Abstract
The present study sought to compare the relationship between the generalization skills and performance on a standardized IQ assessment on 30 individuals with developmental or intellectual disabilities (73% had a diagnosis of autism). Participants’ generalization skills were tested using the Promoting the Emergence of Advanced Knowledge Generalization Module (PEAK-G), 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 scores on the PEAK-G and IQ using both Raw IQ (r = .839, p > .01) and Full Scale IQ (r = .628, p > .01). Both Raw IQ and Full Scale IQ were further analyzed by comparing them each to the three subtests of the PEAK-G (Foundational Learning and Basic Social Skills, Verbal Comprehension, Memory and Advanced Social Skills and Verbal Reasoning, Problem Solving, and Advanced Mathematical Skills). The results help to provide a better understanding of how closely participants’ IQ scores correlate to their PEAK-G scores.
