Some introductory sources on derived stimulus relations

Sources	Comment
Critchfield and Fienup (2008); Critchfield and Twyman (2014)	Relatively nontechnical introductions to stimulus equivalence in and illustrations of the applied potential of engineering emergent learning
Hayes, Barnes-Holmes, and Roche (2001)	Delineates various types of nonequivalence relations (Chapter 2) and provides an introduction to the process of transformation of function, which is an important component of emergent learning (Chapter 3)
Stewart and Roche (2013)	An introduction to the influential relational frame theory account of stimulus relations
Dougher (1998)	A clear, early explanation of the importance of transformation of function to clinical problems
Dymond and Rehfeldt (2000)	An accessible, if slightly dated, review of the literature on transformation of function
Barnes-Holmes, Finn, MacEnteggert, and Barnes-Holmes (in press); Stewart (2017)	Nice introductions to derived stimulus relations, although later sections, which focus on advanced theoretical issues, may be harder for nonexperts to digest
Dougher, Twohig, and Madden (2014)	A brief survey of basic and translational research on stimulus relations
Rehfeldt and Barnes-Holmes (2009)	One of the first published attempts to systematize the possibilities of harnessing stimulus relations in behavioral programming for persons with developmental disabilities
