The present study examined the relationship between performance on standard FB (SFB) tests, nonvocal FB (NFB) tests, and the Guesser-Knower (GK) test which is designed to measure understanding of the relationship between seeing and knowing. Twenty children with diagnoses of autism spectrum disorders were tested on 2 SFB tests, 2 NFB tests, and the GK test. The results replicated previous research in that 75% of the children tested were unable to peform the SFB tests. Approximately 17% of the children who failed the SFB tests passed the NFB test. Only 5% of the children who failed the SFB test and none of the children who failed the NFB test passed the GK task. A positive and moderate correlation (.77) was found between expressive language age equivalent and performance on the SFB test. Procedural reliability (PR) was calculated for 69% of the assessments and inter-observer agreement scores (IOA) were calculated for 72% of the assessments. PR scores averaged 94% and IOA scores averaged 95%.
