F. Carpentier et al., Matching compound samples with unitary comparisons: Derived stimulus relations in adults and children, PSYCHOL REC, 50(4), 2000, pp. 671-685
This research investigated emergent stimulus relations produced by match-to
-sample tasks with compound samples and unitary comparisons. The study was
a modified replication of the Markham and Dougher study (1993) and consiste
d of two experiments. Four adults participated in Experiment 1, and 12 6- t
o Ii-year-old children in Experiment 2. Both experiments involved the same
training and testing sequence: Training of four AB-C relations (A1B1-C1, A2
B2-C1, A1B2-C2, A2B1-C2), followed by C-AB tests (symmetry) and BC-A or AC-
B tests, C-D training (C1-D1, C2-D2), DC tests, D-AB tests (equivalence), a
nd AD-B or ED-A tests. All 16 subjects demonstrated class-consistent C-AS a
nd class-like AC-B or BC-A relations. Of these subjects, 15 also demonstrat
ed class-consistent D-AB and class-like ED-A or AD-B relations.
