Uma análise behaviorista radical dos sonhos
(2000) SILVA, Francynete Melo e
In spite of the fact that there is no consensus concerning questions about the nature and origin of dreams, the majority of the studies on the nature of the dreams agrees that they are related to internal conditions of the organism. As opposed to that notion, the radical behaviorism analyses the dreams as private behaviors and, thus, as products of philogenetical, ontogenetical, and cultural histories. In this sense, this paper aims to analyze the dreams from a radical behaviorism perspective, considering them as private events, perceptual behaviors, and arguing that they are learned processes. It is asserted that the dreams interpretation is impossible if the contingencies that control such activity are unknown.

Efeitos da exposição a mudanças nas contingências sobre o seguir regras
(2006-04) ALBUQUERQUE, Luiz Carlos de; SILVA, Francynete Melo e
By investigating the effects of experimental histories on discrepant rule following contingencies, nine university students were exposed to a matching-to-sample procedure; the task was to point out, in a set order, it one of three comparison stimuli. Each condition comprised four sessions. The contingencies in Session 1 were altered in Session 2, reestablished in Session 3 and remained unchanged in Session 4, which began with the discrepant rule. The three conditions differed as to the form of establishment of the alternative behavior to that specified by the discrepant rule. Independent of how the behavior was established in Session 1, whether by contingencies (Condition 1) or by rules (Conditions 2 and 3), only those participants who responded correctly in Sessions 2 and 3 (n = 7) did not follow the discrepant rule in Session 4. It is also discussed some of the characteristics that an experimental history should have to interfere with discrepant rule following.

Efeitos de perguntas e de histórias experimentais sobre o seguir regras
(2006-08) SILVA, Francynete Melo e; ALBUQUERQUE, Luiz Carlos de
Investigating the effects of continuous reinforcement questions and histories on rule following, nine university students were exposed to a matching-to-sample task which was point out, sequentially, each one of three comparison stimuli in the presence of a contextual stimuli. The contingencies in Session 1 were changed in Session 2, reestablished in Session 3, and kept unchanged in Session 4, which began with the discrepant rule. No questions were made in Condition 1, whereas in Conditions 2 and 3, questions were asked. In Condition 2, the questions were more general than in Condition 3. Only five participants (two of the Condition 2 and the three of Condition 3) learned the task and performed in accordance with the contingency-based changes. Of these five, four stopped rule following in Session 4. The results should lead to clarify the role of the verbal environment in the determination of non-verbal behavior.
