Relational Frame Theory (RFT) focuses on how relational networks help people acquire linguistic and cognitive skills. The definitions of topographical equivalency, chronological equivalency, and functional equivalency may be treated differently if we frame your inquiry in terms of relational frames. In general, these ideas would be understood as follows:
1. **Topographical Equivalency**: This phrase usually refers to the sameness or physical likeness of actions or reactions. It would be more about how similar stimuli are related in terms of their features or properties within a relational network in the context of relational frames than it would be about physical form.
2. **Temporal Equivalency**: This refers to how actions or stimuli are timed or arranged. It may be used to describe the temporal ordering of behaviors or occurrences in relation to one another in relational frames, highlighting the temporal relations (before, after) between stimuli.
3. **Functional Equivalence**: Different actions that accomplish the same goal or fulfill the same purpose are referred to be functionally equivalent in ABA and RFT. This would imply that, in relational frames, various stimuli or responses could be functionally interchangeable depending on the effects they have on the surroundings or the reactions they evoke in other people.
Rather than emphasizing the immediate visible aspects that are frequently stressed in standard ABA, these notions employed in RFT place more emphasis on the abstract or cognitive connections between stimuli.
