Discrimination of the own behavior
as a condition for the emergency of symmetry in pigeons. Andrés García and Santiago Benjumea Universidad Nacional de Educación a Distancia and Universidad de Sevilla, Spain When a human fellow is trained in a conditional discrimination, the symmetry emergency appears in a spontaneous way, this is, the fellow responds correctly when the sample stimuli and comparison are exchanged (Sidman, 1971; Sidman and Tailby, 1982). However, this result has not been obtained up to now in a consistent way with no-human fellows (Dube, 1993; Zentall, 1996). In the previous meeting of the EMEAB (Dublin, 1997) we present evidences obtained in our laboratory of the spontaneous emergency of symmetry in pigeons after a conditional discrimination. The fundamental difference of our procedure with the traditional training in equivalence classes consisted in that the sample stimuli were produced by the own behavior of the animal. Presently work enlarges our first experimental discoveries, making a study of the fundamental variables of the conditional discrimination under those that one obtains the symmetry emergency. This way, the importance of the number of responses demanded to the sample and the comparisons was analyzed, the simultaneous presence or not of the different samples or comparisons, as well as the importance of using the own behavior like sample stimulus. We finish considering the possibility that in those works in those that positive results are obtained with regard to the emergent relationships (they are with animals or human) they can have relationship with the phenomenon of discrimination of the own behavior.
