The Training and Assessment of Relational Precursors and Abilities (TARPA; Moran, Stewart, McElwee & Ming, 2010, 2014; Moran, Walsh, Stewart, McElwee & Ming, 2015) is an efficient, evidence-based tool for assessing and training a number of key forms of responding, including both prerequisites to derived relational responding (DRR) as well as aspects of DRR itself. As an assessment tool, the TARPA (both in its full form and in a modified form testing only one of the stimulus modality tracks) has been shown to have strong and significant correlations with the Vineland Adaptive Behavior Scales (Moran et al., 2010), the Preschool Language Scale 4th edition (Moran et al., 2014, 2015), and the Stanford-Binet 5th edition (Moran et al., 2015). The TARPA has also been used to train relational framing skills (Ming, 2015) and to demonstrate the effects of context on the assessment of derived relational responding (Ming, Stewart, McElwee & Bynum, 2015).

The TARPA is divided into a number of assessment and training tasks, including basic discrimination, non-arbitrary conditional discrimination (identity), arbitrary conditional discrimination, and the defining properties of relational framing: mutually entailed relational responding, combinatorially entailed relational responding and transformation of function. Within each of these, users can select to assess or train using either visual stimuli, auditory stimuli, or combinations of visual and auditory stimuli, and to use either abstract (nonsense words or abstract symbols) or familiar stimuli (pictures of real-life animals, food, or houses). The combinations of stimuli and modality allows for the assessment of very early repertoires through well-generalized equivalence responding.

We are excited for you to use the TARPA.

It is in beta, and may have bugs – so please report those to: tarpabugs@hedgehogpublishers.com
