Abstract
-
Three experiments were conducted to evaluate the effects of nodal distance using within-class-preference tests. In Experiment 1, two 2-node 4-member equivalence classes were established using the simultaneous protocol. In this procedure all of the baseline relations were trained together, after which all emergent relations probes were presented together. During equivalence class training and testing, trials were presented using match-to-sample trials that contained two comparisons. After class formation, the effects of nodal distance were evaluated using within-class preference tests which yielded inconsistent test performances. Experiment 2 replicated Experiment 1 with one exception. A third comparison was used in the establishment of the two equivalence classes under the simultaneous protocol. The subsequent within-class probes then produced the immediate emergence of performances that were consistent with the predicted effects of nodal distance. Experiment 3 was conducted to test for the generality of the findings observed in Experiment 2. The participants formed two 3-node 5-member classes under the simultaneous protocol, and once again demonstrated the effects of nodal distance using probes that assessed larger nodal spreads than those found in 4-member classes.
