Vocalizing phonologically correct non-word stimuli during equivalence class formation

ABSTRACT

Some attempts were made in an evolving set of four small experiments to track the formation of stimulus equivalence relations where these appeared to emerge during testing, after initial training of AB and BC base relations. In this simple linear training structure, it was postulated that some kind of access would be needed, on CA equivalence tests, to the absent nodal B stimuli, which provided the links between the base pairs. The roles of “recognition” and “recall” of stimuli were examined in a number of ways during training, during testing and after testing, including the use of a simplified form of protocol analysis made possible using phonologically correct non-words as stimuli, designed to be low in meaning but readily able to be pronounced aloud. Some interesting individual differences came to light, which, it is argued, deserve further exploration with other and more complex training structures using some of the methods described.
