McHugh, L., Barnes-Holmes, Y., & Barnes-Holmes, D. (2004). Perspective-taking as relational responding: A developmental profile. The Psychological Record, 54, 115-144.
The authors, researchers at the National University of Ireland, propound that the relational frames of I-YOU, HERE-THERE, and NOW-THEN are central to the development of complex perspective-taking. The present paper reports 3 studies that investigate the development of perspective-taking in terms of these 3 relational frames. Overall, the findings from the 3 studies lend support to the Relational Frame approach to the development of perspective-taking as generalized operant behavior.
