In two experiments, the effects of materials in response (words vs. nonsense syllables) and amount of training on transfer were investigated in the A-B, A-Br1, A-Br2 paradigm. There was no transfer effect regardless of the materials and amount of training in trial scores, Negative transfer in error scores occurred in A-Br1 list with words list, but positive transfer increased gradually as a function of number of re-paired lists with nonsense syllable list, Facilitating effects of overlearning were shown in both materials. These results were explained in terms of response availability and search or editing process.
