Investigating the effects of a long history of continuous reinforcement of an alternative behavior of the one specified by a rule on subsequent discrepant rule-following, 08 undergraduate students were exposed to a matching-to-sample procedure. The task consisted of pointing, in a sequence, to each of three comparison stimuli that had only one thing in common with the sample stimulus and differed in other characteristics. The experiment had four phases. Phase 1 was baseline. Phase 2 begun with a rule corresponding to the contingencies. Phase 3 had an un-signaled change in the reinforcement contingencies, and Phase 4 started with discrepant rule. The results showed that on Phase 1 most of participants had a variable performance. On Phase 2, all participants followed the corresponding rule. On Phase 3, six participants continued to follow the rule of the previous phase and two participants emitted the correct sequence. On Phase 4, four participants followed the discrepant rule; three abandoned rule-following and began to emit the correct sequence; and one abandoned the discrepant rule, but began to emit a sequence that wasn’t reinforced. The data suggests that the participants that presented behavior under rule control on Phases 3, tended to follow the discrepant rule on Phase 4; and, the participants that showed a behavior under control of immediate consequences on Phases 3, tended to abandon the discrepant rule-following on Phase 4. The role of the history of behavior alternative to the one specified by the rule is discussed.

Efeitos de histórias do ouvinte sobre o seguimento de regras discrepantes das contingências

Testing proposition by aiming on the listener’s history critical characteristics that may meddle on the discrepant-rule following, eight college students were exposed to a matching to sample procedure. The task was to point to the three comparison stimuli in a sequence. In Phase 1 no sequence was instructed or reinforced. Phase 2 begun with the rule corresponding to the contingencies. Contingencies effective in Phase 2 were shifted without warning in Phase 3. Contingencies in Phase 3 were kept unchanged in Phase 4, which started with the presentation of a discrepant rule. Six out of eight participants showed an independent behavior and two out of eight showed a dependent behavior from its immediate consequences in Phase 3. From those six out of eight participants showing an independent behavior, four managed to follow the discrepant-rule in Phase 4. And from the latter two out of eight showing a dependent behavior, all of them abandoned the discrepant-rule following in Phase 4. It is suggested that the behavior’s dependence and independence to its immediate consequences, before the discrepant-rule presentation, are critical variables of the listener’s history that may be used to foresee maintenance, or not, from the subsequent discrepant-rule following.
