Resurgence is the reappearance of an extinguished operant response when an alternative behavior is subsequently treated with extinction (Podlesnik & Shahan, 2009). A potential solution to this problem is training serial alternative responses. During the present study, undergraduate students were trained to engage in an arbitrary response analogous to problem behavior and two alternative responses. Each response was reinforced for a distinct duration to establish different reinforcement histories and then tested under conditions of resurgence. The purpose of the present study was to evaluate the effects of duration of reinforcement on behavior subsequently exposed to resurgence contingencies. Three subjects engaged in the target response most often, five subjects engaged in alternative responses most often, and one subject engaged in all response equally during resurgence.

Despite the variability of behavior have made it the object of working study in operant literature, there are few studies which demonstrates the introduction of a baseline for evaluating the effects of manipulation of variables. The study objective was to investigate the variability acting as a property of behavior from an experiment that sought to verify in a 5 x 5 matrix, sequences of answers delivered in a Baseline 1 in experimental stages of training, where the variable was manipulated and a Baseline 2. A second experiment was done to check if the responding keeps in terms of strengthening the contingent variation / repetition, and the extinction (FR = 0) maintains or differs responding issue and interfere in the model of variability. The data have been supported at the selection by consequences model and also characterizes behavior variation/repetition as an operant. The present study concludes which variability is maintained in function of the reinforcement. / A variabilidade produzida a partir de reforçamento contingente a variação e/ou repetição de respostas tem sido investigada em análise do comportamento. Apesar de a variabilidade comportamental ter tornado-se objeto de estudo na literatura operante, poucos são os estudos que apresentam a introdução de uma Linha de Base para verificar a construção da história durante o responder em variação e repetição do participante. O objetivo deste trabalho foi investigar a variabilidade como uma propriedade operante do comportamento a partir de um experimento que procurou verificar em uma matriz 5 x 5 as seqüências de respostas emitidas em uma Linha de Base 1, em fases experimentais de Treino, onde houve manipulação experimental e exposição à uma Linha de Base 2. Um segundo experimento foi feito a fim de verificar se o responder fica em função do reforço contingente a variação/repetição, se a extinção (FR=0) mantém ou difere o responder e interfere na variabilidade. Estes dados são apoiados pelo modelo de seleção por conseqüências e caracteriza a variação e repetição do comportamento como um operante. O presente estudo teve como conclusão que a variabilidade é mantida em função de reforçamento.
