| Popis: | Stimuli in equivalence classes are functionally interchangeable, and thus suggest that the class members are equally related to each other. A growing number of experimental findings, however, have shown that under appropriate conditions of testing, the relational strength of the stimuli in an equivalence class may be determined by the nodal structure of the class and the number of nodes the separate the stimuli in a multinodal class. Data that support this view have been obtained (a) during the delayed emergence of classes, (b) during gradual transfer of functions after class formation, (c) from the reaction times displayed by derived relations that varied in nodal number during and after class formation, (d) by derived relations in the absence of class formation, (e) from retrospective reports of reinforcer presentations during derived relations probes, (f) from brain imaging studies that showed unique areas of cortical activation produced by post-class formation probes of baseline and derived relations,... |
