Deictic Framing Performance Fails to Generalize to Other Perspective-Taking Tasks

Abstract

The behavioral processes underlying perspective taking have not been studied extensively. One approach to understanding and enhancing perspective taking, deictic framing, has been proposed. Proponents of this approach have suggested that deictic framing is a core property of perspective taking. A training protocol based on deictic framing has been developed and tested, but researchers generally evaluate the effectiveness of the protocol using tasks that have a similar format to the training protocol. Little research has examined the protocol’s effectiveness for improving performance in different perspective-taking tasks. We investigated generalization of the performance of three groups of university students trained with a deictic-framing protocol (or not) and tested with two other perspective-taking tasks: a visuospatial perspective taking using a cupboard containing a range of objects and a version of the implicit relational assessment procedure specifically designed to measure perspective taking. The first group was trained with the original verbal protocol with deictic expressions; the second group with the same protocol involving nondeictic words; and the third group was merely exposed to deictic expressions as a control condition. The results suggested that deictic framing is not fundamental to perspective taking, as the performance of the two experimental groups was not significantly different from the control group’s performance. Identification of specific stimulus functions involved in successful perspective taking and how those functions can be established should be addressed in future research.
