Behavioral findings in children and adults. A significantly greater percentage of CRs was exhibited during conditioning relative to pseudoconditioning, indicating that both groups learned the CS‐US association. Between session contrasts: % CRs in each session labeled “b” was significantly greater (at P < 0.05) than during pseudoconditioning, which is labeled “a.” Between group contrasts: adults produced significantly more CRs than children during sessions 1 and 2 (**P < 0.01; *P < 0.05).
