The function at play would vary in accordance with a background color ( Cfunc ) e.g., If yellow, given A1, press “Z” e.g., If blue, given A1, press “X”... When the background colors were established as equivalent to certain line patterns (horizontal and vertical), such line patterns acquired the same function (Cfunc) of the background colors.

26. www.nucleoparadigma.com.brwww.nucleoparadigma.com.br contato@nucleoparadigma.com.brcontato@nucleoparadigma.com.br DISCUSSION The present study investigated the transfer of contextual-cue function (Crel) for sameness and opposition through equivalence classes. The results of 5 participants suggest that Crel function might be indirectly acquired via transformation (or transfer) of function. These results extend previous findings (e.g., Gatch & Osborne, 1989; Perez et al., 2012) on different contextual-stimulus functions that might be transferred through equivalence classes: Contextual cues that (re)organize classes (Gatch & Osborne, 1989) Cfunc (Perez et al., 2012) Crel (present study)

27. www.nucleoparadigma.com.brwww.nucleoparadigma.com.br contato@nucleoparadigma.com.brcontato@nucleoparadigma.com.br DISCUSSION 5 participants didn’t pass on the derivation tests even after repeating the procedure several times. Some of them seamed to respond to contextually controlled equivalence classes (see Bush, Sidman, & de Rose, 1989; Gatch & Osborne, 1989) instead of relational networks based on sameness and opposition. Future studies should: investigate the effects of the number of exemplars used to establish the contextual cues upon the performance on the derivation test. reverse the relational networks in order to corroborate the effects of the type of relation established on the transformation of function tests (Whelan & Barnes- Holmes, 2004). investigate the transformation (not the transfer) of contextual-cue functions

28. www.nucleoparadigma.com.brwww.nucleoparadigma.com.br contato@nucleoparadigma.com.brcontato@nucleoparadigma.com.br DISCUSSION The transformation of function, a fundamental feature of derived relational responding (Hayes et al., 2001; Whelan & Barnes, 2004), was attested by the transformation of meanings attributed to the arbitrary stimuli. Future study should keep investigating how transformation of function can be verbally measured in tests of this sort (e.g., Bortoloti & de Rose, 2009).

29. www.nucleoparadigma.com.brwww.nucleoparadigma.com.br contato@nucleoparadigma.com.brcontato@nucleoparadigma.com.br DISCUSSION In order to account for the complexity of language and cognition, studies should consider that the expansion of relational networks might involve not only the stimuli that are related but also the contextual cues that specify the type of relational responding involved - i.e. contextual cues themselves (Cfunc, Crel) might also be part of relational networks and have their functions transformed.

30. www.nucleoparadigma.com.brwww.nucleoparadigma.com.br contato@nucleoparadigma.com.brcontato@nucleoparadigma.com.br DISCUSSION ACT interventions do not aim to change relational networks or stimulus functions themselves. Instead, their goal is to change the context in which such functions occur. Comprehending how contextual functions (Cfun, Crel) work and how they can be transformed is an important step in order to account for the behavioral processes involved in ACT interventions. The present study is a small step in this direction.
