects reached criteria the other operants which were not trained with the stimuli used in this phase were tested. The results showed that tacts and intraverbals were first acquired in the training conditions and, the findings also showed greater interdependence between mands and tacts, fewer interdependence between tacts and mands, and between mands and intraverbals and, hardly no interdependence between intraverbals and mands and between intraverbals and tacts and, between tacts and intraverbals.
