Abstract
The effect of verbal descriptions and different amounts of consequences on the acquisition and transfer of a first order matching-to-sample response, as well as rule-formulation, was assessed. Twenty undergraduate students were assigned to four groups, which differentiated regarding the inclusion of incomplete texts and feedback at the end of each session. The rules, wrote down at the end of each session, were analyzed using categories derived from previous studies. The effects were observed at the response acquisition during the trainings and tests. It is discussed that an effective performance does not always lead to precise verbal descriptions and the instructional effect of the incomplete texts upon the formulation of effective rules.This journal is registered under a Creative Commons Attribution 4.0 International Public License.
