“…Our overall findings provide further empirical support for the relational triangulation (RT) framework (Guinther, ) of Relational Frame Theory (RFT; Hayes, Barnes‐Holmes, & Roche, ), which is an alternative to the established deictic relational frame (DRF) framework of RFT (see Montoya‐Rodríguez, Molina, & McHugh, ). False belief attribution has been studied under the DRF framework by McHugh, Barnes‐Holmes, Barnes‐Holmes, and Stewart (), who found that accuracy of responding to a modified version of the linguistic McHugh, Barnes‐Holmes perspective taking protocol (MBH‐PTP) was predicted by age, in the range of 3‐30 years.…”
