The present study tried to distinguish 2 groups of aware Ss in verbal conditioning: those who acquired the concept of the item to be conditioned and those who were only aware of the contingency between the item to be conditioned and the reinforcement. Through interview, the Ss were classified into unware Ss (No awareness group), Ss who were aware of the contingency only (Association group) and Ss who acquired the concept (Concept group). The main results were as follows: (a) Successful conditioning occurred only in Concept group. (b) Both No awareness and Association groups did not show a significant increment of performance on acquisition trials. (c) There was no relationship between the acquisition of concept and the number of subterms or the level of their relatedness. The relevance of the present dichotomy to Greenspoon and Taffel type paradigms was discussed.
