The Mediating Effects of Derived Relational Responding on the Relationship Between Verbal Operant Development and IQ

摘要

Dixon, Belisle, and Stanley, () demonstrated a strong, significant relationship between derived relational responding and intelligence in individuals with autism. We extended these results by evaluating the degree to which participant results on the PEAK Equivalence Pre-assessment (PEAK-E-PA, a direct assessment of derived relational responding) mediated the relationship between the PEAK Direct Training Assessment (PEAK-DT-A, a Skinnerian-based assessment of verbal development) and intelligence. Results support strong, positive correlations between both assessments (PEAK-DT-A and PEAK-E-PA) and IQ; however, the relationship between PEAK-DT-A and IQ could be explained in terms of participant results on the PEAK-E-PA alone. This finding corresponds with Relational Frame Theory, suggesting that derived responding can provide a behavioral interpretation of intelligent behavior, as well as Skinner’s elementary operants.
