Order of Experimental Conditions and Empirical Parameters of the Generalized Matching Law

Abstract

Three experimentally naive pigeons were submitted to concurrent variable-interval varlable-interval schedules in a three-key procedure. A variable-interval 60 s schedule was always associated with the right/blue key. In different experimental conditions, the variable interval schedule associated with the left/red key was varied in the following orden 240, 180, 300, 360, 90, 60, and 15 s. In spite of te non-recommended order of experimental conditions, exponents of te generalized niatching equation show rnatching of response ratios to reinforcement ratios.
