BAIA, Fábio Henrique et al. Operant lineages and culturo-behavior lineages: An experimental demonstration. Rev. Psicol. UNESP [online]. 2013, vol.12, n.1, pp. 1-12. ISSN 1984-9044.

This study has investigated the possibility of laboratory demonstration of operative and cultural lineages. The operant lineage describes that in a certain class of responses some topographies of responses become more frequent than the other members of this class. The culturo-behavior lineages are (1) socially learned behaviors that (2) continue to be replicated in the repertoire of new organisms and whose (3) consequences produced are sufficient to maintain their recurrence besides (4) maintaining the control relationship by previous environmental events similar to those that evoked the original operative. Six university students took part of the study. The experimental task involved the insertion of numbers in a math task. The participants performed the task in pairs with permission of verbal interactions. We measured the digits entered by the participants as defining properties of the topography of the responses. The results indicated that, in general, response topography became more frequent inside a universe of five possible topographies for reinforcement. A replication of such topographies was also observed for social learning. It was concluded that it was possible to observe, in laboratory, the occurrence of operant and culturo-behavior lineage.
