SERRANO, Mario. Effects of three kinds of water delivery on behavioral adjustment. Acta comport. [online]. 2013, vol.21, n.3, pp. 273-283. ISSN 0188-8145.

Three groups of rats were exposed, respectively, to non-contingent water delivery, contingent water delivery, and water delivery according to a conditional discrimination situation using parametrically similar temporal schedules. Adjustment indexes regarding each type of contingency arrangement were calculated: differentiallity, effectiveness and accuracy. It was observed that in terms of both rates of development as well as terminal states, differentiallity indexes exceeded those of effectiveness, which in time were higher than accuracy indexes. These results are consistent with assumptions of progressive complexity and inclusiveness of Ribes and Lopez (1985) taxonomic proposal, and they are contrasted with those previously observed in this and other areas of the experimental analysis of behavior.

Keywords : adjustment indexes; non-contingent; contingent; conditional discrimination; rats.
