The aim of this study was to provide a demonstration of
equivalence-equivalence responding based on the abstraction of
common formal properties, thus extending the functional-analytic
model of analogical reasoning shown by Barnes, Hegarty, and
Smeets (1997). In Experiment 1, 9 college students were taught,
using a delayed matching-to-sample procedure, to choose a
particular nonsense syllable in the presence of each of four blue and
four red geometric shapes. In a subsequent test, all 9 subjects
demonstrated equivalence formation based on the abstraction of
color by consistently matching nonsense syllables related to samecolored
shapes to each other. Of these 9 subjects, 8 then showed
equivalence-equivalence responding in which equivalence relations
from the previous part of the experiment were related to other
equivalence relations and nonequivalence relations were related to
other nonequivalence relations. In Experiment 2, 3 out of 4 additional
subjects showed this analogical-type responding based on larger
relational networks than those established in Experiment 1, and in
Experiment 3, 3 further subjects showed analogical responding
based on the abstraction of the relatively complex property of age.
