Derived Relational Responding and Intelligence: Assessing the Relationship Between the PEAK-E Pre-assessment and IQ with Individuals with Autism and Related Disabilities

Abstract

The present study evaluated the relationship between derived relational responding demonstrated by 64 individuals with developmental or intellectual disabilities (90.63% of which had an autism diagnosis) and their corresponding performance on standardized IQ assessments. Participants’ relational abilities were assessed using the Promoting the Emergence of Advanced Knowledge Equivalence Pre-Assessment (PEAK-E-PA), and IQ was assessed using either the WISC-IV Short Form assessment or the WPPSI-III Short Form assessment. The data indicated a strong, significant correlation between participant scores on the PEAK-E-PA and IQ both in terms of raw IQ (r =.843, p <.01), as well as full scale IQ (r =.804, p <.01), which is further analyzed in terms of each of the four subtests of the PEAK-E-PA (reflexivity, symmetry, transitivity, and equivalence). The obtained results have implications for a behavior analytic understanding of factors that relate to the development of intelligent behavior in individuals with disabilities.
